Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Unless otherwise noted below, there have been no material changes to the accounting policies presented in Note 1 - “Summary of Significant Accounting Policies” of the Notes to Consolidated Financial Statements, included in Item 8. Financial Statements and Supplementary Data of the 2017 Annual Report on Form 10-K. Basis of Presentation The unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC regarding interim financial reporting. Accordingly, certain information and footnotes normally required by U.S. GAAP for complete financial statements have been condensed or omitted pursuant to those rules and regulations, although Kforce believes that the disclosures made are adequate to make the information not misleading. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our 2017 Annual Report on Form 10-K. In management’s opinion, the accompanying unaudited condensed consolidated financial statements reflect all adjustments considered necessary for a fair presentation. The Unaudited Condensed Consolidated Balance Sheet as of December 31, 2017 was derived from our audited Consolidated Balance Sheet as of December 31, 2017 , as presented in our 2017 Annual Report on Form 10-K. Our quarterly operating results are affected by the number of billing days in a particular quarter, the seasonality of our clients’ businesses and increased holiday and vacation days taken. In addition, we typically experience an increase in costs in the first quarter of each fiscal year as a result of certain U.S. state and federal employment tax resets, which negatively impacts our gross profit and overall profitability. The results of operations for any interim period may be impacted by these factors and are not necessarily indicative of, nor comparable to, the results of operations for a full year. Principles of Consolidation The unaudited condensed consolidated financial statements include the accounts of Kforce Inc. and its subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. References in this document to “Kforce,” “the Company,” “we,” “the Firm,” “management,” “our” or “us” refer to Kforce Inc. and its subsidiaries, except where the context indicates otherwise. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The most important of these estimates and assumptions relate to the following: revenue transaction prices; allowance for doubtful accounts; income taxes; self-insured liabilities for workers’ compensation and health insurance; obligations for pension plans and goodwill and any related impairment. Although these and other estimates and assumptions are based on the best available information, actual results could be materially different from these estimates. Earnings per Share Basic earnings per share is computed as net income divided by the weighted average number of common shares outstanding (“WASO”) during the period. WASO excludes unvested shares of restricted stock. Diluted earnings per share is computed by dividing net income by diluted WASO. Diluted WASO includes the dilutive effect of potentially dilutive securities such as unvested shares of restricted stock using the treasury stock method, except where the effect of including potential common shares would be anti-dilutive. For the three months ended March 31, 2018 and 2017 , there were 290 thousand and 286 thousand common stock equivalents included in the diluted WASO, respectively. For the three months ended March 31, 2018 and 2017 , there were insignificant anti-dilutive common stock equivalents. New Accounting Standards Recently Adopted Accounting Standards In May 2014, the FASB issued authoritative guidance regarding revenue from contracts with customers, which specifies that revenue should be recognized when control of the promised goods or services is transferred to our customers at an amount that reflects the consideration to which we expect to be entitled to in exchange for those goods or services. The amended guidance (“Topic 606”) is effective for annual and interim reporting periods beginning after December 15, 2017. We adopted this new standard effective January 1, 2018, using the modified retrospective transition method with a cumulative adjustment to the opening balance of retained earnings. The comparative information continues to be reported under the accounting standards in effect for the period presented ("Topic 605"). Refer to Note C - "Revenue Recognition" for additional accounting policy and transition disclosures. Accounting Standards Not Yet Adopted In February 2018, the FASB issued authoritative guidance regarding the reclassification of certain stranded tax effects from accumulated other comprehensive income to retained earnings as a result of the change in tax rates related to the Tax Cuts and Jobs Act. The guidance is effective for fiscal periods beginning after December 15, 2018, with early adoption permitted in any interim period. The guidance should be applied either in the period of adoption or retrospectively. Kforce is currently evaluating the potential impact on the consolidated financial statements. In August 2017, the FASB issued authoritative guidance targeting improvements to accounting for hedging activities by simplifying the rules around hedge accounting and improving the disclosure requirements. The guidance is effective for annual periods beginning after December 15, 2018, with early adoption permitted in any interim period. The hedge accounting guidance should be implemented using a modified retrospective approach for any hedges that exist on the date of adoption, while the presentation and disclosure requirements must be applied prospectively. Kforce is currently evaluating the potential impact on the consolidated financial statements. In June 2016, the FASB issued authoritative guidance on accounting for credit losses on financial instruments, including trade receivables. The guidance requires the application of a current expected credit loss model, which measures credit losses based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts. The guidance is effective for annual periods beginning after December 15, 2019, with early adoption permitted no sooner than annual periods beginning after December 15, 2018. The guidance requires companies to apply the requirements using a modified retrospective approach. Kforce is currently evaluating the potential impact on the consolidated financial statements. In February 2016, the FASB issued authoritative guidance regarding the accounting for leases. The guidance is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods, and early adoption is permitted. The guidance requires companies to apply the requirements retrospectively to all prior periods presented, including interim periods. Kforce elected not to adopt this standard early. Kforce anticipates that the adoption of this standard will have a significant impact to the consolidated balance sheet as it will result in recording our operating leases as a right-of-use asset and corresponding lease liability. Kforce continues to assess all potential impacts of the standard, especially with respect to disclosures.

