Multiply a base hourly rate by 1.5 to estimate a time-and-a-half rate. Add the qualifying hours to see the gross pay for those hours. The calculator does not decide which hours qualify.

Pay estimate only. Your applicable overtime rule determines which hours qualify.
The formula
Time-and-a-half hourly rate = base hourly rate × 1.5. Pay for the qualifying hours = time-and-a-half rate × the hours entered. At $25 per hour, the premium rate is $37.50. Six hours at that rate produce $225 before deductions.
If all you need is the extra premium above straight-time pay that has already been included in a salary or paycheck, multiplying the base rate by 0.5 yields that incremental amount per qualifying hour. This tool displays the full 1.5× amount, so adding it to straight-time pay for those same hours would double count the base pay.
When is time and a half due?
For most covered, nonexempt employees, federal law requires at least 1.5 times the regular rate for hours actually worked over 40 in a fixed workweek. A weekend, holiday or late shift does not by itself trigger federal overtime. An employer policy, contract or state law may give additional premium pay.
What is the “regular rate”?
The regular rate may differ from the stated base hourly wage. Certain bonuses, commissions and pay for different kinds of work can matter. With more than one rate or additional compensation, use this tool for a rough estimate and review the actual regular-rate calculation.
Frequently asked questions
What is time and a half for $20 per hour?
$20 × 1.5 = $30 per qualifying hour. Five such hours would be $150 gross.
Is 1.5× the same as adding 50%?
Yes. One full base rate plus another half of that rate equals 1.5 times the base rate.
Does a holiday automatically mean time and a half?
Federal law does not generally require a premium simply because work occurs on a holiday. Check your employer policy and applicable state law.
