Organization, Consolidation and Presentation of Financial Statements [Abstract]
Introduction and Basis of Presentation	Introduction and Basis of Presentation CSC is a savings and loan holding company engaged, through its subsidiaries, in wealth management, securities brokerage, banking, asset management, custody, and financial advisory services. Schwab is a securities broker-dealer with over 345 domestic branch offices in 46 states, as well as a branch in the Commonwealth of Puerto Rico. In addition, Schwab serves clients in London, England and Hong Kong through one of CSC’s subsidiaries. Other subsidiaries include Schwab Bank, a federal savings bank, and CSIM, the investment advisor for Schwab Funds ® and 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 generally accepted accounting principles in the U.S. (GAAP), which require management to make certain estimates and assumptions that affect the reported amounts in the accompanying financial statements. Certain estimates relate to other-than-temporary impairment (OTTI) of investment securities, valuation of goodwill, allowance for loan losses, legal and regulatory reserves, and income taxes. 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 2016 Form 10-K. The Company’s significant accounting policies are included in Note 2 in the 2016 Form 10-K. There have been no significant changes to these accounting policies during the first nine months of 2017 except as described in Note 2 below. Principles of Consolidation The Company evaluates for consolidation all entities in which it has financial interests, except for money market funds which are specifically excluded from consolidation guidance. For an entity subject to consolidation, the Company evaluates whether the Company’s interest in the entity constitutes a controlling financial interest under either the variable interest entity (VIE) model or a voting interest entity (VOE) model. Based upon the Company’s assessments, the Company is not deemed to have a controlling financial interest in and, therefore, is not required to consolidate any VIEs. See Note 5 for further information about VIEs. The Company consolidates all VOEs in which it has majority-voting interests. For investments in entities in which the Company does not have a controlling financial interest, the Company accounts for those investments under the equity method of accounting when the Company has the ability to exercise significant influence over operating and financing decisions of the entity. Investments in entities for which the Company does not have the ability to exercise significant influence are generally carried at cost. Both equity method and cost method investments are included in other assets on the condensed consolidated balance sheets.

