How this calculator works
Enter your regular hours, overtime hours, hourly rate, and overtime multiplier to calculate overtime pay and total gross pay. The default 1.5 multiplier matches the federal time-and-a-half rule for covered nonexempt employees working more than 40 hours in a week.
Worked example
An employee who works 40 regular hours and 5 overtime hours at $20 per hour with time-and-a-half overtime earns $150 in overtime pay and $950 in total pay, because 5 × $20 × 1.5 = $150 and $800 + $150 = $950.
Common mistakes
- Applying the overtime multiplier to all hours instead of only the overtime hours.
- Entering an overtime hourly rate as the regular rate and then applying the multiplier again, which double-counts the premium.
- Assuming federal rules everywhere: some states require daily overtime or a higher multiplier than time-and-a-half.
- Mixing pay periods, such as entering weekly hours with a biweekly salary-derived rate.
Frequently asked questions
How is overtime pay calculated?
Multiply overtime hours by the hourly rate and the overtime multiplier, then add regular pay. With time-and-a-half the math is (regular hours × rate) + (overtime hours × rate × 1.5). For 40 regular hours and 5 overtime hours at $20 per hour, that is (40 × $20) + (5 × $20 × 1.5) = $800 + $150 = $950.
What is time-and-a-half?
Time-and-a-half means 1.5 times the regular hourly rate. Under the federal Fair Labor Standards Act, covered nonexempt employees must be paid at least 1.5 times their regular rate for hours worked beyond 40 in a workweek.
How do I calculate overtime for a full week?
Add up regular hours (up to 40) and overtime hours (beyond 40), then enter the totals here with your hourly rate. If you track clock-in and clock-out times instead, use the Punch Clock Calculator to total the hours first, then bring the totals here.
Does overtime start after 8 hours in a day?
Under federal law, overtime starts after 40 hours in a week, not 8 in a day. Some states, such as California, require daily overtime after 8 hours. Check your state labor rules or set the hours and multiplier to match your employer policy.
What is double time?
Double time means 2 times the regular hourly rate. Some employers and states require it past a higher threshold, such as more than 12 hours in a day in California. Enter 2 as the overtime multiplier to calculate it here.
Is overtime pay taxed differently?
No. Overtime pay is taxed as ordinary wages, exactly like regular pay. A bigger paycheck can mean more withholding for that pay period, but there is no separate overtime tax rate.
