Time Card Calculator

Total Your Hours Worked From Daily Punches

The Tools Kit's free Time Card Calculator turns daily clock-in and clock-out times into total hours worked for the week or pay period. Enter a time in, time out, and unpaid break for each day, and it adds up the hours, splits regular time from overtime, and, if you add an hourly rate, estimates gross pay. It works as a weekly timesheet calculator or a biweekly one, handles overnight shifts, and shows every figure in decimal hours ready for payroll.

Daily hours = time out − time in − unpaid break. On a week of five 8:00 to 17:30 shifts with a 30-minute lunch, each day is 9 hours and the week is 45 hours: 40 regular and 5 overtime.

How to Use the Time Card Calculator

1. 1

   Choose the pay period and settings

   Pick Weekly (7 days) or Biweekly (14 days), 24-hour or 12-hour AM/PM time format, and optional rounding of 5, 6, or 15 minutes.

2. 2

   Enter each day’s punches

   Type the time in, time out, and unpaid break minutes for every day worked. Leave days off blank; they are skipped. A shift that ends after midnight is handled automatically.

3. 3

   Set the overtime rule

   Keep federal overtime after 40 hours per workweek at 1.5× or 2×, switch it off, or turn on California daily overtime (over 8 hours at 1.5×, over 12 hours at 2×).

4. 4

   Add an hourly rate (optional)

   Enter your hourly wage to see gross pay, with regular hours at your rate and overtime hours at the overtime multiplier, before taxes and deductions.

5. 5

   Review, print, or clear

   Check the hours column and the totals, then use Print to produce a time card sheet or save it as a PDF from your browser’s print dialog.

If a day has only one of the two times filled in, a time in the wrong format, or a break longer than the shift, an error message appears below the table and the totals stay hidden until you fix it.

How to Calculate Hours Worked and Convert to Decimal

Payroll multiplies hours by a rate, so hours and minutes have to be converted to decimal hours first. Divide the minutes by 60: 15 minutes is 0.25, 30 minutes is 0.5, and 45 minutes is 0.75. A common mistake is reading 7 hours 30 minutes as 7.30, which underpays by 12 minutes compared with the correct 7.5 hours.

• Standard shift: 9:00 AM to 5:30 PM with a 30-minute break is 8 hours.
• Overnight shift: 22:00 to 06:00 with a 30-minute break is 7.5 hours; the calculator adds 24 hours when time out is earlier than time in.
• Long shift: 06:00 to 20:00 with a 30-minute break is 13.5 hours.

If you are paid a salary rather than by the hour and want to know what your time is worth, the salary to hourly calculator converts an annual figure into an hourly rate you can enter here.

Overtime on a Time Card: Weekly, Biweekly, and California Rules

Under the federal Fair Labor Standards Act, non-exempt employees earn overtime for hours over 40 in a workweek. With overtime on, the calculator counts the first 40 hours of the week as regular and the rest at 1.5×, or 2× if your employer pays double time. At $20 an hour, the 45-hour week above pays 40 × $20 + 5 × $30 = $950 gross. For a deeper look at overtime rates on their own, use the overtime pay calculator.

Biweekly mode keeps the two weeks separate, because overtime is owed per workweek, not per pay period. If you work 54 hours in week one and 24 in week two, the 78-hour total is under 80, but week one still has 14 overtime hours: 64 regular hours and 14 overtime hours, or $1,700 gross at $20 an hour.

California daily overtime mode splits each day instead: up to 8 hours regular, hours over 8 up to 12 at 1.5×, and hours over 12 at 2×. Four 10-hour days total 40 hours, which is no overtime under the weekly rule ($800 at $20 an hour) but 32 regular and 8 overtime hours in California mode ($880). A 13.5-hour day splits into 8 regular, 4 at 1.5×, and 1.5 at 2×. This mode applies the daily thresholds only; it does not add California's weekly 40-hour or seventh-consecutive-day rules.

Time Rounding and the 7-Minute Rule

Many employers round recorded time to a set interval. The calculator offers 5, 6, and 15 minute rounding; 6 minutes matches tenth-of-an-hour billing, and 15 minutes follows the common 7-minute rule, where 1 to 7 minutes round down and 8 to 14 minutes round up.

Rounding is applied to the length of each shift, before the break is subtracted. With 15-minute rounding and a 30-minute break, 8:00 to 16:52 (8 hours 52 minutes) rounds to 8 hours 45 minutes and counts as 8.25 hours, while 8:00 to 16:53 rounds up to 9 hours and counts as 8.5 hours. Leave rounding on None to total exact minutes.

From Hours to Pay

The gross pay figure is hours × hourly rate, with overtime hours multiplied by 1.5 or 2. It is earnings before any deductions. To see what lands in your bank account after federal and state withholding, carry the gross amount into the paycheck calculator, and to see what a steady weekly schedule adds up to over a year, try the hourly to salary calculator.

Contractors who bill by the hour can total a week of work here and then turn the hours into a bill with the invoice generator. For counting the calendar days in a pay period or between two dates, the days calculator handles that, and the full set of pay and finance tools is in the calculator tools hub.
