{"schema":"askedwell-answer-v1","url":"https://askedwell.com/pages/what-is-the-difference-between/churn-rate-vs-retention-rate","question":"What is the difference between churn rate and retention rate?","short_answer":"Churn rate is the percentage of customers or revenue LOST in a period; retention rate is the percentage KEPT. For simple logo counts they are exact complements (retention = 100% − churn). For revenue they are NOT: expansion from existing customers can push net revenue retention above 100% while gross logo churn stays positive.","long_answer":"**The complement that is not always a complement**\n\nFor a simple customer (logo) count, churn and retention are two sides of one coin. Start a month with 100 customers, lose 5, and your customer churn is 5% while your customer retention is 95% — they sum to 100%. The moment you measure REVENUE instead of logos, that clean complement breaks, because existing customers can spend more (expansion) or less (contraction), not just stay or leave.\n\n**Side-by-side comparison**\n\n| Property | Churn rate | Retention rate |\n|---|---|---|\n| Measures | Customers/revenue lost | Customers/revenue kept |\n| Direction | Lower is better | Higher is better |\n| Logo-level relationship | Retention = 100% − churn | Churn = 100% − retention |\n| Revenue-level relationship | NOT a simple complement (expansion breaks it) | Net retention can exceed 100% |\n| Common ceiling | 0% (perfect) | 100% logo / >100% net revenue |\n| Best for | Spotting leakage, cohort decay | Spotting durability, expansion engine |\n| Investor headline | Gross churn (risk) | Net Revenue Retention (growth quality) |\n\n**Customer churn vs revenue churn**\n\n- Customer (logo) churn: customers_lost ÷ customers_at_start. Counts heads.\n- Revenue churn: MRR_lost ÷ MRR_at_start. Counts dollars. A single enterprise account leaving can be 0.5% logo churn but 15% revenue churn — same event, wildly different magnitude depending on which lens you use.\n\n**Gross vs net (the distinction that matters most)**\n\n- Gross Revenue Retention (GRR): (starting MRR − churn − contraction) ÷ starting MRR. It CAPS at 100% because it ignores expansion. A pure measure of how much of the existing base you keep.\n- Net Revenue Retention (NRR): (starting MRR − churn − contraction + expansion) ÷ starting MRR. It can EXCEED 100%. A best-in-class SaaS company can post 120% NRR (the existing base grows 20%) while still losing 8% of its logos to churn. Both numbers are true at the same time.\n\n**Why NRR above 100% is the holy grail**\n\nIf NRR exceeds 100%, the company grows revenue even if it acquires zero new customers — the existing book expands faster than it leaks. Top public SaaS companies have reported NRR of 130%+. This is why investors quote NRR, not churn alone: churn tells you the size of the leak; NRR tells you whether the bucket fills faster than it drains.\n\n**Benchmarks (directional, not advice)**\n\n- SMB SaaS: 3-5% monthly logo churn is common; NRR 90-100%\n- Mid-market: 1-2% monthly churn; NRR 100-110%\n- Enterprise: under 1% monthly churn; NRR 110-130%+\n\n**The annualization trap**\n\n5% monthly churn does NOT equal 60% annual churn. Churn compounds on a SHRINKING base: (1 − 0.05)^12 ≈ 0.54, so annual retention is ~54% and annual churn ~46% — not 60%. Multiplying monthly churn by 12 always overstates the loss.\n\n**Cross-reference:** see /pages/what-is/churn-rate + /pages/what-is/lifetime-value + /pages/what-is-the-difference-between/mrr-and-arr.","duration_iso":"PT0M","ranges":[{"condition":"Logo-level complement","duration":"retention = 100% − churn (always)"},{"condition":"GRR ceiling","duration":"100% (cannot exceed — ignores expansion)"},{"condition":"NRR ceiling","duration":"unbounded (best-in-class 120-130%+)"},{"condition":"5% monthly churn annualized","duration":"~46% (compounded, NOT 60%)"},{"condition":"Enterprise best-practice monthly churn","duration":"under 1%"}],"variables":[{"name":"Measurement unit","effect":"Logos make churn and retention exact complements; revenue does not (expansion + contraction)"},{"name":"Expansion revenue","effect":"When present, NRR can exceed 100% even while gross logo churn stays positive"},{"name":"Customer segment","effect":"SMB churns faster (3-5%/mo) than enterprise (under 1%/mo)"},{"name":"Time window + compounding","effect":"Monthly churn compounds on a shrinking base — never multiply by 12"}],"sources":[{"label":"David Skok, \"SaaS Metrics 2.0\"","tier":2,"url":"https://www.forentrepreneurs.com/saas-metrics-2/","note":"Canonical churn/retention definitions + the \"negative churn\" concept"},{"label":"Bessemer Venture Partners \"State of the Cloud\"","tier":1,"url":"https://www.bvp.com/atlas","note":"Net Revenue Retention benchmarks for public SaaS companies"},{"label":"ChartMogul SaaS Metrics Guide","tier":2,"url":"https://chartmogul.com/saas-metrics/","note":"GRR vs NRR calculation + edge cases (contraction, mid-period upgrades)"},{"label":"Lincoln Murphy, Customer Success (Sixteen Ventures)","tier":3,"note":"Logo vs revenue retention; net negative churn for customer-success teams"},{"label":"Paddle / ProfitWell retention research","tier":2,"note":"Monthly + annual churn benchmarks segmented by SMB / mid-market / enterprise"}],"faq":[{"question":"Is churn rate just 100% minus retention rate?","answer":"Only for simple LOGO counts. For revenue, no: expansion from existing customers means Net Revenue Retention can exceed 100% while gross logo churn is still positive. A company can lose 8% of logos (8% churn) yet post 120% NRR because the remaining customers expanded. Always specify whether you mean logo or revenue, gross or net."},{"question":"What is the difference between gross and net retention?","answer":"Gross Revenue Retention (GRR) counts only what you KEEP from the starting base — it caps at 100% and ignores expansion. Net Revenue Retention (NRR) adds expansion revenue, so it can exceed 100%. GRR shows how leaky the bucket is; NRR shows whether expansion outpaces the leak. Investors quote both: GRR for risk, NRR for growth quality."},{"question":"Why does 5% monthly churn not equal 60% annual churn?","answer":"Because churn compounds on a SHRINKING base, not a fixed one. Each month you lose 5% of whoever is left, not 5% of the original cohort. (1 − 0.05)^12 ≈ 0.54, so about 54% are retained and 46% churned annually — not 60%. Multiplying monthly churn by 12 always overstates the annual loss."},{"question":"Should I track customer churn or revenue churn?","answer":"Track both. Customer (logo) churn shows how many relationships you are losing; revenue churn shows the financial impact, which can differ wildly when customers vary in size. A SaaS with a few large enterprise accounts cares most about revenue churn (one logo = big dollars); a high-volume consumer app watches logo churn (each customer ≈ same value)."}],"keywords":["churn rate vs retention rate","difference between churn and retention","gross vs net revenue retention","NRR vs GRR","customer churn vs revenue churn","SaaS retention metrics"],"category":"business","date_published":"2026-05-29","date_modified":"2026-05-29","license":"CC-BY-4.0","attribution":"https://askedwell.com"}
