Net Revenue Retention (NRR)

Net Revenue Retention is the percentage of recurring revenue retained from existing customers over a given period, accounting for expansion, contraction, downgrades, and churn.

The formula is straightforward: (Starting ARR + Expansion - Contraction - Churn) / Starting ARR x 100. An NRR of 106% means your existing customer base grew 6% without a single new logo.

NRR is the single most important metric for SaaS valuation. Public SaaS companies with NRR above 120% trade at median multiples 2-3x higher than those below 100%. For PE-backed companies approaching exit, every point of NRR improvement translates directly to enterprise value.

The challenge is that NRR is a lagging indicator. By the time it drops below 100%, the underlying problems (poor onboarding, weak expansion motion, reactive CS, misaligned selling proposition) have been compounding for 6-12 months. Waiting for NRR to signal trouble means you're already paying the Churn Tax.

A mature post-sale revenue engine targets NRR of 105-115% at scale. Getting there requires three things: reducing gross churn to 6% or below, building a CS-driven expansion motion that contributes 30%+ of growth, and aligning sales, product, and CS on shared retention metrics.
