Time Card Calculator
Enter when you started, when you stopped and how long your unpaid break was, for each day from Monday to Sunday. The calculator adds up the hours per day and for the week, in hours and minutes and in decimal hours. Add an hourly rate to see gross pay. Add a weekly overtime threshold and a multiplier to split the week into regular and overtime hours.
Leave it empty for hours only.
Hours in the week above this count as overtime.
An overtime hour pays the hourly rate times this number.

Punch times count to the minute and are not rounded. An end time earlier than the start time counts as the next day, and the same time twice counts as zero. Decimal hours are rounded to two places. Pay is gross pay before taxes and deductions, worked out from the minutes and rounded to the cent. Your contract or local law sets your overtime rule. This calculator knows none and applies only the weekly threshold and the multiplier you type. With overtime, regular pay and overtime pay are each rounded to the cent and the gross pay is their sum. The calculator reads clock times with no date, so it does not know about daylight saving time. A night shift across a clock change is an hour shorter or longer than it shows.
How to use the Time Card Calculator
- Enter a start and an end time for each day you worked. Monday to Friday start with example times, so replace them. Clear both times on a day you did not work.
- Type the unpaid break for that day in whole minutes. An empty field counts as no break.
- If a shift ends after midnight, enter the end time as the clock showed it, such as 02:00. An end time earlier than the start time counts as the next day.
- Read the hours next to each day and the week below the table. The results update as you type, so there is no button to press.
- For gross pay, enter your hourly rate in dollars.
- For overtime, enter the weekly threshold in hours and the multiplier from your contract or from the law that applies to you. Both fields start empty and the calculator needs both. It then shows regular hours, overtime hours and the pay for each.
The time card math
Day = end − start − unpaid break Week = Monday + Tuesday + … + Sunday Decimal hours = minutes ÷ 60 Gross pay = week in hours × hourly rate With overtime: Regular hours = the smaller of the week and the threshold Overtime hours = week − regular hours Gross pay = regular hours × rate + overtime hours × rate × multiplier
The calculator counts in whole minutes and does not round your punch times. If the end time is earlier than the start time, it adds 24 hours to the end, so 22:00 to 06:00 is 8 hours. The same time twice counts as zero. Decimal hours are rounded to two places, but pay comes from the minutes. Pay is gross pay before taxes and deductions, rounded to the cent. With overtime, regular pay and overtime pay are each rounded to the cent and the gross pay is their sum. The overtime split looks at the week as a whole. Your contract or local law sets the overtime rule that applies to you. The calculator knows no such rule and uses only the threshold and the multiplier you type.
Worked example
These are example numbers, not a rule and not a suggestion. Monday to Friday from 09:00 to 17:00 with a 30 minute unpaid break is 7:30 a day and 37:30 for the week, or 37.50 decimal hours. The fields start with those times. Add Saturday from 22:00 to 02:00 with no break. The shift ends the next day, so Saturday counts 4:00 and the week comes to 41:30, or 41.50 hours. At an hourly rate of $18.50 the gross pay is $767.75. Now type a weekly threshold of 36 and a multiplier of 1.3. The calculator shows 36:00 regular hours and 5:30 overtime hours, regular pay of $666.00, overtime pay of $132.28 and gross pay of $798.28.
Frequently asked questions
How does the time card calculator handle a shift that ends after midnight?
Enter the end time as the clock showed it. When the end time is earlier than the start time, the calculator counts the shift as ending the next day and adds 24 hours to the end. 22:00 to 06:00 with a 30 minute break is 7:30. The whole shift counts on the day it started.
Does the calculator round punch times to the quarter hour?
No. It counts every minute as typed, so 08:53 to 17:07 is 8:14 before the break. If your time card uses rounded times, enter the rounded times.
What about a night shift when the clocks change?
The calculator reads clock times with no date, so it does not know about daylight saving time. On the night clocks go forward, 22:00 to 06:00 is 7 hours worked, and the calculator shows 8:00. Enter a start of 23:00 to get 7:00. On the night clocks go back, the same shift is 9 hours worked. Enter a start of 21:00 to get 9:00. Which hours your employer pays that night is up to your contract or local law.
Can I enter a 24-hour shift?
Split it over two days, because the same time twice counts as zero. For 08:00 to 08:00 the next day, enter 08:00 to 00:00 on the first day and 00:00 to 08:00 on the second. That is 16:00 and 8:00, or 24:00 in all.
Is pay worked out from the decimal hours?
No. It comes from the exact minutes, and only the pay is rounded, to the cent. 8:14 at $18.00 an hour is 494 ÷ 60 × 18 = $148.20. Multiplying the rounded 8.23 hours by 18 would give $148.14.
How do I convert hours and minutes to decimal hours?
Divide the minutes by 60 and add the hours. 7:30 is 7.50 hours. 8:14 is 8.23 hours, because 14 ÷ 60 = 0.2333. The calculator shows both forms for each day and for the week, with decimal hours rounded to two places.
Which overtime threshold and multiplier should I enter?
The ones in your contract or in the law that applies where you work. The calculator has no overtime rule of its own, and both fields start empty. It applies your threshold to the week as a whole. Hours up to the threshold are regular hours. The rest are overtime hours, paid at the hourly rate times your multiplier.
Is the pay figure what I take home?
No. It is gross pay before taxes and deductions, which is hours times rate plus the overtime part if you set one. For a US paycheck after taxes, use the take-home paycheck calculator.
What does the time card calculator leave out?
Daily overtime, double time, weekend and holiday rates and tips. It has one hourly rate and one weekly threshold. If your pay uses any of those, work that part out separately. A paid break needs no entry, because only unpaid break minutes come off the day.
