Churn is the inverse of retention and the single most leveraged number in subscription businesses. Logo churn counts customers; revenue churn counts dollars (and is usually lower because larger accounts retain better). Gross churn measures lost revenue; net churn includes expansion and goes negative for best-in-class B2B SaaS. Benchmarks vary widely: consumer SaaS often runs 3-7% monthly logo churn; mid-market B2B 1-2% monthly; enterprise <1%. Churn surveys (exit interviews + churn-reason classification) are the highest-ROI survey program most teams under-invest in. ## Formula `Monthly Churn Rate = (Customers lost in month / Customers at start of month) × 100` ## Example Start of March: 2,000 customers. Lost 50 by month end. Churn = 50/2000 = 2.5%. Annualized: roughly 26% (compound). ### Run a Churn Rate survey free SpaceForms includes pre-built templates with validated wording.
