The utilization rate formula

Utilization rate is billable hours divided by available hours, expressed as a percentage. If a consultant has 40 available hours in a week and bills 30, that’s 75% utilization. Simple to calculate — the nuance is in which hours you count as “available” and which as “billable,” because that choice changes the number.

Billable vs. resource utilization

There are two common versions. Billable utilization measures hours billed against total available hours — the revenue view. Resource (or productive) utilization measures all productive hours, billable or not, against available hours — the workload view. Reporting one when you mean the other is a common source of confusion, so define which you’re using.

What’s a healthy utilization rate?

Targets vary by role and firm, but most services businesses aim for billable utilization in the 70–80% range for delivery staff. Too low and you’re carrying idle capacity; too high and you’re risking burnout and leaving no room for the non-billable work — training, pre-sales, internal projects — that a healthy firm still needs.

Why accuracy depends on time capture

A utilization rate is only as good as the time data behind it. If hours are estimated from memory, the number is fiction. Accurate, in-the-flow time capture is what makes utilization a metric you can manage rather than guess at. Cloud Coach captures time and reports utilization natively on Salesforce.
