Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying condensed consolidated financial statements were prepared in conformity with U.S. generally accepted accounting principles (“GAAP”). Preparing financial statements in conformity with U.S. GAAP requires us to make estimates based on assumptions about current, and for some estimates, future, economic and market conditions (for example, unemployment, housing, interest rates and market liquidity) which affect reported amounts and related disclosures in our condensed consolidated financial statements. Although our current estimates contemplate current conditions and how we expect them to change in the future, as appropriate, it is reasonably possible that actual conditions could be different than anticipated in those estimates, which could materially affect our results of operations and financial position. Among other effects, such changes could result in incremental losses on loan receivables, future impairments of debt securities, goodwill and intangible assets, increases in reserves for contingencies, establishment of valuation allowances on deferred tax assets and increases in our tax liabilities. We primarily conduct our business within the United States and substantially all of our revenues are from U.S. customers. The operating activities conducted by our non-U.S. affiliates use the local currency as their functional currency. The effects of translating the financial statements of these non-U.S. affiliates to U.S. dollars are included in equity. Asset and liability accounts are translated at period-end exchange rates, while revenues and expenses are translated at average rates for the respective periods. Consolidated Basis of Presentation The Company’s financial statements have been prepared on a consolidated basis. Under this basis of presentation, our financial statements consolidate all of our subsidiaries – i.e., entities in which we have a controlling financial interest, most often because we hold a majority voting interest. To determine if we hold a controlling financial interest in an entity, we first evaluate if we are required to apply the variable interest entity (“VIE”) model to the entity, otherwise the entity is evaluated under the voting interest model. We consolidate certain securitization entities under the VIE model. See Note 6. Variable Interest Entities . Interim Period Presentation The condensed consolidated financial statements and notes thereto are unaudited. These statements include all adjustments (consisting of normal recurring accruals) that we considered necessary to present a fair statement of our results of operations, financial position and cash flows. The results reported in these condensed consolidated financial statements should not be considered as necessarily indicative of results that may be expected for the entire year. These condensed consolidated financial statements should be read in conjunction with our 2023 annual consolidated financial statements and the related notes in our Annual Report on Form 10-K for the year ended December 31, 2023 (our "2023 Form 10-K"). New Accounting Standards Recently Issued But Not Yet Adopted Accounting Standards In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This ASU improves reportable segment disclosure requirements and requires enhanced disclosures about significant segment expenses. The Company will adopt this guidance on a retrospective basis on its effective date, which for us is beginning within our December 31, 2024 Form 10-K. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU requires disclosure of specific categories in the rate reconciliation, as well as additional qualitative information about the reconciliation, and additional disaggregated information about income taxes paid. The Company will adopt this guidance on a retrospective basis on its effective date, which for us is beginning within our December 31, 2025 Form 10-K. Equity Method Investments We use the equity method of accounting for investments where we have significant influence, but not control, over the operating and financial policies of the investee. Our assessment of significant influence includes factors such as our ownership interest, legal form, and representation on the board of directors. The Company generally records the initial investment at cost or fair value, as appropriate. Subsequently, we adjust each investment for our proportionate share of net income or loss in the investee. We amortize, where appropriate, differences between the Company’s cost basis and underlying equity in net assets, which are reported in Other Income. The Company evaluates equity method investments for other-than-temporary impairment when events or changes in circumstance indicate that the carrying amount of the investment might not be recoverable. See Note 2. Basis of Presentation and Summary of Significant Accounting Policies to our 2023 annual consolidated financial statements in our 2023 Form 10-K, for additional information on our other significant accounting policies.

