Not to Exceed (NTE)
Not to Exceed (NTE) is a ceiling established in a federal contract or task order that caps the total amount the government will pay (or the total labor hours the contractor will perform) regardless of actual incurred cost.
What Is Not to Exceed?
A Not to Exceed amount is the maximum dollar value (or labor hour total) the government has obligated under a federal contract or task order. It is not a fixed price; it is a cap.
On a cost-plus-fixed-fee contract, for example, the government reimburses allowable costs up to the NTE; once the cumulative cost reaches the NTE, reimbursement stops. On a time-and-materials contract, the NTE caps the total labor hours the contractor can perform.
NTE ceilings are essential because they convert open-ended cost or hour exposure into a managed financial commitment. Each NTE has a notification threshold (commonly 75 percent or 85 percent) at which the contractor must alert the contracting officer that the ceiling is approaching, giving both parties time to negotiate an increase or replan the work.
Key Characteristics
NTE ceilings have several defining attributes. They establish a hard cap, not a target: the government has no obligation to fund beyond the NTE.
They are tied to specific clauses, primarily FAR 52.232-20 (Limitation of Cost) for fully funded cost contracts, FAR 52.232-22 (Limitation of Funds) for incrementally funded cost contracts, and similar mechanisms for T&M and labor-hour contracts. They impose written notification duties on the contractor at defined percentages of the ceiling.
They convert continued performance beyond the NTE into a contractor-at-risk situation unless the ceiling is formally raised through a contract modification. Each characteristic shapes how the contractor monitors burn rate, communicates with the contracting officer, and protects revenue and reputation.
How It Works in Government Contracting
NTE operates throughout the contract performance cycle. First, the contracting officer establishes the NTE in the contract or task order, typically based on the proposal cost estimate plus management reserve.
Second, the contractor performs work and tracks cumulative incurred cost against the NTE in its accounting system, typically using project job cost codes. Third, when cumulative cost approaches the notification threshold (typically 75 percent or 85 percent), the contractor sends a written Limitation of Cost or Limitation of Funds notice to the contracting officer.
Fourth, the contracting officer evaluates the notice, the remaining scope of work, and the funding posture, then either authorizes an NTE increase through a change order or directs the contractor to stop work at the ceiling. Fifth, if the ceiling is reached without an increase, the contractor stops performance and is not obligated to continue without additional funding. Continuing past the NTE without authorization can result in unrecoverable costs.
Real-World Example
A federal agency awards a $3 million cost-plus-fixed-fee task order for systems engineering support with a twelve-month period of performance. The contractor's labor and ODC burn rate is roughly $250,000 per month.
Cost tracking shows that at month nine, cumulative cost has reached $2.4 million (80 percent of the NTE). The contractor's project manager prepares a Limitation of Cost notice citing FAR 52.232-20 and submits it to the contracting officer with a revised forecast showing the work will exceed $3 million by approximately $400,000 to complete the agreed scope.
The contracting officer reviews the notice, validates the cost data with the technical representative, and issues a contract modification raising the NTE to $3.4 million and obligating the additional funds. The contractor continues performance.
Had the contractor failed to issue the timely notice and continued past the NTE without authorization, the additional $400,000 in costs would not have been reimbursable, and the contractor would have absorbed the loss.
Regulatory Framework
NTE ceilings are governed by FAR Part 32 (Contract Financing), specifically FAR Subpart 32.7 (Contract Funding), and operationalized through FAR 52.232-20 (Limitation of Cost), FAR 52.232-22 (Limitation of Funds), and FAR 52.232-7 (Payments under T&M and Labor-Hour Contracts). FAR 52.232-20 applies to fully funded cost contracts; FAR 52.232-22 applies to incrementally funded cost contracts.
Both clauses establish the contractor's notification duties and the government's lack of obligation to fund beyond the NTE. DFARS adds defense-specific requirements for cost notification on certain procurement types.
Failure to comply with notification requirements can result in cost disallowance and, in extreme cases, can be cited as a deficiency in past performance evaluations. The contractor's accounting system must support burn-rate tracking at the granularity required by the contract's NTE structure.
Why It Matters for Contractors
NTE management is central to federal contract financial discipline. Contractors that exceed an NTE without timely notification absorb the overrun, hurting margins and inviting cost-disallowance audits.
Contractors that hit the NTE without timely notification can be required to stop work mid-contract, damaging the schedule, the customer relationship, and CPARS ratings. NTE management interacts with change orders (the formal mechanism for raising an NTE), with indirect rates (because indirect cost variations affect total cost relative to NTE), with requests for equitable adjustment, and with CDA claims when government-caused delay forces cost overruns. The contractors that handle NTE best treat it as a real-time financial discipline, not a year-end accounting exercise.
Common Misconceptions
NTE is the same as a fixed price.
No. A fixed price is a guaranteed payment regardless of actual cost. An NTE is a cap on a cost-reimbursement or T&M contract; the government pays only actual allowable cost up to the cap, not the full NTE.
The contractor can continue working past the NTE and bill later.
No. Continuing past the NTE without an authorized increase puts the contractor at risk for the entire overrun. The government has no obligation to fund work beyond the ceiling. Costs incurred past the NTE without authorization are typically unrecoverable.
The contracting officer will always raise the NTE on request.
No. The contracting officer evaluates the notice, the remaining scope, and the funding posture. An increase may be authorized, partially authorized, or denied. The contractor must plan for the possibility that the ceiling will not be raised.
Frequently Asked Questions
What is the difference between Limitation of Cost and Limitation of Funds?
FAR 52.232-20 (Limitation of Cost) applies to fully funded cost contracts. FAR 52.232-22 (Limitation of Funds) applies to incrementally funded cost contracts where the government obligates funds in tranches. Both clauses establish the contractor's notification duties and the government's funding cap.
When must the contractor send a Limitation of Cost notice?
When the contractor has reason to believe that cumulative cost will reach the NTE within the next 60 days, or when actual cumulative cost reaches a defined percentage of the NTE (commonly 75 to 85 percent). The notice is in writing and is sent to the contracting officer.
Can the NTE be increased after award?
Yes. The contracting officer can issue a contract modification raising the NTE if funding is available and the additional scope is justified. The modification follows the normal change order process under FAR Part 43.
What happens to costs incurred past the NTE without authorization?
Generally unrecoverable. The contractor absorbs the overrun. The contracting officer has discretion to grant relief in narrow circumstances, but this is not the rule.