New Accounting Standards

Accounting Changes and Error Corrections [Abstract]
New Accounting Standards	New Accounting Standards Adoption of New Accounting Standards The Company adopted ASU 2016-09, “Stock Compensation – Improvements to Employee Share-Based Payment Accounting (Topic 718),” on a prospective basis as of January 1, 2017. This guidance requires entities to recognize the income tax effects for the difference between GAAP and federal income tax treatment (i.e., excess tax benefit or deficiency) of share-based awards in the income statement when the awards vest or are settled, rather than recording such effects in additional paid-in capital. As a result, the Company’s tax expense was reduced by approximately $11 million and $ 47 million in the third quarter and first nine months of 2017 , respectively. Future effects will depend on the Company’s share price, restricted stock vesting, and the volume of equity incentive options exercised. ASU 2016-09 also provides entities with an accounting policy election to account for the impact of forfeitures of awards on compensation expense as they occur or continue with the current practice of estimating forfeitures at the grant date to determine the number of awards expected to vest and adjusting that estimate as necessary. The Company has elected to continue to follow the current practice of estimating forfeitures. New Accounting Standards Not Yet Adopted ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” provides new guidance on revenue recognition. 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 Financial Accounting Standards Board (FASB) has subsequently issued several amendments to the standard, including deferral of the effective date until January 1, 2018, clarification of principal versus agent considerations, narrow scope improvements, and other technical corrections. Entities may elect either full or modified retrospective transition. Full retrospective transition will require a cumulative effect adjustment to retained earnings as of the earliest comparative period presented. Modified retrospective transition will require a cumulative effect adjustment to retained earnings as of the beginning of the reporting period in which the entity first applies the new guidance. The Company plans to adopt the revenue recognition guidance in the first quarter of 2018 using the modified retrospective method. The guidance does not apply to the Company’s loans and securities. Accordingly, the Company does not expect an impact to net interest revenue. The Company believes the primary areas of potential impact for the Company are (i) the capitalization of costs to obtain a contract and (ii) gross versus net presentation of certain revenue streams in the income statement. The Company believes adoption of this guidance will likely alter the timing of recognition for costs to obtain a contract in the income statement. The next phase of the Company’s implementation work is to evaluate the disclosure provisions. The Company does not expect this guidance will have a material impact on its financial statements and EPS. ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10),” will be effective January 1, 2018 and requires a cumulative effect adjustment to the balance sheet as of the beginning of the year of initial application, except for certain changes that require prospective adoption. The main provisions of the guidance require: (i) equity investments to be measured at fair value, with changes in fair value recognized in net income, unless the equity method is applied or the equity investments do not have readily determinable fair values in which case a practical alternative may be elected; (ii) use of an exit price when measuring the fair value of financial instruments for disclosures; and (iii) separate presentation of financial assets and liabilities by measurement category and form of instrument on the balance sheet or in the accompanying notes. The Company does not expect this guidance will have a material impact on its financial statements and EPS. ASU 2016-02, “Leases (Topic 842),” amends the accounting for leases by lessees and lessors. The primary change from the new guidance is the recognition of right-of-use assets and lease liabilities by lessees for those leases classified as operating leases. Additional changes include accounting for lease origination and executory costs, required lessee reassessments during the lease term due to changes in circumstances, and expanded lease disclosures. ASU 2016-02 will become effective January 1, 2019, with early adoption permitted, and requires entities to apply the new guidance using a modified retrospective transition. Modified retrospective transition requires entities to apply the new guidance as of the beginning of the earliest comparative period presented in the financial statements in which the entity first applies the new standard. Certain transition relief is permitted if elected by the entity. The adoption of ASU 2016-02 will result in the Company recognizing a right-of-use asset and lease liability on the consolidated balance sheet based on the present value of remaining operating lease payments (see Note 14 of the Company’s 2016 Form 10-K for the undiscounted future annual minimum rental commitments for operating leases). The Company does not expect this guidance will have a material impact on its EPS. ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” provides new guidance for recognizing impairment of most debt instruments measured at amortized cost, including loans and held to maturity (HTM) debt securities. The new guidance will require estimating current expected credit losses (CECL) over the remaining life of an instrument or a portfolio of instruments with similar risk characteristics based on relevant information about past events, current conditions, and reasonable forecasts. The initial estimate of, and the subsequent changes in, CECL will be recognized as credit loss expense through current earnings and will be reflected as an allowance for credit losses offsetting the carrying value of the financial instrument(s) on the balance sheet. The new guidance also amends the OTTI model for AFS debt securities by requiring the use of an allowance, rather than directly reducing the carrying value of the security, and eliminating consideration of the length of time such security has been in an unrealized loss position as a factor in concluding whether a credit loss exists. ASU 2016-13 will become effective January 1, 2020, with early adoption permitted as of January 1, 2019. The new guidance will be applied through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the entity applies the new guidance except that a prospective transition is required for AFS debt securities for which an OTTI had been recognized before the effective date. The Company is currently evaluating the impact of this guidance on its financial statements and EPS. ASU 2017-08, “Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities,” shortens the amortization period for the premium on certain callable debt securities to the earliest call date. The amendments are applicable to any purchased individual debt security with an explicit and noncontingent call feature that is callable at a fixed price on a preset date. The amendments do not impact the accounting for callable debt securities held at a discount. ASU 2017-08 will become effective on January 1, 2019, with early adoption permitted including in an interim period. The amendments will be applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. The Company is currently evaluating the impact of adopting this guidance on its financial statements and EPS.

