Frequently Asked Questions
What is customer retention rate?
Customer retention rate is the percentage of existing customers who stay with your business over a specific period. Formula: Retention Rate = (Total Customers at End - New Customers) ÷ Existing Customers at Start.

What is the difference between retention and churn?
Retention and churn are opposites: Retention = % kept, Churn = % lost. They add up to 100%. A 85% retention rate means 15% churn. Retention focuses on keeping customers; churn measures how many leave. Both track the same behavior from different angles.
What is the retention rate formula?
Retention Rate = (Retained Customers ÷ Existing Customers) × 100. Where Retained = Total at End - New Customers. Example: Start 1,000, End 950, New 100 → Retained = 950-100 = 850. Retention = 850÷1,000 = 85%.
How does retention relate to customer lifetime value (CLV)?
