Calculate paid work hours from a start time and end time with optional break minutes and overnight shift handling.

Calculate shift hours, paid hours, and break-adjusted work time

Use this working hours calculator when you need to total a shift, subtract unpaid break time, and see how many paid hours remain. It works well for payroll prep, shift planning, timesheets, staffing schedules, and quick work hour checks.

A working hours calculator helps you calculate paid hours from a start time and end time while also showing the gross shift span before breaks are removed.

End time is on the next day

If you leave this off and the end time is earlier than the start time, the calculator treats it as an overnight shift automatically.

Find paid hours from a start time and end time

This tool calculates paid working hours from a shift start time and end time, then subtracts break minutes from the gross shift span. It shows the paid hours first and also breaks out the gross shift length, paid minutes, and decimal hours.

A working hours calculator is useful for payroll prep, timesheet hours, staffing schedules, shift planning, and quick checks before you log or approve hours worked. It is especially helpful when you need payroll hours or shift hours after breaks instead of the full shift span.

Break minutes are subtracted from the full shift span after the calculator measures the total time between the start and end time. If the end time is earlier than the start time, the tool can treat it as an overnight shift automatically or with the explicit next-day option.

How do you calculate work hours from a start time and end time?

Enter the shift start time and end time, then add break minutes if part of the span should be unpaid. The calculator measures the full shift span first and subtracts the break to show the paid work hours.

Does this subtract break time from the result?

Yes. Enter break minutes and the tool subtracts them from the gross shift span before showing the paid hours.

Can this working hours calculator handle overnight shifts?

Yes. If the end time is earlier than the start time, the calculator can treat the shift as overnight automatically. You can also turn on the next-day option directly.

What happens if break minutes are longer than the full shift?

The tool shows a clear validation error instead of returning a misleading negative or zero work-hour result.
