Work hours calculator

Hours actually worked from clock-in and clock-out times, with breaks taken out

Your day

Breaks are simply subtracted — whether they are paid is a matter for your contract.

Time at work is not time worked

Nine to six is nine hours on site, but the lunch hour belongs to neither your pay nor your overtime count: nine hours minus 60 minutes leaves eight worked. Pay, overtime and weekly limits are all reckoned on the worked figure, which is why this calculator keeps the two numbers apart.

Shifts that cross midnight

If the clock-out time is earlier than the clock-in, the calculator assumes you finished the next day: 22:00 to 06:00 is eight hours, not minus sixteen. Nothing needs switching — a night shift goes through the same arithmetic as a day shift.

Small daily gaps grow over a week

The weekly line multiplies one day by five, and that is exactly why it is worth a look: fifteen unpaid minutes a day seems like nothing, but over a five-day week it is an hour and a quarter, and over a year roughly a week and a half of work.

Frequently asked questions

Q. Are breaks paid or unpaid?

That depends on your country and your contract — many places pay short breaks but not the meal break. This calculator only does the arithmetic: whatever minutes you enter come out. If your breaks count as working time, enter 0.

Q. I take several breaks. What do I enter?

Add them up and enter the total in minutes. Two fifteen-minute pauses and a half-hour lunch make 60. How the minutes were spread across the day makes no difference to the sum.

Q. My week is not five days.

The weekly line assumes five equal days because that is the most common pattern. For four or six days, multiply the daily result yourself — or read the line as what a five-day week on this schedule would come to.
