FAR 16.101—General.
Plain-English Summary
FAR 16.101 explains the basic policy framework for choosing among contract types in federal procurement. It covers the availability of a wide range of contract types, the two main factors that distinguish them—how much cost responsibility the contractor assumes and what profit or fee incentive is built in—and the two broad categories of contracts: fixed-price contracts and cost-reimbursement contracts. It also identifies incentive contracts as the middle ground, where the allocation of cost risk and the incentive structure are tailored to the uncertainties of the work. In practice, this section matters because contract type drives risk allocation, pricing behavior, contractor motivation, and the Government’s exposure to cost growth or savings. It is the starting point for understanding why a contracting officer selects one structure over another and why contractors must evaluate not just the price, but also the risk and reward mechanics of the deal.
Key Rules
Wide Contract-Type Flexibility
The Government and contractors may use a broad selection of contract types to match the needs of the acquisition. The purpose is to provide flexibility for the large variety and volume of supplies and services agencies buy.
Cost Responsibility Varies
Contract types differ based on how much responsibility the contractor assumes for performance costs and when that responsibility applies. At one end, the contractor bears most or all cost risk; at the other, the Government bears much more of the cost risk.
Incentives Differ by Type
Contract types also differ in the amount and nature of profit or fee incentives. Some structures reward the contractor for meeting or exceeding standards or goals, while others provide a fixed fee with little or no performance-based upside.
Two Main Categories
FAR groups contract types into fixed-price contracts and cost-reimbursement contracts. These categories provide the basic framework for understanding how payment, risk, and profit are allocated.
Fixed-Price End of Spectrum
Firm-fixed-price is the most contractor-risk-heavy fixed-price type, with the contractor responsible for performance costs and any resulting profit or loss. It represents the far end of the fixed-price category.
Cost-Reimbursement End of Spectrum
Cost-plus-fixed-fee is the most Government-risk-heavy cost-reimbursement type, with the contractor bearing minimal performance-cost responsibility and the fee fixed in advance. It represents the far end of the cost-reimbursement category.
Incentive Contracts Bridge the Gap
Incentive contracts sit between fixed-price and cost-reimbursement structures. They adjust the contractor’s cost responsibility and profit or fee opportunity to fit the uncertainties of the work.
Responsibilities
Contracting Officer
Select a contract type that matches the acquisition’s uncertainties, risk profile, and incentive needs. The contracting officer must understand how cost responsibility and profit/fee incentives change across contract types and use that understanding to structure the deal appropriately.
Contractor
Evaluate the contract type to understand the level of cost risk assumed and the potential profit or fee structure. The contractor must price and plan performance based on whether it bears full, partial, or minimal responsibility for performance costs.
Agency
Use contract types as a tool to obtain needed supplies and services efficiently while balancing flexibility, risk, and motivation. The agency must support acquisition strategies that align the contract structure with the nature of the requirement.
Practical Implications
Contract type is not just a formality; it determines who pays when costs rise and who benefits when performance is efficient.
A common pitfall is treating all contracts as if they carry the same risk. In reality, firm-fixed-price and cost-plus-fixed-fee sit at opposite ends of the risk spectrum.
Contractors should not focus only on the stated price or fee; they should analyze how much cost growth they will absorb and whether incentives are strong enough to justify performance risk.
Contracting officers should match the contract type to the uncertainty in the requirement. Using a highly fixed structure for an uncertain effort can lead to inflated pricing, disputes, or poor performance.
Incentive contracts require careful design because the incentive must be tied to meaningful standards or goals; otherwise, the structure may not actually improve performance or control cost.
Official Regulatory Text
(a) A wide selection of contract types is available to the Government and contractors in order to provide needed flexibility in acquiring the large variety and volume of supplies and services required by agencies. Contract types vary according to- (1) The degree and timing of the responsibility assumed by the contractor for the costs of performance; and (2) The amount and nature of the profit incentive offered to the contractor for achieving or exceeding specified standards or goals. (b) The contract types are grouped into two broad categories: fixed-price contracts (see subpart 16.2 ) and cost-reimbursement contracts (see subpart 16.3 ). The specific contract types range from firm-fixed-price, in which the contractor has full responsibility for the performance costs and resulting profit (or loss), to cost-plus-fixed-fee, in which the contractor has minimal responsibility for the performance costs and the negotiated fee (profit) is fixed. In between are the various incentive contracts (see subpart 16.4 ), in which the contractor’s responsibility for the performance costs and the profit or fee incentives offered are tailored to the uncertainties involved in contract performance.