Acquisitions and Dispositions

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
Acquisitions and Dispositions	ACQUISITIONS AND DISPOSITIONS Ally Lending On March 1, 2024, we acquired Ally Financial Inc.'s point of sale financing business, ("Ally Lending") for cash consideration of $2.0 billion. This acquisition deepens our presence and reach in the home improvement and health and wellness sectors, including high-growth specialty areas such as roofing, HVAC, and windows, as well as in cosmetic, audiology, and dentistry. The Ally Lending acquisition has been accounted for as a business combination using the acquisition method of accounting and, accordingly, assets acquired and liabilities assumed were recorded at their estimated fair value as of the acquisition date. There were no adjustments to the fair value of assets acquired and liabilities assumed (measurement period adjustments) related to the acquisition during the three months ended September 30, 2024. During the nine months ended September 30, 2024, measurement period adjustments were recognized related to the acquisition as detailed in the table below. ($ in millions) Amounts Recognized as of Acquisition Date (as previously reported as of March 31, 2024) Measurement Period Adjustments Amounts Recognized as of Acquisition Date (as adjusted) Assets acquired Cash $ 34 $ — $ 34 Loan receivables (a) 1,875 (198) 1,677 Intangible assets, net 23 (5) 18 Other assets 2 — 2 Total $ 1,934 $ (203) $ 1,731 Liabilities assumed Other liabilities (16) 2 (14) Total net identifiable assets acquired $ 1,918 $ (201) $ 1,717 Less: Total cash consideration paid $ 1,969 $ — $ 1,969 Goodwill $ 51 $ 201 $ 252 _______________________ (a) Loan discounts are recognized into interest income over the estimated remaining life of the acquired loans. The were no changes to the provisional amount of loan discount recorded in the three months ended September 30, 2024. The amounts above represent the estimated fair values of the respective assets acquired and liabilities assumed as of the date of acquisition. The estimated fair values reflect market participant assumptions about facts and circumstances existing at the acquisition date. The measurement period adjustments reflected above did not result from events occurring subsequent to the acquisition date. The valuation of the assets acquired and liabilities assumed is substantially complete and will be finalized no later than one year after the acquisition date. The goodwill recognized related to the acquisition is tax-deductible and reflects the expected synergies and operational efficiencies arising from the transaction. The acquisition primarily included loan receivables with an unpaid principal balance of $2.2 billion. These loan receivables are reported within Consumer installment loans in Note 5. Loan Receivables and Allowance for Credit Losses . To determine the provisional fair value of loans at acquisition, we estimate expected cash flows and discount those cash flows using an observable market rate of interest, when available, adjusted for factors that a market participant would consider in determining fair value. In determining fair value, expected cash flows are adjusted to include prepayment, default rate, and loss severity estimates. The difference between the fair value and the amount contractually due is recorded as a loan discount or premium at acquisition. Including the impact of measurement period adjustments, the provisional loan discount at the acquisition date was $469 million, which is to be amortized into interest income over the estimated remaining life of the loans, as described within Note 2. Basis of Presentation and Summary of Significant Accounting Policies within our 2023 Form 10-K. The interest and fees related to the acquired business are included in our Condensed Consolidated Statements of Earnings subsequent to the acquisition date and totaled $91 million and $232 million for the three and nine months ended September 30, 2024, respectively. These amounts include amortization of the loan discount recognized at acquisition of $42 million and $122 million, respectively. Expense activities, including those associated with the acquired business, are managed for the Company as a whole. Loans acquired without a more-than-insignificant credit deterioration since origination are measured under the Allowance for Credit Losses model, as described within Note 2. Basis of Presentation and Summary of Significant Accounting Policies within our 2023 Form 10-K. The Company’s best estimate of contractual cash flows not expected to be collected at the date of acquisition was $180 million, which is included within our allowance for credit losses, and recognized through provision for credit losses in our Condensed Consolidated Statements of Earnings for the nine months ended September 30, 2024. Included in the acquisition was $64 million of loans that have experienced more-than-insignificant deterioration in credit quality since origination (referred to as “purchased credit deteriorated” or “PCD” assets) that were not immediately written off at the acquisition date and are subject to specific guidance upon acquisition. An allowance for PCD assets of $39 million was recorded at the date of acquisition. Subsequent to initial recognition, the accounting for the PCD assets will generally follow the Allowance for Credit Losses model described within Note 2. Basis of Presentation and Summary of Significant Accounting Policies of our 2023 Form 10-K. Pets Best In March 2024, we sold our wholly-owned subsidiary, Pets Best Insurance Services, LLC (“Pets Best”) to Poodle Holdings, Inc. (“Buyer”) for consideration comprising a combination of cash and an equity interest of less than 10% in Independence Pet Holdings, Inc., ("IPH") an affiliate of Buyer. In connection with the sale, IPH also appointed two Synchrony executives to its board of directors. The sale of Pets Best resulted in the recognition of a gain on sale of $1.1 billion or $802 million, net of tax in the three months ended March 31, 2024. The pre-tax gain amount has been recognized within the Other component of Other Income in our Condensed Consolidated Statements of Earnings. The Company’s initial equity investment in IPH was recorded in Other Assets on our Condensed Consolidated Statements of Financial Position and is accounted for under the equity method of accounting. The investment was recorded at its estimated fair value at the date acquired of $605 million. The estimated fair value at acquisition date was determined using a weighted average methodology of three approaches: a market approach which includes using a multiple of projected revenues, precedent transactions and an intrinsic value analysis. The market-multiple approach was established based on a selected group of publicly traded companies. The use of selected precedent transaction multiples was calibrated to the valuation outcome using the market approach. Intrinsic value analysis determines implied multiples primarily based upon recent market studies and forecasted performance. The change in the carrying value of our equity investment in IPH subsequent to the date acquired was not material.

