Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”), which require the Company to make estimates and assumptions regarding the valuation of certain financial instruments, intangible assets, allowance for doubtful accounts, share-based compensation, accruals for liabilities, income taxes, revenue and expense accruals, and other matters that affect the consolidated financial statements and related disclosures. The unaudited condensed consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary to present fairly the results for the interim periods presented. Actual results could differ from those estimates under different assumptions or conditions and the differences may be material to the consolidated financial statements. The unaudited condensed consolidated financial statements include the accounts of LPLFH and its subsidiaries. Intercompany transactions and balances have been eliminated. The unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the related notes for the year ended December 31, 2020, contained in the Company’s Annual Report on Form 10-K as filed with the Securities and Exchange Commission (“SEC”).

Revenue from Contract with Customer [Abstract]
Revenues	REVENUES Revenues are recognized when control of the promised services is transferred to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services. Revenues are analyzed to determine whether the Company is the principal (i.e., reports revenues on a gross basis) or agent (i.e., reports revenues on a net basis) in the contract. Principal or agent designations depend primarily on the control an entity has over the product or service before control is transferred to a customer. The indicators of which party exercises control include primary responsibility over performance obligations, inventory risk before the good or service is transferred and discretion in establishing the price. Advisory Advisory revenues represent fees charged to advisors’ clients’ accounts on the Company’s corporate advisory platform. The Company provides ongoing investment advice and acts as a custodian, providing brokerage and execution services on transactions, and performs administrative services for these accounts. This series of performance obligations transfers control of the services to the client over time as the services are performed. These revenues are recognized ratably over time to match the continued delivery of the performance obligations to the client over the life of the contract. The advisory revenues generated from the Company’s corporate RIA advisory platform are based on a percentage of the market value of the eligible assets in the clients’ advisory accounts. As such, the consideration for these revenues are variable and an estimate of the variable consideration is constrained due to dependence on unpredictable market impacts on client portfolio values. The constraint is removed once the portfolio value can be determined. The Company provides advisory services to clients on its corporate advisory platform through the advisor. The Company is the principal in these arrangements and recognizes advisory revenues on a gross basis, as the Company is responsible for satisfying the performance obligations and has control over determining the fees. Commission Commission revenues represent sales commissions generated by advisors for their clients’ purchases and sales of securities on exchanges and over-the-counter, as well as purchases of other investment products. The Company views the selling, distribution and marketing, or any combination thereof, of investment products to such clients as a single performance obligation to the product sponsors. The Company is the principal for commission revenues, as it is responsible for the execution of the clients’ purchases and sales, and maintains relationships with the product sponsors. Advisors assist the Company in performing its obligations. Accordingly, total commission revenues are reported on a gross basis. The following table presents total commission revenues disaggregated by investment product category (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 Commission revenues Annuities $ 305,100 $ 217,637 $ 585,876 $ 463,299 Mutual funds 195,688 133,800 368,838 289,956 Fixed income 34,862 18,463 67,024 47,588 Equities 30,517 27,985 69,428 65,406 Other 32,066 29,568 64,296 64,648 Total commission revenues $ 598,233 $ 427,453 $ 1,155,462 $ 930,897 The Company generates two types of commission revenues: sales-based commissions that are recognized at the point of sale on the trade date and trailing commissions that are recognized over time as earned. Sales-based commission revenues vary by investment product and are based on a percentage of an investment product’s current market value at the time of purchase. Trailing commission revenues are generally based on a percentage of the current market value of clients’ investment holdings in trail-eligible assets, and are recognized over the period during which services, such as ongoing support, are performed. As trailing commission revenues are based on the market value of clients’ investment holdings, the consideration is variable and an estimate of the variable consideration is constrained due to dependence on unpredictable market impacts. The constraint is removed once the investment holdings value can be determined. The following table presents sales-based and trailing commission revenues disaggregated by product category (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 Commission revenues Sales-based Annuities $ 112,619 $ 64,287 $ 208,158 $ 156,812 Mutual funds 50,250 29,716 97,529 75,250 Fixed income 34,862 18,463 67,024 47,588 Equities 30,517 27,985 69,428 65,406 Other 21,348 19,061 43,730 42,847 Total sales-based revenues $ 249,596 $ 159,512 $ 485,869 $ 387,903 Trailing Annuities $ 192,481 $ 153,350 $ 377,718 $ 306,487 Mutual funds 145,438 104,084 271,309 214,706 Other 10,718 10,507 20,566 21,801 Total trailing revenues $ 348,637 $ 267,941 $ 669,593 $ 542,994 Total commission revenues $ 598,233 $ 427,453 $ 1,155,462 $ 930,897 Asset-Based Asset-based revenues consist of fees from the Company’s client cash programs, which consist of fees from its money market program and insured bank sweep vehicles, sponsorship programs and recordkeeping. Client Cash