The price proposal — sometimes called the cost volume or business volume — is the part of your bid where the government checks whether your numbers are real. The technical volume says what you will do; the price proposal proves you can do it at the price you quoted. Learning how to build a price proposal that survives evaluation is a skill in itself, and it is one that separates bidders who win from bidders who get thrown out on a technicality or a realism finding.
What Goes in the Price Volume
Most solicitations tell you exactly what the price volume must contain, in Section L. Typically it includes a summary price schedule — the total price by contract line item (CLIN) and by period of performance — a detailed cost breakdown by labour category, hours, and rate, a breakdown of other direct costs and subcontractor costs, your indirect rates and how they were calculated, and a basis of estimate (BOE) explaining how you arrived at every number. Some RFPs also require a separate fee proposal, a small-business subcontracting plan cost summary, or a statement of your accounting system status.
The first rule is to follow the RFP’s structure exactly. If it asks for prices by CLIN, price by CLIN. If it provides a pricing template, use it — do not substitute your own format. Evaluators compare offers side by side, and a price volume in a different format slows them down and invites errors. Run the price volume through our proposal compliance checklist before submission, just as you would the technical volume: missing a required price element is a deficiency, not a detail.
The Basis of Estimate: Your Most Important Document
The basis of estimate is the narrative that explains your price. For each major cost element, it says what the cost is, how you calculated it, and what evidence supports it. “Program manager, 1,920 hours at $68.50 per hour, based on current salary plus fringe and overhead at our provisional rates” is a basis of estimate. “Management: $150,000” is not.
A strong BOE does three things. First, it makes your price auditable: an evaluator or a cost analyst can follow your arithmetic from the assumption to the total. Second, it makes your price defensible: when the government asks why your price is higher or lower than the competition, the BOE is your answer. Third, it protects you during negotiations: if the government asks you to reduce your price, the BOE tells you exactly which assumption you would have to change, and whether you can afford to change it. Write the BOE as you build the price, not after — reconstructing assumptions from memory is how errors creep in.
Building the Cost Breakdown
Build the price from the bottom up, in this order. Start with the labour plan: every labour category, the number of people, the hours per person per period, and the rate for each category. Your hours must match the staffing plan in the technical and management volumes exactly — an evaluator who finds 1,920 hours in the price and 1,760 in the technical volume will question both. Next, add other direct costs: travel (with trips, people, and per-diem rates), materials, equipment, software licences, and any other cost that belongs to this contract alone. Then add subcontractor costs, with each sub’s quote attached or summarised, including their rates and the scope they cover.
Then apply your indirect rates — fringe, overhead, and G&A — in the right order and on the right base, as explained in our guide to indirect rates. Then add profit or fee. Then check the total against your research: past award data and the incumbent’s pricing, where you can find it. If your total is far above or below the range you expected, stop and find out why before you submit — the cause is usually a scope misunderstanding, and it is cheaper to fix it now than to lose the award or the contract later.
Price Realism and Consistency Checks
On many competitions the government performs a price realism analysis: it checks whether your price is high enough to actually perform the work. A price that is far below the independent government estimate, or far below the other offerors, can be judged unrealistic — even if it is the lowest price. The most common cause of an unrealistically low price is an underestimated labour plan: too few hours, too junior a mix, or rates that do not cover your real costs. Your BOE is your defence against a realism finding, so make it thorough: show your hours, show your rates, show your sources.
Consistency is the other check. The price volume, the technical volume, and the management volume must tell the same story. The hours must match. The staffing must match. The subcontractors named in the price must be the subcontractors named in the technical approach. The period of performance must match. Before submission, have someone who did not build the price cross-check the three volumes line by line. The mistakes this catches — a transposed number, a missing CLIN, a rate applied to the wrong base — are the mistakes that lose awards.
Common Price Proposal Mistakes
Several mistakes recur in price proposals. The first is the missing element: a required schedule, a required rate disclosure, or a required subcontractor quote left out. The second is the arithmetic error: a spreadsheet formula that sums the wrong range, or a total that does not match the sum of its parts. The third is the inconsistent labour mix: the price uses junior rates while the technical volume promises senior staff. The fourth is the undocumented assumption: a big number with no BOE behind it, which the evaluator cannot verify and therefore cannot trust. The fifth is the price that does not match the proposal: the technical volume promises 24/7 coverage and the price funds one shift. And the sixth is submitting the price in the wrong place — some solicitations require the price in a separate volume or a separate envelope, and a price that appears in the technical volume can be grounds for rejection.
Guard against all six with a simple routine: build the price from the technical volume, not separately from it; write the BOE as you go; reconcile every number twice; and submit the volumes exactly as the RFP instructs. A price proposal is not a formality. It is the part of your bid that proves the rest of it is real.

Price Proposal: Check Every Number Before You Submit
A strong price proposal is built twice: once from the technical volume, and once from the ground up. Build it from the technical volume first, so every labour hour and material cost traces to a task the evaluators can see. Then rebuild it from your own rates and past costs, and compare the two totals. If the price proposal numbers do not match, the gap is where the realism finding will land — fix the gap before the agency finds it.
Before you submit, run the volume through our proposal compliance checklist and our guide on how to price a government contract bid, and check how agencies analyse proposals in FAR Part 15. A price proposal that survives that final review is one you can defend in front of any evaluator.
