Customer Defection Rate (CDR) %:

Customer Defection Rate (CDR) is a crucial business metric that shows the percentage of customers who stop using a company’s product or service over a certain period. Tracking this rate helps businesses identify retention issues and improve customer loyalty strategies.

Formula
Customer Defection Rate is calculated by dividing the number of customers who defected (CD) by the total number of customers (C), then multiplying by 100 to get a percentage.
So, CDR = (CD ÷ C) × 100
