In summary: Overtime pay is regular pay plus extra hours at a higher rate: (rate × regular hours) + (rate × multiplier × overtime hours). At $20/hour with 40 regular and 10 overtime hours at 1.5×, total pay is $1,100.

How your overtime pay adds up

Overtime pay is your regular pay plus extra hours paid at a higher rate: Total = (rate × regular hours) + (rate × multiplier × overtime hours). At $20 an hour with 40 regular hours and 10 overtime hours at time-and-a-half (1.5×), that is $800 regular + $300 overtime (10 × $30) = $1,100 for the week. The most common multiplier has its own tool, the time and a half calculator.

How to use this calculator

Enter your hourly rate, your regular hours, your overtime hours, and the overtime multiplier (1.5 for time-and-a-half, 2 for double time). The result breaks your pay into regular and overtime portions and shows your overtime hourly rate, so you can check a paycheck or plan extra shifts.

Overtime pay at different multipliers

For 10 overtime hours at a $20 base rate, the multiplier makes a clear difference:

MultiplierOT rateOT pay (10 hrs)
1.0× (none)$20.00$200.00
1.5× (time and a half)$30.00$300.00
2.0× (double time)$40.00$400.00

When overtime applies

Under the U.S. Fair Labor Standards Act, non-exempt employees generally earn at least 1.5× their regular rate for hours worked beyond 40 in a workweek. Some states add daily overtime or double-time rules, and salaried-exempt roles may not qualify. Check your state and contract — this calculator works for any rate and multiplier you enter.

From a weekly figure to a yearly one

This shows gross pay for one period, before tax. To see what a steady wage adds up to over a year, use the annual income calculator; to turn a salary back into an hourly rate for comparison, use the salary to hourly calculator.

Frequently asked questions

How is overtime pay calculated?
Multiply your hourly rate by the overtime multiplier (usually 1.5) to get the overtime rate, then multiply by overtime hours. Add that to your regular pay for the total.
What is time and a half?
Time and a half means 1.5 times your normal hourly rate. At $20 an hour, time-and-a-half overtime pays $30 per overtime hour.
When do I get overtime in the US?
Federal law generally requires at least 1.5× pay for non-exempt employees working more than 40 hours in a workweek. Some states have additional daily or double-time rules.
Is overtime taxed more?
Overtime is taxed at the same rates as regular income, but a larger paycheck can push more of your pay into a higher withholding bracket for that period. Your annual tax depends on total income.
What is double time?
Double time is 2× your regular rate, sometimes required for holidays or very long shifts depending on state law or your contract. Enter 2 as the multiplier to calculate it.
