Formula
Practical considerations:
Employee scope: Include all employees who left (e.g., resignations, terminations) during the period, excluding temporary or contract staff unless specified.
Timeframe alignment: Calculate over a consistent period (e.g., monthly, quarterly, annual) based on HR reporting cycles.
Definition clarity: Ensure consistency in defining "average number of employees" (e.g., average of headcount at the start and end of the period) across reports.
Policy clarity: Document how leaves of absence, rehires, or partial periods are handled in the attrition rate calculation.

Worked Example
Metric | Value | Notes |
|---|---|---|
Start headcount (Jan 1) | 400 | Core full-time employees |
End headcount (Mar 31) | 420 | After hires/exits |
Employees who left | 30 | 20 voluntary, 10 involuntary |
Attrition % (average-base) | 7.3% | 30 ÷ ((400+420)/2) × 100 |
Notes:
Voluntary Attrition = 20 ÷ 410 × 100 = 4.9%
Involuntary Attrition = 10 ÷ 410 × 100 = 2.4%
Total Attrition = 7.3% for the quarter (~29% annualized).
