Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Critical Accounting Policies The Company's critical accounting policies and estimates are disclosed in its Annual Report on Form 10-K for the year ended December 31, 2018 . The Company believes that the disclosures herein are adequate so that the information presented is not misleading; however, these financial statements should be read in conjunction with the financial statements and the notes thereto in the Company's Annual Report on Form 10-K for the year ended December 31, 2018 . The financial data for the interim periods may not necessarily be indicative of results for future interim periods or for the full year. Changes to the Company's accounting policies as a result of adoption ASU 2016-02, Leases (Topic 842) are discussed under "Leases" below and in Note 8. Basis of Presentation The accompanying unaudited consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and related rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for interim financial reporting and include all adjustments, consisting only of normal recurring adjustments which are, in the opinion of management, necessary for a fair statement of the results for the interim period. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates or assumptions that affect the reported amounts and disclosures in the consolidated financial statements. Actual results could differ from these estimates or assumptions. Principles of Consolidation The Company consolidates all majority-owned subsidiaries. In addition, as of March 31, 2019 , Manning & Napier holds an economic interest of approximately 18.6% in Manning & Napier Group but, as managing member, controls all of the business and affairs of Manning & Napier Group. As a result, the Company consolidates the financial results of Manning & Napier Group and records a noncontrolling interest on its consolidated statements of financial condition with respect to the remaining economic interest in Manning & Napier Group held by Manning & Napier Group Holdings, LLC (“M&N Group Holdings”) and Manning & Napier Capital Company, LLC (“MNCC”). All material intercompany transactions have been eliminated in consolidation. In accordance with Accounting Standards Update ("ASU") 2015-02, Consolidation (Topic 810) – Amendments to the Consolidation Analysis , the determination of whether a company is required to consolidate an entity is based on, among other things, an entity’s purpose and design, a company’s ability to direct the activities of the entity that most significantly impact the entity’s economic performance, and whether a company is obligated to absorb losses or receive benefits that could potentially be significant to the entity. The standard also requires ongoing assessments of whether a company is the primary beneficiary of a variable interest entity (“VIE”). When utilizing the voting interest entity ("VOE") model, controlling financial interest is generally defined as majority ownership of voting interests. The Company provides seed capital to its investment teams to develop new strategies and services for its clients. The original seed investment may be held in a separately managed account, comprised solely of the Company's investments or within a mutual fund, where the Company's investments may represent all or only a portion of the total equity investment in the mutual fund. Pursuant to U.S. GAAP, the Company evaluates its investments in mutual funds on a regular basis and consolidates such mutual funds for which it holds a controlling financial interest. When no longer deemed to hold a controlling financial interest, the Company would deconsolidate the fund and classify the remaining investment as either an equity method investment or as trading securities, as applicable. The Company serves as the investment adviser for Manning & Napier Fund, Inc. series of mutual funds (the “Fund”), Exeter Trust Company Collective Investment Trusts (“CIT”) and Rainier Multiple Investment Trust. The Fund, CIT and Rainier Multiple Investment Trust are legal entities, the business and affairs of which are managed by their respective boards of directors. As a result, each of these entities is a VOE. The Company holds, in limited cases, direct investments in a mutual fund (which are made on the same terms as are available to other investors) and consolidates each of these entities where it has a controlling financial interest or a majority voting interest. The Company's investments in the Fund amounted to approximately $3.9 million as of March 31, 2019 and $3.6 million as of December 31, 2018 . As of March 31, 2019 and December 31, 2018 the Company did not have a controlling financial interest in any mutual fund. Revenue Investment Management: Investment management fees are computed as a percentage of assets under management ("AUM"). The Company's performance obligation is a series of services that form part of a single performance obligation satisfied over time. Separately managed accounts are paid in advance, typically for a semi-annual or quarterly period, or in arrears, typically for a monthly or quarterly period. When investment management fees are paid in advance, the Company defers the revenue as a contract liability and recognizes it over the applicable period. When investment management fees are paid in arrears, the Company estimates revenue and records a contract asset (accrued accounts receivable) based on AUM as of the most recent month end date. Mutual funds and collective investment trust investment management revenue is calculated and earned daily based on AUM. Revenue is presented net of cash rebates and fees waived pursuant to contractual expense limitations of the funds. The Company also has agreements with third parties who provide recordkeeping and administrative services for employee benefit plans participating in the collective investment trusts. The Company is acting as an agent on behalf of the employee benefit plan sponsors, therefore, investment management revenue is recorded net of fees paid to third party service providers. Distribution and shareholder servicing: The Company receives distribution and servicing fees for providing services to its affiliated mutual funds. Revenue is computed and earned daily based on a percentage of AUM. The performance obligation is a series of services that form part of a single performance obligation satisfied over time. The Company has agreements with third parties who provide distribution and administrative services for its mutual funds. The agreements are evaluated to determine whether revenue should be reported gross or net of payments to third-party service providers. The Company controls the services provided and acts as a principal in the relationship. Therefore, distribution and shareholder servicing revenue is recorded gross of fees paid to third parties. Custodial services: Custodial service fees are calculated as a percentage of the client’s market value with additional fees charged for certain transactions. For the safeguarding and administrative services that are subject to a percentage of market value fee, the Company's performance obligation is a series of services that form part of a single performance obligation satisfied over time. Revenue for transactions assigned a stand-alone selling price is recognized in the period which the transaction is executed. Custodial service fees are billed monthly in arrears. The Company has