FAR 52.216-10—Incentive Fee.
Plain-English Summary
FAR 52.216-10, Incentive Fee, is the standard clause for a cost-plus-incentive-fee (CPIF) contract. It explains how the Government pays the contractor a negotiated fee, how target cost and target fee are defined and adjusted, when the Contracting Officer may withhold or release fee, how equitable adjustments affect target cost and fee, how the fee is calculated above or below target cost, and what costs are excluded from the fee-adjustment formula. It also addresses special treatment for assignments, certain claims, and full contract terminations, and requires the final target cost and adjusted fee to be documented by contract modification. In practice, this clause is the core mechanism that ties contractor profit to cost performance while protecting the Government through fee ceilings/floors, withholding, and adjustment rules. It matters because both parties must track allowable cost, indirect rate settlements, and contract changes carefully to avoid disputes over the final fee. The clause also interacts with other clauses such as Allowable Cost and Payment, Excusable Delays, Government Property, Insurance, and indemnification provisions, so it must be read as part of the whole contract.
Key Rules
Fee is performance-based
The Government pays a fee determined by the contract, not a fixed profit amount. The fee is adjusted based on actual allowable cost relative to target cost, subject to the contract’s incentive formula and fee limits.
Target cost and fee can change
Target cost and target fee are the initially negotiated estimates, but they may be adjusted if the contract is modified or if another clause authorizes an equitable adjustment. Any such change must be reflected in a supplemental agreement.
Contracting Officer may withhold fee
The Contracting Officer may pay less than the scheduled fee if performance or cost suggests the contractor will miss target, and may pay more if the contractor clearly will exceed target fee. The decision is discretionary and based on the CO’s judgment.
Fee reserve is limited
The Government may withhold a reserve of up to 15 percent of the total incentive fee or $100,000, whichever is less, to protect its interests. The clause also sets conditions for releasing 75 percent, and potentially up to 90 percent, of withheld fee based on final indirect rate submission, settlement, and past performance.
Formula rewards underruns and penalizes overruns
The fee increases by a stated participation rate for each dollar that total allowable cost is below target cost, and decreases by that rate for each dollar above target cost. The fee cannot exceed the stated maximum percentage or fall below the stated minimum percentage of target cost.
Certain costs are excluded from fee adjustment
The definition of total allowable cost excludes costs arising from excusable delays, post-negotiation tax or duty changes, required litigation support, certain insurance costs, Government-relieved property risks, and expressly indemnified unusually hazardous or nuclear risks. All other allowable costs are included unless the contract says otherwise.
Assignments and claims can affect fee
The fee is adjusted for allowable cost changes caused by payments made under assignments and by claims excepted from release under the Allowable Cost and Payment clause, but only within the minimum and maximum fee limits.
Termination changes the fee rule
If the contract is terminated in its entirety, the portion of target fee payable is not increased or decreased under the incentive formula. Termination is handled under the contract’s other applicable termination clauses.
Final numbers must be documented
The final total allowable cost and adjusted fee must be set out in a contract modification signed by both the contractor and the Contracting Officer. This creates the official record for payment and closeout.
Clause controls over inconsistent documents
If there is a conflict between this clause and provisioning documents or Government options, the clause governs. This prevents proposal language or option terms from overriding the negotiated CPIF payment rules.
Responsibilities
Contracting Officer
Set the target cost, target fee, participation rate, minimum fee, maximum fee, and fee reserve in the schedule; monitor performance and cost trends; decide whether to withhold, reduce, or increase fee within the clause’s limits; release withheld fee when the required indirect cost proposal, patent and royalty reports, and prior voucher issues are resolved; negotiate and sign equitable adjustments and final fee modifications; and resolve inconsistencies in favor of the contract clause.
Contractor
Perform the work efficiently to manage allowable cost and earn incentive fee; submit accurate cost data, final indirect cost rate proposals, patent and royalty reports, and final vouchers; notify the Government of changes affecting target cost or fee; support equitable adjustments and final fee calculations; and ensure costs claimed for fee adjustment are allowable and properly documented.
Agency/Government
Administer the CPIF arrangement through proper funding, oversight, and contract modification; ensure the clause is used where prescribed; protect the Government’s interest through fee withholding and review of cost submissions; and process final settlements and closeout actions consistent with the clause and related FAR provisions.
Practical Implications
This clause makes cost control directly affect profit, so both sides need tight cost tracking and timely indirect rate settlement. Delays in final rate proposals or final vouchers can delay release of withheld fee.
The fee formula is only as good as the schedule entries. If the participation rate, minimum fee, maximum fee, or reserve are not clearly stated, the contract will be hard to administer and disputes are more likely.
Not every cost overrun or underrun counts the same way. Costs tied to excusable delays, certain tax changes, required litigation support, and other listed exceptions are excluded from the fee-adjustment math, so teams must classify costs carefully.
Contract modifications matter. Any change to scope or any equitable adjustment under another clause should be translated into a written adjustment to target cost and fee, or the final fee calculation may be wrong.
