What Is a Firm-Fixed Price Contract?
A firm-fixed price (FFP) contract establishes a price for a defined scope of work when the contract is awarded. That price is not subject to adjustment based on the contractor’s cost experience during contract performance unless a formal contract modification changes the terms.
Instead of reimbursing actual costs, the government purchases the agreed work for the negotiated contract amount.
That structure places cost risk on the contractor.
If the work costs less than expected, the contractor keeps the additional profit. If costs exceed expectations, the contractor absorbs the difference.
Because of that risk, accounting for FFP contracts requires clear cost visibility and disciplined financial management during contract performance.
Why Cost Tracking Matters on Fixed-Price Work
The misconception that fixed price means minimal accounting.
Some contractors assume that fixed-price contracts require less accounting oversight because the contract price is already established.
In practice, strong cost tracking becomes even more important.
If project costs exceed expectations, the contractor absorbs the difference. Profit margins shrink, and in some cases, the contractor must fund the overrun.
Contractors still need to manage costs on an FFP contract the same way they would on any other contract type. Without reliable cost tracking, it’s difficult to see how the project is performing financially while the work is underway.
Profitability management and future pricing decisions.
Cost tracking also helps contractors understand how their projects actually perform.
Lower-than-expected costs increase profitability. Higher costs reduce margins. Without reliable cost data, contractors can’t clearly see where those changes occur.
That information also improves future pricing decisions. Historical cost performance helps contractors estimate more accurately when bidding on new government contracts.
Essential Accounting Principles for FFP Contracts
GAAP Revenue Recognition (ASC 606)
Revenue recognition for government contracts must follow generally accepted accounting principles.
Under ASC 606, revenue is recognized when or as a contractor satisfies its performance obligations under the contract. In some cases, revenue is recognized over time as work progresses. In other situations, revenue may be recognized at a specific point in time when deliverables are transferred to the customer.
The correct treatment depends on how the performance obligations in the contract are defined and how control of the work is transferred.
Reliable cost tracking supports this process. Project cost data helps determine progress toward completion of the work and supports consistent financial reporting throughout the life of the contract.
FAR Part 31 Cost Principles that Still Apply
Firm-fixed price contracts generally are not reimbursed based on actual costs. The government pays the negotiated contract price rather than the contractor’s incurred costs.
However, FAR Part 31 cost principles can still play a role in pricing and negotiating fixed-price contracts, subcontracts, or contract modifications when cost analysis is required.
Applying consistent cost classification and cost discipline also helps contractors maintain reliable financial reporting and pricing practices across government work.
Revenue Recognition Methods
Several revenue recognition approaches may apply when accounting for FFP contracts. The appropriate method depends on the contract structure and the nature of the work being performed.
Cost-to-Cost Percentage of Completion
The cost-to-cost method is commonly used for longer-term government contracts.
This method compares actual costs incurred to estimated total contract costs to determine the percentage of work completed.
Example:
Total contract value: $1,000,000
Estimated total costs: $800,000
Costs incurred to date: $400,000
Percent complete = 400,000 ÷ 800,000 = 50%
Revenue recognized to date = 50% × $1,000,000 = $500,000
Direct cost tracking is essential for this method. Actual costs incurred are compared to estimated total costs to determine the percent complete and calculate earned revenue.
Milestone-Based Recognition
Some firm-fixed price contracts structure performance around defined milestones.
Milestones may represent development phases, technical deliverables, or other measurable stages of work. Revenue may be recognized when those milestones are achieved, and the associated performance obligations are satisfied.
Units Delivered Method
Contracts involving manufacturing or delivery of discrete units may recognize revenue as units are delivered and accepted under the contract terms.
Selecting the Right Method
The appropriate revenue recognition method depends on the contract structure, the type of work being performed, and the performance obligations defined in the contract.
Contractors should apply a consistent policy that aligns with accounting standards and internal financial reporting practices.
Cost Tracking and Classification
Direct vs. Indirect Costs
Accounting for FFP contracts requires clear cost classification.
Direct costs are expenses that can be traced directly to a specific contract. These often include labor hours, materials, and subcontractor costs associated with the project.
