Example: If you start with $10,000 of MRR, add $1,500 from upgrades, lose $300 from downgrades and $500 from cancellations, NRR = ($10,000 + $1,500 − $300 − $500) ÷ $10,000 = 107%.
Why Net Revenue Retention (NRR) matters
NRR shows whether your existing customers are growing or shrinking in value. Above 100% means you grow even without winning a single new customer, because upgrades outweigh cancellations and downgrades.
It is a strong sign of product value and a cheap source of growth, since expanding existing accounts costs less than finding new ones.
How to read it
The key line is 100%. Above it, your existing base is growing; below it, it is shrinking and new sales must cover the gap. Typical levels depend on your customer size and pricing model, so compare with your own history.
Use a consistent period, usually 12 months, and the same customer group at the start and end.
How to improve it
- Reduce cancellations with better onboarding and support.
- Create upgrade paths, add-ons and extra seats for growing customers.
- Move customers to annual plans to improve retention.
- Identify the customers most likely to expand and focus on them.
Common mistakes
- Including revenue from new customers in the calculation.
- Mixing time periods or customer groups at the start and end.
- Looking only at the total and not at which plans expand or shrink.
- Confusing NRR with gross revenue retention, which ignores upgrades.
