Key indicator that measures the loss of customers. Also called attrition rate.
It can concern customers that did not buy a product again or that have left the company in a specific period of time.
The churn is calculated as follows :
Number of customers lost / Total number of customers.
A low rate means that customers are loyal and thus, satisfied by the brand. This has consequences on the company’s profitability in the short, middle and long term.
