Customer Churn Rate

Customer Churn Rate refers to the proportion of customers who stop doing business with a company over a certain period. It is a key metric for measuring customer loyalty and business health. In foreign trade, this term is often used to analyze repeat purchases from existing customers. Calculation: Number of churned customers during the period ÷ Total number of customers at the beginning of the period × 100%. Use cases include: evaluating customer relationship management effectiveness, forecasting sales, and developing customer retention strategies. Notes: The statistical period (e.g., quarterly, annual) must be clearly defined; distinguish active churn (customers switching to competitors) from passive churn (customer bankruptcy); in foreign trade, churn caused by cultural differences, payment terms, and logistics issues should be analyzed separately. It is complementary to 'Customer Retention Rate,' but churn rate focuses more on negative changes; compared with 'Customer Acquisition Cost,' it can help determine the cost-effectiveness of retaining existing customers versus acquiring new ones. A high churn rate may indicate problems with product quality, delivery times, or service, requiring timely intervention.
