Employee Stability Index Calculator

The Employee Stability Index (ESI) measures the percentage of employees who have stayed with an organization for more than one year, reflecting workforce stability and employee retention.

Historical Background

In human resource management, understanding employee retention has always been critical for businesses. As organizations strive to create long-term value, retaining skilled employees becomes essential. The concept of measuring employee stability arose as a way to gauge the effectiveness of HR practices and ensure organizational continuity.

Calculation Formula

The formula to calculate the Employee Stability Index (ESI) is:

\[ \text{ESI} = \left( \frac{\text{Number of Employees with Over 1 Year of Service at End of Period}}{\text{Number of Employees at the Start of the Period}} \right) \times 100 \]

Example Calculation

If a company starts the year with 200 employees and 150 of them remain employed for over one year, the ESI would be:

\[ \text{ESI} = \left( \frac{150}{200} \right) \times 100 = 75\% \]

This means 75% of employees have stayed with the company for more than a year, indicating good employee retention.
