📖 What is Revenue Churn?

Revenue churn rate is a critical metric for measuring SaaS business health, reflecting the percentage of revenue lost due to customer downgrades, cancellations, or churn. Healthy SaaS companies typically keep monthly revenue churn below 3%. Net Revenue Retention (NRR) above 100% means expansion revenue from existing customers fully offsets churned revenue — one of the most important metrics investors track. Regular churn monitoring helps customer success teams identify at-risk accounts before they cancel.
