Organization, Consolidation and Presentation of Financial Statements [Abstract]
Introduction and Basis of Presentation	Introduction and Basis of Presentation The Charles Schwab Corporation (CSC) is a savings and loan holding company. Incorporated in 1986, CSC engages, through its subsidiaries, in wealth management, securities brokerage, banking, asset management, custody, and financial advisory services. Principal business subsidiaries of CSC include the following: • Charles Schwab & Co., Inc. (CS&Co), incorporated in 1971, a securities broker-dealer; • TD Ameritrade, Inc., an introducing securities broker-dealer; • TD Ameritrade Clearing, Inc. (TDAC), a securities broker-dealer that provides trade execution and clearing services to TD Ameritrade, Inc.; • Charles Schwab Bank, SSB (CSB), our principal banking entity; and • Charles Schwab Investment Management, Inc. (CSIM), the investment advisor for Schwab’s proprietary mutual funds (Schwab Funds ® ) and for Schwab’s exchange-traded funds (Schwab ETFs ™ ). Unless otherwise indicated, the terms “Schwab,” “the Company,” “we,” “us,” or “our” mean CSC together with its consolidated subsidiaries. These unaudited condensed consolidated financial statements have been prepared in conformity with GAAP, which require management to make certain estimates and assumptions that affect the reported amounts in the accompanying financial statements and in the related disclosures. These estimates are based on information available as of the date of the condensed consolidated financial statements. While management makes its best judgment, actual amounts or results could differ from these estimates. In the opinion of management, all normal, recurring adjustments have been included for a fair statement of this interim financial information. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto, included in Schwab’s 2020 Form 10-K. Effective October 6, 2020, the Company completed its acquisition of TD Ameritrade Holding Corporation and its consolidated subsidiaries (collectively referred to as “TD Ameritrade” or “TDA”). TD Ameritrade provides securities brokerage services, including trade execution, clearing services, and margin lending, through its broker-dealer subsidiaries; and futures and foreign exchange trade execution services through its futures commission merchant (FCM) and forex dealer member (FDM) subsidiary. Our consolidated financial statements include the results of operations and financial condition of TD Ameritrade beginning on October 6, 2020. See Note 3 for additional information on our acquisition of TD Ameritrade. Reclassifications: Certain prior period amounts have been reclassified to conform to the current period presentation. Beginning in the third quarter of 2020, amortization of acquired intangible assets was reclassified from depreciation and amortization and presented separately in the condensed consolidated statements of income. Prior period amounts have been reclassified to reflect this change. A corresponding presentation change has been made to the condensed consolidated statements of cash flows. The significant accounting policies are included in Note 2 in the 2020 Form 10-K. There have been no significant changes to these accounting policies during the first six months of 2021.

Business Combinations [Abstract]
Business Acquisitions	Business Acquisitions TD Ameritrade On October 6, 2020, Schwab completed its previously announced acquisition of TD Ameritrade for $21.8 billion in stock. As a result of the acquisition, TDA Holding became a wholly-owned subsidiary of CSC. In exchange for each share of TD Ameritrade common stock, TD Ameritrade stockholders received 1.0837 shares of CSC common stock, except for TD Bank and its affiliates which received a portion in nonvoting common stock. In connection with the transaction, Schwab issued approximately 586 million common shares to TD Ameritrade stockholders consisting of approximately 509 million shares of common stock and approximately 77 million shares of nonvoting common stock. Subsequently, TD Bank and its affiliates exchanged common stock for nonvoting common stock and held approximately 79 million shares of nonvoting common stock as of June 30, 2021. For further details on the new class of nonvoting common stock, see Note 19 in the 2020 Form 10-K. There have been no adjustments to the provisional purchase price and fair value estimates presented in Note 3 of the 2020 Form 10-K, and such amounts are now final with the exception of estimates related to certain acquired assets classified as other assets and certain assumed liabilities classified as accrued expenses and other liabilities within the Company’s condensed consolidated balance sheet. These estimates are considered provisional and are based on currently available information. The Company believes that the information available provides a reasonable basis for estimating the fair values of such assets acquired and liabilities assumed; however, these provisional estimates may be adjusted upon the availability of new information regarding facts and circumstances which existed at the acquisition date. The Company expects to finalize the valuation of these assets and liabilities as soon as practicable, but not later than one year from the acquisition date. Any adjustments to the initial estimates of the fair values of the acquired assets and assumed liabilities will be recorded as adjustments to the respective assets and liabilities, with the residual amounts allocated to goodwill.

