The formula: NRR = (Starting ARR + Expansion − Contraction − Churn) \u002F Starting ARR × 100. Because it strips out new-customer growth entirely, NRR answers a purer question than overall revenue growth: are the customers we already have becoming more or less valuable over time? A business can have flat or even shrinking new-customer acquisition and still grow overall revenue if NRR is comfortably above 100% — expansion from existing accounts alone drives growth, a dynamic public SaaS companies prize because it means the business compounds even if sales\u002Fmarketing spend is cut. NRR above 100% is considered healthy, 110–120%+ is considered excellent and is common among best-in-class usage-based and seat-expanding B2B SaaS companies (Snowflake, Datadog have historically posted NRR well above 120%), while NRR below 100% signals that expansion and retention aren't offsetting churn and contraction, a structural problem no amount of new-customer acquisition can fix long-term since it means the \"bucket\" is leaking faster than it's being topped up from within. NRR is one of the first metrics public-market and late-stage investors interrogate in SaaS diligence precisely because it isolates product-market fit and expansion motion from the noise (and cost) of new logo acquisition. Concrete worked example: a SaaS company starts the year with $10M ARR from its existing customer base. Over the year, that same cohort adds $2.5M in expansion ARR (upgrades and added seats), loses $0.5M to contraction (downgrades), and loses $1M to churn (cancellations) — entirely excluding any of the $4M in ARR added from brand-new customers signed during the year. NRR = ($10M + $2.5M − $0.5M − $1M) \u002F $10M = 110%. Reported alongside 40% overall ARR growth ($14M ending ARR), this tells investors the growth is durable — not just a function of an aggressive new-sales push papering over a leaky existing base. NRR above 100% is only achievable when expansion revenue outpaces both contraction and churn combined, which is precisely why usage-based and seat-expanding pricing models tend to post structurally higher NRR than flat-fee products — a usage-based customer who simply grows their own business automatically expands their bill without any renegotiation, while a flat-fee customer's spend never grows unless a salesperson actively upsells them to a higher tier.","NRR measures the revenue change from an existing customer cohort over a period, including expansion and contraction but excluding new customers.",null,[11,14,17],{"slug":12,"name":13},"arr","Annual Recurring Revenue (ARR)",{"slug":15,"name":16},"churn","Churn",{"slug":18,"name":19},"mrr","Monthly Recurring Revenue (MRR)",[21,25,29,32,35,38,39,43,46,49,52,55],{"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":12,"category":5,"name":13,"updated_at":24},{"slug":40,"category":5,"name":41,"updated_at":42},"auto-renewal-clause","Auto-Renewal Clause","2026-08-24T02:46:38+00:00",{"slug":44,"category":5,"name":45,"updated_at":42},"build-vs-buy","Build vs. Buy",{"slug":47,"category":5,"name":48,"updated_at":28},"burn-multiple","Burn Multiple",{"slug":50,"category":5,"name":51,"updated_at":42},"burn-rate","Burn Rate",{"slug":53,"category":5,"name":54,"updated_at":24},"cac","Customer Acquisition Cost (CAC)",{"slug":56,"category":5,"name":57,"updated_at":24},"cdn","Content Delivery Network (CDN)"]
