How this calculator works
This gross revenue retention calculator is designed for SaaS, subscription, and recurring-revenue businesses. Enter your current operating numbers to get a fast directional result.
GRR = (starting MRR − contraction − churn) ÷ starting MRR × 100
Keep the reporting period consistent. Monthly metrics should use monthly revenue, monthly churn, and monthly acquisition counts.
How to use it
- Use clean finance or analytics data from the same period.
- Exclude one-time revenue when calculating recurring revenue metrics.
- Compare the result against prior months to see trend direction, not just one snapshot.
Result interpretation
GRR excludes expansion revenue, so it measures defensive retention. It answers whether the existing book of business is leaking before upsells are counted.
GRR benchmark
Retained Revenue: GRR focuses on revenue kept from existing customers before expansion. 95%+ is excellent, 90%–94% is good, and below 90% usually signals retention pressure.