These securities had a total net unrealized loss of $227 million before income tax in AOCI on the date of transfer. The transfer was made to mitigate the potential volatility in regulatory capital from changes in market values in the AFS securities portfolio and the related impact to AOCI once the Company crosses $250 billion in consolidated assets. The year after the Company surpasses $250 billion in consolidated assets, it can no longer exclude AOCI from regulatory capital. The transfer included U.S. agency mortgage-backed securities, asset-backed securities, corporate debt securities, and U.S. state and municipal securities. The unrealized holding gains and losses on the date of transfer are reported as a separate component of AOCI and as an adjustment to the purchase premium and discount on the securities transferred. The separate component of AOCI will be amortized or accreted into interest income over the remaining life of the securities transferred, offsetting the revised premium or discount amortization or accretion on the transferred assets .

The Company had commitments to extend credit related to unused HELOCs, pledged asset lines (PALs), and other lines of credit, which totaled $9.6 billion and $8.4 billion at September 30, 2017 and December 31, 2016 , respectively. The Company had commitments to purchase First Mortgage loans of $459 million and $466 million at September 30, 2017 and December 31, 2016 , respectively. All PALs were fully collateralized by securities with fair values in excess of borrowings at September 30, 2017 and December 31, 2016 . Schwab Bank provides a co-branded loan origination program for Schwab Bank clients (the Program) with Quicken Loans, Inc. (Quicken Loans ® ). Pursuant to the Program, Quicken Loans originates and services First Mortgages and HELOCs for Schwab Bank clients. Under the Program, Schwab Bank purchases certain First Mortgages and HELOCs that are originated by Quicken Loans. Schwab Bank purchased First Mortgages of $696 million and $858 million during the third quarters of 2017 and 2016 , respectively, and $2.0 billion and $2.1 billion during the first nine months of 2017 and 2016 , respectively. Schwab Bank purchased HELOCs with commitments of $115 million and $93 million during the third quarters of 2017 and 2016 , respectively, and $344 million and $315 million during the first nine months of 2017 and 2016 , respectively.

There were no loans accruing interest that were contractually 90 days or more past due at September 30, 2017 or December 31, 2016 . Nonperforming assets, which include nonaccrual loans and other real estate owned, totaled $29 million and $31 million at September 30, 2017 and December 31, 2016 , respectively. Impaired assets, which include nonaccrual loans, other real estate owned and troubled debt restructurings, totaled $38 million and $45 million at September 30, 2017 and December 31, 2016 , respectively. Troubled debt restructurings were not material at September 30, 2017 or December 31, 2016 . In addition to monitoring delinquency, the Company 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 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 were last updated in September 2017. 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 estimated by reference to a home price appreciation index. As of September 30, 2017 and December 31, 2016 , 47% and 48% of the Company’s HELOC and First Mortgage portfolio was concentrated in California. These loans have performed in a manner consistent with the portfolio as a whole. The credit quality indicators of the Company’s bank loan portfolio are detailed below: September 30, 2017 Balance Weighted Average Utilization (1) Percent of Residential real estate mortgages: Estimated Current LTV < 70% $ 8,896 776 N/A 0.05 % >70% – < 90% 893 768 N/A 0.47 % >90% – < 100% 8 720 N/A 4.60 % >100% 5 724 N/A — Total $ 9,802 776 N/A 0.09 % Home equity loans and lines of credit: Estimated Current LTV (2) < 70% $ 1,855 772 33 % 0.16 % >70% – < 90% 160 757 49 % 0.46 % >90% – < 100% 17 747 74 % 2.08 % >100% 10 718 74 % 2.12 % Total $ 2,042 770 34 % 0.21 % Pledged asset lines: Weighted-Average LTV (2) =70% $ 4,279 767 42 % — (1) The Utilization Rate is calculated using the outstanding balance divided by the associated total line of credit.

