Overtime Pay Calculator
Calculate overtime pay for a workweek: regular pay, time-and-a-half or double-time hours, total weekly pay and your effective hourly rate.
Under the US Fair Labor Standards Act (FLSA), non-exempt employees must be paid at least one and a half times their regular rate for every hour over 40 in a workweek. This calculator splits a week's hours into regular, overtime and optional double-time hours, then shows the pay for each, your total for the week and your effective hourly rate. Use it to check a paycheck or to see what extra shifts are worth.
How to use this tool
- Enter your regular hourly rate.
- Enter the total hours you worked in the workweek.
- Keep the threshold at 40 hours unless your contract or state uses a different rule.
- Choose the overtime rate, and enter any double-time hours (already included in the total) if your state or employer pays them.
Formula
Pay = rate × regular hours + rate × multiplier × overtime hours + rate × 2 × double-time hours
Double-time hours are taken out of the total first. Regular hours are the remaining hours up to the threshold, and overtime hours are whatever is left above it.
Example
At $20 an hour and 46 hours in a week, the first 40 hours pay $800. The 6 overtime hours are paid at $30 (1.5 × $20), adding $180, so the week pays $980. Your effective rate is $21.30 an hour, and $60 of the overtime is premium above straight-time pay.
Frequently asked questions
Is overtime counted per day or per week?
Federal law uses the workweek — a fixed, recurring period of 168 hours — and hours cannot be averaged over two or more weeks. Some states add daily rules; California, for example, requires overtime after 8 hours in a day and double time after 12.
What is the "regular rate"?
Under the FLSA the regular rate includes nearly all pay for the work, such as shift differentials and non-discretionary bonuses, not just the base wage. If you earn these, your true overtime rate can be higher than 1.5 × your base rate.
Is overtime pay tax-free now?
For tax years 2025 through 2028, eligible workers can deduct the premium part of FLSA-required overtime (the "half" in time-and-a-half) from federal taxable income, up to $12,500 a year ($25,000 on a joint return), phasing out above $150,000 of modified adjusted gross income ($300,000 joint). Social Security and Medicare taxes still apply.
