Customer churn in banking is when a customer closes their account and switches to another bank. Over their customer lifetime, customers generate fees on transactions, banking fees, credit cards, home loans, and personal loans. Churn is a problem, because the bank loses revenue, and it costs more to acquire a new customer than retaining an existing one.
