Finish the work you promised, spend less than you budgeted, and the difference is yours to keep. That is not an accounting trick. It is the plain text of 2 CFR 200.201(b)(4), the regulation governing the fixed amount award: when the required activities are completed as agreed, “the recipient or subrecipient is entitled to any unexpended funds.” No other federal grant mechanism works this way, and the Office of Management and Budget has proposed shutting it down.

The Clause That Lets You Keep the Leftovers

Under cost reimbursement — the default for most federal money — you spend first, document every dollar, invoice the agency, and return anything you do not use. Your general ledger becomes the deliverable. Under a fixed amount award, the agency and the recipient negotiate a price up front using the cost principles as a guide, then payment is tied to results. The regulation is explicit that there is “no expected routine monitoring of the actual costs incurred,” and that consequently “no financial reporting is required.”

That single sentence is worth more to a small organization than most people realize. It removes the monthly reconciliation, the drawdown justification memo, the variance explanation when a line item runs 12% over, and the year-end unobligated balance report. What replaces it is a performance report and, at closeout, a written certification that the project was completed as agreed.

The surplus rule is the part that gets left out of summaries. If you priced a workforce training cohort at $180,000 and delivered every session for $161,000 because you found a cheaper venue and your instructor rate held, the $19,000 stays with you. Efficiency becomes margin instead of a clawback. That is the opposite incentive from every cost-reimbursement award you have ever administered.

Where This Mechanism Actually Shows Up

These are not theoretical. Agencies use them, and they use them most often at the subaward layer, where 2 CFR 200.333 governs fixed amount subawards issued by a pass-through entity. The thresholds are set agency by agency, which is why the mechanism looks invisible until you read the right policy notice.

The National Institutes of Health, in NOT-OD-25-059, recognizes a prior-approval threshold of $500,000 for fixed amount subawards unless a specific notice of funding opportunity says otherwise. That is a meaningful ceiling — half a million dollars of subaward that can be structured on deliverables rather than timesheets. The National Science Foundation takes a narrower line: its subrecipient management guidance calls fixed-amount subawards “uncommon” and permits them, with prior written approval, only up to the simplified acquisition threshold. NSF also issues fixed amount awards at the prime level, describing them in its proposal and award policy guide as a type that “reduces some of the administrative burden and recordkeeping requirements for both the recipient and NSF.”

The pattern across agencies is consistent: this structure is available where the scope has measurable goals and where credible unit pricing or historical cost data exists to justify the number. Training cohorts, defined technical deliverables, per-participant service counts, survey administration, and equipment installation all fit. Open-ended research does not. If you are scanning federal grant opportunities and a program description talks about deliverables, units served, or milestones rather than allowable cost categories, you are probably looking at a candidate.

The Six Conditions Attached

The mechanism comes with a fixed set of conditions in 200.201(b). Read them as contract terms, because that is how they behave.

One: the price is negotiated, not proposed and accepted. The agency uses cost principles and available pricing data as a guide, but the budget is settled in advance and does not float. If your assumptions are wrong, the number does not move later.

Two: payment is structured, and you should structure it. The regulation lists three permitted forms — several partial payments tied to a named milestone or triggering event, a unit price basis with defined units agreed in advance, or a single payment at completion. All three must be written into the award. A single payment at the end is legal and it is also a cash flow problem; negotiate milestones.

Three: no cost sharing. A fixed amount award “must not be used in programs that require cost sharing.” If the program mandates a match, this structure is off the table entirely. That one line disqualifies a large share of otherwise promising programs, so check it first.

Four: completion certification, with reduction for shortfall. At the end you certify in writing that the project was completed as agreed, or you identify what was not completed. Where activities were not carried out — including on unit-price awards — the award is reduced by the value of the missing work. The upside and downside are symmetric: deliver under budget and keep the difference, under-deliver and repay proportionally.

Five: records still matter. The absence of financial reporting does not suspend the record retention requirements at 200.334 through 200.338, and it does not exempt you from producing records during an audit. Organizations that read “no financial reporting” as “no bookkeeping” learn otherwise at single-audit time.

Six: narrowed prior approvals. Only a subset of the 200.308(f) prior-approval triggers apply, plus the subaward rules in 200.333. Fewer permission slips, but not none.

What You Give Up in Exchange

The tradeoff is scope rigidity. Cost reimbursement is forgiving about how a project evolves — budgets get rebudgeted, timelines slip, and the agency generally cares that the money was spent on allowable things. A fixed price cares about whether the thing got built. If your enrollment target was 400 participants and you reach 340, the reduction clause is not discretionary.

You also lose the ability to absorb a surprise. A cost-reimbursement award can often accommodate a 20% cost overrun through rebudgeting or a supplement. A fixed price cannot; the overrun is yours. That is why the regulation conditions this structure on the existence of “accurate cost, historical, or unit pricing data.” The mechanism is designed for work you have done before at a price you can defend.

