	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, 2013, 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 Annual Report on Form 10-K for the year ended December 31, 2013. There have been no significant changes to these accounting policies during the first six months of 2014.
	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 — The Company's internal reporting is organized into two service channels: Independent Advisor Services and Institution Services. These service channels qualify as individual operating segments and are aggregated and viewed as one reportable segment due to their similar economic characteristics, 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 indebtedness. The Company carries its 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 4. Fair Value Measurements, for additional detail regarding the Company’s fair value measurements. As of June 30, 2014, the carrying amount and fair value of the Company’s indebtedness was approximately $1,529.7 million and $1,523.9 million, respectively. As of December 31, 2013, the carrying amount and fair value was approximately $1,535.1 million and $1,533.3 million, respectively.
	Recently Issued Accounting Pronouncements
	In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360), which changes the requirements for reporting discontinued operations that may include a component of an entity or a group of components of an entity, or a business or nonprofit activity. A disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has, or will have, a major effect on an entity's operations and financial results when any of the following criteria is met with respect to the disposal: it can be classified as held for sale, disposed of by sale, or disposed of other than by sale (such as by abandonment, or in a distribution to owners in a spinoff). ASU 2014-08 will become effective for the Company beginning January 1, 2015. The Company does not anticipate that the adoption of ASU 2014-08 will have a material impact on its results of operations, financial condition, or cash flows.
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which completes the joint effort by the FASB and the International Accounting Standards Board to improve financial reporting by creating common revenue recognition guidance for GAAP and the International Financial Reporting Standards. ASU 2014-09 will become effective for the Company beginning January 1, 2017 and early adoption is not permitted. The Company is currently evaluating the potential impact of ASU 2014-09 on its consolidated financial statements.
	In June 2014, the FASB issued ASU 2014-12, Compensation—Stock Compensation (Topic 718), which requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. ASU 2014-12 will become effective for the Company beginning January 1, 2016 and early adoption is permitted. The Company does not anticipate that the adoption of ASU 2014-08 will have a material impact on its results of operations, financial condition, or cash flows.

	Restructuring
	In February 2013, the Company committed to an expansion of its Service Value Commitment (the “Program”), an ongoing effort to position the Company's people, processes, and technology for sustainable long-term growth while improving the service experience of its advisors and delivering efficiencies in its operating model. The Program is expected to be completed in 2015.
	The Company estimates total charges in connection with the Program will approach $65.0 million. These expenditures are comprised of outsourcing and other related costs, technology transformation costs, employee severance obligations and other related costs, and non-cash charges for impairment of certain fixed assets related to internally developed software.
	The following table summarizes the balance of accrued expenses and the changes in the accrued amounts for the Program as of and for the six months ended June 30, 2014 (in thousands):

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, 2014.
	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, 2014, 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 June 30, 2014, 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, 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.

	Changes in Level 3 Recurring Fair Value Measurements
	As of December 31, 2013, the Company had a contingent consideration obligation related to the acquisition of National Retirement Partners, Inc. (“NRP”). This obligation was based on the achievement of certain revenue-based targets for the twelve-month period ended November 30, 2013, in aggregate for those advisors joining LPL Financial LLC (“LPL Financial”) subsequent to the NRP acquisition for whom retirement plans comprise a significant part of their business. As of December 31, 2013, the Company had finalized the determination of the amount of contingent consideration to be paid to the former shareholders of NRP, resulting in a total payment of $39.3 million, which was made on February 19, 2014.
	The Company determines the fair value for its contingent consideration obligations using an income approach whereby the Company assesses the probability and timing of the achievement of the applicable milestones, which are based on contractually negotiated financial or operating targets that vary by acquisition transaction, such as revenues, gross margin, EBITDA, and assets under custody. The contingent payments are estimated using a probability weighted, multi-scenario analysis of expected future performance of the acquired businesses. 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 principal significant unobservable input used in the valuations of the Company's contingent consideration obligations is a risk-adjusted discount rate. Whereas management's underlying projections adjust for market penetration and adoption rates, the discount rate is risk-adjusted for key factors such as advisor attrition, advisor recruitment, expenses and overhead costs, average client assets, revenue generation of client assets, and credit risk. An increase in the discount rate will result in a decrease in the fair value of contingent consideration. Conversely, a decrease in the discount rate will result in an increase in the fair value of contingent consideration.

