Gross Retention Rate vs Starting MRR
公式
How to Calculate Gross Revenue Retention
Formula
GRR = (Starting MRR - Churned MRR - Contraction MRR) / Starting MRR x 100
Gross retention strips out expansion revenue to show the floor of your retention performance. It can never exceed 100% because it only accounts for losses. GRR reveals how well your product delivers baseline value: if customers keep paying the same amount or leave, how much revenue survives? Top-tier B2B SaaS companies maintain GRR above 90%.
计算示例
A company starts with $200,000 MRR, loses $8,000 to cancellations and $4,000 to downgrades.
- 01Retained MRR = $200,000 - $8,000 - $4,000 = $188,000
- 02GRR = ($188,000 / $200,000) x 100 = 94%
- 03Total Lost = $8,000 + $4,000 = $12,000
常见问题
What is a good gross retention rate?
For B2B SaaS, GRR above 90% is good and above 95% is excellent. Enterprise SaaS should target 95%+. B2C subscription businesses typically have lower GRR, often 70-85%. Below 80% for B2B suggests serious product-market fit or competition issues.
How does GRR differ from NRR?
GRR ignores expansion revenue and maxes out at 100%. NRR includes expansion and can exceed 100%. GRR is the retention floor showing minimum revenue survival. NRR shows the complete picture including growth from existing customers.
