Net Revenue Retention vs Starting MRR from Existing Customers
How to Calculate Net Revenue Retention
Formula
NRR = (Starting MRR + Expansion - Contraction - Churn) / Starting MRR x 100
NRR measures how much your existing customer revenue grows or shrinks, excluding new customer acquisitions. An NRR above 100% means existing customers spend more over time, which is the hallmark of elite SaaS companies. Top-performing B2B SaaS businesses achieve NRR between 110% and 140%.
Example Calculation
A SaaS company starts with $100,000 MRR from existing customers. Expansions add $15,000, downgrades remove $5,000, and cancellations lose $8,000.
- 01Ending MRR = $100,000 + $15,000 - $5,000 - $8,000 = $102,000
- 02NRR = ($102,000 / $100,000) x 100 = 102%
- 03Net Change = $15,000 - $5,000 - $8,000 = +$2,000
