Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business, Basis of Presentation, and Changes in Significant Accounting Policies	Description of Business, Basis of Presentation, and Changes in Significant Accounting Policies Ally Financial Inc. (together with its consolidated subsidiaries unless the context otherwise requires, Ally, the Company, we, us, or our) is a digital financial-services company committed to its promise to “Do It Right” for its consumer, commercial, and corporate customers. Ally is composed of an industry-leading independent automotive finance and insurance operation, an award-winning digital direct bank (Ally Bank, Member FDIC and Equal Housing Lender, which offers mortgage lending, point-of-sale personal lending, and a variety of deposit and other banking products), a consumer credit card business, a corporate finance business for equity sponsors and middle-market companies, and securities brokerage and investment advisory services. We are a Delaware corporation and are registered as a BHC under the BHC Act, and an FHC under the GLB Act. Our accounting and reporting policies conform to U.S. GAAP. Additionally, where applicable, the policies conform to the accounting and reporting guidelines prescribed by bank regulatory authorities. Certain reclassifications may have been made to the prior periods’ financial statements and notes to conform to the current period’s presentation, which did not have a material impact on our Condensed Consolidated Financial Statements. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and that affect income and expenses during the reporting period and related disclosures. In developing the estimates and assumptions, management uses all available evidence; however, actual results could differ because of uncertainties associated with estimating the amounts, timing, and likelihood of possible outcomes. Our most significant estimates pertain to the allowance for loan losses, valuations of automotive lease assets and residuals, fair value of financial instruments, and the determination of the provision for income taxes. The Condensed Consolidated Financial Statements at March 31, 2022, and for the three months ended March 31, 2022, and 2021, are unaudited but reflect all adjustments that are, in management’s opinion, necessary for the fair presentation of the results for the interim periods presented. All such adjustments are of a normal recurring nature. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements (and the related Notes) included in our Annual Report on Form 10-K for the year ended December 31, 2021, as filed on February 25, 2022, with the SEC. Significant Accounting Policies Income Taxes In calculating the provision for interim income taxes, in accordance with ASC 740, Income Taxes , we apply an estimated annual effective tax rate to year-to-date ordinary income. At the end of each interim period, we estimate the effective tax rate expected to be applicable for the full fiscal year. This method differs from that described in Note 1 to the Consolidated Financial Statements in our 2021 Annual Report on Form 10-K, which describes our annual significant income tax accounting policy and related methodology. Refer to Note 1 to the Consolidated Financial Statements in our 2021 Annual Report on Form 10-K regarding additional significant accounting policies. Recently Issued Accounting Standards Fair Value Hedging—Portfolio Layer Method (ASU 2022-01) In March 2022, the FASB issued ASU 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method . The purpose of this guidance is to expand the current last-of-layer method to allow multiple hedged layers of a single closed portfolio. This change will allow hedge accounting to be achieved using different types of derivatives and layering techniques, including the use of amortizing swaps with clarification that such a trade would be viewed as being a single layer. Under this expanded scope, both prepayable and nonprepayable financial assets may be included in a single closed portfolio hedge. In addition, the guidance provides clarifications to breach requirements and disclosures. As a result of this change, the last-of-layer method has been renamed the portfolio layer method. The amendments are effective on January 1, 2023, with early adoption permitted. The amendments must be applied using a prospective approach and will not have a material impact upon adoption. Troubled Debt Restructurings and Vintage Disclosures (ASU 2022-02) In March 2022, the FASB issued ASU 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures . The purpose of this guidance is twofold. First, the guidance eliminates TDR recognition and measurement guidance that has been deemed no longer necessary under CECL. The guidance also adds a requirement to incorporate current year gross charge-offs by origination year into the vintage tables. With respect to the TDR impacts, under CECL, credit losses for financial assets measured at amortized cost are determined based on the total current expected credit losses over the life of the financial asset or group of financial assets. Therefore, credit losses on financial assets that have been modified as TDRs would have largely been incorporated in the allowance upon initial recognition. Under ASU 2022-02, we will be required to evaluate whether loan modifications previously characterized as TDRs represent a new loan or a continuation of an existing loan in accordance with ASC Topic 310, Receivables . The guidance also adds new disclosures that will require an entity to provide information related to loan modifications that are made to borrowers that are deemed to be in financial difficulty. The amendments are effective on January 1, 2023, with early adoption permitted. The amendments must be applied using a prospective approach; however, for the transition away from TDRs, the amendments may be adopted using a modified retrospective approach with a cumulative-effect adjustment through retained earnings as of the beginning of the fiscal year upon adoption. Management is currently evaluating the impact of these amendments.

Business Combination and Asset Acquisition [Abstract]
Acquisitions	Acquisitions On December 1, 2021, we acquired 100% of the equity of Fair Square Financial Holdings LLC and its subsidiaries, including Fair Square Financial LLC (collectively, Fair Square) for $741 million in cash. Fair Square, which we rebranded Ally Credit Card, is a digital-first, nonbank credit-card company that operates in the United States. Fair Square operates as a wholly owned subsidiary of Ally. We applied the acquisition method of accounting to this transaction, which generally requires the initial recognition of assets acquired, including identifiable intangible assets, and liabilities assumed at their respective fair value. Goodwill is recognized as the excess of the acquisition price after the recognition of the net assets, including the identifiable intangible assets. Beginning in December 2021, financial information related to Fair Square is included within Corporate and Other. The following table summarizes the allocation of cash consideration paid for Fair Square and the amounts of the identifiable assets acquired and liabilities assumed at the acquisition date. ($ in millions) Purchase price Cash consideration $ 741 Allocation of purchase price to net assets acquired Finance receivables and loans (a) 870 Intangible assets (b) 98 Cash and short-term investments 42 Other assets 46 Debt (765) Other liabilities (29) Goodwill $ 479 (a) Includes $22 million of PCD loans that have experienced a more-than-insignificant deterioration of credit quality since origination. We recognized an initial allowance for loan losses of $12 million on these PCD loans. (b) The weighted average amortization period on the acquired intangible assets is 7 years. Refer to Note 11 for further information on our intangible assets. The goodwill of $479 million arising from the acquisition consists largely of expected growth of the business as we leverage the Ally brand and our marketing capabilities to scale the acquired credit card provider and expand the suite of financial products we offer to our existing growing customer base. The goodwill recognized is generally expected to be amortized for income tax purposes over a 15-year period. Refer to Note 11 for the carrying amount of goodwill at the beginning and end of the reporting period.

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Revenue from Contracts with Customers Our primary revenue sources, which include financing revenue and other interest income, are addressed by other GAAP and are not in the scope of ASC Topic 606, Revenue from Contracts with Customers. As part of our Insurance operations, we recognize revenue from insurance contracts, which are addressed by other GAAP and are not included in the scope of this standard. Certain noninsurance contracts within our Insurance operations, including VSCs, GAP contracts, and VMCs, are included in the scope of this standard. All revenue associated with noninsurance contracts is recognized over the contract term on a basis proportionate to the anticipated cost emergence. Further, commissions and sales expense incurred to obtain these contracts are amortized over the terms of the related policies and service contracts on the same basis as premiums and service revenue are earned, and all advertising costs are recognized as expense when incurred. The following table presents a disaggregated view of our revenue from contracts with customers. For further information regarding our revenue recognition policies and details about the nature of our respective revenue streams, refer to Note 1 and Note 3 to the Consolidated Financial Statements in our 2021 Annual Report on Form 10-K.

(b) At March 31, 2022, we had unearned revenue of $3.0 billion associated with outstanding contracts, and with respect to this balance we expect to recognize revenue of $648 million during the remainder of 2022, $794 million in 2023, $644 million in 2024, $448 million in 2025, and $490 million thereafter.

(d) Effective May 25, 2021, we eliminated all overdraft fees for Ally Bank deposit accounts. (e) Interchange income is reported net of customer rewards.

This analysis considered a variety of factors including, but not limited to, performance indicators of the issuer, default rates, industry analyst reports, credit ratings, and other relevant information, which indicated that contractual cash flows are expected to occur. As a result of this evaluation, management determined that no credit reserves were required at March 31, 2022, or December 31, 2021.

We evaluate the credit quality of our commercial loan portfolio using regulatory risk ratings, which are based on relevant information about the borrower’s financial condition, including current financial information, historical payment experience, credit documentation, and current economic trends, among other factors. We use the following definitions for risk rankings below Pass. • Special mention — Loans that have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or the institution’s credit position at some future date. • Substandard — Loans that are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. These loans have a well-defined weakness or weakness that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. • Doubtful — Loans that have all the weaknesses inherent in those classified as substandard, with the additional characteristic that the weaknesses make collection or liquidation in full, based on the basis of currently existing facts, conditions, and values, highly questionable and improbable. The regulatory risk classification utilized is influenced by internal credit risk ratings, which are based on a variety of factors. A borrower’s internal credit risk rating is updated at least annually, and more frequently when a borrower’s credit profile changes, including when we become aware of potential credit deterioration.

