About the Overtime Pay Calculator
Overtime is the extra pay for hours worked beyond a normal limit. In many jobs the limit is 40 hours a week and the extra hours are paid at time and a half, which is 1.5 times your regular hourly rate. Some jobs pay double time on weekends, holidays or after a second threshold. This calculator takes your hourly rate, the hours you worked, the point where overtime starts and the overtime multiple, and returns your gross pay split into regular and overtime parts, your overtime rate per hour and the average per hour across the whole week. It helps you check a payslip or plan whether extra shifts are worth it.

How to use the Overtime Pay Calculator

Worked example
A worker earns 20 an hour and works 46 hours. The first 40 hours pay 800. The remaining 6 hours at time and a half pay 30 an hour, which is 180. Total gross pay is 980, an average of 21.30 per hour worked. If those 6 hours were paid at double time instead, the extra would be 240 and the week would total 1,040.
Keep in mind that some employers pay overtime in a different way, such as paying a fixed premium on top of the normal rate, averaging hours over several weeks or giving time off instead of extra money. Check your contract and your local labour rules, as these can change how the hours are counted. Where the rules are unclear, keeping your own timesheet is the best protection, and the Time Card Calculator on this site can total your shifts.
Is overtime worth it?

Checking your payslip
Compare the hours and rates on your payslip with your own records. Mistakes happen, particularly with changing shifts and bonuses. The calculator gives you a quick reference for what you should have earned before tax, so you can raise any difference with your employer early.

Frequently asked questions
How do I calculate overtime pay?
Pay normal hours at your usual rate. Multiply the hours over the threshold by your rate and the overtime multiple. At 20 an hour, 46 hours and time and a half after 40, you earn 800 for the first 40 hours plus 6 × 30 = 180, a total of 980.
What is time and a half?
It means 1.5 times the normal hourly rate. For an hourly wage of 20, time and a half is 30 an hour. Double time is 40.
When does overtime start?
It depends on your country, your contract and the job. In the US, many non-exempt employees get overtime after 40 hours in a work week. Some places also count daily hours. Check your contract and local law.
Is overtime pay taxed more?
Overtime is taxed as normal income, but it may push part of your pay into a higher tax band, and withholding on a bigger paycheck can look larger. At tax time, the effect usually evens out.
Do salaried workers get overtime?
It depends on their classification and local rules. Some salaried staff are exempt, others are not. If you are unsure, ask your employer or an employment advice service.
Can I use it for holiday or night pay?
Yes. Choose the multiple that applies, enter the hours, and use a high threshold if only some hours qualify. For more complicated rules, calculate each type of shift separately and add them.
