Customer Churn rate (also known as attrition rate), in its simplest terms, is a measure of the number of customers ceasing the relationship with their current service provider on the basis of dissatisfaction. Customer churn is when an existing customer, user, player, subscriber or any kind of return client stops doing business or ends the relationship with a company. This could, for example, mean cancellation of a subscription, non-renewal of a contract or service agreement, ending of a membership or Consumer decision to shop at another store/use another service provider.