For consumer automotive loans, we may offer several types of assistance to aid our customers, including payment extensions and rewrites of the loan terms. Additionally, for mortgage loans, as part of certain programs, we offer mortgage loan modifications to qualified borrowers. These programs are in place to provide support to our mortgage customers in financial distress, including principal forgiveness, maturity extensions, delinquent interest capitalization, and changes to contractual interest rates. Total TDRs recorded at amortized cost were $2.3 billion and $2.4 billion at March 31, 2022, and December 31, 2021, respectively. Total commitments to lend additional funds to borrowers whose terms had been modified in a TDR were $19 million and $18 million at March 31, 2022, and December 31, 2021, respectively.

Leasing	3 Months Ended

Leases [Abstract]
Leasing	Leasing Ally as the Lessee We have operating leases for our corporate facilities, which have remaining lease terms of 4 months to 7 years. Most of the property leases have fixed payment terms with annual fixed-escalation clauses and include options to extend the leases for periods that range from 1 to 15 years. Some of those lease agreements also include options to terminate the leases in periods that range from approximately 5 to 6 years after the commencement of the leases. We have not included any of these term extensions or termination provisions in our estimates of the lease term, as we do not consider it reasonably certain that the options will be exercised. We also have operating leases for a fleet of vehicles that is used by our sales force for business purposes, with noncancelable lease terms of 367 days. Thereafter, the leases are month-to-month, up to a maximum of 48 months from inception. During the three months ended March 31, 2022, and March 31, 2021, we paid $10 million and $13 million, respectively, in cash for amounts included in the measurement of lease liabilities. These amounts are included in net cash provided by operating activities in the Condensed Consolidated Statement of Cash Flows. During the three months ended March 31, 2022, and March 31, 2021, we obtained $12 million and $337 million, respectively, of ROU assets in exchange for new lease liabilities. As of March 31, 2022, the weighted-average remaining lease term of our operating lease portfolio was 5 years, and the weighted-average discount rate was 2.14%, compared to 6 years and 1.96% as of December 31, 2021. The following table presents future minimum rental payments we are required to make under operating leases that have commenced as of March 31, 2022, and that have noncancelable lease terms expiring after March 31, 2022.

We provided notice of our intent to exercise the purchase option in April 2021, and executed on the purchase agreement in July 2021. Additionally, we agreed to lease a portion of this corporate facility in exchange for $13 million in future lease payments over a ten year lease term. In February 2022, we provided notice of our intent to exercise the purchase option for an operations center in Lewisville, Texas, which consisted of a leased facility. Upon exercise of the purchase option, the lease was reassessed and presented as a financing lease at March 31, 2022. The lease liability includes payments inherent in the purchase obligation totaling $42 million. The expense associated with the lease for the period in which it met the criteria for classification as a finance lease was not material. The purchase is scheduled to close in 2022. The following table details the components of total net operating lease expense. Three months ended March 31, ($ in millions) 2022 2021 Operating lease expense $ 8 $ 12 Variable lease expense 1 2 Total lease expense, net (a) $ 9 $ 14 (a) Included in other operating expenses in our Condensed Consolidated Statement of Comprehensive Income. Ally as the Lessor Investment in Operating Leases We purchase consumer operating lease contracts and the associated vehicles from dealerships after those contracts are executed by the dealers and the consumers. The amount we pay a dealer for an operating lease contract is based on the negotiated price for the vehicle less vehicle trade-in, down payment from the consumer, and available automotive manufacturer incentives. Under the operating lease, the consumer is obligated to make payments in amounts equal to the amount by which the negotiated purchase price of the vehicle (less any trade-in value, down payment, or available manufacturer incentives) exceeds the contract residual value (including residual support) of the vehicle at lease termination, plus operating lease rental charges. The customer can terminate the lease at any point after commencement, subject to additional charges and fees. Both the consumer and the dealership have the option to purchase the vehicle at the end of the lease term, which can range from 24 to 60 months, at the residual value of the vehicle, however it is not reasonably certain this option will be exercised and accordingly our consumer leases are classified as operating leases. In addition to the charges described above, the consumer is generally responsible for certain charges related to excess mileage or excessive wear and tear on the vehicle. These charges are deemed variable lease payments and, as these payments are not based on a rate or index, they are recognized as net depreciation expense on operating lease assets in our Condensed Consolidated Statement of Comprehensive Income as incurred. When we acquire a consumer operating lease, we assume ownership of the vehicle from the dealer. We require that property damage, bodily injury, collision, and comprehensive insurance be obtained by the lessee on all consumer operating leases. Neither the consumer nor the dealer is responsible for the value of the vehicle at the time of lease termination. When vehicles are not purchased by customers or the receiving dealer at scheduled lease termination, the vehicle is returned to us for remarketing. We generally bear the risk of loss to the extent the value of a leased vehicle upon remarketing is below the expected residual value. At termination, our actual sales proceeds from remarketing the vehicle may be higher or lower than the estimated residual value resulting in a gain or loss on remarketing, which is included in net depreciation expense on operating lease assets in our Condensed Consolidated Statement of Comprehensive Income. Excessive mileage or excessive wear and tear on the vehicle during the lease may impact the sales proceeds received upon remarketing. As of March 31, 2022, and December 31, 2021, consumer operating leases with a carrying value, net of accumulated depreciation, of $120 million and $165 million, respectively, were covered by a residual value guarantee of 15% of the manufacturer’s suggested retail price. The following table details our investment in operating leases.

Depreciation expense on operating lease assets includes net remarketing gains recognized on the sale of operating lease assets. The following table summarizes the components of depreciation expense on operating lease assets.

Finance Leases In our Automotive Finance operations, we also hold automotive leases that require finance lease treatment as prescribed by ASC Topic 842, Leases . Our total gross investment in finance leases, which is included in finance receivables and loans, net, on our Condensed Consolidated Balance Sheet was $461 million and $470 million as of March 31, 2022, and December 31, 2021, respectively. This includes lease payment receivables of $448 million and $457 million at March 31, 2022, and December 31, 2021, respectively, and unguaranteed residual assets of $13 million at both March 31, 2022, and December 31, 2021, respectively. Interest income on finance lease receivables was $7 million for the three months ended March 31, 2022, and $6 million for the three months ended March 31, 2021, and is included in interest and fees on finance receivables and loans in our Condensed Consolidated Statement of Comprehensive Income.

Leasing	Leasing Ally as the Lessee We have operating leases for our corporate facilities, which have remaining lease terms of 4 months to 7 years. Most of the property leases have fixed payment terms with annual fixed-escalation clauses and include options to extend the leases for periods that range from 1 to 15 years. Some of those lease agreements also include options to terminate the leases in periods that range from approximately 5 to 6 years after the commencement of the leases. We have not included any of these term extensions or termination provisions in our estimates of the lease term, as we do not consider it reasonably certain that the options will be exercised. We also have operating leases for a fleet of vehicles that is used by our sales force for business purposes, with noncancelable lease terms of 367 days. Thereafter, the leases are month-to-month, up to a maximum of 48 months from inception. During the three months ended March 31, 2022, and March 31, 2021, we paid $10 million and $13 million, respectively, in cash for amounts included in the measurement of lease liabilities. These amounts are included in net cash provided by operating activities in the Condensed Consolidated Statement of Cash Flows. During the three months ended March 31, 2022, and March 31, 2021, we obtained $12 million and $337 million, respectively, of ROU assets in exchange for new lease liabilities. As of March 31, 2022, the weighted-average remaining lease term of our operating lease portfolio was 5 years, and the weighted-average discount rate was 2.14%, compared to 6 years and 1.96% as of December 31, 2021.

We provided notice of our intent to exercise the purchase option in April 2021, and executed on the purchase agreement in July 2021. Additionally, we agreed to lease a portion of this corporate facility in exchange for $13 million in future lease payments over a ten year lease term. In February 2022, we provided notice of our intent to exercise the purchase option for an operations center in Lewisville, Texas, which consisted of a leased facility. Upon exercise of the purchase option, the lease was reassessed and presented as a financing lease at March 31, 2022. The lease liability includes payments inherent in the purchase obligation totaling $42 million. The expense associated with the lease for the period in which it met the criteria for classification as a finance lease was not material. The purchase is scheduled to close in 2022. The following table details the components of total net operating lease expense.

