CalcHoursHow 8:30 AM to 3 PM is calculated
3 PM minus 8:30 AM is 6.5 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 08:30 to 15:00, 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 6:00 hours (6.00 decimal hours).
| Unpaid break | Hours worked | Decimal |
|---|---|---|
| 0 min | 6:30 | 6.50 |
| 15 min | 6:15 | 6.25 |
| 30 min | 6:00 | 6.00 |
| 45 min | 5:45 | 5.75 |
| 60 min | 5:30 | 5.50 |
Per week and per month
Five days from 8:30 AM to 3 PM with a 30-minute lunch add up to 30:00 hours per week (30.00 h) and about 129.90 hours per month (factor 4.33). That stays under the 40-hour FLSA overtime threshold. Enter your own breaks, blocks and pay rate in the calculator above; the Week tab totals the days and splits overtime.
What the day pays at common hourly rates