At June 30, 2021, our banking subsidiaries had pledged securities with a fair value of $43.6 billion as collateral to secure borrowing capacity on secured credit facilities with the Federal Home Loan Bank (FHLB) (see Note 9). Our banking subsidiaries also pledge investment securities as collateral to secure borrowing capacity at the Federal Reserve discount window, and had pledged securities with a fair value of $9.5 billion as collateral for this facility at June 30, 2021. The Company also pledges securities issued by federal agencies to secure certain trust deposits. The fair value of these pledged securities was $1.5 billion at June 30, 2021.

U.S. agency mortgage-backed securities do not have explicit credit ratings; however, management considers these to be of the highest credit quality and rating given the guarantee of principal and interest by the U.S. government or U.S. government-sponsored enterprises. For a description of management’s quarterly evaluation of AFS securities in unrealized loss positions see Item 8 – Note 2 in the 2020 Form 10-K. No amounts were recognized as credit loss expense and no securities were written down to fair value through earnings for the six months ended June 30, 2021 and the year ended December 31, 2020. None of the Company’s AFS securities held as of June 30, 2021 and December 31, 2020 had an allowance for credit losses. The Company had $635 million and $634 million of accrued interest receivable as of June 30, 2021 and December 31, 2020, respectively, for AFS securities. These amounts are excluded from the amortized cost basis and fair market value of AFS securities and included in other assets on the condensed consolidated balance sheets. There were no write-offs of accrued interest receivable on AFS securities during the six months ended June 30, 2021, or the year ended December 31, 2020.

(2) At June 30, 2021 and December 31, 2020, 46% and 45%, respectively, of the First Mortgage and HELOC portfolios were concentrated in California. These loans have performed in a manner consistent with the portfolio as a whole. (3) There were no loans accruing interest that were contractually 90 days or more past due at June 30, 2021 or December 31, 2020. At June 30, 2021, CSB had pledged the full balance of First Mortgages and HELOCs pursuant to a blanket lien status collateral arrangement to secure borrowing capacity on a secured credit facility with the FHLB (see Note 9).

All PALs were fully collateralized by securities with fair values in excess of borrowings as of June 30, 2021 and December 31, 2020. Therefore, no allowance for credit losses for PALs as of those dates was required. The economy continues to improve as vaccinations appear to limit the spread of COVID-19 in the United States, though some risks to the economy remain. Management’s macroeconomic outlook reflects continued growth in home prices and lower unemployment anticipated over the near term. This macroeconomic outlook, along with the continued strong credit quality metrics in the bank loans portfolio, result in a lower modeled projection of loss rates compared to December 31, 2020. A summary of bank loan-related nonperforming assets and troubled debt restructurings is as follows: June 30, 2021 December 31, 2020 Nonaccrual loans (1) $ 53 $ 89 Other real estate owned (2) 1 1 Total nonperforming assets 54 90 Troubled debt restructurings — 1 Total nonperforming assets and troubled debt restructurings $ 54 $ 91 (1) Nonaccrual loans include nonaccrual troubled debt restructurings. (2) Included in other assets on the condensed consolidated balance sheets. Credit Quality In addition to monitoring delinquency, Schwab monitors the credit quality of First Mortgages and HELOCs by stratifying the portfolios by the following: • Year of origination; • Borrower FICO scores at origination (Origination FICO); • Updated borrower FICO scores (Updated FICO); • Loan-to-value (LTV) ratios at origination (Origination LTV); and • Estimated current LTV ratios (Estimated Current LTV). Borrowers’ FICO scores are provided by an independent third-party credit reporting service and generally updated quarterly. The Origination LTV and Estimated Current LTV for a HELOC include any first lien mortgage outstanding on the same property at the time of the HELOC’s origination. The Estimated Current LTV for each loan is updated on a monthly basis by reference to a home price appreciation index. The credit quality indicators of the Company’s bank loan portfolio are detailed below: First Mortgages Amortized Cost Basis by Origination Year June 30, 2021 2021 2020 2019 2018 2017 pre-2017 Total First Mortgages Revolving HELOCs amortized cost basis HELOCs converted to term loans Total HELOCs Origination FICO <620 $ — $ 1 $ — $ — $ — $ 1 $ 2 $ — $ — $ — 620 – 679 15 29 7 1 8 22 82 — 3 3 680 – 739 660 678 228 60 124 300 2,050 70 68 138 ≥740 5,774 5,919 1,563 274 533 1,381 15,444 333 252 585 Total $ 6,449 $ 6,627 $ 1,798 $ 335 $ 665 $ 1,704 $ 17,578 $ 403 $ 323 $ 726 Origination LTV ≤70% $ 5,556 $ 5,524 $ 1,409 $ 245 $ 507 $ 1,291 $ 14,532 $ 321 $ 229 $ 550 >70% – ≤90% 893 1,103 389 90 158 410 3,043 82 91 173 >90% – ≤100% — — — — — 3 3 — 3 3 Total $ 6,449 $ 6,627 $ 1,798 $ 335 $ 665 $ 1,704 $ 17,578 $ 403 $ 323 $ 726 Weighted Average <620 $ 6 $ 3 $ 3 $ 1 $ 4 $ 16 $ 33 $ 3 $ 7 $ 10 620 – 679 49 78 27 8 13 45 220 10 16 26 680 – 739 630 524 172 40 80 207 1,653 50 46 96 ≥740 5,764 6,022 1,596 286 568 1,436 15,672 340 254 594 Total $ 6,449 $ 6,627 $ 1,798 $ 335 $ 665 $ 1,704 $ 17,578 $ 403 $ 323 $ 726 Estimated Current LTV (1) ≤70% $ 5,731 $ 6,388 $ 1,768 $ 331 $ 658 $ 1,698 $ 16,574 $ 400 $ 319 $ 719 >70% – ≤90% 718 239 30 4 7 6 1,004 3 4 7 >90% – ≤100% — — — — — — — — — — >100% — — — — — — — — — — Total $ 6,449 $ 6,627 $ 1,798 $ 335 $ 665 $ 1,704 $ 17,578 $ 403 $ 323 $ 726 Percent of Loans on 0.03 % 0.09 % 0.14 % 0.65 % 0.51 % 1.38 % 0.22 % 1.38 % 2.55 % 1.93 % (1) Represents the LTV for the full line of credit (drawn and undrawn) for revolving HELOCs.

At June 30, 2021, First Mortgage loans of $14.6 billion had adjustable interest rates. Substantially all of these mortgages have initial fixed interest rates for three three At June 30, 2021 and December 31, 2020, Schwab had $50 million and $43 million, respectively, of accrued interest on bank loans, which is excluded from the amortized cost basis of bank loans and included in other assets on the condensed consolidated balance sheets. The HELOC product has a 30-year loan term with an initial draw period of ten years from the date of origination. After the initial draw period, the balance outstanding at such time is converted to a 20-year amortizing loan. The interest rate during the initial draw period and the 20-year amortizing period is a floating rate based on the prime rate plus a margin. The following table presents HELOCs converted to amortizing loans during each period presented: Three Months Ended Six Months Ended 2021 2020 2021 2020 HELOCs converted to amortizing loans $ 7 $ 8 $ 14 $ 18 The following table presents when current outstanding HELOCs will convert to amortizing loans: June 30, 2021 Balance Converted to an amortizing loan by period end $ 323 Within 1 year 16 > 1 year – 3 years 82 > 3 years – 5 years 76 > 5 years 229 Total $ 726 At June 30, 2021, $563 million of the HELOC portfolio was secured by second liens on the associated properties. Second lien mortgage loans typically possess a higher degree of credit risk given the subordination to the first lien holder in the event of default. In addition to the credit monitoring activities described previously, Schwab also monitors credit risk by reviewing the delinquency status of the first lien loan on the associated property. At June 30, 2021, the borrowers on approximately 52% of HELOC loan balances outstanding only paid the minimum amount due.

