Contraction Rate

Contraction rate is the share of recurring revenue lost when existing customers downgrade or drop part of their subscription without churning entirely.

Contraction is not churn; the customer stays but pays less, and that is what separates it from full churn. Its importance is that it is an early warning: a customer who downgrades often leaves entirely a few months later, so contraction usually moves ahead of churn. Its opposite is expansion, and net revenue retention is the sum of these two forces alongside churn. The analytical trap is that contraction hides in user-count metrics: the number of active customers stays flat and everything seems fine, while revenue quietly bleeds. So contraction is visible only with revenue data, not a user count. And like all subscription revenue metrics, it comes from the billing system, not site behaviour.