The Contracting Officer has discretion to withhold or release fee, so contractors should not assume the scheduled fee will be paid automatically. Strong performance, clean cost submissions, and prompt closeout support faster release of withheld amounts.
Official Regulatory Text
As prescribed in 16.307 (d) , insert the following clause: Incentive Fee (Jun 2011) (a) General . The Government shall pay the Contractor for performing this contract a fee determined as provided in this contract. (b) Target cost and target fee . The target cost and target fee specified in the Schedule are subject to adjustment if the contract is modified in accordance with paragraph (d) of this clause. (1) "Target cost," as used in this contract, means the estimated cost of this contract as initially negotiated, adjusted in accordance with paragraph (d) of this clause. (2) "Target fee," as used in this contract, means the fee initially negotiated on the assumption that this contract would be performed for a cost equal to the estimated cost initially negotiated, adjusted in accordance with paragraph (d) of this clause. (c) Withholding of payment. (1) Normally, the Government shall pay the fee to the Contractor as specified in the Schedule. However, when the Contracting Officer considers that performance or cost indicates that the Contractor will not achieve target, the Government shall pay on the basis of an appropriate lesser fee. When the Contractor demonstrates that performance or cost clearly indicates that the Contractor will earn a fee significantly above the target fee, the Government may, at the sole discretion of the Contracting Officer, pay on the basis of an appropriate higher fee. (2) Payment of the incentive fee shall be made as specified in the Schedule; provided that the Contracting Officer withholds a reserve not to exceed 15 percent of the total incentive fee or $100,000, whichever is less, to protect the Government’s interest. The Contracting Officer shall release 75 percent of all fee withholds under this contract after receipt of an adequate certified final indirect cost rate proposal covering the year of physical completion of this contract, provided the Contractor has satisfied all other contract terms and conditions, including the submission of the final patent and royalty reports, and is not delinquent in submitting final vouchers on prior years’ settlements. The Contracting Officer may release up to 90 percent of the fee withholds under this contract based on the Contractor’s past performance related to the submission and settlement of final indirect cost rate proposals. (d) Equitable adjustments . When the work under this contract is increased or decreased by a modification to this contract or when any equitable adjustment in the target cost is authorized under any other clause, equitable adjustments in the target cost, target fee, minimum fee, and maximum fee, as appropriate, shall be stated in a supplemental agreement to this contract. (e) Fee payable. (1) The fee payable under this contract shall be the target fee increased by _____ [ Contracting Officer insert Contractor’s participation ] cents for every dollar that the total allowable cost is less than the target cost or decreased by ______ [ Contracting Officer insert Contractor’s participation ] cents for every dollar that the total allowable cost exceeds the target cost. In no event shall the fee be greater than ____________ [ Contracting Officer insert percentage ] percent or less than _________________ [ Contracting Officer insert percentage ] percent of the target cost. (2) The fee shall be subject to adjustment, to the extent provided in paragraph (d) of this clause, and within the minimum and maximum fee limitations in paragraph (e)(1) of this clause, when the total allowable cost is increased or decreased as a consequence of- (i) Payments made under assignments; or (ii) Claims excepted from the release as required by paragraph (h)(2) of the Allowable Cost and Payment clause. (3) If this contract is terminated in its entirety, the portion of the target fee payable shall not be subject to an increase or decrease as provided in this paragraph. The termination shall be accomplished in accordance with other applicable clauses of this contract. (4) For the purpose of fee adjustment, "total allowable cost" shall not include allowable costs arising out of- (i) Any of the causes covered by the Excusable Delays clause to the extent that they are beyond the control and without the fault or negligence of the Contractor or any subcontractor; (ii) The taking effect, after negotiating the target cost, of a statute, court decision, written ruling, or regulation that results in the Contractor’s being required to pay or bear the burden of any tax or duty or rate increase in a tax or duty; (iii) Any direct cost attributed to the Contractor’s involvement in litigation as required by the Contracting Officer pursuant to a clause of this contract, including furnishing evidence and information requested pursuant to the Notice and Assistance Regarding Patent and Copyright Infringement clause; (iv) The purchase and maintenance of additional insurance not in the target cost and required by the Contracting Officer, or claims for reimbursement for liabilities to third persons pursuant to the Insurance Liability to Third Persons clause; (v) Any claim, loss, or damage resulting from a risk for which the Contractor has been relieved of liability by the Government Property clause; or (vi) Any claim, loss, or damage resulting from a risk defined in the contract as unusually hazardous or as a nuclear risk and against which the Government has expressly agreed to indemnify the Contractor. (5) All other allowable costs are included in "total allowable cost" for fee adjustment in accordance with this paragraph (e), unless otherwise specifically provided in this contract. (f) Contract modification . The total allowable cost and the adjusted fee determined as provided in this clause shall be evidenced by a modification to this contract signed by the Contractor and Contracting Officer. (g) Inconsistencies . In the event of any language inconsistencies between this clause and provisioning documents or Government options under this contract, compensation for spare parts or other supplies and services ordered under such documents shall be determined in accordance with this clause.
