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:

  1. Enter starting MRR.
  2. Input churn and contraction revenue.
  3. 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.

Frequently Asked Questions

What is a good gross revenue retention rate?
A good GRR is above 90%, with top SaaS companies achieving 95% or higher.
What's a good GRR for a SaaS company?
Best-in-class SaaS businesses typically post gross revenue retention above 90%. GRR between 80-90% is common and acceptable for many segments, especially SMB-focused products, while below 80% usually signals a real churn or product-fit problem.
Why can't GRR exceed 100%?
By definition, GRR only subtracts revenue lost to churn and downgrades from your starting MRR — it never adds anything back, including upsells or expansion revenue. The maximum possible outcome is retaining exactly 100% of what you started with.
What's the difference between churn and contraction in this calculation?
Churn is revenue lost when a customer cancels entirely. Contraction is revenue lost when an existing customer downgrades to a cheaper plan or reduces usage but doesn't fully cancel — both count against GRR, but they often need different fixes.
Does GRR vary a lot by customer segment?
Yes, significantly — enterprise customers typically show much higher GRR (95%+) due to longer contracts and higher switching costs, while SMB or self-serve segments often see lower GRR (80-85%) due to easier cancellation and higher price sensitivity.
How is GRR different from customer retention rate?
Customer retention rate counts the percentage of customers you kept, regardless of revenue size. GRR is revenue-weighted — losing one large customer affects GRR more than losing several small ones, which often better reflects real business impact.
Should I calculate GRR monthly or annually?
Both have uses — monthly GRR helps you spot problems quickly, while annual GRR smooths out seasonal noise and is the number most commonly reported to investors and used for year-over-year comparisons.
