Tradeoff — Best-Value Tradeoff
Also known as: Tradeoff process, best value
What It Is
The best-value tradeoff process, set out in FAR 15.101-1, is used when it may be in the government's interest to make award to other than the lowest-priced offeror or other than the highest technically rated offeror. Under a tradeoff the solicitation states all evaluation factors and significant subfactors that will affect award and their relative importance, and it discloses whether the non-price factors, when combined, are significantly more important than, approximately equal to, or significantly less important than price. The source-selection authority then makes an integrated assessment — comparing proposals against the stated factors and against each other — and may pay a price premium for superior technical merit or past performance when that premium is justified and documented. It is the opposite end of the best-value continuum from LPTA.
When It Applies
- On complex or service-heavy requirements where the quality of the technical approach and the offeror's track record genuinely differentiate proposals.
- On negotiated procurements under FAR Subpart 15.2 — typically an RFP whose Section M states that award will be made on a best-value tradeoff basis.
- Whenever the solicitation says the non-price factors are 'significantly more important than', 'approximately equal to', or otherwise weighted against price.
Key Features
| Feature | What It Means |
|---|---|
| A premium for a better proposal | Award can go to a higher-priced offeror when the added technical merit or past performance is worth the extra cost — the tradeoff and its rationale must be documented. |
| Stated relative importance of factors | FAR 15.304 requires the solicitation to disclose the evaluation factors, significant subfactors, and how they are weighted relative to price. |
| Integrated, comparative judgment | The source-selection authority makes an independent, integrated assessment comparing proposals against the factors and against one another, not a mechanical score. |
| Documented decision | The tradeoff rationale — why the chosen proposal's benefits justify any price premium — must be documented in the source-selection decision. |
What It Means for an SDVOSB
Tradeoff is the process where a strong SDVOSB beats bigger, cheaper competitors. Because the government can pay a premium for a better proposal, your directly relevant past performance, a sharp technical approach, and low-risk staffing can win even when you are not the lowest price. Read Section M (evaluation factors) and Section L (instructions) first and write to the factors in the order and weight the government will actually score — do not bury your discriminators. Use the win-probability estimator to gauge how crowded the field is and the price-to-win calculator to set a price that is competitive without giving away the technical edge that justifies your selection.
How to Win Under It
- Read Section M and Section L first, and structure your proposal to address every factor and subfactor in the stated order and weight.
- Lead with discriminators — relevant past performance, a low-risk technical approach, and concrete benefits the evaluator can point to in a tradeoff.
- Price competitively, but do not race to the bottom; tradeoff rewards value, so protect the strengths that justify your selection.
- Make the evaluator's job easy: map your strengths explicitly to the evaluation factors so the tradeoff rationale writes itself.
Common Pitfalls
- Writing to your strengths instead of to the Section M factors the government will actually score and trade off.
- Assuming the lowest price wins — under tradeoff it does not necessarily, but assuming the highest-rated proposal wins regardless of price is equally wrong.
- Failing to substantiate claimed strengths with evidence, leaving the evaluator nothing concrete to justify a premium.

Frequently Asked
What is the difference between best-value tradeoff and LPTA?
Both sit on the best-value continuum in FAR 15.101, but they pull in opposite directions. Under a best-value tradeoff (FAR 15.101-1) the government may pay more for a better proposal — technical merit and past performance can outweigh price, and a higher-priced offeror can win when the premium is justified. Under lowest-price technically-acceptable, or LPTA (FAR 15.101-2), the government cannot pay a premium for anything above 'acceptable': among proposals rated acceptable on a pass/fail basis, the lowest price wins. Tradeoff rewards quality; LPTA rewards price among the merely acceptable.
Does the lowest-priced offeror lose under a best-value tradeoff?
Not automatically. A best-value tradeoff lets the government pay a premium for superior non-price merit, but it does not require it. The lowest-priced offeror can still win if its proposal is also the best value — and the highest-rated offeror can still lose if its advantages are not worth the extra cost. The source-selection authority must document why the selected proposal represents the best value given the stated relative importance of the factors and price.

Plain-English reference, not legal advice. How a source selection is conducted, and which evaluation method and procedures apply, is set by the specific solicitation, and the FAR is periodically amended — always read the actual solicitation (especially Sections L and M) and confirm its terms with the contracting officer before relying on this.
