Indirect rate calculator

Compute fringe, overhead, and G&A from pool and base.

Enter the pool and base for each indirect cost category. The calculator returns the rate you would propose to the cognizant contracting agency under FAR Part 31. Standard small-business pool structure: fringe on direct labor, overhead on fringed labor, G&A on total cost input.

Want the loaded billing rate too?

The Wrap Rate Calculator takes these indirect rates and applies them to a direct labor base to produce a fully loaded T&M rate.

Defensible rates need monthly tracking, not just year-end math.

Every contractor that fails an incurred cost proposal review failed it for the same reason: provisional rates drifted from actuals and nobody noticed until year-end. The FieldLedger Indirect Rate Engine tracks pools and bases monthly so the variance is visible in time to fix.
