About the Time Card Calculator
A time card records when you start and finish work each day. This time card calculator adds them up. Type one line for each day with the start time, the end time and the unpaid break in minutes, and it gives the hours worked each day and in total, in both hours and minutes and in decimal hours that payroll systems use. Set when overtime starts and the pay multiplier, and enter an hourly rate to see regular and overtime hours and estimated pay. It understands 24-hour and 12-hour times, and shifts that finish after midnight. It suits employees checking a payslip, freelancers billing by the hour and managers filling in timesheets.

Checking your pay
Compare the total with your payslip. Common reasons for a difference are rounding rules, a paid or unpaid break treated differently, overtime counted per day, or hours before a threshold being paid at a different rate. Keep your own record of start and finish times, since it is evidence if there is a mistake. This tool gives estimates and does not replace your employer's payroll.

Frequently asked questions
How do I calculate hours worked?
Subtract the start time from the end time and then subtract unpaid breaks. A shift from 09:00 to 17:30 with a 30-minute break is 8 hours 30 minutes minus 30 minutes, which is 8 hours. The calculator does this for every line and adds them up.
How do I convert hours and minutes to decimal hours?
Divide the minutes by 60 and add to the hours. 7 hours 45 minutes is 7.75 hours, and 8 hours 20 minutes is 8.33 hours. The result shows both versions, so you can enter the one your payroll form asks for.
How do I enter a night shift?
Write the real start and end times. If the end time is earlier than the start time, the tool assumes the shift finished the next day. For example 22:00 to 06:00 counts as 8 hours.
How is overtime calculated?
Hours above the threshold you set, such as 40 a week, count as overtime and are paid at your rate times the multiplier. In this tool overtime is worked out on the whole period you enter. Some employers and countries count overtime by the day instead, so check your contract.
Can I enter times in AM and PM?
Yes. Write 9am or 5:30pm, or use 24-hour times like 17:30. Both can be mixed on different lines. Times without AM or PM are read as 24-hour.
Does it handle paid breaks?
Enter only unpaid break minutes. If a break is paid, leave it out, so the time stays in the total. If your employer rounds hours to the nearest quarter hour, adjust the times to match what your payroll records.
