Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These unaudited condensed consolidated financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the interim 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. The unaudited condensed consolidated financial statements do not include all information and notes necessary for a complete presentation of results of income, comprehensive income, financial position, and cash flows in conformity with generally accepted accounting principles in the United States of America (“GAAP”). Accordingly, these 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, 2015 , contained in the Company’s Annual Report on Form 10-K as filed with the SEC. The Company’s significant accounting policies are included in Note 2 . Summary of Significant Accounting Policies , in the Company’s audited consolidated financial statements and the related notes for the year ended December 31, 2015 . There have been no significant changes to these accounting policies during the first three months of 2016 . Consolidation These unaudited condensed consolidated financial statements include the accounts of LPLFH and its subsidiaries. Intercompany transactions and balances have been eliminated. Equity investments in which the Company exercises significant influence but does not exercise control and is not the primary beneficiary are accounted for using the equity method. Use of Estimates The preparation of the unaudited condensed consolidated financial statements in conformity with GAAP requires the Company to make estimates and judgments that affect the reported amounts of assets and liabilities, revenue and expenses, and related disclosures of contingent assets and liabilities. These estimates are based on the information that is currently available and on various other assumptions that the Company believes to be reasonable under the circumstances. Actual results could vary from these estimates. Reportable Segment Management has determined that the Company operates in one segment, given the similar characteristics between our operations and the common nature of our products and services, production and distribution processes, and regulatory environment. Fair Value of Financial Instruments The Company’s financial assets and liabilities are carried at fair value or at amounts that, because of their short-term nature, approximate current fair value, with the exception of its held-to-maturity securities and indebtedness. The Company carries its held-to-maturity securities and indebtedness at amortized cost. The Company measures the implied fair value of its debt instruments using trading levels obtained from a third-party service provider. Accordingly, the debt instruments qualify as Level 2 fair value measurements. See Note 3 . Fair Value Measurements , for additional detail regarding the Company’s fair value measurements. As of March 31, 2016 , the carrying amount and fair value of the Company’s indebtedness was approximately $2,210.6 million and $2,179.0 million , respectively. As of December 31, 2015 , the carrying amount and fair value was approximately 2,215.0 million and $2,200.0 million , respectively. Recently Issued Accounting Pronouncements In December 2015, the Company early adopted Accounting Standards Update ("ASU") 2015-03, Interest—Imputation of Interest , which simplifies the presentation of debt issuance costs on the balance sheet by presenting debt issuance costs as a direct deduction from the carrying amount of the related debt liability. Debt issuance and amendment costs have been capitalized and are being amortized as additional interest expense over the expected terms of the related debt agreements. Interest costs incurred while obtaining the revolving credit facility are included in other assets and subsequently amortized ratably over the term of the revolving credit facility, regardless of whether there are any outstanding borrowings on the revolving credit facility. The adoption of ASU 2015-03 did not have a material impact on the Company's condensed consolidated financial statements. In August 2015, the Financial Accounting Standards Board ("FASB") issued ASU 2015-14, Revenue From Contracts with Customers (Topic 606) , Deferral of the Effective Date, which defers the effective date of ASU 2014-09, Revenue from Contracts with Customers (Topic 606) to January 1, 2018 for the Company, with early adoption permitted as of January 1, 2017. The new guidance requires either a retrospective or a modified retrospective approach to adoption. The Company is currently evaluating the available transition methods and the potential impact on its consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU 2016-02, Leases , which replaces the existing guidance in ASC 840, Leases . The new standard establishes a right-of-use model that requires a lessee to record a right-of-use asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the statement of operations. The guidance will be effective for the Company on January 1, 2019, and early adoption is permitted. The Company is currently evaluating the impact that ASU 2016-02 will have on its consolidated financial statements and results of operations. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606) , Principal versus Agent Considerations (Reporting Revenue Gross versus Net ), which clarifies the implementation guidance on principal versus agent considerations. The guidance includes indicators to assist an entity in determining whether it controls a specified good or service before it is transferred to the customers. The FASB will permit early adoption of the standard, but not before the original effective date of December 15, 2016. The Company is currently evaluating the impact that ASU 2016-08 will have on its consolidated financial statements and results of operations. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which affects entities that issue share-based payment awards to their employees. The ASU is designed to identify areas for simplification involving several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. The guidance will be effective for the Company on January 1, 2017, and early adoption is permitted in any interim or annual period. The Company is currently evaluating the impact that ASU 2016-09 will have on its consolidated financial statements and results of operations.

