Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting PoliciesThe unaudited condensed consolidated financial statements of FTI Consulting, Inc., including its consolidated subsidiaries (collectively, the “Company,” “we,” “our” or “FTI Consulting”), presented herein, have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and under the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Some of the information and footnote disclosures normally included in annual financial statements have been condensed or omitted pursuant to those rules and regulations. Certain prior period amounts have been reclassified to conform to the current period presentation. In management’s opinion, the interim financial statements reflect all adjustments that are necessary for a fair presentation of the results for the interim periods presented. All adjustments made were normal recurring accruals. Results of operations for the interim periods presented herein are not necessarily indicative of results of operations for a full year. These financial statements should be read in conjunction with the consolidated financial statements and the notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC.

Accounting Changes and Error Corrections [Abstract]
New Accounting Standards	New Accounting Standards In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity , which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. The ASU also removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and simplifies the diluted earnings per share calculation in certain areas. The amendments in this ASU are effective for annual and interim periods beginning after December 15, 2021, although early adoption is permitted. The Company is in the process of evaluating the impact of this new guidance on its consolidated financial statements.

Earnings per Common Share

Earnings Per Share [Abstract]
Earnings per Common Share	Earnings per Common Share Basic earnings per common share is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per common share adjusts basic earnings per common share for the effects of potentially dilutive common shares. Potentially dilutive common shares include the dilutive effects of shares issuable under our equity compensation plans, including stock options and restricted shares (restricted share awards, restricted stock units and performance stock units), each using the treasury stock method. Because we expect to settle the principal amount of the outstanding 2.0% convertible senior notes due 2023 ("2023 Convertible Notes") in cash, we use the treasury stock method for calculating the potential dilutive effect of the conversion feature on earnings per common share, if applicable. The conversion feature had a dilutive impact on earnings per common share for the three months ended March 31, 2021 and 2020, as the average market price per share of our common stock for the periods exceeded the conversion price of $101.38 per share. See Note 8, "Debt" for additional information about the 2023 Convertible Notes.

Revenues

Revenue from Contract with Customer [Abstract]
Revenues	Revenues We generate the majority of our revenues by providing consulting services to our clients. Most of our consulting service contracts are based on one of the following types of contract arrangements: • Time and expense arrangements require the client to pay us based on the number of hours worked at contractually agreed-upon rates. We recognize revenues for these contract arrangements based on hours incurred and contracted rates utilizing a right-to-invoice practical expedient because we have a right to consideration for services completed to date. When a time and expense arrangement has a not-to-exceed or "cap" amount and we expect to perform work in excess of the cap, we recognize revenues up to the cap amount specified by the client, based on the efforts or hours incurred as a percentage of total efforts or hours expected to be incurred (i.e., proportional performance method). • Fixed-fee arrangements require the client to pay a fixed fee in exchange for a predetermined set of professional services. We recognize revenues earned to date by applying the proportional performance method. Generally, these arrangements have one performance obligation. • Performance-based or contingent arrangements represent forms of variable consideration. In these arrangements, our fees are based on the attainment of contractually defined objectives with our client, such as completing a business transaction or assisting the client in achieving a specific business objective. We recognize revenues earned to date in an amount that is probable not to reverse and by applying the proportional performance method when the criteria for over time revenue recognition are met. Certain fees in our time and materials arrangements may be subject to approval by a third-party, such as a bankruptcy court and other regulatory agency. In such cases, we record revenues based on the amount we estimate we will be entitled to in exchange for our services and only to the extent a significant reversal of revenue is not likely to occur when the uncertainty associated with the estimate is subsequently resolved. Potential fee reductions imposed by bankruptcy courts and other regulatory agencies or negotiated with specific clients are estimated on a specific identification basis. Our estimates may vary depending on the nature of the engagement, client economics, historical experience and other appropriate factors. When there are changes in our estimates of potential fee reductions, we record such changes to revenues with a corresponding offset to our billed and unbilled accounts receivable. Revenues recognized during the current period may include revenues from performance obligations satisfied or partially satisfied in previous periods. This primarily occurs when the estimated transaction price has changed based on our current probability assessment over whether the agreed-upon outcome for our performance-based and contingent arrangements will be achieved. The aggregate amount of revenues recognized related to a change in the transaction price in the current period, which related to performance obligations satisfied or partially satisfied in a prior period, was $3.9 million and $8.3 million for the three months ended March 31, 2021 and 2020, respectively. Unfulfilled performance obligations primarily consist of fees not yet recognized on certain fixed-fee arrangements and performance-based and contingent arrangements. As of March 31, 2021 and December 31, 2020, the aggregate amount of the remaining contract transaction price allocated to unfulfilled performance obligations was $7.9 million and $8.5 million, respectively. We expect to recognize the majority of the related revenues over the next 24 months. We elected to utilize the optional exemption to exclude from this disclosure fixed-fee and performance-based and contingent arrangements with an original expected duration of one year or less and to exclude our time and expense arrangements for which revenues are recognized using the right-to-invoice practical expedient. Contract assets are defined as assets for which we have recorded revenue but are not yet entitled to receive our fees because certain events, such as completion of the measurement period or client approval, must occur. The contract asset balance was $1.8 million as of March 31, 2021 and $2.6 million as of December 31, 2020.