	In May 2013, in conjunction with its commitment to expand its Service Value Commitment, 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 anniversary 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 that will be reclassified out of accumulated other comprehensive income and recognized in net income to match the timing of the underlying hedged item.
	The details related to the remaining non-deliverable foreign currency contracts at June 30, 2014 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)

	Senior Secured Credit Facilities — On May 13, 2013, the Company entered into the First Amendment and Incremental Assumption Agreement (“Credit Agreement”) with its wholly owned subsidiary, LPL Holdings, Inc., and other parties thereto. The Credit Agreement amended the Company's previous credit agreement, which was dated March 29, 2012.
	The Credit Agreement includes a Term Loan A, a Term Loan B, and a revolving credit facility (“Revolving Credit Facility”). Term Loan A had an initial principal amount of $459.4 million maturing on March 29, 2017; Term Loan B had an initial principal amount of $1,083.9 million maturing on March 29, 2019; and the Revolving Credit Facility has a borrowing capacity of $250.0 million maturing on March 29, 2017.
	At the time the Company entered into the Credit Agreement, all mandatory payments required under Term Loan A were prepaid, with the remaining principal and accrued interest due upon maturity. Term Loan B includes quarterly payments at an annual rate of 1.0% of principal per year, with the remaining principal and accrued interest due upon maturity.
	Borrowings under Term Loan A and Term Loan B bear interest at a base rate equal to either one-, two-, three-, six-, nine-, or twelve-month LIBOR (the “Eurodollar Rate”) plus the applicable interest rate margin, or an alternative base rate (“ABR”) plus the applicable interest rate margin. The Eurodollar Rate with respect to Term Loan B shall in no event be less than 0.75%. The ABR is equal to the greatest of (a) the prime rate in effect on such day; (b) the effective federal funds rate in effect on such day plus 0.50%; (c) the Eurodollar Rate plus 1.00%; or (d) solely in the case of Term Loan B, 1.75%. The Company may repay outstanding loans under its Credit Agreement at any time without premium or penalty, other than customary “breakage” costs with respect to Eurodollar Rate loans.
	As of June 30, 2014, borrowings under the term loans bore interest at the Eurodollar Rate with an applicable interest rate margin of 2.50%. The Company’s outstanding borrowings were as follows (dollars in thousands):
				June 30, 2014								December 31, 2013

	-2	As of June 30, 2014, the Company elected the six-month LIBOR, which was less than 0.75%; as a result, the variable interest rate for Term Loan B was the minimum Eurodollar Rate of 0.75%.
	-3	As of December 31, 2013, the variable interest rate for Term Loan A was the one-month LIBOR, designated at an interest rate of 0.17%.
	-4	As of December 31, 2013, the Company elected the six-month LIBOR, which was less than 0.75%; as a result, the variable interest rate for Term Loan B was the minimum Eurodollar Rate of 0.75%.
	As of June 30, 2014, the Revolving Credit Facility was being used to support the issuance of $21.4 million of irrevocable letters of credit for the construction of the Company's San Diego office building and other items, with an applicable interest rate margin of 2.50%. An irrevocable letter of credit for $20.7 million matures on March 29, 2015, while the remaining letters totaling $0.7 million mature on various dates through June 8, 2015. The remaining available balance of $228.6 million was undrawn at June 30, 2014.
	The Credit Agreement subjects the Company to certain financial and non-financial covenants. As of June 30, 2014, 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 $200.0 million limit, and allows for both collateralized and uncollateralized borrowings. The lines have not been utilized in 2014, but were utilized in 2013; however, there were no balances outstanding at June 30, 2014 or December 31, 2013.
	The following summarizes borrowing activity in the revolving and uncommitted line of credit facilities (dollars in thousands):

