Churn Rate Calculator
Find your customer churn and retention rate.
Measure who is leaving
Churn rate is the heartbeat metric of any subscription business: the share of customers who cancel over a period. Small differences compound hugely over time, so tracking it closely matters.
Losing 25 of 500 customers in a month is a 5% churn rate and 95% retention. Because retained customers keep paying, cutting churn is often more valuable than winning new sign-ups.