(b) Our asset-backed securities are collateralized by credit card and auto loans. (c) At September 30, 2024 and December 31, 2023, the estimated fair value of debt securities pledged by the Bank as collateral to the Federal Reserve to secure Federal Reserve discount window advances was $701 million and $360 million, respectively. The following table presents the estimated fair values and gross unrealized losses of our available-for-sale debt securities: In loss position for Less than 12 months 12 months or more Gross Gross Estimated unrealized Estimated unrealized ($ in millions) fair value losses fair value losses At September 30, 2024 U.S. government and federal agency $ — $ — $ — $ — State and municipal 5 — 4 — Residential mortgage-backed — — 305 (29) Asset-backed 43 — 136 (1) Other — — — — Total $ 48 $ — $ 445 $ (30) At December 31, 2023 U.S. government and federal agency $ 495 $ — $ 399 $ (1) State and municipal — — 9 — Residential mortgage-backed 1 — 346 (38) Asset-backed 171 — 244 (8) Other — — 8 — Total $ 667 $ — $ 1,006 $ (47) We regularly review debt securities for impairment resulting from credit loss using both qualitative and quantitative criteria, as necessary based on the composition of the portfolio at period end. Based on our assessment, no material impairments for credit losses were recognized during the period. We presently do not intend to sell our debt securities that are in an unrealized loss position and believe that it is not more likely than not that we will be required to sell these securities before recovery of our amortized cost. Contractual Maturities of Investments in Available-for-Sale Debt Securities Amortized Estimated Weighted At September 30, 2024 ($ in millions) cost fair value average yield (a) Due Within one year $ 1,272 $ 1,275 4.8 % After one year through five years $ 747 $ 755 5.0 % After five years through ten years $ 149 $ 141 1.8 % After ten years $ 194 $ 174 2.2 % _____________________ (a) Weighted average yield is calculated based on the amortized cost of each security. In calculating yield, no adjustment has been made with respect to any tax-exempt obligations. All securities are presented above based upon contractual maturity date, except our asset-backed securities which are allocated based upon expected final payment date. We expect actual maturities to differ from contractual maturities because borrowers have the right to prepay certain obligations. There were no material realized gains or losses recognized for the nine months ended September 30, 2024 and 2023.

(b) Excluded from the table above are allowance for credit losses for loan receivables acquired and immediately written off within the period presented. (c) Provision for credit losses in the Condensed Consolidated Statements of Earnings for the three and nine months ended September 30, 2024 also includes amounts associated with off-balance sheet credit exposures recorded in Accrued expenses and other liabilities in the Condensed Consolidated Statements of Financial Position. (d) Primarily represents allowance for credit losses for PCD assets. The reasonable and supportable forecast period used in our estimate of credit losses at September 30, 2024 was 12 months, consistent with the forecast period utilized since the adoption of CECL. Beyond the reasonable and supportable forecast period, we revert to historical loss information at the loan receivables segment level over a 6-month period, gradually increasing the weight of historical losses by an equal amount each month during the reversion period, and utilize historical loss information thereafter for the remaining life of the portfolio. The reversion period and methodology remain unchanged since the adoption of CECL. Losses on loan receivables, including those which are modified for borrowers experiencing financial difficulty, are estimated and recognized upon origination of the loan, based on expected credit losses for the life of the loan balance at September 30, 2024. Expected credit loss estimates are developed using both quantitative models and qualitative adjustments, and incorporates a macroeconomic forecast, as described within Note 2. Basis of Presentation and Summary of Significant Accounting Policies to our 2023 annual consolidated financial statements within our 2023 Form 10-K. The current and forecasted economic conditions at the balance sheet date influenced our current estimate of expected credit losses, which reflects our expectations of the macroeconomic environment. There have been no significant changes in our overall expectation of credit losses during the current quarterly period. We continued to experience a decrease in payment rates from the second quarter and have also experienced an increase in net charge-offs during the nine months ended September 30, 2024 as compared to the prior year period. These conditions are reflected in our current estimate of expected credit losses. Our allowance for credit losses increased to $11.0 billion during the nine months ended September 30, 2024, primarily reflecting these conditions and the impact of the Ally Lending acquisition. See Note 2. Basis of Presentation and Summary of Significant Accounting Policies to our 2023 annual consolidated financial statements within our 2023 Form 10-K for additional information on our significant accounting policies related to our allowance for credit losses.

