Gross Revenue Retention Calculator
Calculate Gross Revenue Retention (GRR) in seconds — the SaaS metric that strips out expansion revenue to show pure churn-only retention. VCs use GRR alongside NRR to spot churn problems hidden by upsells.
What Is Gross Revenue Retention?
Gross Revenue Retention (GRR) measures how much of last period's recurring revenue you kept this period, excluding all expansion. Unlike Net Revenue Retention (NRR), GRR cannot exceed 100%. It is a pure churn metric — downgrades and cancellations only. A GRR of 90% means you lost 10% of last year's revenue from existing customers, even though expansion may push NRR above 100%.
GRR Formula
GRR = (Starting MRR − Churn MRR − Contraction MRR) ÷ Starting MRR × 100. Note: do NOT subtract new customer MRR or expansion MRR. GRR is strictly about retaining what you already had at period start. Many SaaS founders accidentally include expansion and produce inflated numbers — VCs catch this in diligence.
GRR Benchmarks by Segment
OpenView 2024 SaaS benchmarks: SMB SaaS GRR median = 80%, top quartile 88%. Mid-market SaaS GRR median = 88%, top quartile 92%. Enterprise SaaS GRR median = 92%, top quartile 96%. Below 80% GRR signals product-market-fit issues regardless of growth. Top public SaaS companies (Veeva, Atlassian) maintain GRR above 95%.
GRR vs NRR — Why You Need Both
NRR can look healthy (110%+) while GRR is collapsing (75%) — expansion masks churn. Investors review both side-by-side. If NRR > 110% but GRR < 85%, you have a leaky bucket: you are paying CAC to acquire customers who quickly leave, only saved by upsells to a shrinking base. Fix the leak before scaling go-to-market spend.
