Hours Calculator
Free hours calculator. Work out the total hours and minutes between a start and end time, subtract unpaid breaks, and get your worked hours for a timesheet.
Calculate hours worked
Enter your start and end times and the calculator works out the total time between them, then subtracts any unpaid break to give your worked hours — shown both as hours and minutes and as a decimal for payroll. It even handles overnight shifts where the end time is earlier than the start.
Why decimal hours?
Payroll systems usually want hours as a decimal, not hours-and-minutes. For example, 8 hours 30 minutes is 8.5 hours. Add your hourly rate and the tool also estimates your gross pay for the shift.
Frequently asked questions
How do I calculate hours worked?⌄
Enter your start and end times; the calculator finds the difference, subtracts any unpaid break, and shows the total in hours and minutes plus a decimal.
How do I convert minutes to decimal hours?⌄
Divide the minutes by 60. So 8 hours 30 minutes is 8.5 decimal hours — the format most payroll systems use.
Does it handle overnight shifts?⌄
Yes. If the end time is earlier than the start time, the calculator assumes the shift runs past midnight and adds 24 hours.
