Annual Attrition Equation:
| From: | To: |
The Annual Attrition Calculation Formula measures the rate at which employees leave an organization over a year, expressed as a percentage of the average workforce size during that period.
The calculator uses the Annual Attrition equation:
Where:
Explanation: The formula calculates the percentage of workforce that left the organization relative to the average workforce size during the measurement period.
Details: Tracking annual attrition helps organizations understand employee turnover patterns, assess retention strategies, and plan workforce needs. High attrition may indicate workplace issues, while very low attrition might suggest stagnation.
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 year_avg greater than zero.
Q1: What's a good annual attrition rate?
A: This varies by industry, but typically 10-15% is considered normal in many sectors. Rates above 20% may indicate problems.
Q2: How is year_avg calculated?
A: Year average is typically calculated as (beginning headcount + ending headcount)/2, or using monthly averages for more precision.
Q3: Should voluntary and involuntary exits be separated?
A: For deeper analysis, yes. Voluntary attrition (resignations) often indicates different issues than involuntary (terminations).
Q4: How does this differ from monthly attrition?
A: Monthly attrition looks at turnover within a month, while annual gives a bigger picture and smooths seasonal variations.
Q5: Should new hires be included in exits?
A: Typically no - exits refer to employees who left after being with the organization for some time. Very short-term hires may be excluded.
