How to calculate overtime pay

An overtime calculator splits total hours worked into regular hours and overtime hours, then works out the pay for each. This free overtime calculator takes your total hours, a regular-hours threshold, an hourly rate, and a multiplier, and returns the split along with regular pay, overtime pay, and a combined total.

The threshold defaults to 40 hours and the multiplier defaults to 1.5, which is the common time-and-a-half setup in the United States, but both boxes can be changed for a different policy or a different country.

The time-and-a-half formula

This overtime pay calculator uses a simple formula: regular pay equals regular hours times the rate, and overtime pay equals overtime hours times the rate times the multiplier. Example: 45 total hours with a 40-hour threshold gives 40 regular hours and 5 overtime hours. At a rate of £20, regular pay is £800, overtime pay is 5 × £20 × 1.5 = £150, for a total of £950.

There is no statutory overtime rate in the UK — whether overtime is paid, and at what rate, depends entirely on your employment contract. The only legal floor is that your average pay must not fall below the National Minimum Wage. Workers are entitled to an uninterrupted 20-minute rest break when working more than 6 hours a day. Estimates only. Not legal advice.

Custom overtime threshold and multiplier

Not every working week or every state uses 40 hours and 1.5x. This weekly overtime calculator lets you set both values, so you can model a different regular-hours threshold or a double-time multiplier if your situation calls for it. The overtime hours calculator result updates based on whatever numbers you enter.

Common questions

What is the default overtime rule this calculator uses?

By default, hours over 40 in the total you enter are paid at 1.5 times the regular rate, which is a common U.S. convention. Both the 40-hour threshold and the 1.5 multiplier can be changed.

Can I use a different overtime multiplier?

Yes. Change the multiplier field to whatever rate applies to your situation, such as 2.0 for double time.

Does this calculator know my state's overtime rules?

No. It only applies the threshold and multiplier you enter. Overtime rules vary by state and situation, so confirm the right numbers for your case.

Is this overtime calculator free?

Yes. It is completely free, with no sign-up and no limit on how many times you use it.
