About this calculator

Utilization rate measures what share of an employee’s or contractor’s total available working hours are actually billed to clients — billable hours divided by total available hours — and is one of the core efficiency metrics tracked at agencies, consulting firms, and professional services businesses.

A target utilization rate in the 70–85% range is typical, since some time inevitably goes to administrative work, internal meetings, and business development that can’t be billed to a client. This calculator divides billable hours by available hours to compute the utilization rate as a percentage.
