What is Net Revenue Retention?
Net Revenue Retention (NRR) measures the percentage of recurring revenue retained from your existing customer base over a given period, including expansion, downgrades, and churn, but excluding revenue from new customers. An NRR above 100% means expansion and upsells inside your existing base are outpacing churn and contraction. Below 100%, your existing customers are collectively worth less than they were a period ago, regardless of how many new logos you signed.
Why NRR catches what MRR misses
Monthly Recurring Revenue (MRR) tells you what is coming in this month. It doesn't tell you whether that revenue is healthy. A company can hit its MRR targets quarter after quarter through new sales while its existing base quietly contracts underneath, a pattern that eventually catches up once new customer acquisition slows or gets more expensive. NRR isolates whether the product itself delivers enough ongoing value to grow revenue from customers already using it.
The NRR formula
NRR = (Starting MRR + Expansion MRR − Downgrade MRR − Churned MRR) ÷ Starting MRR × 100
Each component maps to a different part of the customer relationship:
Expansion MRR: revenue gained from upsells, seat growth, or upgrades within existing accounts.
Downgrade MRR: revenue lost from customers moving to a lower plan or reducing usage.
Churned MRR: revenue lost from customers who cancel entirely.
What drives NRR
NRR is a lagging indicator of a leading cause: whether customers are getting enough value from the product to want more of it. Teams typically influence it through:
Feature adoption: customers who use more of the product are more likely to expand than customers using a narrow slice of it.
Account health monitoring: using a customer health score to catch contraction risk before it becomes churn.
Expansion triggers: surfacing upgrade paths inside the product at the moment a customer hits a usage limit, rather than waiting for a renewal conversation.
Why NRR matters for PLG and hybrid GTM motions
In product-led and hybrid go-to-market models, expansion often happens inside the product itself rather than through a sales-led renewal call. That makes NRR more directly tied to onboarding and adoption quality than in traditional sales-led models: a customer who never fully adopted the product has little basis to expand from. Teams tracking retention and churn alongside NRR get the fullest view of account health.