Ally as the Lessor Investment in Operating Leases We purchase consumer operating lease contracts and the associated vehicles from dealerships after those contracts are executed by the dealers and the consumers. The amount we pay a dealer for an operating lease contract is based on the negotiated price for the vehicle less vehicle trade-in, down payment from the consumer, and available automotive manufacturer incentives. Under the operating lease, the consumer is obligated to make payments in amounts equal to the amount by which the negotiated purchase price of the vehicle (less any trade-in value, down payment, or available manufacturer incentives) exceeds the contract residual value (including residual support) of the vehicle at lease termination, plus operating lease rental charges. The customer can terminate the lease at any point after commencement, subject to additional charges and fees. Both the consumer and the dealership have the option to purchase the vehicle at the end of the lease term, which can range from 24 to 60 months, at the residual value of the vehicle, however it is not reasonably certain this option will be exercised and accordingly our consumer leases are classified as operating leases. In addition to the charges described above, the consumer is generally responsible for certain charges related to excess mileage or excessive wear and tear on the vehicle. These charges are deemed variable lease payments and, as these payments are not based on a rate or index, they are recognized as net depreciation expense on operating lease assets in our Condensed Consolidated Statement of Comprehensive Income as incurred. When we acquire a consumer operating lease, we assume ownership of the vehicle from the dealer. We require that property damage, bodily injury, collision, and comprehensive insurance be obtained by the lessee on all consumer operating leases. Neither the consumer nor the dealer is responsible for the value of the vehicle at the time of lease termination. When vehicles are not purchased by customers or the receiving dealer at scheduled lease termination, the vehicle is returned to us for remarketing. We generally bear the risk of loss to the extent the value of a leased vehicle upon remarketing is below the expected residual value. At termination, our actual sales proceeds from remarketing the vehicle may be higher or lower than the estimated residual value resulting in a gain or loss on remarketing, which is included in net depreciation expense on operating lease assets in our Condensed Consolidated Statement of Comprehensive Income. Excessive mileage or excessive wear and tear on the vehicle during the lease may impact the sales proceeds received upon remarketing. As of March 31, 2022, and December 31, 2021, consumer operating leases with a carrying value, net of accumulated depreciation, of $120 million and $165 million, respectively, were covered by a residual value guarantee of 15% of the manufacturer’s suggested retail price.

Securitizations And Variable Interest Entities [Abstract]
Securitizations and Variable Interest Entities	Securitizations and Variable Interest Entities We securitize, transfer, and service consumer and commercial automotive loans. We often securitize these loans (also referred to as financial assets) using SPEs. An SPE is a legal entity that is designed to fulfill a specified limited need of the sponsor. Our principal use of SPEs is to obtain liquidity by securitizing certain of our financial assets. SPEs are often VIEs and may or may not be included on our Condensed Consolidated Balance Sheet. VIEs are legal entities that either have an insufficient amount of equity at risk for the entity to finance its activities without additional subordinated financial support or, as a group, the holders of the equity investment at risk lack the ability to control the entity’s activities that most significantly impact economic performance through voting or similar rights, or do not have the obligation to absorb the expected losses or the right to receive expected residual returns of the entity. The VIEs included on the Condensed Consolidated Balance Sheet represent SPEs where we are deemed to be the primary beneficiary, primarily due to our servicing activities and our beneficial interests in the VIE that could be potentially significant. The nature, purpose, and activities of nonconsolidated SPEs are similar to those of our consolidated SPEs with the primary difference being the nature and extent of our continuing involvement. For nonconsolidated SPEs, the transferred financial assets are removed from our balance sheet provided the conditions for sale accounting are met. The financial assets obtained from the securitization are primarily reported as cash or retained interests (if applicable). Liabilities incurred as part of these securitizations, are recorded at fair value at the time of sale and are reported as accrued expenses and other liabilities on our Condensed Consolidated Balance Sheet. Upon the sale of the loans, we recognize a gain or loss on sale for the difference between the assets recognized, the assets derecognized, and the liabilities recognized as part of the transaction. With respect to our ongoing right to service the assets we sell, the servicing fee we receive represents adequate compensation, and consequently, we do not recognize a servicing asset or liability. There were no sales of financial assets into nonconsolidated VIEs for both the three months ended March 31, 2022, and March 31, 2021. We provide long-term guarantee contracts to investors in certain nonconsolidated affordable housing entities and have extended a line of credit to provide liquidity. Since we do not have control over the entities or the power to make decisions, we do not consolidate the entities and our involvement is limited to the guarantee and the line of credit. We are involved with various other nonconsolidated equity investments, including affordable housing entities and venture capital funds and loan funds. We do not consolidate these entities and our involvement is limited to our outstanding investment, additional capital committed to these funds plus any previously recognized low-income housing tax credits that are subject to recapture. Refer to Note 1 and Note 11 to the Consolidated Financial Statements in our 2021 Annual Report on Form 10-K for further description of our securitization activities and our involvement with VIEs. The following table presents our involvement in consolidated and nonconsolidated VIEs in which we hold variable interests. We have excluded certain transactions with nonconsolidated entities from the balances presented in the table below, where our only continuing involvement relates to financial interests obtained through the ordinary course of business, primarily from lending and investing arrangements. For additional detail related to the assets and liabilities of consolidated variable interest entities refer to the Condensed Consolidated Balance Sheet.

The amount disclosed is based on the unlikely event that the yield delivered to investors in the form of low-income tax housing credits is recaptured. For nonconsolidated equity investments, maximum exposure to loss represents our outstanding investment, additional committed capital, and low-income housing tax credits subject to recapture. The amount disclosed is based on the unlikely event that our committed capital is funded, our investments become worthless, and the tax credits previously delivered to us are recaptured. This required disclosure is not an indication of our expected loss. (g) Represents balances from our credit card business.

