Project Profitability Calculator for Freelancers
The invoice total is not your profit. Add expenses and unpaid hours to see the real margin and hourly rate on a project.

Why invoice total is not profit
Revenue is what you billed. Profit is what remains after you pay for project costs. If you don't account for expenses and time spent outside billable work, your effective rate drops fast.
Example: $5,000 project
With $5,000 revenue, $500 expenses, 80 billable hours, and 20 unpaid hours, net profit is $4,500.00 (90.0% margin) at a real hourly rate of $45.00 per hour across 100 total hours.
How this differs from Project Profit Check
This calculator breaks down a single project: revenue minus expenses gives net profit and margin, and divides net profit by total hours (billable + unpaid) to show your real hourly rate. The quick Project Profit Check takes a slightly different angle on fee, hours, expenses, and taxes to estimate your real rate.
