Debt Disclosure [Abstract]
Credit Facility	Credit Facility On September 20, 2011, Kforce entered into a Third Amended and Restated Credit Agreement, with a syndicate led by Bank of America, N.A. This was amended on March 30, 2012 through the execution of a Consent and First Amendment, on December 27, 2013 through the execution of a Second Amendment and Joinder, and further amended on December 23, 2014 through the execution of a Third Amendment resulting in a maximum borrowing capacity of $170.0 million, as well as an accordion option of $50.0 million. The maximum borrowings available to Kforce under the Credit Facility are limited to: (a) a revolving Credit Facility of up to $170.0 million (the “Revolving Loan Amount”) and (b) a $15.0 million sub-limit included in the Credit Facility for letters of credit. Available borrowings under the Credit Facility are limited to 85% of the net amount of eligible accounts receivable, plus 85% of the net amount of eligible unbilled accounts receivable, plus 80% of the net amount of eligible employee placement accounts, minus certain minimum availability reserve; provided, that the Firm may, subject to certain conditions, elect to increase the available borrowing limitation based on a percentage of the appraised fair market value of the Firm's corporate headquarters property and/or an additional percentage of net eligible accounts receivable, net eligible unbilled accounts receivable and net eligible employee placement accounts. Borrowings under the Credit Facility are secured by substantially all of the assets of the Firm, excluding the real estate located at the Firm's corporate headquarters in Tampa, Florida, unless the eligible real estate conditions are met. Outstanding borrowings under the Revolving Loan Amount bear interest at a rate of: (a) LIBOR plus an applicable margin based on various factors; or (b) the higher of (1) the prime rate, (2) the federal funds rate plus 0.50% or (3) LIBOR plus 1.25%. Fluctuations in the ratio of unbilled to billed receivables could result in material changes to availability from time to time. Letters of credit issued under the Credit Facility require Kforce to pay a fronting fee equal to 0.125% of the amount of each letter of credit issued, plus a per annum fee equal to the applicable margin for LIBOR loans based on the total letters of credit outstanding. To the extent that Kforce has unused availability under the Credit Facility, an unused line fee is required to be paid on a monthly basis equal to: (a) if the average daily aggregate revolver outstanding are less than 35% of the amount of the commitments, 0.35% or (b) if the average daily aggregate revolver outstanding are greater than 35% of the amount of the commitments, 0.25% times the amount by which the maximum revolver amount exceeded the sum of the average daily aggregate revolver outstanding, during the immediately preceding month or shorter period if calculated for the first month hereafter or on the termination date. Under the Credit Facility, Kforce is subject to certain affirmative and negative covenants including, but not limited to, a fixed charge coverage ratio, which is only applicable in the event that the Firm’s availability under the Credit Facility falls below the greater of (i) 10% of the aggregate amount of the commitment of all of the lenders under the Credit Facility and (ii) $11 million. 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, including the amortization of stock-based compensation expense, less cash paid for capital expenditures. The denominator is defined as Kforce’s fixed charges such as interest expense, principal payments paid or payable on outstanding debt other than borrowings under the Credit Facility, income taxes payable, and certain other payments. This financial covenant, if applicable, requires that the numerator be equal to or greater than the denominator. Also, our ability to make distributions or repurchase equity securities could be limited if the Firm's availability is less than the greater of (i) 12.5% of the aggregate amount of the commitment of all lenders under the Credit Facility or (ii) $20.6 million. Since Kforce had availability under the Credit Facility of $48.5 million as of December 31, 2015, the fixed charge coverage ratio covenant was not applicable nor was Kforce limited in making distributions or repurchases of its equity securities. Kforce believes that it will be able to maintain these minimum availability requirements; however, in the event that Kforce is unable to do so, Kforce could fail the fixed charge coverage ratio, which would constitute an event of default, or could be limited in our ability to make distributions or repurchase equity securities. Kforce believes the likelihood of default is remote. The Credit Facility expires December 23, 2019. As of December 31, 2015 and 2014, $80.5 million and $93.3 million was outstanding under the Credit Facility, respectively. As of February 23, 2016, $88.4 million was outstanding and $43.5 million was available under the Credit Facility.