Regulatory Capital and Other Re

Regulatory Capital and Other Regulatory Matters	3 Months Ended

Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract]
Regulatory Capital and Other Regulatory Matters	Regulatory Capital and Other Regulatory Matters Ally is currently subject to enhanced prudential standards that were established by the FRB under the Dodd-Frank Act. Targeted amendments to the Dodd-Frank Act and other financial-services laws were enacted through the EGRRCP Act, including amendments that affect whether and, if so, how the FRB applies enhanced prudential standards to BHCs like us with $100 billion or more but less than $250 billion in total consolidated assets. Through final rules implementing these amendments—which are commonly known as the tailoring framework—the FRB and other U.S. banking agencies established four risk-based categories of prudential standards and capital and liquidity requirements for banking organizations with $100 billion or more in total consolidated assets. The most stringent standards and requirements apply to U.S. global systemically important BHCs, which are assigned to Category I. The assignment of other banking organizations to the remaining three categories is based on measures of size and four other risk-based indicators: cross-jurisdictional activity, wSTWF, nonbank assets, and off-balance-sheet exposure. Under the tailoring framework, Ally is a Category IV firm and, as such, is (1) subject to supervisory stress testing on a two-year cycle, (2) required to submit an annual capital plan to the FRB, (3) required to maintain a buffer of unencumbered highly liquid assets to meet projected net stressed cash outflows over a 30-day planning horizon, (4) exempted from company-run capital stress testing requirements, (5) exempted from the requirements of the LCR and the net stable funding ratio provided that our average wSTWF continues to remain under $50 billion, and (6) exempted from the requirements of the supplementary leverage ratio, the countercyclical capital buffer, and single-counterparty credit limits. Refer to Note 20 to the Consolidated Financial Statements in our 2021 Annual Report on Form 10-K for additional details on the tailoring framework and other applicable capital and liquidity requirements. We continue to be subject to rules enabling the FRB to conduct supervisory stress testing on a more or less frequent basis based on our financial condition, size, complexity, risk profile, scope of operations, or activities, or risks to the U.S. economy. Further, we remain subject to rules requiring the resubmission of our capital plan if we determine that there has been or will be a material change in our risk profile, financial condition, or corporate structure since we last submitted the capital plan or if the FRB determines that (a) our capital plan is incomplete or our capital plan or internal capital adequacy process contains material weaknesses, (b) there has been, or will likely be, a material change in our risk profile (including a material change in our business strategy or any risk exposure), financial condition, or corporate structure, or (c) the BHC stress scenario(s) are not appropriate for our business model and portfolios, or changes in the financial markets or the macroeconomic outlook that could have a material impact on our risk profile and financial condition require the use of updated scenarios. Basel Capital Framework The FRB and other U.S. banking agencies have adopted risk-based and leverage capital standards that establish minimum capital-to-asset ratios for BHCs, like Ally, and depository institutions, like Ally Bank. The risk-based capital ratios are based on a banking organization’s RWAs, which are generally determined under the standardized approach applicable to Ally and Ally Bank by (1) assigning on-balance-sheet exposures to broad risk-weight categories according to the counterparty or, if relevant, the guarantor or collateral (with higher risk weights assigned to categories of exposures perceived as representing greater risk), and (2) multiplying off-balance-sheet exposures by specified credit conversion factors to calculate credit equivalent amounts and assigning those credit equivalent amounts to the relevant risk-weight categories. The leverage ratio, in contrast, is based on an institution’s average unweighted on-balance-sheet exposures. Under U.S. Basel III, Ally and Ally Bank must maintain a minimum Common Equity Tier 1 risk-based capital ratio of 4.5%, a minimum Tier 1 risk-based capital ratio of 6%, and a minimum total risk-based capital ratio of 8%. In addition to these minimum risk-based capital ratios, Ally and Ally Bank are subject to a capital conservation buffer requirement, which for Ally was 3.5% and for Ally Bank was 2.5% as of March 31, 2022, as further described in the next paragraph. Failure to maintain more than the full amount of the capital conservation buffer requirement would result in automatic restrictions on the ability of Ally and Ally Bank to make capital distributions, including dividend payments and stock repurchases and redemptions, and to pay discretionary bonuses to executive officers. U.S. Basel III also subjects Ally and Ally Bank to a minimum Tier 1 leverage ratio of 4%. Prompted by the enactment of the EGRRCP Act, the FRB and other U.S. banking agencies tailored the capital and liquidity requirements that apply to large U.S. banking organizations. In March 2020, the FRB issued a final rule to more closely align forward-looking stress testing results with the FRB’s non-stress regulatory capital requirements for BHCs with $100 billion or more in total consolidated assets and other specified companies. The final rule introduced a stress capital buffer requirement based on firm-specific stress test performance and planned dividends, which for Ally replaced the fixed 2.5% component of the capital conservation buffer requirement. The final rule also made several changes to the CCAR process effective May 2020, such as eliminating the CCAR quantitative objection, narrowing the set of planned capital actions assumed to occur in the stress scenario, assuming that a firm maintains a constant level of assets over the planning horizon, eliminating the 30% dividend payout ratio as a criterion for heightened scrutiny of a firm’s capital plan, and allowing a firm to make capital distributions in excess of those included in its capital plan if the firm is otherwise in compliance with the automatic distribution limits of the capital framework. Under the final rule, Ally’s stress capital buffer requirement is the greater of 2.5% and the result of the following calculation: (1) the difference between Ally’s starting and minimum projected Common Equity Tier 1 capital ratios under the severely adverse scenario in the supervisory stress test, plus (2) the sum of the dollar amount of Ally’s planned common stock dividends for each of the fourth through seventh quarters of its nine-quarter capital planning horizon, as a percentage of RWAs. For a Category IV firm like Ally, the capital conservation buffer requirement comprises the stress capital buffer requirement. The capital conservation buffer requirement applicable to Ally’s depository-institution subsidiary, Ally Bank, continues to be a fixed 2.5%. Ally received its first preliminary stress capital buffer requirement from the FRB in June 2020, which was determined under this new methodology to be 3.5%, was finalized in August 2020, and became effective in October 2020. In June 2020, the FRB also announced its determination that changes in financial markets or the macroeconomic outlook could have a material effect on the risk profiles and financial conditions of firms subject to the capital-plan rule and that, as a result, the firms (including Ally) would be required to resubmit capital plans to the FRB within 45 days after receiving updated stress scenarios from the FRB. On June 24, 2021, we received notification from the FRB that our stress capital buffer requirement would not be recalculated in connection with the second round of 2020 supervisory stress testing. Under applicable capital rules, the maximum amount of capital distributions and discretionary bonus payments that can be made by a banking organization, such as Ally or Ally Bank, is a function of its eligible retained income. During the COVID-19 pandemic, the FRB and other U.S. banking agencies expressed a concern that the definition of eligible retained income would not limit distributions in the gradual manner intended but instead could do so in a sudden and severe manner even if a banking organization were to experience only a modest reduction in its capital ratios. As a result, to better allow a banking organization to use its capital buffer as intended and continue lending in adverse conditions, the U.S. banking agencies issued an interim final rule that became effective in March 2020, and revised the definition of eligible retained income to the greater of (1) a banking organization’s net income for the four preceding calendar quarters, net of any distributions and associated tax effects not already reflected in net income, and (2) the average of a banking organization’s net income over the preceding four quarters. This interim final rule was adopted as final with no changes effective January 1, 2021. Ally and Ally Bank are subject to the U.S. Basel III standardized approach for counterparty credit risk but not to the U.S. Basel III advanced approaches for credit risk or operational risk. Ally is also not subject to the U.S. market-risk capital rule, which applies only to banking organizations with significant trading assets and liabilities. The risk-based capital ratios and the Tier 1 leverage ratio play a central role in PCA, which is an enforcement framework used by the U.S. banking agencies to constrain the activities of depository institutions based on their levels of regulatory capital. Five categories have been established using thresholds for the Common Equity Tier 1 risk-based capital ratio, the Tier 1 risk-based capital ratio, the total risk-based capital ratio, and the Tier 1 leverage ratio: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized. FDICIA generally prohibits a depository institution from making any capital distribution, including any payment of a cash dividend or a management fee to its BHC, if the depository institution would become undercapitalized after the distribution. An undercapitalized institution is also subject to growth limitations and must submit and fulfill a capital restoration plan. While BHCs are not subject to the PCA framework, the FRB is empowered to compel a BHC to take measures—such as the execution of financial or performance guarantees—when PCA is required in connection with one of its depository-institution subsidiaries. At both March 31, 2022, and December 31, 2021, Ally Bank was well capitalized under the PCA framework. Under FDICIA and the PCA framework, insured depository institutions such as Ally Bank must be well capitalized or, with a waiver from the FDIC, adequately capitalized in order to accept brokered deposits, and even adequately capitalized institutions are subject to some restrictions on the rates they may offer for brokered deposits. Brokered deposits totaled $4.0 billion at March 31, 2022, which represented 2.8% of Ally Bank’s total deposits. The following table summarizes our capital ratios under U.S. Basel III. March 31, 2022 December 31, 2021 Required minimum (a) Well-capitalized minimum ($ in millions) Amount Ratio Amount Ratio Capital ratios Common Equity Tier 1 (to risk-weighted assets) Ally Financial Inc. $ 14,849 9.97 % $ 15,143 10.34 % 4.50 % (b) Ally Bank 17,220 12.09 17,253 12.39 4.50 6.50 % Tier 1 (to risk-weighted assets) Ally Financial Inc. $ 17,124 11.49 % $ 17,403 11.89 % 6.00 % 6.00 % Ally Bank 17,220 12.09 17,253 12.39 6.00 8.00 Total (to risk-weighted assets) Ally Financial Inc. $ 19,564 13.13 % $ 19,724 13.47 % 8.00 % 10.00 % Ally Bank 19,006 13.34 18,995 13.64 8.00 10.00 Tier 1 leverage (to adjusted quarterly average assets) (c) Ally Financial Inc. $ 17,124 9.36 % $ 17,403 9.67 % 4.00 % (b) Ally Bank 17,220 9.93 17,253 10.12 4.00 5.00 % (a) In addition to the minimum risk-based capital requirements for the Common Equity Tier 1 capital, Tier 1 capital, and total capital ratios, Ally was required to maintain a minimum capital conservation buffer of 3.5% at both March 31, 2022, and December 31, 2021, and Ally Bank was required to maintain a minimum capital conservation buffer of 2.5% at both March 31, 2022, and December 31, 2021. (b) Currently, there is no ratio component for determining whether a BHC is “well-capitalized.” (c) Federal regulatory reporting guidelines require the calculation of adjusted quarterly average assets using a daily average methodology. On January 1, 2020, we adopted CECL, which is further described in Note 1 to the Consolidated Financial Statements in our 2021 Annual Report on Form 10-K. In December 2018, the FRB and other U.S. banking agencies approved a final rule to address the impact of CECL on regulatory capital by allowing BHCs and banks, including Ally, the option to phase in the day-one impact of CECL over a three-year period. In March 2020, the FRB and other U.S. banking agencies issued an interim final rule that became effective for the first quarter of 2020 and that provided BHCs and banks with an alternative option to temporarily delay an estimate of the impact of CECL, relative to the incurred loss methodology for estimating the allowance for loan losses, on regulatory capital. The interim final rule was clarified and adjusted in a final rule that became effective in September 2020. We elected this alternative option instead of the one described in the December 2018 rule. As a result, under the final rule, we delayed recognizing the estimated impact of CECL on regulatory capital until after a two-year deferral period, which for us extended through December 31, 2021. Beginning on January 1, 2022, we were required to phase in 25% of the previously deferred estimated capital impact of CECL, with an additional 25% to be phased in at the beginning of each subsequent year until fully phased in by the first quarter of 2025. The estimated impact of CECL on regulatory capital that we deferred and began phasing in on January 1, 2022, is generally calculated as the entire day-one impact at adoption plus 25% of the subsequent change in allowance during the two-year deferral period. As of March 31, 2022, the total deferred impact on Common Equity Tier 1 capital related to our adoption of CECL was $887 million. Capital Planning and Stress Tests Under the tailoring framework described earlier in the section titled Basel Capital Framework , we are generally subject to supervisory stress testing on a two-year cycle and exempted from mandated company-run capital stress testing requirements. We are also required to submit an annual capital plan to the FRB. Our annual capital plan must include an assessment of our expected uses and sources of capital and a description of all planned capital actions over a nine-quarter planning horizon, including any issuance of a debt or equity capital instrument, any dividend or other capital distribution, and any similar action that the FRB determines could have an impact on our capital. The plan must also include a detailed description of our process for assessing capital adequacy, including a discussion of how we, under expected and stressful conditions, will maintain capital commensurate with our risks and above the minimum regulatory capital ratios, will serve as a source of strength to Ally Bank, and will maintain sufficient capital to continue our operations by maintaining ready access to funding, meeting our obligations to creditors and other counterparties, and continuing to serve as a credit intermediary. In January 2021, the FRB issued a final rule effective April 5, 2021, to align its capital planning and stress capital buffer requirements with the tailoring framework. Under the final rule, unless otherwise directed by the FRB in specified circumstances, Ally and other Category IV firms are generally no longer required to calculate forward-looking projections of revenues, losses, reserves, and pro forma capital levels under scenarios provided by the FRB. Each firm continues to be required, however, to provide a forward-looking analysis of income and capital levels under expected and stressful conditions that are designed by the firm. In addition, for Category IV firms, the final rule updated the frequency of calculating the portion of the stress capital buffer derived from the supervisory stress test to every other year. These firms have the ability to elect to participate in the supervisory stress test—and receive a correspondingly updated stress capital buffer requirement—in a year in which they would not generally be subject to the supervisory stress test. During a year in which a Category IV firm does not undergo a supervisory stress test, the firm would receive an updated stress capital buffer requirement that reflects its updated planned common-stock dividends. The final rule also includes reporting and other changes consistent with the tailoring framework. Ally did not opt into the 2021 supervisory stress test but will be subject to the 2022 supervisory stress test. We submitted our 2021 capital plan on April 5, 2021, which included planned capital distributions to common stockholders through share repurchases and cash dividends and other capital actions over the nine-quarter planning horizon. On January 11, 2021, our Board authorized a stock-repurchase program, permitting us to repurchase up to $1.6 billion of our common stock from time to time from the first quarter of 2021 through the fourth quarter of 2021 subject to restrictions imposed by the FRB. On July 12, 2021, our Board authorized an increase in the maximum amount of this stock-repurchase program, from $1.6 billion to $2.0 billion. During the second quarter of 2021, we issued $1.35 billion of Series B Preferred Stock and $1.0 billion of Series C Preferred Stock, both of which qualify as additional Tier 1 capital under U.S. Basel III. The proceeds from these issuances were used to redeem a portion of the Series 2 TRUPS then outstanding. Refer to Note 15 for additional details about these instruments and capital actions. In June 2021, we submitted an updated capital plan to the FRB reflecting these capital actions and increases in our stock-repurchase program and common-stock dividend. This updated capital plan was used by the FRB to recalculate Ally’s final stress capital buffer requirement, which was announced in August 2021 and remained unchanged at 3.5%. We submitted our 2022 capital plan to the FRB on April 5, 2022. On January 10, 2022, our Board authorized a stock-repurchase program, permitting us to repurchase up to $2.0 billion of our common stock from time to time from the first quarter of 2022 through the fourth quarter of 2022 subject to restrictions imposed by the FRB, and an increase in our cash dividend on common stock from $0.25 per share for the fourth quarter of 2021 to $0.30 per share for the first quarter of 2022. Our ability to make capital distributions, including our ability to pay dividends or repurchase shares of our common stock, will continue to be subject to the FRB’s review and our internal governance requirements, including approval by our Board. The amount and size of any future dividends and share repurchases also will be subject to various factors, including Ally’s capital and liquidity positions, accounting and regulatory considerations (including any restrictions that may be imposed by the FRB), impacts related to the COVID-19 pandemic, financial and operational performance, alternative uses of capital, common-stock price, and general market conditions, and may be extended, modified, or discontinued at any time. The following table presents information related to our common stock and distributions to our common stockholders.