Secured loan receivables are largely comprised of consumer installment loans secured by equipment. Unsecured loan receivables are largely comprised of our open-ended consumer and commercial revolving credit card loans. As part of our credit risk management activities, on an ongoing basis, we assess overall credit quality by reviewing information related to the performance of a customer’s account with us, including delinquency information, as well as information from credit bureaus relating to the customer’s broader credit performance. We utilize VantageScore credit scores to assist in our assessment of credit quality. VantageScore credit scores are obtained at origination of the account and are refreshed, at a minimum quarterly, but could be as often as weekly, to assist in predicting customer behavior. We categorize these credit scores into the following three credit score categories: (i) 651 or higher, which are considered the strongest credits; (ii) 591 to 650, considered moderate credit risk; and (iii) 590 or less, which are considered weaker credits. There are certain customer accounts, including for our commercial credit products, for which a VantageScore credit score may not be available where we use alternative sources to assess their credit quality and predict behavior. The following table provides the most recent VantageScore credit scores, or equivalent, available for our revolving credit card and commercial credit product customers at September 30, 2024, December 31, 2023 and September 30, 2023, respectively, as a percentage of each class of loan receivable. The table below excludes 0.3% of our total loan receivables balance for our credit cards and commercial credit products at each of September 30, 2024, December 31, 2023 and September 30, 2023, which represents those customer accounts for which a VantageScore credit score, or equivalent, is not available.

The new guidance is applicable for all loans modified to borrowers experiencing financial difficulties since January 1, 2023. See Note 2. Basis of Presentation and Summary of Significant Accounting Policies - Allowance for Credit Losses - Loan Modifications to Borrowers Experiencing Financial Difficulty within our 2023 Form 10-K for additional information on our significant accounting policies related to loan modifications to borrowers experiencing financial difficulty. The following table provides information on our loan modifications made to borrowers experiencing financial difficulty during the periods presented, which do not include loans that are classified as loan receivables held for sale: Three months ended September 30 2024 2023 ($ in millions) Amount (a) % of Total Class of Loan Receivables Amount % of Total Class of Loan Receivables Long-term modifications Credit cards $ 442 0.5 % $ 412 0.4 % Consumer installment loans — — % — — % Commercial credit products 3 0.2 % 1 0.1 % Short-term modifications Credit cards 231 0.2 % 163 0.2 % Consumer installment loans — — % — — % Commercial credit products — — % — — % Total $ 676 0.7 % $ 576 0.6 % Nine months ended September 30 2024 2023 ($ in millions) Amount (a) % of Total Class of Loan Receivables Amount % of Total Class of Loan Receivables Long-term modifications Credit cards $ 1,322 1.4 % $ 1,134 1.2 % Consumer installment loans — — % — — % Commercial credit products 7 0.4 % 4 0.2 % Short-term modifications Credit cards 704 0.7 % 440 0.5 % Consumer installment loans — — % — — % Commercial credit products 1 — % — — % Total $ 2,034 2.0 % $ 1,578 1.6 % _______________________ (a) Represents balance at enrollment date. Long-term and short-term loan modifications made to borrowers for the nine months ended September 30, 2024 had amortized cost balances at September 30, 2024 of $1.1 billion and $149 million, respectively. Financial Effects of Loan Modifications to Borrowers Experiencing Financial Difficulty As part of our loan modifications to borrowers experiencing financial difficulty, we may provide multiple concessions to minimize our economic loss and improve long-term loan performance and collectability. For long-term modifications made in the three and nine months ended September 30, 2024 and September 30, 2023, the financial effect of these modifications reduced the weighted-average interest rates by 97% for all periods presented. For short-term modifications made in the three months ended September 30 2024 and 2023, unpaid balances of $15 million and $10 million, respectively, were forgiven. For short-term modifications made in the nine months ended September 30, 2024 and 2023, unpaid balances of $216 million and $123 million, respectively, were forgiven. Additionally, beginning in the three months ended September 30, 2024, for borrowers that enroll in our short-term loan modification programs, we no longer charge interest and penalty fees during the term of the program. Performance of Loans Modified to Borrowers Experiencing Financial Difficulty The following tables provide information on the performance of loans modified to borrowers experiencing financial difficulty which have been modified within the previous 12 months and remain in a modification program at September 30, 2024.