agreements with third parties who provide safeguarding, recordkeeping and administrative services for their clients. The Company controls the services provided and acts as a principal in the relationship. Therefore, custodial service revenue is recorded gross of fees paid to third parties. Costs to Obtain a Contract Incremental first year commissions directly associated with new separate account and collective investment trust contracts are capitalized and amortized on a straight-line basis over the estimated customer contract period of 7 years for separate accounts and 3 years for collective investment trust contracts. Refer to Note 3 for further discussion. Cash and Cash Equivalents The Company generally considers all highly liquid investments with original maturities of three months or less to be cash equivalents. Cash and cash equivalents are primarily held in operating accounts at major financial institutions and also in money market securities. Cash equivalents are stated at cost, which approximates market value due to the short-term maturity of these investments. The fair value of cash equivalents have been classified as Level 1 in accordance with the fair value hierarchy. Investment Securities Investment securities are classified as either trading, equity method investments or available-for-sale and are carried at fair value. Fair value is determined based on quoted market prices in active markets for identical or similar instruments. Investment securities classified as trading consist of equity securities, fixed income securities, and investments in mutual funds for which the Company provides advisory services. Realized and unrealized gains and losses on trading securities are recorded in net gains (losses) on investments in the consolidated statements of operations. At March 31, 2019 , trading securities consist of investments held by the Company to provide initial cash seeding for product development purposes and investments to hedge economic exposure to market movements on its deferred compensation plan. Investments classified as equity method investments represent seed investments in which the Company owns between 20-50% of the outstanding voting interests in the affiliated fund or when it is determined that the Company is able to exercise significant influence but not control over the investments. If the seed investment results in significant influence, but not control, the investment will be accounted for as an equity method investment. When using the equity method, the Company recognizes its share of the investee's net income or loss for the period which is recorded in net gains (losses) on investments in the consolidated statements of operations. Investment securities classified as available-for-sale consist of U.S. Treasury notes and other short-term investments. Unrealized gains and losses on available-for-sale securities are excluded from earnings and are reported, net of deferred income tax, as a separate component of accumulated other comprehensive income in stockholders’ equity until realized. The Company periodically reviews each individual security position that has an unrealized loss, or impairment, to determine if that impairment is other-than-temporary. If impairment is determined to be other-than-temporary, the carrying value of the security will be written down to fair value and the loss will be recognized in earnings. Realized gains and losses on sales of available-for-sale securities are computed on a specific identification basis and are recorded in net gains (losses) on investments in the consolidated statements of operations. Property and Equipment Property and equipment is presented net of accumulated depreciation of approximately $11.2 million and $11.3 million as of March 31, 2019 and December 31, 2018 , respectively. Goodwill and Intangible Assets Goodwill represents the excess cost over the fair value of the identifiable net assets of acquired companies. Identifiable intangible assets generally represent the cost of client relationships and investment management agreements acquired as well as trademarks. Goodwill and indefinite-lived assets are tested for impairment annually or more frequently if events or circumstances indicate that the carrying value may not be recoverable. Intangible assets subject to amortization are tested for impairment whenever events or circumstances indicate that the carrying value may not be recoverable. Goodwill and intangible assets require significant management estimate and judgment, including the valuation and expected life determination in connection with the initial purchase price allocation and the ongoing evaluation for impairment. Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use ("ROU") assets, accrued expenses and other liabilities and operating lease liabilities, non-current on its consolidated statements of financial condition. Finance leases are included in other long-term assets, accrued expenses and other liabilities, and other long-term liabilities on its consolidated statements of financial condition. ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The incremental borrowing rate, for each identified lease, is the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term. The operating lease ROU asset is reduced for any lease incentives. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that it will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are combined for all classes of underlying assets. Operating Segments The Company operates in one segment, the investment management industry. Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which is intended to increase transparency and comparability among organizations by recognizing all lease transactions (with terms in excess of 12 months) on the balance sheet as a lease liability and a right-of-use asset (as defined). In July 2018, the FASB issued ASU 2018-11, Leases - Targeted Improvements , which provides an optional transition method related to implementing the new lease standard. The Company adopted the new standard on its effective date of January 1, 2019. Refer to Note 8 for further discussion regarding the impact of adoption. In February 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income . The ASU requires a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the newly enacted federal corporate income tax rate as a result of the Tax Cuts and Jobs Act. The amount of the reclassification is the difference between the historical corporate income tax rate and the newly enacted 21% corporate income tax rate. The ASU will be effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company's adoption of ASU 2018-02 on January 1, 2019 did not have a material impact on its consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment , which simplifies the accounting for goodwill impairments by eliminating step two from the goodwill impairment test. The ASU requires goodwill impairments to be measured on the basis of the fair value of the reporting unit relative to the reporting unit's carrying amount rather than on the basis of the implied amount of goodwill relative to the goodwill balance of the reporting unit. The ASU is effective for annual and interim impairment tests for periods beginning after December 15, 2019. Early adoption is allowed for annual and interim impairment tests occurring after January 1, 2017. The Company is evaluating the effect of adopting this new accounting standard.

