Formula
Worked time = end − start − unpaid breakIf end < start (overnight): worked time = end + 24 h − start − breakDecimal hours = hours + minutes ÷ 60 (e.g. 7:45 = 7.75)Overtime = total weekly hours − weekly limit (if positive)Pay = regular hours × rate + overtime hours × rate × overtime multiplier
How it is calculated
- Pick your country in the Standard menu to load its break rules and weekly limit.
- Enter the start and end time for each day and the length of the unpaid break.
- Add or remove days so the list covers one week (or any period you need).
- Optionally enter your hourly rate to see regular pay, overtime pay and the total.
