Work Hours Calculator
Add up the hours on a time card — with breaks, overnight shifts and overtime — and work out gross pay at your hourly rate.
Result
Enter your shifts to total the hours.
How to use this calculator
- Enter each shift’s start and end time (9:00, 5:30 pm and 17:30 all work) and its unpaid break.
- Add an hourly rate and overtime rules to see pay.
Formula
Worked time = end − start − break. If the end is earlier than the start, the shift ends the next day. Hours above the weekly threshold are paid at the overtime multiplier.
Worked example
A standard week
Five shifts of 9:00–17:30 with 30-minute breaks total 40 hours; at 20 an hour that is 800. Six 8-hour shifts are 48 hours: 40 regular + 8 overtime at 1.5× = 1,040.
Assumptions and limitations
- Everything runs in your browser; nothing you enter is uploaded or stored.
- Overtime is calculated on total hours; some places also have daily overtime rules.