Variable Interest Entities

Variable Interest Entities [Abstract]
Variable Interest Entities	VARIABLE INTEREST ENTITIES We use VIEs to securitize loan receivables and arrange asset-backed financing in the ordinary course of business. Investors in these entities only have recourse to the assets owned by the entity and not to our general credit. We do not have implicit support arrangements with any VIE and we did not provide non-contractual support for previously transferred loan receivables to any of these VIEs in the three and nine months ended September 30, 2024 and 2023. Our VIEs are able to accept new loan receivables and arrange new asset-backed financings, consistent with the requirements and limitations on such activities placed on the VIE by existing investors. Once an account has been designated to a VIE, the contractual arrangements we have require all existing and future loan receivables originated under such account to be transferred to the VIE. The amount of loan receivables held by our VIEs in excess of the minimum amount required under the asset-backed financing arrangements with investors may be removed by us under removal of accounts provisions. All loan receivables held by a VIE are subject to claims of third-party investors. In evaluating whether we have the power to direct the activities of a VIE that most significantly impact its economic performance, we consider the purpose for which the VIE was created, the importance of each of the activities in which it is engaged and our decision-making role, if any, in those activities that significantly determine the entity’s economic performance as compared to other economic interest holders. This evaluation requires consideration of all facts and circumstances relevant to decision-making that affects the entity’s future performance and the exercise of professional judgment in deciding which decision-making rights are most important. In determining whether we have the right to receive benefits or the obligation to absorb losses that could potentially be significant to a VIE, we evaluate all of our economic interests in the entity, regardless of form (debt, equity, management and servicing fees, and other contractual arrangements). This evaluation considers all relevant factors of the entity’s design, including: the entity’s capital structure, contractual rights to earnings or losses, subordination of our interests relative to those of other investors, as well as any other contractual arrangements that might exist that could have the potential to be economically significant. The evaluation of each of these factors in reaching a conclusion about the potential significance of our economic interests is a matter that requires the exercise of professional judgment. We consolidate VIEs where we have the power to direct the activities that significantly affect the VIEs' economic performance, typically because of our role as either servicer or administrator for the VIEs. The power to direct exists because of our role in the design and conduct of the servicing of the VIEs’ assets as well as directing certain affairs of the VIEs, including determining whether and on what terms debt of the VIEs will be issued. The loan receivables in these entities have risks and characteristics similar to our other loan receivables and were underwritten to the same standard. Accordingly, the performance of these assets has been similar to our other comparable loan receivables, and the blended performance of the pools of receivables in these entities reflects the eligibility criteria that we apply to determine which receivables are selected for transfer. Contractually, the cash flows from these loan receivables must first be used to pay third-party debt holders, as well as other expenses of the entity. Excess cash flows, if any, are available to us. The creditors of these entities have no claim on our other assets. The table below summarizes the assets and liabilities of our consolidated securitization VIEs described above: ($ in millions) September 30, 2024 December 31, 2023 Assets Loan receivables, net (a) $ 19,246 $ 19,537 Other assets (b) 47 47 Total $ 19,293 $ 19,584 Liabilities Borrowings $ 8,015 $ 7,267 Other liabilities 29 31 Total $ 8,044 $ 7,298 _______________________ (a) Includes $1.9 billion and $1.9 billion of related allowance for credit losses resulting in gross restricted loan receivables of $21.2 billion and $21.4 billion at September 30, 2024 and December 31, 2023, respectively. (b) Includes $42 million and $45 million of segregated funds held by the VIEs at September 30, 2024 and December 31, 2023, respectively, which are classified as restricted cash and equivalents and included as a component of Other assets The balances presented above are net of intercompany balances and transactions that are eliminated in our condensed consolidated financial statements. We provide servicing for all of our consolidated VIEs. Collections are required to be placed into segregated accounts owned by each VIE in amounts that meet contractually specified minimum levels. These segregated funds are invested in cash and cash equivalents and are restricted as to their use, principally to pay maturing principal and interest on debt and the related servicing fees. Collections above these minimum levels are remitted to us on a daily basis. Income (principally, interest and fees on loans) earned by our consolidated VIEs was $1.2 billion and $1.0 billion, for the three months ended September 30, 2024 and 2023, respectively. Related expenses consisted primarily of provision for credit losses of $331 million and $189 million, for the three months ended September 30, 2024 and 2023, respectively, and interest expense of $108 million and $86 million, for the three months ended September 30, 2024 and 