(b) Our aggregate common-stock dividends and share repurchases in the first and second quarters of 2021 were limited by actions taken by the FRB to address the economic uncertainty from the COVID-19 pandemic. Refer to Note 20 to the Consolidated Financial Statements in our 2021 Annual Report on Form 10-K for further details about these actions. (c) On April 13, 2022, our Board declared a quarterly cash dividend of $0.30 per share on all common stock, payable on May 16, 2022, to stockholders of record at the close of business on May 2, 2022. Refer to Note 25 for further information regarding this common-stock dividend.

Derivative Instruments and Hedg

Derivative Instruments and Hedging Activities	3 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging ActivitiesWe enter into derivative instruments, which may include interest rate swaps, foreign-currency forwards, equity options, and interest rate options in connection with our risk-management activities. Our primary objective for utilizing derivative financial instruments is to manage interest rate risk associated with our fixed-rate and variable-rate assets and liabilities, foreign exchange risks related to our foreign-currency denominated assets and liabilities, and other market risks related to our investment portfolio. Interest Rate Risk We monitor our mix of fixed-rate and variable-rate assets and liabilities and may enter into interest rate swaps, forwards, and options to achieve our desired mix of fixed-rate and variable-rate assets and liabilities. We execute these trades to modify our exposure to interest rate risk by converting certain fixed-rate instruments to a variable-rate and certain variable-rate instruments to a fixed-rate. We use a mix of both derivatives that qualify for hedge accounting treatment and economic hedges (which do not qualify for hedge accounting treatment). Derivatives qualifying for hedge accounting treatment can include receive-fixed swaps designated as fair value hedges of specific fixed-rate unsecured debt obligations, receive-fixed swaps designated as fair value hedges of specific fixed-rate FHLB advances, pay-fixed swaps designated as fair value hedges of securities within our available-for-sale portfolio, and pay-fixed swaps designated as fair value hedges of fixed-rate held-for-investment consumer automotive loan assets. Other derivatives qualifying for hedge accounting consist of pay-fixed swaps designated as cash flow hedges of the expected future cash flows in the form of interest payments on certain variable-rate borrowings and deposit liabilities, as well as interest rate floor contracts designated as cash flow hedges of the expected future cash flows in the form of interest receipts on a portion of our dealer floorplan commercial loans. We execute economic hedges, which may consist of interest rate swaps, interest rate caps, forwards, and options to mitigate interest rate risk. We also enter into interest rate lock commitments and forward commitments that are executed as part of our mortgage business that meet the accounting definition of a derivative. Foreign Exchange Risk We enter into derivative financial instrument contracts to mitigate the risk associated with variability in cash flows related to our various foreign-currency exposures. We enter into foreign-currency forwards with external counterparties as net investment hedges of foreign exchange exposure on our investment in foreign subsidiaries. Our equity is impacted by the cumulative translation adjustments resulting from the translation of foreign subsidiary results; this impact is reflected in our accumulated other comprehensive income. We also periodically enter into foreign-currency forwards to economically hedge any foreign-denominated debt, centralized lending, and foreign-denominated third-party loans. These foreign-currency forwards that are used as economic hedges are recorded at fair value with changes recorded as income or expense offsetting the gains and losses on the associated foreign-currency transactions. Investment Risk We enter into equity options to mitigate the risk associated with our exposure to the equity markets. Credit Risk We enter into various retail automotive-loan purchase agreements with certain counterparties. As part of those agreements, we may withhold a portion of the purchase price from the counterparty and be required to pay the counterparty all or part of the amount withheld at agreed upon measurement dates and determinable amounts if actual credit performance of the acquired loans on the measurement date is better than or equal to what was estimated at the time of acquisition. Based upon these terms, these contracts meet the accounting definition of a derivative. Counterparty Credit Risk Derivative financial instruments contain an element of credit risk if counterparties are unable to meet the terms of the agreements. Credit risk associated with derivative financial instruments is measured as the net replacement cost should the counterparties that owe us under the contract completely fail to perform under the terms of those contracts, assuming no recoveries of underlying collateral as measured by the market value of the derivative financial instrument. We manage our risk to financial counterparties through internal credit analysis, limits, and monitoring. Additionally, derivatives and repurchase agreements are entered into with approved counterparties using industry standard agreements. We execute certain OTC derivatives, such as interest rate caps and floors, using bilateral agreements with financial counterparties. Bilateral agreements generally require both parties to post collateral in the event the fair values of the derivative financial instruments meet posting thresholds established under the agreements. In the event that either party defaults on the obligation, the secured party may seize the collateral. Payments related to the exchange of collateral for OTC derivatives are recognized as collateral. We also execute certain derivatives, such as interest rate swaps, with clearinghouses, which requires us to post and receive collateral. For these clearinghouse derivatives, these payments are recognized as settlements rather than collateral. Certain derivative instruments contain provisions that require us to either post additional collateral or immediately settle any outstanding liability balances upon the occurrence of a specified credit-risk-related event. No such specified credit-risk-related events occurred during the three months ended March 31, 2022, or 2021. We placed cash and noncash collateral totaling $6 million and $260 million, respectively, supporting our derivative positions at March 31, 2022, compared to $2 million and $203 million of cash and noncash collateral at December 31, 2021, in accounts maintained by counterparties. These amounts include collateral placed at clearinghouses and exclude cash and noncash collateral pledged under repurchase agreements. The receivables for cash collateral placed are included on our Condensed Consolidated Balance Sheet in other assets. We received cash collateral from counterparties totaling $13 million and $4 million in accounts maintained by counterparties at March 31, 2022, and December 31, 2021, respectively. This amount includes collateral received from clearinghouses and exclude cash and noncash collateral pledged under repurchase agreements. The payables for cash collateral received are included on our Condensed Consolidated Balance Sheet in accrued expenses and other liabilities. Included in these amounts is noncash collateral where we have been granted the right to sell or pledge the underlying assets. We have not sold or pledged any of the noncash collateral received under these agreements. Balance Sheet Presentation The following table summarizes the amounts of derivative instruments reported on our Condensed Consolidated Balance Sheet. The amounts are presented on a gross basis, are segregated by derivatives that are designated and qualifying as hedging instruments or those that are not, and are further segregated by type of contract within those two categories. Derivative contracts in a receivable and payable position exclude open trade equity on derivatives cleared through central clearing counterparties. Any associated margin exchanged with our central clearing counterparties are treated as settlements of the derivative exposure, rather than collateral. Such payments are recognized as settlements of the derivatives contracts in a receivable and payable position on our Condensed Consolidated Balance Sheet. Notional amounts are reference amounts from which contractual obligations are derived and are not recorded on the balance sheet. In our view, derivative notional is not an accurate measure of our derivative exposure when viewed in isolation from other factors, such as market rate fluctuations and counterparty credit risk.

