Behind every winning government proposal lies a carefully developed federal proposal cost structure. This structure not only reflects the resources needed to perform the work but also signals to evaluators that your company understands cost realism, pricing compliance, and delivery feasibility. A well-organized cost structure improves the credibility of your offer and directly influences the likelihood of award.
Cost is one of the primary factors in federal procurement decisions. Even when the technical score is strong, a poorly structured or unrealistic cost volume can lead to rejection. For contractors of all sizes, building a sound cost structure is essential to remaining competitive and compliant.
What Is a Federal Proposal Cost Structure?
A federal proposal cost structure is the framework used to estimate, organize, and present the full costs associated with contract performance. It breaks down total costs into categories such as direct labor, indirect rates, subcontractor expenses, other direct costs (ODCs), and fee or profit. This framework must align with the solicitation’s cost or pricing requirements and justify how the proposed price was developed.
The cost structure tells the government how much you’re charging, why, and how you built those figures. It also must demonstrate that your company can complete the work as proposed within the stated price.
Key Components of a Federal Proposal Cost Structure
Understanding the major cost components is the first step toward building a defensible and compliant structure. Most cost volumes include the following:
1. Direct Labor
This includes salaries or hourly wages paid to employees working directly on the contract. The estimate must consider labor categories, hours, rates, and locations, and should align with the technical solution’s staffing plan.
2. Indirect Costs
Indirect costs include fringe, overhead, general and administrative (G&A), and other burdened rates that apply across multiple contracts. These rates should be well documented and, ideally, approved by DCAA or based on historical data.
3. Subcontractor Costs
Costs associated with any subcontractors performing part of the work. These should include labor, indirects, and any applicable fee. The cost structure should also explain how subcontractor roles support the overall execution strategy.
4. Other Direct Costs (ODCs)
ODCs include items like travel, materials, equipment, or licenses required to complete the work. These costs should be clearly broken out and supported with assumptions.
5. Escalation
Multi-year proposals often include escalation for labor and indirect rates. The assumptions behind these escalations should be reasonable and clearly stated.
6. Fee or Profit
The proposed profit margin or fee structure must reflect the level of risk, contract type, and competitive positioning. Fee structures that appear excessive or misaligned with the contract type may raise evaluation concerns.
Aligning the Cost Structure with the Technical Approach

Your federal proposal cost structure must be tightly linked to your technical and management volumes. Evaluators will look for consistency between the solution and the budget. For example:
The staffing plan in the technical volume should match the labor hours in the cost volume
Key personnel named in the proposal should be reflected in labor categories and pricing
Proposed schedules must align with the duration and phasing in the cost structure
Subcontractor roles described in the narrative should be mirrored in their cost contributions
Discrepancies between volumes often result in lower scores or realism concerns during evaluation.
Tailoring Cost Structures to Contract Types
Each contract type requires a different emphasis in the cost structure:
Fixed-Price Contracts: Focus on bottom-line costs and price justification. Labor effort assumptions must be defensible even though the price is not reimbursed.
Cost-Reimbursable Contracts: Emphasize transparency and realism. All cost elements must be fully explained, and rates must be current and supportable.
Time & Materials Contracts: Highlight labor categories and hourly rates. Ensure clarity on what is billable and what is covered under indirects or overhead.
IDIQ Contracts: Establish ceiling rates or pricing matrices that allow for flexibility across future task orders. Include assumptions for scope variability.
Each format has unique documentation and justification requirements that shape how the cost structure is presented.
Common Mistakes in Cost Structure Development
Avoid these common pitfalls when building a federal proposal cost structure:
Using outdated or unverified indirect rates
Failing to match the cost structure with the technical approach
Over- or underestimating labor categories and level of effort
Providing insufficient backup for ODCs or subcontractor pricing
Applying inconsistent escalation assumptions across cost elements
Even small inconsistencies can create doubt in the evaluator’s mind and jeopardize your proposal.
Tips for Strong Cost Volume Presentation
A strong federal proposal cost structure is not only accurate—it’s easy to follow. Use these tips:
Use clear tables that break down costs by CLIN, labor category, and year
Include a narrative that explains assumptions and calculations
Label cost elements consistently across spreadsheets and text
Highlight any cost efficiencies or pricing advantages in your approach
Ensure all formulas and totals are functioning properly
Formatting and readability play a significant role in how your pricing is perceived.
Tools and Resources to Support Cost Structure Development
Successful cost development often requires internal tools or outside support. Use the following resources to strengthen your proposal:
Internal historical pricing databases
DCAA-compliant accounting systems and templates
Public award data from SAM.gov and FPDS
Labor benchmarking data for specific NAICS codes
Excel-based cost models that automate burden calculations
For contractors that need additional help, cost proposal consultants can guide the process and ensure full alignment with solicitation requirements.
