Agency utilization rate calculator

Plug in your agency's billable and available hours for a single week. You'll see your utilization rate and where it sits relative to the healthy band for agencies your size.

Your inputs

Include anyone delivering client work, not just full-time billable roles.
Typical baseline: 40 hrs minus PTO, all-hands, and required non-client time.
Hours on client work that is invoiced or allocated to retainer scope.
Pitches, internal projects, training. For sanity-checking your math.

Healthy utilization benchmark

Utilization band What it signals
< 55% (Under-deployed)Pipeline too soft, or too much time on non-billable activity. Margin will suffer.
55–64% (Below healthy)Sustainable but signaling weak pipeline or heavy internal investment. OK short-term.
65–75% (Healthy)Enough slack for QA, business development, recovery. Most sustainable band for service agencies.
76–84% (Hot)Margin-maximizing but fragile. One missed project or sick week and delivery slips.
85%+ (Over-utilized)Delivery failure is a matter of when, not if. QA is being skipped. Burnout is accumulating.

Why utilization alone doesn't tell the story

Utilization is a leading indicator of delivery health but not a sufficient one. An agency at 72% utilization with no structured QA and a six-month pipeline hole is in worse shape than one at 82% with a clean operating rhythm and a healthy pipeline. Use utilization as one reading, not the only one.

Two metrics to watch alongside utilization:

Frequently asked questions

What is a healthy agency utilization rate?

65–75% across the whole team is healthy for service agencies of 6–25 people. Senior and specialist roles typically run 55–65%.

How do you calculate agency utilization rate?

(billable hours ÷ total available hours) × 100. Available = 40 hrs minus PTO, sick, and required all-hands.

Should we target 100% utilization?

No. 100% eliminates slack for QA, BD, learning, and recovery. Agencies that chase it under-invest in quality.

What is the difference between utilization and billability?

Utilization measures time spent on client work. Billability measures how much of that work is actually invoiced.
