What is Net Revenue Retention?

Net Revenue Retention (NRR) measures how much revenue you retain and grow from existing customers, excluding new customer acquisition. It's the ultimate measure of product value.

Formula:

NRR = (Start MRR + Expansion - Contraction - Churn) / Start MRR × 100

Benchmarks:

  • 130%+: World-class (top SaaS companies)
  • 110-130%: Excellent - strong expansion
  • 100-110%: Good - slight net growth
  • <100%: Warning - losing revenue from existing customers

NRR > 100% means you're growing revenue even without new customers. The best SaaS companies achieve 120-150% NRR.

Frequently Asked Questions

What's the difference between NRR and GRR? ▼
GRR (Gross Revenue Retention) excludes expansion revenue - it only measures how much you retain. GRR maxes out at 100%. NRR includes expansion, so it can exceed 100%. GRR shows retention health; NRR shows overall customer revenue growth.
Why is NRR so important for SaaS? ▼
NRR shows if your product delivers increasing value over time. High NRR means customers use more, upgrade plans, and stick around. It's the best predictor of sustainable growth - companies with >130% NRR can grow even without new sales. Investors love high NRR.
How can I improve NRR? ▼
Three levers: (1) Reduce churn through better onboarding and customer success, (2) Reduce downgrades by ensuring customers use full product value, (3) Increase expansion through upsells, cross-sells, and usage-based pricing that grows with customer success.
Should I measure monthly or annual NRR? ▼
Both! Monthly NRR shows trends and helps you react quickly. Annual NRR is what investors typically ask for and smooths out monthly fluctuations. Be consistent in how you report it - some companies use trailing 12-month NRR.

Did you know 80% of software features are rarely or never used? That's a lot of wasted effort.

SaaS software companies spend billions on unused features. In 2025, it was $29.5 billion.

We saw this problem and decided to do something about it. Product teams needed a better way to decide what to build.

That's why we created ProductLift - to put all feedback in one place, helping teams easily see what features matter most.

In the last five years, we've helped over 3,051 product teams (like yours) double feature adoption and halve the costs. I'd love for you to give it a try.
