Net Revenue Retention (NRR)
A SaaS metric measuring the percentage of recurring revenue retained from existing customers over a period, including expansions, contractions, and churn. An NRR above 100% means expansion revenue from upsells and cross-sells exceeds lost revenue from downgrades and cancellations. AI agents improve NRR by identifying expansion opportunities from product usage signals and automating personalized upsell outreach at scale.

Example
A B2B SaaS company with $10M ARR at the start of the year retains $9.2M of that base but adds $1.5M in expansion revenue from AI-identified upsell opportunities, ending at 107% NRR—meaning the existing customer base alone grew revenue by 7%.
Frequently asked questions
- What is a good NRR benchmark?
- Above 100% is the threshold for growth from existing customers. Top-tier SaaS companies achieve 120-140%. Below 90% signals a retention and expansion problem that needs immediate attention. AI agents typically improve NRR by 10-20 percentage points by systematically identifying expansion opportunities.
