Net Revenue Retention (NRR)

NRR captures the full picture of how your existing customer base evolves over time. Unlike simple churn metrics that only measure losses, NRR incorporates expansion revenue, which can offset and even exceed churn. A company with 10% annual gross churn but 20% expansion from upsells achieves an NRR of 110%, meaning the existing cohort grows by 10% year over year without any new customers being added. Public SaaS companies with NRR above 120% consistently command the highest valuation multiples because they demonstrate strong product-market fit, efficient land-and-expand motions, and deep customer stickiness. Achieving high NRR requires a deliberate strategy: build products with natural expansion triggers like seat-based pricing or usage tiers, invest in customer success to drive adoption, and create clear upgrade paths from entry-level plans to enterprise packages. Companies with low NRR should investigate whether the issue is excessive churn, insufficient expansion opportunities, or both.

A collaboration SaaS starts the quarter with $500,000 in MRR from existing customers. During the quarter, those same customers generate $60,000 in expansion revenue through seat additions and plan upgrades, $15,000 in contraction from downgrades, and $25,000 in churn from cancellations. NRR = ($500,000 + $60,000 - $15,000 - $25,000) / $500,000 x 100 = 104%. This means the existing base grew by 4% without any new customer acquisition.
