About the Time and a Half Calculator
Time and a half means your normal hourly pay times 1.5, and this calculator turns that into the two numbers you actually want: your time-and-a-half rate per hour, and the overtime pay you earned for the extra hours. Type your rate and your overtime hours, and both appear right away. Most plain calculators stop there and hand you one figure. This one splits your overtime pay into the normal pay for those hours and the bonus half stacked on top, so you can see how much of your check is the actual time-and-a-half premium instead of guessing at it. And if you just want the rate for a common wage, tap one of the wage buttons and it fills in for you, so time and a half for $15 or $18 an hour takes a second.
Everything runs in your browser. No account, no upload, no cap on how often you use it. The result updates as you type, so you can try a few different overtime totals and watch the pay move. When you want to keep a result or send it to someone, the Share button copies a link that reopens the calculator with your exact numbers already in place.
How to use
- Enter your normal hourly rate. Use your standard base rate, for example 20 for $20 an hour, not a rate that already has overtime folded into it.
- Enter your overtime hours. These are only the hours paid at the time-and-a-half rate. A blank counts as zero, and you can use decimals like 6.5 for a partial hour.
- Read your results. The time-and-a-half rate per hour sits up top, and your overtime pay for those hours is the big number below it.
- Check the split. Under the total, the tool shows the normal pay for those hours and the time-and-a-half premium separately, so you can see the bonus on its own.
- Tap a common wage to fill the rate fast, or hit Share to copy a link with your figures baked in.
What time and a half actually means
Time and a half is your regular rate plus another half of it on top, which works out to multiplying by 1.5. The 1.5 comes straight from the words. One and a half is one whole plus one half, and a half written as a decimal is 0.5, so one and a half is 1.5. Multiply your rate by that and you get your normal pay (the one) plus half again (the and a half).
Take a rate of $20 and 6 overtime hours. First the rate: $20 times 1.5 is $30, so every overtime hour pays $30 rather than the usual $20. Then the pay: $30 times 6 hours is $180. That $180 is what you earned for those six overtime hours specifically, and it is separate from your pay for the rest of the week.
See the premium, not just a total
The premium is the part of your overtime pay that is genuinely extra, and this calculator shows it on its own line. In that $20 example, six hours at your normal rate would have paid $120. At time and a half the same six hours pay $180. The $60 gap is the premium, the reward the 1.5 multiplier is there to give you.
Seeing that number on its own is worth more than it sounds. When you are staring at a pay stub that looks a little light, the premium is exactly the piece that gets shorted, because payroll systems sometimes pay overtime hours at the flat rate and drop the half. Split out clearly, a wrong premium jumps out at you instead of hiding inside a total. It also makes a real difference when you are deciding whether to pick up a shift. The premium is the whole reason an extra day is worth more than a normal one, and having the dollar figure in front of you makes that call easier than doing it in your head after a long week.
A quick rate lookup for common wages
A lot of the time people are not building a paycheck at all. They just want to know what time and a half is on their wage. The buttons under the calculator cover the wages folks look up most, and each one fills the rate with a single tap. Here is what a few of them come to.
| Normal rate | Time-and-a-half rate | Extra per hour |
|---|---|---|
| $15.00 | $22.50 | $7.50 |
| $18.00 | $27.00 | $9.00 |
| $20.00 | $30.00 | $10.00 |
| $25.00 | $37.50 | $12.50 |
| $30.00 | $45.00 | $15.00 |
The pattern holds for any wage. The time-and-a-half rate is always the base plus half, and the extra per hour is always half your normal rate. So on $16 an hour, the premium is $8 an hour, and time and a half is $24.
Which hours actually count
The math of time and a half is the same everywhere. Which hours qualify for it is not, and that part trips people up. In the United States, federal law under the Fair Labor Standards Act requires time and a half for most hourly workers on hours past 40 in a single workweek, and a number of states go further than that. California, for one, starts daily overtime after 8 hours in a day. And salaried employees who are classified as exempt often get no overtime at all, whatever their hours run to.
So this tool does the rate and the premium, and it trusts you to put in hours that already qualify. If you want the whole picture, your regular hours and overtime and any double time added into one gross paycheck, with the 40-hour and California rules sorted out for you, use the overtime pay calculator instead. This page is for the time-and-a-half rate itself and the bonus it pays.
Frequently asked questions
How much is time and a half for $15 an hour?
It is $22.50 an hour. Fifteen dollars times 1.5 is 22.50, and the extra half is $7.50 an hour, so every overtime hour at that wage pays you $7.50 more than a normal one. Ten overtime hours at $15 would come to $225, of which $75 is the premium.
Is this different from an overtime pay calculator?
Yes, and on purpose. This tool is built around the time-and-a-half rate and the premium you earn, so it is fast for checking a wage or one bucket of overtime hours. The overtime pay calculator handles a full week, adding your regular pay, overtime, and double time into one gross paycheck and splitting the hours by federal or California rules. Use that one when you need the full check. Here, the focus is just the rate and the premium.
Does time and a half get taxed at a higher rate?
No, and this myth costs people sleep. Overtime is taxed as ordinary income, at the same rates as the rest of your pay. A big overtime check can have more withheld up front because withholding tables react to a larger single paycheck, but that is not a special overtime tax, and it evens out when you file your return.
What if my pay includes tips or commission?
Then your overtime rate can be higher than your base hourly wage. Federal rules base overtime on your regular rate, which can fold in nondiscretionary bonuses and commissions, so a tipped or commissioned worker sometimes has a regular rate above the posted hourly. Enter that fuller rate here if you know it, rather than only the base.
Can I use this for double time or holiday pay?
This calculator is set to the 1.5 multiplier. For double time, your rate is your normal pay times 2 instead, so you can work that portion out separately, or use the overtime pay calculator, which takes double-time hours directly.
Is anything I type saved or sent anywhere?
No. The rate and hours you enter stay in your browser and are used only to do the math on your screen. Nothing is uploaded, there is no sign-up, and the Share link only contains the numbers if you choose to copy and send it yourself.
