  2. Attrition Rate: Shows the attrition rate you provided as a percentage.
  3. Period: Indicates the selected time period (month, quarter, or year) for the attrition calculation.

Attrition Calculator Formula

The formula for calculating attrition rate during a specific period is as follows:

Attrition Rate = (Number of Employees Left) / (Total Number of Employees + Number of New Employees Hired) * 100

This formula calculates the attrition rate as a percentage by dividing the number of employees who left the organization during the specified period by the sum of the total number of employees and the number of new employees hired.

Illustrative Example

Let's consider an example to illustrate the usage of the Attrition Calculator. Suppose an organization has a total of 500 employees, an attrition rate of 10% per year, a yearly reporting period, and the start and end dates of the period are January 1, 2023, and December 31, 2023, respectively. Employees leave due to various reasons, and in this case, the selected reason is Lack of Growth Opportunities.

Upon inputting these values into the Attrition Calculator and clicking the Calculate Attrition Rate button, the results will be displayed as follows:

  • Total Number of Employees: 500
  • Attrition Rate: 10%
  • Period: Year
  • Start Date: January 1, 2023
  • End Date: December 31, 2023
  • Reason for Leaving: Lack of Growth Opportunities
  • Number of Employees Left: 50
  • Number of New Employees Hired: X (calculated based on the selected period assumption)
  • Attrition Rate During Period: Y% (calculated attrition rate during the selected period)
