Attrition Rate

Also known as: Turnover Rate Separation Rate Churn Rate
Sub Metrics: Voluntary Attrition Rate Involuntary Attrition Rate Regrettable Attrition Rate Non-Regrettable Attrition Rate

Definition

The Attrition Rate measures the percentage of employees who leave an organization over a specific time period relative to the average number of employees during that period. It's a fundamental metric for understanding your workforce stability and the effectiveness of retention strategies.

In Deckata: Attrition Rate is automatically calculated from your HR systems and updated in real-time—no spreadsheets or manual work required.

How to Calculate

Attrition Rate

Formula
(Number of Separations in Time Period / Average Headcount in Time Period) × 100
Example
Separations: 15
Average Headcount: 500
Calculation: (15 / 500) × 100 = 3.0%
Result: 3.0%
Remember that the time period is crucial to interpreting the rate! A 10% Annual Attrition Rate is much less concerning than a 10% Monthly Turnover Rate.
