How to calculate utilisation

  • Available hours = capacity − leave (holidays, sickness, bank holidays).
  • Utilisation rate = billable hours ÷ available hours × 100.
  • Team utilisation = total billable hours ÷ total available hours, not an average of each person’s rate.

The tool runs entirely in your browser. Nothing you type is sent to Angelwood or saved on a server.

Using the calculator

  1. Pick a period, such as a month, and use the same period for everyone.
  2. Enter each person’s billable hours, contracted capacity and leave.
  3. Set a target. Targets differ by role: client-facing delivery roles are usually expected to bill more than managers.

Worked example

A designer has 160 hours of capacity, 8 hours of leave and 118 billable hours: 118 ÷ 152 = 77.6%. Across the calculator’s default three-person team, 274 billable hours out of 416 available is 65.9%, short of a 75% target by 38 billable hours.

GOOD QUESTIONS

Questions people ask.

Talk to us
What is a good utilisation rate?

It depends on role and business model. Delivery roles are usually expected to bill more than leadership or account management. Set targets per role rather than one number for everyone.

Should leave count as available time?

No. Removing holidays and sickness from capacity gives a fairer rate and stops people looking under-utilised in months with leave.

Is utilisation the same as productivity?

No. Utilisation measures how much time is billable, not the value of the work. Pair it with project profitability to see whether billable time is earning enough.