The Company’s adjustable rate mortgages have initial fixed interest rates for three to ten years and interest rates that adjust annually thereafter. Approximately 34% of these mortgages consisted of loans with interest-only payment terms. The interest rates on approximately 56% of these interest-only loans are not scheduled to reset for three or more years. The Company’s mortgage loans do not include interest terms described as temporary introductory rates below current market rates. The Company’s 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. HELOCs that convert to an amortizing loan may experience higher delinquencies and higher loss rates than those in the initial draw period. The Company’s allowance for loan loss methodology takes this increased inherent risk into consideration. The following table presents when current outstanding HELOCs will convert to amortizing loans: September 30, 2017 Balance Converted to an amortizing loan by period end $ 447 Within 1 year 475 > 1 year – 3 years 346 > 3 years – 5 years 148 > 5 years 626 Total $ 2,042 At September 30, 2017 , $1.6 billion 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, the Company also monitors credit risk by reviewing the delinquency status of the first lien loan on the associated property. At September 30, 2017 , approximately 39% of the HELOC borrowers that had a balance only paid the minimum amount of interest due.

Variable Interest Entities

Variable Interest Entities	9 Months Ended

Variable Interest Entities [Abstract]
Variable Interest Entities	Variable Interest Entities A VIE requires consolidation by the entity’s primary beneficiary. The Company evaluates all entities in which it has a financial interest to determine if the entity is a VIE and if so, whether the Company is the primary beneficiary. See Principles of Consolidation in Note 1 for discussion of the Company’s evaluations of VIEs and whether it is deemed to be the primary beneficiary of any VIEs in which it holds an interest. The Company was not the primary beneficiary of, and therefore not required to consolidate any VIEs at September 30, 2017 and December 31, 2016 . As of September 30, 2017 and December 31, 2016 , the majority of the Company’s VIEs related to Schwab Bank’s Low-Income Housing Tax Credit (LIHTC) investments. Schwab Bank’s LIHTC investments are accounted for using the proportional amortization method. Amortization, tax credits, and other tax benefits recognized in relation to LIHTC investments are included in taxes on income in the condensed consolidated statements of income. For further information on the Community Reinvestment Act (CRA) and Schwab Bank’s LIHTC investments, see Note 2 and Note 10 in the 2016 Form 10-K. Aggregate assets, liabilities, and maximum exposure to loss The aggregate assets, liabilities, and maximum exposure to loss from those VIEs in which the Company holds a variable interest, but as to which the Company has concluded it is not the primary beneficiary, are summarized in the table below: September 30, 2017 December 31, 2016 Aggregate Aggregate Maximum Aggregate Aggregate Maximum LIHTC investments (1) $ 253 $ 169 $ 253 $ 189 $ 135 $ 189 Other CRA investments (2) 63 — 82 60 — 80 Total $ 316 $ 169 $ 335 $ 249 $ 135 $ 269 (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 recorded using either the cost method or the equity method. Aggregate assets are included in either other assets or bank loans – net on the condensed consolidated balance sheets. The Company’s maximum exposure to loss would result from the loss of the investments, including any committed amounts. During the nine months ended September 30, 2017 and 2016 , the Company did not provide or intend to provide financial or other support to the VIEs that it was not contractually required to provide. Schwab Bank’s funding of these remaining commitments is dependent upon the occurrence of certain conditions and Schwab Bank expects to pay substantially all of these commitments between 2017 and 2020 .

The Senior Notes have a fixed interest rate of 3.200% with interest payable semi-annually. The Company’s long-term debt at September 30, 2017 had a weighted-average interest rate of 3.11% . Annual maturities on long-term debt outstanding are as follows: September 30, 2017 2017 $ 3 2018 908 2019 8 2020 709 2021 9 Thereafter 1,657 Total maturities 3,294 Unamortized discount, net (13 ) Debt issuance costs (13 ) Total long-term debt $ 3,268 Short-term borrowings: Schwab Bank maintains a secured credit facility with the Federal Home Loan Bank of San Francisco (FHLB). Amounts available under this facility are dependent on the value of Schwab Bank’s First Mortgages, HELOCs, and investment securities that are pledged as collateral. As of September 30, 2017 , the collateral pledged by Schwab Bank provided a total borrowing capacity of $19.9 billion including the $5.0 billion outstanding. The Company could increase its borrowing capacity by pledging additional securities. At December 31, 2016 , there were no amounts outstanding under this facility. As a condition of the FHLB borrowings, Schwab Bank is required to hold FHLB stock, with the investment recorded in other assets on the condensed consolidated balance sheets. The investment in FHLB was $135 million at September 30, 2017 and $81 million at December 31, 2016 . CSC has authorization from its Board of Directors to issue Commercial Paper Notes not to exceed $1.5 billion . Management has set a current limit for the commercial paper program not to exceed the amount of the committed, unsecured credit facility, which was $750 million at September 30, 2017 . CSC had no Commercial Paper Notes outstanding at September 30, 2017 and December 31, 2016 . CSC and Schwab also have access to uncommitted, unsecured bank credit lines with several banks. Schwab had no borrowings outstanding under these lines at September 30, 2017 and December 31, 2016 .