	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 $8.2 million and $5.0 million for the three months ended June 30, 2014 and 2013, respectively, and $17.0 million and $10.0 million for the six months ended June 30, 2014 and 2013, respectively.
	In March 2014 the Company entered into a lease agreement for additional office space in Charlotte, North Carolina with a lease commencement date of March 1, 2014 and an expiration date of February 28, 2017. Future minimum payments for this lease commitment are $0.4 million, $1.0 million, $1.1 million, and $0.2 million, for the years 2014, 2015, 2016, and 2017, respectively.
	Service 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 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 unfunded 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 June 30, 2014.
	Disputed & Regulatory Matters — The Company maintains insurance coverage for certain client claims. With respect to these matters, the estimated losses on the majority of pending matters are less than the applicable deductibles of the insurance policies. The Company is also subject to extensive regulation and supervision by U.S. federal and state agencies and various self-regulatory organizations. The Company and its financial 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 restitution, fines, and other remedies. As of June 30, 2014, the Company believes, based on the information available at this time, consideration of amounts accrued, insurance, if any, and indemnifications provided by the third-party indemnitors, if any, that the outcomes of any such pending claims or matters with estimated losses in excess of applicable deductibles will not have a material impact on its unaudited condensed consolidated statements of income, financial condition, or cash flows.
	Certain former owners of Concord Capital Partners, Inc. (“CCP”), a subsidiary that the Company acquired in June 2011, have filed lawsuits with claims related to contingent consideration under the stock purchase agreement relating to the Company's acquisition of CCP and employment-related claims. As of June 30, 2014, after consideration of amounts accrued and applicable insurance, the Company does not believe that the outcomes of these matters, individually or in the aggregate, will have a material impact on its unaudited condensed consolidated statements of income, financial condition, or cash flows.
	Other Commitments — As of June 30, 2014, the Company had received collateral primarily in connection with client margin loans with a market value of approximately $383.2 million, which it can re-pledge, loan, or sell. Of these securities, approximately $31.3 million were client-owned securities pledged to the Options Clearing Corporation as collateral to secure client obligations related to options positions. Additionally, approximately $172.6 million was held at banks in connection with unutilized secured margin lines of credit; these securities may be used as collateral for loans from these banks. The remainder of $179.3 million had not been re-pledged, loaned, or sold, and as of June 30, 2014 there were no restrictions that materially limited the Company's ability to re-pledge, loan, or sell the remaining $351.9 million of client collateral.
	Trading securities on the unaudited condensed consolidated statements of financial condition includes $2.0 million and $1.4 million pledged to clearing organizations at June 30, 2014 and December 31, 2013, respectively.
	Brokerage, clearing, and custody services are provided by LPL Financial on a fully disclosed basis. LPL Financial also has a multi-year agreement to provide its investment advisory programs, platforms, technology, and additional processing and related services to the advisors of the broker-dealer subsidiary of a large global insurance company and the clients of such advisors at specified service levels. Failures by LPL Financial to meet certain specified service levels may result in service level credits against future fees payable by or give rise to a termination right for such broker-dealer. Termination fees may be payable by a terminating or breaching party depending on the specific cause of termination.

	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 generally vest in equal increments over a three- to five-year period and expire on the tenth anniversary following the date of grant. Restricted stock awards and restricted stock units generally vest over a two- to four-year period.
	On November 17, 2010, the Company adopted a 2010 Omnibus Equity Incentive Plan (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 are 12,055,945 shares authorized for grant under the 2010 Plan. As of June 30, 2014, there were 6,157,487 shares reserved for issuance upon exercise or conversion of outstanding awards granted under the 2010 Plan.

	The Company recognizes share-based compensation for stock options awarded to employees, officers, and directors based on the grant date fair value over the requisite service period of the award, which generally equals the vesting period. The Company recognized share-based compensation related to the vesting of these awards of $3.8 million and $3.8 million during the three months ended June 30, 2014 and 2013, respectively, and $7.6 million and $7.3 million during the six months ended June 30, 2014 and 2013, respectively, which is included in compensation and benefits expense on the unaudited condensed consolidated statements of income. As of June 30, 2014, total unrecognized compensation cost related to non-vested stock options granted to employees, officers and directors was $30.2 million, which is expected to be recognized over a weighted-average period of 2.45 years.

