Churn Rate Calculator
Measure how many customers you lose each month and how long the average customer stays. Lower churn means more stable, predictable revenue.
Calculate your churn rate
Customer lifetime in months equals 1 divided by the churn rate.
How it works
Churn rate shows the share of customers you lose in a month and what that means for retention and lifetime.