Variable Interest Entities [Abstract]
Variable Interest Entities	Variable Interest Entities As of June 30, 2021 and December 31, 2020, all of Schwab’s involvement with variable interest entities (VIEs) is through CSB’s Community Reinvestment Act (CRA)-related investments and most of those are related to LIHTC investments. As part of CSB’s community reinvestment initiatives, CSB invests in funds that make equity investments in multifamily affordable housing properties and receives tax credits and other tax benefits for these investments. Aggregate assets, liabilities and maximum exposure to loss The aggregate assets, liabilities, and maximum exposure to loss from those VIEs in which Schwab holds a variable interest, but is not the primary beneficiary, are summarized in the table below: June 30, 2021 December 31, 2020 Aggregate Aggregate Maximum Aggregate Aggregate Maximum LIHTC investments (1) $ 785 $ 461 $ 785 $ 649 $ 344 $ 649 Other CRA investments (2) 136 — 154 118 — 152 Total $ 921 $ 461 $ 939 $ 767 $ 344 $ 801 (1) Aggregate assets and aggregate liabilities are included in other assets and accrued expenses and other liabilities, respectively, on the condensed consolidated balance sheets. (2) Other CRA investments are accounted for as loans at amortized cost, equity method investments, AFS securities, or using the adjusted cost method. Aggregate assets are included in AFS securities, bank loans – net, or other assets on the condensed consolidated balance sheets. Schwab’s maximum exposure to loss would result from the loss of the investments, including any committed amounts. CSB’s funding of these remaining commitments is dependent upon the occurrence of certain conditions, and CSB expects to pay substantially all of these commitments between 2021 and 2024.

The investment in FHLB was $29 million at June 30, 2021 and December 31, 2020. Additionally, our banking subsidiaries have access to funding through the Federal Reserve discount window. Amounts available are dependent upon the fair value of certain investment securities that are pledged as collateral. As of June 30, 2021 and December 31, 2020, the collateral pledged provided total borrowing capacity of $9.5 billion and $7.9 billion, respectively, of which no amounts were outstanding at the end of either period. CSC has the ability to issue commercial paper notes with maturities up to 270 days, and had $1.5 billion outstanding at June 30, 2021 and none at December 31, 2020. CSB and Charles Schwab Premier Bank, SSB (CSPB) are members of the Federal Reserve. As a condition of our Federal Reserve membership, we are required to hold Federal Reserve stock, which totaled $310 million and $191 million at June 30, 2021 and December 31, 2020, respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Loan Portfolio: CSB provides a co-branded loan origination program for CSB clients (the Program) with Rocket Mortgage, LLC (Rocket Mortgage ® ), formerly known as Quicken Loans, LLC. Pursuant to the Program, Rocket Mortgage originates and services First Mortgages and HELOCs for CSB clients. Under the Program, CSB purchases certain First Mortgages and HELOCs that are originated by Rocket Mortgage. CSB purchased First Mortgages of $4.0 billion and $2.7 billion during the second quarters of 2021 and 2020, respectively, and $6.8 billion and $4.9 billion during the first six months of 2021 and 2020, respectively. CSB purchased HELOCs with commitments of $114 million and $133 million during the second quarters of 2021 and 2020, respectively, and $213 million and $240 million during the first six months of 2021 and 2020, respectively. The Company’s commitments to extend credit on bank lines of credit and to purchase First Mortgages are as follows: June 30, 2021 December 31, 2020 Commitments to extend credit related to unused HELOCs, PALs, and other lines of credit $ 7,127 $ 8,141 Commitments to purchase First Mortgage loans 2,575 1,917 Total $ 9,702 $ 10,058 Guarantees and indemnifications: Schwab has clients that sell (i.e., write) listed option contracts that are cleared by the Options Clearing Corporation – a clearing house that establishes margin requirements on these transactions. We partially satisfy the margin requirements by arranging unsecured standby letter of credit agreements (LOCs), in favor of the Options Clearing Corporation, which are issued by several banks. At June 30, 2021, the aggregate face amount of these LOCs totaled $15 million. There were no funds drawn under any of these LOCs at June 30, 2021. In connection with its securities lending activities, Schwab is required to provide collateral to certain brokerage clients. The Company satisfies the collateral requirements by providing cash as collateral. The Company also provides guarantees to securities clearing houses and exchanges under standard membership agreements, which require members to guarantee the performance of other members. Under the agreements, if another member becomes unable to satisfy its obligations to the clearing houses and exchanges, other members would be required to meet shortfalls. The Company’s liability under these arrangements