What is Churn Rate?

Churn rate is the percentage of customers who stop using a company's product or service over a specific period. It is a critical metric for subscription-based businesses, as high churn can severely impact revenue and growth.

For Startups: For startups, a high churn rate can be a sign of poor product-market fit, inadequate customer support, or a flawed pricing model. Reducing churn is often more cost-effective than acquiring new customers and is crucial for long-term survival.

For SaaS: In the SaaS industry, there are two types of churn: customer churn (logo churn) and revenue churn. Revenue churn, which includes downgrades, is often considered more important as it directly reflects the financial impact. A low churn rate, especially negative revenue churn (where expansion revenue from existing customers exceeds lost revenue), is a strong indicator of a healthy SaaS business.

Calculation: Customer Churn Rate = (Number of customers lost in a period / Number of customers at the start of the period) * 100. For instance, if a company loses 10 out of 200 customers in a month, the monthly churn rate is 5%.
