Churn Rate vs Retention Rate: How to Read Both

Churn rate measures the share of customers lost in a period. Retention rate measures the share kept. They are connected, but each makes a different problem easier to see.

Use the Churn Rate Calculator and Retention Rate Calculator when reviewing subscriptions, memberships, repeat customers or user cohorts.

Churn highlights leakage

Churn is useful when you need to see how much of the customer base is leaving. It makes losses visible and helps prioritize fixes.

Retention highlights durability

Retention is useful when you need to show how much of the base remains active. It is often easier to communicate in growth and product reviews.

Keep the period consistent

Monthly churn and annual retention cannot be compared directly without conversion. Always label the time period and the customer group being measured.
