Net Revenue Retention (NRR) measures how much recurring revenue you keep from existing customers over time — including expansions, upgrades, downgrades, and cancellations. The formula is (Starting MRR + Expansion − Contraction − Churn) ÷ Starting MRR × 100. Above 100% means revenue grows from your base alone; best-in-class SaaS exceeds 120%.
What is Net Revenue Retention (NRR) in SaaS?
Net Revenue Retention measures how much recurring revenue you keep from existing customers over time, including expansions, upgrades, downgrades, and cancellations.
👆 By the way, an interesting fact: high-NRR companies (120%+) that are also growing fast (80%+ YoY) have commanded premium revenue multiples of 18-22x; more typical 120%+ NRR companies trade around 7-9x, while those below 100% NRR sit closer to 4-6x.

How to calculate the Net Revenue Retention rate
Net Revenue Retention Formula
NRR = (Starting MRR + Expansion − Contraction − Churn) ÷ Starting MRR × 100Includes expansion — can exceed 100%
Where:
Starting MRR = Monthly Recurring Revenue at period start
Expansion = Additional revenue from existing customers
Contraction = Revenue lost from downgrades
Churn = Revenue lost from cancellations
Example Time
Let’s say:
- Starting MRR: $100,000
- Expansion: $30,000
- Contraction: $5,000
- Churn: $10,000
($100,000 + $30,000 − $5,000 − $10,000) ÷ $100,000 × 100 = 115%Worked example — healthy growth

Net Revenue Retention FAQ
How do you calculate NRR?
(Starting MRR + Expansion − Contraction − Churn) ÷ Starting MRR × 100. $100K start + $30K expansion − $5K contraction − $10K churn = 115% NRR.
What is a good NRR?
Under 100% means net revenue loss; 100–105% is stable; 105–120% is healthy; above 120% is outstanding. High-NRR companies command far higher valuation multiples.
What's the difference between NRR and GRR?
NRR includes expansion revenue and can exceed 100%; GRR excludes expansion and caps at 100%. NRR shows growth; GRR shows pure retention strength.
Why do investors care about NRR?
NRR above 100% means the business grows even without new customers — a strong signal of product-market fit and efficient, compounding growth, which drives premium valuations.
