/tʃɜːn reɪt/
Churn rate is the percentage of customers who stop using a product or service during a given period. High churn means a business must constantly replace lost customers just to stay still.

Everyday Example
If a subscription app has 1,000 customers and 50 cancel per month, its monthly churn rate is 5%. At that rate, it replaces its entire customer base every 20 months.
