What is Employee Churn Rate?

Employee churn rate, also known as employee turnover rate, is a metric that measures the percentage of employees who leave an organization over a specific period. A high churn rate can be a significant concern for businesses, indicating potential issues with employee satisfaction, management, company culture, or compensation. Understanding and monitoring your churn rate is crucial for retaining talent, reducing recruitment costs, and maintaining productivity.

How to Calculate Employee Churn Rate

The formula for calculating employee churn rate is as follows:

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

To calculate the "Number of Employees Who Left During Period," you can use the following logic with the provided inputs:

Number of Employees Who Left = (Number of Employees at Start of Period + Number of Employees Hired During Period) – Number of Employees at End of Period

And the "Average Number of Employees During Period" is calculated as:

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

By plugging these values into the churn rate formula, you get your organization's employee turnover percentage.

Example Calculation:

Let's say at the beginning of a quarter (3 months), your company had 100 employees. During that quarter, you hired 5 new employees and ended the quarter with 95 employees.

  • Employees at Start: 100
  • Employees at End: 95
  • Employees Hired: 5

First, calculate the number of employees who left:

Employees Who Left = (100 + 5) – 95 = 105 – 95 = 10 employees

Next, calculate the average number of employees during the quarter:

Average Employees = (100 + 95) / 2 = 195 / 2 = 97.5 employees

Finally, calculate the churn rate:

Churn Rate = (10 / 97.5) * 100 ≈ 10.26%

This means that approximately 10.26% of your workforce turned over during that quarter. Analyzing this rate and its trends can help you identify areas for improvement in employee retention strategies.

If the math yields negative, it suggests more were hired than the net reduction observed from the start. // For churn, we usually focus on the *departures*. If the net change is positive, we can't infer *departures* directly from this formula, // but rather how many *net* employees were added. // If the intent is strictly to count those who LEFT, and the formula yields negative, // it means the number of hires *exceeded* the difference between start and end employees, // implying that the number of people who left is zero or less than what would be needed to account for the end number with hires. // Let's set to 0 if negative, as we can't have negative departures. employeesWhoLeft = 0; } var averageEmployees = (employeesAtStart + employeesAtEnd) / 2; if (averageEmployees === 0) { resultDiv.innerHTML = "Cannot calculate churn rate when the average number of employees is zero."; return; } var churnRate = (employeesWhoLeft / averageEmployees) * 100; resultDiv.innerHTML = "Number of Employees Who Left During Period: " + employeesWhoLeft.toFixed(0) + "" + "Average Number of Employees During Period: " + averageEmployees.toFixed(2) + "" + "Employee Churn Rate: " + churnRate.toFixed(2) + "%"; }