is not quantifiable and may exceed the amounts it has posted as collateral. The potential requirement for the Company to make payments under these arrangements is remote. Accordingly, no liability has been recognized for these guarantees. The TD Ameritrade broker-dealer and FCM/FDM subsidiaries’ operations include the execution, settlement, and financing of various client securities, options, futures and foreign exchange transactions. These activities may expose the Company to credit risk and losses in the event the clients are unable to fulfill their contractual obligations. TD Ameritrade is a member of and provides guarantees to securities clearing houses and exchanges under standard membership agreements. TD Ameritrade also engages third-party firms to clear clients’ futures and options on futures transactions and to facilitate clients’ foreign exchange trading, and has agreed to indemnify these firms for any loss that they may incur from the client transactions introduced to them by TD Ameritrade. The potential requirement for the Company to make payments under these arrangements is remote. Accordingly, no liability has been recognized for these guarantees. IDA agreement: The Company’s IDA agreement with the TD Depository Institutions became effective on October 6, 2020. The IDA agreement creates responsibilities of the Company and certain contingent obligations. Pursuant to the IDA agreement, cash held in eligible brokerage client accounts must be swept off-balance sheet to money market deposit accounts at the TD Depository Institutions. Schwab provides marketing, recordkeeping and support services to the TD Depository Institutions with respect to the money market deposit accounts for which Schwab receives an aggregate monthly fee, determined by reference to certain yields, less a service fee on client cash deposits held at the TD Depository Institutions, FDIC insurance assessments, and interest on deposits paid to clients. Though unlikely, in the event the sweep arrangement fee computation were to result in a negative amount in any given month, Schwab would be required to pay the TD Depository Institutions. Pursuant to the IDA agreement, Schwab moved $8.7 billion of uninsured IDA balances out of the IDA sweep program in July 2021. The IDA agreement also provides that, starting July 1, 2021, Schwab has the option to migrate up to $10 billion of IDA balances every 12 months to Schwab’s balance sheet, subject to certain limitations and adjustments. Inclusive of the uninsured balances and transfers relating to certain international accounts, IDA balances moved to Schwab’s balance sheet totaled $9.9 billion through July 31, 2021. The Company’s ability to migrate IDA balances to its balance sheet is dependent upon multiple factors including having sufficient capital levels to sustain these incremental deposits and certain binding limitations specified in the IDA agreement, including the requirement that Schwab can only move IDA balances designated as floating-rate obligations. In addition, Schwab also must maintain a minimum $50 billion IDA balance through June 2031, and at least 80% of the IDA balances must be designated as fixed-rate obligations through June 2026. The total ending IDA balance was $150.0 billion as of June 30, 2021, $154.1 billion as of December 31, 2020, and $144.6 billion as of October 5, 2020. If IDA balances were to decline below the required IDA balance minimum, Schwab could be required to direct additional sweep cash from its balance sheet to the IDA program. Legal contingencies: Schwab is subject to claims and lawsuits in the ordinary course of business, including arbitrations, class actions and other litigation, some of which include claims for substantial or unspecified damages. The Company is also the subject of inquiries, investigations, and proceedings by regulatory and other governmental agencies. Predicting the outcome of a litigation or regulatory matter is inherently difficult, requiring significant judgment and evaluation of various factors, including the procedural status of the matter and any recent developments; prior experience and the experience of others in similar cases; available defenses, including potential opportunities to dispose of a case on the merits or procedural grounds before trial (e.g., motions to dismiss or for summary judgment); the progress of fact discovery; the opinions of counsel and experts regarding potential damages; and potential opportunities for settlement and the status of any settlement discussions. It may not be reasonably possible to estimate a range of potential liability until the matter is closer to resolution – pending, for example, further proceedings, the outcome of key motions or appeals, or discussions among the parties. Numerous issues may have to be developed, such as discovery of important factual matters and determination of threshold legal issues, which may include novel or unsettled questions of law. Reserves are established or adjusted or further disclosure and estimates of potential loss are provided as the matter progresses and more information becomes available. Schwab