What Is Attrition Rate?
Attrition rate is a key HR metric that measures the rate at which employees leave an organization over a given period of time. Unlike turnover, attrition often refers to natural departures — such as retirement, resignation, or role elimination — where positions are not immediately filled.
How to Calculate Attrition Rate
To calculate attrition rate, divide the number of employees who left during a period by the average number of employees during that same period, then multiply by 100. For example, if 10 employees left out of an average workforce of 200, your attrition rate is 5%.
Why Attrition Rate Matters
High attrition rates can be costly and disruptive. They signal potential issues with company culture, management, compensation, or career development opportunities. Tracking attrition helps HR leaders identify patterns and take proactive steps before they lose key talent.
Strategies to Reduce Attrition
Reducing attrition starts with understanding why employees leave. Exit interviews, pulse surveys, and engagement data are all valuable tools. From there, focus on improving onboarding, career development pathways, manager effectiveness, and work-life balance to create an environment where employees want to stay.
