How to Use the Overtime Calculator

Using this overtime calculator couldn't be easier. Start by setting up the hourly pay rates, the number of hours worked during the period, setup the multiplier and the overtime hours in this pay period, and you are ready to go. 

To get started you don’t need to download an Excel sheet or application. You can do the math directly on this page following these simple four steps:

  1. In the form below, start by filling the four cells below;
  2. Provide the amount in $ that you are paying per hour for your employees
  3. The second cell is about the regular hours worked for the defined period
  4. Define the overtime multiplier rate (known as OT rate). This is usually 1.5.

In this time you will have an easier time finding the paycheck details of your employees when you have overtime hours worked.

Note: The calculator assumes that employees are nonexempt.


Overtime Formula

The basic overtime formula is Hourly Rate x Overtime Multiplier × Number of Overtime Hours worked in a particular week.

To calculate the overtime rate, we are using the following inputs:

  • Regular Pay per Period (RP) = Regular Hourly Pay Rate × Standard number of hours;
  • Overtime Pay Rate (OTP) = Regular Hourly Pay Rate × Overtime Multiplier;
  • Overtime Pay per Period (OP) = OTP × Overtime Hours per Pay Period;
  • Total pay rate per period (TP) = RP + OP.


How to calculate overtime?

In this example, we are looking for a staff member who works 45 hours in a work period, where 40 hours are regular and five hours of overtime

To comply with the Department of Labor, Fair Labor Standards Act (FLSA), and for employees that work more than 40 hours, they must receive 1.5 times the rate of regular pay.

Total pay rate per period = (40 hours x $10) + (5 hours x 1.5 OT Multiple x $10) = $400 + $75 = $475 

In this way, you will be able to calculate the hourly overtime salary pay.
