Enter clock-in and clock-out times and the unpaid break for each day. The calculator totals the week in hours and minutes and in decimal hours, splits regular hours from overtime, and works out gross pay if you add your hourly rate.
How hours worked are calculated
Hours worked = clock-out − clock-in − unpaid break. Example: in at 8:30 AM, out at 5:15 PM, with a 45-minute lunch. From 8:30 to 5:15 is 8 hours 45 minutes; minus the 45-minute lunch, that is 8:00 hours.
If a shift ends after midnight, say 10:00 PM to 6:00 AM, the calculator carries the time over midnight. Depending on your device settings, times show in 12-hour (AM/PM) or 24-hour format.
Converting minutes to decimal hours
Payroll usually needs decimal hours: divide the minutes by 60. The calculator shows both formats for each day and for the week.
| Hours:minutes | Decimal hours |
|---|---|
| 0:15 | 0.25 |
| 0:30 | 0.50 |
| 0:45 | 0.75 |
| 7:20 | 7.33 |
| 7:30 | 7.50 |
| 7:45 | 7.75 |
Overtime over 40 hours
Under the federal Fair Labor Standards Act, non-exempt employees must be paid at least 1.5 times their regular rate for hours worked over 40 in a workweek. Each workweek stands on its own: hours can’t be averaged over two or more weeks (U.S. Department of Labor).
The calculator starts overtime at 40 hours a week; change the threshold if your contract says otherwise. Some states go further: California, for example, also counts overtime by the day, which the calculator does not.
Breaks and lunch
Federal law doesn’t require lunch or coffee breaks. When an employer offers short breaks of 5 to 20 minutes, they count as paid work time; meal periods, usually 30 minutes or more, are not work time (U.S. Department of Labor). Enter only unpaid breaks in the Break column.
FAQ
Does it work for UK, Canadian or Australian time cards?
Yes for the hours: totals and decimal hours are the same everywhere. Set the overtime threshold to match your contract, and read gross pay with your own currency in mind.
How do I enter two breaks or a split shift?
Add the breaks up in the Break column, for example 30+15. For a split shift, enter the gap between the two parts as a break.
How do I enter a night shift?
Just enter the clock-in and clock-out times, for example 10:00 PM and 6:00 AM. When clock-out is earlier than clock-in, the calculator counts over midnight.
Can I track a whole month?
Yes, with the monthly timesheet: it lists every day of the month, totals the hours with overtime week by week, and prints on one page with signature lines, saves as PDF or opens in Excel.
