Churn Rate
The percentage of customers who stop using a product or service during a given time period. Reducing churn is often more cost-effective than acquiring new customers.
What does Churn Rate mean?
Churn rate is the percentage of customers who cancel or stop using a product within a given period, usually calculated monthly or annually against the starting customer base. It is a central health metric for subscription and SaaS businesses because it directly caps how fast recurring revenue can grow.
Why does Churn Rate matter?
Reducing churn is generally cheaper than acquiring new customers to replace lost ones, and trust plays a role here too: customers who feel confident in ongoing value, supported by visible product updates, testimonials from similar users, or transparent communication, are less likely to question whether to renew.
How is Churn Rate applied in practice?
Churn is measured by comparing customer counts or revenue at the start and end of a period, often segmented by cohort or plan tier, and retention initiatives such as onboarding improvements or proactive support are tested against a control group to confirm they actually reduce churn rather than just shift its timing.
