Understanding Employee Turnover Rate

Employee turnover rate is a key metric that measures how frequently employees leave an organization over a specific period. It's a crucial indicator of employee satisfaction, company culture, and the effectiveness of your HR strategies. A high turnover rate can be costly, leading to increased recruitment expenses, lost productivity, and decreased morale. Conversely, a very low turnover rate might indicate a lack of fresh talent or opportunities for advancement.

How to Calculate Employee Turnover Rate

The formula for calculating employee turnover rate is straightforward. You need three pieces of information:

  1. The number of employees at the beginning of the period.
  2. The number of employees at the end of the period.
  3. The number of employees who left the company during that same period.
The standard formula is:

Turnover 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 sum the number of employees at the start and end of the period and divide by two:

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

This calculator helps you quickly compute your organization's turnover rate. Understanding this metric allows businesses to identify potential issues and implement strategies to improve employee retention.

Example Calculation:

Let's say at the beginning of a quarter, your company had 100 employees. By the end of the quarter, you had 110 employees. During that same quarter, 15 employees left the company.

  • Number of Employees at Start = 100
  • Number of Employees at End = 110
  • Number of Employees Who Left = 15

First, calculate the average number of employees: (100 + 110) / 2 = 105

Then, calculate the turnover rate: (15 / 105) * 100 = 14.29%

So, the employee turnover rate for that quarter is approximately 14.29%.

function calculateTurnoverRate() { var startEmployees = parseFloat(document.getElementById("numberOfEmployeesAtStart").value); var endEmployees = parseFloat(document.getElementById("numberOfEmployeesAtEnd").value); var employeesLeft = parseFloat(document.getElementById("numberOfEmployeesWhoLeft").value); var resultDiv = document.getElementById("result"); // Validate inputs if (isNaN(startEmployees) || isNaN(endEmployees) || isNaN(employeesLeft) || startEmployees < 0 || endEmployees < 0 || employeesLeft startEmployees && employeesLeft > endEmployees) { resultDiv.innerHTML = "Number of employees who left cannot be more than the total number of employees at any point."; return; } var averageEmployees = (startEmployees + endEmployees) / 2; var turnoverRate = 0; if (averageEmployees > 0) { turnoverRate = (employeesLeft / averageEmployees) * 100; } else if (employeesLeft === 0) { turnoverRate = 0; // No employees and no one left, rate is 0 } else { resultDiv.innerHTML = "Cannot calculate turnover rate with zero average employees if someone left."; return; } resultDiv.innerHTML = "

Your Employee Turnover Rate is:
