Employee utilization rate measures the percentage of an employee’s available working hours spent on billable or otherwise productive, value-generating work, versus non-billable, administrative or idle time, the inverse of what sits on the bench.

Formula and typical benchmarks

Utilization Rate = (Billable/Productive Hours ÷ Total Available Hours) × 100

An employee with 160 available working hours in a month, after subtracting weekly offs and holidays, who logs 120 billable hours against client projects, has a utilization rate of (120 ÷ 160) × 100 = 75%. Typical targets vary by industry: IT consulting commonly runs around the low-to-mid 70s percent, management consulting somewhat lower, contact centers considerably higher, often 80 to 90%, and agencies somewhat lower again. Management and leadership roles, and anyone with a wide span of control, are expected to run lower utilization by design, since strategic, non-billable work is genuinely part of the job rather than a shortfall.

Frequently asked questions

Is 100% utilization the goal?

No, that’s usually unrealistic and unhealthy, some non-billable time for training, admin and rest is expected and built into most targets.

Does utilization rate apply outside services and IT?

It’s most commonly used in services, consulting, staffing and IT, where billable hours map directly to revenue, less commonly tracked in other business models.

How does utilization relate to bench cost?

Low utilization across a team generally means a larger bench and higher bench cost, the two metrics move together.
