Hours Worked Calculator (Time Card)
Use it as a simple weekly time card and add up the hours you worked. Enter your start and end times and any unpaid breaks for each day to see the total in hours and minutes, in decimal hours, and your pay if you add an hourly rate.

How the hours are calculated
For each day, the calculator subtracts the start time from the end time and then subtracts the unpaid break. Leave both times empty on days you didn't work. If the end time is earlier than the start time, it treats it as a night shift that ends the next day.
It works like a paper time card or a timesheet: write down when you clock in and out each day, and the calculator does the math. Keep your employer's official records too, since they decide how your time is rounded and paid.
The formulas
Hours per day = end − start − break
Pay = total decimal hours × hourly rate
Worked example
- Monday, 8:00 AM to 4:45 PM with a 45-minute break: 8 h 45 min − 45 min = 8 h 00 min.
- Tuesday, 7:30 AM to 12:00 PM with no break: 4 h 30 min.
- Wednesday, night shift from 10:00 PM to 6:00 AM with a 30-minute break: 8 h − 30 min = 7 h 30 min.
Total: 8 h 00 min + 4 h 30 min + 7 h 30 min = 20 h 00 min, which is 20.00 decimal hours. At 15 an hour, that's 300.00.
Frequently asked questions
How do I convert minutes to decimal hours?
Divide the minutes by 60. For example, 7 hours and 45 minutes is 7 + 45 ÷ 60 = 7.75 hours. Payroll usually uses decimal hours, which is why the calculator shows both.
Does it work for night shifts?
Yes. If the end time is earlier than the start time, the calculator assumes the shift ends the next day. For example, 10:00 PM to 6:00 AM is 8 hours before the break.
Should I enter paid breaks?
No. Enter only unpaid breaks, such as an unpaid lunch. Paid breaks count as time worked, so leave them out of the break column.
Does it calculate overtime?
No. It adds up all the hours at the same rate. To pay overtime hours at a higher rate, use our overtime calculator.