Indirect costs support overall business operations and cannot be tied to a single contract. Examples include administrative salaries, facility costs, and other shared operational expenses.
Accounting systems should clearly separate these cost categories to ensure accurate evaluation of project performance.
Job Costing and Overhead Allocation
Job costing tracks expenses at the contract level and provides visibility into how costs accumulate during performance.
Indirect costs are allocated using defined allocation methods so contractors can understand the full financial picture of each project.
Reliable job costing enables contractors to monitor profitability throughout contract performance rather than discovering issues after the project is complete.
Managing Profitability and EAC
Understanding Estimate at Completion
Estimate at Completion (EAC) represents the projected total cost of a contract at completion.
It includes costs incurred to date plus the estimated costs required to complete the remaining work.
Example:
Costs incurred to date: $300,000
Estimated remaining costs: $450,000
EAC = $750,000 projected total cost
EAC helps contractors evaluate whether the project is performing within the original cost expectations and what the final profit margin may look like.
Monthly Monitoring and Early Warning Signs
EAC should be reviewed regularly throughout contract performance.
Many contractors compare the original projected margin with the margin implied by the current EAC. If EAC rises above the original budget, projected profit declines.
Regular monitoring helps identify cost issues early so project teams can investigate the causes and respond appropriately.
Contract Modifications and Changes
Firm-fixed price contracts remain fixed unless the government issues a formal modification.
When scope, schedule, or contract requirements change, the government may issue a modification that adjusts the contract price or performance requirements. Those changes affect more than the contract document. They also affect financial reporting.
When a modification is issued, contractors should update project budgets and revise their Estimate at Completion (EAC). Changes in scope or pricing can alter the projected total cost of the contract and the expected profit margin.
Revenue recognition should also be reviewed. If a modification changes the scope of work or the contract value, contractors may need to adjust how revenue is recognized going forward to reflect the revised contract terms.
Maintaining clear documentation of contract modifications helps ensure financial reporting remains accurate and aligned with the updated contract structure.
Critical Internal Controls
- Accounting systems that separate direct and indirect costs
- Timekeeping systems that track labor by project and cost category
- Project reporting that calculates revenue and margins at the contract level
- Regular monitoring of contract costs against budgets
- Routine updates to the Estimate at Completion calculations
- Consistent revenue recognition policies applied across contracts
These controls create traceability between accounting records, project reporting, and financial statements.
Common Mistakes to Avoid
- Failing to Track Contract Costs
Some contractors assume that because the contract price is fixed, detailed cost tracking isn’t necessary. Without cost visibility, it becomes difficult to monitor profitability or identify cost issues during contract performance. - Not Calculating EAC Regularly
Estimate at Completion provides a forward-looking view of contract performance. Contractors who don’t update EAC regularly may miss early warning signs that project costs are exceeding expectations. - Recognizing Revenue Based on Billing
Revenue recognition should follow accounting standards rather than the timing of invoices. Recognizing revenue upon invoice submission can lead to inaccurate financial reporting.

Accounting for FFP Contracts Requires More Than Setting the Contract Price
Firm-fixed-price contracts seem straightforward because the contract value is known at the start. The risk sits behind that number. Cost tracking, job costing, EAC monitoring, and revenue recognition all determine whether the contract performs as expected.
When those systems are built correctly, financial visibility improves, and margin surprises become less likely.
FAQ: FFP Contract Accounting
Do cost accounting standards apply to firm-fixed price contracts?
Cost Accounting Standards (CAS) applicability depends on the contract’s characteristics and whether the award meets any CAS exemptions. Some fixed-price contracts are exempt from CAS, while others may be subject to modified or full CAS coverage.
Contractors should review CAS applicability based on the contract award and the applicable regulatory thresholds.
What is the main cost risk in a fixed-price contract?
The primary risk is that actual costs exceed expectations. Since the contract price is fixed, the contractor absorbs the difference, and profit margins decline.
Do I need to track costs if the price is already fixed?
Yes. Cost tracking helps contractors monitor profitability, support revenue recognition, and evaluate project performance throughout the contract lifecycle.
How often should I update my EAC?
Estimate at Completion should be reviewed regularly during contract performance. Many contractors update EAC monthly to monitor projected costs and expected profit margins.
