Retention Curve
A tool that tracks the proportion of a cohort of users still active at various points in time after registration. It is used to assess product-market fit and whether long-term growth exhibits compounding effects.
Timeline (last 90 days)
Retention curves are a core tool for judging product-market fit, and a typical approach is to track the active proportion of the same cohort of users on days 1, 7, 30 and 90 after registration.
If a retention curve flattens at a certain level (i.e., "flattening"), it indicates the existence of a stable core user base.
For a product with true PMF, its user retention curve flattens out after a certain point rather than continuing to decline to zero.
In SaaS and subscription products, retention curves are usually presented through cohort analysis, and the key criterion is whether a non-zero stable retention baseline exists.
Involuntary churn refers to users losing service passively due to payment failures, expired cards, or platform outages rather than actively canceling their subscriptions, and this type of churn tends to lower renewal rates and retention curves.
