1. What is Annual Attrition Rate?

The Annual Attrition Rate measures the percentage of employees who leave an organization during a given year compared to the average number of employees during that period. It's a key HR metric for understanding employee turnover.

2. How Does the Calculator Work?

The calculator uses the annual attrition formula:

Where:

• \( \text{Leavers} \) — Number of employees who left during the period
• \( \text{Average Employees} \) — Average number of employees during the period

Explanation: The formula calculates what percentage of your workforce left during the measurement period.

3. Importance of Attrition Rate Calculation

Details: Tracking attrition helps organizations understand workforce stability, identify retention issues, and measure the effectiveness of HR policies. High attrition can indicate problems with job satisfaction, compensation, or company culture.

4. Using the Calculator

Tips: Enter the total number of employees who left during the period and the average number of employees during that same period. Both values must be positive numbers.
