Net Revenue Retention (NRR) Calculator
Compute Net Revenue Retention (NRR / NDR) — the single best leading indicator of a SaaS company's expansion engine.
What NRR Tells You
Net Revenue Retention (NRR), sometimes called Net Dollar Retention (NDR), measures what happened to a cohort of customers from one period to the next. Starting with $5M ARR, if at year-end the SAME cohort produces $5.75M, your NRR is 115% — even if you brought in zero new customers. This makes NRR the single most powerful predictor of SaaS growth: a company with 130%+ NRR can grow 30% per year without acquiring a single new logo.
The formula: NRR = (Starting ARR + Expansion − Contraction − Churn) / Starting ARR. Critical: only count expansion/contraction/churn from the SAME cohort — new logo revenue is excluded. Source: Bessemer Cloud Index 2026, OpenView Benchmarks. Last updated: May 2026.
NRR Benchmarks for 2026
| NRR | Tier | Examples |
|---|---|---|
| 140%+ | Best-in-class | Snowflake, MongoDB, Datadog (pre-2024) |
| 120-140% | Top quartile | HubSpot, Atlassian, ServiceNow |
| 110-120% | Healthy median | Most public SaaS |
| 100-110% | Below median | Mature or commoditizing SaaS |
| <100% | Concerning | Often signals product-market fit issues |
How to Improve NRR
Three levers, in order of typical impact: (1) Reduce churn — fix activation, onboarding, and identify churn-risk indicators 60-90 days before cancellation. Each 1% churn reduction adds 12 percentage points to annual NRR. (2) Drive expansion — usage-based pricing, seat expansion, feature upsells, multi-product cross-sell. (3) Reduce contraction — make downgrades a manual process (not a self-service path), offer pause options, address the underlying utilization issue.
GRR vs NRR: The Other Half of the Story
Gross Revenue Retention (GRR) = (Starting ARR − Contraction − Churn) / Starting ARR. GRR is bounded by 100% (you can't have more than starting ARR if you exclude expansion). NRR can exceed 100% via expansion. Healthy GRR: 90%+ enterprise SaaS, 80%+ mid-market, 70%+ SMB. Low GRR with high NRR signals expansion is masking high churn — fragile growth.
