How to use the Time and a Half Calculator
- Enter your regular hourly rate.
- Choose how to enter your hours: the total for the week (overtime starts after 40 hours unless you change it), or regular, time-and-a-half and double-time hours separately.
- Read your overtime rate, overtime pay and total pay for the week. The table shows what each extra overtime hour adds.
About this tool
Time and a half means one and a half times your normal hourly rate: at $20 an hour, each overtime hour pays $30. To work out a week’s pay, multiply your regular hours by your rate, multiply your overtime hours by 1.5 times your rate, and add the two. Forty regular hours at $20 plus 8 overtime hours at $30 is $800 + $240 = $1,040.
Another way to see it: every overtime hour is paid as 1.5 regular hours, so 8 hours of overtime count as 12 hours of pay. Double time works the same way with 2 instead of 1.5.
In the US, the Fair Labor Standards Act requires time and a half for non-exempt employees for every hour over 40 in a workweek. Some states go further: California, for example, also pays overtime after 8 hours in a day and double time after 12. Salaried exempt employees usually aren’t owed overtime, and contracts or union agreements can be more generous than the law. The figures here are gross pay; to see what is left after tax, use the take-home pay calculator. If you need to total clock-in and clock-out times first, start with the time card calculator.
Frequently asked questions
How do I calculate time and a half?
Multiply your hourly rate by 1.5. At $18 an hour, time and a half is $27. Then multiply that by your overtime hours: 6 hours of overtime pay $162.
What is time and a half for $20 an hour?
$30 an hour. Ten overtime hours at that rate add $300 to your pay.
When does overtime start?
Under US federal law, after 40 hours in a workweek for non-exempt employees. A few states, such as California, also count daily overtime. Set the threshold in the calculator to match your rule.
What is double time?
Twice your regular rate. It is not required by federal law, but some states (California after 12 hours in a day, for example), employers and union contracts pay it for long shifts or holidays.
Is overtime taxed more?
No. Overtime is taxed as ordinary wages. A bigger paycheck can have more withheld because payroll treats it as if you earned that much every period, but your actual tax is settled on your annual income.
Is overtime tax-free now?
Partly, for 2025 to 2028. A new federal deduction lets you deduct the premium part of overtime the FLSA requires (the extra half in time and a half, not the whole overtime pay) from taxable income: up to $12,500 a year, or $25,000 on a joint return, reduced above $150,000 of modified adjusted gross income ($300,000 joint). It is claimed on your tax return; Social Security, Medicare and usually state tax still apply. The calculator shows the premium part as its own figure. See the IRS’s guidance on the no tax on overtime deduction for the details.
Do paid holidays or sick days count toward overtime?
Under the federal rule, overtime is based on hours actually worked, so paid time off usually doesn’t count toward the 40 hours. Your employer or contract may count it anyway.