Revenues Client cash revenues are generated based on advisors’ clients’ cash balances in insured bank sweep accounts and money market programs. The Company receives fees based on account type and invested balances for administration and recordkeeping. These fees are paid and recognized over time. Sponsorship Programs The Company receives fees from product sponsors, primarily mutual fund and annuity companies, for marketing support and sales force education and training efforts. Compensation for these performance obligations is either a fixed fee, a percentage of the average annual amount of product sponsor assets held in advisors’ clients’ accounts, a percentage of new sales or some combination. As the value of product sponsor assets held in advisors’ clients’ accounts is susceptible to unpredictable market changes, these revenues include variable consideration and are constrained until the date that the fees are determinable. Recordkeeping The Company generates revenues from fees it collects for providing recordkeeping, account maintenance, reporting and other related services to product sponsors. This includes revenues from omnibus processing in which the Company establishes and maintains sub-account records for its clients to reflect the purchase, exchange and redemption of mutual fund shares, and consolidates clients’ trades within a mutual fund. Omnibus processing fees are paid to the Company by the mutual fund or its affiliates and are based on the value of mutual fund assets in accounts for which the Company provides omnibus processing services and the number of accounts in which the related mutual fund positions are held. Recordkeeping revenues also include revenues from networking recordkeeping services. Networking revenues on brokerage assets are correlated to the number of positions or value of assets that the Company administers and are paid by mutual fund and annuity product manufacturers. These recordkeeping revenues are recognized over time as the Company fulfills its performance obligations. As recordkeeping fees are susceptible to unpredictable market changes that influence market value and fund positions, these revenues include variable consideration and are constrained until the date that the fees are determinable. Depending on the contract, the Company is either principal or agent for recordkeeping revenues. In instances in which the Company is providing services to financial product manufacturers on behalf of third parties and does not have ultimate control of the service before transfer to the customer, the Company is considered to be an agent and reports revenues on a net basis. In other cases, where the Company uses a sub-contractor to provide services and is responsible for unperformed services, the Company is considered principal and reports revenues on a gross basis. The following table sets forth asset-based revenues at a disaggregated level (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 Asset-based revenues Client cash $ 90,377 $ 116,266 $ 187,481 $ 267,664 Sponsorship programs 95,978 63,885 177,690 128,334 Recordkeeping 93,265 66,916 179,155 136,575 Total asset-based revenues $ 279,620 $ 247,067 $ 544,326 $ 532,573 Transaction and Fee Transaction revenues primarily include fees the Company charges to advisors and their clients for executing certain transactions in brokerage and fee-based advisory accounts. Transaction revenues are recognized at the point-in-time that a transaction is executed, which is generally the trade date. Fee revenues may be generated from advisors or their clients. Fee revenues primarily include IRA custodian fees, contract and licensing fees, and other client account fees. In addition, the Company hosts certain advisor conferences that serve as training, education, sales and marketing events, for which the Company collects a fee for attendance. Fee revenues are recognized when the Company satisfies its performance obligations. Recognition varies from point-in-time to over time depending on whether the service is provided once at an identifiable point-in-time or if the service is provided continually over the contract life. The following table sets forth transaction and fee revenues disaggregated by recognition pattern (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 Transaction and fee revenues Point-in-time (1) $ 61,526 $ 52,306 $ 127,339 $ 117,944 Over time (2) 75,574 67,172 150,705 138,630 Total transaction and fee revenues $ 137,100 $ 119,478 $ 278,044 $ 256,574 _______________________________ (1) Transaction and fee revenues recognized point-in-time include revenues such as transaction fees, IRA termination fees and technology fees. (2) Transaction and fee revenues recognized over time include revenues such as error and omission insurance fees, IRA custodian fees and technology fees. The Company is the principal and recognizes transaction and fee revenues on a gross basis as it is primarily responsible for delivering the respective services being provided, which is demonstrated by the Company’s ability to control the fee amounts charged to customers. Interest Income The Company earns interest income from client margin loans, advisor loans, cash segregated under federal and other regulations, and cash equivalents. Other Other revenues primarily include unrealized gains and losses on assets held by the Company for its advisor non-qualified deferred compensation plan and model research portfolios and other miscellaneous revenues. These revenues are not generated from contracts with customers. Unearned Revenue The Company records unearned revenue when cash payments are received or due in advance of the Company’s performance obligations, including amounts which are refundable. The increase in the unearned revenue balance for the six months ended June 30, 2021 is primarily driven by cash payments received or due in advance of satisfying the Company’s performance obligations, offset by $92.6 million o f revenues recognized that were included in the unearned revenue balance as of December 31, 2020. For advisory services, revenue is recognized as the Company provides the administration, brokerage and execution services over time to satisfy the performance obligations. For conference revenue, the Company recognizes revenue as the conferences are held.

