Estimate, not financial or tax advice. The result is only as good as the numbers you enter and the assumptions listed below the calculator. Rates, tax rules and lender terms change, so check big decisions with the official source or a licensed professional. See the disclaimer.
Example Calculation
Say you earn $20 an hour and work 45 hours in a week. The first 40 hours are regular hours: 40 x $20 = $800. The last 5 hours are overtime at time and a half, which is $30 an hour: 5 x $30 = $150. Your pay for the week is $950, an average of $21.11 for every hour you worked. Two weeks like that pay $1,900, and a year of them would pay $49,400 before tax.
Weekly pay at $20 an hour, by hours worked
Overtime is paid at time and a half after 40 hours.
| Hours worked | Regular pay (40 hours) | Overtime pay | Total for the week |
|---|---|---|---|
| 40 | $800 | $0 | $800 |
| 42 | $800 | $60 | $860 |
| 45 | $800 | $150 | $950 |
| 48 | $800 | $240 | $1,040 |
| 50 | $800 | $300 | $1,100 |
| 55 | $800 | $450 | $1,250 |
| 60 | $800 | $600 | $1,400 |
Overtime rate by hourly pay
The hourly rate you are paid for each overtime hour, at time and a half and at double time.
| Regular hourly pay | Time and a half (1.5x) | Double time (2x) |
|---|---|---|
| $12 | $18 | $24 |
| $15 | $22.50 | $30 |
| $18 | $27 | $36 |
| $20 | $30 | $40 |
| $25 | $37.50 | $50 |
| $30 | $45 | $60 |
| $40 | $60 | $80 |
How It Works
Federal law, the Fair Labor Standards Act, requires employers to pay covered, non-exempt employees at least one and a half times their regular rate for every hour over 40 in a workweek. A workweek is a fixed period of 168 hours, which is seven days in a row, and each week stands on its own. You cannot average a 30-hour week with a 50-hour week to avoid overtime.
The calculator takes your hourly pay and splits the hours you worked into regular hours and overtime hours. Regular hours are paid at your rate. Overtime hours are paid at your rate times the overtime rate you pick: 1.5 for time and a half, 2 for double time. If your job, your contract or your state starts overtime at a different number of hours, change the box called Overtime starts after.
If you also earn a bonus or shift pay that depends on hours, output or attendance, the law counts it in your regular rate, and overtime is based on that higher rate. Type the bonus for the week and the calculator works out the regular rate for you. A bonus that your employer gives entirely at its own choice does not count.
The result is before tax. Overtime is taxed like the rest of your wages, so use the paycheck calculator to see what reaches your bank account, or the hourly to salary calculator to see what a year of overtime adds.
Formula Explained
overtime hours = hours worked - hours before overtime starts, and never less than 0. regular hours = hours worked - overtime hours.
regular pay = hourly pay × regular hours and overtime pay = hourly pay × overtime rate × overtime hours. The total is the two added together, plus any bonus.
With a bonus or shift pay: regular rate = (hourly pay × all hours + bonus) ÷ all hours, and the extra owed on overtime is (overtime rate - 1) × regular rate × overtime hours.
Assumptions and limits
- Overtime is counted by the workweek, as the federal Fair Labor Standards Act does. Daily overtime rules are not built in: the questions above show how to enter them.
- The overtime rate and the hour where overtime starts are whatever you enter. Federal law sets 1.5 times the regular rate after 40 hours for covered, non-exempt employees, and state law, union contracts and employment agreements can set more.
- Only a bonus or shift pay that you type in is counted in the regular rate. Gifts, bonuses that are entirely at the employer's choice, expense payments and paid time off are not.
- Results are before tax and before deductions such as retirement contributions and health insurance.
- The yearly figure assumes the same week, 52 times, and the Every 2 weeks line doubles one week.
Frequently Asked Questions
How do I calculate overtime pay?