We record our estimate of lifetime expected credit losses concurrently with the initial recognition of the underlying receivable. Accounts receivable, net of the allowance for expected credit losses, represents the amount we expect to collect. At each reporting date, we adjust the allowance for expected credit losses to reflect our current estimate. The following table summarizes the total provision for expected credit losses and write-offs: Three Months Ended March 31, 2021 2020 Provision for expected credit losses (1) $ 4,832 $ 3,872 Write-offs $ 6,916 $ 6,066 (1) Adjustments to the allowance for expected credit losses are recorded to selling, general & administrative ("SG&A") expenses on the Condensed Consolidated Statements of Comprehensive Income.

(2) The carrying values include unamortized deferred debt issue costs and debt discount. The fair values of financial instruments not included in the tables above are estimated to be equal to their carrying values as of March 31, 2021 and December 31, 2020. We estimate the fair value of our 2023 Convertible Notes based on their last actively traded prices. The fair value of our 2023 Convertible Notes is classified within Level 2 of the fair value hierarchy because it is traded in less active markets. We estimate the fair value of acquisition-related contingent consideration using either a probability-weighted discounted cash flow model or a Monte Carlo simulation. These fair value estimates represent Level 3 measurements as they are based on significant inputs not observed in the market and reflect our own assumptions. Significant increases (or decreases) in these unobservable inputs in isolation would result in significantly lower (or higher) fair values. We reassess the fair value of our acquisition-related contingent consideration at each reporting period based on additional information as it becomes available. The table below presents the change in our liability for acquisition-related contingent consideration for our Level 3 financial instruments: Contingent Consideration Balance at December 31, 2020 $ 20,118 Accretion expense (1) 1,289 Payments (1,000) Foreign currency translation adjustment (2) (612) Balance at March 31, 2021 $ 19,795 Contingent Consideration Balance at December 31, 2019 $ 14,826 Accretion expense (1) 506 Foreign currency translation adjustment (2) (148) Balance at March 31, 2020 $ 15,184 (1) Accretion expense is included in SG&A expenses on the Condensed Consolidated Statements of Comprehensive Income.

The 2023 Convertible Notes bear interest at a fixed rate of 2.0% per year, payable semiannually in arrears on February 15th and August 15th of each year and will mature on August 15, 2023, unless earlier converted or repurchased. The 2023 Convertible Notes are senior unsecured obligations of the Company. The 2023 Convertible Notes are convertible at maturity at a conversion rate of 9.8643 shares of our common stock per $1,000 principal amount of the 2023 Convertible Notes (equivalent to a conversion price of approximately $101.38 per share of common stock). Subject to the conditions set forth in the indenture governing the 2023 Convertible Notes, holders may convert their 2023 Convertible Notes at any time prior to the close of business on the business day immediately preceding May 15, 2023. The circumstances required to allow the holders to convert their 2023 Convertible Notes prior to maturity were not met as of March 31, 2021. The excess of the principal amount of the liability over its carrying amount ("debt discount") is amortized to interest expense over the term of the 2023 Convertible Notes using the effective interest rate method. We incurred debt issue costs and allocated the total amount to the liability and equity components of the 2023 Convertible Notes based on their relative values. The debt issue costs attributable to the liability component are amortized to interest expense over the term of the 2023 Convertible Notes using the effective interest rate method. Issuance costs attributable to the equity component were netted with the equity component in stockholders' equity. The table below summarizes the amount of interest cost recognized by us for both the contractual interest expense and amortization of the debt discount for the 2023 Convertible Notes: Three Months Ended March 31, 2021 2020 Contractual interest expense $ 1,581 $ 1,581 Amortization of debt discount (1) 2,348 2,225 Total $ 3,929 $ 3,806 (1) The effective interest rate of the liability component is 5.45%. Credit Facility On June 26, 2015, we entered into a credit agreement, which provides for a $550.0 million senior secured bank revolving credit facility (“Original Credit Facility”) maturing on June 26, 2020. In November 2018, we amended and restated the credit agreement to the Original Credit Facility, to, among other things, extend the maturity to November 30, 2023 and incurred an additional $1.7 million of debt issuance costs (the Original Credit Facility as amended and restated, the “Credit Facility”). The Company classified the borrowings under the Company’s Credit Facility as long-term debt in the accompanying Condensed Consolidated Balance Sheets, as amounts due under the Credit Facility are not contractually required or expected to be liquidated for more than one year from the applicable balance sheet date. As of March 31, 2021, $1.1 million of the borrowing limit under the Credit Facility was utilized (and, therefore, unavailable) for letters of credit. There were $1.2 million and $1.3 million of unamortized debt issue costs related to the Credit Facility as of March 31, 2021 and December 31, 2020, respectively. These amounts are included in “Other assets” on our Condensed Consolidated Balance Sheets.

