What is Gross Revenue Retention Calculator?
The Gross Revenue Retention Calculator measures how well you retain revenue from existing customers without expansion.
When to Use This Calculator
- Measuring how much recurring revenue you keep from existing customers, independent of new sales or upsells
- Reporting a SaaS company's underlying revenue durability to investors or a board
- Comparing retention performance across customer segments, plans, or cohorts
- Diagnosing whether revenue problems come from losing customers or from new-customer acquisition slowing down
- Setting internal targets for customer success and support teams tied directly to revenue durability
- Benchmarking your retention against SaaS industry standards during fundraising or planning
Steps:
- Enter starting MRR.
- Input churn and contraction revenue.
- View GRR.
Formula
GRR = (Starting MRR − Contraction MRR − Churned MRR) ÷ Starting MRR × 100

Related Concepts
- Net Revenue Retention: NRR adds expansion revenue back into the picture, which is why it can exceed 100% even when GRR can't. Compare both with our net revenue retention calculator to see the full retention story.
- Churn Impact: GRR is driven directly by churn and contraction — see the dollar impact of your churn rate specifically with our churn impact calculator.
- SaaS Quick Ratio: Quick ratio measures growth efficiency (new + expansion versus churn + contraction) as a single ratio — a natural companion metric alongside GRR. Check it with our SaaS quick ratio calculator.
- Rule of 40: Retention feeds directly into growth rate, one half of the Rule of 40 balance between growth and profitability. See how your numbers stack up with our Rule of 40 calculator.
- LTV:CAC Ratio: Strong retention (a high GRR) directly increases customer lifetime value, which improves your LTV:CAC ratio — check that relationship with our LTV:CAC ratio calculator.
Example
With $100K starting MRR, $8K churn, $2K contraction, GRR is 90%.
Interpreting Your Results
Gross revenue retention measures how much of your starting recurring revenue you kept, counting only contraction (downgrades) and full churn as losses — it deliberately excludes expansion revenue (upsells, add-ons) from new sales to existing customers, which is why GRR can never exceed 100%. This makes it a purer measure of how "sticky" your product and customer relationships are, separate from how good your upsell motion is. Best-in-class SaaS companies typically post GRR above 90%; anything below 80% usually signals a real retention or product-fit problem that needs attention before it's worth investing more in growth. Because GRR strips out expansion, always look at it alongside net revenue retention (NRR) — a company can have strong NRR from upsells while masking a weak GRR underneath, which is a fragile position if upsell opportunities dry up.
