Fixed-Price Incentive Fee Contract (FPIF)

A Fixed-Price Incentive Fee (FPIF) contract establishes a target cost and target profit with a ceiling price, sharing cost savings and overruns between the government and contractor through a formula, incentivizing the contractor to control costs while protecting the government with a maximum price.

What is a Fixed-Price Incentive Fee Contract?

FPIF is defined in FAR 16.403. It is used when a more definitive fixed price cannot be established, but where there is enough knowledge to establish a target and ceiling. The contract structure contains four key elements:

• Target cost: the agreed estimate of what performance should cost
• Target profit: the profit the contractor earns if actual costs equal target cost
• Ceiling price: the absolute maximum the government will pay (typically 115-135% of target cost)
• Share ratio: how cost savings and overruns are divided between the parties

The share ratio is expressed as a government/contractor split. For example, a 75/25 share ratio means: for every dollar of cost savings below target cost, the contractor keeps $0.25 in additional profit; for every dollar of cost overrun above target cost, the contractor absorbs $0.25.

Working through the numbers:

• Target cost: $10M | Target profit: $1M | Target price: $11M
• Ceiling price: $13M (130% of target cost)
• Share ratio: 70/30 (government/contractor)

If actual costs = $9M (saving $1M from target):

• Contractor profit = $1M (target) + $300,000 (30% × $1M savings) = $1.3M
• Final price = $9M + $1.3M = $10.3M

If actual costs = $12M (overrun of $2M from target):

• Contractor bears 30% of $2M overrun = $600,000 loss to profit
• Contractor profit = $1M - $600,000 = $400,000
• Final price = $12M + $400,000 = $12.4M (below ceiling)

If actual costs exceed the point of total assumption (the cost at which the contractor's adjusted profit hits zero), costs above that point are the contractor's sole responsibility up to the ceiling.

Why FPIF matters for government contractors

FPIF contracts are common in defense programs where requirements are fairly well-defined but some cost uncertainty exists. The share ratio creates a genuine financial incentive for cost efficiency, unlike a pure cost-plus contract where the contractor is paid all costs regardless of efficiency. Understanding share ratio math is essential for pricing FPIF bids: setting the target cost too low to appear competitive, then hoping to recover through overruns up to the ceiling, is a high-risk strategy. The point of total assumption calculation tells you exactly where your cost overrun exposure becomes 100% your problem.

Example

The Navy awards an FPIF contract to develop a sonar processing system. Target cost: $15M, target profit: $1.5M, ceiling: $19.5M, share ratio 80/20. The contractor's program manager tracks actual costs monthly against the target. At 60% completion, they are running 5% over target. The program manager implements cost controls, reducing material costs and reusing software components. Final actual cost: $15.6M (4% overrun). Contractor's final profit: $1.5M - 20% × $600K overrun = $1.5M - $120K = $1.38M. The contractor still earned $1.38M profit, less than target but far better than if they had ignored the share ratio incentive.

Frequently Asked Questions

What is the "point of total assumption" in an FPIF contract?

The point of total assumption (PTA) is the cost level at which the contractor's profit is fully consumed by overruns, and any additional costs are the contractor's sole responsibility up to the ceiling price. Above the PTA, the effective share ratio becomes 100% contractor. Contractors must monitor their PTA carefully, once you cross it, cost control becomes existential.

When should a contractor prefer FPIF over FFP?

FPIF is preferable to FFP when there is genuine cost uncertainty that makes a fixed price risky, but you have enough knowledge to establish a reasonable target. FFP is preferable when requirements are fully defined and you are confident in your cost estimate, then any efficiency you generate is entirely yours rather than shared.

What is an FPIF with successive target incentives?

Some FPIF contracts include successive targets, a target established at contract award and a subsequent target established after more development information is available. The initial target is used for early performance; the revised target replaces it as the basis for the share formula going forward.

How does FPIF differ from CPIF?

Both use share ratios to incentivize cost control. The key difference: FPIF has a ceiling price the government will never exceed (contractor bears 100% of costs above ceiling). In a Cost-Plus Incentive Fee (CPIF) contract, the government reimburses all allowable costs regardless of how high they go, with the fee formula adjusting for overruns. FPIF places more financial risk on the contractor.