(b) These amounts include amortized cost basis of closed portfolios of available-for-sale securities used to designate hedging relationships in which the hedged item is the last layer expected to be remaining at the end of the hedging relationship. At March 31, 2022, and December 31, 2021, the amortized cost basis of the closed portfolios used in these hedging relationships was $4.1 billion and $3.9 billion, respectively. At March 31, 2022, and December 31, 2021, the total cumulative basis adjustments associated with these hedging relationships was a $44 million liability and a $6 million liability, respectively, of which the portion related to discontinued hedging relationships was a $54 million liability and a $20 million liability, respectively. At March 31, 2022, and December 31, 2021, the notional amounts of the designated hedged items were $2.0 billion and $1.2 billion, respectively, with cumulative basis adjustments of a $10 million asset and a $14 million asset, respectively, which would be allocated across the entire remaining closed pool upon termination or maturity of the hedge relationship. Refer to Note 7 for a reconciliation of the amortized cost and fair value of available-for-sale securities. (c) These amounts include the amortized cost basis of closed portfolios of loan receivables used to designate hedging relationships in which the hedged item is the last layer expected to be remaining at the end of the hedging relationship.

Income Taxes

Income Taxes	3 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We recognized total income tax expense from continuing operations of $191 million for the three months ended March 31, 2022, compared to income tax expense of $211 million for the same period in 2021. The decrease in income tax expense for the three months ended March 31, 2022, compared to the same period in 2021, was primarily due to the tax effects of a decrease in pretax earnings, partially offset by an increase of valuation allowance on foreign tax credit carryforwards. As of each reporting date, we consider existing evidence, both positive and negative, that could impact our view with regard to future realization of deferred tax assets. We continue to believe it is more likely than not that the benefit for certain foreign tax credit carryforwards and state net operating loss carryforwards will not be realized. In recognition of this risk, we continue to provide a partial valuation allowance on the deferred tax assets relating to these carryforwards and it is reasonably possible that the valuation allowance may change in the next 12 months.

Fair Value

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Fair Value Measurements For purposes of this disclosure, fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability (exit price) in the principal or most advantageous market in an orderly transaction between market participants at the measurement date under current market conditions. Fair value is based on the assumptions we believe market participants would use when pricing an asset or liability. Additionally, entities are required to consider all aspects of nonperformance risk, including the entity’s own credit standing, when measuring the fair value of a liability. GAAP specifies a three-level hierarchy that is used when measuring and disclosing fair value. The fair value hierarchy gives the highest priority to quoted prices available in active markets (i.e., observable inputs) and the lowest priority to data lacking transparency (i.e., unobservable inputs). An instrument’s categorization within the fair value hierarchy is based on the lowest level of significant input to its valuation. The following is a description of the three hierarchy levels. Level 1 Inputs are quoted prices in active markets for identical assets or liabilities at the measurement date. Additionally, the entity must have the ability to access the active market, and the quoted prices cannot be adjusted by the entity. Level 2 Inputs are other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices in active markets for similar assets or liabilities; quoted prices in inactive markets for identical or similar assets or liabilities; or inputs that are observable or can be corroborated by observable market data by correlation or other means for substantially the full term of the assets or liabilities. Level 3 Unobservable inputs are supported by little or no market activity. The unobservable inputs represent management’s best assumptions of how market participants would price the assets or liabilities. Generally, Level 3 assets and liabilities are valued using pricing models, discounted cash flow methodologies, or similar techniques that require significant judgment or estimation. Judgment is used in estimating inputs to our internal valuation models used to estimate our Level 3 fair value measurements. Level 3 inputs such as interest rate movements, prepayment speeds, credit losses, and discount rates are inherently difficult to estimate. Changes to these inputs can have a significant effect on fair value measurements and amounts that could be realized. The following are descriptions of the valuation methodologies used to measure material assets and liabilities at fair value and details of the valuation models, key inputs to those models, and significant assumptions utilized. • Equity securities — We hold various marketable equity securities measured at fair value with changes in fair value recognized in net income. Measurements based on observable market prices are classified as Level 1. • Available-for-sale securities — We carry our available-for-sale securities at fair value based on external pricing sources. We classify our securities as Level 1 when fair value is determined using quoted prices available for the same instruments trading in active markets. We classify our securities as Level 2 when fair value is determined using prices for similar instruments trading in active markets. We perform pricing validation procedures for our available-for-sale securities. • Derivative instruments — We enter into a variety of derivative financial instruments as part of our risk-management strategies. Certain of these derivatives are exchange traded, such as equity options. To determine the fair value of these instruments, we utilize the quoted market prices for those particular derivative contracts; therefore, we classified these contracts as Level 1. We also execute OTC and centrally cleared derivative contracts, such as interest rate swaps, foreign-currency denominated forward contracts, caps, floors, and agency to-be-announced securities. We utilize third-party-developed valuation models that are widely accepted in the market to value these derivative contracts. The specific terms of the contract and market observable inputs (such as interest rate forward curves, interpolated volatility assumptions, or equity pricing) are used in the model. We classified these derivative contracts as Level 2 because all significant inputs into these models were market observable. We also enter into interest rate lock commitments that are executed as part of our mortgage business, certain of which meet the accounting definition of a derivative and therefore are recorded as derivatives on our Condensed Consolidated Balance Sheet. Interest rate lock commitments are valued using internal pricing models with unobservable inputs, so they are classified as Level 3. We purchase automotive finance receivables and loans from third parties as part of forward flow arrangements and, from time-to-time, execute opportunistic ad-hoc bulk purchases. As part of those agreements, we may withhold a portion of the purchase price from the counterparty and be required to pay the counterparty all or part of the amount withheld at agreed upon measurement dates and determinable amounts if actual credit performance of the acquired loans on the measurement date is better than or equal to what was estimated at the time of acquisition. Because these contracts meet the accounting definition of a derivative, we recognize a liability at fair value for these deferred purchase price payments. The fair value of these liabilities is determined using a discounted cash flow method. To estimate cash flows, we utilize various significant assumptions, including market observable inputs (for example, forward interest rates) and internally developed inputs (for example, prepayment speeds, delinquency levels, and expected credit losses). These liabilities are valued using internal loss models with unobservable inputs, and are classified as Level 3. We are required to consider all aspects of nonperformance risk, including our own credit standing, when measuring fair value of a liability. We reduce credit risk on the majority of our derivatives by entering into legally enforceable agreements that enable the posting and receiving of collateral associated with the fair value of our derivative positions on an ongoing basis. In the event that we do not enter into legally enforceable agreements that enable the posting and receiving of collateral, we will consider our credit risk and the credit risk of our counterparties in the valuation of derivative instruments through a CVA, if warranted. The CVA calculation would utilize the credit default swap spreads of the counterparty. Recurring Fair Value The following tables display the assets and liabilities measured at fair value on a recurring basis including financial instruments elected for the fair value option. We often economically hedge the fair value change of our assets or liabilities with derivatives and other financial instruments. The tables below display the hedges separately from the hedged items; therefore, they do not directly display the impact of our risk-management activities.

Nonrecurring Fair Value We may be required to measure certain assets and liabilities at fair value from time to time. These periodic fair value measures typically result from the application of lower-of-cost or fair value accounting or certain impairment measures. These items would constitute nonrecurring fair value measures. The following tables display assets and liabilities measured at fair value on a nonrecurring basis and still held at March 31, 2022, and December 31, 2021, respectively. The amounts are generally as of the end of each period presented, which approximate the fair value measurements that occurred during each period.

The carrying values are inclusive of the respective valuation reserve, loan loss allowance, or cumulative adjustment. (b) Represents collateral-dependent loans held for investment for which a nonrecurring measurement was made. The related allowance for loan losses represents the cumulative fair value adjustments for those specific receivables.