Segment Reporting [Abstract]
Reportable Segments	Reportable Segments Kforce provides services through the following segments: (1) Technology (“Tech”); (2) Finance and Accounting (“FA”); and (3) Government Solutions (“GS”). Historically, and for the three months ended March 31, 2018 and 2017 , we have reported sales and gross profit information on a segment basis. Total assets, liabilities and operating expenses are not reported separately by segment as our operations are largely combined. The following table provides information concerning the operations of our segments (in thousands): Tech FA GS Total Three Months Ended March 31, 2018 Revenue $ 236,497 $ 80,944 $ 28,852 $ 346,293 Gross profit $ 65,348 $ 27,161 $ 7,679 $ 100,188 Operating expenses 87,939 Income before income taxes $ 12,249 2017 Revenue $ 222,045 $ 87,295 $ 24,652 $ 333,992 Gross profit $ 61,100 $ 28,655 $ 7,380 $ 97,135 Operating expenses 87,913 Income before income taxes $ 9,222

Revenue Recognition

Revenue Recognition	3 Months Ended

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition We adopted Topic 606 using the modified retrospective transition method for all contracts that were not completed as of January 1, 2018. Due to the cumulative impact of adopting Topic 606, we recorded a reduction to the opening balance of retained earnings of $0.2 million , net of tax, as of January 1, 2018 with the offset recorded as a contract liability. The adjustment is related to a change in the revenue recognition pattern for the performance obligations under certain GS contracts where a contract provides our customer with a material right to a future discount and standard warranty revenues related to our product business. As of and for the three months ended March 31, 2018 , the unaudited condensed consolidated financial statements were not materially impacted as a result of the application of Topic 606 compared to Topic 605. Revenue Recognition All of our revenue and trade receivables are generated from contracts with customers and substantially all of our revenues are derived from U.S. domestic operations. The following section describes the accounting policies that we believe have significant judgments, or changes in judgment, as a result of adopting Topic 606. Revenue is recognized when control of the promised goods or services is transferred to our customers at an amount that reflects the consideration to which we expect to be entitled to in exchange for those goods or services. Revenue is recorded net of sales or other transaction taxes collected from clients and remitted to taxing authorities. For substantially all of our revenue transactions, we have determined that gross reporting of revenues as a principal versus net as an agent is the appropriate accounting treatment because Kforce: (i) is primarily responsible for fulfilling the promise to provide the specified good or service to the customer, (ii) has discretion in selecting and assigning the temporary workers to particular jobs and establishing the billing rate, and (iii) bears the risk and rewards of the transaction including credit risk if the customer fails to pay for services performed. Flex Revenue Flex revenue is recognized as the temporary staffing services are provided by our consultants at the contractually established bill rates, net of applicable variable consideration. Reimbursements of travel and out-of-pocket expenses ("billable expenses") are also recorded within Flex revenue when incurred and the equivalent amount of expense is recorded in Direct costs in the Unaudited Condensed Consolidated Statements of Operations and Comprehensive Income. Certain temporary staffing services are provided under time-and-material and fixed-price arrangements. For time-and-materials contracts, we recognize revenue in the amount of consideration to which we have the right to invoice when it corresponds directly to the services transferred to the customer satisfied over time. For fixed-price contracts which are frequently utilized in our GS segment, revenues are recognized using the input method based on costs incurred as a proportion of estimated total costs. Incurred costs represent work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. Management uses significant judgments when estimating the total labor hours expected to complete the contract performance obligation. Direct Hire Revenue Direct Hire