Frequently asked questions
How do I calculate hours worked in a week?
Enter each day's start and finish plus any unpaid break, and the total comes back in hours and minutes as well as decimal hours. Decimal is the format payroll systems expect: 7 hours 45 minutes is 7.75, not 7.45, and that confusion is a common source of pay errors.
How do I handle a shift that runs past midnight?
Enter the times as worked and the overnight rollover is detected, so 21:00 to 05:00 returns 8 hours rather than a negative number.
Should breaks be deducted?
Unpaid breaks are deducted; paid ones are not. Which is which depends on your jurisdiction and contract — in many places a short rest break is paid while a longer meal break is not, so check the rule that applies to you.
How do I calculate overtime?
Work out total hours first, then apply your overtime threshold — commonly anything above 40 in a week, though daily thresholds apply in some jurisdictions. The multiplier is set by contract or statute rather than by any general formula.
