Gross Revenue Retention (GRR)
The percentage of recurring revenue retained from existing customers over a period, excluding expansion revenue. GRR only measures the downside — how much revenue you keep before upsells and cross-sells.
GRR Shows You the Real Health of Your Product
NRR is the metric everyone celebrates. GRR is the metric that tells you the truth. A company can have 120% NRR while losing 20% of its base, if expansion from surviving accounts is strong enough. GRR strips away the expansion mask and shows you how sticky your product actually is.
The Formula
GRR = (Beginning MRR - Contraction MRR - Churned MRR) / Beginning MRR x 100
Note what is missing: expansion. GRR can never exceed 100%. If it is 92%, you are retaining 92 cents of every dollar and losing 8 cents to churn and downgrades.
Why Investors Look at GRR
High NRR can hide bad retention when expansion is strong. Investors look at GRR to separate product-market fit from upsell motion. A company with 95% GRR and 115% NRR has strong retention AND expansion. A company with 75% GRR and 115% NRR has a leaky bucket that expansion barely fills. The first company is investable. The second needs to fix its core product.
Improving GRR
GRR improves when customers use your product deeply and cannot leave without pain. Improve onboarding to drive stickiness early. Build integrations that create switching costs. Deliver value faster so customers hit their aha moment before renewal conversations start.
Frequently Asked Questions
What is the difference between GRR and NRR?
GRR only measures losses — churn and contraction. It can never exceed 100%. NRR includes expansion revenue, so it can exceed 100%. If GRR is 85% and NRR is 120%, it means you are losing 15% of existing revenue but expansion adds 35% back and then some.
What is a good GRR for B2B SaaS?
Above 90% is good for B2B SaaS. Above 95% is excellent. Below 85% signals a retention crisis. Enterprise SaaS with annual contracts typically achieves 90-95%. SMB SaaS with monthly contracts often runs 80-90%. GRR cannot exceed 100% because it excludes expansion.
