### Churn Rate

Business
The percentage of customers who stop using a product or service over a given period.

Churn rate is a critical business metric that measures customer retention. It's calculated as the number of customers lost divided by the total number of customers at the start of the period. High churn rates indicate problems with product-market fit, customer satisfaction, or value delivery.