Commitments and Contingencies

Commitments and Contingencies	9 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Guarantees and indemnifications: 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 several banks. At September 30, 2017 , the aggregate face amount of these LOCs totaled $295 million . There were no funds drawn under any of these LOCs at September 30, 2017 . 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. The potential requirement for the Company to make payments under these arrangements is remote. Accordingly, no liability has been recognized for these guarantees. 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. 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 alleged violations of state law and federal securities law in connection with the fund’s investment policy, named CSIM, Schwab Investments (registrant and issuer of the fund’s shares) and certain current and former fund trustees 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 fundholder vote. Plaintiff seeks unspecified compensatory and rescission damages, unspecified equitable and injunctive relief, costs and attorneys’ fees.

Offsetting [Abstract]
Offsetting Assets and Liabilities	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 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. 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 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, 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 Company borrows securities from other broker-dealers to fulfill short sales by brokerage clients and delivers cash to the lender in exchange for the securities. The fair value of these borrowed securities was $336 million at September 30, 2017 and $213 million at December 31, 2016 . 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. Therefore, the Company’s securities loaned and securities borrowed are presented gross in the condensed 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 September 30, 2017 and December 31, 2016 .

(3) Included in receivables from brokers, dealers, and clearing organizations in the Company’s condensed consolidated balance sheets. (4) Included in payables to brokers, dealers, and clearing organizations in the Company’s condensed consolidated balance sheets. (5) Securities loaned are predominantly comprised of equity securities held in client brokerage accounts with overnight and continuous remaining contractual maturities. Margin lending: Clients with margin loans have agreed to allow the Company to pledge collateralized securities in their brokerage accounts in accordance with federal regulations. The following table summarizes the fair value of client securities available, under such regulations, for the Company to utilize as collateral, and the amounts pledged by the Company: September 30, 2017 December 31, 2016 Fair value of client securities available to be pledged $ 23,520 $ 21,516 Fair value of client securities pledged for: Securities lending to other broker-dealers 1,115 1,626 Fulfillment of client short sales 2,281 2,048 Fulfillment of requirements with the Options Clearing Corporation (1) 1,949 1,519 Total collateral pledged $ 5,345 $ 5,193 Note: Excludes amounts available and pledged for securities lending from fully-paid client securities.

