| Accounting Policies [Abstract] | |
| Basis of Presentation and Significant Accounting Policies | Basis of Presentation and Significant Accounting Policies 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, 2018 filed with the SEC. Leases As of January 1, 2019, the Company adopted Accounting Standards Update ("ASU") 2016-02, Leases, which was amended in some respects by subsequent ASUs (collectively Accounting Standards Codification (“ASC") 842 ("ASC 842")) and supersedes existing lease guidance. The standard requires us to record right-of-use ("ROU") assets and corresponding lease liabilities on the balance sheet and disclose key quantitative and qualitative information about our lease contracts. Under ASC 842, we determine if a contract is a leasing arrangement at inception. ROU assets represent our right to control the use of an identified asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. We use the incremental borrowing rate on the commencement date in determining the present value of our lease payments. We recognize operating lease expense for our operating leases on a straight-line basis over the lease term, which may include renewal or termination options that are reasonably certain of exercise. Lease and non-lease components are accounted for together as a single lease component for operating leases associated with our office space and our equipment leases. We apply a portfolio approach for certain equipment leases to effectively account for the operating lease ROU assets and liabilities.

| Accounting Changes and Error Corrections [Abstract] | |
| New Accounting Standards | New Accounting Standards Recently Adopted Accounting Standards In February 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-02, Leases, which was amended in some respects by subsequent ASUs. We adopted ASC 842 using the modified retrospective basis for reporting. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard, which allowed us to carry forward the historical lease classification for existing leases on the adoption date, and allowed us not to reassess whether an existing contract contains a lease or initial direct costs. As permitted by the guidance, prior comparative periods will not be adjusted under this method. See Note 1, "Basis of Presentation and Significant Accounting Policies" for a description of the significant accounting policies for our operating leases. See Note 9, "Leases" for the disclosures required under ASC 842. The adoption of this standard resulted in recognition of ROU assets in the amount of $148.5 million and lease liabilities in the amount of $206.7 million for operating leases on our Condensed Consolidated Balance Sheets as of January 1, 2019. Our existing deferred rent and cease-use liabilities were $62.3 million as of December 31, 2018 and were included as a reduction to the initial measurement of our operating lease assets. Our existing prepaid rent balance was $4.1 million as of December 31, 2018 and was included as a reduction to the initial measurement of our operating lease liabilities. There was no material impact on the Condensed Consolidated Statements of Comprehensive Income, Condensed Consolidated Statements of Stockholders’ Equity or Condensed Consolidated Statements of Cash Flows. Accounting Standards Not Yet Adopted In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements for fair value measurements. The guidance promotes a framework to help improve the effectiveness of disclosures in the notes to the financial statements and is effective for annual and interim periods beginning after December 15, 2019, although early adoption is permitted. The Company is in the process of evaluating the impact of this new guidance on its consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, Internal Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract, which requires the Company to capitalize implementation costs of a hosting arrangement that is a service contract and expense those costs over the term of the hosting arrangement. The guidance is effective for annual and interim periods beginning after December 15, 2019 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 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, 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 and nine months ended September 30, 2019, as the average market price per share of our common stock for the period exceeded the conversion price of $101.38 per share. See Note 8, "Debt" for additional information about the 2023 Convertible Notes.

| 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 arrangements:
individual performance obligations within each arrangement; however, these arrangements generally have one performance obligation.
Revenues are recognized when we satisfy a performance obligation by transferring services promised in a contract to a customer and in an amount that reflects the consideration that we expect to receive in exchange for those services. Performance obligations in our contracts represent distinct or separate services that we provide to our customers. 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 $7.0 million and $23.5 million for the three and nine months ended September 30, 2019, respectively, and $8.7 million and $12.9 million for the three and nine months ended September 30, 2018, respectively. Unfulfilled performance obligations represent the remaining contract transaction prices allocated to the performance obligations that are unsatisfied. Unfulfilled performance obligations primarily consist of fees not yet recognized on a proportional performance basis for fixed-fee arrangements and performance-based and contingent arrangements. As of September 30, 2019 and December 31, 2018, the aggregate amount of the remaining contract transaction price allocated to unfulfilled performance obligations was $3.0 million and $8.8 million, respectively. We expect to recognize the majority of the related revenues over the next 24 months. 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 $3.4 million as of September 30, 2019 and $2.4 million as of December 31, 2018. Contract liabilities are defined as liabilities incurred when we have received consideration but have not yet performed the agreed upon services. This may occur when clients pay us upfront fees before we begin work for them. The contract liability balance was immaterial as of September 30, 2019 and December 31, 2018.

