Cost-Plus-Incentive-Fee (CPIF)
What It Is
A cost-plus-incentive-fee (CPIF) contract reimburses allowable costs and pays a fee that varies by formula with the relationship between total allowable cost and target cost. The parties set a target cost, a target fee, a minimum fee, a maximum fee, and a share ratio. If final cost is below target, the fee rises toward the maximum; if above, it falls toward the minimum. It is used on cost-type efforts where a cost-control incentive is meaningful and measurable, sitting between CPFF (no cost incentive) and fixed-price incentive (a hard ceiling).
Who Carries the Risk
Cost risk largely on the government as with all cost-type contracts, but the fee swing gives the contractor a measurable stake in controlling cost between the minimum and maximum fee.
When the Government Uses It
- Development and test efforts where cost outcomes are uncertain but a cost-control incentive can be objectively measured.
- Cost-reimbursement work where the government wants more cost discipline than a fixed-fee contract provides.
- Larger, more complex procurements — rare on small commercial set-asides.
Key Features
| Feature | What It Means |
|---|---|
| Target cost / target fee | The negotiated baseline. Final fee moves off the target fee depending on whether final cost beats or misses target cost. |
| Minimum & maximum fee | The fee can only move within this band, so the incentive is bounded on both ends. |
| Share ratio | How cost under/over-runs translate into fee movement — the contractor's stake in cost outcomes. |
| Accounting & audit | Same as any cost-type contract: an adequate accounting system, FAR Part 31 cost principles, and DCAA audit exposure. |
What It Means for an SDVOSB
CPIF is uncommon for small set-asides, but the prerequisites are the same as any cost-reimbursement work — an adequate accounting system (SF 1408) and the ability to track allowable cost. The fee incentive rewards cost control, which can help a disciplined small prime. Treat the limitations on subcontracting as you would on any cost-type service contract under 13 CFR 125.6, measuring self-performance against the amount paid to you less direct materials.
Common Pitfalls
- Underestimating the accounting and audit overhead a cost-type contract demands relative to fixed-price work.
- Misreading the fee band — the maximum fee caps your upside even if you dramatically beat target cost.
- Assuming the incentive offsets cost risk — the government still owns most cost risk, but your fee, not your costs, is what flexes.
Run the Numbers
Frequently Asked
How is CPIF different from cost-plus-fixed-fee?
On a CPFF contract the fee is a fixed dollar amount that does not change with cost. On a CPIF contract the fee varies by formula between a minimum and maximum fee depending on how final allowable cost compares to a target cost. CPIF gives the contractor a measurable incentive to control cost; CPFF does not.
Is there a ceiling on what the government pays under CPIF?
There is a band on the fee (minimum and maximum fee), but not a hard price ceiling on reimbursed costs the way a fixed-price incentive contract has. The government reimburses allowable costs subject to the funding limits and the Limitation of Cost/Funds clause; only the fee is bounded. That is a key difference from fixed-price incentive contracts, which cap total price.

Contract-type selection is a contracting-officer judgment and the FAR is periodically amended — always confirm the contract type, clauses, and how the limitations on subcontracting are measured against the solicitation and your contracting officer before relying on this.
