Understanding Net Revenue Retention

What is Net Revenue Retention (NRR)?

Net Revenue Retention (NRR), also known as Net Dollar Retention, is a metric that measures the percentage of recurring revenue retained from existing customers over a given period. It includes all revenue changes, such as upgrades (expansion), downgrades (contraction), and cancellations (churn). NRR tells you how much your revenue would grow or shrink if you didn’t acquire any new customers.

What’s a Good NRR?

Less than 100%: This means that for every dollar you started with, you have less than a dollar a year later. Your business is losing revenue from its existing customer base faster than it can grow it.
Exactly 100%: You are breaking even. Your expansion revenue perfectly offsets the revenue you lose to churn and contraction.
Over 100%: This is the goal for a healthy SaaS business. It means your existing customers are spending more over time, creating “negative churn” and a powerful engine for growth. Top-tier public SaaS companies often have an NRR of 120% or more.
