How This Calculator Works

For each row, the tool converts start and end times to minutes since midnight, subtracts the unpaid break, and computes the net working minutes. If the end time is earlier than the start time, it assumes an overnight shift and adds 24 hours. All row totals are summed and displayed in both hours/minutes and decimal format.

Quick Questions

How do I convert decimal hours to hours and minutes?

Multiply the decimal portion by 60. For example, 7.75 hours = 7 hours and (0.75 × 60) = 45 minutes, so 7h 45m. This calculator does both conversions for you automatically.

Does this handle overnight shifts?

Yes. If your end time is earlier than your start time (e.g., start 10:00 PM, end 6:00 AM), the calculator assumes the shift crosses midnight and adds 24 hours to the end time automatically.

Should I enter paid or unpaid breaks?

Enter only unpaid break minutes. Paid breaks are part of your working time and should not be subtracted. If your employer pays for a 15-minute break, leave the break field empty or enter 0 for that time.

Why does my payroll use decimal hours instead of hours and minutes?

Decimal hours make wage math simpler. Multiplying 37.50 hours by $20/hour gives $750 directly. With hours and minutes you'd need an extra conversion step, which introduces rounding errors at scale.
