Overtime calculator
Your hours, your rate, your contract's multiplier.
Enter the hours worked, the hourly rate and the multiplier that applies to overtime. You get the overtime pay on its own, the regular pay beside it and the gross total. The calculator does not assume a 40-hour week or a 1.5 multiplier, because the threshold and the rate change with the country, the contract and the collective agreement. If your timesheet only gives a total, switch the selection at the top and enter the hour at which overtime starts.

Overtime pay
The calculation runs in your browser. Nothing is sent anywhere.
Your hours
The threshold and the multiplier come from your contract, so the calculator asks for them instead of assuming them.
Pay
Gross figures, before tax and deductions.
Choose the overtime multiplier your contract uses. Nothing is assumed here, so there is no result until you pick one.
How it works
Three inputs, and one rule the calculator refuses to guess.
Enter the hours
Give regular and overtime hours separately, or give the total together with the hour at which overtime starts.
Enter the hourly rate
Use the gross rate in whatever currency you are paid in. Nothing is converted, so the result comes back in the same currency.
Pick the multiplier
1.5 and 2 are common, but there is no default here. Take the figure from your contract or your last payslip.
Why this one
Three things overtime calculators usually get wrong.
No hidden 40-hour assumption
Most calculators bake in a 40-hour week and a 1.5 rate, then show a number that looks like yours. Here the threshold and the multiplier are yours to set, so the answer matches your contract instead of somebody else's.
The overtime hour gets its own price
You see what one overtime hour is worth and what share of the total pay comes from overtime. That share is the figure to look at before approving another week of it.
Works from a single total
If all you have is the total hours, enter the threshold and the split is done for you. No second calculator, no arithmetic in your head.
Frequently asked questions
How do I calculate overtime pay?
Multiply the overtime hours by the hourly rate, then by the overtime multiplier. Six overtime hours at a rate of 20 with a 1.5 multiplier come to 6 x 20 x 1.5, which is 180. Regular hours are paid at the plain rate and added on top.
What is time and a half?
Time and a half is a multiplier of 1.5: the overtime hour is paid at the normal rate plus half of it again. A rate of 20 becomes 30 for that hour. Double time is a multiplier of 2.
How many hours before overtime starts?
It depends on where you work and what you signed. In the United States a weekly threshold of 40 hours is the common case, though it does not apply to every role, and some states also count overtime by the day. Elsewhere the figure differs again. That is why this calculator asks you for the threshold instead of assuming one. Check your contract or your employer's policy for the number that applies to you.
Is overtime calculated on gross or net pay?
On gross. The multiplier applies to the gross hourly rate, and tax and deductions come off afterwards. Every figure this calculator returns is a gross figure.
Is my data stored anywhere?
No. The calculation runs in your browser and the entries stay on your device. Nothing is sent to a server.

The multiplication is not the hard part
Once the hours are settled, the rest is one line of arithmetic. Worktivity records start, end and break automatically while people work, so the overtime figure comes from what actually happened rather than from memory at the end of the month.
