Hours calculator
Enter when you started and finished, take off the unpaid break, and you get the hours both ways: as a decimal for payroll, and as hours and minutes for everything else. Add a rate and it works out the pay.
How to calculate hours worked
The decimal figure is the one payroll wants, and it is where mistakes happen: 7 hours 45 minutes is 7.75 hours, not 7.45. Anyone converting by moving the decimal point is quietly losing themselves eighteen minutes a shift. The other trap is the overnight shift; 22:00 to 06:00 is eight hours, and a calculator that subtracts naively reports minus sixteen. This one wraps past midnight rather than going negative. Whether your break is actually unpaid depends on your contract and your jurisdiction; in the US, breaks under twenty minutes are generally paid under federal rules, but state law and your contract can differ.
Questions
Divide by 60. Forty-five minutes is 0.75 hours, not 0.45, that mistake costs eighteen minutes a shift.
Yes. A finish time earlier than the start is treated as the next day, so 22:00 to 06:00 is eight hours.
If it is unpaid, yes. Short breaks are often paid: check your contract, since the rules differ by country and state.
Because pay is hours times rate, and h:mm does not multiply. 7:45 times £12 is meaningless; 7.75 times £12 is £93.
Use the weekly hours calculator, which takes one line per day and splits out overtime.
No. It is calculated in the page and nothing is sent anywhere.