Noncontrolling Interest [Abstract]
Noncontrolling Interests	Noncontrolling Interests Manning & Napier holds an economic interest of approximately 18.6% in Manning & Napier Group, but as managing member controls all of the business and affairs of Manning & Napier Group. As a result, the Company consolidates the financial results of Manning & Napier Group and records a noncontrolling interest on its consolidated statement of financial condition with respect to the remaining approximately 81.4% economic interest in Manning & Napier Group held by M&N Group Holdings and MNCC. Net income attributable to noncontrolling interests on the statements of operations represents the portion of earnings attributable to the economic interest in Manning & Napier Group held by the noncontrolling interests. The following provides a reconciliation from “Income before provision for income taxes” to “Net income attributable to Manning & Napier, Inc.”: Three months ended March 31, 2019 2018 (in thousands) Income before provision for income taxes $ 3,159 $ 7,751 Less: income before provision for income taxes of Manning & Napier, Inc.

(2) Income before provision for income taxes is allocated to the controlling interest based on the percentage of units of Manning & Napier Group held by Manning & Napier, Inc. The amount represents the Company's weighted ownership of Manning & Napier Group for the respective periods. (3) The consolidated provision for income taxes is equal to the sum of (i) the provision for income taxes for entities other than Manning & Napier, Inc. and (ii) the provision for income taxes of Manning & Napier, Inc. which includes all U.S. federal and state income taxes. The consolidated provision for income taxes was $0.2 million and $0.5 million for the three months ended March 31, 2019 and 2018 , respectively. As of March 31, 2019 , a total of 63,349,721 units of Manning & Napier Group were held by the noncontrolling interests. Pursuant to the terms of the exchange agreement entered into at the time of the Company's initial public offering ("Exchange Agreement"), such units may be exchangeable for shares of the Company's Class A common stock. For any units exchanged, the Company will (i) pay an amount of cash equal to the number of units exchanged multiplied by the value of one share of the Company's Class A common stock less a market discount and expected expenses, or, at the Company's election, (ii) issue shares of the Company's Class A common stock on a one-for-one basis, subject to customary adjustments. As the Company receives units of Manning & Napier Group that are exchanged, the Company's ownership of Manning & Napier Group will increase. See Note 14 for further discussion. During the three months ended March 31, 2019 , Class A common stock was issued under the Company's 2011 Equity Compensation Plan (the "Equity Plan") for which Manning & Napier, Inc. acquired an equivalent number of Class A units of Manning & Napier Group, net of forfeitures of unvested restricted stock awards. The following is the impact to the Company's equity ownership interest in Manning & Napier Group for the three months ended March 31, 2019 : Manning & Napier Group Class A Units Held Manning & Napier Total Manning & Napier Ownership % As of December 31, 2018 14,126,736 63,349,721 77,476,457 18.2% Class A Units issued 351,532 — 351,532 0.4% Class A Units exchanged — — — —% As of March 31, 2019 14,478,268 63,349,721 77,827,989 18.6% Since the Company continues to have a controlling interest in Manning & Napier Group, the aforementioned changes in ownership of Manning & Napier Group were accounted for as equity transactions under ASC 810, Consolidation . Additional paid-in capital and noncontrolling interests in the Consolidated Statements of Financial Position are adjusted to reallocate the Company's historical equity to reflect the change in ownership of Manning & Napier Group. At March 31, 2019 and December 31, 2018 , the Company had recorded a liability of $17.8 million and $18.0 million , respectively, representing the estimated payments due to the selling unit holders under the tax receivable agreement ("TRA") entered into between Manning & Napier and the other holders of Class A Units of Manning & Napier Group. Of these amounts, $0.7 million were included in accrued expenses and other liabilities at both March 31, 2019 and December 31, 2018 . The Company made no payments pursuant to the TRA during the three months ended March 31, 2019 and 2018 . Obligations pursuant to the TRA are obligations of Manning & Napier. They do not impact the noncontrolling interests. These obligations are not income tax obligations. Furthermore, the TRA has no impact on the allocation of the provision for income taxes to the Company’s net income.

Fair value is determined based on quoted market prices in active markets for identical or similar instruments. Investment securities classified as trading consist of equity securities, fixed income securities and investments in mutual funds for which the Company provides advisory services. At March 31, 2019 and December 31, 2018 , trading securities consist of investments held by the Company to provide initial cash seeding for product development purposes and investments in mutual funds to hedge economic exposure to market movements on its deferred compensation plan. The Company recognized approximately $0.9 million of net unrealized gains and $0.2 million of net unrealized losses related to investments classified as trading during the three months ended March 31, 2019 and 2018 , respectively. Investment securities classified as available-for-sale consist of U.S. Treasury notes, corporate bonds and other short-term investments to optimize cash management opportunities and for compliance with certain regulatory requirements. As of March 31, 2019 and December 31, 2018 , approximately $0.6 million of these securities was considered restricted. The Company periodically reviews each individual security position that has an unrealized loss, or impairment, to determine if that impairment is other-than-temporary. No other-than-temporary impairment charges have been recognized by the Company during the three months ended March 31, 2019 and 2018 .