Fair Value Measurements

Fair Value Measurements	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Inputs used to measure fair value are prioritized within a three-level fair value hierarchy. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: Level 1 — Quoted prices in active markets for identical assets or liabilities. Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. There have been no transfers of assets or liabilities between these fair value measurement classifications during the six months ended June 30, 2021 or June 30, 2020. The Company’s fair value measurements are evaluated within the fair value hierarchy, based on the nature of inputs used to determine the fair value at the measurement date. At June 30, 2021 and December 31, 2020, the Company had the following financial assets and liabilities that are measured at fair value on a recurring basis: Cash Equivalents — The Company’s cash equivalents include money market funds, which are short term in nature with readily determinable values derived from active markets. Securities Owned and Securities Sold, But Not Yet Purchased — The Company’s trading securities consist of house account model portfolios established and managed for the purpose of benchmarking the performance of its fee-based advisory platforms and temporary positions resulting from the processing of client transactions. The Company uses prices obtained from independent third-party pricing services to measure the fair value of its trading securities. Prices received from the pricing services are validated using various methods including comparison to prices received from additional pricing services, comparison to available quoted market prices and review of other relevant market data including implied yields of major categories of securities. In general, these quoted prices are derived from active markets for identical assets or liabilities. When quoted prices in active markets for identical assets and liabilities are not available, the quoted prices are based on similar assets and liabilities or inputs other than the quoted prices that are observable, either directly or indirectly. For certificates of deposit and treasury securities, the Company utilizes market-based inputs, including observable market interest rates that correspond to the remaining maturities or the next interest reset dates. At June 30, 2021, the Company did not adjust prices received from the independent third-party pricing services. Other Assets — The Company’s other assets include: (1) deferred compensation plan assets that are invested in money market and other mutual funds, which are actively traded and valued based on quoted market prices; and (2) certain non-traded real estate investment trusts and auction rate notes, which are valued using quoted prices for identical or similar securities and other inputs that are observable or can be corroborated by observable market data. Accounts Payable and Accrued Liabilities — The Company’s accounts payable and accrued liabilities include contingent consideration liabilities that are measured using Level 3 inputs. Level 3 Recurring Fair Value Measurements The Company determines the fair value for its contingent consideration obligations using a scenario-based approach whereby the Company assesses the expected number of future transactions. The contingent payment is estimated by applying a discount rate to the expected payment to calculate the fair value as of the valuation date. The Company’s management evaluates the underlying projections and other related factors used in determining fair value each period and makes updates when there have been significant changes in management’s expectations.

