What is Net Revenue Retention (NRR) and Why it Matters

Bysoftwareexplain Joseph

When SaaS companies measure growth, they often focus on new customer acquisition. But the real signal of long-term health is whether existing customers are worth more over time. That’s what Net Revenue Retention (NRR) tells you.

NRR shows how much recurring revenue you keep—and expand—from your current customer base. It’s one of the most important SaaS metrics for investors, operators, and customer success teams.

What Is Net Revenue Retention (NRR)?

Definition:
Net Revenue Retention (NRR) is the percentage of recurring revenue retained from existing customers after including expansions, downgrades, and churn.

Formula:

NRR = (Starting MRR + Expansion – Contraction – Churn) ÷ Starting MRR × 100
  • Starting MRR/ARR = recurring revenue at the start of the period
  • Expansion = upsells, cross-sells, usage increases
  • Contraction = downgrades or discounts
  • Churn = lost customers or revenue

Example: NRR in Action

Imagine your SaaS company starts January with $100,000 MRR from existing customers.

  • $20,000 expansion (upsells and add-ons)
  • $5,000 contraction (downgrades)
  • $10,000 churn (lost customers)
NRR = (100,000 + 20,000 – 5,000 – 10,000) ÷ 100,000 × 100
NRR = 105%

That means your existing customers grew your revenue by 5%—without any new sales.

Why NRR Matters for SaaS

1. Predictable Growth Engine

When NRR is above 100%, your customer base is expanding revenue on its own. This creates a compounding growth effect without needing constant new leads.

2. Investor Valuation Signal

VCs and public markets look closely at NRR. SaaS companies with 120%+ NRR often command higher revenue multiples because it shows durable, organic growth.

3. Customer Success Scorecard

NRR reflects whether your product is truly sticky. If customers expand over time, it’s proof they’re finding ongoing value.

4. Budget and Strategy Alignment

Tracking NRR helps you balance where to invest: retention, upselling, or acquisition. It’s a direct measure of ROI from customer success programs.

What Is a Good NRR Benchmark?

  • <100% = shrinking customer base; red flag.
  • 100% = flat; customers cover their spend but no expansion.
  • 110%–120% = strong; signals product-market fit and upsell success.
  • 130%+ = world-class; typical of top enterprise SaaS companies.

FAQs on NRR

1. What’s the difference between NRR and GRR?
Gross Revenue Retention (GRR) only measures retention and churn. NRR adds expansions, giving a fuller growth picture.

2. Can NRR be more than 100%?
Yes. Anything above 100% means your customer base is expanding revenue even without new sales.

3. How often should NRR be tracked?
Monthly and quarterly are common. Quarterly gives stability, monthly catches trends earlier.

4. Does NRR include new customers?
No. NRR only measures existing customers. New logos are excluded.

5. Why do investors prioritize NRR?
It’s one of the clearest predictors of sustainable SaaS growth and valuation multiples.
