CalcHoursHow 7:30 AM to 4:30 PM is calculated
4:30 PM minus 7:30 AM is 9 hours of presence. The half hour is the only part people trip over: count the minutes to the next full hour first, then the full hours, then whatever is left. In 24-hour time it is 07:30 to 16:30, which makes the subtraction plain. Unpaid breaks are deducted from that. Federal law does not require a break; with a common 30-minute lunch you are paid for 8:30 hours (8.50 decimal hours).
| Unpaid break | Hours worked | Decimal |
|---|---|---|
| 0 min | 9:00 | 9.00 |
| 15 min | 8:45 | 8.75 |
| 30 min | 8:30 | 8.50 |
| 45 min | 8:15 | 8.25 |
| 60 min | 8:00 | 8.00 |
Per week and per month
Five days from 7:30 AM to 4:30 PM with a 30-minute lunch add up to 42:30 hours per week (42.50 h) and about 184.03 hours per month (factor 4.33). That is 2.50 hours over the 40-hour FLSA threshold, so a non-exempt employee earns time and a half on those. Enter your own breaks, blocks and pay rate in the calculator above; the Week tab totals the days and splits overtime.
