About Utilisation Rate (Agency) Calculator

Utilisation is billable hours over available hours and drives agency profitability more than rate does. Because available hours already exclude leave, a target much above 80% leaves no room for training or business development.

Formula

Utilisation

Utilisation = billable hours / available hours

Frequently Asked Questions

What utilisation is healthy?

Around 70-80% for delivery staff. Above that, quality and retention usually suffer.

Should sold-but-unworked hours count?

No. Utilisation measures work done, not work sold — conflating them hides delivery problems.
