Enter an hourly rate and hours above zero.
Hours up to the threshold pay at your normal rate, and the rest pay at the overtime rate. US federal rules generally start overtime after 40 hours a week. This shows gross pay before tax, and it isn't legal advice.
How do you calculate overtime pay?
Overtime pay splits your week into two buckets, so it's not as tricky as a paycheck makes it look. The hours up to the threshold, usually the first 40 in a week, pay at your normal hourly rate. Every hour past that pays at the overtime rate, which is your rate times a multiplier, most often 1.5 for time and a half. So you work out the regular pay, work out the overtime pay, and add them together for the gross weekly total. Say you earn $20 an hour and put in 48 hours: that's 40 hours at $20, which is $800, plus 8 hours at $30, which is $240, for $1,040. This tool runs every step, so you'll see the split and the total the moment you type your hours, and you don't have to reach for a paycheck stub to check the math.

Weekly pay by hours
Here's a rough guide at $20 an hour, overtime after 40 hours, at time and a half. It's a starting point, so don't treat it as exact, since your rate and rules won't match every job. When you're ready, run your own numbers above.
| Hours | OT hours | Weekly gross |
|---|---|---|
| 40 | 0 | $800 |
| 45 | 5 | $950 |
| 48 | 8 | $1,040 |
| 60 | 20 | $1,400 |
Frequently asked questions
You enter your hourly rate, the hours you worked, the weekly threshold where overtime starts, and the overtime multiplier, and it splits your pay for you. It pays the hours up to the threshold at your normal rate, then pays the rest at the higher overtime rate, and adds them into a weekly total. Everything runs in your browser, so you'll see the pay change as you adjust a number, and nothing you type leaves your device.
Overtime is your regular hourly rate multiplied by an overtime factor, usually 1.5, for every hour past the threshold. So you pay the first 40 hours at the normal rate, then the extra hours at time and a half. If you earn $20 an hour and work 48 hours, that's 40 hours at $20 plus 8 hours at $30, which comes to $1,040 for the week. The calculator runs that split the moment you type the hours.
Time and a half means your overtime rate is 1.5 times your normal hourly pay, so a $20 rate becomes $30 for each overtime hour. It's the most common overtime multiplier, and it's the default here. Some jobs pay double time, which is 2 times the rate, for holidays or very long weeks, so you can change the multiplier to 2 and the calculator updates the overtime rate and the total right away.
In the US, federal rules generally start overtime after 40 hours in a workweek for hourly employees, which is why the threshold defaults to 40. Some states and contracts use a daily threshold or different rules, so don't treat this as legal advice. You can set the threshold to match your own situation, and the calculator will pay everything above it at the overtime rate while everything below stays at your normal pay.
No, this shows your gross overtime pay before any deductions, so it doesn't take out income tax, Social Security, or benefits. Your take-home pay will be lower once those come off. Think of this as the pay your employer owes for the hours, which is handy for checking a paycheck or planning a big week. For after-tax numbers, you'd run the gross figure through a separate paycheck or take-home tool.
Yes, it's completely free, with no sign-up, and it runs right in your browser, so nothing you enter leaves your device. Type your rate and hours, set the threshold and multiplier, and read the pay in a tap. Bookmark it for checking a paycheck, planning extra shifts, or settling a question with payroll, and you'll have a clear overtime estimate whenever you need one.