believes it has strong defenses in all significant matters currently pending and is contesting liability and any damages claimed. Nevertheless, some of these matters may result in adverse judgments or awards, including penalties, injunctions or other relief, and the Company may also determine to settle a matter because of the uncertainty and risks of litigation. Described below are matters in which there is a reasonable possibility that a material loss could be incurred or where the matter may otherwise be of significant interest to stockholders. Unless otherwise noted, the Company is unable to provide a reasonable estimate of any potential liability given the stage of proceedings in the matter. With respect to all other pending matters, based on current information and consultation with counsel, it does not appear reasonably possible that the outcome of any such matter would be material to the financial condition, operating results, or cash flows of the Company. Schwab Intelligent Portfolios ® SEC Investigation : As disclosed on July 1, 2021, the Company has been responding to an enforcement investigation by the SEC arising from a compliance examination and concerning historic disclosures related to the Schwab Intelligent Portfolios digital advisory solution. In connection with a tentative agreement reached with SEC staff to resolve the matter, second quarter 2021 financial results included a liability and related non-deductible charge of $200 million. Completion of any settlement is always contingent on a vote of the Commission. The Company continues to cooperate with SEC staff with the goal of fully resolving the matter. TD Ameritrade Acquisition Litigation : As disclosed previously, Schwab and TD Ameritrade have been responding to a lawsuit challenging the acquisition which was filed on May 12, 2020 in the Delaware Court of Chancery (Hawkes v. Bettino et al.) on behalf of a proposed class of TD Ameritrade’s stockholders, excluding, among others, TD Bank. The initial complaint named as defendants each member of the TD Ameritrade board of directors at the time the acquisition was approved, as well as TD Bank and Schwab. On June 11, 2020, plaintiff dismissed a claim that had sought to enjoin voting on or consummation of the acquisition. On February 5, 2021, plaintiff filed an amended complaint naming an officer and certain directors of TD Ameritrade at the time the acquisition was approved, as well as TD Bank, certain TD Bank related entities, and Schwab. The amended complaint asserts separate claims for breach of fiduciary duty by the TD Ameritrade officer, certain members of the TD Ameritrade board and TD Bank, and against Schwab for aiding and abetting such breaches, the allegation being that the amendment of the Insured Deposit Account Agreement TD Bank negotiated directly with Schwab allowed TD Bank to divert merger consideration from TD Ameritrade’s minority public stockholders. Plaintiff seeks to recover monetary damages, costs and attorneys’ fees. Schwab and the other defendants consider the allegations to be entirely without merit and on April 29, 2021, filed motions to dismiss the remaining claims in the lawsuit. Crago Order Routing Litigation : On July 13, 2016, a securities class action lawsuit was filed in the U.S. District Court for the Northern District of California on behalf of a putative class of customers executing equity orders through CS&Co. The lawsuit names CS&Co and CSC as defendants and alleges that an agreement under which CS&Co routed orders to UBS Securities LLC between July 13, 2011 and December 31, 2014 violated CS&Co’s duty to seek best execution. Plaintiffs seek unspecified damages, interest, injunctive and equitable relief, and attorneys’ fees and costs. After a first amended complaint was dismissed with leave to amend, plaintiffs filed a second amended complaint on August 14, 2017. Defendants again moved to dismiss, and in a decision issued December 5, 2017, the court denied the motion. Defendants have answered the complaint to deny all allegations, and are vigorously contesting the lawsuit. Plaintiffs filed a motion for class certification on April 30, 2021, which defendants are opposing. Ford Order Routing Litigation : On September 15, 2014, TDA Holding, TD Ameritrade, Inc. and its former CEO, Frederick J. Tomczyk, were sued on behalf of a putative class of TD Ameritrade, Inc. clients alleging that defendants failed to seek best execution and made misrepresentations and omissions regarding its order routing practices. Plaintiffs seek unspecified damages and injunctive and other relief. On September 14, 2018, the District Court granted plaintiff’s motion for class certification, and defendants petitioned for an immediate appeal of the District Court’s class certification decision. On April 23, 2021, the U.S. Court of Appeals, 8th Circuit, issued a decision reversing the District Court’s certification on a class and remanding the case back to the District Court for further proceedings. Defendants are vigorously contesting the lawsuit, and the Company is unable to predict the outcome or any potential loss that could result.

