Definition
NRR, net revenue retention, measures how the recurring revenue from a fixed group of existing customers changes over a period, usually a year, after adding expansion from upgrades and subtracting losses from downgrades and cancellations. The formula in words is starting recurring revenue from a cohort, plus expansion, minus contraction, minus churn, divided by starting recurring revenue. An NRR of 110% means last year's customers are worth 10% more today even if no new customer was signed.
In a company, NRR is the clearest measure of whether customers grow with you. It is driven by pricing that scales with usage or seats, a product that spreads across departments, and customer success teams focused on expansion rather than just renewal. Investors treat NRR as a core valuation driver: a company with 120% NRR compounds from its existing base and can grow even when new sales slow down. A company at 90% must replace a tenth of its revenue every year just to stand still.
Benchmarks published for 2026 put median SaaS NRR around 102%, with top-quartile companies at 110% or above. Enterprise-focused companies with large contracts reach a median around 118%, while small business segments often sit just below 100%. Usage-based pricing tends to produce higher NRR than seat-based pricing. The misconception is that NRR alone tells the story: a company can post high NRR by expanding a few accounts while quietly losing many small customers, so it should always be read alongside gross revenue retention, which ignores expansion.
In practice
A cohort of customers paid €1 million in ARR a year ago. Since then, upgrades added €200,000, downgrades removed €50,000 and cancellations removed €80,000. The cohort is now worth €1.07 million, an NRR of 107%: the company grew 7% before signing a single new customer.
Why it matters
NRR is the metric that separates companies that must run to stand still from companies that grow in their sleep. In the companies I run, it is the number I use to judge whether the product and pricing are working, because it cannot be bought with a bigger marketing budget.
Frequently asked questions
- What is a good net revenue retention rate?
- Above 100% means existing customers grow in value over time. Around 102% is the median for SaaS in 2026 benchmarks, 110% or more is top quartile, and enterprise-focused companies often exceed 115%. Below 100% means you must replace lost revenue with new sales before growing at all.
- What is the difference between NRR and GRR?
- Gross revenue retention (GRR) measures revenue kept from existing customers after churn and downgrades, with no credit for upgrades, so it can never exceed 100%. Net revenue retention (NRR) adds expansion revenue on top, so it can exceed 100%. GRR shows how well you keep customers; NRR shows how well you grow them.
