Overtime pay is simple to understand and easy to get wrong. The general idea is that nonexempt employees earn a higher rate for hours worked beyond a standard threshold. Getting the calculation right matters because overtime errors are one of the most common wage claims.

Rules differ by location

This guide explains the general overtime formula. Exact thresholds, exemptions, and rates come from the law where you operate, so confirm with an employment lawyer or your state or national labor agency.

The standard overtime formula

In many countries, overtime is paid at 1.5 times the regular rate of pay for hours over a weekly threshold, commonly 40 hours. The formula is:

Overtime pay = hourly rate x 1.5 x overtime hours

Here is a simple example. An employee earns 20 per hour and works 45 hours in one week. The first 40 hours pay normally, and the extra 5 are paid at overtime rate.

Regular pay = 40 x 20 = 800
Overtime rate = 20 x 1.5 = 30
Overtime pay = 5 x 30 = 150
Total = 800 + 150 = 950

Working with salaried nonexempt employees

Overtime is not only for hourly staff. Salaried employees who are classified as nonexempt are also entitled to overtime. For them the regular rate is worked out from their salary, and overtime is paid on top of it. The exact method depends on how the pay period is structured, so get the details right for your situation.

Track overtime before you calculate it

The calculation is only as good as the hours you record. Reliable time tracking is what makes overtime accurate, especially for remote and hybrid teams. If employees declare overtime hours with a date and reason, and a manager approves them, the pay calculation starts from solid numbers.

Keep an approval trail

When overtime is submitted and approved through a system, you have a record of who worked the hours and who signed off. That is useful for payroll and for resolving disputes later.

Frequently asked questions

Is overtime always 1.5 times the rate?
The 1.5x multiplier is the common standard, but some situations use different rates or rules. Confirm the rules for your location and workforce.
Do salaried employees get overtime?
Only salaried employees who are classified as nonexempt and are not covered by an exemption. Exempt employees generally do not receive overtime. Classification matters and should be verified.
How do I avoid overtime calculation mistakes?
Track hours accurately, apply the correct rate to the right hours, and keep a clear written policy. Many teams use software to reduce manual math errors.
What counts as an hour worked for overtime?
Time actually worked, which usually excludes meal breaks and commute. Rules vary, so confirm what counts in your location.

The bottom line

Overtime pay follows a simple idea: a higher rate for hours beyond a threshold. The details, thresholds, and exemptions come from the law in your area, so verify them and track hours accurately. Get the formula and the records right, and overtime stops being a source of disputes.
