How the hours are counted
Subtract the start from the end, then take off the break. From 9:00 AM to 5:30 PM is 8 hours 30 minutes; with a 30-minute unpaid break, that leaves 8:00. If the end time is earlier than the start — an overnight shift like 10:00 PM to 6:00 AM — the calculator adds 24 hours so the total comes out right.
Hours and minutes vs decimal hours
Payroll runs on decimal hours, not clock time. 8 hours 30 minutes is 8.5 hours, and 8 hours 15 minutes is 8.25 — you divide the minutes by 60. The classic mistake is to read 8:30 as "8.30"; it is not. This calculator shows both forms so you can copy the right one onto a timesheet.
Paid and unpaid breaks
A meal break is usually unpaid, so it is subtracted here. Short rest breaks may be paid depending on your employer and local law — if yours are, set the break to 0. This tool counts clock time only; overtime, shift differentials and rounding rules are set by your employer or jurisdiction.