| Allowance For Doubtful Accounts And Unbilled Services [Abstract] | |
| Accounts Receivable and Allowance for Doubtful Accounts | Accounts Receivable and Allowance for Doubtful Accounts Timing of revenue recognition often differs from the timing of billing to our customers. Generally, we transfer goods or services to a customer before the customer pays consideration or payment is due. If we have an unconditional right to invoice and receive payment for goods or services already provided, we record billed and unbilled receivables on our Condensed Consolidated Balance Sheets. Our contract terms generally include a requirement of payment within 30 days when no contingencies exist. Payment terms and conditions vary depending on the jurisdiction, market and type of service, and whether regulatory or other third-party approvals are required. In addition, contracts may be negotiated per the client’s request; or at times we are asked to execute contracts in a form provided by customers that might include different terms. We record adjustments to the allowance for doubtful accounts and unbilled services as a reduction in revenues when there are changes in estimates of fee reductions, such as those fee reductions imposed by bankruptcy courts and other regulatory institutions for both billed and unbilled receivables. The allowance for doubtful accounts and unbilled services is also adjusted after the related work has been billed to the client and we discover that collectability is not reasonably assured. These adjustments are recorded to “Selling, general and administrative expenses” ("SG&A") on the Condensed Consolidated Statements of Comprehensive Income. Our bad debt expense totaled $7.3 million and $13.6 million for the three and nine months ended September 30, 2019, respectively, and $3.2 million and $12.0 million for the three and nine months ended September 30, 2018, respectively.

During the three months ended September 30, 2019, we acquired Andersch AG ("Andersch"), a leading German restructuring advisory firm, within our Corporate Finance & Restructuring segment. We recorded $30.8 million in goodwill based on a preliminary purchase price allocation as a result of the acquisition. We have included the results of the acquired business’s operations in the Corporate Finance & Restructuring segment since its acquisition date. Other Intangible Assets Other intangible assets were as follows:
Other intangible assets with finite lives are amortized over their estimated useful lives.

(1) Actual amortization expense to be reported in future periods could differ from these estimates because of new intangible asset acquisitions, changes in useful lives or other relevant factors or changes.

| Financial Instruments | Financial Instruments The following table presents the carrying amounts and estimated fair values of our financial instruments by hierarchy level as of September 30, 2019 and December 31, 2018:
The fair values of financial instruments not included in the table above are estimated to be equal to their carrying values as of September 30, 2019 and December 31, 2018. We estimate the fair value of our 2023 Convertible Notes based on their last actively traded prices. The fair value of our debt 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. The significant unobservable inputs used in the fair value measurements of our acquisition-related contingent consideration include measures of discount rates, future cash flows, volatility and the cost of debt. Significant increases (decreases) in these unobservable inputs in isolation would result in a significantly lower (higher) fair value. The fair value of our contingent consideration is reassessed at each reporting period by the Company based on additional information as it becomes available. Any change in the fair value of an acquisition’s contingent consideration liability results in a remeasurement gain or loss that is recorded in “Selling, general and administrative expenses” on the Consolidated Statements of Comprehensive Income. During the three and nine months ended September 30, 2019 and 2018, there was no change in the estimated fair value of future expected contingent consideration payments.

| Debt | Debt The table below summarizes the components of the Company’s debt:
2023 Convertible Notes On August 20, 2018, we issued the 2023 Convertible Notes in an aggregate principal amount of $316.3 million. 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 an initial conversion rate of 9.8643 shares of our common stock per $1,000 principal amount of the 2023 Convertible Notes (equivalent to an initial conversion price of approximately $101.38 per share of common stock). The circumstances required to allow the holders to convert their 2023 Convertible Notes were not met as of September 30, 2019. 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:
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 of the Original Credit Facility 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”). There were no borrowings outstanding under the Credit Facility as of September 30, 2019 and December 31, 2018. Additionally, $1.0 million of the borrowing limit under the Credit Facility was utilized for letters of credit as of September 30, 2019. There were $2.4 million and $3.6 million of unamortized debt issue costs related to the Credit Facility as of September 30, 2019 and December 31, 2018, respectively. These amounts were included in “Other assets” on our Condensed Consolidated Balance Sheets.

