The Net Revenue Retention (NRR) Calculator measures the percentage of recurring revenue retained from existing customers over a specific period, factoring in expansion revenue, downgrades, and churn. It is widely considered the single most predictive metric for long-term SaaS enterprise valuation.
Mathematical Formula
NRR (%) = ((Starting MRR + Expansion - Downgrades - Churn) / Starting MRR) * 100
Performance Benchmarks
- 120%+ (Best-in-Class): World-class enterprise software companies (e.g., Snowflake, Twilio). The business compounds organically with zero marketing spend.
- 100% to 120% (Good): Healthy expansion outpacing logo attrition.
- Under 100% (Concerning): Net revenue contraction. Indicates weak product-market fit or leaky retention.
