Proposal Pricing: Building a Defensible Cost Volume

The cost volume is where winnable technical proposals often lose. A defensible cost volume is not a price; it is a constructed, documented estimate that survives the government's cost realism analysis and supports the technical approach you proposed. Building it from the ground up — rather than reverse-engineering a price to win — is what makes it defensible.

Build from the ground up

A ground-up cost estimate starts with the technical approach: the labor categories and hours required to deliver each element of the statement of work. Each labor category carries a direct rate; the hours times the rates produce direct labor. Add indirect rates — overhead, general and administrative, and fee or profit — consistent with your incurred cost structure and your forward pricing rate agreement if you have one. Add escalation for the period of performance. The sum is the cost estimate; the documentation is the build-up.

Labor categories must match the technical approach

The labor categories and hours in the cost volume must match the technical approach in the technical volume. A cost volume that assumes a senior architect where the technical volume describes a mid-level team is internally inconsistent — and cost realism analysis will catch it. The two volumes are one proposal; the pricing must reflect the approach.

Indirect rates and cost realism

The government evaluates cost realism on cost-type contracts and some fixed-price contracts. The evaluator assesses whether your proposed costs are realistic for the work, and may adjust your evaluated cost upward if your rates or hours are unrealistically low. Indirect rates inconsistent with your incurred cost submission or your forward pricing rate agreement invite adjustment. The defensible cost volume uses rates you can support with your accounting records and your FPRA.

Risk and contingency

A defensible cost volume addresses risk explicitly. Contingency for scope uncertainty, escalation risk, and performance risk should be documented and reasonable — not buried in inflated hours. A cost volume with hidden contingency is a cost volume that fails realism and erodes trust. A cost volume with explicit, documented risk is a cost volume that survives review.

Documentation is the deliverable

The cost volume's defensibility is in its documentation as much as its numbers. The buildup, the basis of estimate for each labor category, the indirect rate reconciliation, and the escalation assumptions are the record an evaluator — and an audit — will examine. The price is the output; the documentation is the deliverable. GovCon Architect supports the cost volume through the capture-to-proposal link, so the labor and approach in the technical volume flow into the cost build-up rather than being reconstructed in isolation.