Restructuring and Related Activities [Abstract]
Exit and Other Related Liabilities	Exit and Other Related Liabilities As a result of the significant growth seen in recent quarters across key client volume metrics, including the number of active brokerage accounts, DATs, and peak daily trades, the Company has increased the scope of technology work related to the integration of TD Ameritrade. We have commenced greater technology build-out to support the expanded volumes of our combined client base. Based on our current integration plans and expanded scope of technology work, the Company expects to complete client conversion within 30 to 36 months from the October 6, 2020 date of acquisition. To achieve our integration objectives, the Company expects to recognize significant additional acquisition and integration-related costs and capital expenditures throughout the integration process. Such acquisition and integration-related costs have included and are expected to continue to include professional fees, such as legal, advisory, and accounting fees, costs for technology enhancements, and compensation and benefits expenses for employees and contractors involved in the integration work. The Company’s acquisition and integration-related spending also includes exit and other related costs, such as severance and other employee termination benefits, retention costs, as well as costs related to facility closures, including accelerated amortization and depreciation or impairments of assets in those locations. Exit and other related costs are a component of the Company’s overall acquisition and integration-related spending, and support the Company’s ability to achieve integration objectives including expected synergies. Our estimates of the nature, amounts, and timing of recognition of acquisition and integration-related costs are subject to change based on a number of factors, including the expected duration and complexity of the integration process and the heightened uncertainty of the current economic environment. More specifically, factors that could cause variability in our expected acquisition and integration-related costs include the level of employee attrition, workforce redeployment from eliminated positions into open roles, changes in the levels of client activity, and increased real estate-related exit cost variability due to the effects of the COVID-19 pandemic. Inclusive of costs recognized through June 30, 2021, Schwab currently expects to incur total exit and other related costs for the integration of TD Ameritrade ranging from $650 million to $1 billion, consisting of employee compensation and benefits, facility exit costs, and certain other costs. During the three and six months ended June 30, 2021, the Company incurred pre-tax charges of $47 million and $90 million for acquisition-related exit costs, respectively. The Company expects the remaining exit and other related costs will be incurred and charged to expense over the next 27 to 39 months; some costs are expected to be incurred after client conversion. In addition to ASC 420 Exit or Disposal Cost Obligations , certain of the costs associated with these activities are accounted for in accordance with ASC 360 Property, Plant and Equipment , ASC 712 Compensation – Nonretirement Post Employment Benefits , ASC 718 Compensation – Stock Compensation , and ASC 842 Leases .

Offsetting [Abstract]
Financial Instruments Subject to Off-Balance Sheet Credit Risk	Financial Instruments Subject to Off-Balance Sheet Credit Risk Resale agreements: Schwab enters into collateralized resale agreements principally with other broker-dealers, which could result in losses in the event the counterparty fails to purchase the securities held as collateral for the cash advanced and the fair value of the securities declines. To mitigate this risk, Schwab requires that the counterparty deliver securities to a custodian, to be held as collateral, with a fair value at or in excess of the resale price. Schwab also sets standards for the credit quality of the counterparty, monitors the fair value of the underlying securities as compared to the related receivable, including accrued interest, and requires additional collateral where deemed appropriate. The collateral provided under these resale agreements is utilized to meet obligations under broker-dealer client protection rules, which place limitations on our ability to access such segregated securities. For Schwab to repledge or sell this collateral, we would be required to deposit cash and/or securities of an equal amount into our segregated reserve bank accounts in order to meet our segregated cash and investment requirement. Schwab’s resale agreements as of June 30, 2021 and December 31, 2020 were not subject to master netting arrangements. Securities lending: Schwab loans brokerage client securities temporarily to other brokers and clearing houses in connection with its securities lending activities and receives cash as collateral for the securities loaned. Increases in security prices may cause the fair value of the securities loaned to exceed the amount of cash received as collateral. In the event the counterparty to these transactions does not return the loaned securities or provide additional cash collateral, we may be exposed to the risk of acquiring the securities at prevailing market prices in order to satisfy our client obligations. Schwab mitigates this risk by requiring credit approvals for counterparties, monitoring the fair value of securities loaned, and requiring additional cash as collateral when necessary. In addition, most of our securities lending transactions are through a program with a clearing organization, which guarantees the return of cash to us. We also borrow securities from other broker-dealers to fulfill short sales by brokerage clients and deliver cash to the lender in exchange for the securities. The fair value of these borrowed securities was $1.1 billion and $852 million at June 30, 2021 and December 31, 2020, respectively. Our securities lending transactions are subject to enforceable master netting arrangements with other broker-dealers; however, we do not net securities lending transactions. Therefore, the securities loaned and securities borrowed are presented gross in the condensed consolidated balance sheets.

