Definition

NTE ("Not-to-Exceed") is a ceiling amount on a federal contract that funds or labor cannot exceed without a formal contract modification. The NTE amount is the hard dollar cap — the contractor stops work at the ceiling unless the Contracting Officer issues a bilateral modification raising it. Most common in Time-and-Materials (T&M) and cost-reimbursement contracts (FAR Part 16) where actual costs are not known upfront, but NTE clauses also appear in construction contracts (where they cap labor hours or material quantities for a defined scope) and IDIQ/BPA task orders (where they cap each individual order against the master vehicle ceiling). When you see "NTE $2,500,000" in a solicitation, that is the maximum the contract can pay across its full period of performance, base plus all options.

Where this matters in federal contracting

NTE is a measurement used in federal contract evaluation, source selection, oversight, or performance management. For example: A T&M contract for IT support services has an NTE of $850,000. Once cumulative labor + materials bills hit $850K, the contractor must stop work and request a contract modification — even if the period of performance has not ended. The Contracting Officer can issue a bilateral mod (mutual signature) to raise the NTE, but only if funds are available and the scope justifies it. Unilateral over-runs are not reimbursable. Understanding NTE matters because evaluators use metrics like it to compare proposals quantitatively, score past performance, set award-fee outcomes, and decide who gets the next option year. Contractors who track how NTE is calculated — and what target values look like in their NAICS or service area — write proposals that are concrete and defensible instead of generic and easily dismissed. NTE also has implications for contract administration: getting the calculation methodology wrong post-award is a common source of disputes and contracting-officer modifications. Pair NTE with the related metrics above to see how the federal government composes evaluation criteria into source-selection narratives.
