What is revenue churn?
Revenue churn (or MRR churn) measures the monthly recurring revenue lost due to customer cancellations, downgrades, or non-renewals. It is distinct from customer churn, which counts the number of customers lost.
Formula: Revenue Lost = MRR × (Customer Churn Rate ÷ 100)
For example, if your MRR is $50,000 and your monthly churn rate is 3%, you are losing $1,500 per month — or $18,000 per year — to churn.
Net Revenue Churn can be negative if expansion revenue (upgrades, upsells) from existing customers exceeds churned revenue. Negative net revenue churn is a strong indicator of a healthy SaaS business.