Fair Value Disclosures [Abstract]
Fair Values of Assets and Liabilities	Fair Values of Assets and Liabilities Assets and liabilities measured at fair value on a recurring basis Schwab’s assets and liabilities measured at fair value on a recurring basis include: certain cash equivalents, certain investments segregated and on deposit for regulatory purposes, AFS securities, and certain other assets. The Company uses the market approach to determine the fair value of assets and liabilities. When available, the Company uses quoted prices in active markets to measure the fair value of assets and liabilities. Quoted prices for investments in exchange-traded securities represent end-of-day close prices published by exchanges. Quoted prices for money market funds and other mutual funds represent reported net asset values. When utilizing market data and bid-ask spread, the Company uses the price within the bid-ask spread that best represents fair value. When quoted prices in active markets do not exist, the Company uses prices obtained from independent third-party pricing services to measure the fair value of investment assets. We generally obtain prices from three independent third-party pricing sources for assets recorded at fair value. Our primary independent pricing service provides prices for our fixed income investments such as commercial paper; certificates of deposit; U.S. government and agency securities; state and municipal securities; corporate debt securities; asset-backed securities; foreign government agency securities; and non-agency commercial mortgage-backed securities. Such prices are based on observable trades, broker/dealer quotes, and discounted cash flows that incorporate observable information such as yields for similar types of securities (a benchmark interest rate plus observable spreads) and weighted-average maturity for the same or similar “to-be-issued” securities. We compare the prices obtained from the primary independent pricing service to the prices obtained from the additional independent pricing services to determine if the price obtained from the primary independent pricing service is reasonable. Schwab does not adjust the prices received from independent third-party pricing services unless such prices are inconsistent with the definition of fair value and result in material differences in the amounts recorded. For a description of the fair value hierarchy and Schwab’s fair value methodologies, see Item 8 – Note 2 in the 2020 Form 10-K. The Company did not adjust prices received from the primary independent third-party pricing service at June 30, 2021 or December 31, 2020.

Earnings Per Share [Abstract]
Earnings Per Common Share	Earnings Per Common Share For the three and six months ended June 30, 2021, the Company had voting and nonvoting common stock outstanding. Since the rights of the voting and nonvoting common stock are identical, except with respect to voting, the net income of the Company has been allocated on a proportionate basis to the two classes. Diluted earnings per share is calculated using the treasury stock method for outstanding stock options and non-vested restricted stock units and the if-converted method for nonvoting common stock. For further details surrounding the EPS computation, see Note 25 in the 2020 Form 10-K. EPS under the basic and diluted computations for both common stock and nonvoting common stock are as follows: Three Months Ended Six Months Ended 2021 2020 2021 2020 Common Common Stock – Nonvoting (1) Common Common Stock – Nonvoting (1) Common Common Stock – Nonvoting (1) Common Common Stock – Nonvoting (1) Basic earnings per share: Numerator Net income $ 1,212 $ 53 $ 671 N/A $ 2,634 $ 115 $ 1,466 N/A Preferred stock dividends and other (2) (142) (6) (50) N/A (234) (10) (88) N/A Net income available to common stockholders $ 1,070 $ 47 $ 621 N/A $ 2,400 $ 105 $ 1,378 N/A Denominator Weighted-average common shares outstanding — basic 1,807 79 1,288 N/A 1,805 79 1,287 N/A Basic earnings per share $ .59 $ .59 $ .48 N/A $ 1.33 $ 1.33 $ 1.07 N/A Diluted earnings per share: Numerator Net income available to common stockholders $ 1,070 $ 47 $ 621 N/A $ 2,400 $ 105 $ 1,378 N/A Reallocation of net income available to common 47 — N/A N/A 105 — N/A N/A Allocation of net income available to common $ 1,117 $ 47 $ 621 N/A $ 2,505 $ 105 $ 1,378 N/A Denominator Weighted-average common shares outstanding — basic 1,807 79 1,288 N/A 1,805 79 1,287 N/A Conversion of nonvoting shares to voting shares 79 — N/A N/A 79 — N/A N/A Common stock equivalent shares related to stock 10 — 6 N/A 10 — 7 N/A Weighted-average common shares outstanding — diluted (3) 1,896 79 1,294 N/A 1,894 79 1,294 N/A Diluted earnings per share $ .59 $ .59 $ .48 N/A $ 1.32 $ 1.32 $ 1.07 N/A (1) Nonvoting common stock was issued in conjunction with the October 6, 2020 acquisition of TD Ameritrade.
