Accountants Utilisation Rate Calculator
Calculate the percentage of available accountant time spent on billable client work and compare it with a utilisation target.
Overview
This accountants utilisation rate calculator estimates the proportion of available working time spent on billable client work. Enter billable hours, scheduled hours, leave or unavailable time, and a target rate to assess capacity and performance for a chosen period.
How it works
The calculator first deducts leave and unavailable time from scheduled hours to find available capacity. It then divides billable hours by available hours and expresses the result as a percentage. It also multiplies available hours by your target rate to show the billable hours needed to meet that target.

Frequently asked questions
What is an accountant utilisation rate?
It is the percentage of available working time that is spent on billable client work. It is commonly used to monitor capacity and time efficiency.
How is utilisation calculated?
Utilisation equals billable hours divided by available hours, multiplied by 100. Available hours are scheduled hours less leave and other unavailable time.
Should leave be included in utilisation calculations?
Leave is usually deducted from scheduled hours so that the calculation reflects the time genuinely available for client work.
What is a good utilisation rate for accountants?
A suitable target depends on role, seniority, client demands, administrative duties, and firm policies. Use a benchmark that fits the work being measured.
Why can utilisation be above 100%?
It can exceed 100% if recorded billable hours are greater than entered available hours, perhaps because of overtime, timing differences, or incomplete leave records.
Can this calculator be used for an accounting team?
Yes. Enter combined billable, scheduled, and unavailable hours for all team members over the same reporting period.
