Net revenue retention is the metric investors check first, because it shows whether your existing customers grow on their own. Here is the plain definition, the formula and why above 100 percent changes everything.
This is the number that separates good SaaS from great. At 100 percent your existing base holds flat. At 120 percent it grows a fifth every year on its own, so new sales pile on top of a rising floor instead of refilling a leaky bucket. Below 100 percent you are running uphill, replacing lost revenue before you can grow.
The free net revenue retention calculator works it out and shows where you land against the benchmark.
Anything above 100 percent is good, since it means the base grows on its own. Best-in-class B2B SaaS runs 120 percent or higher and the strongest enterprise products clear 130. Under 100 percent is a leak and under 90 percent usually points to a product or fit problem no amount of new sales will outrun.
NRR matters more as you scale. Early on, new logos drive growth and mask retention. At size, the existing base is so large that a few points of NRR swamp anything the sales team can add. That is why investors weight it heavily, because it predicts whether growth holds when new sales slow.
Seat-based or usage-based pricing grows revenue as customers grow. Pricing that expands with value is the cleanest path past 100 percent.
Every cancellation and downgrade drags NRR down. Onboarding, support and proactive success work all protect the base you already have.
Customers who use more of the product expand and stay. Adoption is the quiet engine under high NRR, so make it the success team focus.
It is how much money you keep from the customers you already have, after they upgrade, downgrade or cancel, with no new customers counted. Above 100 percent means your existing base spends more this year than last on its own. It is the clearest sign that a product is genuinely sticky and growing inside its accounts.
Take starting recurring revenue from a cohort, add expansion, subtract churn and downgrades, then divide by the starting figure and multiply by 100. New customers are excluded on purpose, because NRR measures only the existing base. A result of 115 percent means that base grew 15 percent without a single new logo.
Above 100 percent is good and best-in-class B2B SaaS runs 120 percent or higher, with the strongest enterprise products above 130. Below 100 percent means the base is shrinking and you have to win new revenue just to stand still. Below 90 percent usually signals a fit or product problem that new sales cannot fix.
Gross revenue retention counts only what you keep, capped at 100 percent, ignoring expansion. Net revenue retention adds expansion back in, so it can exceed 100 percent. Gross retention shows how leaky the bucket is. Net retention shows whether expansion more than fills the leak, which is why net is the headline number for growth.
Because it predicts durable growth. A high NRR means revenue compounds inside the existing base, so growth holds up even when new sales slow. At scale the base dwarfs new bookings, so a few points of NRR move the whole trajectory. It is one of the strongest single predictors of a healthy SaaS valuation.
If your NRR is stuck under 100 percent, the leak is usually in onboarding and adoption, not pricing. Book a 30-minute audit and we will find it. No sales sequence.
