Overtime Pay Calculator
Under the federal Fair Labor Standards Act, most hourly employees must be paid at least one and a half times their regular rate for hours worked beyond 40 in a workweek. This calculator turns those rules into a clear figure: it multiplies your regular hourly rate by 1.5 to get the overtime rate, then multiplies that by the number of overtime hours to find your overtime pay. Enter your hourly rate and the overtime hours worked, and the tool returns the overtime rate per hour and the total extra pay earned. Seeing the overtime rate alongside the total makes it easy to check a paycheck or estimate the value of additional hours before agreeing to them. The multiplier of 1.5 is kept editable in case a contract or state rule sets a higher premium, but the federal floor is time and a half. This tool covers the overtime portion only; add it to your regular pay to get gross pay. The US Department of Labor administers the FLSA rules, and the IRS governs the tax withheld. Every figure here is computed deterministically from the formula shown in full below, with a worked example that reconciles exactly to the calculator so you can follow each step.
Overtime is paid at time and a half: overtime pay = 1.5 times rate times overtime hours. At $20.00 an hour for 10 overtime hours, the overtime rate is $30.00 and total overtime pay is $300.00.
Overtime Pay formula
Overtime pay = rate x multiplier x overtime hours
rate = your regular hourly pay
multiplier = overtime premium (federal minimum 1.5)
overtime hours = hours worked beyond 40 in the workweek
The Fair Labor Standards Act sets the federal overtime premium at one and a half times the regular rate; some states or contracts require more, which you can enter as a higher multiplier.
Worked example
Find the overtime pay for 10 overtime hours at a 20.00 hourly rate and the standard 1.5 multiplier.
- Overtime rate: 20.00 x 1.5 = 30.00 per hour
- Multiply by overtime hours: 30.00 x 10 = 300.00
- Total overtime pay = 300.00
These are the calculator's default inputs, so the result above matches the widget exactly.
Overtime Pay Calculator: frequently asked questions
What is the federal overtime rule?
Under the Fair Labor Standards Act, non-exempt employees must receive at least 1.5 times their regular rate of pay for hours worked over 40 in a single workweek. Some states have additional daily overtime rules.
Does overtime apply over 8 hours a day?
Not under federal law, which counts overtime weekly past 40 hours. A few states, such as California, require daily overtime after 8 hours. Check your state rules, and adjust the hours and multiplier inputs accordingly.
Is overtime taxed differently?
No. Overtime pay is taxed as ordinary wages. It can appear to be taxed more heavily only because a larger paycheck may push more of your pay into a higher withholding bracket for that period.
Who is exempt from overtime?
Certain salaried executive, administrative, professional and outside-sales employees who meet duties and salary-threshold tests are exempt. The Department of Labor publishes the current tests and thresholds.
What is the overtime pay formula?
Overtime pay equals the hourly rate times the multiplier times overtime hours. At 20.00 an hour for 10 hours at 1.5x, overtime pay is 300.00.
