Frequently Asked Questions

Customer churn rate is calculated as customers lost during the period divided by customers at the start of the period, multiplied by 100. New customers are shown in the flow breakdown but are not included in the churn denominator.

Benchmarks vary by industry and customer segment. This calculator treats roughly 2–5% monthly churn as a healthy operating range, with lower churn marked as safest and higher churn flagged for retention action.

Churn measures the share of existing customers who left. Including new customers in the denominator can hide retention problems because growth inflates the base while customer losses remain unchanged.