Fair Value Measurements

Fair Value Measurements	3 Months Ended
	Mar. 31, 2016
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 under current market conditions. 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 three months ended March 31, 2016 . 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 March 31, 2016 , 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. Examples of these securities include money market funds, U.S. treasury obligations, mutual funds, certificates of deposit, and traded equity and debt securities. 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 March 31, 2016 , 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; (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; and (3) cash flow hedges, which are measured using quoted prices for similar cash flow hedges, taking into account counterparty credit risk and the Company's own non-performance risk. 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 an income approach whereby the Company assesses the expected future performance of the acquired assets. The contingent payment is estimated using a discounted cash flow of the expected payment amount to calculate the fair value as of the valuation date. The Company then discounts these expected payment amounts 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 following table summarizes the Company’s financial assets and financial liabilities measured at fair value on a recurring basis at March 31, 2016 (in thousands): Level 1 Level 2 Level 3 Total Assets Cash equivalents $ 127,228 $ — $ — $ 127,228 Securities owned — trading: Money market funds 396 — — 396 Mutual funds 6,901 — — 6,901 Equity securities 575 — — 575 Debt securities — 176 — 176 U.S. treasury obligations 4,310 — — 4,310 Total securities owned — trading 12,182 176 — 12,358 Other assets 113,204 2,081 — 115,285 Total assets at fair value $ 252,614 $ 2,257 $ — $ 254,871 Liabilities Securities sold, but not yet purchased: Mutual funds $ 30 $ — $ — $ 30 Equity securities 201 — — 201 Debt securities — 48 — 48 Total securities sold, but not yet purchased 231 48 — 279 Accounts payable and accrued liabilities — — 527 527 Total liabilities at fair value $ 231 $ 48 $ 527 $ 806 The following table summarizes the Company’s financial assets and financial liabilities measured at fair value on a recurring basis at December 31, 2015 (in thousands): Level 1 Level 2 Level 3 Total Assets Cash equivalents $ 252,393 $ — $ — $ 252,393 Securities owned — trading: Money market funds 261 — — 261 Mutual funds 7,267 — — 7,267 Equity securities 56 — — 56 Debt securities — 103 — 103 U.S. treasury obligations 4,308 — — 4,308 Total securities owned — trading 11,892 103 — 11,995 Other assets 99,962 3,350 — 103,312 Total assets at fair value $ 364,247 $ 3,453 $ — $ 367,700 Liabilities Securities sold, but not yet purchased: Mutual funds $ 1 $ — $ — $ 1 Equity securities 267 — — 267 Total securities sold, but not yet purchased 268 — — 268 Accounts payable and accrued liabilities — — 527 527 Total liabilities at fair value $ 268 $ — $ 527 $ 795

Investments, Debt and Equity Securities [Abstract]
Held-to-Maturity Securities	Held-to-Maturity Securities The Company holds certain investments in securities, primarily U.S. government notes, which are recorded at amortized cost because the Company has both the intent and the ability to hold these investments to maturity. Interest income is accrued as earned. Premiums and discounts are amortized using a method that approximates the effective yield method over the term of the security and are recorded as an adjustment to the investment yield. The amortized cost, gross unrealized gain or loss, and fair value of securities held-to-maturity were as follows (in thousands): March 31, December 31, Amortized cost $ 7,847 $ 9,847 Gross unrealized gain (loss) 20 (26 ) Fair value $ 7,867 $ 9,821 At March 31, 2016 , the securities held-to-maturity were scheduled to mature as follows (in thousands): Within one year After one but within five years After five but within ten years Total U.S. government notes — at amortized cost $ 3,998 $ 3,349 $ 500 $ 7,847 U.S. government notes — at fair value $ 4,000 $ 3,352 $ 515 $ 7,867

