This calculator shows gross pay only, before income tax, Social Security, Medicare and any other deductions. It does not determine whether you are legally entitled to overtime, which depends on your role, hours and local labor law. Overtime rules vary by country, state and employer agreement. The result is an estimate, not legal or financial advice, so confirm your entitlement and final figures with your employer, your pay stub or a qualified adviser.

This overtime pay calculator works out how much extra you earn for hours beyond your regular schedule. Enter your hourly rate, the regular hours you worked, the overtime hours, and the overtime multiplier (1.5 for time and a half, 2 for double time). You will instantly see your regular pay, your overtime pay, and the gross total, with a clear breakdown of the overtime rate so you can check your paycheck with confidence.
What is the Overtime Pay Calculator?
Overtime pay is the higher rate you earn for hours worked beyond a set threshold, most commonly more than 40 hours in a workweek. Instead of your normal hourly rate, those extra hours are paid at a premium set by a multiplier. The most familiar multiplier is 1.5, known as 'time and a half', which means each overtime hour pays one and a half times your regular rate. Some situations, such as holidays or hours beyond a second threshold, are paid at 'double time', a multiplier of 2.
The math is straightforward once you separate the two buckets. Your regular pay is simply your hourly rate multiplied by your regular hours. Your overtime pay is your hourly rate multiplied by the overtime multiplier, which gives the overtime rate, then multiplied by the number of overtime hours. Adding the two together gives your gross pay for the period. For example, at $20 per hour with 40 regular hours and 10 overtime hours at 1.5x, your overtime rate is $30 per hour, so overtime pay is $300, regular pay is $800, and the gross total is $1,100.
Everything this tool reports is gross, meaning it is before any tax or deductions are taken out. Your actual take-home pay will be lower once federal and state income tax, Social Security, Medicare and any benefit contributions are withheld. The calculator is for estimating earnings and checking that your overtime has been counted and paid at the correct rate, not for working out net pay. Whether you qualify for overtime at all is a separate legal question that depends on your job classification and the labor laws where you work.
When to use it
- Checking that a paycheck paid your overtime hours at the correct time and a half or double time rate.
- Estimating how much extra you will earn before agreeing to pick up additional shifts or hours.
- Comparing the value of overtime at 1.5x versus double time when deciding which shifts to take.
- Helping a small business owner sanity-check payroll for hourly staff before running it.

Formula & method
Worked examples
You earn $20/hr, work 40 regular hours and 10 overtime hours at time and a half (1.5x).
- Regular pay = 20 x 40 = $800.00
- Overtime rate = 20 x 1.5 = $30.00 per hour
- Overtime pay = 30 x 10 = $300.00
- Gross total = 800 + 300 = $1,100.00
Result: Regular $800.00, overtime $300.00, gross total $1,100.00 (before tax)
You earn $18/hr, work 40 regular hours and 12 overtime hours at double time (2x).
- Regular pay = 18 x 40 = $720.00
- Overtime rate = 18 x 2 = $36.00 per hour
- Overtime pay = 36 x 12 = $432.00
- Gross total = 720 + 432 = $1,152.00
Result: Regular $720.00, overtime $432.00, gross total $1,152.00 (before tax)
Overtime pay at $25/hr with 40 regular hours, time and a half (1.5x), overtime rate $37.50/hr
| Overtime hours | Regular pay | Overtime pay | Gross total |
|---|---|---|---|
| 0 hrs | $1,000.00 | $0.00 | $1,000.00 |
| 5 hrs | $1,000.00 | $187.50 | $1,187.50 |
| 10 hrs | $1,000.00 | $375.00 | $1,375.00 |
| 15 hrs | $1,000.00 | $562.50 | $1,562.50 |
| 20 hrs | $1,000.00 | $750.00 | $1,750.00 |
Common overtime multipliers and what they mean
| Name | Multiplier | Overtime rate on $20/hr |
|---|---|---|
| Time and a half | 1.5x | $30.00 per hour |
| Double time | 2x | $40.00 per hour |
| Triple time (rare) | 3x | $60.00 per hour |
Common mistakes to avoid
- Treating gross overtime pay as take-home pay. The total shown here is gross, before tax and deductions. Overtime can push some income into a higher withholding bracket, so the extra you actually keep is less than the gross figure. Check your net pay on your pay stub.
- Applying the multiplier to total hours instead of overtime hours. Only the overtime hours get the higher rate. Your first set of hours (usually up to 40 in a week) is paid at the normal rate. Multiplying every hour by 1.5 overstates the pay considerably.
- Assuming all hours over 40 always qualify for overtime. Overtime eligibility depends on your job classification and local labor law. Some salaried or exempt roles are not entitled to overtime at all, so confirm your status before counting on extra pay.
- Confusing time and a half with double time. Time and a half is a 1.5x multiplier and double time is 2x. Using the wrong multiplier changes the overtime pay by a third or more, so set the correct one for your situation.

Frequently asked questions
How is overtime pay calculated?
Multiply your hourly rate by the overtime multiplier to get the overtime rate, then multiply that by your overtime hours. For time and a half at $20/hr, the overtime rate is $30/hr, so 10 overtime hours pay $300. Add this to your regular pay (rate x regular hours) for the gross total.
What is time and a half?
Time and a half means each overtime hour is paid at 1.5 times your regular hourly rate. If you earn $20 per hour, your time and a half rate is $30 per hour. It is the most common overtime rate for hours worked beyond the standard threshold.
What is double time?
Double time is overtime paid at 2 times your regular rate. At $20 per hour that is $40 per hour. It is less common than time and a half and is often used for holidays, or for hours worked beyond a higher second threshold, depending on your employer and local law.
Is the result before or after tax?
The result is gross pay, before any tax or deductions. Your take-home pay will be lower once federal and state income tax, Social Security, Medicare and any benefit contributions are withheld. Use this tool to estimate earnings and check your overtime rate, not to work out net pay.
Do I get overtime for working more than 40 hours?
Often, but not always. Many hourly employees earn overtime for hours over 40 in a workweek, but eligibility depends on your job classification and the labor laws where you work. Some salaried or exempt roles are not entitled to overtime, so confirm your status with your employer.
How do I work out my overtime hourly rate?
Multiply your regular hourly rate by the overtime multiplier. For time and a half, multiply by 1.5; for double time, multiply by 2. So a $22 per hour rate becomes $33 at time and a half, or $44 at double time. This calculator shows the overtime rate in the breakdown.
