CalcHoursHow 7 AM to 3:30 PM is calculated
3:30 PM minus 7 AM is 8.5 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 07:00 to 15:30, 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 8:00 hours (8.00 decimal hours).
| Unpaid break | Hours worked | Decimal |
|---|---|---|
| 0 min | 8:30 | 8.50 |
| 15 min | 8:15 | 8.25 |
| 30 min | 8:00 | 8.00 |
| 45 min | 7:45 | 7.75 |
| 60 min | 7:30 | 7.50 |
Per week and per month
Five days from 7 AM to 3:30 PM with a 30-minute lunch add up to 40:00 hours per week (40.00 h) and about 173.20 hours per month (factor 4.33). That is exactly 40 hours, the 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
With a 30-minute unpaid lunch, 8:00 hours are paid. The table works that through for common rates; the federal minimum wage is $7.25, most states are higher.

| $15.00 | $120.00 | $600.00 |
