Net Revenue Retention vs Starting MRR from Existing Customers
公式
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%.
计算示例
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
常见问题
What is considered good net revenue retention?
For B2B SaaS, NRR above 100% is good, above 110% is strong, and above 120% is world-class. B2C companies typically have lower NRR because consumer spending patterns are less sticky.
How does NRR differ from gross retention?
Gross retention only accounts for contraction and churn, ignoring expansion. It is always 100% or below. NRR includes expansion revenue, so it can exceed 100%. Both are valuable: gross retention shows the floor, NRR shows the full picture.
