Churn Rate
Churn rate is the percentage of customers or subscribers who stop using your product or service during a given time period, serving as a key indicator of customer satisfaction and business health.
Churn rate measures customer attrition. If you start a month with 1,000 customers and lose 50, your monthly churn rate is 5%. For subscription businesses, this is one of the most critical metrics because it directly determines whether the business is growing or shrinking.
Gross churn ignores upgrades; net churn factors in expansion revenue from existing customers. Churn has a compounding effect that makes it devastating over time. A 5% monthly churn rate means losing 46% of customers annually.
In practice
- A SaaS company reduced monthly churn from 4% to 2% by implementing an onboarding email sequence that guided new users to their 'aha moment' within the first week
- A subscription box service's churn spiked to 15% after a price increase, they introduced a loyalty tier with grandfathered pricing for long-term subscribers, reducing churn to 6%
- A B2B platform identified through data analysis that customers who used 3+ features in their first month had 80% lower churn, they restructured onboarding to ensure feature adoption
- A streaming service analyzed churn cohorts and found users who joined during a free trial promotion churned at 3x the normal rate, they switched to a paid trial model with better retention