The fair value of receivables from clients, product sponsors, broker-dealers and clearing organizations, advisor loans and others, securities borrowed, drafts payable, payables to clients, broker-dealers and clearing organizations, and other payables were estimated to approximate carrying value and classified as Level 2 of the fair value hierarchy due to their short-term nature.

Issuance of 2031 Senior Notes LPLH raised $400.0 million in aggregate principal amount of 4.375% senior notes on May 18, 2021, which were issued at par (“2031 Senior Notes”). The Company used the proceeds from the issuance to repay borrowings made under the senior secured revolving credit facility related to the acquisition of the wealth management business of Waddell & Reed Financial, Inc. The 2031 Senior Notes are unsecured obligations, governed by an indenture, that will mature on May 15, 2031, and bear interest at the rate of 4.375% per year, with interest payable semi-annually. The Company may redeem all or part of the 2031 Senior Notes at any time prior to May 15, 2026 (subject to a customary “equity claw” redemption right) at 100% of the principal amount redeemed plus any accrued and unpaid interest thereon and a “make-whole” premium. Thereafter, the Company may redeem all or part of the 2031 Senior Notes at annually declining redemption premiums until May 15, 2029, at and after which date the redemption price will be equal to 100% of the principal amount redeemed plus any accrued and unpaid interest thereon. In connection with the issuance of the 2031 Senior Notes, the Company incurred $3.8 million in costs, which are capitalized as debt issuance costs in the unaudited condensed consolidated statements of financial condition. Issuance of 2029 Senior Notes LPLH raised $900.0 million in aggregate principal amount of 4.00% senior notes on March 15, 2021, which were issued at par (“2029 Senior Notes”). The company used the proceeds from the issuance of the 2029 Senior Notes, along with existing corporate cash available, to redeem the 2025 Senior Notes. In connection with this redemption, the Company recognized $24.4 million as a loss on extinguishment of debt on the unaudited condensed consolidated statements of income. The 2029 Senior Notes are unsecured obligations, governed by an indenture, that will mature on March 15, 2029, and bear interest at the rate of 4.00% per year, with interest payable semi-annually. The Company may redeem all or part of the 2029 Senior Notes at any time prior to March 15, 2024 (subject to a customary “equity claw” redemption right) at 100% of the principal amount redeemed plus any accrued and unpaid interest thereon and a “make-whole” premium. Thereafter, the Company may redeem all or part of the 2029 Senior Notes at annually declining redemption premiums until March 15, 2026, at and after which date the redemption price will be equal to 100% of the principal amount redeemed plus any accrued and unpaid interest thereon. In connection with the issuance of the 2029 Senior Notes, the Company incurred $9.0 million in costs, which are capitalized as debt issuance costs in the unaudited condensed consolidated statements of financial condition. Credit Agreement On March 15, 2021, LPLFH and LPLH entered into a fifth amendment agreement (the “Amendment”) to the Company’s amended and restated credit agreement (“Credit Agreement”), which, among other things, increased the size of its senior secured revolving credit facility to $1.0 billion and extended the maturity date of its senior secured revolving credit facility. In connection with the execution of the Amendment, the Company incurred $3.2 million in costs, which are capitalized as debt issuance costs in the unaudited condensed consolidated statements of financial condition. The Credit Agreement subjects the Company to certain financial and non-financial covenants. As of June 30, 2021, the Company was in compliance with such covenants. Parent Revolving Credit Facility Borrowings under the revolving credit facility bear interest at a rate per annum ranging from 125 to 175 basis points over the Eurodollar Rate or 25 to 75 basis points over the base rate, depending on the Consolidated Secured Debt to Consolidated EBITDA Ratio (as defined in the Credit Agreement). Broker-Dealer Revolving Credit Facility On July 31, 2019, LPL Financial, the Company’s broker-dealer subsidiary, entered into a committed, unsecured revolving credit facility that matures on July 31, 2024 and allows for a maximum borrowing of $300.0 million. Borrowings bear interest at a rate per annum ranging from 112.5 to 137.5 basis points over the Federal Funds Rate or Eurodollar Rate, depending on the Parent Leverage Ratio (each as defined in the broker-dealer credit agreement). The broker-dealer credit agreement subjects LPL Financial to certain financial and non-financial covenants with which LPL Financial was in compliance as of June 30, 2021.

Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Service and Development Contracts The Company is party to certain long-term contracts for systems and services that enable back-office trade processing and clearing for its product and service offerings. Guarantees The Company occasionally enters into contracts that contingently require it to indemnify certain parties against third-party claims. The terms of these obligations vary and, because a maximum obligation is not explicitly stated, the Company has determined that it is not possible to make an estimate of the amount that it could be obligated to pay under such contracts. LPL Financial provides guarantees to securities clearing houses and exchanges under their standard membership agreements, which require a member to guarantee the performance of other members. Under these agreements, if a member becomes unable to satisfy its obligations to the clearing houses and exchanges, all other members would be required to meet any shortfall. The Company’s liability under these arrangements is not quantifiable and could exceed the cash and securities it has posted as collateral. However, the potential requirement for the Company to make payments under these agreements is remote. Accordingly, no liability has been recognized for these transactions. Loan Commitments From time to time, LPL Financial makes loans to its advisors, primarily to newly recruited advisors to assist in the transition process, which may be forgivable. Due to timing differences, LPL Financial may make commitments to issue such loans prior to actually funding them. These commitments are generally contingent upon certain events occurring, including but not limited to the advisor joining LPL Financial. LPL Financial had no significant unfunded loan commitments at June 30, 2021. Legal and Regulatory Matters The Company is subject to extensive regulation and supervision by U.S. federal and state agencies and various self-regulatory organizations. The Company and its advisors periodically engage with such agencies and organizations, in the context of examinations or otherwise, to respond to inquiries, informational requests and investigations. From time to time, such engagements result in regulatory complaints or other matters, the resolution of which has in the past and may in the future include fines, customer restitution and other remediation. Assessing the probability of a loss occurring and the timing and amount of any loss related to a legal proceeding or regulatory matter is inherently difficult. While the Company exercises significant and complex judgments to make certain estimates presented in its consolidated financial statements, there are particular uncertainties and complexities involved when assessing the potential outcomes of legal proceedings and regulatory matters. The Company’s assessment process considers a variety of factors and assumptions, which may include: the procedural status of the matter and any recent developments; prior experience and the experience of others in similar matters; the size and nature of potential exposures; available defenses; the progress of fact discovery; the opinions of counsel and experts; potential opportunities for settlement and the status of any settlement discussions; as well as the potential for insurance coverage and indemnification, if available. The Company monitors these factors and assumptions for new developments and re-assesses the likelihood that a loss will occur and the estimated range or amount of loss, if those amounts can be reasonably determined. The Company has established an accrual for those legal proceedings and regulatory matters for which a loss is both probable and the amount can be reasonably estimated. Third-Party Insurance The Company maintains third-party insurance coverage for certain potential legal proceedings, including those involving certain client claims. With respect to such client claims, the estimated losses on many of the pending matters are less than the applicable deductibles of the insurance policies. Self-Insurance The Company has self-insurance for certain potential liabilities through the Captive Insurance Subsidiary. Liabilities associated with the risks that are retained by the Company are not discounted and are estimated by considering, in part, historical claims experience, severity factors and other actuarial assumptions. The estimated accruals for these potential liabilities could be significantly affected if future occurrences and claims differ from such assumptions and historical trends, so there are particular complexities and uncertainties involved when assessing the adequacy of loss reserves for potential liabilities that are self-insured. As of June 30, 2021 and December 31, 2020, these self-insurance liabilities were $64.0 million and $51.5 million , respectively, and are included in accounts payable and accrued liabilities in the unaudited condensed consolidated statements of financial condition. Self-insurance related charges are included in other expenses in the unaudited condensed consolidated statements of income. Other Commitments As of June 30, 2021, the Company had approxi mate ly $455.8 million of cl ient margin loans that were collateralized with securities having a fair value of approximatel y $638.2 million t hat LPL Financial can repledge, loan or sell. Of these securities, approximate ly $72.9 million were client-owned securities pledged to the Options Clearing Corporation as collateral to secure client obligations related to options positions. As of June 30, 2021, there were no restrictions that materially limited the Company’s ability to repledge, loan or sell the remainin g $565.3 million of client collateral.