For organizations without a strong operational track record, the honest read is that cost reimbursement is the safer instrument. For a nonprofit running a repeatable program at known unit economics, the fixed price is close to free money in administrative terms. The decision turns on cost certainty, not on organizational size.

OMB Has Proposed Ending It

On May 29, 2026, OMB and 41 other agencies published the Regulation for Federal Financial Assistance, the largest revision to 2 CFR Part 200 since 2013. Among more than 300 proposed changes, the rewrite of 200.201 and 200.333 would prohibit fixed amount awards and subawards unless authorized by statute. OMB’s stated rationale is the same feature recipients value: because there is no routine cost monitoring and no financial reporting, the agency argues the structure gives it too little visibility into how funds are spent.

The response was unusual in scale. Roll Call reported 496,769 comments filed during the 45-day window that closed July 13, with an AI analysis of the first 51,000 published comments finding 94% in opposition. The National Council of Nonprofits urged OMB to withdraw the proposal in its entirety, and practitioner commentary has argued specifically that removing the fixed-price option pushes small community organizations out of direct competition and into subrecipient status under larger primes.

Nothing is final. OMB targeted an October 1, 2026 effective date, appropriations text under discussion in early August would push implementation later, and a comment record of that size normally slows a final rule. The practical posture is not panic — it is timing. The rule as drafted would apply to new awards and new incremental funding issued after the effective date, which means awards negotiated now, and their existing terms, sit on the earlier side of the line. Keep watching program notices in the OpenGrants grant database for language that signals a milestone-priced structure.

How to Ask, While the Option Is Open

Program officers rarely volunteer this structure. Asking is a short, specific conversation, and the answer is usually determined before you call.

Start by screening out the disqualifiers: does the program require cost sharing, and does the notice of funding opportunity or agency policy address this award type at all? If cost sharing is required, stop. If the program is silent, the next question is whether your scope has measurable goals and whether you can produce pricing evidence — prior invoices, published rates, per-participant costs from a previous cycle. That evidence is what turns the request from a preference into a justified budget.

Then propose the payment schedule yourself rather than waiting to be handed one. Name three or four milestones with a dollar amount attached to each, tied to events the agency can verify without an audit: cohort enrolled, curriculum delivered, final report accepted. Pass-through entities are the more approachable target here, since a prime already holding a cost-reimbursement award can often issue a fixed amount subaward within its own threshold. If you are building a pipeline of small business and community funding targets, flag which ones have a pass-through layer — that is where the mechanism survives longest.

Frequently Asked Questions

Do I really keep money I do not spend?

Yes, if the scope was completed as agreed. 2 CFR 200.201(b)(4) states that when the required activities were carried out under the award’s terms, the recipient is entitled to any unexpended funds. The condition is full performance, not partial. If some activities were not completed, the award is reduced by an amount reflecting the missing work, and that applies to unit-price awards as well as milestone-based ones.

Does no financial reporting mean no audit exposure?

No. The regulation suspends routine cost monitoring and financial reporting, but record retention under 200.334 through 200.338 still applies, and records must be available for review during an audit. The award also counts toward federal expenditures for single-audit purposes. Keep the books you would otherwise keep; you simply are not submitting them on a schedule.

How large can a fixed amount subaward be?

It depends on the agency. NIH recognizes a $500,000 prior-approval threshold for fixed amount subawards unless a specific funding notice says otherwise. NSF permits them only up to the simplified acquisition threshold and describes them as uncommon. Always check the prime award’s terms and the agency’s current policy notice rather than assuming a government-wide number.

If OMB finalizes the rule, do my current awards convert?

Not automatically. The proposal would apply to new awards and new incremental funding issued on or after the effective date. Existing awards are not permanently insulated, though: agencies can incorporate new terms at modification or renewal, so a multi-year award typically meets new rules at its next amendment rather than immediately.

Bottom Line

Treat the fixed amount award as a priced contract you happen to win competitively, not as a lighter version of a grant. The three questions that decide whether it fits are whether the program forbids cost sharing, whether your scope is measurable, and whether you can defend the price with real historical data. If all three answers land the right way, this is the most favorable payment structure in federal financial assistance, and asking for it costs one email.

The specific action worth taking this quarter: pull your active pass-through relationships and identify any subaward being negotiated now that could be written on milestones instead of cost reimbursement. That window is defined by a proposed rule, not by your fiscal year, and the terms in an award signed today are the terms you carry into the next amendment. If you want help structuring the scope, the pricing evidence, and the milestone schedule so the request holds up, OpenGrants’ managed grant writing team builds those budgets for a living.
