How to Write a Cost/Price Volume for Government Proposals

Cost Proposals vs Price Proposals

The distinction between a cost proposal and a price proposal is fundamental. A cost proposal is required for cost-reimbursement contracts (cost-plus types like CPFF, CPIF, CPAF). It breaks down every element of cost — labor, materials, travel, subcontracts, indirect rates, and fee — so the government can evaluate whether your estimated costs are realistic and reasonable. Cost proposals are subject to DCAA audit and must comply with FAR Part 15 and FAR Part 31.

A price proposal is submitted for firm-fixed-price or fixed-price contracts. The government evaluates the total price for reasonableness but generally does not audit individual cost elements. However, for competitively negotiated procurements above the simplified acquisition threshold, the government may still request cost or pricing data per FAR 15.403.

Regardless of contract type, your pricing must be internally consistent. If your technical volume proposes 10 software engineers for 12 months, your cost volume must show the corresponding labor hours and rates. Inconsistencies between volumes are a common reason for evaluation downgrade.

Direct Labor Costs and Rates

Direct labor is typically the largest cost element. For each labor category, you must establish a billing rate that includes the employee's base salary (or hourly wage) and may include escalation factors for multi-year contracts. Labor categories should align with the RFP's required categories or, if the RFP allows your own categories, with your company's established rate structure.

Develop a labor hours estimate for each task area in your WBS. Map hours to specific labor categories and show the basis of estimate (BOE) for how you derived the hours. Common estimation methods include analogous estimation (based on similar past contracts), parametric estimation (using industry metrics like lines of code per developer-month), and bottom-up estimation (detailed task-level estimates rolled up).

If you are proposing named individuals as key personnel, their actual salaries form the basis for those labor rates. For non-key positions, use composite rates or average rates for the labor category. Document your rate methodology — the government will want to understand why your Senior Systems Engineer is billed at $85/hour versus $120/hour.

For multi-year contracts, include annual escalation factors (typically 2-4% per year) to account for salary increases. Apply escalation consistently and document the basis, such as Bureau of Labor Statistics wage growth data or your company's historical merit increase percentages.

Indirect Rate Application

Indirect rates — fringe benefits, overhead, and general and administrative (G&A) — are applied on top of direct costs. For cost-type contracts, these rates must be established through your DCAA-adequate accounting system and are proposed as provisional rates, subject to annual audit and true-up.

Fringe benefits include employer-paid taxes (FICA, FUTA, SUTA), health insurance, retirement contributions, PTO accruals, and other employee benefits. Fringe is applied as a percentage of direct labor dollars. Typical rates range from 25% to 45% depending on your benefits package.

Overhead covers indirect costs associated with performing work: facilities, equipment, utilities, indirect labor (supervisors, admin staff not directly charging), and supplies. Overhead is typically applied to direct labor plus fringe. Companies with multiple cost centers may have different overhead pools for on-site, off-site, and OCONUS work.

G&A covers company-wide expenses: executive management, finance, HR, legal, marketing, and business development. G&A is typically applied to total cost input (all direct costs plus overhead). G&A rates for government contractors commonly range from 8% to 25%. If your rates are higher than industry norms, be prepared to explain why during negotiations.

Other Direct Costs (ODCs)

Other direct costs include materials, equipment, travel, software licenses, training, and any other costs that can be directly attributed to the contract but are not labor. ODCs must be itemized and justified. Simply including a lump-sum "ODC pool" without breakout will draw scrutiny from evaluators and auditors.

For travel, estimate the number of trips, duration, destination, and per diem rates using the GSA per diem schedule. For materials and equipment, provide catalog pricing, vendor quotes, or historical purchase data. For software licenses, specify the product, number of licenses, and annual renewal costs.

The handling of ODCs in your rate structure matters. Some companies apply G&A to ODCs; others exclude them. Your disclosure statement (if CAS-covered) dictates the treatment. Ensure your proposed treatment is consistent with your established accounting practices.

Subcontractor Costs

Subcontractor costs are presented separately from your direct costs. Each subcontractor should provide their own cost proposal, which you include as an appendix to your cost volume. The government evaluates subcontractor costs for reasonableness just as it evaluates your prime costs.

When integrating subcontractor pricing, clearly show the subcontractor's total proposed cost by period of performance. If you plan to apply a subcontractor handling fee (sometimes called a "wrap rate" or "pass-through rate"), ensure it is reasonable. DCAA scrutinizes subcontract handling fees that exceed what is justified by the actual management and administrative effort the prime performs.

For contracts subject to small business subcontracting plans, ensure your subcontractor mix supports your subcontracting goals. The cost volume should be consistent with the subcontracting commitments made in your subcontracting plan.

Fee and Profit Calculation

For cost-type contracts, fee (profit) is a separately negotiated element. Statutory limits cap fees at 10% of estimated cost for R&D contracts and 15% for other types. The government uses a weighted guidelines analysis (FAR 15.404-4) to evaluate proposed fees based on factors including contractor effort, cost risk, investment, and performance.

For CPFF contracts, the fee is a fixed dollar amount that does not change regardless of actual costs. For CPIF contracts, the fee adjusts based on cost performance relative to the target cost, within minimum and maximum fee boundaries. Your fee proposal should be competitive but sufficient to justify the risk and investment you are making.

For FFP contracts, profit is embedded in the total price. The government may request a cost buildup showing your estimated costs and profit margin even for FFP procurements, particularly when certified cost or pricing data is required. In these cases, profit percentages typically range from 7% to 15% depending on the contract risk, complexity, and competitive environment.

Cost Realism vs Cost Reasonableness

These two evaluation standards are different and have significant implications for your pricing strategy. Understanding which standard applies to your procurement is critical.

Cost Reasonableness

Cost reasonableness asks: "Is the proposed price fair and reasonable given market conditions?" This standard applies to FFP contracts. The government compares your price against competing offers, historical pricing, independent government estimates, and published price lists. A price that is significantly higher than competitors may be deemed unreasonable.

Cost Realism

Cost realism asks: "Are the proposed costs realistic for the work described in the technical approach?" This standard applies to cost-type contracts (and sometimes to FFP contracts when evaluating technical risk). The government may adjust your proposed costs upward if they determine your estimate is unrealistically low. This means that "buying in" with an artificially low cost proposal can backfire — the government evaluates your probable cost, not your proposed cost.

For cost realism evaluations, ensure your labor hours, rates, and indirect rates are well-documented and consistent with your technical approach. If you propose fewer hours than the government estimates are reasonable, be prepared to justify your efficiency with concrete evidence from past performance. The most dangerous position is proposing low costs that the government adjusts upward, making you both expensive (adjusted probable cost) and risky (you underestimated the effort).
