## What attrition rate measures

Attrition (or turnover) rate is the percentage of employees who leave over a period. It's a core people metric — high attrition is expensive and disruptive, while tracking it reveals problems before they spread. The free [Attrition Rate Calculator](https://www.pyalm.com/free-tools/attrition-calculator) gives you the number and your retention rate.

## The formula

Attrition rate = employees who left ÷ average headcount × 100. If 8 people left from an average team of 100, attrition is 8% and retention is 92%.

## What's a good rate?

There's no universal benchmark — it varies by industry, role, and region. What matters most is the **trend**: a rising rate signals issues with pay, management, workload, or culture. Compare against your own history and sector norms.

## The hidden cost

Replacing an employee costs recruitment fees, onboarding time, lost productivity, and knowledge walking out the door. Reducing attrition often delivers a better return than almost any growth initiative.