revenue is recognized at the agreed upon rate when the performance obligation is considered complete. Our policy requires the following criteria to be met in order for the performance obligation to be considered complete: (1) the candidate accepted the position; (2) the candidate resigned from their current employer; and (3) the agreed upon start date falls within the following month. Since the client has accepted the candidate and can direct the use of and obtains the significant risk and rewards of the placement, we consider this point as the transfer of control to our client. Product Revenue Revenue for our product business, which is a component of our GS segment, is recognized after the transfer of control to the customer, which typically occurs upon delivery. Variable Consideration Transaction prices for Flex revenue include variable consideration such as customer rebates and discounts. Management evaluates the facts and circumstances of each contract to estimate the variable consideration using the most likely amount method and based on management’s expectation of the volume of services to be provided over the applicable period. Direct Hire revenue is recorded net of a fallout reserve. Direct Hire fallouts occur when a candidate does not remain employed with the client through the respective contingency period (typically 90 days or less). Management uses the expected value method to estimate the fallout reserve based on a combination of past experience and current trends. Our policy is to include the variable consideration in the transaction price if it is probable that a significant future reversal will not occur. These reserve accruals are recorded in the same period that the related revenue is recognized, resulting in a reduction of revenue with the offset recorded as an other accrued liability in the unaudited condensed consolidated financial statements. Payment Terms Our payment terms and conditions vary by arrangement, although terms are typically less than 90 days . Generally the timing between the satisfaction of the performance obligation and the payment is not significant and we currently do not have any significant financing components. We record a contract liability when we receive consideration from a customer prior to transferring goods or services to the customer or if we have an unconditional right and services have been performed. Cost of Services Direct costs are composed of all related costs of employment for consultants, including compensation, payroll taxes, certain fringe benefits and subcontractor costs. Direct costs exclude depreciation and amortization expense (except for the product revenue), which is presented on a separate line in the accompanying Unaudited Condensed Consolidated Statements of Operations and Comprehensive Income. Associate and field management compensation, payroll taxes and fringe benefits are included in selling, general and administrative expenses (“SG&A”), along with other customary costs such as administrative and corporate compensation. We generally expense sales commissions and any other incremental costs of obtaining a contract as incurred because the amortization period would be less than one year. Trade Receivables and Related Reserves Trade receivables are recorded net of reserves for doubtful accounts and revenue adjustments.The allowance for doubtful accounts is determined based on factors including recent write-off and delinquency trends, a specific analysis of significant receivable balances that are past due, the concentration of trade receivables among clients and higher-risk sectors, and the current state of the U.S. economy. Trade receivables are written off after all reasonable collection efforts have been exhausted. Under Topic 605, the Direct Hire fallout reserve was recorded as a Trade receivables allowance and under Topic 606, it is recorded within Accounts payable and other accrued liabilities in the Unaudited Condensed Consolidated Balance Sheets. As of March 31, 2018 and December 31, 2017 , the Direct Hire fallout reserve was $0.5 million . Unsatisfied Performance Obligations We do not disclose the value of unsatisfied performance obligations for contracts if either the original expected length is one year or less or if revenue is recognized at the amount to which we have the right to invoice for services performed. Disaggregation of Revenue The following