Frequently Asked Questions (FAQ)

What is customer retention rate?
Customer retention rate measures the percentage of customers a company retains over a specific period. It indicates how well a business keeps its existing customers and is calculated as: (Total Customers - New Customers) / Existing Customers × 100.
What is attrition rate?
Attrition rate (also called churn rate) is the percentage of customers who stop doing business with a company during a specific period. It is calculated as: 100% - Customer Retention Rate.
How do I interpret the results?
A higher retention rate (closer to 100%) indicates better customer loyalty and satisfaction. Industry benchmarks vary, but generally: 90%+ is excellent, 80-90% is good, 70-80% is average, and below 70% may indicate issues that need addressing.
