What it does
The calculator adds up a week of working time. For each day from Monday to Sunday you enter a start time, an end time and a break, and it shows the week’s total in hours and minutes, the same total in decimal hours, the days worked and the breaks. Add an hourly rate and it shows the pay too. The answer updates as you type, and the sum under it shows how it was worked out.
How to use it
- The page opens with an example week: Monday to Friday from 09:00 to 17:30 with a 30 min break, which comes to 40 h 00 min.
- Change the start and end times for each day you worked. Leave both blank for a day off.
- Set each day’s break in minutes.
- Type an hourly rate if you’d like the pay worked out. It’s optional.
- Open More options to round each day to 5, 6 or 15 min.
- Select Copy result to put the hours, each day and the totals on your clipboard.
The calculator remembers the breaks, the hourly rate and the rounding on this device. The times aren’t kept: each visit starts from the example week.
How it’s calculated
Each day’s worked time is its End time minus its Start time minus its break. When the End time is before the Start time, the shift ends the next day, so a day has 24 hours added: 22:00 to 06:00 is 8 h, and 7 h 30 min after a 30 min break. With rounding on, each day’s worked time then goes to the nearest step, halves up.
The total is the sum of the days. Decimal hours are the total minutes divided by 60, in hundredths of an hour, rounded half up. The pay is the decimal hours times the hourly rate, rounded half up to the cent: 40.00 h × 15.00 = 600.00.
Times are read as clock times, so a daylight saving change during a night shift isn’t counted. There’s no overtime, and no taxes or deductions are taken off.
Good to know
- Times are 24-hour clock times from 00:00 to 23:59, in hours and minutes. Your browser may show them with AM and PM.
- A day with only a start time or only an end time isn’t counted. Its row says which time is missing, so you can fill it in or clear it.
- The Start and End times of a day can’t be the same. For a shift past midnight, the End time is before the Start time.
- A break is a whole number of minutes from 0 to 1,440, and it must be shorter than that day’s shift.
- The longest day is 23 h 59 min, so the longest week is 167 h 53 min.
- The hourly rate can be anything from 0 to 1,000,000. Amounts are shown with 2 decimals and no currency, so the pay is in whatever currency the rate is.
Privacy
Everything is calculated in your browser, on your device. Nothing you type is uploaded. The times aren’t stored; only the breaks, the hourly rate and the rounding are kept, in this browser’s storage, so the page can show them again.