Leases [Abstract]
Leases	Leases We lease office space and equipment under non-cancelable operating leases. We recognize operating lease expense on a straight-line basis over the lease term, which may include renewal or termination options that are reasonably certain of exercise. Leases with an initial term of 12 months or less are not recorded on the balance sheet and are expensed on a straight-line basis. Most leases include one or more options to renew, with renewal terms that can extend the lease term from six months to seven years. The exercise of lease renewal options is at our sole discretion. Certain of our lease agreements include rental payments that are adjusted periodically for inflation. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. The table below summarizes the carrying amount of our operating lease assets and liabilities: Leases Classification March 31, 2021 December 31, 2020 Assets Operating lease assets Operating lease assets $ 148,322 $ 156,645 Total lease assets $ 148,322 $ 156,645 Liabilities Current Operating lease liabilities Accounts payable, accrued expenses and other $ 38,494 $ 42,716 Noncurrent Operating lease liabilities Noncurrent operating lease liabilities 153,376 161,677 Total lease liabilities $ 191,870 $ 204,393 The table below summarizes total lease costs: Three Months Ended March 31, Lease Cost 2021 2020 Operating lease costs $ 12,082 $ 11,900 Short-term lease costs 489 522 Variable lease costs 3,463 2,987 Sublease income (1,048) (1,090) Total lease cost, net $ 14,986 $ 14,319 We sublease certain of our leased office spaces to third parties. Our sublease portfolio consists of leases of office space that we have vacated before the lease term expiration. Operating lease expense on vacated office space is reduced by sublease rental income, which is recorded to SG&A expenses on the Condensed Consolidated Statements of Comprehensive Income. Our sublease arrangements do not contain renewal options or restrictive covenants. We estimate future sublease rental income to be $3.4 million in the remainder of 2021, $0.8 million in 2022, $0.6 million in 2023, $0.6 million in 2024 and $0.3 million in 2025. There is no future sublease rental income estimated for the years beyond 2025.

Equity [Abstract]
Stockholders' Equity	Stockholders’ Equity On June 2, 2016, our Board of Directors authorized a stock repurchase program of up to $100.0 million (the “Repurchase Program”). On each of May 18, 2017, December 1, 2017, February 21, 2019 and February 20, 2020, our Board of Directors authorized an additional $100.0 million, respectively. On each of July 28, 2020 and December 3, 2020, our Board of Directors authorized an additional $200.0 million, respectively, increasing the Repurchase Program to an aggregate authorization of $900.0 million. No time limit has been established for the completion of the Repurchase Program, and the Repurchase Program may be suspended, discontinued or replaced by the Board of Directors at any time without prior notice. As of March 31, 2021, we have $167.1 million available under the Repurchase Program to repurchase additional shares. The following table details our stock repurchases under the Repurchase Program: Three Months Ended March 31, 2021 2020 Shares of common stock repurchased and retired 422 450 Average price paid per share $ 109.37 $ 111.73 Total cost $ 46,124 $ 50,301 As we repurchase our common shares, we reduce stated capital on our Condensed Consolidated Balance Sheets for the $0.01 of par value of the shares repurchased, with the excess purchase price over par value recorded as a reduction to additional paid-in capital. If additional paid-in capital is reduced to zero, we record the remainder of the excess purchase price over par value as a reduction of retained earnings. During the three months ended March 31, 2021, due to the volume of repurchases, we recorded a reduction to stated capital for the par value of the shares repurchased, with a portion of the excess purchase price over par value recorded as a reduction to additional paid-in capital of $3.0 million, which reduced additional paid-in capital to zero, and the remainder of the excess purchase price over par value of $43.1 million recorded as a reduction of retained earnings. Common stock outstanding was 34.2 million shares and 34.5 million shares as of March 31, 2021 and December 31, 2020, respectively. Common stock outstanding includes unvested restricted stock awards, which are considered issued and outstanding under the terms of the restricted stock award agreements.

