What is Net Revenue Retention (NRR)?

Short answer: The percentage of recurring revenue retained from an existing customer cohort over a period, including expansions, contractions, and churn.

Definition

The percentage of recurring revenue retained from an existing customer cohort over a period, including expansions, contractions, and churn.

Why it matters for growth

NRR above 100% means the existing customer base is growing revenue on its own, which is one of the strongest signals of durable product value.

Example

A company starts the year with $1M in ARR from its existing customers and ends with $1.15M from that same cohort, an NRR of 115%.
