Work Hours Calculator

Enter your start time, end time and any unpaid break, and this calculator works out the total hours for your shift — including overnight shifts that cross midnight. Add an hourly rate to also see an estimated gross pay for the shift.

How it works

Enter your clock-in and clock-out time and this calculator subtracts your unpaid break to give you the total hours worked. If your end time is earlier than your start time, the shift is treated as crossing midnight — for example, starting at 22:00 and finishing at 06:00 — and a full day is added before the break is subtracted.

Tip

Enter an hourly rate to also see your estimated gross pay for the shift, before taxes and deductions.
