Frequently asked questions

How does the Billable Hours Calculator work?

It takes Hours worked per week, Billable percentage, Hourly rate and Working weeks per year and derives Billable hours per week, Weekly revenue and Annual revenue from them. The calculation is live as you type, so the result updates on every change.

Which values does the calculator ask for?

4 values: Hours worked per week, Billable percentage, Hourly rate and Working weeks per year. Nothing else is required — no account, no file upload.

What does a typical calculation look like?

With Hours worked per week = 40, Billable percentage = 60, Hourly rate = 75 and Working weeks per year = 46, the calculator returns Billable hours per week = 24, Weekly revenue = $1,800.00 and Annual revenue = $82,800.00. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

How much does the result change with different inputs?

It moves a lot. Using Hours worked per week = 80, Billable percentage = 66, Hourly rate = 82.5 and Working weeks per year = 92 instead, Billable hours per week goes from 24 to 52.8 — which is why it is worth testing a few scenarios rather than trusting a single figure.

What does it give for smaller values?

Scaled down to Hours worked per week = 20, Billable percentage = 54, Hourly rate = 67.5 and Working weeks per year = 23, Billable hours per week comes out at 10.8. The relationship is worth checking at both ends before you rely on a single result.

When would I actually use this?

Budgeting a hire properly, converting between working-time bases, and checking what leave, overtime or a departure actually costs.

What is the most common mistake?

Budgeting the salary as the cost of the hire. Employer contributions, paid leave, equipment and the recruitment itself typically add 20% to 60% on top, depending on the country.

What is the difference between the Billable Hours Calculator and the Work hours calculator?

This one returns Billable hours per week and Weekly revenue; the Work hours calculator returns Hours worked and Total minutes. That is the whole difference — open the one whose figure you need.

Is there a tool for the next step?

Employee cost calculator is the closest one after this: Estimate the total cost of an employee from gross salary and employer charges.

What else is worth having open alongside it?

Overtime pay calculator and Labor cost percentage calculator — they come up in the same task often enough to be worth a second tab.