2023, respectively. Income (principally, interest and fees on loans) earned by our consolidated VIEs was $3.2 billion and $2.9 billion, for the nine months ended September 30, 2024 and 2023, respectively. Related expenses consisted primarily of provision for credit losses of $753 million and $553 million, for the nine months ended September 30, 2024 and 2023, respectively, and interest expense of $323 million and $241 million, for the nine months ended September 30, 2024 and 2023, respectively. These amounts do not include intercompany transactions, principally fees and interest, which are eliminated in our condensed consolidated financial statements. Non-consolidated VIEs As part of our community reinvestment initiatives, we invest in funds that invest in affordable housing properties and receive affordable housing tax credits for these investments. These investments included in our Condensed Consolidated Statement of Financial Position totaled $755 million and $736 million at September 30, 2024 and December 31, 2023, respectively, and represents our total exposure for these entities. For the three months ended September 30, 2024 and 2023, provision for income taxes included amortization expense of $24 million and $21 million, respectively, and tax credits and other tax benefits of $30 million and $25 million, respectively, associated with investments in affordable housing properties. For the nine months ended September 30, 2024 and 2023, provision for income taxes included amortization expense of $71 million and $56 million, respectively, and tax credits and other tax benefits of $86 million and $72 million, respectively, associated with investments in affordable housing properties. Our other investments in non-consolidated VIEs, totaled $282 million and $252 million at September 30, 2024 and December 31, 2023, respectively. At September 30, 2024, the Company also had investment commitments of $197 million related to these investment s.

Regulatory and Capital Adequacy

Regulatory and Capital Adequacy	9 Months Ended
	Sep. 30, 2024
Banking Regulation, Risk-Based Information [Abstract]
Regulatory and Capital Adequacy	REGULATORY AND CAPITAL ADEQUACY As a savings and loan holding company and a financial holding company, we are subject to regulation, supervision and examination by the Federal Reserve Board and subject to the capital requirements as prescribed by Basel III capital rules and the requirements of the Dodd-Frank Wall Street Reform and Consumer Protection Act. The Bank is a federally chartered savings association. As such, the Bank is subject to regulation, supervision and examination by the Office of the Comptroller of the Currency of the U.S. Treasury (the “OCC”), which is its primary regulator, and by the Consumer Financial Protection Bureau (“CFPB”). In addition, the Bank, as an insured depository institution, is supervised by the FDIC. Failure to meet minimum capital requirements can initiate certain mandatory and, possibly, additional discretionary actions by regulators that, if undertaken, could limit our business activities and have a material adverse effect on our consolidated financial statements. Under capital adequacy guidelines, we must meet specific capital guidelines that involve quantitative measures of our assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Quantitative measures established by regulation to ensure capital adequacy require us and the Bank to maintain minimum amounts and ratios (set forth in the tables below) of Total, Tier 1 and common equity Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital to average assets (as defined). For Synchrony Financial to be a well-capitalized savings and loan holding company, the Bank must be well-capitalized and Synchrony Financial must not be subject to any written agreement, order, capital directive, or prompt corrective action directive issued by the Federal Reserve Board to meet and maintain a specific capital level for any capital measure. The Company elected to adopt the option provided by the interim final rule issued by joint federal bank regulatory agencies, which largely delayed the effects of CECL on its regulatory capital. Beginning in the first quarter of 2022, the effects are being phased-in over a three-year period through 2024 and will be fully phased-in beginning in the first quarter of 2025. Under the interim final rule, the amount of adjustments to regulatory capital deferred until the phase-in period included both the initial impact of our adoption of CECL at January 1, 2020 and 25% of subsequent changes in our allowance for credit losses during the two-year period ended December 31, 2021, collectively the “CECL regulatory capital transition adjustment”. Beginning in the first quarter of 2024 only 25% of the CECL regulatory capital transition adjustment is deferred in our regulatory capital amounts and ratios, as compared to 50% at December 31, 2023. At September 30, 2024 and December 31, 2023, Synchrony Financial met all applicable requirements to be deemed well-capitalized pursuant to Federal Reserve Board regulations. At September 30, 2024 and December 31, 2023, the Bank also met all applicable requirements to be deemed well-capitalized pursuant to OCC regulations and for purposes of the Federal Deposit Insurance Act.