📊 Understanding Churn Rate

Churn rate measures the percentage of customers who stopped using your product or service during a given time period.

Churn Rate = (Customers Lost / Starting Customers) × 100

Customers Lost = Starting Customers - Ending Customers + New Customers

Why it matters: A lower churn rate indicates better customer retention. Industry benchmarks vary, but generally, a monthly churn rate below 5% is considered good for most SaaS businesses.
