Hours Worked Calculator

Calculate hours worked from start, end and breaks.

Start time (h (0–24))

End time (h (0–24))

Break

Hours worked 8

Formula: hours = end − start − break/60

Step-by-step with your numbers:

1. Values used:

2. Start time = 9 h (0–24)

3. End time = 17.5 h (0–24)

4. Break = 30

6. Hours worked = 8

Did we solve your problem today?

Work out a shift length after subtracting unpaid breaks.

The math behind it

hours = end time − start time − break (in hours). Enter times as decimals, e.g. 5:30 PM = 17.5.

9.0 to 17.5 with 30 min break → 8 hours.

Overnight shift?

Add 24 to the end time if it crosses midnight (e.g. 1 AM = 25).
