Frequently asked questions

What is a wrap rate in government contracting?

A wrap rate (fully burdened labor rate) is your direct labor rate marked up by your indirect rates — fringe, overhead, and G&A — plus fee or profit. It's what you actually bill the government per labor hour. The wrap rate calculator shows the build-up step by step. See the indirect rates guide for the underlying concepts.

Are these calculators free to use?

Yes — completely free, no sign-up, and they run entirely in your browser, so no data is sent anywhere. You're also welcome to link to or embed them at no cost.

How do I know if my business is small for a NAICS code?

Compare your average annual receipts (or employee count) to the SBA size standard for that NAICS code. The size standard calculator checks several common codes; for the authoritative current figure, confirm against the SBA table of size standards. More detail: NAICS codes & size standards.
