Freelance Non Billable Hours Calculator
Estimate how many unpaid working hours you spend on admin, marketing, meetings and other non-billable tasks each week or month.
Overview
The Freelance Non Billable Hours Calculator helps you estimate how much time you spend each week on unpaid work such as admin, marketing, meetings and professional development. By comparing those hours with your billable time and working capacity, you can better understand your utilization and the hidden cost of running your freelance business.
How it works
The calculator adds together your unpaid work categories to find your total non-billable hours each week. It then compares that total with your billable hours to calculate the share of your worked time that is not invoiced. It also converts weekly unpaid hours into a monthly estimate and multiplies those hours by your average hourly rate to show the approximate revenue value of time spent on non-billable tasks.

Frequently asked questions
What counts as non-billable hours for freelancers?
Non-billable hours usually include admin, proposals, marketing, unpaid calls, business development, bookkeeping, learning and other work you cannot invoice directly to a client.

Tracking non-billable time helps you understand your real workload, price projects more accurately and avoid overestimating how many client hours you can sell.
What is a good billable utilization rate?
It depends on your business model, but many freelancers cannot bill 100% of their time because running the business also requires unpaid work.
Can this calculator help with pricing?
Yes, it can highlight how much working time is unpaid, which may help you review your rates or project pricing approach.
