Utilization & Capacity

Billable Utilization Rate

Agency glossary · Updated July 2026

Definition

Billable utilization rate is the share of a person’s available working hours that goes to billable client work. It shows how much of the labour capacity an agency pays for actually earns revenue, and it is the main lever between headcount and profit.

FormulaBillable hours / available hours x 100

Why it matters

Every point of utilization you recover turns already-paid capacity into billable output without new hires. Parakeeto notes a roughly 10-point gain on the same team can add about six figures of annual profit.

Benchmark

Delivery staff typically run about 65 to 85% on an annual basis; whole-agency utilization, counting non-delivery roles, is usually 50 to 60%. Sustained readings above roughly 80 to 85% signal understaffing or burnout, not a win.

Common mistake: dividing by all paid hours instead of true available hours after holidays and PTO, which makes the number look artificially low.

Frequently asked questions
