Employee Attrition Rate Calculator

Understand your organization's employee turnover by calculating your attrition rate. This metric helps identify potential issues with employee retention, company culture, or management practices.

What is Employee Attrition Rate?

Employee attrition rate, often referred to as employee turnover rate, is a metric used by organizations to measure the percentage of employees who leave the company over a specific period. A high attrition rate can be costly, leading to increased recruitment expenses, loss of productivity, and a negative impact on morale. Conversely, a low attrition rate generally indicates a stable and engaged workforce.

How to Calculate Attrition Rate

The formula for calculating attrition rate is as follows:

Attrition Rate = (Number of Employees Who Left During Period / Average Number of Employees During Period) * 100

To find the Average Number of Employees During Period, you can use this simpler, commonly accepted method for calculating attrition:

Average Number of Employees = (Number of Employees at Start of Period + Number of Employees at End of Period) / 2

In some contexts, if the number of employees leaving is readily available and you have the total number of employees at the start of the period, a simplified calculation can be used:

Attrition Rate = (Number of Employees Who Left During Period / Number of Employees at Start of Period) * 100

This calculator uses the latter, more direct method when the number of employees who left is provided. A lower attrition rate is generally desirable, suggesting good employee retention and satisfaction.

Example Calculation

Let's say your company started the quarter with 100 employees. By the end of the quarter, you had 95 employees. During that same quarter, 10 employees left the company.

  • Number of Employees at Start of Period: 100
  • Number of Employees Who Left During Period: 10

Using the simplified formula:

Attrition Rate = (10 / 100) * 100 = 10%

This means that 10% of your employees left the company during that quarter.
