Frequently Asked Questions
What is Revenue Churn?
Revenue churn measures the percentage of recurring subscription dollars lost over a given period due to customer cancellations (churn) and plan downgrades (contraction).
What is the difference between Gross Revenue Churn and Net Revenue Churn?
Gross Revenue Churn looks only at lost dollars (cancellations + downgrades). Net Revenue Churn subtracts expansion MRR gained from existing accounts.
Can Net Revenue Churn be negative?
Yes! Negative net revenue churn occurs when expansion MRR from existing customers exceeds lost revenue from cancellations and downgrades.
What is the formula for Gross Revenue Churn?
Gross Revenue Churn % = [(Churned MRR + Contraction MRR) / Starting MRR] × 100.
What is the formula for Net Revenue Churn?
Net Revenue Churn % = [(Churned MRR + Contraction MRR − Expansion MRR) / Starting MRR] × 100.
Why is Revenue Churn more informative than Customer Logo Churn?
Because losing a $10,000/mo enterprise account has a vastly different financial impact than losing a $20/mo self-serve account.
What is a healthy monthly Gross Revenue Churn rate for B2B SaaS?
For Enterprise SaaS, monthly gross churn should be below 0.5%–1.0%. For Mid-Market, below 1.0%–1.5%. For SMB SaaS, below 2.0%–3.0%.
