Annual Attrition Rate Formula:
| From: | To: |
The Annual Attrition Rate Percentage measures the rate at which employees leave an organization over a year compared to the average number of employees during that period. It's a key HR metric for understanding workforce stability.
The calculator uses the annual attrition rate formula:
Where:
Explanation: The formula calculates what percentage of your average workforce left during the year, providing a standardized measure of turnover.
Details: Tracking attrition helps organizations understand workforce trends, identify potential problems in employee retention, and measure the effectiveness of HR strategies. High attrition can indicate issues with job satisfaction, compensation, or company culture.
Tips: Enter the total number of employees who left during the year and the average number of employees during that year. Both values must be positive numbers, with the average employees greater than zero.
Q1: What's considered a "good" attrition rate?
A: This varies by industry, but typically 10-15% is average. Rates below 10% are excellent for most industries, while rates above 20% may indicate problems.
Q2: How is "Year Average" calculated?
A: Average is typically calculated as (beginning employees + ending employees)/2, or more precisely as monthly averages summed and divided by 12.
Q3: Should voluntary and involuntary separations be combined?
A: It depends on your analysis purpose. For overall attrition, combine them. For retention analysis, you might track voluntary separations separately.
Q4: How often should attrition be calculated?
A: Annually is standard, but quarterly calculation can help identify trends earlier. Monthly may be too volatile for meaningful analysis.
Q5: Does this include temporary or contract workers?
A: Typically no - attrition rate usually refers to permanent employees. However, some organizations track contingent worker turnover separately.