Repurchased shares are included in treasury stock on the unaudited condensed consolidated statements of financial condition. As of June 30, 2021, the Company was authorized to purchase up to an additional $349.8 million of shares pursuant to share repurchase programs approved by the Board of Directors. The Company expects to restart its share repurchase program during the third quarter of 2021 with an initial focus on repurchases to offset dilution, which we expect will result in repurchases of approximately $40.0 million per quarter.

Share-based Payment Arrangement [Abstract]
Stockholders' Equity	SHARE-BASED COMPENSATION In May 2021, the Company adopted the 2021 Omnibus Equity Incentive Plan (the “2021 Plan”), which provides for the granting of stock options, warrants, restricted stock awards, restricted stock units, deferred stock units, performance stock units and other equity-based compensation to the Company’s employees, non-employee directors and other service providers. The 2021 Plan serves as the successor to the Company’s 2010 Omnibus Equity Incentive Plan (the “2010 Plan”). Following the adoption of the 2021 Plan, the Company is no longer making grants under the 2010 Plan, and the 2021 Plan is the only plan under which equity awards are granted. However, awards previously granted under the 2010 Plan will remain outstanding until vested, exercised or forfeited, as applicable. There were 17,754,197 shares authorized for grant under the 2021 Plan and 14,707,051 shares remaining available for future issuance at June 30, 2021.

Earnings Per Share [Abstract]
Earnings per Share	EARNINGS PER SHARE Basic earnings per share is computed by dividing net income available to common stockholders by the weighted-average number of shares of common stock outstanding during the period. The computation of diluted earnings per share is similar to the computation of basic earnings per share, except that the denominator is increased to include the number of additional shares of common stock that would have been outstanding if dilutive potential shares of common stock had been issued. The calculation of basic and diluted earnings per share for the periods noted was as follows (in thousands, except per share data): Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 Net income $ 119,101 $ 101,662 $ 248,721 $ 257,303 Basic weighted-average number of shares outstanding 80,063 78,940 79,880 79,223 Dilutive common share equivalents 1,665 1,187 1,728 1,436 Diluted weighted-average number of shares outstanding 81,728 80,127 81,608 80,659 Basic earnings per share $ 1.49 $ 1.29 $ 3.11 $ 3.25 Diluted earnings per share $ 1.46 $ 1.27 $ 3.05 $ 3.19 The computation of diluted earnings per share excludes stock options, warrants and stock units that are anti-dilutive. For the three months ended June 30, 2020, stock options, warrants and stock units representing common share equivalents of 1,040,297 shares were anti-dilutive. There were no such anti-dilutive shares during the three months ended June 30, 2021. For the six months ended June 30, 2021 and 2020, stock options, warrants and stock units representing common share equivalents of 2,604 shares and 683,813 shares, respectively, were anti-dilutive.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The Company’s effective income tax rate differs from the federal corporate tax rate of 21.0%, primarily as a result of state taxes, settlement contingencies, tax credits and other permanent differences in tax deductibility of certain expenses. These items resulted in effective tax rates of 26.3% and 25.9% for the three months ended June 30, 2021 and 2020, respectively, and 23.9% and 25.4% for the six months ended June 30, 2021 and 2020, respectively.

