Indirect Cost (Indirect Cost)
An indirect cost is an expense that cannot be specifically identified with or directly charged to a single final cost objective, such as a government contract, task order, or project. These costs support multiple activities and are allocated across contracts using an approved methodology.
What Is Indirect Cost?
An Indirect Cost is any expense that cannot be specifically identified with or directly charged to a single final cost objective, such as a particular government contract, task order, or project. Instead, indirect costs benefit multiple contracts or the business as a whole, and they are allocated across cost objectives through a defensible allocation method.
Typical indirect cost categories include fringe benefits (employer-paid taxes, health insurance, retirement), overhead (facilities, depreciation, indirect labor like supervision), and general and administrative or G&A expenses (executive compensation, accounting, legal, marketing). Each category is accumulated in a separate cost pool, divided by an allocation base, and expressed as an indirect rate that is applied to direct cost incurred on each contract.
Key Characteristics
Indirect costs have several distinguishing characteristics. They cannot be specifically traced to a single cost objective; that is what distinguishes them from direct costs.
They are accumulated in indirect cost pools (typically fringe, overhead, and G&A) and allocated through an allocation base (often direct labor dollars for overhead, and total cost input for G&A). The allocation rates are expressed as percentages: an overhead rate of 75 percent means 75 cents of overhead is allocated for every dollar of direct labor.
Indirect rates are evaluated annually through provisional billing rates and finalized through an Incurred Cost Submission (ICS) that the Defense Contract Audit Agency audits on cost-type contracts. Indirect cost allocation must comply with Cost Accounting Standards when applicable, and with the cost principles in FAR Part 31.
How It Works in Government Contracting
Indirect cost treatment affects federal contractors at three points. First, at proposal time, the contractor proposes provisional indirect rates that will apply during the contract's performance, supported by historical actuals and forward pricing rate proposals.
The contracting officer's price analyst reviews the rates and may negotiate a forward pricing rate agreement. Second, during billing, the contractor applies provisional rates to direct costs on each invoice, with periodic adjustments as actuals develop.
Third, at year-end, the contractor submits an ICS comparing actual indirect rates to provisional rates and DCAA audits the submission, leading to a final settlement that adjusts past billings. Errors at any of these stages can result in DCAA disallowance, DCAA audit findings, or False Claims Act exposure if the rate misrepresentation was knowing. Our piece on proposal accuracy and compliance covers how compliance-aware platforms reduce these risks.
Real-World Example
A federal services contractor with $20 million in direct labor proposes an overhead rate of 75 percent and a G&A rate of 12 percent. During performance, the firm bills the agency at these provisional rates against $5 million of direct labor on a specific task order, generating $3.75 million of overhead and $1.05 million of G&A allocation.
At year-end, the firm submits its ICS showing actual rates of 72 percent overhead and 11.5 percent G&A. DCAA audits the submission, agrees with the actuals, and the contracting officer adjusts prior-year billings downward by the difference.
The firm refunds approximately $185,000 in overbilled indirect costs. Tracking the actuals in a dedicated job cost code structure that mirrors the indirect rate pools is how the firm reconciled the variance cleanly.
Regulatory Framework
Indirect cost treatment is governed by FAR Part 31 (Contract Cost Principles and Procedures), particularly FAR 31.203, which establishes the rules for indirect cost accumulation and allocation. Cost Accounting Standards in 48 CFR Chapter 99 apply to contractors above CAS thresholds and add precise rules on cost pool definition and allocation.
For DoD contractors, DFARS adds further audit and submission requirements. DCAA reviews indirect rates under DCAM Chapter 6, and final settlement procedures are governed by FAR 42.7.
Contractors with cost-type federal contracts above $250,000 must annually submit an Incurred Cost Submission within six months of fiscal year-end under FAR 52.216-7.
Why It Matters for Contractors
Indirect cost treatment is the single biggest determinant of whether a federal contractor's cost proposals are credible and whether its accounting system passes DCAA audit. Wrong rates undermine proposal competitiveness: too low and the firm wins work but loses money; too high and the firm prices itself out.
Poor allocation methods produce audit findings that can disqualify the firm from cost-type work for years. Past performance ratings reflect how cleanly the firm handles cost reporting, and weak indirect cost discipline is one of the most common drivers of unfavorable CPARS narratives.
Strategic contractors maintain documented cost accounting policies, review pool composition annually, run rolling forecasts of indirect rates, and integrate indirect rate movement into year-to-date contract performance monitoring. Our piece on ROI of an AI proposal platform shows how good indirect cost discipline flows through to higher win rates.
Common Misconceptions
All overhead is indirect cost.
Not quite. Overhead is one category of indirect cost; G&A is another, and fringe is often a third. Each is accumulated and allocated separately. Lumping them together produces inaccurate rates and audit findings.
Indirect cost rates are fixed once the year starts.
They are not. Provisional rates apply during the year and final rates are negotiated after year-end through the ICS process. Actuals can vary meaningfully from provisional, requiring billing adjustments.
Only cost-reimbursement contracts care about indirect costs.
They do not. Firm-fixed-price contracts include indirect costs in the proposed price; getting the indirect rate wrong on an FFP proposal still costs the firm directly through margin erosion, even though billing does not adjust afterward.
Frequently Asked Questions
What is the difference between direct cost and indirect cost?
Direct costs can be specifically identified with a single contract or project (direct labor of a contract-billable employee, materials consumed on a specific contract). Indirect costs benefit multiple cost objectives or the business as a whole and are allocated through indirect rates. Misclassification is a common DCAA audit finding.
What is a forward pricing rate agreement (FPRA)?
An FPRA is a written agreement between a contractor and a contracting officer establishing certain indirect rates and labor rates for use in proposals over a defined period. FPRAs reduce repeated negotiation of the same rates on each proposal and provide certainty for both sides. They are governed by FAR 42.17.
How are indirect rates audited?
DCAA audits incurred cost submissions on a risk-based sampling basis, focusing on cost pool composition, allocation base, and rate calculation. Issues include unallowable costs in the pool, improper allocation base, and misclassification between cost categories. Our compliance automation playbook walks through how teams prepare for these audits.
What costs are unallowable in indirect cost pools?
FAR 31.205 lists unallowable costs that must be excluded from indirect pools, including entertainment, advertising for general firm promotion, lobbying, certain legal costs, and many others. Including unallowable costs in pools is a common DCAA finding and can trigger penalty assessments.
When must a contractor submit an Incurred Cost Submission?
For contractors with cost-reimbursement contracts above $250,000, the ICS is due within six months of fiscal year-end under FAR 52.216-7. The submission documents actual indirect rates and direct cost incurrence by contract. Late or inadequate submissions trigger contract administration consequences and can be a finding under DCAA's adequate accounting system review.
