About the Churn Rate Calculator
Calculate churn rate free: customers lost ÷ customers at the start of the period × 100 (retention is simply 100% minus churn). For subscription businesses, churn is the silent killer — 5% monthly churn means losing nearly half your customers within a year, no matter how good acquisition looks. Healthy SaaS aims for 1–2% monthly. Track it monthly, segment it by plan, and treat every improvement as compounding revenue.