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments In May 2013, in conjunction with its Service Value Commitment initiative, the Company entered into a long-term contractual obligation (the “Agreement”) with a third-party provider to enhance the quality, speed, and cost of processes by outsourcing certain functions. The Agreement enables the third-party provider to use the services of its affiliates in India to provide services to the Company and provides for the Company to settle the cost of its contractual obligation to the third-party provider in U.S. dollars each month. However, the Agreement provides that on each annual anniversary date of the signing of the Agreement, the price for services (denominated in U.S. dollars) is to be adjusted for the then-current exchange rate between the U.S. dollar (“USD”) and the Indian rupee (“INR”). The Agreement provides that once an annual adjustment is calculated, there are no further modifications to the amounts paid by the Company to the third-party provider for fluctuations in the exchange rate between the USD and the INR until the reset on the next anniversary date of the signing of the Agreement. The third-party provider bore the risk of currency movement from the date of signing the Agreement until the reset on the first anniversary of its signing, and bears such risk during each period until the next annual reset date. The Company bears the risk of currency movement at each of the annual reset dates following the first anniversary. To mitigate foreign currency risk arising from these annual reset events, the Company entered into four non-deliverable foreign currency contracts, all of which have been designated as cash flow hedges. The first cash flow hedge, with a notional amount of 560.4 million INR, or $8.5 million , settled in June 2014. The Company received a settlement of $1.0 million , which was reclassified out of accumulated other comprehensive income and was recognized in net income ratably over the 12-month period ending May 31, 2015 to match the timing of the underlying hedged item. The second cash flow hedge, with a notional amount of 560.4 million INR, or $8.1 million , settled in June 2015. The Company received a settlement of $0.7 million , which will be reclassified out of accumulated other comprehensive income and recognized in net income ratably over a 12-month period ending May 31, 2016 to match the timing of the underlying hedged item. The details related to the remaining non-deliverable foreign currency contracts at March 31, 2016 are as follows (in millions, except foreign exchange rate): Settlement Date Hedged Notional Amount (INR) Contractual INR/USD Foreign Exchange Rate Hedged Notional Amount (USD) Cash flow hedge #3 6/2/2016 560.4 72.21 7.8 Cash flow hedge #4 6/2/2017 560.4 74.20 7.5 Total hedged amount $ 15.3 The fair value of the derivative instruments, which are included in other assets in the unaudited condensed consolidated statements of financial condition, were as follows (in thousands): March 31, December 31, Cash flow hedges $ 1,004 $ 741

The Company’s outstanding borrowings as of the dates below were as follows (dollars in thousands): March 31, 2016 December 31, 2015 Senior Secured Credit Facilities Maturity Balance Interest Rate Balance Interest Rate Senior secured term loans: Term Loan A 9/30/2019 459,375 2.93 % (1) 459,375 2.74 % 2019 Term Loan B 3/29/2019 423,584 3.25 % (2) 424,676 3.25 % 2021 Term Loan B 3/29/2021 629,409 4.25 % (3) 630,986 4.25 % 2022 Term Loan B 11/20/2022 698,250 4.75 % (4) 700,000 4.75 % Total borrowings 2,210,618 2,215,037 Less Unamortized Debt Issuance Cost 25,575 26,797 Long-term borrowings — net of unamortized debt issuance cost $ 2,185,043 $ 2,188,240 _____________________ (1) The variable interest rate per annum is either (a) 150 bps over the base rate or (b) 250 bps over the LIBOR rate (subject to a leverage based grid) (2) The variable interest rate per annum is either (a) 150 bps over the base rate or (b) 250 bps over the LIBOR rate (subject to a LIBOR floor of 75 bps ) (3) The variable interest rate per annum is either (a) 250 bps over the base rate or (b) 350 bps over the LIBOR rate (subject to a LIBOR floor of 75 bps ) (4) The variable interest rate per annum is either (a) 300 bps over the base rate or (b) 400 bps over the LIBOR rate (subject to a LIBOR floor of 75 bps ) The Company also has a revolving credit facility with borrowing capacity of $400.0 million maturing on September 30, 2019. As of March 31, 2016 , the Company also had $18.0 million of irrevocable letters of credit, with an applicable interest rate margin of 2.50% , which were supported by the Company's revolving credit facility. The Credit Agreement subjects the Company to certain financial and non-financial covenants. As of March 31, 2016 , the Company was in compliance with such covenants. Bank Loans Payable The Company maintains three uncommitted lines of credit. Two of the lines have unspecified limits, which are primarily dependent on the Company’s ability to provide sufficient collateral. The third line has a $200 million limit, and allows for both collateralized and uncollateralized borrowings. The lines were not utilized during the three months ended March 31, 2016 or 2015 . There were no balances outstanding at March 31, 2016 or December 31, 2015 .

