Overtime pay calculator
Enter your hourly rate and the hours you worked in a week. The calculator splits them into regular and overtime hours and estimates your gross pay, using time and a half after 40 hours unless you change it.

How to use the overtime calculator
- Enter your hourly rate. Leave it blank if you only want the hours split.
- Enter the hours for the workweek. 45, 42.5 and 42:30 all work. Add another week to compare weeks; each is worked out separately.
- Check the rule. Overtime after 40 hours at 1.5× is filled in. Change either one if your job uses something else.
- Add double time if you get it. Set the weekly hours where double time starts and its multiplier.
Overtime formula
Regular hours = the smaller of hours worked and 40.
Overtime hours = hours worked − 40, or 0 if you worked 40 or less.
Gross pay = regular hours × rate + overtime hours × rate × 1.5.
With double time, the hours over the double-time threshold are taken out of overtime and paid at the double-time multiplier instead. Pay is worked out from the exact hours you enter and rounded to the cent at the end of each line.
Examples
46 hours at $22. 40 × $22 = $880 regular. 6 × $33 = $198 overtime. Total $1,078.
Two weeks of 50 and 30 hours at $20. Week one: 40 × $20 + 10 × $30 = $1,100. Week two: 30 × $20 = $600. Total $1,700. Averaging the two weeks to 40 each would wrongly give $1,600.
Double time. 64 hours at $20, overtime after 40 at 1.5× and double time after 60 at 2×: 40 × $20 = $800, 20 × $30 = $600 and 4 × $40 = $160, for $1,560.
What this estimate leaves out
Real overtime pay depends on things a quick calculator can't see. Bonuses, commissions and shift premiums can raise the regular rate that overtime is based on. State laws can add daily overtime, seventh-day rules and double time. Some jobs are exempt from overtime altogether.
Treat the result as an estimate of gross pay before tax, not as payroll or legal advice. If your pay stub disagrees, ask your employer how they calculate it or contact your state labor department.
Frequently asked questions
How is time and a half calculated?
Multiply your hourly rate by 1.5 for each overtime hour. At $20 an hour, overtime is $30 an hour, so 5 overtime hours add $150 on top of 40 regular hours at $800.
Is overtime based on the day or the week?
Under the US federal rule (the Fair Labor Standards Act), overtime is due for hours over 40 in a workweek, however they are spread across the days. Some states add daily rules: California, for example, also pays overtime after 8 hours in a day and double time after 12. This calculator does not apply state rules.
Can I average two weeks to avoid overtime?
Not under the federal rule. Each workweek stands on its own. 50 hours one week and 30 the next is 10 hours of overtime, even though the two weeks add up to 80.
Do paid holidays or sick days count toward the 40 hours?
Under the federal rule, overtime is based on hours actually worked, so paid time off usually doesn't count. Your employer, union contract or state may be more generous.
Does everyone get overtime?
No. Many salaried employees are exempt, depending on their duties and pay. This calculator assumes you are an hourly, non-exempt employee. Check with your employer or the US Department of Labor if you're not sure.
