Net Revenue Retention Calculator
Measure how revenue from existing customers changes over a period, including expansion, contraction and churn.
Net revenue retention
What it measures
NRR takes the revenue from one cohort of customers, then measures what it became a period later once expansion, downgrades and churn are netted off. New customers are excluded.
Why it matters
NRR above 100 percent means the business grows even if sales stops. It is the strongest single signal of product value that a SaaS metric can send.
A worked example
Start with 100,000 from a cohort, add 8,000 expansion, lose 2,000 to downgrades and 4,000 to churn: 102,000 remains, so NRR is 102 percent.
How to read and improve it
Expansion is a product and pricing question more than a sales one. Usage based tiers and seat growth give NRR room to climb.
Frequently asked questions
What is a good NRR?
Above 100 percent is good, 110 and up is strong, and the best product led companies run 120 plus.
How is NRR different from gross retention?
Gross retention ignores expansion and can never exceed 100 percent. NRR includes it.
