Understanding Indirect Rate Structures for Government Contracts

Why Indirect Rates Matter in GovCon

If you are bidding on cost-reimbursement contracts or any work subject to DCAA audit, your indirect rate structure is the foundation of your pricing. Indirect rates — fringe benefits, overhead, and general & administrative (G&A) expenses — typically represent 50% to 150% of your direct labor costs. Getting them wrong means either leaving money on the table or facing a DCAA audit finding that could jeopardize your contracts.

Unlike commercial pricing where you set margins based on market rates, government contract pricing follows a cost-accounting framework defined by FAR Part 31 (Allowable Costs) and the Cost Accounting Standards (CAS). Every dollar you charge must be allocable, allowable, and reasonable. Understanding these principles is not optional — it is a compliance requirement.

The Four Key Indirect Rate Pools

Fringe Benefits Rate: This covers your employee benefits costs — health insurance, retirement contributions, paid leave, payroll taxes (FICA, FUTA, SUTA), workers compensation, and other benefits. A typical fringe rate for a GovCon firm ranges from 30% to 45% of direct labor. The base is usually total direct labor dollars. If your direct labor rate is $50/hour and your fringe rate is 35%, the fringe cost adds $17.50/hour.

Overhead Rate: Overhead captures the indirect costs of running your operational departments — project management tools, IT infrastructure for project teams, facility costs allocated to operations, indirect labor for supervisors and technical leads who support multiple projects. Overhead rates in GovCon typically range from 40% to 100% of direct labor plus fringe. The key is proper allocation — overhead costs must benefit your direct contract work.

General & Administrative (G&A) Rate: G&A expenses are company-wide costs that benefit all business activities — executive salaries, corporate rent, legal fees, accounting, business development, proposal costs, and administrative staff. G&A is typically applied as a percentage of total cost input (direct labor + fringe + overhead + other direct costs). Rates commonly range from 10% to 25%.

Fee/Profit: On cost-type contracts, your profit is negotiated as a fixed fee, usually ranging from 6% to 10% of estimated costs. On FFP contracts, your profit is built into the price but still needs to be reasonable. DCAA will examine whether your proposed profit aligns with government guidelines.

Building a Compliant Rate Structure

Start with a forward-pricing rate proposal. Project your costs for the next fiscal year: total direct labor by category, expected fringe costs, overhead expenses, and G&A costs. Divide each indirect pool by its allocation base to get your provisional rates. These provisional rates are what you use in proposals until DCAA audits your actual incurred costs and establishes final rates.

Maintain a chart of accounts that clearly separates direct costs, fringe, overhead, and G&A. Use a timekeeping system that captures labor by project and cost element. The most common DCAA audit finding for small contractors is inadequate timekeeping — make sure every employee records their time daily, distinguishing between direct project work, overhead, G&A, and unallowable activities.

Common Pitfalls

Unallowable costs are the biggest risk area. FAR 31.205 lists specific cost categories that cannot be charged to government contracts — entertainment, alcoholic beverages, lobbying, certain legal fees, and fines/penalties among them. If unallowable costs are mixed into your indirect pools, your rates are inflated and DCAA will require adjustments.

Another common mistake is inconsistent cost treatment. If you charge a cost as direct on one contract and indirect on another, you violate CAS 402 (Consistency in Allocating Costs). Pick a method and apply it uniformly across all contracts.
