Introduction and Basis of Presentation [Abstract]
Introduction and Basis of Presentation	1.Introduction and Basis of Presentation
	The Charles Schwab Corporation (CSC) is a savings and loan holding company engaged, through its subsidiaries, in wealth management, securities brokerage, banking, money management, and financial advisory services. Charles Schwab & Co., Inc. (Schwab) is a securities broker-dealer with over 325 domestic branch offices in 45 states, as well as a branch in each of the Commonwealth of Puerto Rico and London, England. In addition, Schwab serves clients in Hong Kong through one of CSC’s subsidiaries. Other subsidiaries include Charles Schwab Bank (Schwab Bank), a federal savings bank, and Charles Schwab Investment Management, Inc. (CSIM), the investment advisor for Schwab’s proprietary mutual funds, which are referred to as the Schwab Funds®, and for Schwab’s exchange-traded funds, which are referred to as the Schwab ETFs™.
	The accompanying unaudited condensed consolidated financial statements include CSC and its majority-owned subsidiaries (collectively referred to as the Company). Intercompany balances and transactions have been eliminated. These condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (U.S.), which require management to make certain estimates and assumptions that affect the reported amounts in the accompanying financial statements. Certain estimates relate to valuation of goodwill, allowance for loan losses, legal and regulatory reserves, and other-than-temporary impairment (OTTI) of securities available for sale and securities held to maturity. Actual results may differ from those estimates. These condensed consolidated financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the periods presented. These adjustments are of a normal recurring nature. The Company’s results for any interim period are not necessarily indicative of results for a full year or any other interim period. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.
	The Company’s significant accounting policies are included in note “2 – Summary of Significant Accounting Policies” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. There have been no significant changes to these accounting policies during the first quarter of 2015.

New Accounting Standards [Abstract]
New Accounting Standards	2.New Accounting Standards
	Adoption of New Accounting Standard
	In January 2014, the Financial Accounting Standards Board (FASB) issued new guidance for creditors of consumer mortgage loans, which was effective January 1, 2015. The guidance clarifies when physical possession of a property underlying a consumer mortgage loan transfers to the creditor, and therefore when a loan receivable should be derecognized and the real estate property underlying the loan should be recognized. The adoption of this new guidance in the first quarter of 2015 did not have an impact on the Company’s financial statements or earnings per common share (EPS) as the Company’s practice for recognizing foreclosed real estate was already consistent with the guidance.
	New Accounting Standards Not Yet Adopted
	In May 2014, the FASB issued new guidance on revenue recognition, which will become effective January 1, 2017. The guidance clarifies that revenue from contracts with customers should be recognized in a manner that depicts the timing of the related transfer of goods or performance of services at an amount that reflects the expected consideration. The Company is currently evaluating the impact of this new guidance on its financial statements and EPS.
	In February 2015, the FASB issued new guidance that amends the analysis a reporting entity must perform to determine whether it should consolidate certain types of legal entities. The new guidance will become effective January 1, 2016, and is applicable to all entities but provides an exception for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. The Company is currently evaluating the impact of this new guidance on its financial statements and EPS.
	In April 2015, the FASB issued new guidance that changes the presentation of debt issuance costs. The new guidance will require debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. Currently, debt issuance costs are presented as a separate asset. The new guidance, which will become effective January 1, 2016, will not impact the Company’s financial results or EPS as the change only affects the balance sheet presentation of debt issuance costs; recognition and measurement of debt issuance costs will not be affected.
	In April 2015, the FASB issued new guidance that clarifies customer’s accounting for fees paid in a cloud computing arrangement. Under the new guidance, if a cloud computing arrangement includes a software license, the customer shall account for the software license element of the arrangement consistent with the acquisition of other software licenses. If the cloud computing arrangement does not include a software license, the customer shall account for the arrangement as a service contract. The guidance will become effective January 1, 2016. The Company is currently evaluating the impact of this new guidance on its financial statements and EPS.