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that the Company would receive upon selling an investment in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. A fair value hierarchy is provided that gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The following three-tier fair value hierarchy prioritizes the inputs used in measuring fair value: • Level 1—observable inputs such as quoted prices in active markets for identical securities; • Level 2—other significant observable inputs (including but not limited to quoted prices for similar securities, interest rates, prepayment rates, credit risk, etc.); and • Level 3—significant unobservable inputs (including the Company’s own assumptions in determining the fair value of investments). The following provides the hierarchy of inputs used to derive the fair value of the Company’s assets as of March 31, 2019 and December 31, 2018 : March 31, 2019 Level 1 Level 2 Level 3 Totals (in thousands) Equity securities $ 5,242 $ — $ — $ 5,242 Fixed income securities — 17,926 — 17,926 Mutual funds 3,864 — — 3,864 U.S. Treasury notes — 17,651 — 17,651 Short-term investments 40,225 3,198 — 43,423 Total assets at fair value $ 49,331 $ 38,775 $ — $ 88,106 Contingent consideration liability $ — $ — $ — $ — Total liabilities at fair value $ — $ — $ — $ — December 31, 2018 Level 1 Level 2 Level 3 Totals (in thousands) Equity securities $ 4,683 $ — $ — $ 4,683 Fixed income securities — 15,413 — 15,413 Mutual funds 3,566 — — 3,566 U.S. Treasury notes — 21,649 — 21,649 Short-term investments 43,914 1,965 — 45,879 Total assets at fair value $ 52,163 $ 39,027 $ — $ 91,190 Contingent consideration liability $ — $ — $ — $ — Total liabilities at fair value $ — $ — $ — $ — Short-term investments consists of certificate of deposits that are stated at cost, which approximate fair value due to the short maturity of the investments and U.S. Treasury bills. Valuations of investments in fixed income securities and U.S. Treasury notes and bills can generally be obtained through independent pricing services. For most bond types, the pricing service utilizes matrix pricing, which considers one or more of the following factors: yield or price of bonds of comparable quality, coupon, maturity, current cash flows, type and current day trade information, as well as dealer supplied prices. These valuations are categorized as Level 2 in the hierarchy. Contingent consideration was a component of the purchase price of Rainier in 2016 of additional cash payments of up to $32.5 million over the period ending December 31, 2019, contingent upon Rainier's achievement of certain financial targets. The fair value of the contingent consideration is calculated on a quarterly basis by forecasting Rainier’s adjusted earnings before interest, taxes and amortization over the contingency period. There were no changes in contingent consideration liability measured at fair value using significant unobservable inputs (Level 3) for the three months ended March 31, 2019 . The Company’s policy is to recognize transfers in and transfers out of the valuation levels as of the beginning of the reporting period. There were no transfers between valuation levels during the three months ended March 31, 2019 .

Employees electing to participate in the offering were subject to approval by the Company, and received enhanced separation benefits. These employees are required to render service until their agreed upon termination date (which varies from person to person) in order to receive the benefits and as such, the liability will be recognized ratably over the applicable service period. The Company estimates the total employee severance costs under the offering to be approximately $2.6 million , of which approximately $2.2 million was recognized during the year ended December 31, 2018 . During the three months ended March 31, 2019 , the Company recognized approximately $0.1 million of severance costs under the offering and approximately $0.4 million as a result of involuntary workforce reductions. Employee severance costs recognized are included in compensation and related costs in the consolidated statements of operations.

Leases [Abstract]
Leases	Leases Adoption of ASU 2016-02, Leases (Topic 842) On January 1, 2019, the Company adopted Topic 842 using the optional transition method. Consequently, financial information and disclosures for the reporting periods beginning after January 1, 2019 are presented under Topic 842, while prior period amounts are not adjusted and continue to be reported in accordance with the Company's historic accounting policies under Topic 840. Topic 842 provides a number of optional practical expedients as part of the transition from Topic 840. The Company elected the ‘package of practical expedients’, which permits it to not reassess, under Topic 842, its prior conclusions about lease identification, lease classification and initial direct costs. Topic 842 also provides practical expedients for an entity’s ongoing accounting under Topic 842. The Company elected the short-term lease recognition exemption for all leases that qualify, and elected the practical expedient to combine lease and non-lease components as a single combined lease component for all of its leases. On adoption, the Company recognized lease liabilities of approximately $23.2 million and right-of-use assets for approximately $20.6 million , based on the present value of the remaining minimum rental payments under Topic 840 for operating leases that existed as of the date of adoption. In addition, the Company wrote-down approximately $2.6 million of unamortized deferred lease costs and tenant incentives previously recorded as deferred rent liability in the consolidated statements of financial condition as of December 31, 2018. The Company recognized an increase to opening shareholders' equity and noncontrolling interest of approximately $0.1 million , as of January 1, 2019, related to the deferred tax impacts of adopting Topic 842. Leases The Company has operating and finance leases for office space and certain equipment. For these leases, the office space or equipment is an explicitly identified asset within the contract. The Company has determined that it has obtained substantially all of the economic benefits from the use of the underlying asset and directs how and for what purpose the asset is used during the term of the contract. The Company's leases have remaining lease terms ranging between 1 year and approximately 9 years. The Company's lease term on certain of its multi-year office space leases, including its headquarters, include options for the Company to extend those leases for periods ranging from an additional five to ten years. In addition, the Company has the option to reduce a portion of its square footage at certain times throughout the term of the lease for its headquarters. The Company determined it is not reasonably certain at this time it will exercise the options to extend these leases or will exercise the options to reduce its square footage; therefore, the payment amounts related to these lease term extensions and contraction options have been excluded from determining its right-of-use asset and lease liability. Certain of the Company's operating leases for