CalcHoursHow 8 AM to 5:30 PM is calculated
5:30 PM minus 8 AM is 9.5 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 08:00 to 17:30, 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 9:00 hours (9.00 decimal hours).
| Unpaid break | Hours worked | Decimal |
|---|---|---|
| 0 min | 9:30 | 9.50 |
| 15 min | 9:15 | 9.25 |
| 30 min | 9:00 | 9.00 |
| 45 min | 8:45 | 8.75 |
| 60 min | 8:30 | 8.50 |
Per week and per month
Five days from 8 AM to 5:30 PM with a 30-minute lunch add up to 45:00 hours per week (45.00 h) and about 194.85 hours per month (factor 4.33). That is 5.00 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.
What the day pays at common hourly rates
With a 30-minute unpaid lunch, 9:00 hours are paid. The table works that through for common rates; the federal minimum wage is $7.25, most states are higher.
| Hourly rate | Day (9:00 h) | Week (5 days) |
|---|---|---|
| $15.00 | $135.00 | $675.00 |
| $18.00 | $162.00 | $810.00 |
| $20.00 | $180.00 | $900.00 |
| $25.00 | $225.00 | $1,125.00 |
| $30.00 | $270.00 | $1,350.00 |
