Calculate hours worked, including an unpaid break
Work hours are the time from clock-in to clock-out minus any unpaid break. For example, 9:00 AM to 5:30 PM is 8 hours 30 minutes; subtracting a 30-minute unpaid break leaves 8 hours, or 8.0 decimal hours.
If clock-out is earlier than clock-in, this calculator treats the shift as ending the next day. A 10:00 PM to 6:00 AM shift is therefore 8 hours before breaks.
Need a span longer than one overnight shift? Use the hours between two times calculator. Need to add several completed shifts? Use the hours calculator.
How do I calculate work hours with a lunch break?
Subtract the unpaid break from the gross time between clock-in and clock-out. A 9:00 AM to 5:00 PM shift with a 30-minute unpaid lunch is 7 hours 30 minutes, or 7.5 decimal hours.
Does this calculate overtime pay?
No. It calculates elapsed work time only. Overtime, pay, rounding and break rules depend on the policy or law that applies to you.
