About Hours Worked Calculator
Add up the time between start and end times across as many shifts as you need. Each shift takes a start time, an end time and an unpaid break in minutes, and the calculator reports the total as hours and minutes (7:45), as decimal hours (7.75) and as minutes, plus the length of every shift. An end time earlier than the start is treated as an overnight shift that finishes the next day, so 22:00 to 06:00 is eight hours. Add an hourly rate to get a pay estimate before tax, rounded to the cent. It uses plain clock times, so it does not adjust for the night daylight saving starts or ends. Everything runs in your browser.

Hours Worked Calculator FAQ
How are overnight shifts handled?
If the end time is earlier than the start time, the shift is counted as ending the next day. 22:00 to 06:00 is 8 hours. Two identical times are rejected, because a 0-hour and a 24-hour shift look the same.
What are decimal hours and why do payroll systems want them?
Decimal hours express minutes as a fraction of an hour: 7 hours 45 minutes is 7.75, and 7 hours 20 minutes is 7.33. Payroll systems multiply hours by a rate, so a single decimal number is easier than hours and minutes. The tool shows both and rounds decimals to two places.
Does it handle unpaid breaks?
Yes. Enter the break in whole minutes and it is subtracted from that shift. A break as long as the shift is rejected. Paid breaks need no entry because they are simply part of the time worked.
Is the pay estimate accurate?
It is total time multiplied by your hourly rate, rounded to the cent, before tax. It does not apply overtime rules, premiums, rounding policies or deductions, which vary by employer and place, so treat it as a quick check.
Does daylight saving time change the result?
No. The calculator works with wall-clock times only. On the night clocks change, an overnight shift is really an hour longer or shorter than the clock difference. Adjust that shift by hand if it applies to you.