office space include variable lease payments, including non-lease components (such as utilities and operating expenses) that vary based on actual expenses and are adjusted on an annual basis. The Company concluded that these variable lease payments are in substance fixed payments and included the estimated variable payments in its determination of right-of-use assets and lease liabilities. Changes in the lease terms, including renewal options and options to reduce its square footage, incremental borrowing rates, and/or variable lease payments, and the corresponding impact to the right-of-use assets and lease liabilities, are recognized in the period incurred. Certain of the Company's operating leases have been subleased for which the Company will receive cash totaling approximately $0.4 million over the term of such leases. The lease terms for the two subleased operating leases end in 2019 and 2021. The components of lease expense for the three months ended March 31, 2019 were as follows: Three months ended March 31, 2019 (in thousands) Finance lease expense Amortization of right-of-use assets $ 29 Interest on lease liabilities 3 Operating lease expense 923 Short-term lease expense 4 Variable lease expense 46 Sublease income (123 ) Total $ 882 Supplemental cash flow information related to leases for the three months ended March 31, 2019 was as follows: Three months ended March 31, 2019 (in thousands) Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from finance leases $ 3 Finance cash flows from finance leases $ 27 Operating cash flows from operating leases $ 794 Right-of-use assets obtained in exchange for new lease obligations: Finance leases $ 163 Operating leases $ — Supplemental balance sheet information related to leases as of March 31, 2019 was as follows: (in thousands, except lease term and discount rate) March 31, 2019 Finance Leases Finance lease right-of-use assets (1) $ 284 Accrued expenses and other liabilities $ 127 Other long-term liabilities 173 Total finance lease liabilities $ 300 Operating Leases Operating lease right-of-use assets $ 19,957 Accrued expenses and other liabilities $ 2,722 Operating lease liabilities, non-current 20,010 Total operating lease liabilities $ 22,732 Weighted average remaining lease term Finance leases 3.10 years Operating leases 8.03 years Weighted average discount rate Finance leases 4.27 % Operating leases 5.21 % _______________________ (1) Amounts included in other long-term assets within the consolidated statements of financial condition.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies The Company may from time to time enter into agreements that contain certain representations and warranties and which provide general indemnifications. The Company may also serve as a guarantor of such obligations. The Company’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Company that have not yet occurred. The Company expects any risk of liability associated with such guarantees to be remote. Regulation As an investment adviser to a variety of investment products, the Company and its affiliated broker-dealer are subject to routine reviews and inspections by the SEC and the Financial Industry Regulatory Authority, Inc. Additionally, the Company could be subject to non-routine reviews and inspections by the National Futures Association and U.S. Commodity Futures Trading Commission in regards to the Company’s de minimis exposure to commodity interest investments in the mutual funds and collective investment trust vehicles it operates. From time to time the Company may also be subject to claims, or be involved in various legal proceedings, arising in the ordinary course of its business and other contingencies. The Company does not believe that the outcome of any of these reviews, inspections or other legal proceedings will have a material impact on its consolidated financial statements; however, litigation is subject to many uncertainties, and the outcome of individual litigated matters is difficult to predict. The Company will establish accruals for matters that are probable, can be reasonably estimated, and may take into account any related insurance recoveries to the extent of such recoveries. As of March 31, 2019 and December 31, 2018 , the Company has not accrued for any such claims, legal proceedings, or other contingencies.

Earnings per Common Share

Earnings Per Share [Abstract]
Earnings per Common Share	Earnings per Common Share Basic earnings per share (“basic EPS”) is computed using the two-class method to determine net income available to Class A common stock. The two-class method includes an earnings allocation formula that determines earnings per share for each participating security according to dividends declared and undistributed earnings for the period. The Company's restricted Class A common shares granted under the Equity Plan have non-forfeitable dividend rights during their vesting period and are therefore considered participating securities under the two-class method. Under the two-class method, the Company's net income available to Class A common stock is reduced by the amount allocated to the unvested restricted Class A common stock. Basic EPS is calculated by dividing net income available to Class A common stock by the weighted average number of common shares outstanding during the period. Diluted earnings per share (“diluted EPS”) is computed under the more dilutive of either the treasury method or the two-class method. For the diluted calculation, the weighted average number of common shares outstanding during the period is increased by the assumed conversion into Class A common stock of the unvested equity awards and the exchangeable Class A units of Manning & Napier Group, to the extent that such conversion would dilute earnings per share. The following is a reconciliation of the income and share data used in the basic and diluted EPS computations for the three months ended March 31, 2019 and 2018 under the two-class method: Three months ended March 31, 2019 2018 (in thousands, except share data) Net income attributable to controlling and noncontrolling interests $ 2,917 $ 7,273 Less: net income attributable to noncontrolling interests 2,356 6,059 Net income attributable to Manning & Napier, Inc. $ 561 $ 1,214 Less: allocation to participating securities (5 ) 63 Net income available to Class A common stock $ 566 $ 1,151 Weighted average shares of Class A common stock outstanding - basic 14,927,265 14,313,549 Dilutive effect of unvested equity awards 304,183 51,888 Dilutive effect of exchangeable Class A Units 63,349,721 63,918,146 Weighted average shares of Class A common stock outstanding - diluted 78,581,169 78,283,583 Net income available to Class A common stock per share - basic $ 0.04 $ 0.08 Net income available to Class A common stock per share - diluted $ 0.03 $ 0.07 For the three-months ended March 31, 2019 , 3,000,000 unvested performance-based stock options were excluded from the calculation of diluted EPS because the associated market condition had not yet been achieved. For the three-months ended March 31, 2019 and 2018 , 1,413,560 and 866,103 , respectively, unvested equity awards were excluded from the calculation of diluted EPS because the effect would have been anti-dilutive.

