Overtime Calculator
Calculate regular hours, overtime hours, overtime pay and total estimated earnings.
What Is an Overtime Calculator?
An Overtime Calculator helps you calculate regular working hours, overtime hours, overtime pay and total estimated earnings based on your hourly rate.
If you work more than your regular-hours threshold, the calculator separates your standard hours from your overtime hours and applies the overtime rate you select.
For example, if you work 50 hours and overtime begins after 40 hours, the calculator treats the first 40 hours as regular time and the remaining 10 hours as overtime.
You can use the ShiftCalco Overtime Calculator with common overtime multipliers such as time and a half (1.5×), double time (2×), or enter a custom overtime hourly rate.
How to Use the Overtime Calculator
To calculate your overtime hours and estimated pay, enter your work details into the calculator above.
- Enter your total hours worked.
- Enter the number of hours after which overtime begins.
- Enter your regular hourly rate.
- Select your overtime rate, such as 1.5× or 2×.
- Use the custom overtime rate option if you are paid a specific overtime hourly rate.
- Click Calculate Overtime.
The calculator will show your regular hours, overtime hours, regular pay, overtime hourly rate, overtime pay and total estimated earnings.
Overtime Calculation Example
Suppose you worked 50 hours, your normal hourly rate is €16, and overtime begins after 40 hours. Your overtime rate is time and a half, or 1.5×.
Your hours would be divided into:
- Regular Hours: 40 hours
- Overtime Hours: 10 hours
Your regular pay would be:
40 × €16 = €640
Your overtime hourly rate would be:
€16 × 1.5 = €24 per hour
Your overtime pay would be:
10 × €24 = €240
Your total estimated pay would therefore be:
€640 + €240 = €880
How Are Overtime Hours Calculated?
Overtime hours are calculated by subtracting your regular-hours threshold from your total hours worked.
The basic formula is:
Total Hours Worked − Regular Hours Threshold = Overtime Hours
For example, if you worked 47 hours and your overtime threshold is 40 hours:
47 − 40 = 7 overtime hours
If your total hours do not exceed the threshold you enter, the calculator will show zero overtime hours.
If you first need to calculate how many hours you worked during the week, use the Weekly Hours Calculator .
How Is Overtime Pay Calculated?
Overtime pay depends on your regular hourly rate, overtime multiplier and number of overtime hours.
First, calculate your overtime hourly rate:
Regular Hourly Rate × Overtime Multiplier = Overtime Hourly Rate
Then calculate your overtime earnings:
Overtime Hours × Overtime Hourly Rate = Overtime Pay
For example, if your regular rate is $20 per hour and your overtime rate is 1.5×:
$20 × 1.5 = $30 per overtime hour
If you work 5 overtime hours:
5 × $30 = $150 overtime pay
What Is Time and a Half?
Time and a half means an overtime rate equal to 1.5 times your regular hourly rate.
For example, if your normal hourly rate is $18:
$18 × 1.5 = $27 per hour
If a 1.5× overtime rate applies to your overtime hours, your calculated overtime rate would therefore be $27 per hour.
What Is Double Time?
Double time refers to a rate equal to 2 times your regular hourly rate.
For example, if your normal hourly rate is $20:
$20 × 2 = $40 per hour
If you worked 4 hours at a 2× rate, the estimated pay for those hours would be:
4 × $40 = $160
Common Overtime Rate Examples
The table below shows how different overtime multipliers affect an hourly rate of $20.
| Overtime Multiplier | $20 Regular Rate |
|---|---|
| 1.0× | $20.00/hour |
| 1.25× | $25.00/hour |
| 1.5× (Time and a Half) | $30.00/hour |
| 2× (Double Time) | $40.00/hour |
| 2.5× | $50.00/hour |
| 3× | $60.00/hour |
The multiplier you should use depends on the pay arrangement that applies to your work.
How to Calculate Total Pay With Overtime
Your total estimated pay combines your regular earnings and overtime earnings.
The formula is:
Regular Pay + Overtime Pay = Total Estimated Pay
For example:
- Regular Pay: $800
- Overtime Pay: $225
Your estimated total pay would be:
$800 + $225 = $1,025
The calculator above performs both calculations automatically.
What Is an Overtime Threshold?
An overtime threshold is the number of hours you enter before additional hours are treated as overtime for the calculation.
For example, if you enter a threshold of 40 hours and work 45 hours, the calculator will separate your time into 40 regular hours and 5 overtime hours.
Overtime thresholds are not the same everywhere. They may depend on local employment law, your employer, your contract, your industry or other workplace rules.
For this reason, ShiftCalco allows you to enter your own overtime threshold instead of assuming that the same threshold applies to everyone.
Custom Overtime Hourly Rate
Not every employee receives overtime using a simple multiplier of their regular hourly wage.
Your employment arrangement may specify a particular overtime hourly rate.
In that situation, select Use a custom overtime hourly rate instead and enter the amount you receive for each overtime hour.
The calculator will use your custom rate instead of multiplying your regular hourly rate.
Overtime Calculator for Different Currencies
ShiftCalco can be used with several currencies. Simply select the currency you use before entering your hourly rate.
The overtime calculation itself works the same way regardless of the currency selected. Your results will be displayed using the currency symbol you choose.

Frequently Asked Questions
How do I calculate overtime hours?
Subtract your regular-hours threshold from your total hours worked. For example, if you work 48 hours and overtime begins after 40 hours, you have 8 overtime hours.
How do I calculate overtime pay?
Multiply your regular hourly rate by your overtime multiplier to find your overtime hourly rate. Then multiply that rate by the number of overtime hours you worked.
What is 1.5 overtime?
A 1.5× overtime rate is commonly called time and a half. It means the calculated overtime hourly rate is 150% of the regular hourly rate.
What is double-time overtime?
Double time uses a 2× multiplier. For example, a $25 regular hourly rate becomes $50 per hour when calculated at a 2× rate.
How much is overtime for $20 an hour?
At a 1.5× overtime rate, $20 per hour becomes $30 per overtime hour. At a 2× rate, it becomes $40 per hour.
How much is overtime for $15 an hour?
At a 1.5× rate, a $15 regular hourly rate becomes $22.50 per overtime hour.
Can I change when overtime starts?
Yes. Enter your own overtime threshold into the calculator. This allows you to calculate overtime based on the threshold that applies to your situation.
Can I enter my own overtime rate?
Yes. You can select a standard overtime multiplier or use the custom overtime hourly rate option.
What happens if I work less than the overtime threshold?
The calculator will show zero overtime hours. All of your entered working hours will be calculated at your regular hourly rate.
Does this calculator determine whether I am legally entitled to overtime?
No. The calculator estimates hours and pay using the threshold and rates you enter. Whether overtime applies to you depends on the employment rules, contract and laws applicable to your situation.

About the Overtime Calculation
ShiftCalco's Overtime Calculator provides an estimate based entirely on the hours, overtime threshold, hourly rate and overtime rate you enter.
Actual overtime eligibility and pay can vary depending on your country, employment contract, employer policies, industry, working arrangements and applicable employment law.
The results should therefore be used as a general calculation and should not be treated as an official payroll statement or legal determination of overtime entitlement.