Net Capital and Regulatory Requ

Brokers and Dealers [Abstract]
Net Capital and Regulatory Requirements	NET CAPITAL AND REGULATORY REQUIREMENTS The Company’s registered broker-dealer, LPL Financial, is subject to the SEC’s Net Capital Rule (Rule 15c3-1 under the Exchange Act), which requires the maintenance of minimum net capital. The net capital rules also provide that the broker-dealer’s capital may not be withdrawn if the resulting net capital would be less than minimum requirements. Additionally, certain withdrawals require the approval of the SEC and FINRA to the extent they exceed defined levels, even though such withdrawals would not cause net capital to be less than minimum requirements. Net capital and the related net capital requirement may fluctuate on a daily basis. LPL Financial is a clearing broker-dealer and, as of June 30, 2021, had net capital of $140.8 million, which was $127.5 million in excess of its minimum net capital requirement of $13.3 million. In April 2021, the Company acquired a broker-dealer as part of its acquisition of the wealth management business of Waddell & Reed Financial, Inc. (the “Waddell & Reed broker-dealer”). The Waddell & Reed broker-dealer is required to maintain net capital of $250,000, which represents the greater of 2% of its aggregate debits or the minimum net capital requirement of $250,000. At June 30, 2021, the Waddell & Reed broker-dealer had net capital of $21.6 million, which was $21.3 million in excess of its minimum capital requirement. The Company expects to dissolve the Waddell & Reed broker-dealer during the fourth quarter of 2021. The Company’s subsidiary, PTC, also operates in a highly regulated industry and is subject to various regulatory capital requirements. Failure to meet minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have substantial monetary and non-monetary impacts on PTC’s operations. As of June 30, 2021 and December 31, 2020, LPL Financial and PTC met all capital adequacy requirements to which they were subject.

Concentration Risk Credit Risk Financial Instruments Off Balance Sheet Risk [Abstract]
Financial Instruments with Off-Balance-Sheet Credit Risk and Concentrations of Credit Risk	FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET CREDIT RISK AND CONCENTRATIONS OF CREDIT RISK LPL Financial’s client securities activities are transacted on either a cash or margin basis. In margin transactions, LPL Financial extends credit to the advisor’s client, subject to various regulatory and internal margin requirements, which is collateralized by cash and securities in the client’s account. As clients write options contracts or sell securities short, LPL Financial may incur losses if the clients do not fulfill their obligations and the collateral in the clients’ accounts is not sufficient to fully cover losses that clients may incur from these strategies. To control this risk, LPL Financial monitors margin levels daily and clients are required to deposit additional collateral, or reduce positions, when necessary. LPL Financial is obligated to settle transactions with brokers and other financial institutions even if its advisors’ clients fail to meet their obligation to LPL Financial. Clients are required to complete their transactions on the settlement date, generally two business days after the trade date. If clients do not fulfill their contractual obligations, LPL Financial may incur losses. In addition, the Company occasionally enters into certain types of contracts to fulfill its sale of when-issued securities. When-issued securities have been authorized but are contingent upon the actual issuance of the security. LPL Financial has established procedures to reduce this risk by generally requiring that clients deposit cash or securities into their account prior to placing an order. LPL Financial may at times hold equity securities on both a long and short basis that are recorded on the unaudited condensed consolidated statements of financial condition at market value. While long inventory positions represent LPL Financial’s ownership of securities, short inventory positions represent obligations of LPL Financial to deliver specified securities at a contracted price, which may differ from market prices prevailing at the time of completion of the transaction. Accordingly, both long and short inventory positions may result in losses or gains to LPL Financial as market values of securities fluctuate. To mitigate the risk of losses, long and short positions are marked-to-market daily and are continuously monitored by LPL Financial.

Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”), which require the Company to make estimates and assumptions regarding the valuation of certain financial instruments, intangible assets, allowance for doubtful accounts, share-based compensation, accruals for liabilities, income taxes, revenue and expense accruals, and other matters that affect the consolidated financial statements and related disclosures. The unaudited condensed consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary to present fairly the results for the interim periods presented. Actual results could differ from those estimates under different assumptions or conditions and the differences may be material to the consolidated financial statements. The unaudited condensed consolidated financial statements include the accounts of LPLFH and its subsidiaries. Intercompany transactions and balances have been eliminated. The unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the related notes for the year ended December 31, 2020, contained in the Company’s Annual Report on Form 10-K as filed with the Securities and Exchange Commission (“SEC”).
