What is NRR (Net Revenue Retention)?

Net Revenue Retention (NRR) — also called Net Dollar Retention (NDR) — measures how much revenue a company retains from its existing customer base over a period, accounting for expansion revenue (upsells, cross-sells) as well as churn and contraction. NRR = (Starting MRR + Expansion MRR - Churn MRR - Contraction MRR) ÷ Starting MRR × 100. NRR above 100% means the existing customer base grows revenue without new customers — considered the hallmark of a great B2B SaaS business. Best-in-class SaaS companies achieve NRR of 120-140%+.

NRR (Net Revenue Retention) is a critical concept for any B2B revenue team because it directly impacts pipeline predictability and revenue growth. Without a clear understanding of NRR (Net Revenue Retention), teams often make decisions based on incomplete information or misaligned frameworks — leading to poor forecasting, wasted outreach effort, and missed quota. DevCommX incorporates NRR (Net Revenue Retention) thinking into every Revenue Operations engagement we run.

NRR (Net Revenue Retention) is closely connected to ARR (Annual Recurring Revenue) and Churn Rate, and several other core GTM concepts. In the context of GTM Engineering, NRR (Net Revenue Retention) typically informs how revenue systems are designed, what data is tracked, and how performance is measured. Modern GTM Engineers treat NRR (Net Revenue Retention) as a quantifiable lever — not just a concept — building automation and reporting that makes it visible and actionable.
