Gross Revenue Retention (GRR)
The percentage of recurring revenue retained from an existing customer cohort excluding expansion — a pure measure of how much of your base you are losing.
What Is Gross Revenue Retention (GRR)?
Gross Revenue Retention measures the MRR/ARR retained from a cohort excluding expansion. It includes churn and downgrades but never exceeds 100%. GRR answers the question: "How much recurring revenue from the starting cohort remained, before expansion?"
Also Known As
- Finance teams: gross dollar retention (GDR)
- Investor view: base retention rate
- CS teams: retained revenue percentage
- Board reports: GRR, downside retention
How It Works
Illustrative example: Starting MRR from a January cohort is $100K. Twelve months later, $18K has churned and $4K has contracted; expansion is ignored. GRR = ($100K - $18K - $4K) / $100K = 78%. The cohort retained 78% of starting recurring revenue before expansion. If NRR is 110% while GRR is 78%, expansion is offsetting meaningful churn and contraction, which warrants examining both components.
Best Practices
- Do track GRR alongside NRR. The gap between them shows how dependent your growth is on expansion vs stability.
- Do segment GRR by plan and customer segment. Compare it with your own historical cohorts and genuinely comparable businesses.
- Do exit-interview customers who caused contraction churn. They're still customers, so you can actually learn from them.
- Don't hide weak GRR behind a strong NRR headline. Investors will dig and find it.
- Don't treat GRR and churn as the same. GRR is dollars; churn is often logos.
Common Mistakes
- Confusing GRR with customer retention rate. GRR is revenue-weighted; customer retention is logo-weighted.
- Including new logos acquired in the period. GRR is a same-cohort metric — new logos don't count.
Industry Context
GRR is sensitive to customer segment, contract length, pricing, and measurement period. B2B services often track renewal rate, while ecommerce businesses generally use repeat-purchase or customer-retention measures rather than recurring-revenue retention.
The Behavioral Science Connection
GRR describes retained recurring revenue; it does not reveal whether customers stayed because of satisfaction, contracts, switching costs, workflow embedding, or limited alternatives. Those mechanisms require separate evidence.
Key Takeaway
NRR gets the investor headlines; GRR tells you whether your house has termites. Report both, and be suspicious of any company that shows strong NRR without also showing strong GRR.
