Two firms can pay an engineer the exact same salary and still submit wildly different prices for the same work — because the number that turns a salary into a billable rate, the wrap rate, can differ enormously. Built from your indirect cost rates, the wrap rate multiplies every labor hour you bid, which makes it one of the most consequential figures in federal pricing. This guide explains the indirect pools that feed it, how the wrap rate is calculated, why it decides competitiveness, and how to manage it without crossing into unrealistic pricing.
Direct costs — the salary of the person doing the work, or the materials consumed on a job — are only part of the picture. Every business also incurs indirect costs that support the work but cannot be charged to a single contract: benefits, facilities, management, accounting, IT. Federal pricing requires you to recover those costs through indirect rates layered onto your direct labor. How efficiently you do that determines your wrap rate, and the wrap rate multiplies every hour you bid. On a labor-heavy contract, indirect rates often decide the outcome more than the salaries themselves.
Most contractors organize indirect costs into three pools, each with a cost numerator and an allocation base:
Each rate is simply the pool cost divided by its base. A clean pool structure is also central to a DCAA-adequate accounting system — see our guide on DCAA compliance.
The wrap rate is built up layer by layer, with each rate compounding on the running total. Start with direct labor at $1.00. Add fringe as a percentage of labor; add overhead as a percentage of labor plus fringe; then apply G&A to the new total. For example, fringe at 30%, overhead at 25%, and G&A at 12% compound to a wrap of roughly 1.82 before fee. Apply your fee on top to reach the fully loaded billable rate. So an employee with a $50 direct hourly cost might bill at about $96 once burden and a typical fee are applied. The precise math depends on your allocation bases, which is why two firms with similar salaries can price very differently.
Because the wrap rate multiplies every direct labor hour, even a small difference compounds across a large contract. A firm at a 1.6 wrap can bid the same staff at materially lower fully loaded rates than a competitor at 2.0, while still recovering costs and earning fee. On price-sensitive services work — much of the federal services market — controlling indirect costs is often the single biggest lever on your price competitiveness. This is why growing firms watch their wrap rate as closely as their revenue: it directly governs how much work they can win.
During the year you bill using provisional (billing) rates — estimates, often negotiated with your cognizant agency. After year-end you calculate final rates from actual costs and report them in your incurred cost proposal under FAR 52.216-7. The government then settles the difference, recovering money if your provisional rates ran high or paying more if they ran low. Setting realistic provisional rates protects your cash flow and keeps you out of trouble at audit. The same realism applies in proposals: cost realism analysis on cost-type work will catch rates that are too good to be true. For the full pricing picture, see our guide on pricing a federal proposal.
You can lower your wrap rate legitimately by trimming indirect costs, by growing your direct labor base so fixed indirect costs spread across more hours, or by restructuring pools so costs allocate more efficiently. What you cannot do is simply understate rates to win, because incurred cost audits and cost realism analysis will surface unrealistic numbers — and the contract type you are bidding shapes how much scrutiny your rates receive. See how type drives pricing in our guide on federal contract types. Some firms deliberately bid a thinner forward-pricing rate to win an anchor contract or enter a new market, accepting lower margin as a strategic investment.
