How to add up your work hours for the week
Work day by day: for each shift, subtract any unpaid break from the span between clock-in and clock-out, convert the result to decimal hours, then sum the seven days. The calculator above does all of it at once — untick Saturday and Sunday if they are days off, and every field updates the totals instantly.
Example week (Monday to Friday, 9–5 with a 30-minute lunch)
| Day | Shift | Break | Paid hours | Decimal |
|---|---|---|---|---|
| Mon | 9:00 – 17:00 | 30 min | 7h 30m | 7.50 |
| Tue | 9:00 – 17:00 | 30 min | 7h 30m | 7.50 |
| Wed | 9:00 – 17:00 | 30 min | 7h 30m | 7.50 |
| Thu | 9:00 – 17:00 | 30 min | 7h 30m | 7.50 |
| Fri | 9:00 – 17:00 | 30 min | 7h 30m | 7.50 |
| Week | 37h 30m | 37.50 |
At $18.50 per hour that week is 37.50 × $18.50 = $693.75 gross. Use the rate field in the calculator to see your own number as you type.
Watch out for these three payroll traps
- Decimal confusion: 7:30 on paper is 7.50 in decimals, not 7.30. See our decimal hours chart for every minute value.
- Paid vs unpaid breaks: only subtract breaks you are not paid for. Short rest breaks are usually paid time.
- Rounding rules: some employers round clock punches to the nearest quarter hour (7 minutes down, 8 minutes up). If yours does, expect small differences against this calculator.
Questions people ask
How do I calculate my work hours for the week?
For each day, subtract the start time from the end time and remove any unpaid break, then add the seven results together. Example: five 8-hour days minus a 30-minute unpaid lunch each day is 5 × 7.5 = 37.5 hours.
How many hours is a 9 to 5 job in a week?
9:00 AM to 5:00 PM is 8 hours of span. With a 1-hour unpaid lunch it is 7 paid hours per day, so a Monday-to-Friday week is 35 paid hours. With a paid 30-minute lunch it is 37.5.
Is lunch break paid or unpaid?
In the United States, bona fide meal breaks (typically 30 minutes or more where you are fully relieved of duty) are unpaid under federal law, but shorter rest breaks of 5–20 minutes are paid. State rules and company policy can differ, so check yours.
What counts as full-time hours per week?
Under the U.S. Affordable Care Act, 30 hours a week counts as full-time for employer coverage. Traditional full-time schedules are often 40 hours, and overtime rules kick in above 40 hours for non-exempt employees.