table provides information about disaggregated revenue by segment and revenue type for the three months ended March 31, 2018 and 2017 (in thousands): Tech FA GS Total 2018 Revenue by type: Flex revenue $ 231,496 $ 74,550 $ 26,771 $ 332,817 Direct Hire revenue 5,001 6,394 — 11,395 Product revenue — — 2,081 2,081 Total Revenue $ 236,497 $ 80,944 $ 28,852 $ 346,293 2017 Revenue by type: Flex revenue $ 216,886 $ 80,949 $ 21,497 $ 319,332 Direct Hire revenue 5,159 6,346 — 11,505 Product revenue — — 3,155 3,155 Total Revenue $ 222,045 $ 87,295 $ 24,652 $ 333,992 GS Flex revenue includes 40.6% and 28.9% of revenue recognized from fixed-price contracts for the three months ended March 31, 2018 and 2017 , respectively. Contract Balances The following table presents changes in contract liabilities for the three months ended March 31, 2018 (in thousands): Beginning Balance Additions Deductions Ending Balance Contract liabilities $ 740 $ 871 $ (669 ) $ 942 We recognize the contract liability as revenue after we have transferred control of the goods or services to the customer, which is represented as deductions in the table above. Contract liabilities are recorded within Accounts payable and other accrued liabilities if expected to be recognized in less than one year and Other long term liabilities, if over one year, in the Unaudited Condensed Consolidated Balance Sheets. As of March 31, 2018 , we expect to recognize the revenue from contract liabilities as follows: $0.5 million in 2018 and $0.1 million for each of the years ended 2019, 2020, 2021 and 2022.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note D - Commitments and Contingencies Employment Agreements Kforce has employment agreements with certain executives that provide for minimum compensation, salary and continuation of certain benefits for a six -month to a three -year period after their employment ends under certain circumstances. Certain of the agreements also provide for a severance payment ranging from one to three times annual salary and one-half to three times average annual bonus if such an agreement is terminated without good cause by Kforce or for good reason by the executive subject to certain post-employment restrictive covenants. At March 31, 2018 , our liability would be approximately $32.4 million if, following a change in control, all of the executives under contract were terminated without good cause by the employer or if the executives resigned for good reason and $13.0 million if, in the absence of a change in control, all of the executives under contract were terminated by Kforce without good cause or if the executives resigned for good reason. As of March 31, 2018 , the accrued severance balance was approximately $0.4 million for two executives. Litigation We are involved in legal proceedings, claims, and administrative matters that arise in the ordinary course of business. We have made accruals with respect to certain of these matters, where appropriate, that are reflected in our unaudited condensed consolidated financial statements but are not, individually or in the aggregate, considered material. For other matters for which an accrual has not been made, we have not yet determined that a loss is probable or the amount of loss cannot be reasonably estimated. While the ultimate outcome of the matters cannot be determined, we currently do not expect that these proceedings and claims, individually or in the aggregate, will have a material effect on our financial position, results of operations or cash flows. The outcome of any litigation is inherently uncertain, however, and if decided adversely to us, or if we determine that settlement of particular litigation is appropriate, we may be subject to liability that could have a material adverse effect on our financial position, results of operations or cash flows. Kforce maintains liability insurance in amounts and with such coverage and deductibles as management believes is reasonable. The principal liability risks that Kforce insures against are workers’ compensation, personal injury, bodily injury, property damage, directors’ and officers’ liability, errors and omissions, cyber liability, employment practices liability and fidelity losses. There can be no assurance that Kforce’s liability insurance will cover all events or that the limits of coverage will be sufficient to fully cover all liabilities.