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 The Company’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, other securities owned, and AFS securities. 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. 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 do not exist, the Company uses prices obtained from independent third-party pricing services to measure the fair value of investment assets. The Company generally obtains prices from at least three independent pricing sources for assets recorded at fair value. The Company’s primary independent pricing service provides prices based on observable trades 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. The Company compares the prices obtained from its 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. The Company 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 a material difference in the recorded amounts. Fair value of other financial instruments Descriptions of the valuation methodologies and assumptions used to estimate the fair value of other financial instruments are described below. The Company’s financial instruments not recorded at fair value but for which fair value can be approximated and disclosed include: • Cash and cash equivalents are short-term in nature and accordingly are recorded at amounts that approximate fair value. • Cash and investments segregated and on deposit for regulatory purposes include cash and securities purchased under resale agreements. Securities purchased under resale agreements are short-term in nature and are backed by collateral that both exceeds the carrying value of the resale agreement and is highly liquid in nature. Accordingly, the carrying values of these financial instruments approximate their fair values. • Receivables from/payables to brokers, dealers, and clearing organizations are short-term in nature, recorded at contractual amounts and historically have been settled at those values. Accordingly, the carrying values of these financial instruments approximate their fair values. • Receivables from/payables to brokerage clients — net are short-term in nature, recorded at contractual amounts and historically have been settled at those values. Accordingly, the carrying values of these financial instruments approximate their fair values. • HTM securities – The fair values of HTM securities are obtained using an independent third-party pricing service similar to investment assets recorded at fair value as discussed above. • Bank loans – The fair values of the Company’s First Mortgages and HELOCs are estimated based on prices of mortgage-backed securities collateralized by similar types of loans. PALs are non-purpose revolving lines of credit secured by eligible assets; accordingly, the carrying values of these loans approximate their fair values. • Financial instruments included in other assets primarily consist of LIHTC investments, cost method investments, and FHLB stock, whose carrying values approximate their fair values. FHLB stock is recorded at par, which approximates its fair value. • Bank deposits have no stated maturity and are recorded at the amount payable on demand as of the balance sheet date. The carrying values of these deposits approximate their fair values. • Financial instruments included in accrued expenses and other liabilities consist of drafts payable and certain amounts due under contractual obligations, including unfunded LIHTC commitments. The carrying values of these instruments approximate their fair values. • Short-term borrowings consist of commercial paper, borrowings on Schwab’s uncommitted, unsecured bank credit lines, and funds drawn on Schwab Bank’s secured credit facility with the Federal Home Loan Bank of San Francisco. Due to the short-term nature of these borrowings, carrying value approximates fair value. • Long-term debt – Except for the finance lease obligation, the fair values of long-term debt are estimated using indicative, non-binding quotes from independent brokers. The Company validates indicative prices for its debt through comparison to other independent non-binding quotes. The finance lease obligation is recorded at carrying value, which approximates fair value. • Firm commitments to extend credit – The Company extends credit to banking clients through HELOCs and PALs. The Company considers the fair value of these unused commitments to not be material because the interest rates earned on these balances are based on floating interest rates that reset monthly. For a description of the fair value hierarchy, see Note 2 in the 2016 Form 10-K. There were no significant changes in these policies and methodologies during the first nine months of 2017 . The Company did not transfer any assets or liabilities between Level 1, Level 2, or Level 3 during the nine months ended September 30, 2017 , or the year ended December 31, 2016 . In addition, the Company did not adjust prices received from the primary independent third-party pricing service at September 30, 2017 or December 31, 2016 .

