Time Card Calculator
This time card calculator totals the hours you've worked across a week. Type the clock-in and clock-out times for each day, take off any unpaid break, and you'll get the daily hours, the weekly total, and the decimal hours payroll wants. Add your hourly rate and it'll estimate the gross pay too. It handles overnight shifts, it's free and private, and it updates as you type.
- Hours worked per day
- Weekly total
- Unpaid breaks

Overnight shifts count automatically. The pay figure is a gross estimate, before tax and deductions.
How do I calculate hours worked?
Each day is clock-out minus clock-in, less the unpaid break. The catch is that time isn't base ten, so 9:00 to 17:30 is 8 hours 30 minutes, not 8.3, and a 30 minute lunch trims it to a clean 8 hours. To total a week, you work out every day that way and add them up. This time card calculator turns each shift into minutes, subtracts the break, sums the days, and then converts the total back into hours and minutes plus the decimal hours your payroll needs. Type your rate and you'll see the gross pay alongside it.
Totaling a shift, step by step
Here's a 9:00 to 17:30 shift with a 30 minute lunch and a 20 dollar rate. It's the same path the tool runs for each day:
- 1
Find the gapFrom 9:00 to 17:30 is 8 hours and 30 minutes on the clock, or 510 minutes.
- 2
Take off the break510 minutes minus a 30 minute lunch leaves 480 minutes worked.
- 3
Convert to hours480 minutes divided by 60 is 8.0 hours, the clean decimal figure.
- 4
Work out the pay8.0 hours times 20 dollars is 160 dollars gross for the day.
Minutes to decimal hours
Here's how leftover minutes read in decimal hours, the form a payroll sheet expects. The calculator prints this for you, but it's handy to know the common ones, since they're the splits that turn up most on a shift. You'll spot them fast once they're familiar.
| Minutes | Decimal | Minutes | Decimal |
|---|---|---|---|
| 10 min | 0.17 | 35 min | 0.58 |
| 15 min | 0.25 | 40 min | 0.67 |
| 20 min | 0.33 | 45 min | 0.75 |
| 30 min | 0.50 | 50 min | 0.83 |
Frequently asked questions
Subtract the clock-in time from the clock-out time, then take off any unpaid break. So 9:00 to 17:30 is 8 hours 30 minutes, and after a 30 minute lunch you've worked 8 hours flat. This time card calculator does it for each day and adds the week up, so you don't have to wrestle with the 60-minute carry or convert anything by hand.
Work out each day on its own, then total the days. Add a row per shift, type the in and out times and the break, and the tool keeps a running weekly total at the top. It shows both the clock format, like 40:00, and decimal hours, like 40.0, since payroll usually wants the decimal version. You can run a five-day week or a longer stretch.
Yes. If the clock-out time is earlier than the clock-in, the tool reads it as crossing midnight and adds 24 hours, so a 22:00 to 06:00 shift comes out as 8 hours, not a negative number. That covers night shifts, split coverage, and anything that runs past midnight, and the break still gets subtracted the same way.
Divide the minutes by 60. Fifteen minutes is 0.25, thirty is 0.5, and forty-five is 0.75, so 8 hours 30 minutes is 8.5 decimal hours. Payroll systems run on the decimal form, which is why this time card calculator shows it next to the clock format. You don't have to do the division yourself, since the tool prints both.
Type your hourly rate and the tool multiplies it by the total decimal hours. So 40 hours at 20 dollars an hour is 800 dollars gross, before tax and deductions. It's a quick gross-pay estimate for planning, not a payslip, since it doesn't handle overtime rules, taxes, or withholdings, which vary by employer and state.
Yes to both. There's no sign-up, no limit on use, and nothing to install, because it runs right in your browser. The times and rate you enter stay on your device, so none of it gets sent to a server. Bookmark it and you'll have a quick timesheet whenever you need to tally a week.