Credit Facility	Credit Facility On May 25, 2017, the Firm entered into a credit agreement with Wells Fargo Bank, National Association, as administrative agent, Wells Fargo Securities, LLC, as lead arranger and bookrunner, Bank of America, N.A., as syndication agent, Regions Bank and BMO Harris Bank, N.A., as co-documentation agents, and the lenders referred to therein (the “Credit Facility”). Under the Credit Facility, the Firm has a maximum borrowing capacity of $300.0 million , which may, subject to certain conditions and the participation of the lenders, be increased up to an aggregate additional amount of $150.0 million (the “Commitment”), which will be available to the Firm in the form of revolving credit loans, swingline loans and letters of credit. Letters of credit and swingline loans under the Credit Facility are subject to sublimits of $10.0 million . The maturity date of the Credit Facility is May 25, 2022. Borrowings under the Credit Facility are secured by substantially all of the tangible and intangible assets of the Firm, excluding the Firm’s corporate headquarters and certain other designated executed collateral. Revolving credit loans under the Credit Facility bear interest at a rate equal to (a) the Base Rate (as described below) plus the Applicable Margin (as described below) or (b) the LIBOR Rate plus the Applicable Margin. Swingline loans under the Credit Facility bear interest at a rate equal to the Base Rate plus the Applicable Margin. The Base Rate is the highest of: (i) the Wells Fargo Bank, National Association prime rate, (ii) the federal funds rate plus 0.50% or (iii) one-month LIBOR plus 1.00% , and the LIBOR Rate is reserve-adjusted LIBOR for the applicable interest period, but not less than zero . The Applicable Margin is based on the Firm’s total leverage ratio. The Applicable Margin for Base Rate loans ranges from 0.25% to 0.75% and the Applicable Margin for LIBOR Rate loans ranges from 1.25% to 1.75% . The Firm will pay a quarterly non-refundable commitment fee equal to the Applicable Margin on the average daily unused portion of the Commitment (swingline loans do not constitute usage for this purpose). The Applicable Margin for the commitment fee is based on the Firm’s total leverage ratio and ranges between 0.20% and 0.35% . The Firm is subject to certain affirmative and negative covenants including (but not limited to), the maintenance of a fixed charge coverage ratio of no less than 1.25 to 1.00 and the maintenance of a total leverage ratio of no greater than 3.25 to 1.00. The numerator in the fixed charge coverage ratio is defined pursuant to the Credit Facility as earnings before interest expense, income taxes, depreciation and amortization, stock-based compensation expense and other permitted items pursuant to our Credit Facility (disclosed as “Consolidated EBITDA”), less cash paid for capital expenditures, income taxes and dividends. The denominator is defined as Kforce’s fixed charges such as interest expense and principal payments paid or payable on outstanding debt other than borrowings under the Credit Facility. The total leverage ratio is defined pursuant to the Credit Facility as total indebtedness divided by Consolidated EBITDA. Our ability to make distributions or repurchases of equity securities could be limited if an event of default has occurred. Furthermore, our ability to repurchase equity securities could be limited if (a) the total leverage ratio is greater than 2.75 to 1.00 and (b) the Firm’s availability, inclusive of unrestricted cash, is less than $25.0 million . As of March 31, 2018 , Kforce was not limited in making distributions and executing repurchases of our equity securities. As of March 31, 2018 and December 31, 2017 , $123.2 million and $116.5 million was outstanding, respectively, and $173.6 million and $180.3 million was available under the Credit Facility, respectively, subject to the covenants described above. Kforce had $3.2 million of outstanding letters of credit at March 31, 2018 and December 31, 2017 which, pursuant to the Credit Facility, reduces the availability.

