Accountants Billable Hours Calculator
Estimate annual billable hours and potential fee income from your working schedule, utilization rate and hourly billing rate.
Overview
This Accountants Billable Hours Calculator estimates how many hours you may be able to charge to clients each year and the potential fee income from those hours. Enter your normal schedule, expected billable utilization and average hourly billing rate to create a practical capacity target.
How it works
The calculator first estimates your scheduled annual working hours by multiplying hours per day, working days per week and working weeks per year. It then applies your billable utilization rate to account for administration, business development, training, internal meetings and other non-chargeable time. Finally, it multiplies estimated billable hours by your average hourly billing rate to estimate potential fee income.

Frequently asked questions
What are billable hours for an accountant?
Billable hours are the hours spent on work that can be charged to a client, such as preparing accounts, tax work, bookkeeping, advisory work or client meetings.
What is a good billable utilization rate for an accountant?
A suitable rate depends on the role, service mix and support available. The rate should leave enough time for administration, client acquisition, training, quality control and internal work.
Should I include annual leave in working weeks per year?
No. Enter the weeks you expect to work after allowing for annual leave, public holidays, sickness, training and other planned time away.
Why is billable utilization lower than my working time?
Not every working hour is chargeable. Time spent on administration, marketing, invoicing, professional development, internal meetings and practice management is usually non-billable.
Does estimated billable revenue equal profit?
No. Billable revenue is potential fee income before expenses. Profit also depends on wages, software, premises, insurance, taxes, financing and other business costs.
Can I use this calculator for fixed-fee accounting work?
Yes, if you use an effective hourly rate. Divide the expected fixed fee by the expected delivery hours to estimate the rate realised for that type of work.
