Churn Rate

Churn Rate measures the percentage of customers, subscribers, users, or accounts that discontinue their relationship with an organization during a defined period. It is one of the most important indicators of customer retention, product satisfaction, and long-term business sustainability, particularly within subscription-based and recurring revenue business models.

Churn may occur for numerous reasons including dissatisfaction, stronger competitive alternatives, pricing changes, evolving customer needs, declining product relevance, poor customer experience, or broader market conditions. Measuring churn alone provides limited insight. Meaningful analysis requires understanding which customer segments are leaving, why they leave, when they leave, and whether those departures could have been prevented.

Organizations often distinguish between voluntary churn, where customers actively choose to leave, and involuntary churn, resulting from payment failures, contractual expiration, or administrative issues.
