What is Customer Churn? Customer churn means a customer’s ending their relationship with a bank/company for any reason. Although churn is inevitable at a certain level, a high customer churn rate is a reason for failing to reach the business goals. So identifying customers who would churn is very important for business

Context

The Thera bank recently saw a steep decline in the number of users of their credit card, credit cards are a good source of income for banks because of different kinds of fees charged by the banks like annual fees, balance transfer fees, and cash advance fees, late payment fees, foreign transaction fees, and others. Some fees are charged to every user irrespective of usage, while others are charged under specified circumstances.

Customers’ leaving credit cards services would lead bank to loss, so the bank wants to analyze the data of customers and identify the customers who will leave their credit card services and reason for same – so that bank could improve upon those areas
