Overtime calculator
Enter your hourly rate, the hours you worked in the week and where overtime starts to see your pay. Time and a half is a multiplier of 1.5 and double time is 2.
This answer is for the example values in the boxes above. $20 an hour, 46 hours worked, overtime after 40 hours at 1.5 times the rate. Change the boxes to see your own answer.
The pay is before tax. Whether and how overtime is owed depends on your job, your state and your contract.
How it works
The calculator pays the hours up to the line where overtime starts at your hourly rate. It pays the hours past the line at your rate times the multiplier, which is 1.5 for time and a half. The two added together are the pay for the week.
It also shows the average you earn for each hour worked. That average is higher than your rate once overtime is in it.
Enter the hours of one workweek. Overtime is counted week by week, so do not add two weeks together.
A worked example
You earn $20 an hour and work 46 hours in the week, with overtime after 40. The 40 regular hours pay $800. The 6 overtime hours are paid at $30 an hour, which is $180. The week comes to $980, an average of $21.30 for each hour you worked.
What the federal law says
The Fair Labor Standards Act draws a line at 40 hours in a workweek. An employer it covers must pay at least one and one-half times the regular rate for the hours over that line. The workweek is a fixed period of 168 hours that can begin on any day and at any hour.
Some employees are exempt, including those in a bona fide executive, administrative or professional job. A state or city can set a shorter workweek, and the federal law does not excuse an employer from it.
What it leaves out
The pay is before tax, so it is not your take-home pay. The calculator uses the hourly rate you enter. The law defines the regular rate as all pay for the work, with a list of exceptions that includes gifts, so a promised bonus can raise it above your base wage. Ask your payroll office if you are not sure what yours is.

Questions
How do I calculate overtime pay?
Pay the hours up to the line at your hourly rate, and the hours over it at your rate times the multiplier. At $20 an hour with 40 regular hours and 6 overtime hours at time and a half, the pay is $800 plus $180, which is $980.
What is time and a half?
It is one and a half times your regular hourly rate for each overtime hour. At $20 an hour that is $30 an hour.
Does the law require time and a half after 40 hours?
The federal Fair Labor Standards Act sets overtime at not less than one and one-half times the regular rate for hours over 40 in a workweek, for the employees it covers. Some workers are exempt, and a state may set rules of its own.
Does double time come from the federal law?
No. The federal rule asks for at least one and one-half times the regular rate. Double time can come from a state law, a contract or your employer’s policy, so check which applies to you.
Who is exempt from overtime?
The federal law exempts employees in a bona fide executive, administrative or professional job, and outside salespeople, as the Secretary of Labor’s regulations define those terms.
What counts as a workweek?
A workweek is a fixed and regularly recurring period of 168 hours, which is seven days of 24 hours. It can start on any day and at any hour, and it need not match the calendar week.