Share-based Compensation [Abstract]
Equity Based Compensation	Equity Based Compensation The Equity Plan was adopted by the Company's board of directors and approved by stockholders prior to the consummation of the Company's 2011 initial public offering. Under the Equity Plan, a total of 13,142,813 equity interests are authorized for issuance, and may be issued in the form of Class A common stock, restricted stock units, stock options, units of Manning & Napier Group, or certain classes of membership interests in the Company which may convert into units of Manning & Napier Group. The following table summarizes activity related to awards of restricted stock and restricted stock units (collectively, "stock awards") activity under the Equity Plan for the three months ended March 31, 2019 : Stock Awards Weighted Average Grant Date Fair Value Outstanding at January 1, 2019 1,602,337 $ 5.31 Granted 723,842 $ 2.40 Vested (388,615 ) $ 2.56 Forfeited (15,000 ) $ 12.20 Outstanding at March 31, 2019 1,922,564 $ 4.72 The weighted average fair value of stock awards granted during the three months ended March 31, 2019 was $2.40 , based on the closing sale price of Manning & Napier Inc.'s Class A common stock as reported on the New York Stock Exchange on the date of grant, and, if not entitled to dividends or dividend equivalents during the vesting period, reduced by the present value of such amounts expected to be paid on the underlying shares during the requisite service period. For the three months ended March 31, 2019 and 2018 , the Company recorded approximately $1.4 million and $1.2 million , respectively, of compensation expense related to stock awards under the Equity Plan. As of March 31, 2019 , there was unrecognized compensation expense of approximately $5.3 million related to stock awards, which the Company expects to recognize over a weighted average period of approximately 2.2 years . The aggregate intrinsic value of stock awards that vested during the three months ended March 31, 2019 was approximately $1.0 million . A summary of activity under the Equity Plan related to stock option awards during the three months ended March 31, 2019 is presented below: Stock Option Awards Weighted Average Exercise Price Weighted Average Contractual Term (years) Aggregate Intrinsic Value (in thousands) Outstanding at January 1, 2019 — $ — Granted 3,500,000 $ 2.01 Vested — $ — Forfeited — $ — Outstanding at March 31, 2019 3,500,000 $ 2.01 4.1 $ 315 Exercisable at March 31, 2019 — $ — For the three months ended March 31, 2019 , the Company recorded approximately $0.1 million of compensation expense related to stock options under the Equity Plan. As of March 31, 2019 , there was unrecognized compensation expense of approximately $1.4 million related to stock options, which the Company expects to recognize over a weighted average period of approximately 1.4 years. During the three months ended March 31, 2019 , the Company granted a total of 3,500,000 stock option awards under the Equity Plan, 3,000,000 of which are subject to the achievement of specified performance criteria ("performance options"). The performance options vest in installments, only if the closing price per share of the Company's Class A common stock as reported on the New York Stock Exchange exceeds a certain threshold for 20 consecutive days ("target price") prior to a specified date ("target date"). Target prices range from $3.25 to $7.75 . Target dates by which each target price must be achieved range from three to seven years from the grant date. These performance options are considered to have a market condition, the effect of which is reflected in the grant date fair value of the award. As such, as long as the requisite service is rendered for these awards, compensation expense will be recognized regardless of whether the market condition is achieved. The fair value of these performance options was estimated using a Monte Carlo simulation model and the weighted average grant date fair value for the performance options granted was $0.38 . For stock option awards with service conditions only ("service-based options"), the Company determines the fair value of each option award on the date of grant using the Black-Scholes option pricing model. The weighted average grant date fair value of service-based options granted during the three months ended March 31, 2019 was $0.62 , using the following assumptions: Three months ended March 31, 2019 Expected volatility 45.00% Expected term (in years) 4.9 - 6.9 Risk-free interest rate 2.49% - 2.58% Expected dividend yield 3.98%

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company is comprised of entities that have elected to be treated as either a limited liability company ("LLC") or a “C-Corporation". As such, the entities functioning as LLCs are not liable for or able to benefit from U.S. federal and most state income taxes on their earnings, and earnings (losses) will be included in the personal income tax returns of each entity’s unit holders. The entities functioning as C-Corporations are liable for or able to benefit from U.S. federal and state and local income taxes on their earnings and losses, respectively. The Company’s income tax provision and effective tax rate were as follows: Three months ended March 31, 2019 2018 (in thousands) Earnings from continuing operations before income taxes $ 3,159 $ 7,751 Effective tax rate 7.7 % 6.2 % Provision for income taxes 242 478 Provision for income taxes at statutory rate 663 1,628 Difference between tax at effective vs. statutory rate $ (421 ) $ (1,150 ) For both the three months ended March 31, 2019 and 2018 , the difference between the Company’s recorded provision and the provision that would result from applying the U.S. statutory rate of 21% is primarily attributable to the benefit resulting from the fact that a significant portion of the Company’s operations include a series of flow-through entities which are generally not subject to federal and most state income taxes. Accordingly, a portion of the Company’s earnings are not subject to corporate level taxes.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2019
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and related rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for interim financial reporting and include all adjustments, consisting only of normal recurring adjustments which are, in the opinion of management, necessary for a fair statement of the results for the interim period. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates or assumptions that affect the reported amounts and disclosures in the consolidated financial statements. Actual results could differ from these estimates or assumptions.
