Churn Cohort
Intermediate PronunciationEN/tʃɜːrn ˈkoʊhɔːrt/
A churn cohort is a group of users who stopped using a product within the same time window and are analysed together to understand why they left.
Membership follows from the churn definition, either an explicit cancellation or crossing an inactivity threshold. The analytical value lies in what happened before the exit: the final sessions, repeated errors, and the features that were never touched. The reading goes wrong when the threshold is forgotten as a choice, because shortening it enlarges the churn cohort without any change in user behaviour.
FAQ
A churned user is one person who met the churn condition. A churn cohort is a set of such people who left in the same window, and that shared timing is what makes it possible to see the effect of a product change or an external event on their exit.
