How to use this calculator
Enter beginning MRR from existing customers, downgraded MRR, churned MRR, and your target GRR.
Expansion revenue is intentionally excluded because GRR measures pure revenue preservation.
Calculate Gross Revenue Retention for SaaS without counting expansion revenue. This GRR calculator shows how much existing recurring revenue remains after churn and downgrades, revealing core retention quality.
Enter beginning MRR from existing customers, downgraded MRR, churned MRR, and your target GRR.
Expansion revenue is intentionally excluded because GRR measures pure revenue preservation.
GRR shows how much recurring revenue remains before upsells or expansion. Strong GRR means the product keeps revenue even without upgrade activity.
GRR cannot exceed 100% because expansion revenue is excluded.
With $100,000 beginning MRR, $7,000 downgrades, and $4,000 churn, retained revenue is $89,000 and GRR is 89%.
Subtract downgraded and churned MRR from beginning MRR, then divide by beginning MRR.
Many SaaS teams view 90%+ GRR as healthy, while higher enterprise-focused SaaS businesses may target even stronger retention.
No. GRR excludes expansion revenue so it can measure revenue retained before upsells.
GRR excludes expansion revenue, while NRR includes expansion. That is why NRR can be higher than GRR.
Revenue leakage is the combined downgraded and churned MRR. The calculator compares it with beginning MRR and target GRR.