Pay regular hours at your regular rate and every hour over 40 in the week at 1.5 times the rate. At $20 an hour and 45 hours, that is 40 x $20 = $800 plus 5 x $30 = $150, so $950 for the week. Overtime is counted week by week, so for a two-week pay period work out each week on its own and add them.
How do I calculate time and a half?
Multiply your regular hourly rate by 1.5. At $16 an hour, time and a half is $24 an hour, and at $20 an hour it is $30. Double time is the rate times 2, which is $40 an hour at $20.
How much is overtime pay at $15, $20 or $25 an hour?
Time and a half is $22.50 an hour at $15, $30 at $20 and $37.50 at $25. Double time is $30, $40 and $50. Five overtime hours at time and a half add $112.50, $150 and $187.50 to the week.
How much is overtime pay at $18 an hour?
At $18 an hour, time and a half is $27.00 an hour ($18 x 1.5). Five overtime hours add $135.00 and ten overtime hours add $270.00 before tax. Double time would be $36.00 an hour.
How much is time and a half for $17 an hour?
Time and a half for $17 an hour is $25.50 an hour ($17 x 1.5). Five overtime hours pay $127.50 and ten pay $255.00 before tax. These are gross amounts, so federal tax, FICA and any state tax come out of them.
Does overtime start after 8 hours a day or 40 hours a week?
Federal law looks at 40 hours in a workweek, not at the day. Some states add a daily rule. If yours counts overtime by the day, add up the overtime hours for each day, enter your total hours for the week and set Overtime starts after to your regular hours. For example, 9 hours a day for four days plus 4 hours on the fifth is 40 hours, but with overtime after 8 hours a day there are 4 overtime hours, so you set the box to 36.
Which states have daily overtime rules?
California, Alaska and Nevada have overtime rules that start after 8 hours in a day (Nevada's applies to workers paid less than 1.5 times the state minimum wage), and Colorado's start after 12 hours in a day. California also requires double time after 12 hours in a day. In other states the federal 40-hour week is the rule for most workers, and a state can only add to it. Your state labor department can tell you the exact rule for your job.
What is the regular rate of pay?
It is what you earn for each hour worked once the pay for the week is counted: your hourly pay plus bonuses tied to hours, output or attendance and shift pay, divided by the hours worked. Overtime is based on it. Take a worker paid $20 an hour with a $50 attendance bonus for a 45-hour week. The regular rate is ($900 + $50) / 45 = $21.11, so the extra owed for 5 overtime hours at time and a half is 5 x 0.5 x $21.11 = $52.78. The week pays $900 + $50 + $52.78 = $1,002.78.
Do salaried employees get overtime?
Some do. A salaried employee who is not exempt, because the pay is below the legal salary level or the duties do not fit an exemption, is owed overtime for hours over 40. If you are unsure, ask your payroll team or your state labor agency whether your job is exempt.
Can I use this for a two-week pay period?
Overtime is worked out one week at a time, so enter each week on its own and add the totals. The Every 2 weeks line doubles one week, which is only right when both weeks are the same.
How is overtime taxed?
Overtime is wages. Federal income tax, Social Security and Medicare tax, and state tax are taken from it like the rest of your pay. A big overtime check can look more heavily taxed because payroll may assume the amount continues all year. Your real tax is worked out on your total income when you file. Use the paycheck calculator to see your take-home pay.
Can my employer give me time off instead of overtime pay?
Private employers generally cannot give comp time in place of overtime pay under federal law. Public agencies have some special rules. Ask your state labor agency if you are unsure.

Methodology and sources
Regular pay is the hourly rate times the regular hours, and overtime hours are paid at the overtime rate you enter. When a bonus or shift pay is entered, the regular rate is all straight-time pay for the week divided by all hours worked, and the extra owed on overtime hours is the overtime rate minus 1, times the regular rate, times the overtime hours. This follows the regular rate method in the Department of Labor fact sheet on overtime pay.
- Fact Sheet #23: Overtime pay requirements of the FLSA, U.S. Department of Labor
- Overtime pay, U.S. Department of Labor