Principles of Consolidation	Principles of Consolidation The Company consolidates all majority-owned subsidiaries. In addition, as of March 31, 2019 , Manning & Napier holds an economic interest of approximately 18.6% in Manning & Napier Group but, as managing member, controls all of the business and affairs of Manning & Napier Group. As a result, the Company consolidates the financial results of Manning & Napier Group and records a noncontrolling interest on its consolidated statements of financial condition with respect to the remaining economic interest in Manning & Napier Group held by Manning & Napier Group Holdings, LLC (“M&N Group Holdings”) and Manning & Napier Capital Company, LLC (“MNCC”). All material intercompany transactions have been eliminated in consolidation. In accordance with Accounting Standards Update ("ASU") 2015-02, Consolidation (Topic 810) – Amendments to the Consolidation Analysis , the determination of whether a company is required to consolidate an entity is based on, among other things, an entity’s purpose and design, a company’s ability to direct the activities of the entity that most significantly impact the entity’s economic performance, and whether a company is obligated to absorb losses or receive benefits that could potentially be significant to the entity. The standard also requires ongoing assessments of whether a company is the primary beneficiary of a variable interest entity (“VIE”). When utilizing the voting interest entity ("VOE") model, controlling financial interest is generally defined as majority ownership of voting interests. The Company provides seed capital to its investment teams to develop new strategies and services for its clients. The original seed investment may be held in a separately managed account, comprised solely of the Company's investments or within a mutual fund, where the Company's investments may represent all or only a portion of the total equity investment in the mutual fund. Pursuant to U.S. GAAP, the Company evaluates its investments in mutual funds on a regular basis and consolidates such mutual funds for which it holds a controlling financial interest. When no longer deemed to hold a controlling financial interest, the Company would deconsolidate the fund and classify the remaining investment as either an equity method investment or as trading securities, as applicable. The Company serves as the investment adviser for Manning & Napier Fund, Inc. series of mutual funds (the “Fund”), Exeter Trust Company Collective Investment Trusts (“CIT”) and Rainier Multiple Investment Trust. The Fund, CIT and Rainier Multiple Investment Trust are legal entities, the business and affairs of which are managed by their respective boards of directors. As a result, each of these entities is a VOE. The Company holds, in limited cases, direct investments in a mutual fund (which are made on the same terms as are available to other investors) and consolidates each of these entities where it has a controlling financial interest or a majority voting interest. The Company's investments in the Fund amounted to approximately $3.9 million as of March 31, 2019 and $3.6 million as of December 31, 2018 . As of March 31, 2019 and December 31, 2018 the Company did not have a controlling financial interest in any mutual fund.
Revenue, and Costs to Obtain a Contract	Revenue Investment Management: Investment management fees are computed as a percentage of assets under management ("AUM"). The Company's performance obligation is a series of services that form part of a single performance obligation satisfied over time. Separately managed accounts are paid in advance, typically for a semi-annual or quarterly period, or in arrears, typically for a monthly or quarterly period. When investment management fees are paid in advance, the Company defers the revenue as a contract liability and recognizes it over the applicable period. When investment management fees are paid in arrears, the Company estimates revenue and records a contract asset (accrued accounts receivable) based on AUM as of the most recent month end date. Mutual funds and collective investment trust investment management revenue is calculated and earned daily based on AUM. Revenue is presented net of cash rebates and fees waived pursuant to contractual expense limitations of the funds. The Company also has agreements with third parties who provide recordkeeping and administrative services for employee benefit plans participating in the collective investment trusts. The Company is acting as an agent on behalf of the employee benefit plan sponsors, therefore, investment management revenue is recorded net of fees paid to third party service providers. Distribution and shareholder servicing: The Company receives distribution and servicing fees for providing services to its affiliated mutual funds. Revenue is computed and earned daily based on a percentage of AUM. The performance obligation is a series of services that form part of a single performance obligation satisfied over time. The Company has agreements with third parties who provide distribution and administrative services for its mutual funds. The agreements are evaluated to determine whether revenue should be reported gross or net of payments to third-party service providers. The Company controls the services provided and acts as a principal in the relationship. Therefore, distribution and shareholder servicing revenue is recorded gross of fees paid to third parties. Custodial services: Custodial service fees are calculated as a percentage of the client’s market value with additional fees charged for certain transactions. For the safeguarding and administrative services that are subject to a percentage of market value fee, the Company's performance obligation is a series of services that form part of a single performance obligation satisfied over time. Revenue for transactions assigned a stand-alone selling price is recognized in the period which the transaction is executed. Custodial service fees are billed monthly in arrears. The Company has agreements with third parties who provide safeguarding, recordkeeping and administrative services for their clients. The Company controls the services provided and acts as a principal in the relationship. Therefore, custodial service revenue is recorded gross of fees paid to third parties. Costs to Obtain a Contract Incremental first year commissions directly associated with new separate account and collective investment trust contracts are capitalized and amortized on a straight-line basis over the estimated customer contract period of 7 years for separate accounts and 3 years for collective investment trust contracts. Refer to Note 3 for further discussion.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company generally considers all highly liquid investments with original maturities of three months or less to be cash equivalents. Cash and cash equivalents are primarily held in operating accounts at major financial institutions and also in money market securities. Cash equivalents are stated at cost, which approximates market value due to the short-term maturity of these investments. The fair value of cash equivalents have been classified as Level 1 in accordance with the fair value hierarchy.
