Churn Rate

Churn rate is the silent killer of subscription and recurring-revenue businesses. Even small monthly churn rates compound devastatingly over time. A 5% monthly churn rate means you lose nearly half your customers every year. A 2% monthly churn rate still means losing 22% annually. Every customer lost must be replaced before any net growth can occur.

Understanding why customers churn is as important as measuring the rate. Common causes include poor onboarding (customers never experience the product's value), unresolved support issues, price sensitivity, competitive alternatives, and changing customer needs. Categorizing churn by reason enables targeted interventions. Involuntary churn (expired credit cards) is solved differently from voluntary churn (dissatisfied customers).

Reducing churn has an outsized impact on growth. If a company acquires 100 new customers per month and churns 8%, it needs to acquire 100 customers just to maintain its base before growing. Reducing churn to 4% effectively doubles the impact of acquisition spending. Mathematically, a 1% reduction in churn often creates more value than a 10% increase in new customer acquisition.
