Gross Revenue Retention (GRR)
The percentage of recurring revenue retained from existing customers excluding any expansion revenue. GRR isolates your ability to keep customers from downgrading or churning.
What Is Gross Revenue Retention?
Gross Revenue Retention (GRR) measures the percentage of recurring revenue retained from existing customers over a period, excluding any expansion revenue. It isolates your ability to prevent downgrades and churn from your existing base. Unlike net revenue retention, GRR cannot exceed 100%.
How to Calculate GRR
GRR = (Starting MRR - Contraction MRR - Churned MRR) / Starting MRR x 100
Start with your MRR at the beginning of the period. Subtract revenue lost to downgrades (contraction) and cancellations (churn). Divide by starting MRR. Expansion revenue is deliberately excluded — that is what makes GRR different from NRR.
GRR Benchmarks for SaaS
Best-in-class SaaS companies maintain GRR above 90%. Enterprise SaaS typically achieves 95%+ GRR due to longer contracts and higher switching costs. SMB-focused SaaS may see 80-90% GRR. A GRR below 80% is a red flag that signals significant revenue leakage from your existing customer base.
