Freelance Utilisation Rate Calculator
Calculate your freelance utilisation rate based on available working hours, billable hours and time off to understand how effectively your time generates revenue.
Overview
A freelance utilisation rate calculator helps you see how much of your available working time turns into paid client work. By entering your working days, hours per day, planned time off, billable hours and hourly rate, you can estimate your utilisation percentage, annual billable hours and potential billable revenue.
How it works
The calculator first estimates your available working hours for the year by multiplying working days per week by hours per day and then by your working weeks after time off. It then estimates annual billable hours from your average billable hours per week over the same working weeks. Your utilisation rate is the percentage of available hours that are billable. It also estimates non-billable hours and annual billable revenue using your average hourly rate.

If you work 5 days a week for 8 hours a day, take 4 weeks off, and average 25 billable hours per week at 75 per hour, your utilisation rate is about 62.5%, with 1200 billable hours out of 1920 available hours and estimated billable revenue of 90000.
Frequently asked questions
What does a freelance utilisation rate mean?
It shows the percentage of your available working time that is spent on billable client work.
What is a good utilisation rate for freelancers?
It varies by industry and business model, but many freelancers need room for admin, sales, marketing and breaks, so 100% billable time is rarely realistic.
Should I include admin time as billable?
Only include hours you actually charge to clients as billable. Admin and internal business tasks should usually be treated as non-billable.
Why is my utilisation rate lower than expected?
Freelancers often spend significant time on proposals, client communication, invoicing, marketing, learning and gaps between projects.
Can I use this calculator for monthly planning?
Yes. You can use your weekly averages to estimate annual utilisation, then divide the yearly figures into monthly targets if needed.
Does this calculator show profit?
No. It estimates billable revenue, not profit. Expenses, taxes, software, subcontractors and unpaid invoices are not included.
