Billable Time Calculator

Free billable time calculator: convert hours and minutes, round up to billing increments and calculate the fee.

How the billable time calculator works

Enter hours, minutes, your rate and an optional rounding increment to see billable time and the amount to invoice.

Billable minutes = total minutes rounded up to the increment. Amount = billable hours × hourly rate.

Example: 2h 10m rounded up to 15-minute blocks is 2h 15m (2.25 hours); at 80 per hour the fee is 180.00.

Many professionals bill in 6, 15 or 30-minute increments to keep invoices simple. State your increment in your agreement.
