Time-and-materials contract
Time-and-Materials (T&M) contract
A time-and-materials (T&M) contract pays fixed hourly labor rates plus the cost of materials. It is used when the extent or duration of work can't be estimated with confidence, and it requires government oversight because the contractor's profit rises with hours.
What it is
Labor is billed at negotiated fixed hourly rates that include wages, overhead, and profit; materials are billed at cost. A labor-hour contract is the same without the materials element.
Why it exists
It handles work where you genuinely cannot forecast the level of effort at the outset — but because more hours mean more revenue, the FAR treats T&M as a last resort requiring active surveillance.
Who it applies to
Contractors on services with uncertain scope. A ceiling price caps the government's exposure, and the contractor works at risk beyond it.
Frequently asked
What is a time-and-materials contract?
A time-and-materials contract pays fixed hourly labor rates plus materials at cost. It is used when the level of effort can't be estimated confidently up front, and because the contractor's revenue grows with hours worked, it requires close government oversight and a ceiling price.
