Gross revenue retention (GRR) measures the percentage of recurring revenue retained from existing customers after accounting for churn and contraction, but before expansion revenue. GRR has a maximum of 100% and shows the baseline ability to retain revenue without relying on upsells.
Formula
GRR = (Starting MRR - Contraction MRR - Churned MRR) / Starting MRR x 100In Depth
GRR isolates the retention side of the customer revenue equation by excluding expansion. This makes it a purer measure of product stickiness and customer satisfaction than NRR, which can mask underlying retention problems if expansion revenue is strong.
The formula is: GRR = (Starting MRR - Contraction MRR - Churned MRR) / Starting MRR x 100. GRR can never exceed 100% because it does not include expansion.
Best-in-class enterprise SaaS companies achieve GRR of 95%+ annually. Mid-market businesses target 90-95%. SMB-focused companies typically see 80-90%. GRR below 80% is a significant concern, as it means the company loses more than 20% of its revenue base each year before any upselling.
FP&A teams should track GRR alongside NRR because together they tell the full story. A company with 85% GRR and 120% NRR is compensating for weak retention with strong expansion — a potentially fragile position. A company with 95% GRR and 110% NRR has a healthier foundation even though the headline growth metric is lower.
For UK businesses, GRR should be monitored against contract renewal cycles. Companies with annual contracts may see lumpy GRR figures as large renewals cluster in certain months.
Real-World Example
A UK SaaS company starts Q1 with £800K MRR. During the quarter, £40K churns and £12K contracts. GRR = (£800K - £40K - £12K) / £800K = 93.5%. Expansion adds £65K. NRR = (£800K - £40K - £12K + £65K) / £800K = 101.6%. The FP&A team notes that while NRR is healthy, GRR has declined from 96% a year ago, suggesting growing retention issues that expansion currently masks.