Retirement Benefits [Abstract]
Employee Benefit Plans	Employee Benefit Plans Deferred Compensation Plans The Firm maintains various non-qualified deferred compensation plans, pursuant to which eligible management and highly compensated key employees, as defined by IRS regulations, may elect to defer all or part of their compensation to later years. These amounts are classified in Accounts payable and other accrued liabilities if payable within the next year or in Other long-term liabilities if payable after the next year or upon retirement or termination of employment in the accompanying Unaudited Condensed Consolidated Balance Sheets. At March 31, 2018 and December 31, 2017 , amounts related to the deferred compensation plans included in Accounts payable and other accrued liabilities were $1.9 million and $2.9 million, respectively, and $28.6 million and $28.9 million were included in Other long-term liabilities, respectively, in the Unaudited Condensed Consolidated Balance Sheets. Kforce maintains a Rabbi Trust and holds life insurance policies on certain individuals to assist in the funding of the deferred compensation liability. If necessary, employee distributions are funded through proceeds from the sale of assets held within the Rabbi Trust. The balance of the assets within the Rabbi Trust, including the cash surrender value of the Company-owned life insurance policies, was $31.3 million and $31.4 million as of March 31, 2018 and December 31, 2017 , respectively, and is included in Other assets, net in the accompanying Unaudited Condensed Consolidated Balance Sheets. Supplemental Executive Retirement Plan Kforce maintains a Supplemental Executive Retirement Plan (“SERP”) for the benefit of certain executive officers. The primary goals of the SERP are to create an additional wealth accumulation opportunity, restore lost qualified pension benefits due to government limitations and retain our covered executive officers. The SERP is a non-qualified benefit plan and does not include elective deferrals of covered executive officers’ compensation. The following table presents the components of net periodic benefit cost (in thousands): Three Months Ended March 31, 2018 2017 Service cost $ 338 $ 80 Interest cost 117 134 Net periodic benefit cost $ 455 $ 214 The service cost is recorded in SG&A and the interest cost is recorded in Other expense, net in the accompanying Unaudited Condensed Consolidated Statements of Operations and Comprehensive Income. The projected benefit obligation as of March 31, 2018 and December 31, 2017 was $14.9 million and $14.4 million, respectively, and is recorded in Other long-term liabilities in the accompanying Unaudited Condensed Consolidated Balance Sheets. There is no requirement for Kforce to fund the SERP and, as a result, no contributions were made to the SERP during the three months ended March 31, 2018 . Kforce does no t currently anticipate funding the SERP during the year ended December 31, 2018 .

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock Incentive Plans	Stock Incentive Plans On April 18, 2017, the Kforce shareholders approved the 2017 Stock Incentive Plan (“2017 Plan”). The 2017 Plan allows for the issuance of stock options, stock appreciation rights, stock awards (including restricted stock awards (“RSAs”) and restricted stock units (“RSUs”)) and other stock-based awards. The aggregate number of shares of common stock that are subject to awards under the 2017 Plan is approximately 3.0 million shares. The 2017 Plan terminates on April 18, 2027. Prior to the effective date of the 2017 Plan, the Company granted stock awards to eligible participants under our 2016 Stock Incentive Plan and 2013 Stock Incentive Plan (collectively the “Prior Plans”). As of the effective date of the 2017 Plan, no additional awards may be granted pursuant to the Prior Plans; however, awards outstanding as of the effective date will continue to vest in accordance with the terms of the Prior Plans. During the three months ended March 31, 2018 and 2017 , stock-based compensation expense was $2.3 million and $2.1 million , respectively. Restricted Stock Restricted stock (including RSAs and RSUs) are granted to executives and management either: (1) for awards related to Kforce’s annual long-term incentive (“LTI”) compensation program or (2) as part of a compensation package in order to retain directors, executives and management. The LTI award amounts are generally based on total shareholder return performance goals, which are established by Kforce’s Compensation Committee during the first quarter of the year of performance. Restricted stock granted during the three months ended March 31, 2018 will vest over a period between five to ten years , with equal vesting annually. RSAs contain the same voting rights as other common stock as well as the right to forfeitable dividends in the form of additional RSAs at the same rate as the cash dividend on common stock and containing the same vesting provisions as the underlying award. RSUs contain no voting rights, but have the right to forfeitable dividend equivalents in the form of additional RSUs at the same rate as the cash dividend on common stock and containing the same vesting provisions as the underlying award. The distribution of shares of common stock for each RSU, pursuant to the terms of the Kforce Inc. Director’s Restricted Stock Unit Deferral Plan, can be deferred to a date later than the vesting date if an appropriate election was made. In the event of such deferral, vested RSUs have the right to dividend equivalents. The following table presents the restricted stock activity for the three months ended March 31, 2018 (in thousands, except per share amounts): Number of Restricted Stock Weighted Average Total Intrinsic Outstanding as of December 31, 2017 1,355 $ 22.67 Granted 73 $ 26.66 Forfeited (9 ) $ 21.85 Vested (6 ) $ 17.78 $ 169 Outstanding as of March 31, 2018 1,413 $ 22.90 As of March 31, 2018 , total unrecognized stock compensation expense related to restricted stock was $27.0 million , which will be recognized over a weighted average remaining period of 4.2 years.