What Is Net Revenue Retention (NRR)?
Net Revenue Retention (NRR) measures how much revenue is retained from a cohort of existing customers over 12 months, including expansions and contractions. NRR above 100% means the existing base is growing on its own. World-class SaaS businesses often exceed 120% NRR.
Why it matters: this metric helps founders separate random variation from real business movement. Decisions improve when the metric is tracked in trend form, not one-off snapshots.
How to use it in practice: pair this metric with at least one upstream and one downstream signal. That way, you can explain why it changed and what action should come next.
