FAR and DFARS › FAR Part 15: Contracting by Negotiation › Subpart 15.4
FAR 15.402 Pricing policy.
The codified text (eCFR, as of 2026-10-02). Under the Revolutionary FAR Overhaul ↗, agencies follow class deviations with new text for many parts while the formal rules go through the Federal Register: check the solicitation and your contract's clauses, which rule.
In plain English
This section requires contracting officers to buy supplies and services from responsible sources at fair and reasonable prices. To determine price reasonableness, they must obtain certified cost or pricing data when required, or other data as necessary, but not more data than needed. It also says each contract must be priced separately and independently, and prohibits including contingency amounts if the contract already provides for a price adjustment for that contingency.
Applies to: Contracting officers awarding contracts
What it requires
- Purchase supplies and services from responsible sources at fair and reasonable prices.
- Obtain certified cost or pricing data when required by 15.403-4, along with other data as necessary.
- When certified cost or pricing data are not required, obtain other data as necessary, generally following the order of preference.
- Price each contract separately and independently, without using proposed price reductions under other contracts as an evaluation factor or considering losses or profits under other contracts.

The text
Contracting officers shall—
(a) Purchase supplies and services from responsible sources at fair and reasonable prices. In establishing the reasonableness of the offered prices, the contracting officer—
(1) Shall obtain certified cost or pricing data when required by 15.403-4, along with data other than certified cost or pricing data as necessary to establish a fair and reasonable price; or
(2) When certified cost or pricing data are not required by 15.403-4, shall obtain data other than certified cost or pricing data as necessary to establish a fair and reasonable price, generally using the following order of preference in determining the type of data required:
(i) No additional data from the offeror, if the price is based on adequate price competition, except as provided by 15.403-3(b).
(ii) Data other than certified cost or pricing data such as—
(A) Data related to prices (e.g., established catalog or market prices, sales to non-governmental and governmental entities), relying first on data available within the Government; second, on data obtained from sources other than the offeror; and, if necessary, on data obtained from the offeror. When obtaining data from the offeror is necessary, unless an exception under 15.403-1(b)(1) or (2) applies, such data submitted by the offeror shall include, at a minimum, appropriate data on the prices at which the same or similar items have been sold previously, adequate for evaluating the reasonableness of the price.
(B) Cost data to the extent necessary for the contracting officer to determine a fair and reasonable price.
(3) Obtain the type and quantity of data necessary to establish a fair and reasonable price, but not more data than is necessary. Requesting unnecessary data can lead to increased proposal preparation costs, generally extend acquisition lead time, and consume additional contractor and Government resources. Use techniques such as, but not limited to, price analysis, cost analysis, and/or cost realism analysis to establish a fair and reasonable price. If a fair and reasonable price cannot be established by the contracting officer from the analyses of the data obtained or submitted to date, the contracting officer shall require the submission of additional data sufficient for the contracting officer to support the determination of the fair and reasonable price.
(b) Price each contract separately and independently and not—
(1) Use proposed price reductions under other contracts as an evaluation factor; or
(2) Consider losses or profits realized or anticipated under other contracts.
(c) Not include in a contract price any amount for a specified contingency to the extent that the contract provides for a price adjustment based upon the occurrence of that contingency.
