Learn how to calculate and reduce customer churn
Customer churn rate measures the percentage of customers who stop using your service during a given time period. It’s one of the most critical metrics for subscription businesses.
How to Calculate Churn Rate
The basic churn rate formula is:
Churn Rate = (Customers Lost During Period / Customers at Start of Period) × 100
For example, if you started the month with 1,000 customers and lost 50, your monthly churn rate would be 5%.
Why Churn Rate Matters
Understanding churn is essential for sustainable growth because acquiring new customers is typically 5-25 times more expensive than retaining existing ones. A high churn rate can severely impact your growth and profitability.
Types of Churn
Customer Churn: The percentage of customers who cancel
Revenue Churn: The percentage of revenue lost from cancellations
Gross Churn: Total churn without considering expansions
Net Churn: Churn minus expansion revenue from existing customers