Commitments and Contingencies

Commitments and Contingencies	3 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Leases The Company leases office space and equipment under various operating leases. These leases are generally subject to scheduled base rent and maintenance cost increases, which are recognized on a straight-line basis over the period of the leases. Total rental expense for all operating leases was approximately $6.2 million and $6.6 million for the three months ended March 31, 2016 and 2015 , respectively. 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. The Company also has contractual obligations related to the development of a real estate project in Fort Mill, South Carolina for office space. Under development and agency contracts the Company expects to pay a pro rata share equal to 27.5% of the design and construction costs. The remaining amounts will be paid by the landlord. The Company’s share of these costs is expected to be approximately $74.7 million , incurred through 2017. Additionally, the Company has entered into lease agreements for the office space once developed. These leases have an initial lease term of 20 years that commence once the development is complete and the Company takes occupancy of the buildings. Guarantees The Company occasionally enters into certain types of 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. The Company’s subsidiary, 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 may 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 such significant unfunded commitments at March 31, 2016 . Legal & 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 can include fines and other remediation costs. Assessing the probability of a loss occurring and the 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, except as otherwise covered by third-party insurance or self-insurance through its captive insurance subsidiary, as discussed below. A putative class action lawsuit has been filed against the Company and certain of its executive officers in federal district court alleging certain misstatements and omissions related to the Company’s share repurchases and financial performance in late 2015. The Company intends to defend vigorously against the lawsuit. Third-Party Insurance The Company maintains third-party insurance coverage for certain potential legal proceedings, including those involving client claims. With respect to client claims, the estimated losses on many of the pending matters are less than the applicable deductibles of the insurance policies. Self-Insurance Liabilities The Company has self-insurance for certain potential liabilities, including various errors and omissions liabilities, through a wholly-owned 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. As of March 31, 2016 , these self-insurance liabilities are included in accounts payable and accrued liabilities in the unaudited condensed consolidated balance sheet. Self-insurance related charges are included in other expenses in the unaudited condensed consolidated statements of income for the three months ended March 31, 2016 . Other Commitments As of March 31, 2016 , the Company had approximately $219.9 million of client margin loans that were collateralized with securities having a fair value of approximately $307.9 million that it can re-pledge, loan, or sell. Of these securities, approximately $32.7 million were client-owned securities pledged to the Options Clearing Corporation as collateral to secure client obligations related to options positions. As of March 31, 2016 there were no restrictions that materially limited the Company's ability to re-pledge, loan, or sell the remaining $275.2 million of client collateral. Trading securities on the unaudited condensed consolidated statements of financial condition includes $4.3 million and $4.3 million pledged to clearing organizations at March 31, 2016 and December 31, 2015 , respectively. The Company is involved in a build-to-suit lease arrangement in Fort Mill, South Carolina, under which it serves as the construction agent on behalf of the landlord. Under such arrangement, the Company has obligations to fund cost over-runs in its capacity as the construction agent, and accordingly has determined that under lease accounting standards it bears substantially all of the risks and rewards of ownership as measured under GAAP. The Company is therefore required to report the landlord's costs of construction on its balance sheet as a fixed asset during the construction period as if the Company owned such asset. As of March 31, 2016 , the Company has recorded $74.8 million in fixed assets in connection with this arrangement and an equal and off-setting leasehold financing obligation on the unaudited condensed consolidated statement of financial condition.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stockholders' Equity	Share-Based Compensation Certain employees, advisors, institutions, officers, and directors of the Company participate in various long-term incentive plans, which provide for granting stock options, warrants, restricted stock awards, and restricted stock units. Stock options and warrants outstanding generally vest in equal increments over a three - to five -year period and expire on the ten th anniversary following the date of grant. Restricted stock awards and restricted stock units outstanding generally vest over a one - to four -year period. In November 2010, the Company adopted a 2010 Omnibus Equity Incentive Plan (as amended and restated in May 2015, the “2010 Plan”), which provides for the granting of stock options, warrants, restricted stock awards, restricted stock units, and other equity-based compensation. The 2010 Plan serves as the successor to the 2005 Stock Option Plan for Incentive Stock Options, the 2005 Stock Option Plan for Non-qualified Stock Options, the 2008 Advisor and Institution Incentive Plan, the 2008 Stock Option Plan, and the Director Restricted Stock Plan (collectively, the “Predecessor Plans”). Upon adoption of the 2010 Plan, awards were no longer made under the Predecessor Plans; however, awards previously granted under the Predecessor Plans remain outstanding until exercised or forfeited. There were 20,055,945 shares authorized for grant under the 2010 Plan after the amendment and restatement of the plan in May 2015. There were 7,239,782 shares reserved for issuance upon exercise or conversion of outstanding awards granted, and 9,883,553 shares remaining available for future issuance under the 2010 Plan as of March 31, 2016 .