Accordingly, the table above excludes total gains and losses included in earnings for these items. The carrying values are inclusive of the respective valuation reserve, loan loss allowance, or cumulative adjustment. (b) Represents collateral-dependent loans held for investment for which a nonrecurring measurement was made. The related allowance for loan losses represents the cumulative fair value adjustments for those specific receivables. (c) The allowance provided for repossessed and foreclosed assets represents any cumulative valuation adjustment recognized to adjust the assets to fair value. Fair Value Option for Financial Assets We elected the fair value option for an insignificant amount of conforming mortgage loans held-for-sale and certain acquired unsecured consumer finance receivables. We elected the fair value option for conforming mortgage loans held-for-sale to mitigate earnings volatility by better matching the accounting for the assets with the related derivatives. We elected the fair value option for certain acquired unsecured consumer finance receivables to mitigate the complexities of recording these loans at amortized cost. Our intent in electing fair value measurement was to mitigate a divergence between accounting gains or losses and economic exposure for certain assets and liabilities. Fair Value of Financial Instruments The following table presents the carrying and estimated fair value of financial instruments, except for those recorded at fair value on a recurring basis presented in the previous section of this note titled Recurring Fair Value. When possible, we use quoted market prices to determine fair value. Where quoted market prices are not available, the fair value is internally derived based on appropriate valuation methodologies with respect to the amount and timing of future cash flows and estimated discount rates. However, considerable judgment is required in interpreting current market data to develop the market assumptions and inputs necessary to estimate fair value. As such, the actual amount received to sell an asset or the amount paid to settle a liability could differ from our estimates. Fair value information presented herein was based on information available at March 31, 2022, and December 31, 2021. Estimated fair value ($ in millions) Carrying value Level 1 Level 2 Level 3 Total March 31, 2022 Financial assets Held-to-maturity securities $ 1,159 $ — $ 1,106 $ — $ 1,106 Loans held-for-sale, net 376 — — 376 376 Finance receivables and loans, net 122,057 — — 126,765 126,765 FHLB/FRB stock (a) 856 — 856 — 856 Financial liabilities Deposit liabilities $ 37,889 $ — $ — $ 37,793 $ 37,793 Short-term borrowings 3,950 — — 3,950 3,950 Long-term debt 15,885 — 10,991 6,514 17,505 December 31, 2021 Financial assets Held-to-maturity securities $ 1,170 $ — $ 1,204 $ — $ 1,204 Loans held-for-sale, net 469 — — 469 469 Finance receivables and loans, net 118,994 — — 126,044 126,044 FHLB/FRB stock (a) 738 — 738 — 738 Financial liabilities Deposit liabilities $ 40,953 $ — $ — $ 41,164 $ 41,164 Long-term debt 17,029 — 12,637 6,892 19,529 (a) Included in other assets on our Condensed Consolidated Balance Sheet. In addition to the financial instruments presented in the above table, we have various financial instruments for which the carrying value approximates the fair value due to their short-term nature and limited credit risk. These instruments include cash and cash equivalents, restricted cash, cash collateral, accrued interest receivable, accrued interest payable, trade receivables and payables, and other short-term receivables and payables. Included in cash and cash equivalents are highly liquid investments that are readily convertible to known amounts of cash and which are subject to an insignificant risk of change in value due to interest rate, quoted price, or penalty on withdrawal. Classified as Level 1 under the fair value hierarchy, cash and cash equivalents generally expose us to limited credit risk and are so near maturity that they present insignificant risk of changes in value because of changes in interest rates.

Offsetting [Abstract]
Offsetting Assets and Liabilities	Offsetting Assets and LiabilitiesOur derivative contracts and repurchase/reverse repurchase transactions are supported by qualifying master netting and master repurchase agreements. These agreements are legally enforceable bilateral agreements that (i) create a single legal obligation for all individual transactions covered by the agreement to the nondefaulting entity upon an event of default of the counterparty, including bankruptcy, insolvency, or similar proceeding, and (ii) provide the nondefaulting entity the right to accelerate, terminate, and close-out on a net basis all transactions under the agreement and to liquidate or set off collateral promptly upon an event of default of the counterparty. To further mitigate the risk of counterparty default related to derivative instruments, we maintain collateral agreements with certain counterparties. The agreements require both parties to maintain collateral in the event the fair values of the derivative financial instruments meet established thresholds. In the event that either party defaults on the obligation, the secured party may seize the collateral. Generally, our collateral arrangements are bilateral such that we and the counterparty post collateral for the obligation. Contractual terms provide for standard and customary exchange of collateral based on changes in the market value of the outstanding derivatives. A party posts additional collateral when their obligation rises or removes collateral when it falls, such that the net replacement cost of the nondefaulting party is covered in the event of counterparty default. In certain instances, as it relates to our derivative instruments, we have the option to report derivative assets and liabilities as well as assets and liabilities associated with cash collateral received or delivered that is governed by a master netting agreement on a net basis as long as certain qualifying criteria are met. Similarly, for our repurchase/reverse repurchase transactions, we have the option to report recognized assets and liabilities subject to a master netting agreement on a net basis if certain qualifying criteria are met. At March 31, 2022, these instruments are reported as gross assets and gross liabilities on the Condensed Consolidated Balance Sheet. For additional information on derivative instruments and hedging activities, refer to Note 19. The composition of offsetting derivative instruments, financial assets, and financial liabilities was as follows.

Segment Information

Segment Reporting [Abstract]
Segment Information	Segment Information Operating segments are defined as components of an enterprise that engage in business activity from which revenues are earned and expenses incurred for which discrete financial information is available that is evaluated regularly by our chief operating decision maker in deciding how to allocate resources and in assessing performance. We report our results of operations on a business-line basis through four operating segments: Automotive Finance operations, Insurance operations, Mortgage Finance operations, and Corporate Finance operations, with the remaining activity reported in Corporate and Other. The operating segments are determined based on the products and services offered, and reflect the manner in which financial information is currently evaluated by management. The following is a description of each of our reportable operating segments. Dealer Financial Services Dealer Financial Services comprises our Automotive Finance and Insurance segments. • Automotive Finance operations — One of the largest full-service automotive finance operations in the United States providing automotive financing services to consumers, automotive dealers, companies, and municipalities. Our automotive finance services include providing retail installment sales contracts, loans and operating leases, offering term loans to dealers, financing dealer floorplans and other lines of credit to dealers, warehouse lines to automotive retailers, fleet financing, providing financing to companies and municipalities for the purchase or lease of vehicles, and vehicle-remarketing services. • Insurance operations — A complementary automotive-focused business offering both consumer finance protection and insurance products sold primarily through the automotive dealer channel, and commercial insurance products sold directly to dealers. As part of our focus on offering dealers a broad range of consumer financial and insurance products, we provide VSCs, VMCs, and GAP products. We also underwrite select commercial insurance coverages, which primarily insure dealers’ vehicle inventory. Mortgage Finance operations Our held-for-investment portfolio includes our direct-to-consumer Ally Home mortgage offering and bulk purchases of high-quality jumbo and LMI mortgage loans originated by third parties. Through our direct-to-consumer channel, we offer a variety of competitively priced jumbo and conforming fixed- and adjustable-rate mortgage products through a third-party fulfillment provider. Through the bulk loan channel, we purchase loans from several qualified sellers on a servicing-released basis, allowing us to directly oversee servicing activities and manage refinancing through our direct-to-consumer channel. Corporate Finance operations Primarily provides senior secured leveraged cash flow and asset-based loans to mostly U.S.-based middle-market companies, with a focus on businesses owned by private equity sponsors. These loans are typically used for leveraged buyouts, refinancing and recapitalizations, mergers and acquisitions, growth, turnarounds, and debtor-in-possession financings. We also provide, through our Lender Finance business, nonbank wholesale-funded managers with partial funding for their direct-lending activities, which is principally leveraged loans. Additionally, we offer a commercial real estate product to serve companies in the healthcare industry. Corporate and Other primarily consists of centralized corporate treasury activities, such as management of the cash and corporate investment securities and loan portfolios, short- and long-term debt, retail and brokered deposit liabilities, derivative instruments, original issue discount, and the residual impacts of our corporate FTP and treasury ALM activities. Corporate and Other also includes certain equity investments, which primarily consist of FHLB and FRB stock—as well as other strategic investments—and the management of our legacy mortgage portfolio, which primarily consists of loans originated prior to January 1, 2009, and reclassifications and eliminations between the reportable operating segments. Financial results related to Ally Invest, our digital brokerage and wealth management offering, Ally Lending, our point-of-sale financing business, Ally Credit Card, and CRA loans and related investments are also included within Corporate and Other. We utilize an FTP methodology for the majority of our business operations. The FTP methodology assigns charge rates and credit rates to classes of assets and liabilities based on expected duration and the benchmark rate curve plus an assumed credit spread. Matching duration allocates interest income and interest expense to these reportable segments so their respective results are insulated from interest rate risk. This methodology is consistent with our ALM practices, which includes managing interest rate risk centrally at a corporate level. The net residual impact of the FTP methodology is included within the results of Corporate and Other. The information presented in our reportable operating segments is based in part on internal allocations, which involve management judgment. Financial information for our reportable operating segments is summarized as follows.

