Overtime pay calculator
Enter your hourly rate and hours to see regular pay, overtime at time-and-a-half, and total weekly pay.
How overtime pay is calculated
Under the federal Fair Labor Standards Act (FLSA), a non-exempt employee must be paid at least one and a half times the regular rate of pay for every hour worked over 40 in a single workweek. A workweek is a fixed, recurring block of 168 hours (seven 24-hour days) that your employer sets. Hours cannot be averaged across two weeks, so 30 hours one week and 50 the next still means 10 overtime hours in the second week.
The calculator uses this formula:
- Regular pay = hourly rate × regular hours (up to 40)
- Overtime pay = hourly rate × multiplier × overtime hours
- Total weekly pay = regular pay + overtime pay
Worked example
At $25 an hour, 40 regular hours pay $1,000. The overtime rate is $25 × 1.5 = $37.50, so 5 overtime hours add $188. Gross pay for the week is $1,188. These are gross figures: federal income tax, Social Security, Medicare and any state tax are withheld from the total, and overtime is taxed as ordinary wages.
| Hourly rate $15.00 | Overtime rate $22.50 |
| Hourly rate $20.00 | Overtime rate $30.00 |
| Hourly rate $25.00 | Overtime rate $37.50 |
| Hourly rate $30.00 | Overtime rate $45.00 |
What changes the result
The regular rate is not always your base rate. Non-discretionary bonuses, shift differentials and most incentive pay must be folded into the regular rate before the 1.5 multiplier is applied. The shift differential calculator does that blend for you.
Some states add daily overtime. California pays time and a half after 8 hours in a workday and double time after 12, and a few other states have their own daily rules. Use the double overtime calculator when daily rules apply.
Exempt employees do not earn overtime. Salaried workers who meet the federal duties and salary tests for the executive, administrative or professional exemptions are not covered by the overtime rule.

Common questions
How is overtime pay calculated?
Under the federal FLSA, non-exempt employees earn at least 1.5 times their regular hourly rate for hours over 40 in a workweek. Overtime pay = hourly rate × 1.5 × overtime hours. Some states such as California also require daily overtime, so check your state rules.
What is time-and-a-half?
Time-and-a-half means 1.5 times your regular hourly rate. At $25 per hour, your overtime rate is $37.50 per hour.
