About this calculator
Calculate hours worked from start time, finish time and unpaid breaks.
Use this for a single shift. Enter the actual clock-in and clock-out times and subtract only unpaid breaks.
Formula
Hours worked = finish − start − unpaid breaks. Overnight shifts are handled automatically.
Example
09:00 to 17:30 with a 30-minute unpaid break = 8.00 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.