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 is as follows (in thousands, except per share data): Three Months Ended March 31, 2016 2015 Net income $ 50,392 $ 50,678 Basic weighted-average number of shares outstanding 88,964 96,551 Dilutive common share equivalents 657 1,676 Diluted weighted-average number of shares outstanding 89,621 98,227 Basic earnings per share $ 0.57 $ 0.52 Diluted earnings per share $ 0.56 $ 0.52 The computation of diluted earnings per share excludes stock options, warrants, and restricted stock units that are anti-dilutive. For the three months ended March 31, 2016 and 2015 , stock options, warrants, and restricted stock units representing common share equivalents of 4,885,765 shares and 1,595,614 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 35.0% , primarily as a result of state taxes, settlement contingencies, and expenses that are not deductible for tax purposes. These items resulted in effective tax rates of 40.4% and 40.1% for the three months ended March 31, 2016 and 2015 . Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

Brokers and Dealers [Abstract]
Net Capital and Regulatory Requirements	Net Capital and Regulatory Requirements The Company operates in a highly regulated industry. Applicable laws and regulations restrict permissible activities and investments and require compliance with various financial and customer-related regulations. The consequences of noncompliance can include substantial monetary and non-monetary sanctions. In addition, the Company is also subject to comprehensive examinations and supervision by various governmental and self-regulatory agencies. These regulatory agencies generally have broad discretion to prescribe greater limitations on the operations of a regulated entity for the protection of investors or public interest. Furthermore, where the agencies determine that such operations are unsafe or unsound, fail to comply with applicable law, or are otherwise inconsistent with the laws and regulations or with the supervisory policies, greater restrictions may be imposed. The Company’s registered broker-dealer, LPL Financial, is subject to the SEC’s Uniform Net Capital Rule (Rule 15c3-1 under the Exchange Act), which requires the maintenance of minimum net capital, as defined. Net capital and the related net capital requirement may fluctuate on a daily basis. LPL Financial is a clearing broker-dealer and had net capital of $110.7 million with a minimum net capital requirement of $5.9 million as of March 31, 2016 . The Company's subsidiary, PTC, 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 to PTC's operations. As of March 31, 2016 and December 31, 2015 , 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, collateralized by cash or 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 three 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, as, and if issued securities. When, as, and if 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 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.

