Gross Revenue Retention (GRR)

Gross Revenue Retention (GRR) is the floor version of Net Revenue Retention — it measures only what's kept from the existing customer base, without crediting expansion revenue. The formula is: (Starting MRR - Contraction MRR - Churn MRR) ÷ Starting MRR × 100. GRR can never exceed 100% because it intentionally excludes expansion, and a GRR of 85% means that 15% of the existing revenue base was lost through cancellations and downgrades in the measured period. Unlike NRR — which can mask high churn with aggressive expansion — GRR provides a cleaner view of the business's ability to retain what it already has.

The relationship between GRR and NRR reveals the health of the revenue motion. A business with NRR of 110% and GRR of 70% is expanding aggressively enough to offset terrible retention — a strategy that works until expansion slows, at which point the underlying churn becomes existential. A business with NRR of 105% and GRR of 98% has nearly identical customer retention and modest organic expansion, a far more durable foundation. Investors and board members increasingly ask for both numbers precisely because NRR without GRR can obscure retention problems that are being papered over by expansion ARR.

For B2B content teams, GRR is the retention report card — the metric most directly influenced by how well customers understand and adopt the product. Customers who churn or downgrade almost always cite a version of "we didn't get enough value" as the reason, which is typically a symptom of inadequate adoption rather than inadequate product. Customer onboarding video series, feature education content, and renewal-focused case studies that articulate continued ROI are the content levers most directly tied to GRR improvement. When GRR is below target, content investment in the existing base delivers faster returns than doubling down on acquisition.