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instrument and Hedging Activity	Derivative Instrument and Hedging Activity Kforce is exposed to interest rate risk as a result of our corporate borrowing activities. The Firm uses an interest rate swap derivative as a risk management tool to mitigate the potential impact of interest rate risk on our financial results. On April 21, 2017, Kforce entered into a forward-starting interest rate swap agreement with Wells Fargo Bank, N.A. (the “Swap”). The Swap was effective May 31, 2017 and matures April 29, 2022. The Swap rate is 1.81% , which is added to our interest rate margin to determine the fixed rate that the Firm will pay to the counterparty during the term of the Swap based on the notional amount of the Swap. The notional amount of the Swap is $65.0 million for the first three years and decreases to $25.0 million for years four and five. The Swap has been designated as a cash flow hedge and was effective as of March 31, 2018 . The change in the fair value of the Swap was recorded as a component of Accumulated other comprehensive income in the Unaudited Condensed Consolidated Balance Sheets. As of March 31, 2018 and December 31, 2017 , the fair value of the Swap was $1.2 million and $0.5 million asset, respectively.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Kforce’s interest rate swap is measured at fair value using readily observable inputs, such as the LIBOR interest rate, which are considered to be Level 2 inputs. The Swap is recorded in Other assets, net within the accompanying Unaudited Condensed Consolidated Balance Sheets. Refer to Note J - “Derivative Instrument and Hedging Activity” for a complete discussion of the Firm’s derivative instrument. Our contingent consideration liability relates to a non-significant business acquisition within our GS segment, which is measured on a recurring basis and recorded at fair value, using the discounted cash flow method. The inputs used to calculate the fair value of the contingent consideration liability are considered to be Level 3 inputs due to the lack of relevant market activity and significant management judgment. An increase in future cash flows may result in a higher estimated fair value while a decrease in future cash flows may result in a lower estimated fair value of the contingent consideration liability. Remeasurements to fair value are recorded in Other expense, net within the accompanying Unaudited Condensed Consolidated Statements of Operations and Comprehensive Income. There was no activity in our recurring Level 3 fair value measurements for the three months ended March 31, 2018. The contingent consideration liability is recorded in Other long-term liabilities within the accompanying Unaudited Condensed Consolidated Balance Sheets. Certain assets, in specific circumstances, are measured at fair value on a non-recurring basis utilizing Level 3 inputs such as goodwill, other intangible assets and other long-lived assets. For these assets, measurement at fair value in periods subsequent to their initial recognition would be applicable if one or more of these assets were determined to be impaired. The estimated fair values as of March 31, 2018 and December 31, 2017 were as follows (in thousands): Assets/(Liabilities) Measured at Fair Value: Asset/(Liability) Quoted Prices in Significant Significant As of March 31, 2018 Recurring basis: Interest rate swap derivative instrument $ 1,171 $ — $ 1,171 $ — Contingent consideration liability $ (191 ) $ — $ — $ (191 ) As of December 31, 2017 Recurring basis: Interest rate swap derivative instrument $ 479 $ — $ 479 $ — Contingent consideration liability $ (191 ) $ — $ — $ (191 ) There were no transfers into or out of Level 1, 2 or 3 assets or liabilities during the three months ended March 31, 2018 .

Summary of Significant Accoun20

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2018
Accounting Policies [Abstract]
Basis of Presentation	The unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC regarding interim financial reporting. Accordingly, certain information and footnotes normally required by U.S. GAAP for complete financial statements have been condensed or omitted pursuant to those rules and regulations, although Kforce believes that the disclosures made are adequate to make the information not misleading. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our 2017 Annual Report on Form 10-K. In management’s opinion, the accompanying unaudited condensed consolidated financial statements reflect all adjustments considered necessary for a fair presentation. The Unaudited Condensed Consolidated Balance Sheet as of December 31, 2017 was derived from our audited Consolidated Balance Sheet as of December 31, 2017 , as presented in our 2017 Annual Report on Form 10-K. Our quarterly operating results are affected by the number of billing days in a particular quarter, the seasonality of our clients’ businesses and increased holiday and vacation days taken. In addition, we typically experience an increase in costs in the first quarter of each fiscal year as a result of certain U.S. state and federal employment tax resets, which negatively impacts our gross profit and overall profitability. The results of operations for any interim period may be impacted by these factors and are not necessarily indicative of, nor comparable to, the results of operations for a full year.
