About the Churn Rate Calculator

Churn rate is the percentage of customers who stop doing business with a company over a given period, a key health metric for subscription and recurring-revenue businesses.

Formula: Churn Rate = (Customers Lost ÷ Customers at Start) × 100 · Retention Rate = 100 − Churn Rate

Lower churn means customers stay longer, which directly increases customer lifetime value and reduces the pressure to constantly acquire new customers.