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting We manage our business in five reportable segments: Corporate Finance, FLC, Economic Consulting, Technology and Strategic Communications. Our Corporate Finance segment focuses on the strategic, operational, financial, transactional and capital needs of our clients around the world. Our clients include companies, boards of directors, investors, private equity sponsors, banks, lenders, and other financing sources and creditor groups, as well as other parties-in-interest. We deliver a wide range of services centered around three core offerings: business transformation, transactions and turnaround, restructuring and bankruptcy. Our FLC segment provides law firms, companies, government entities and other interested parties with a multidisciplinary and independent range of services in risk and investigations and disputes, including a focus on highly regulated industries such as our construction & environmental solutions and health solutions services. These services are supported by our data & analytics services which help our clients analyze large, disparate sets of data related to their business operations and support our clients during regulatory inquiries and commercial disputes. We deliver a wide range of services centered around five core offerings: construction & environmental solutions, data & analytics, disputes, health solutions and risk and investigations. Our Economic Consulting segment, including subsidiary Compass Lexecon LLC, provides law firms, companies, government entities and other interested parties with analyses of complex economic issues for use in international arbitration, legal and regulatory proceedings, and strategic decision making and public policy debates around the world. We deliver a wide range of services centered around three core offerings: antitrust & competition economics, financial economics and international arbitration. Our Technology segment provides companies, law firms and government entities with a comprehensive global portfolio of e-discovery, information governance, privacy and security and corporate legal operations solutions. We deliver a full spectrum of services including data collection, data processing, document review, hosting, advanced analytics and consulting to help clients secure, govern, analyze and understand their data in the context of compliance and risk. Our Strategic Communications segment develops and executes communications strategies to help management teams, boards of directors, law firms, governments and regulators manage change and mitigate risk surrounding transformational and disruptive events, including transactions, investigations, disputes, crises, regulation and legislation. We deliver a wide range of services centered around three core offerings: corporate reputation, financial communications and public affairs. We evaluate the performance of our operating segments based on Adjusted Segment EBITDA, a GAAP financial measure. We define Adjusted Segment EBITDA as a segment’s share of consolidated operating income before depreciation, amortization of intangible assets, remeasurement of acquisition-related contingent consideration, special charges and goodwill impairment charges. We define Total Adjusted Segment EBITDA, which is a non-GAAP financial measure, as the total of Adjusted Segment EBITDA for all segments, which excludes unallocated corporate expenses. We use Adjusted Segment EBITDA as a basis to internally evaluate the financial performance of our segments because we believe it reflects current core operating performance and provides an indicator of the segment’s ability to generate cash. The table below presents revenues and Adjusted Segment EBITDA for our reportable segments: Three Months Ended March 31, 2021 2020 Revenues Corporate Finance $ 226,203 $ 207,749 FLC 150,821 147,597 Economic Consulting 169,273 132,138 Technology 79,459 58,723 Strategic Communications 60,521 58,386 Total revenues $ 686,277 $ 604,593 Adjusted Segment EBITDA Corporate Finance $ 37,439 $ 48,946 FLC 29,432 21,208 Economic Consulting 26,579 12,710 Technology 21,598 14,484 Strategic Communications 10,398 8,776 Total Adjusted Segment EBITDA $ 125,446 $ 106,124 The table below reconciles net income to Total Adjusted Segment EBITDA: Three Months Ended March 31, 2021 2020 Net income $ 64,496 $ 56,747 Add back: Income tax provision 20,247 16,465 Interest income and other (1,034) (5,017) Interest expense 4,797 4,861 Unallocated corporate expenses 26,710 23,591 Segment depreciation expense 7,430 7,146 Amortization of intangible assets 2,800 2,331 Total Adjusted Segment EBITDA $ 125,446 $ 106,124

Accounting Changes and Error Corrections [Abstract]
Basis of Presentation	The unaudited condensed consolidated financial statements of FTI Consulting, Inc., including its consolidated subsidiaries (collectively, the “Company,” “we,” “our” or “FTI Consulting”), presented herein, have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and under the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Some of the information and footnote disclosures normally included in annual financial statements have been condensed or omitted pursuant to those rules and regulations. Certain prior period amounts have been reclassified to conform to the current period presentation. In management’s opinion, the interim financial statements reflect all adjustments that are necessary for a fair presentation of the results for the interim periods presented. All adjustments made were normal recurring accruals. Results of operations for the interim periods presented herein are not necessarily indicative of results of operations for a full year. These financial statements should be read in conjunction with the consolidated financial statements and the notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC.
Recently Adopted Accounting Standards and Accounting Standards Not Yet Adopted	In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity , which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. The ASU also removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and simplifies the diluted earnings per share calculation in certain areas. The amendments in this ASU are effective for annual and interim periods beginning after December 15, 2021, although early adoption is permitted. The Company is in the process of evaluating the impact of this new guidance on its consolidated financial statements.
