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.

Frequently Asked Questions
What is a good GRR?
Above 90% is strong, above 95% is best-in-class. Enterprise SaaS targets 92%+; SMB SaaS targets 80%+. Below 80% signals serious product issues that expansion revenue may be masking in NRR.
GRR vs NRR \u2014 what is the difference?
GRR excludes expansion revenue and caps at 100%. NRR includes expansion and can exceed 100%. GRR shows pure churn; NRR shows net revenue motion. Both required for full picture.
Can GRR exceed 100%?
No. By definition GRR only measures what you kept from existing revenue \u2014 never additions. If your tool shows GRR > 100% you have included expansion revenue, which is the NRR formula instead.
Should I report monthly or annual GRR?
Annual GRR is the standard for board reporting and investor diligence. Monthly GRR is useful for early-warning trend detection. Annualize monthly figures with (1 + monthly churn rate)^12 - 1 formula, not simple multiplication.
Is this tool free?
Yes. Free with no sign-up. All math runs in your browser \u2014 your revenue figures never leave your device.
