Time Card Calculator
Enter when you clocked in and out each day, subtract unpaid breaks, and get your total hours for the week in hours and minutes and in decimal.
How we calculate it
- Hours worked = clock-out time − clock-in time (plus 24 hours when you clock out the next day)
- Paid time = hours worked − unpaid break
- Week total = the sum of the days, kept in exact minutes
- Decimal hours = minutes ÷ 60, shown to two places
- Pay (if you add a rate) = regular hours × rate + overtime hours × rate × multiplier, before taxes and deductions
Rounding, if you turn it on, moves each clock-in and clock-out to the nearest step before the subtraction, so it can go up or down.
Not legal or payroll advice. Federal law generally requires 1.5 times the regular rate for hours over 40 in a workweek for covered, non-exempt employees; some jobs are exempt and state rules can differ. See the U.S. Department of Labor overtime page or your state labor agency.
This is a worksheet for checking your own hours. It is not a pay stub or a payroll record.

Frequently asked questions
How do I calculate hours on a time card?
For each day, subtract the clock-in time from the clock-out time, then subtract any unpaid break. Add the days together for the week. To turn minutes into decimal hours, divide by 60, so 7 hours 45 minutes is 7.75 hours. The calculator does this for every row and shows both formats.
Should lunch be subtracted from my hours?
Under federal rules, a real meal break, usually 30 minutes or more when you are completely relieved of duty, generally is not paid work time, while short rest breaks of a few minutes usually are. Some states have their own meal and rest break rules, so check with the U.S. Department of Labor or your state labor agency.
How do I convert minutes to decimal hours?
Divide the minutes by 60. 15 minutes is 0.25 hours, 30 minutes is 0.5, 45 minutes is 0.75 and 20 minutes is about 0.33. The calculator keeps the exact minutes and rounds only the displayed decimal to two places, so weekly totals do not drift from small rounding errors.
What if a shift goes past midnight?
When the clock-out time is earlier than the clock-in time, the calculator treats it as the next day and adds 24 hours. A shift from 10:00 PM to 6:30 AM with a 30-minute break counts as 8 hours. A shift longer than 24 hours needs two rows, one for each day.
Is this a pay stub?
No. It adds up the hours you enter and, if you add a rate, shows gross pay before taxes and deductions. It does not withhold taxes and does not create payroll records. Use it to check your own hours or plan a schedule, and use your employer's or your payroll system's records as the official ones.
