It comes in two primary flavors: customer churn (the percentage of customers who cancel, regardless of their plan size) and revenue churn \u002F MRR churn (the percentage of recurring revenue lost, which weights by dollar value and better reflects business impact when plan sizes vary widely). The standard formula for monthly customer churn is: (customers lost during the month) \u002F (customers at the start of the month) × 100. A SaaS business starting the month with 1,000 customers and losing 30 has a 3% monthly churn rate — which compounds brutally over a year: at a flat 3%\u002Fmonth, roughly 30% of the starting cohort is gone within 12 months even before accounting for any growth. Churn is the metric that makes or breaks SaaS unit economics, because it directly determines customer lifetime (Lifetime ≈ 1 \u002F churn rate) and therefore LTV — a business with 5% monthly churn has an average customer lifetime of just 20 months, while 1% monthly churn implies 100 months (over 8 years), radically changing how much can profitably be spent on CAC. Benchmark expectations vary sharply by segment: consumer\u002FSMB SaaS often runs 3–7% monthly churn (considered acceptable given lower ACV), while enterprise SaaS with annual contracts and dedicated CSMs typically targets under 1% monthly (under ~10-12% annual) churn. Builders reduce churn through better onboarding\u002Factivation, proactive customer success outreach triggered by usage-drop signals (a \"health score\" dropping below a threshold), win-back campaigns for canceled accounts, and — increasingly — in-product cancellation flows that offer a discount or pause option before letting a user leave, capturing save data on cancellation reasons. Concrete worked example: a project management SaaS notices via product analytics that accounts which don't create a second project within 14 days of signup churn at 3x the rate of those that do. The team builds an automated email + in-app nudge triggered exactly at day 10 for accounts with only one project, cutting that cohort's 60-day churn from 24% to 15% — a direct, measurable churn intervention driven by usage data rather than guesswork. Churn is also worth splitting into voluntary churn (a customer actively decides to cancel) and involuntary churn (a payment simply fails and the account lapses, see dunning) — the two require completely different fixes, since voluntary churn is a product\u002Fvalue problem solved by improving retention and engagement, while involuntary churn is a billing-infrastructure problem often solved with better payment retry logic alone, with no product change required at all.","Churn is the rate at which customers cancel or stop paying for a subscription over a given period — the single biggest threat to SaaS growth.",null,[11,14,17],{"slug":12,"name":13},"cohort","Cohort",{"slug":15,"name":16},"ltv","Customer Lifetime Value (LTV)",{"slug":18,"name":19},"mrr","Monthly Recurring Revenue (MRR)",[21,25,29,32,35,38,41,45,48,51,54,57],{"slug":22,"category":5,"name":23,"updated_at":24},"activation","Activation","2026-08-24T02:46:36+00:00",{"slug":26,"category":5,"name":27,"updated_at":28},"aha-moment","Aha Moment","2026-08-24T02:46:37+00:00",{"slug":30,"category":5,"name":31,"updated_at":28},"annual-contract-value","Annual Contract Value (ACV)",{"slug":33,"category":5,"name":34,"updated_at":24},"api-first","API-First",{"slug":36,"category":5,"name":37,"updated_at":24},"arpa","Average Revenue Per Account (ARPA)",{"slug":39,"category":5,"name":40,"updated_at":24},"arr","Annual Recurring Revenue (ARR)",{"slug":42,"category":5,"name":43,"updated_at":44},"auto-renewal-clause","Auto-Renewal Clause","2026-08-24T02:46:38+00:00",{"slug":46,"category":5,"name":47,"updated_at":44},"build-vs-buy","Build vs. Buy",{"slug":49,"category":5,"name":50,"updated_at":28},"burn-multiple","Burn Multiple",{"slug":52,"category":5,"name":53,"updated_at":44},"burn-rate","Burn Rate",{"slug":55,"category":5,"name":56,"updated_at":24},"cac","Customer Acquisition Cost (CAC)",{"slug":58,"category":5,"name":59,"updated_at":24},"cdn","Content Delivery Network (CDN)"]
