Agency Utilization Rate Calculator: Know Your Numbers

Most agency founders I talk to can tell me their revenue. Very few can tell me their utilization rate — and almost none can tell me what a 5-point improvement in utilization would mean for their bottom line.

That gap is expensive. Use the calculator below to find out exactly where you stand.

What the numbers mean

Utilization rate is simply the percentage of available hours your team actually bills to clients:

Utilization rate = (billable hours ÷ available hours) × 100

If your team has 40 hours available per person per week and logs 28 billable hours, your utilization rate is 70%.

For a deeper look at what these benchmarks mean and how they vary by agency type and size, see our agency utilization rate benchmark guide.

The three zones

Below 65% — leaving money on the table. At this level, a meaningful chunk of your payroll isn't generating revenue. Common causes: too much non-billable internal work, poor project scheduling, scope creep eating into capacity, or simply not enough client work in the pipeline. The fix usually isn't "work more hours" — it's better scheduling and tighter project scoping.

65–75% — the healthy range. This is where profitable agencies operate. You have enough buffer for business development, internal projects, and unexpected overruns without burning anyone out. If you're here, focus shifts to rate optimization and margin — not utilization.

Above 75% — watch carefully. High utilization feels good until it doesn't. Teams consistently above 80% start making mistakes, missing deadlines, and eventually burning out. If you're in this zone, the answer is either shedding low-margin work or hiring before you lose someone.

What actually moves utilization

The levers that move your number, in rough order of impact:

1. Scheduling discipline. Most utilization problems are scheduling problems. If you don't have visibility into who has capacity and when, work gets distributed unevenly — some people are buried while others have slack. A capacity planning view (even a simple one) closes this gap fast.

2. Non-billable time. Internal meetings, admin, pitches, and sales all draw from the same available-hours pool. Track where non-billable time is actually going before assuming the problem is pipeline.

3. Write-offs and overruns. Hours worked but not billed drag down your effective utilization. If your team is technically "billing" 70% but 10% of those hours get written off, your realized rate is closer to 63%. Tighten scope, improve estimation, or adjust how you price.

4. Rate, not hours. Once you're in the healthy band, the highest-leverage move is usually rate — not squeezing more hours out of the team. A 10% rate increase on the same utilization does more for margin than pushing from 70% to 75%.