Principles of Consolidation	The unaudited condensed consolidated financial statements include the accounts of Kforce Inc. and its subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. References in this document to “Kforce,” “the Company,” “we,” “the Firm,” “management,” “our” or “us” refer to Kforce Inc. and its subsidiaries, except where the context indicates otherwise.
Use of Estimates	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The most important of these estimates and assumptions relate to the following: revenue transaction prices; allowance for doubtful accounts; income taxes; self-insured liabilities for workers’ compensation and health insurance; obligations for pension plans and goodwill and any related impairment. Although these and other estimates and assumptions are based on the best available information, actual results could be materially different from these estimates.
Earnings per Share	Basic earnings per share is computed as net income divided by the weighted average number of common shares outstanding (“WASO”) during the period. WASO excludes unvested shares of restricted stock. Diluted earnings per share is computed by dividing net income by diluted WASO. Diluted WASO includes the dilutive effect of potentially dilutive securities such as unvested shares of restricted stock using the treasury stock method, except where the effect of including potential common shares would be anti-dilutive.
New Accounting Standards	Recently Adopted Accounting Standards In May 2014, the FASB issued authoritative guidance regarding revenue from contracts with customers, which specifies that revenue should be recognized when control of the promised goods or services is transferred to our customers at an amount that reflects the consideration to which we expect to be entitled to in exchange for those goods or services. The amended guidance (“Topic 606”) is effective for annual and interim reporting periods beginning after December 15, 2017. We adopted this new standard effective January 1, 2018, using the modified retrospective transition method with a cumulative adjustment to the opening balance of retained earnings. The comparative information continues to be reported under the accounting standards in effect for the period presented ("Topic 605"). Refer to Note C - "Revenue Recognition" for additional accounting policy and transition disclosures. Accounting Standards Not Yet Adopted In February 2018, the FASB issued authoritative guidance regarding the reclassification of certain stranded tax effects from accumulated other comprehensive income to retained earnings as a result of the change in tax rates related to the Tax Cuts and Jobs Act. The guidance is effective for fiscal periods beginning after December 15, 2018, with early adoption permitted in any interim period. The guidance should be applied either in the period of adoption or retrospectively. Kforce is currently evaluating the potential impact on the consolidated financial statements. In August 2017, the FASB issued authoritative guidance targeting improvements to accounting for hedging activities by simplifying the rules around hedge accounting and improving the disclosure requirements. The guidance is effective for annual periods beginning after December 15, 2018, with early adoption permitted in any interim period. The hedge accounting guidance should be implemented using a modified retrospective approach for any hedges that exist on the date of adoption, while the presentation and disclosure requirements must be applied prospectively. Kforce is currently evaluating the potential impact on the consolidated financial statements. In June 2016, the FASB issued authoritative guidance on accounting for credit losses on financial instruments, including trade receivables. The guidance requires the application of a current expected credit loss model, which measures credit losses based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts. The guidance is effective for annual periods beginning after December 15, 2019, with early adoption permitted no sooner than annual periods beginning after December 15, 2018. The guidance requires companies to apply the requirements using a modified retrospective approach. Kforce is currently evaluating the potential impact on the consolidated financial statements. In February 2016, the FASB issued authoritative guidance regarding the accounting for leases. The guidance is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods, and early adoption is permitted. The guidance requires companies to apply the requirements retrospectively to all prior periods presented, including interim periods. Kforce elected not to adopt this standard early. Kforce anticipates that the adoption of this standard will have a significant impact to the consolidated balance sheet as it will result in recording our operating leases as a right-of-use asset and corresponding lease liability. Kforce continues to assess all potential impacts of the standard, especially with respect to disclosures.
