Net Revenue Retention
Also called NRR, Net Dollar Retention, and NDR
Net revenue retention measures how much recurring revenue you keep from existing customers over a year, including upgrades and expansion but after downgrades and churn. Above 100 percent means the base grows even with no new customers.
NRR = (starting revenue + expansion - contraction - churn) / starting revenue
Why it matters
NRR is one of the most watched SaaS metrics because it shows whether your product gets more valuable to customers over time. Best-in-class NRR above 120 percent is a growth engine on its own.
For example
A SaaS company grows revenue from its existing base by 18 percent through upsells even after churn, a net revenue retention of 118 percent.
