Freelance Workload Calculator
Estimate how many client hours, billable days, and projects you can realistically take on based on your schedule, admin time, and target utilization.
Overview
The Freelance Workload Calculator helps you estimate how much client work you can realistically take on each week and month. Enter your working days, hours per day, non-billable time, utilization target, and average project size to get a practical view of your capacity.
How it works
The calculator starts with your total weekly working hours by multiplying working days by hours per day. It then removes your non-billable time to estimate the hours available for client work. After that, it applies your target utilization so you are not aiming to book every available hour. Finally, it converts that recommended billable time into billable days and estimated project volume based on your average hours per project.

With a 5-day week, 8 hours per day, 25% non-billable time, and an 85% utilization target, the recommended billable workload is about 25.5 hours per week. That equals roughly 2.1 average projects per week, or about 9.2 projects per month.
Frequently asked questions
What does this calculator estimate?
It estimates a realistic weekly and monthly billable workload based on your schedule, non-billable time, utilization target, and average project size.
What is non-billable time?
Non-billable time includes tasks you cannot directly charge for, such as admin, marketing, sales calls, invoicing, email, and internal planning.
What does utilization mean for freelancers?
Utilization is the share of your available billable capacity that you aim to book with paid client work. Many freelancers leave a buffer instead of targeting 100%.
Why should I avoid booking 100% of my available time?
A full schedule leaves little room for revisions, client communication, delays, or new opportunities. A buffer can make workloads more sustainable.
Can I use this calculator for retainer and project work?
Yes. You can use an average hours-per-project estimate for project work, or treat a retainer as a recurring project with a typical monthly time requirement.
How accurate is the projects per month result?
It is a planning estimate based on your average project size. Actual capacity may differ if some projects are much larger, smaller, or more complex than usual.
