How It Works

total = (hours + minutes / 60) × rate × number of days or projects

Frequently Asked Questions

What is the "number of days or projects" field for?

Use it to multiply a single billable session across several identical days or projects — for example, if you bill the same 2 hours a day for 5 days, enter 5. Leave it at 1 for a single calculation.

Can I bill in a currency other than USD?

Yes. The calculator does not restrict the rate to US dollars — enter your rate in whatever currency you invoice in and treat the total the same way. The display simply uses a dollar-style format.

How do I enter partial hours, like 45 minutes?

Enter 0 in the hours field and 45 in the minutes field, or combine them, such as 2 hours and 45 minutes for 2 hours 45 minutes of billable time.

Does this round billable time to the nearest increment?

No, this calculator uses your exact minutes. Some firms round billable time to the nearest 6 or 15 minutes — apply that rounding to your minutes before entering them here if your billing policy requires it.