| 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. Leases with an initial term of 12 months or less are not recorded on the balance sheet. Most leases include one or more options to renew, with renewal terms that can extend the lease term from six months to nine 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:
The table below summarizes total lease costs for the three and nine months ended September 30, 2019, respectively:
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 $1.2 million for the remainder of 2019, $4.9 million in 2020, $4.5 million in 2021, $0.7 million in 2022, $0.6 million in 2023 and $0.9 million in years beyond 2023. The maturity analysis below summarizes the remaining future undiscounted cash flows for our operating leases, a reconciliation to operating lease liabilities reported on the Condensed Consolidated Balance Sheet, our weighted-average remaining lease term and weighted average discount rate:

| Segment Reporting | Segment Reporting We manage our business in five reportable segments: Corporate Finance & Restructuring ("Corporate Finance"), Forensic and Litigation Consulting ("FLC"), Economic Consulting, Technology and Strategic Communications. Our Corporate Finance segment focuses on the strategic, operational, financial and capital needs of our clients around the world and delivers a wide range of service offerings related to restructuring, business transformation and transaction support. Our restructuring practice includes corporate restructuring, including bankruptcy and interim management services. Our business transformation and transactions practices include financial, operational and performance improvement services, as well as due diligence, financing advisory, mergers and acquisitions (“M&A”) advisory, M&A integration, carveout support and valuations. Our FLC segment provides law firms, companies, government clients and other interested parties with multidisciplinary, independent dispute advisory, investigations, data analytics, forensic accounting, business intelligence and risk mitigation services, as well as interim management and performance improvement services for our health solutions practice clients. Our Economic Consulting segment provides law firms, companies, government entities and other interested parties with analysis of complex economic issues for use in legal, regulatory and international arbitration proceedings, strategic decision making and public policy debates in the U.S. and around the world. Our Technology segment provides corporations and law firms with a comprehensive and global portfolio of consulting and services for information governance, privacy and security, electronic discovery ("e-discovery") and insight analytics. Our consulting expertise enables clients to more confidently govern, secure, find, analyze and rapidly understand their data in the context of compliance and risk. Our Strategic Communications segment designs and executes communications strategies for management teams and boards of directors to help them seize opportunities, manage financial, regulatory and reputational challenges, navigate market disruptions, articulate their brand, stake a competitive position, and preserve and grow their operations. 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, 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 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:

| Basis of Presentation | 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, 2018 filed with the SEC.

| Leases | Leases As of January 1, 2019, the Company adopted Accounting Standards Update ("ASU") 2016-02, Leases, which was amended in some respects by subsequent ASUs (collectively Accounting Standards Codification (“ASC") 842 ("ASC 842")) and supersedes existing lease guidance. The standard requires us to record right-of-use ("ROU") assets and corresponding lease liabilities on the balance sheet and disclose key quantitative and qualitative information about our lease contracts. Under ASC 842, we determine if a contract is a leasing arrangement at inception. ROU assets represent our right to control the use of an identified asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. We use the incremental borrowing rate on the commencement date in determining the present value of our lease payments. We recognize operating lease expense for our operating leases on a straight-line basis over the lease term, which may include renewal or termination options that are reasonably certain of exercise. Lease and non-lease components are accounted for together as a single lease component for operating leases associated with our office space and our equipment leases. We apply a portfolio approach for certain equipment leases to effectively account for the operating lease ROU assets and liabilities.
|
| New Accounting Standards | Recently Adopted Accounting Standards In February 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-02, Leases, which was amended in some respects by subsequent ASUs. We adopted ASC 842 using the modified retrospective basis for reporting. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard, which allowed us to carry forward the historical lease classification for existing leases on the adoption date, and allowed us not to reassess whether an existing contract contains a lease or initial direct costs. As permitted by the guidance, prior comparative periods will not be adjusted under this method. See Note 1, "Basis of Presentation and Significant Accounting Policies" for a description of the significant accounting policies for our operating leases. See Note 9, "Leases" for the disclosures required under ASC 842. The adoption of this standard resulted in recognition of ROU assets in the amount of $148.5 million and lease liabilities in the amount of $206.7 million for operating leases on our Condensed Consolidated Balance Sheets as of January 1, 2019. Our existing deferred rent and cease-use liabilities were $62.3 million as of December 31, 2018 and were included as a reduction to the initial measurement of our operating lease assets. Our existing prepaid rent balance was $4.1 million as of December 31, 2018 and was included as a reduction to the initial measurement of our operating lease liabilities. There was no material impact on the Condensed Consolidated Statements of Comprehensive Income, Condensed Consolidated Statements of Stockholders’ Equity or Condensed Consolidated Statements of Cash Flows. Accounting Standards Not Yet Adopted In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements for fair value measurements. The guidance promotes a framework to help improve the effectiveness of disclosures in the notes to the financial statements and is effective for annual and interim periods beginning after December 15, 2019, although early adoption is permitted. The Company is in the process of evaluating the impact of this new guidance on its consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, Internal Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract, which requires the Company to capitalize implementation costs of a hosting arrangement that is a service contract and expense those costs over the term of the hosting arrangement. The guidance is effective for annual and interim periods beginning after December 15, 2019 although early adoption is permitted. The Company is in the process of evaluating the impact of this new guidance on its consolidated financial statements.
