Net Revenue Retention (NRR): The percentage of recurring revenue retained from existing customers including expansion and churn. Above 100% means you grow even without new customers. Best SaaS companies have 120%+ NRR.
The power of low churn: At 2% monthly churn, you lose ~22% of revenue annually. At 5% monthly churn, you lose ~46%. Small churn improvements compound massively.
Expansion revenue: Upsells and upgrades from existing customers. The best SaaS businesses generate more expansion than they lose to churn, achieving "negative churn."