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE Basic earnings per share is computed by dividing earnings available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per common share reflects the assumed conversion of all dilutive securities, which are calculated using the treasury stock method. The following table presents the calculation of basic and diluted earnings per common share: Three months ended September 30, Nine months ended September 30, (in millions, except per share data) 2024 2023 2024 2023 Net earnings $ 789 $ 628 $ 2,725 $ 1,798 Preferred stock dividends (21) (10) $ (51) $ (31) Net earnings available to common stockholders $ 768 $ 618 $ 2,674 $ 1,767 Weighted average common shares outstanding, basic 392.3 416.0 398.7 $ 424.3 Effect of dilutive securities 4.2 2.4 3.7 $ 2.2 Weighted average common shares outstanding, dilutive 396.5 418.4 $ 402.4 $ 426.5 Earnings per basic common share $ 1.96 $ 1.49 $ 6.71 $ 4.16 Earnings per diluted common share $ 1.94 $ 1.48 $ 6.65 $ 4.14 We have issued certain stock-based awards under both the Synchrony Financial 2014 and 2024 Long-Term Incentive Plans. A total of zero shares and 3 million shares for the three months ended September 30, 2024 and 2023, respectively, and 1 million and 5 million shares for the nine months ended September 30, 2024 and 2023, respectively, related to these awards, were considered anti-dilutive and therefore were excluded from the computation of diluted earnings per common share.

(b) Comprised of federal unrecognized tax benefits and state and local unrecognized tax benefits net of the effects of associated U.S. federal income taxes. Excludes amounts attributable to any related valuation allowances resulting from associated increases in deferred tax assets. We establish a liability that represents the difference between a tax position taken (or expected to be taken) on an income tax return and the amount of taxes recognized in our financial statements. The liability associated with the unrecognized tax benefits is adjusted periodically when new information becomes available. The amount of unrecognized tax benefits that is reasonably possible to be resolved in the next twelve months is expected to be $35 million, of which $28 million, if recognized, would reduce the Company's tax expense and effective tax rate. In the current year, the Company executed a Memorandum of Understanding with the IRS to participate voluntarily in the IRS Compliance Assurance Process (“CAP”) program for the 2024 tax year, and thus the tax year is under IRS review. The IRS is also examining our 2023 tax year, and we expect the review will be completed in the current year. Additionally, we are under examination in various states going back to 2014. We believe that there are no issues or claims that are likely to significantly impact our results of operations, financial position or cash flows. We further believe that we have made adequate provision for all income tax uncertainties that could result from such examinations.

Legal Proceedings and Regulatory Matters	9 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Legal Proceedings and Regulatory Matters	LEGAL PROCEEDINGS AND REGULATORY MATTERS In the normal course of business, from time to time, we have been named as a defendant in various legal proceedings, including arbitrations, class actions and other litigation, arising in connection with our business activities. Certain of the legal actions include claims for substantial compensatory and/or punitive damages, or claims for indeterminate amounts of damages. We are also involved, from time to time, in reviews, investigations and proceedings (both formal and informal) by governmental agencies regarding our business (collectively, “regulatory matters”), which could subject us to significant fines, penalties, obligations to change our business practices or other requirements resulting in increased expenses, diminished income and damage to our reputation. We contest liability and/or the amount of damages as appropriate in each pending matter. In accordance with applicable accounting guidance, we establish an accrued liability for legal and regulatory matters when those matters present loss contingencies which are both probable and reasonably estimable. Legal proceedings and regulatory matters are subject to many uncertain factors that generally cannot be predicted with assurance, and we may be exposed to losses in excess of any amounts accrued. For some matters, we are able to determine that an estimated loss, while not probable, is reasonably possible. For other matters, including those that have not yet progressed through discovery and/or where important factual information and legal issues are unresolved, we are unable to make such an estimate. We currently estimate that the reasonably possible losses for legal proceedings and regulatory matters, whether in excess of a related accrued liability or where there is no accrued liability, and for which we are able to estimate a possible loss, are immaterial. This represents management’s estimate of possible loss with respect to these matters and is based on currently available information. This estimate of possible loss does not represent our potential maximum loss exposure. The legal proceedings and regulatory matters underlying the estimate will change from time to time and actual results may vary significantly from current estimates. Our estimate of reasonably possible losses involves significant judgment, given the varying stages of the proceedings, the existence of numerous yet to be resolved issues, the breadth of the claims (often spanning multiple years), unspecified damages and/or the novelty of the legal issues presented. Based on our current knowledge, we do not believe that we are a party to any pending legal proceeding or regulatory matters that would have a material adverse effect on our condensed consolidated financial condition or liquidity. However, in light of the uncertainties involved in such matters, the ultimate outcome of a particular matter could be material to our operating results for a particular period depending on, among other factors, the size of the loss or liability imposed and the level of our earnings for that period, and could adversely affect our business and reputation.