	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 three and six months ended June 30, 2014 and 2013 is as follows (in thousands, except per share data):
		Three Months Ended June 30,				Six Months Ended June 30,
		2014		2013		2014		2013
	Net income	$	43,091	$	45,091	$	96,226	$	99,808
	Basic weighted-average number of shares outstanding	100,244		106,414		100,756		106,381
	Dilutive common share equivalents	1,785		1,281		1,916		1,084
	Diluted weighted-average number of shares outstanding	102,029		107,695		102,672		107,465
	Basic earnings per share	$	0.43	$	0.42	$	0.96	$	0.94
	Diluted earnings per share	$	0.42	$	0.42	$	0.94	$	0.93
	The computation of diluted earnings per share excludes stock options, warrants, and restricted stock units that are anti-dilutive. For the three months ended June 30, 2014 and 2013, stock options, warrants, and restricted stock units representing common share equivalents of 1,510,813 shares and 3,864,493 shares, respectively, were anti-dilutive. For the six months ended June 30, 2014 and 2013, stock options, warrants, and restricted stock units representing common share equivalents of 1,282,968 shares and 4,689,047 shares, respectively, were anti-dilutive.

	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 39.4% and 39.8% for the three months ended June 30, 2014 and 2013, respectively, and 39.4% and 39.7% for the six months ended June 30, 2014 and 2013, respectively. 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.

	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 $187.5 million with a minimum net capital requirement of $6.8 million and net capital in excess of the minimum requirement of $180.7 million as of June 30, 2014.
	The Company's subsidiary, The Private Trust Company N.A. (“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 June 30, 2014 and December 31, 2013, LPL Financial and PTC met all capital adequacy requirements to which they were subject.

	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 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 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 Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2014
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 — The Company's internal reporting is organized into two service channels: Independent Advisor Services and Institution Services. These service channels qualify as individual operating segments and are aggregated and viewed as one reportable segment due to their similar economic characteristics, 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 indebtedness. The Company carries its 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 4. Fair Value Measurements, for additional detail regarding the Company’s fair value measurements. As of June 30, 2014, the carrying amount and fair value of the Company’s indebtedness was approximately $1,529.7 million and $1,523.9 million, respectively. As of December 31, 2013, the carrying amount and fair value was approximately $1,535.1 million and $1,533.3 million, respectively.
Recently Issued Accounting Pronouncements	'
	Recently Issued Accounting Pronouncements
	In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360), which changes the requirements for reporting discontinued operations that may include a component of an entity or a group of components of an entity, or a business or nonprofit activity. A disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has, or will have, a major effect on an entity's operations and financial results when any of the following criteria is met with respect to the disposal: it can be classified as held for sale, disposed of by sale, or disposed of other than by sale (such as by abandonment, or in a distribution to owners in a spinoff). ASU 2014-08 will become effective for the Company beginning January 1, 2015. The Company does not anticipate that the adoption of ASU 2014-08 will have a material impact on its results of operations, financial condition, or cash flows.
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which completes the joint effort by the FASB and the International Accounting Standards Board to improve financial reporting by creating common revenue recognition guidance for GAAP and the International Financial Reporting Standards. ASU 2014-09 will become effective for the Company beginning January 1, 2017 and early adoption is not permitted. The Company is currently evaluating the potential impact of ASU 2014-09 on its consolidated financial statements.
	In June 2014, the FASB issued ASU 2014-12, Compensation—Stock Compensation (Topic 718), which requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. ASU 2014-12 will become effective for the Company beginning January 1, 2016 and early adoption is permitted. The Company does not anticipate that the adoption of ASU 2014-08 will have a material impact on its results of operations, financial condition, or cash flows.

'

'

'

'

'

'Borrowings under Term Loan A and Term Loan B bear interest at a base rate equal to either one-, two-, three-, six-, nine-, or twelve-month LIBOR (the “Eurodollar Rate”) plus the applicable interest rate margin, or an alternative base rate (“ABR”) plus the applicable interest rate margin. The Eurodollar Rate with respect to Term Loan B shall in no event be less than 0.75%. The ABR is equal to the greatest of (a) the prime rate in effect on such day; (b) the effective federal funds rate in effect on such day plus 0.50%; (c) the Eurodollar Rate plus 1.00%; or (d) solely in the case of Term Loan B, 1.75%. The Company may repay outstanding loans under its Credit Agreement at any time without premium or penalty, other than customary “breakage” costs with respect to Eurodollar Rate loans.
