Why NRR can exceed 100%
Because NRR includes expansion revenue — upsells, cross-sells, seat growth — it can climb above 100% when expansion outpaces churn and downgrades. That's the holy grail of subscription businesses: a customer base that compounds on its own. Investors watch NRR closely as a signal of durable, efficient growth.
What support contributes
Expansion follows from customers succeeding with your product, and support is central to that success. Resolving issues fast and proactively guiding customers reduces the churn and contraction that drag NRR down, while satisfied customers are the ones who expand. Good support quietly props up NRR.
Formula
NRR % = ((Starting MRR + Expansion − Contraction − Churn) ÷ Starting MRR) × 100
Example: $100k starting MRR, +$15k expansion, −$5k contraction and churn: (($100k + $15k − $5k) ÷ $100k) × 100 = 110%.