Summary of Significant Accoun24

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2016
Accounting Policies [Abstract]
Consolidation	Consolidation These unaudited condensed consolidated financial statements include the accounts of LPLFH and its subsidiaries. Intercompany transactions and balances have been eliminated. Equity investments in which the Company exercises significant influence but does not exercise control and is not the primary beneficiary are accounted for using the equity method.
Use of Estimates	Use of Estimates The preparation of the unaudited condensed consolidated financial statements in conformity with GAAP requires the Company to make estimates and judgments that affect the reported amounts of assets and liabilities, revenue and expenses, and related disclosures of contingent assets and liabilities. These estimates are based on the information that is currently available and on various other assumptions that the Company believes to be reasonable under the circumstances. Actual results could vary from these estimates.
Reportable Segment	Reportable Segment Management has determined that the Company operates in one segment, given the similar characteristics between our operations and the common nature of our products and services, production and distribution processes, and regulatory environment.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company’s financial assets and liabilities are carried at fair value or at amounts that, because of their short-term nature, approximate current fair value, with the exception of its held-to-maturity securities and indebtedness. The Company carries its held-to-maturity securities and indebtedness at amortized cost. The Company measures the implied fair value of its debt instruments using trading levels obtained from a third-party service provider. Accordingly, the debt instruments qualify as Level 2 fair value measurements. See Note 3 . Fair Value Measurements , for additional detail regarding the Company’s fair value measurements. As of March 31, 2016 , the carrying amount and fair value of the Company’s indebtedness was approximately $2,210.6 million and $2,179.0 million , respectively. As of December 31, 2015 , the carrying amount and fair value was approximately 2,215.0 million and $2,200.0 million , respectively.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In December 2015, the Company early adopted Accounting Standards Update ("ASU") 2015-03, Interest—Imputation of Interest , which simplifies the presentation of debt issuance costs on the balance sheet by presenting debt issuance costs as a direct deduction from the carrying amount of the related debt liability. Debt issuance and amendment costs have been capitalized and are being amortized as additional interest expense over the expected terms of the related debt agreements. Interest costs incurred while obtaining the revolving credit facility are included in other assets and subsequently amortized ratably over the term of the revolving credit facility, regardless of whether there are any outstanding borrowings on the revolving credit facility. The adoption of ASU 2015-03 did not have a material impact on the Company's condensed consolidated financial statements. In August 2015, the Financial Accounting Standards Board ("FASB") issued ASU 2015-14, Revenue From Contracts with Customers (Topic 606) , Deferral of the Effective Date, which defers the effective date of ASU 2014-09, Revenue from Contracts with Customers (Topic 606) to January 1, 2018 for the Company, with early adoption permitted as of January 1, 2017. The new guidance requires either a retrospective or a modified retrospective approach to adoption. The Company is currently evaluating the available transition methods and the potential impact on its consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU 2016-02, Leases , which replaces the existing guidance in ASC 840, Leases . The new standard establishes a right-of-use model that requires a lessee to record a right-of-use asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the statement of operations. The guidance will be effective for the Company on January 1, 2019, and early adoption is permitted. The Company is currently evaluating the impact that ASU 2016-02 will have on its consolidated financial statements and results of operations. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606) , Principal versus Agent Considerations (Reporting Revenue Gross versus Net ), which clarifies the implementation guidance on principal versus agent considerations. The guidance includes indicators to assist an entity in determining whether it controls a specified good or service before it is transferred to the customers. The FASB will permit early adoption of the standard, but not before the original effective date of December 15, 2016. The Company is currently evaluating the impact that ASU 2016-08 will have on its consolidated financial statements and results of operations. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which affects entities that issue share-based payment awards to their employees. The ASU is designed to identify areas for simplification involving several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. The guidance will be effective for the Company on January 1, 2017, and early adoption is permitted in any interim or annual period. The Company is currently evaluating the impact that ASU 2016-09 will have on its consolidated financial statements and results of operations.
