The wrap rate for labor categories on a federal services contract is driven by direct labor costs, indirect costs, and profit. Direct labor includes the employee's base salary or hourly wage. Indirect costs are where it gets fuzzy for many, but they are crucial. These include fringe benefits like health insurance, paid time off, and retirement contributions, plus payroll taxes such as FICA and unemployment. Beyond that, you have overhead costs directly tied to supporting labor, like office space, utilities, IT infrastructure, and administrative support. General and Administrative (G&A) expenses, which are company-wide, also get factored in, covering things like executive salaries, legal fees, and marketing. Finally, the profit margin your company expects to make on the contract is added. For federal contracts, the Federal Acquisition Regulation (FAR) Part 31 details cost principles, which guide what costs are allowable and how they should be allocated, so you need to understand that. State and local government contracts follow their own procurement codes, which can vary wildly. I lost money on my first few contracts because I didn't account for every indirect cost, so don't make my mistake.