	There were no loans accruing interest that were contractually 90 days or more past due at March 31, 2015 or December 31, 2014. Nonperforming assets, which include nonaccrual loans and other real estate owned, totaled $40 million and $44 million at March 31, 2015 and December 31, 2014, respectively. Troubled debt restructurings were not material at March 31, 2015 or December 31, 2014.
	In addition to monitoring delinquency, the Company monitors the credit quality of residential real estate mortgages and HELOCs by stratifying the portfolios by the 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), as presented in the following tables. Borrowers’ FICO scores are provided by an independent third-party credit reporting service and were last updated in March 2015. The Origination LTV and Estimated Current LTV ratios 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 estimated by reference to a home price appreciation index.

Commitments and Contingencies [Abstract]
Commitments and Contingencies
	6.Commitments and Contingencies
	The Company 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. The Company partially satisfies the margin requirements by arranging unsecured standby letter of credit agreements (LOCs), in favor of the Options Clearing Corporation, which are issued by multiple banks. At March 31, 2015, the aggregate face amount of these LOCs totaled $240 million. There were no funds drawn under any of these LOCs at March 31, 2015. In connection with its securities lending activities, the Company 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 cash and securities it has posted as collateral. However, the potential requirement for the Company to make payments under these arrangements is remote. Accordingly, no liability has been recognized for these guarantees.
	The Company has recorded a liability of $37 million for unfunded commitments related to investments in qualified affordable housing projects at March 31, 2015, which is included in accrued expenses and other liabilities on the balance sheet. These commitments are expected to be paid during the years from 2015 to 2020. The Company also recorded a corresponding asset for the funded and unfunded investments in qualified affordable housing projects of $44 million at March 31, 2015, which is included in other assets on the balance sheet.
	Legal contingencies: The Company 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.
	The Company 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 certain 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. However, 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; potential opportunities for settlement and the status of any settlement discussions; and potential insurance coverage and indemnification. It may not be possible to reasonably estimate potential liability, if any, or 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.
	Total Bond Market Fund Litigation: On August 28, 2008, a class action lawsuit was filed in the U.S. District Court for the Northern District of California on behalf of investors in the Schwab Total Bond Market Fund™. The lawsuit, which alleges violations of state law and federal securities law in connection with the fund’s investment policy, names Schwab Investments (registrant and issuer of the fund’s shares) and CSIM as defendants. Allegations include that the fund improperly deviated from its stated investment objectives by investing in collateralized mortgage obligations (CMOs) and investing more than 25% of fund assets in CMOs and mortgage-backed securities without obtaining a shareholder vote. Plaintiffs seek unspecified compensatory and rescission damages, unspecified equitable and injunctive relief, costs and attorneys’ fees. Plaintiffs’ federal securities law claim and certain of plaintiffs’ state law claims were dismissed. On August 8, 2011, the court dismissed plaintiffs’ remaining claims with prejudice. Plaintiffs appealed to the Ninth Circuit, which issued a ruling on March 9, 2015 reversing the district court’s dismissal of the case and remanding the case for further proceedings. Defendants’ petition for rehearing was denied on April 28, 2015.
	Other Regulatory Matters: On April 16, 2012, optionsXpress, Inc. was charged by the SEC in an administrative proceeding alleging violations of the firm’s close-out obligations under Regulation SHO (short sale delivery rules) in connection with certain customer trading activity. Following trial, in a decision issued June 7, 2013, the judge held that the firm had violated Regulation SHO and aided and abetted fraudulent trading activity by its customer, and ordered the firm and the customer to pay disgorgement and penalties in an amount which would not be material. The Company continues to dispute the allegations and is appealing the decision.