Accounting Changes and Error Corrections [Abstract]
Adoption of New Accounting Standards and New Accounting Standards Not Yet Adopted	Adoption of New Accounting Standards The Company adopted ASU 2016-09, “Stock Compensation – Improvements to Employee Share-Based Payment Accounting (Topic 718),” on a prospective basis as of January 1, 2017. This guidance requires entities to recognize the income tax effects for the difference between GAAP and federal income tax treatment (i.e., excess tax benefit or deficiency) of share-based awards in the income statement when the awards vest or are settled, rather than recording such effects in additional paid-in capital. As a result, the Company’s tax expense was reduced by approximately $11 million and $ 47 million in the third quarter and first nine months of 2017 , respectively. Future effects will depend on the Company’s share price, restricted stock vesting, and the volume of equity incentive options exercised. ASU 2016-09 also provides entities with an accounting policy election to account for the impact of forfeitures of awards on compensation expense as they occur or continue with the current practice of estimating forfeitures at the grant date to determine the number of awards expected to vest and adjusting that estimate as necessary. The Company has elected to continue to follow the current practice of estimating forfeitures. New Accounting Standards Not Yet Adopted ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” provides new guidance on revenue recognition. 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 Financial Accounting Standards Board (FASB) has subsequently issued several amendments to the standard, including deferral of the effective date until January 1, 2018, clarification of principal versus agent considerations, narrow scope improvements, and other technical corrections. Entities may elect either full or modified retrospective transition. Full retrospective transition will require a cumulative effect adjustment to retained earnings as of the earliest comparative period presented. Modified retrospective transition will require a cumulative effect adjustment to retained earnings as of the beginning of the reporting period in which the entity first applies the new guidance. The Company plans to adopt the revenue recognition guidance in the first quarter of 2018 using the modified retrospective method. The guidance does not apply to the Company’s loans and securities. Accordingly, the Company does not expect an impact to net interest revenue. The Company believes the primary areas of potential impact for the Company are (i) the capitalization of costs to obtain a contract and (ii) gross versus net presentation of certain revenue streams in the income statement. The Company believes adoption of this guidance will likely alter the timing of recognition for costs to obtain a contract in the income statement. The next phase of the Company’s implementation work is to evaluate the disclosure provisions. The Company does not expect this guidance will have a material impact on its financial statements and EPS. ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10),” will be effective January 1, 2018 and requires a cumulative effect adjustment to the balance sheet as of the beginning of the year of initial application, except for certain changes that require prospective adoption. The main provisions of the guidance require: (i) equity investments to be measured at fair value, with changes in fair value recognized in net income, unless the equity method is applied or the equity investments do not have readily determinable fair values in which case a practical alternative may be elected; (ii) use of an exit price when measuring the fair value of financial instruments for disclosures; and (iii) separate presentation of financial assets and liabilities by measurement category and form of instrument on the balance sheet or in the accompanying notes. The Company does not expect this guidance will have a material impact on its financial statements and EPS. ASU 2016-02, “Leases (Topic 842),” amends the accounting for leases by lessees and lessors. The primary change from the new guidance is the recognition of right-of-use assets and lease liabilities by lessees for those leases classified as operating leases. Additional changes include accounting for lease origination and executory costs, required lessee reassessments during the lease term due to changes in circumstances, and expanded lease disclosures. ASU 2016-02 will become effective January 1, 2019, with early adoption permitted, and requires entities to apply the new guidance using a modified retrospective transition. Modified retrospective transition requires entities to apply the new guidance as of the beginning of the earliest comparative period presented in the financial statements in which the entity first applies the new standard. Certain transition relief is permitted if elected by the entity. The adoption of ASU 2016-02 will result in the Company recognizing a right-of-use asset and lease liability on the consolidated balance sheet based on the present value of remaining operating lease payments (see Note 14 of the Company’s 2016 Form 10-K for the undiscounted future annual minimum rental commitments for operating leases). The Company does not expect this guidance will have a material impact on its EPS. ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” provides new guidance for recognizing impairment of most debt instruments measured at amortized cost, including loans and held to maturity (HTM) debt securities. The new guidance will require estimating current expected credit losses (CECL) over the remaining life of an instrument or a portfolio of instruments with similar risk characteristics based on relevant information about past events, current conditions, and reasonable forecasts. The initial estimate of, and the subsequent changes in, CECL will be recognized as credit loss expense through current earnings and will be reflected as an allowance for credit losses offsetting the carrying value of the financial instrument(s) on the balance sheet. The new guidance also amends the OTTI model for AFS debt securities by requiring the use of an allowance, rather than directly reducing the carrying value of the security, and eliminating consideration of the length of time such security has been in an unrealized loss position as a factor in concluding whether a credit loss exists. ASU 2016-13 will become effective January 1, 2020, with early adoption permitted as of January 1, 2019. The new guidance will be applied through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the entity applies the new guidance except that a prospective transition is required for AFS debt securities for which an OTTI had been recognized before the effective date. The Company is currently evaluating the impact of this guidance on its financial statements and EPS. ASU 2017-08, “Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities,” shortens the amortization period for the premium on certain callable debt securities to the earliest call date. The amendments are applicable to any purchased individual debt security with an explicit and noncontingent call feature that is callable at a fixed price on a preset date. The amendments do not impact the accounting for callable debt securities held at a discount. ASU 2017-08 will become effective on January 1, 2019, with early adoption permitted including in an interim period. The amendments will be applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. The Company is currently evaluating the impact of adopting this guidance on its financial statements and EPS.
