Kavaro's Free Tools

Free utilisation calculator

Work out resource utilisation and billable utilisation for an agency or professional services team. Add people, enter hours, and see who is under, on target, or over a 70–85% planning range for delivery roles. Nothing is sent to a server.

Team hours

Available hours are the denominator (working time after leave). Assigned / planned hours are booked load. Billable hours and charge rate are optional.

How it works?

1

Add people and hours

Enter available hours for the period, then assigned or planned hours. Add billable hours and a charge rate if you want billable utilisation and optional revenue.

2

Calculate in the browser

The calculator divides assigned and billable hours by available hours for each person and for the team. Hours are not sent to Kavaro or an API.

3

Read the flags

Under 70%, 70–85% on target, and over 85% for delivery roles. Use the flags as a planning check, then read the full formula in the utilisation rate guide.

FAQ

How do I calculate utilisation rate?

Resource utilisation = assigned or planned hours ÷ available hours. Billable utilisation = billable hours ÷ available hours. Available hours should already subtract leave, public holidays and contracted non-working days. See the full worked example in how to calculate utilisation rate.

What is the difference between resource utilisation and billable utilisation?

Resource utilisation is how full someone’s calendar is (assigned ÷ available). Billable utilisation — sometimes called chargeability — is how much of their available time is client-billable work (billable ÷ available). Someone can be 100% utilised on internal work and still have low billable utilisation.

What is a good utilisation rate for an agency?

For delivery roles, many professional services firms plan in a 70–85% range so there is room for leave, sickness, sales support and the work that never makes the timesheet. 100% is not a healthy target. These are planning ranges, not Kavaro settings.

Does this calculator import hours into Kavaro?

No. Hours stay in your browser. There is no import, sync, or upload. If you want utilisation from live bookings and timesheets, that is a separate product workflow in Kavaro.

Is utilisation the same as utilization?

Yes. Utilisation is the UK spelling; utilization is the US spelling. The formula is the same.