Contingencies and Other Risks	3 Months Ended

Loss Contingency [Abstract]
Contingencies and Other Risks	Contingencies and Other Risks As a financial-services company, we are regularly involved in pending or threatened legal proceedings and other matters and are or may be subject to potential liability in connection with them. These legal matters may be formal or informal and include litigation and arbitration with one or more identified claimants, certified or purported class actions with yet-to-be-identified claimants, and regulatory or other governmental information-gathering requests, examinations, investigations, and enforcement proceedings. Our legal matters exist in varying stages of adjudication, arbitration, negotiation, or investigation and span our business lines and operations. Claims may be based in law or equity—such as those arising under contracts or in tort and those involving banking, consumer-protection, securities, tax, employment, and other laws—and some can present novel legal theories and allege substantial or indeterminate damages. Ally and its subsidiaries, including Ally Bank, also are or may be subject to potential liability under other contingent exposures, including indemnification, tax, self-insurance, and other miscellaneous contingencies. We accrue for a legal matter or other contingent exposure when a loss becomes probable and the amount of loss can be reasonably estimated. Accruals are evaluated each quarter and may be adjusted, upward or downward, based on our best judgment after consultation with counsel. No assurance exists that our accruals will not need to be adjusted in the future. When a probable or reasonably possible loss on a legal matter or other contingent exposure could be material to our consolidated financial condition, results of operations, or cash flows, we provide disclosure in this note as prescribed by ASC Topic 450, Contingencies . Refer to Note 1 to the Consolidated Financial Statements in our 2021 Annual Report on Form 10-K for additional information related to our policy for establishing accruals. The course and outcome of legal matters are inherently unpredictable. This is especially so when a matter is still in its early stages, the damages sought are indeterminate or unsupported, significant facts are unclear or disputed, novel questions of law or other meaningful legal uncertainties exist, a request to certify a proceeding as a class action is outstanding or granted, multiple parties are named, or regulatory or other governmental entities are involved. Other contingent exposures and their ultimate resolution are similarly unpredictable for reasons that can vary based on the circumstances. As a result, we often are unable to determine how or when threatened or pending legal matters and other contingent exposures will be resolved and what losses may be incrementally and ultimately incurred. Actual losses may be higher or lower than any amounts accrued or estimated for those matters and other exposures, possibly to a significant degree. Subject to the foregoing, based on our current knowledge and after consultation with counsel, we do not believe that the ultimate outcomes of currently threatened or pending legal matters and other contingent exposures are likely to be material to our consolidated

Description of Business, Basi_2

Description of Business, Basis of Presentation, and Changes in Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2022
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Our accounting and reporting policies conform to U.S. GAAP. Additionally, where applicable, the policies conform to the accounting and reporting guidelines prescribed by bank regulatory authorities. Certain reclassifications may have been made to the prior periods’ financial statements and notes to conform to the current period’s presentation, which did not have a material impact on our Condensed Consolidated Financial Statements. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and that affect income and expenses during the reporting period and related disclosures. In developing the estimates and assumptions, management uses all available evidence; however, actual results could differ because of uncertainties associated with estimating the amounts, timing, and likelihood of possible outcomes. Our most significant estimates pertain to the allowance for loan losses, valuations of automotive lease assets and residuals, fair value of financial instruments, and the determination of the provision for income taxes.
Income Taxes	Income Taxes In calculating the provision for interim income taxes, in accordance with ASC 740, Income Taxes , we apply an estimated annual effective tax rate to year-to-date ordinary income. At the end of each interim period, we estimate the effective tax rate expected to be applicable for the full fiscal year. This method differs from that described in Note 1 to the Consolidated Financial Statements in our 2021 Annual Report on Form 10-K, which describes our annual significant income tax accounting policy and related methodology. Refer to Note 1 to the Consolidated Financial Statements in our 2021 Annual Report on Form 10-K regarding additional significant accounting policies.
Recently Issued Accounting Standards	Recently Issued Accounting Standards Fair Value Hedging—Portfolio Layer Method (ASU 2022-01) In March 2022, the FASB issued ASU 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method . The purpose of this guidance is to expand the current last-of-layer method to allow multiple hedged layers of a single closed portfolio. This change will allow hedge accounting to be achieved using different types of derivatives and layering techniques, including the use of amortizing swaps with clarification that such a trade would be viewed as being a single layer. Under this expanded scope, both prepayable and nonprepayable financial assets may be included in a single closed portfolio hedge. In addition, the guidance provides clarifications to breach requirements and disclosures. As a result of this change, the last-of-layer method has been renamed the portfolio layer method. The amendments are effective on January 1, 2023, with early adoption permitted. The amendments must be applied using a prospective approach and will not have a material impact upon adoption. Troubled Debt Restructurings and Vintage Disclosures (ASU 2022-02) In March 2022, the FASB issued ASU 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures . The purpose of this guidance is twofold. First, the guidance eliminates TDR recognition and measurement guidance that has been deemed no longer necessary under CECL. The guidance also adds a requirement to incorporate current year gross charge-offs by origination year into the vintage tables. With respect to the TDR impacts, under CECL, credit losses for financial assets measured at amortized cost are determined based on the total current expected credit losses over the life of the financial asset or group of financial assets. Therefore, credit losses on financial assets that have been modified as TDRs would have largely been incorporated in the allowance upon initial recognition. Under ASU 2022-02, we will be required to evaluate whether loan modifications previously characterized as TDRs represent a new loan or a continuation of an existing loan in accordance with ASC Topic 310, Receivables . The guidance also adds new disclosures that will require an entity to provide information related to loan modifications that are made to borrowers that are deemed to be in financial difficulty. The amendments are effective on January 1, 2023, with early adoption permitted. The amendments must be applied using a prospective approach; however, for the transition away from TDRs, the amendments may be adopted using a modified retrospective approach with a cumulative-effect adjustment through retained earnings as of the beginning of the fiscal year upon adoption. Management is currently evaluating the impact of these amendments.
Fair Value Measurements	Fair Value Measurements For purposes of this disclosure, fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability (exit price) in the principal or most advantageous market in an orderly transaction between market participants at the measurement date under current market conditions. Fair value is based on the assumptions we believe market participants would use when pricing an asset or liability. Additionally, entities are required to consider all aspects of nonperformance risk, including the entity’s own credit standing, when measuring the fair value of a liability. GAAP specifies a three-level hierarchy that is used when measuring and disclosing fair value. The fair value hierarchy gives the highest priority to quoted prices available in active markets (i.e., observable inputs) and the lowest priority to data lacking transparency (i.e., unobservable inputs). An instrument’s categorization within the fair value hierarchy is based on the lowest level of significant input to its valuation. The following is a description of the three hierarchy levels. Level 1 Inputs are quoted prices in active markets for identical assets or liabilities at the measurement date. Additionally, the entity must have the ability to access the active market, and the quoted prices cannot be adjusted by the entity. Level 2 Inputs are other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices in active markets for similar assets or liabilities; quoted prices in inactive markets for identical or similar assets or liabilities; or inputs that are observable or can be corroborated by observable market data by correlation or other means for substantially the full term of the assets or liabilities. Level 3 Unobservable inputs are supported by little or no market activity. The unobservable inputs represent management’s best assumptions of how market participants would price the assets or liabilities. Generally, Level 3 assets and liabilities are valued using pricing models, discounted cash flow methodologies, or similar techniques that require significant judgment or estimation. Judgment is used in estimating inputs to our internal valuation models used to estimate our Level 3 fair value measurements. Level 3 inputs such as interest rate movements, prepayment speeds, credit losses, and discount rates are inherently difficult to estimate. Changes to these inputs can have a significant effect on fair value measurements and amounts that could be realized.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Schedule of Derivative Instruments in Statement of Financial Position	The following table summarizes the amounts of derivative instruments reported on our Condensed Consolidated Balance Sheet. The amounts are presented on a gross basis, are segregated by derivatives that are designated and qualifying as hedging instruments or those that are not, and are further segregated by type of contract within those two categories. Derivative contracts in a receivable and payable position exclude open trade equity on derivatives cleared through central clearing counterparties. Any associated margin exchanged with our central clearing counterparties are treated as settlements of the derivative exposure, rather than collateral. Such payments are recognized as settlements of the derivatives contracts in a receivable and payable position on our Condensed Consolidated Balance Sheet. Notional amounts are reference amounts from which contractual obligations are derived and are not recorded on the balance sheet. In our view, derivative notional is not an accurate measure of our derivative exposure when viewed in isolation from other factors, such as market rate fluctuations and counterparty credit risk.

Fair Value, Assets Measured on a Recurring Basis, Unobservable Input Reconciliation	The following tables present the reconciliation for all Level 3 assets and liabilities measured at fair value on a recurring basis. We often economically hedge the fair value change of our assets or liabilities with derivatives and other financial instruments. The Level 3 items presented below may be hedged by derivatives and other financial instruments that are classified as Level 1 or Level 2.

Fair Value Measurements - Nonrecurring Basis	The following tables display assets and liabilities measured at fair value on a nonrecurring basis and still held at March 31, 2022, and December 31, 2021, respectively.

Fair Value, by Balance Sheet Grouping	The following table presents the carrying and estimated fair value of financial instruments, except for those recorded at fair value on a recurring basis presented in the previous section of this note titled Recurring Fair Value. When possible, we use quoted market prices to determine fair value. Where quoted market prices are not available, the fair value is internally derived based on appropriate valuation methodologies with respect to the amount and timing of future cash flows and estimated discount rates. However, considerable judgment is required in interpreting current market data to develop the market assumptions and inputs necessary to estimate fair value. As such, the actual amount received to sell an asset or the amount paid to settle a liability could differ from our estimates. Fair value information presented herein was based on information available at March 31, 2022, and December 31, 2021.
