Logo churn vs revenue churn: what's the difference?
Logo churn is the percentage of customers who leave; revenue churn is the percentage of recurring revenue you lose. They differ because customers pay different amounts and existing ones can expand. Net revenue retention folds expansion in, so it can exceed 100% even while you lose logos. Track both.
Logo churn: counting customers
Logo churn is the share of customers who cancel in a period — a simple headcount. If 100 customers start the month and 4 leave, monthly logo churn is 4%. As a rough healthy range, monthly logo churn tends to run 3-5% for SMB, 1-2% for mid-market and under 1% for enterprise (ranges distilled from SaaS metrics literature, read by segment).
Revenue churn: counting dollars
Revenue churn is the share of recurring revenue lost. It can differ sharply from logo churn: lose one big account and revenue churn spikes while logo churn barely moves. Gross revenue churn counts only what you lost; it ignores the extra money existing customers may have started paying.
Net revenue retention (NRR)
NRR starts from a cohort's revenue, subtracts churn and downgrades, and adds expansion. Above 100% means expansion outweighs losses — the sign of a compounding retention engine. The classic benchmark is NRR at or above 100% (annual), but that is really an enterprise and mid-market bar: most low-ARPA SMB SaaS sit well below it, and that is normal, not failure.
Monthly vs annual: the mistake that flatters you
Churn compounds. A 4% monthly logo churn is not 4% a year — it is roughly 39% a year once it compounds. Founders who quote a monthly churn figure against an annual benchmark make a business that is quietly bleeding look healthy. Startkeel benchmarks retention on an annual basis and states which basis a number is on, so the comparison is honest.
FAQ
Can revenue churn be negative?
Effectively yes — when expansion from existing customers exceeds what you lose, net revenue churn is negative, which is the same as net revenue retention above 100%.
Which should a bootstrapped SaaS watch?
Both. Logo churn tells you whether the product retains people; revenue churn and NRR tell you whether the economics compound. A low-ARPA SMB SaaS rarely reaches 100% NRR, and that is normal rather than a red flag.
