Time Card Calculator
Enter your clock-in time, clock-out time and unpaid break. For the default shift the calculator shows 8 hours per day and 40 hours per week.
How the time card calculator works
The calculator turns a clock-in time, a clock-out time and an unpaid break into hours worked. Times use the 24-hour clock, so 5:30 pm is hour 17 and minute 30. If the clock-out time is earlier than the clock-in time, the calculator treats the shift as running past midnight and adds 24 hours.
It then multiplies one day by the number of days you work, splits the week into regular and overtime hours at the threshold you set, and prices overtime at 1.5 times your rate. Decimal hours, such as 7.5, are what payroll systems usually want, and the h:mm line shows the same total as hours and minutes.
The formulas
Example: Clocking in at 9:00 and out at 17:30 with a 30-minute break gives 8 hours a day, or 40 hours over five days. That includes 0 hours of overtime, so the gross weekly pay at $20 an hour is $800.00. The numbers are an illustration.
Things to check
Overtime rules depend on where you work. The federal rule counts hours over 40 in a workweek, but some states also count daily hours, and some employers pay different multipliers, so change the threshold to match your pay policy. Whether a break is paid also depends on its length and your employer. The Department of Labor rules on hours worked are in 29 CFR Part 785. This tool gives gross pay before taxes and deductions.

Frequently asked questions
How do I calculate hours worked from clock-in and clock-out?
Subtract the clock-in time from the clock-out time, subtract any unpaid break, and divide the minutes by 60. For the default shift the result is 8 hours.
How do I convert minutes to decimal hours?
Divide the minutes by 60. Thirty minutes is 0.5 hours and 45 minutes is 0.75 hours.
What if my shift crosses midnight?
Enter the real clock-in and clock-out times. When the out time is earlier than the in time, the calculator adds 24 hours automatically.
Does this calculator include taxes?
No. It shows gross pay before taxes and deductions. Use the paycheck calculator for an estimate of take-home pay.
Can I change the overtime rule?
Yes. Set the weekly hours at which overtime starts. The multiplier is fixed at 1.5 times your rate.
