About this calculator
Find the duration of a shift, including overnight shifts and breaks.
Useful for day, evening and overnight shifts.
Formula
Shift length = finish − start − unpaid break. If finish is earlier than start, the calculator treats it as the next day.
Example
22:00 to 06:00 with a 30-minute break = 7.50 paid hours.
Accuracy
NUMTX shows the assumptions next to the calculation so you can replace defaults with values that match your situation. For measurements, supplier rates, fees, interest, tax or regulated work, confirm important figures with the appropriate official or professional source.
