How it is calculated
Formula: Utilization rate = billable hours / available hours x 100
Available hours are the hours a person can realistically work after holidays, PTO, sick time, and unavoidable admin. Utilization is the share of those hours that goes to billable client work, so it shows how much of the capacity you pay for actually earns money.
Delivery and production staff typically run about 65 to 85% on an annual basis. Whole-agency utilization, counting non-delivery roles, is usually lower at 50 to 60%. Sustained readings above roughly 80 to 85% signal understaffing or burnout, not efficiency.

Delivery and production staff typically target about 65 to 85% billable utilization on an annual basis, or 75 to 90% in a strong week. Whole-agency utilization, including non-delivery roles, usually runs 50 to 60%. Above 80 to 85% sustained signals burnout, not efficiency.
Utilization rate is billable hours divided by available hours, times 100. Available hours are the schedulable hours left after holidays, PTO, and admin. If someone bills 28 of 40 available hours, utilization is 70%.
Common causes are too much non-billable admin, gaps between projects, over-hiring ahead of demand, or simply not recording all billable time. Compare delivery staff separately from account and management roles, which naturally bill less.
