See the time and a half math, step by step
1. Time and a half rate = $20.00 × 1.5 = $30.00
2. Regular pay = $20.00 × 40 h = $800.00
3. Time and a half pay = $30.00 × 10 h = $300.00
4. Grand total = $800.00 + $300.00 + $0.00 + $0.00 = $1,100.00
How to Calculate Time and a Half
Working out time and a half by hand takes three short steps. The calculator above runs the same arithmetic live, so you can follow along and check every line.
- Find your time and a half rate. Multiply your regular hourly rate by 1.5. At $20 per hour, the time and a half rate is $20 × 1.5 = $30 per hour.
- Count your overtime hours. Under federal law that is usually every hour beyond 40 in one workweek. Pull the number straight from your time card.
- Multiply and add. Overtime pay = time and a half rate × overtime hours. Add regular pay to get the grand total for the week.
Worked example: you earn $18 per hour and put in 46 hours. Your time and a half rate is $27.00. Regular pay is $18 × 40 = $720.00, overtime pay is $27 × 6 = $162.00, and the week's grand total lands at $882.00.
What Is Time and a Half?
Time and a half is the overtime premium most hourly workers in the United States are owed: one and a half times the regular rate of pay for qualifying hours. The rule comes from the Fair Labor Standards Act (FLSA), which requires overtime at no less than 1.5× the regular rate after 40 hours in a workweek for non-exempt employees. Some states go further — California, for example, adds daily overtime after 8 hours in a day and double time after 12 — so it is worth checking your state labor office's rules as well.
People also earn time and a half through company policy: many employers offer it for weekends, holidays, or on-call shifts even when the law does not demand it. Whatever triggers the premium, the arithmetic is identical, and this time and a half calculator handles all of it — including double time and triple time lines when your employer pays 2× or 3×.
One habit worth keeping: check the time and a half line yourself before payday. Thirty seconds in a time and a half calculator with your rate and hours shows whether the paycheck matches the week you worked. Hour entry is still manual at many small businesses, and a missed hour of time and a half disappears quietly — running the time and a half math yourself is the cheapest audit there is.
Time and a Half Rates at Common Wages
A quick reference for the question everyone asks first — what is time and a half for my hourly rate? Each row shows the regular rate, the time and a half rate, and the double time rate.
| Regular rate | Time and a half (1.5×) | Double time (2×) |
|---|---|---|
| $12.00 | $18.00 | $24.00 |
| $15.00 | $22.50 | $30.00 |
| $18.00 | $27.00 | $36.00 |
| $20.00 | $30.00 | $40.00 |
| $25.00 | $37.50 | $50.00 |
| $30.00 | $45.00 | $60.00 |
For any other wage, type it into the calculator — the time and a half rate updates the moment you do, and you can override the multiplied rates if your contract uses different ones.

Time and a Half FAQ
How do you calculate time and a half?
Multiply your regular hourly rate by 1.5 to get the time and a half rate, then multiply that rate by your overtime hours. Add the result to your regular pay for the total. The calculator at the top of this page does all three steps as you type.
What is time and a half for $15.00 an hour?
$22.50 per hour. Fifteen dollars times 1.5 equals $22.50, so an overtime hour at $15 base pay is worth $22.50, and ten such hours add $225.00 to a paycheck.
What is 1.5 times the hourly rate?
It is the same thing as time and a half — the regular rate plus half of it again. A $24 rate becomes $36; a $19 rate becomes $28.50. Multiply by 1.5 or add 50%, the result is identical.
How do I calculate 1.5x overtime pay?
Take the overtime hours from your time card, multiply them by your time and a half rate, and you have the overtime line of your paycheck. If your hours are in hours-and-minutes form, convert them with the time to decimal calculator first so the multiplication is exact.
Is time and a half required on holidays?
Not by federal law — the FLSA only requires overtime after 40 hours in a workweek, whatever day those hours fall on. Holiday time and a half is a common employer policy rather than a legal rule, so check your handbook or contract.
Does time and a half apply to salaried employees?
Sometimes. Salaried workers classified as non-exempt still earn overtime; the weekly salary is converted to an hourly equivalent and hours past 40 are paid at time and a half of that rate. Exempt employees — most salaried professional, executive, and administrative roles above the salary threshold — are not owed overtime.
