SaaS Metrics
Net Revenue Retention (NRR)
Net Revenue Retention (NRR), also called Net Dollar Retention (NDR), measures how much revenue you keep and grow from your existing customer base — excluding new customers entirely. It's the purest measure of product value.
Formula
NRR = (Starting MRR + Expansion - Contraction - Churn) / Starting MRR × 100Example
- Starting MRR: $100,000
- Expansion MRR: $15,000 (upgrades, upsells)
- Contraction MRR: $3,000 (downgrades)
- Churned MRR: $5,000 (cancellations)
NRR = ($100,000 + $15,000 - $3,000 - $5,000) / $100,000 = 107%Benchmarks
| NRR | Assessment |
|---|---|
| < 80% | Leaking revenue — serious problem |
| 80–100% | Average — surviving but not thriving |
| 100–110% | Good — slight organic growth |
| 110–130% | Excellent — strong expansion |
| 130%+ | Elite — Snowflake, Datadog territory |
NRR > 100% means you grow even without acquiring new customers. This is the holy grail of SaaS.
Why Investors Love NRR
NRR above 100% creates a compounding effect: each cohort of customers becomes more valuable over time. This means:
- Revenue is more predictable and durable
- Less dependency on new customer acquisition
- Higher company valuation (high-NRR companies trade at 2–3x higher multiples)
NRR in AI-Run Companies
AI-run companies can drive exceptional NRR through:
- Automated upselling — AI identifies when customers need more and presents the right upgrade at the right time
- Continuous product improvement — AI ships features faster, increasing value and reducing churn
- Proactive support — AI detects issues before customers notice them
- Usage-based pricing — As customers use more, revenue grows naturally
The best AI-run companies on EvolC target NRR above 110% — revenue that grows itself, operated by AI that improves itself.
