CalcKitOvertime Pay Calculator
Your hours
The 1.5× overtime rate is the federal standard under the Fair Labor Standards Act (FLSA): non-exempt workers get at least time and a half for hours over 40 in a workweek. Some states, jobs and union contracts pay more — California, for example, requires double time after 12 hours in a day. This calculator shows gross pay only, before taxes and deductions.
Example: $20 an hour, 40 regular hours + 10 overtime hours at time and a half — regular pay is $800, the overtime rate is $30 an hour, overtime pay is $300, and total gross pay is $1,100 for the week. If every week were like this, annualised gross pay would be $57,200.
Behind the numbers
How overtime pay is calculated
Under the federal Fair Labor Standards Act, non-exempt employees earn at least time and a half — 1.5× their regular hourly rate — for every hour over 40 in a workweek. Regular pay is the regular hours × the hourly rate. Overtime pay is the overtime hours × the hourly rate × 1.5 (or 2× for double time). Total gross pay is regular pay + overtime pay. If you enter total hours instead, the first 40 count as regular and anything over 40 counts as overtime. The annualised figure multiplies the week’s gross pay by the number of weeks like this per year — it is an estimate, because most people do not work the same overtime every week.
$20 an hour, 40 regular hours + 10 overtime hours: regular pay = 40 × $20 = $800. Overtime rate = $20 × 1.5 = $30 an hour. Overtime pay = 10 × $30 = $300. Total gross pay = $800 + $300 = $1,100 for the week. Effective hourly rate = $1,100 ÷ 50 hours = $22.00 an hour. Annualised at 52 weeks like this: $1,100 × 52 = $57,200 a year.
Examples
Example weeks at time and a half (1.5×)
| Hourly rate | Regular + OT hours | Regular pay | Overtime pay | Total / week | Annualised |
|---|---|---|---|---|---|
| $15.00 | 40 + 5 | $600.00 | $112.50 | $712.50 | $37,050.00 |
| $20.00 | 40 + 10 | $800.00 | $300.00 | $1,100.00 | $57,200.00 |
| $25.00 | 40 + 10 | $1,000.00 | $375.00 | $1,375.00 | $71,500.00 |
| $30.00 | 40 + 15 | $1,200.00 | $675.00 | $1,875.00 | $97,500.00 |
| $20.00 | 40 + 20 | $800.00 | $600.00 | $1,400.00 | $72,800.00 |
All figures are gross pay, before taxes and deductions. At double time (2×), the $20-an-hour, 40 + 10-hour example is $800 regular + $400 overtime = $1,200 for the week.
Making overtime work for you
Ten overtime hours a week at $20 an hour adds $300 a week — $15,600 a year if it lasts all year — so a lower hourly rate with steady overtime can beat a higher rate with none.
Check whether you are exempt or non-exempt: salaried managers and some professionals are exempt from overtime under the FLSA, while most hourly workers are not.
Your state may pay more than the federal minimum: California requires double time after 12 hours in a day and after 8 hours on the seventh straight day of work.
Overtime is taxed like regular pay — there is no special overtime tax rate — but a bigger paycheck can push part of your income into a higher federal bracket for that year.

Frequently asked questions
How is overtime pay calculated?
Multiply your overtime hours by your hourly rate times 1.5, then add your regular pay. At $20 an hour with 40 regular hours and 10 overtime hours: regular pay is 40 × $20 = $800, the overtime rate is $30 an hour, overtime pay is 10 × $30 = $300, and total gross pay is $1,100 for the week.
What is time and a half?
Time and a half means 1.5 times your regular hourly rate for overtime hours. At $20 an hour, time and a half is $30 an hour. It is the federal minimum overtime rate under the Fair Labor Standards Act for non-exempt workers on hours over 40 in a workweek.
Is overtime taxed differently?
No. Overtime pay is taxed at the same rates as regular pay — there is no special overtime tax. A bigger paycheck can mean more tax withheld that week, and overtime can push part of your annual income into a higher federal tax bracket, but the overtime itself is not taxed at a higher rate.
Do all workers get overtime pay?
No. The FLSA overtime rule covers non-exempt workers. Exempt workers — such as many salaried executives, administrators and professionals who meet the salary and duties tests — are not owed overtime by federal law, though their employer or state may still pay it. Some states also have stricter rules, such as daily overtime in California.
