Overtime Pay Calculator

Overtime pay is the higher rate your employer must pay for hours worked beyond the standard 40 hour workweek. Under the Fair Labor Standards Act (FLSA), covered non-exempt employees must be paid at least 1.5 times their regular rate, known as time and a half, for every hour over 40 in a workweek. Some employers and some states go further: double time (2×) for holidays or very long days, and daily overtime after 8 hours in states like California. The calculator above is an overtime hours calculator and a pay calculator in one: it splits your week into regular hours and overtime hours and prices each part correctly.

One point that confuses many people: overtime is calculated per workweek, not per pay period. Eighty hours across two weeks with no week over 40 earns no federal overtime, while a single 50 hour week earns 10 overtime hours, even if the next week is short.

The overtime pay calculation has three steps, and it is the same whether you use this calculator or a pencil:

1. Find your overtime rate. Regular hourly rate × 1.5 (or × 2 for double time). At $20 an hour, time and a half is $30 an hour.
2. Price each block of hours. Regular hours × regular rate, plus overtime hours × overtime rate.
3. Add, then tax. The two blocks together are your gross pay. Tax is withheld from that total, which is why this is an overtime pay calculator with taxes, not just a gross pay tool.

Worked example. You earn $20 an hour and work 50 hours this week: 40 regular hours and 10 overtime hours. Regular pay is 40 × $20 = $800. Overtime pay is 10 × $30 = $300. Gross pay is $1,100. At an estimated 22% tax rate, about $242 is withheld and at a flat 22% estimate you take home about $858. So if you have ever asked what overtime pay is for $20 an hour, the answer is $30 an hour at time and a half, and $300 for a typical 10 hour overtime week.

A quick rate table for common wages, at time and a half: $15 an hour becomes $22.50, $18 becomes $27, $20 becomes $30, $25 becomes $37.50, and $30 becomes $45. Double time is simpler still: just double the rate.

A salary overtime calculator works slightly differently, because there is no hourly rate on your payslip. For a non-exempt salaried employee, your regular rate is your weekly salary divided by the hours that salary is meant to cover. A $52,000 salary on a 40 hour week is $1,000 a week, a $25 regular rate, and a $37.50 overtime rate. Choose "Annual salary" in the calculator above and it does this salary calculator overtime math for you automatically.

The big exception is exempt employees. Executives, administrators and professionals who pass the FLSA duties tests and earn above the salary threshold are exempt, which means no overtime pay is owed to them at all, however long the week runs. If you are not sure which side of that line you sit on, your job duties matter more than your job title.

This page answers the pay question: how much overtime will I earn, and what lands in my bank after withholding? Overtime pay is taxed as ordinary income at your normal rates; there is no special overtime tax rate, even though a large overtime paycheck is sometimes withheld as if that were your pay all year, which can make the tax look heavier than it really is.

The tax question is different: for 2025 to 2028, the premium part of your overtime can be deducted on your federal return, which is a separate calculation with a $12,500 or $25,000 cap. That is what our deductible overtime calculator, the No Tax on Overtime Calculator, is for, and the deduction itself is claimed on Schedule 1-A. Use this page during the year to check your pay, and that page at tax time to check your deduction.
