A simple work hours calculator for time cards and timesheets. For each day enter when you started, when you finished and how long your break was; the calculator adds everything up in hours and minutes and in decimal hours, and can multiply by your hourly rate.
How are work hours calculated?
The hours worked in a day are the end time minus the start time minus unpaid breaks. If the shift passes midnight, 24 hours are added to the end time first. The daily results are then summed to get the total for the week or month.
Payroll systems often want decimal hours (for example 7.75 instead of 7:45). Decimal hours are the total minutes divided by 60, which is what this calculator shows next to the h:mm total.
How to use it
- Enter the start and end time for each day, and the unpaid break in minutes.
- Add rows for more days or shifts; overnight shifts are handled automatically.
- Read the total in h:mm and decimal hours, and enter an hourly rate to see the earnings.
Frequently asked questions
- How do I convert hours and minutes to decimal hours?
- Divide the minutes by 60 and add the hours: 7:45 is 7 + 45/60 = 7.75 hours. The calculator does this for the total automatically.
- Does it handle night shifts?
- Yes. If the end time is earlier than the start time the shift is treated as running past midnight, for example 22:00 to 06:00 is 8 hours before breaks.
