Overtime Calculator
Overtime pay = hourly rate × 1.5 × overtime hours (when your overtime rate is time and a half). Example: $20/h with 5 overtime hours = $20 × 1.5 × 5 = $150, in addition to your regular pay for the first 40 hours.

Overtime pay examples at $20 an hour
Time and a half after 40 hours in the week:
| Hours in the week | Regular hours | Overtime hours | Regular pay | Overtime pay | Total gross |
|---|---|---|---|---|---|
| 38 hours | 38:00 | 0:00 | $760.00 | $0.00 | $760.00 |
| 41 hours | 40:00 | 1:00 | $800.00 | $30.00 | $830.00 |
| 45 hours | 40:00 | 5:00 | $800.00 | $150.00 | $950.00 |
| 50 hours | 40:00 | 10:00 | $800.00 | $300.00 | $1,100.00 |
| 55 hours | 40:00 | 15:00 | $800.00 | $450.00 | $1,250.00 |
45 hours at $20: regular 40 × $20 = $800.00, overtime 5 × ($20 × 1.5) = 5 × $30 = $150.00, total $950.00.
How is overtime calculated?
- Add up the hours worked in the workweek. Use the time card calculator if you have start and end times.
- Overtime hours = total hours − 40 (if the total is over 40).
- Overtime rate = hourly rate × multiplier. Time and a half is × 1.5, double time is × 2.
- Gross pay = regular hours × hourly rate + overtime hours × overtime rate.
What the federal rule says
Unless specifically exempted, employees covered by the Fair Labor Standards Act must receive overtime pay for hours worked over 40 in a workweek at a rate not less than time and one-half their regular rates of pay. The workweek is a fixed, regularly recurring period of 168 hours that can begin on any day, and averaging hours over two or more weeks is not permitted (U.S. Department of Labor, Fact Sheet #23, revised October 2019).
Overtime and taxes
This calculator shows gross pay. If you type a flat tax percentage it subtracts that share to estimate take-home pay, but it has no tax tables. A federal deduction for part of overtime pay exists for some taxpayers; see the no tax on overtime calculator for what the IRS says.
Frequently asked questions
How do I calculate overtime pay?
Overtime pay = hourly rate × overtime multiplier × overtime hours. With time and a half the multiplier is 1.5. At $20 an hour, 5 overtime hours pay $20 × 1.5 × 5 = $150, in addition to your regular pay for the first 40 hours.
What does time and a half mean?
It means your overtime hours are paid at 1.5 times your regular hourly rate. The Fair Labor Standards Act sets time and a half as the minimum for covered, non-exempt employees for hours over 40 in a workweek (U.S. Department of Labor, Fact Sheet #23).
Is overtime averaged over two weeks?
No. Under the FLSA each workweek stands alone, and averaging hours over two or more weeks is not permitted. If you work 45 hours in week one and 35 in week two, week one still has 5 overtime hours.
How do I calculate overtime if I am paid a fixed salary?
The Department of Labor gives this example: a fixed salary of $405 for a regular 45-hour week gives a regular rate of $405 ÷ 45 = $9.00. The employee is then owed an additional half the regular rate for each overtime hour: 5 × $4.50 = $22.50. Whether you are entitled to overtime depends on whether you are exempt, which this calculator cannot decide.
Does this calculator include state overtime rules or taxes?
No. It uses the weekly limit and multiplier you set (40 hours and 1.5 by default). Some states and employers count overtime by the day or pay double time; you can pick a different multiplier here and add a daily limit under More options on the time card page. Tax is only a flat percentage you type yourself.
Do bonuses change my overtime rate?
They can. The DOL explains that the regular rate includes all pay for employment except certain payments listed in the law, such as discretionary bonuses and pay for expenses. This calculator simply uses the hourly rate you enter.