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2024
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements were prepared in conformity with U.S. generally accepted accounting principles (“GAAP”). Preparing financial statements in conformity with U.S. GAAP requires us to make estimates based on assumptions about current, and for some estimates, future, economic and market conditions (for example, unemployment, housing, interest rates and market liquidity) which affect reported amounts and related disclosures in our condensed consolidated financial statements. Although our current estimates contemplate current conditions and how we expect them to change in the future, as appropriate, it is reasonably possible that actual conditions could be different than anticipated in those estimates, which could materially affect our results of operations and financial position. Among other effects, such changes could result in incremental losses on loan receivables, future impairments of debt securities, goodwill and intangible assets, increases in reserves for contingencies, establishment of valuation allowances on deferred tax assets and increases in our tax liabilities. We primarily conduct our business within the United States and substantially all of our revenues are from U.S. customers. The operating activities conducted by our non-U.S. affiliates use the local currency as their functional currency. The effects of translating the financial statements of these non-U.S. affiliates to U.S. dollars are included in equity. Asset and liability accounts are translated at period-end exchange rates, while revenues and expenses are translated at average rates for the respective periods. Consolidated Basis of Presentation The Company’s financial statements have been prepared on a consolidated basis. Under this basis of presentation, our financial statements consolidate all of our subsidiaries – i.e., entities in which we have a controlling financial interest, most often because we hold a majority voting interest. To determine if we hold a controlling financial interest in an entity, we first evaluate if we are required to apply the variable interest entity (“VIE”) model to the entity, otherwise the entity is evaluated under the voting interest model. We consolidate certain securitization entities under the VIE model. See Note 6. Variable Interest Entities .
Interim Period Presentation	Interim Period Presentation The condensed consolidated financial statements and notes thereto are unaudited. These statements include all adjustments (consisting of normal recurring accruals) that we considered necessary to present a fair statement of our results of operations, financial position and cash flows. The results reported in these condensed consolidated financial statements should not be considered as necessarily indicative of results that may be expected for the entire year. These condensed consolidated financial statements should be read in conjunction with our 2023 annual consolidated financial statements and the related notes in our Annual Report on Form 10-K for the year ended December 31, 2023 (our "2023 Form 10-K").
New Accounting Standards	New Accounting Standards Recently Issued But Not Yet Adopted Accounting Standards In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This ASU improves reportable segment disclosure requirements and requires enhanced disclosures about significant segment expenses. The Company will adopt this guidance on a retrospective basis on its effective date, which for us is beginning within our December 31, 2024 Form 10-K. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU requires disclosure of specific categories in the rate reconciliation, as well as additional qualitative information about the reconciliation, and additional disaggregated information about income taxes paid. The Company will adopt this guidance on a retrospective basis on its effective date, which for us is beginning within our December 31, 2025 Form 10-K.
Equity Method Investments	Equity Method Investments We use the equity method of accounting for investments where we have significant influence, but not control, over the operating and financial policies of the investee. Our assessment of significant influence includes factors such as our ownership interest, legal form, and representation on the board of directors. The Company generally records the initial investment at cost or fair value, as appropriate. Subsequently, we adjust each investment for our proportionate share of net income or loss in the investee. We amortize, where appropriate, differences between the Company’s cost basis and underlying equity in net assets, which are reported in Other Income. The Company evaluates equity method investments for other-than-temporary impairment when events or changes in circumstance indicate that the carrying amount of the investment might not be recoverable.