Investment Securities	Investment Securities Investment securities are classified as either trading, equity method investments or available-for-sale and are carried at fair value. Fair value is determined based on quoted market prices in active markets for identical or similar instruments. Investment securities classified as trading consist of equity securities, fixed income securities, and investments in mutual funds for which the Company provides advisory services. Realized and unrealized gains and losses on trading securities are recorded in net gains (losses) on investments in the consolidated statements of operations. At March 31, 2019 , trading securities consist of investments held by the Company to provide initial cash seeding for product development purposes and investments to hedge economic exposure to market movements on its deferred compensation plan. Investments classified as equity method investments represent seed investments in which the Company owns between 20-50% of the outstanding voting interests in the affiliated fund or when it is determined that the Company is able to exercise significant influence but not control over the investments. If the seed investment results in significant influence, but not control, the investment will be accounted for as an equity method investment. When using the equity method, the Company recognizes its share of the investee's net income or loss for the period which is recorded in net gains (losses) on investments in the consolidated statements of operations. Investment securities classified as available-for-sale consist of U.S. Treasury notes and other short-term investments. Unrealized gains and losses on available-for-sale securities are excluded from earnings and are reported, net of deferred income tax, as a separate component of accumulated other comprehensive income in stockholders’ equity until realized. The Company periodically reviews each individual security position that has an unrealized loss, or impairment, to determine if that impairment is other-than-temporary. If impairment is determined to be other-than-temporary, the carrying value of the security will be written down to fair value and the loss will be recognized in earnings. Realized gains and losses on sales of available-for-sale securities are computed on a specific identification basis and are recorded in net gains (losses) on investments in the consolidated statements of operations.
Property and Equipment	Property and Equipment Property and equipment is presented net of accumulated depreciation of approximately $11.2 million and $11.3 million as of March 31, 2019 and December 31, 2018 , respectively.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill represents the excess cost over the fair value of the identifiable net assets of acquired companies. Identifiable intangible assets generally represent the cost of client relationships and investment management agreements acquired as well as trademarks. Goodwill and indefinite-lived assets are tested for impairment annually or more frequently if events or circumstances indicate that the carrying value may not be recoverable. Intangible assets subject to amortization are tested for impairment whenever events or circumstances indicate that the carrying value may not be recoverable. Goodwill and intangible assets require significant management estimate and judgment, including the valuation and expected life determination in connection with the initial purchase price allocation and the ongoing evaluation for impairment.
Leases	Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use ("ROU") assets, accrued expenses and other liabilities and operating lease liabilities, non-current on its consolidated statements of financial condition. Finance leases are included in other long-term assets, accrued expenses and other liabilities, and other long-term liabilities on its consolidated statements of financial condition. ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The incremental borrowing rate, for each identified lease, is the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term. The operating lease ROU asset is reduced for any lease incentives. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that it will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are combined for all classes of underlying assets.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which is intended to increase transparency and comparability among organizations by recognizing all lease transactions (with terms in excess of 12 months) on the balance sheet as a lease liability and a right-of-use asset (as defined). In July 2018, the FASB issued ASU 2018-11, Leases - Targeted Improvements , which provides an optional transition method related to implementing the new lease standard. The Company adopted the new standard on its effective date of January 1, 2019. Refer to Note 8 for further discussion regarding the impact of adoption. In February 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income . The ASU requires a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the newly enacted federal corporate income tax rate as a result of the Tax Cuts and Jobs Act. The amount of the reclassification is the difference between the historical corporate income tax rate and the newly enacted 21% corporate income tax rate. The ASU will be effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company's adoption of ASU 2018-02 on January 1, 2019 did not have a material impact on its consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment , which simplifies the accounting for goodwill impairments by eliminating step two from the goodwill impairment test. The ASU requires goodwill impairments to be measured on the basis of the fair value of the reporting unit relative to the reporting unit's carrying amount rather than on the basis of the implied amount of goodwill relative to the goodwill balance of the reporting unit. The ASU is effective for annual and interim impairment tests for periods beginning after December 15, 2019. Early adoption is allowed for annual and interim impairment tests occurring after January 1, 2017. The Company is evaluating the effect of adopting this new accounting standard.

These employees are required to render service until their agreed upon termination date (which varies from person to person) in order to receive the benefits and as such, the liability will be recognized ratably over the applicable service period. The Company estimates the total employee severance costs under the offering to be approximately $2.6 million , of which approximately $2.2 million was recognized during the year ended December 31, 2018 . During the three months ended March 31, 2019 , the Company recognized approximately $0.1 million of severance costs under the offering and approximately $0.4 million as a result of involuntary workforce reductions.
