Logo churn = customers lost ÷ starting customers (1,000 → 950 = 5%). Revenue churn weights by MRR — losing ten $10 plans hurts less than one $1,000 plan. Track both; revenue churn decides survival.
NRR = (start MRR + expansion − churn − contraction) ÷ start MRR. Example: ($100k + $15k − $8k − $2k) ÷ $100k = 105% — growing without adding a single customer. Best-in-class SaaS runs 110–130%.
SMB SaaS: 3–7% monthly logo churn is typical; enterprise: under 1–2%. Anything above 10% monthly means the bucket leaks faster than sales can fill it — fix onboarding before spending on acquisition.
Average churn blends January signups (settled) with March signups (still onboarding). Cohort curves show whether each signup month retains better than the last — the only view that proves product improvements work.
