What is net revenue retention?

Net revenue retention (NRR) measures how much recurring revenue a company keeps and grows from its existing customers over a period, counting expansion, contraction, and churn, and excluding new sales. NRR above 100 percent means the installed base grows by itself before a single new customer is signed. It is the single number investors most often use to price the quality of a subscription business.

The formula, with a worked example

NRR = (starting recurring revenue from a customer cohort + expansion - contraction - churn) ÷ starting recurring revenue, over the same cohort.

Example: customers who paid $100,000 a year ago now pay $92,000 from the accounts that stayed, after $15,000 of expansion, $8,000 of contraction, and $15,000 of churned accounts. NRR = (100,000 + 15,000 - 8,000 - 15,000) ÷ 100,000 = 92 percent. The same book with $25,000 of expansion would land at 102 percent: the base now funds its own growth.

Gross revenue retention (GRR) is the same calculation with expansion excluded, capped at 100 percent. GRR isolates how much revenue survives; NRR adds how much it grows. Read together: high NRR on weak GRR means a few expanding accounts are papering over a churn problem.

Benchmarks

Reference points from the SaaS investor and operator canon, including David Skok’s metrics work and Lenny Rachitsky’s operator surveys: around 100 percent is good and 110 percent or more is strong for products sold to smaller businesses; around 110 percent is good and 120 percent or more is strong in the enterprise. The strongest public software companies have reported NRR well above 120 percent, with rare outliers higher still: Snowflake’s reported figure near 170 percent around its 2020 listing remains the number most often cited as the category ceiling.

How NRR is actually improved

Four levers, in rough order of power. Price the value metric: when price scales along the same axis as the customer’s received value (seats, usage, revenue processed), customers expand as they succeed, which is the structural source of NRR above 100. Build expansion paths into the product: tiers, add-ons, and usage room that growing customers naturally cross into. Reduce churn at its causes, which the cohort table locates. And fix contraction, the quiet leak: downgrades usually trace to unused seats and mispackaged tiers, both findable.

Frequently asked questions

What is a good NRR for SaaS?

Around 100 percent is good and 110 plus is strong for SMB products; around 110 is good and 120 plus is strong for enterprise, per the commonly cited SaaS benchmarks. Below 90 percent, the base is shrinking faster than most acquisition can refill it.

What is the difference between NRR and GRR?

GRR excludes expansion and is capped at 100 percent; it measures pure survival of revenue. NRR includes expansion; it measures survival plus growth. Both are read on the same customer cohort over the same period.

Why do investors care so much about NRR?

Because it compounds before any sales cost is spent. A company at 115 percent NRR grows 15 percent a year with zero new customers, so every euro of acquisition lands on a rising base. The difference between 95 and 115 compounds into entirely different companies within a few years.

NRR is monetization and retention measured in one number, which is why it sits at the center of the audit’s Revenue and Monetization dimension.