Offsetting Assets and Liabilities [Abstract]
Offsetting Assets and Liabilities	7.Offsetting Assets and Liabilities
	Resale and repurchase 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 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 fair value of collateral received in connection with resale agreements that are available to be repledged or sold was $10.0 billion at March 31, 2015 and $10.4 billion at December 31, 2014. Schwab utilizes the collateral provided under these resale agreements to meet obligations under broker-dealer client protection rules, which place limitations on its ability to access such segregated securities. For Schwab to repledge or sell this collateral, it would be required to deposit cash and/or securities of an equal amount into its segregated reserve bank accounts in order to meet its segregated cash and investment requirement. The Company’s resale agreements are not subject to master netting arrangements.
	Securities lending: The Company loans client securities temporarily to other brokers 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, the Company may be exposed to the risk of acquiring the securities at prevailing market prices in order to satisfy its client obligations. The Company mitigates this risk by requiring credit approvals for counterparties, monitoring the fair value of securities loaned, and requiring additional cash as collateral when necessary. The fair value of client securities pledged in securities lending transactions to other broker-dealers was $1.7 billion at March 31, 2015 and $1.3 billion at December 31, 2014. The Company has also pledged a portion of its securities owned in connection with securities lending transactions to other broker-dealers. Additionally, the Company borrows securities from other broker-dealers to fulfill short sales by clients and delivers cash to the lender in exchange for the securities. The fair value of these borrowed securities was $44 million at March 31, 2015 and $88 million at December 31, 2014. All of the Company’s securities lending transactions are subject to enforceable master netting arrangements with other broker-dealers. However, the Company does not net securities lending transactions and therefore, the Company’s securities loaned and securities borrowed are presented gross in the consolidated balance sheets.
	The following table presents information about the Company’s resale agreements and securities lending activity to enable the users of the Company’s financial statements to evaluate the potential effect of rights of setoff between these recognized assets and recognized liabilities at March 31, 2015 and December 31, 2014.

Earnings Per Common Share	10.Earnings Per Common Share
	Basic EPS is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding during the period. The computation of diluted EPS is similar to the computation of basic EPS except that the denominator is increased to include the number of additional common shares that would have been outstanding if dilutive potential common shares had been issued. Dilutive potential common shares include, if dilutive, the effect of outstanding stock options and unvested restricted stock awards and units. EPS under the basic and diluted computations is as follows:

Regulatory Requirements	11.Regulatory Requirements
	CSC is a savings and loan holding company and Schwab Bank, CSC’s depository institution subsidiary, is a federal savings bank. CSC is subject to supervision and regulation by the Board of Governors of the Federal Reserve System (the Federal Reserve). Schwab Bank is subject to supervision and regulation by the Office of the Comptroller of the Currency (the OCC), as its primary regulator, the Federal Deposit Insurance Corporation, as its deposit insurer, and the Consumer Financial Protection Bureau. CSC is required to serve as a source of strength for Schwab Bank. Prior to January 1, 2015, CSC, as a savings and loan holding company, was not subject to certain statutory capital requirements. Beginning on January 1, 2015, CSC is subject to new capital requirements set by the Federal Reserve.
	Schwab Bank is subject to regulation and supervision and to various requirements and restrictions under federal and state laws, including regulatory capital guidelines. Among other things, these requirements also restrict and govern the terms of affiliate transactions, such as extensions of credit and repayment of loans between Schwab Bank and CSC or CSC’s other subsidiaries. In addition, Schwab Bank is required to provide notice to and may be required to obtain approval of the OCC and the Federal Reserve to declare dividends to CSC. The federal banking agencies have broad powers to enforce these regulations, including the power to terminate deposit insurance, impose substantial fines and other civil and criminal penalties, and appoint a conservator or receiver. Under the Federal Deposit Insurance Act, Schwab Bank could be subject to restrictive actions if it were to fall within one of the lowest three of five capital categories. CSC and Schwab Bank are required to maintain minimum capital levels as specified in federal banking laws and regulations. Failure to meet the minimum levels could result in certain mandatory and possibly additional discretionary actions by the regulators that, if undertaken, could have a direct material effect on CSC and Schwab Bank. At March 31, 2015, CSC and Schwab Bank met the capital level requirements.
	The new regulatory capital and ratios for CSC and Schwab Bank at March 31, 2015 are as follows:

Under the alternative method, a broker-dealer may not repay subordinated borrowings, pay cash dividends, or make any unsecured advances or loans to its parent company or employees if such payment would result in a net capital amount of less than 5% of aggregate debit balances or less than 120% of its minimum dollar requirement.
	optionsXpress, Inc. is also subject to Commodity Futures Trading Commission Regulation 1.17 (Reg. 1.17) under the Commodity Exchange Act, which also requires the maintenance of minimum net capital. optionsXpress, Inc., as a futures commission merchant, is required to maintain minimum net capital equal to the greater of its net capital requirement under Reg. 1.17 ($1 million), or the sum of 8% of the total risk margin requirements for all positions carried in client accounts and 8% of the total risk margin requirements for all positions carried in non-client accounts (as defined in Reg. 1.17).
