Gross Revenue Retention (GRR) Calculator
Enter starting ARR, downgrade ARR, and churned ARR to calculate GRR (Gross Revenue Retention) — a "gross" retention rate that excludes expansion revenue from upsells and cross-sells. Includes a benchmark table capped at 100%.
GRR benchmark reference table
| Tier | GRR range | Meaning |
|---|---|---|
| Excellent | 95% or higher | Losses from churn and downgrades are minimal — the existing customer base is essentially fully retained |
| Good | 90%–94% | A healthy level where losses from churn and downgrades are kept small |
| Fair | 80%–89% | The existing customer base is shrinking somewhat — there is room to improve |
| Poor | Below 80% | Churn and downgrades urgently need to be addressed |
What counts as a healthy GRR varies by business model and customer segment (enterprise vs. self-serve, for example). Treat these ranges as general guidance only.
Usage tips
- GRR never includes expansion ARR from upsells or cross-sells. If you also want to factor in your customer base's expansion power, pair this with our NRR calculator.
- GRR is always capped at 100%, so it can never exceed that value — unlike NRR, there is no equivalent to "negative churn" here.
- You can calculate GRR over any period, but when comparing it against NRR, make sure to use the same period for both.
- If your GRR is low, check separately whether downgrades or churn are the bigger driver — that makes it easier to prioritize customer-success initiatives.
Frequently asked questions
Side Note — Why GRR and NRR are usually discussed together
Gross Revenue Retention (GRR) is often mentioned alongside Net Revenue Retention (NRR) as its "baseline" companion metric that excludes expansion revenue from upsells and cross-sells. If you only look at NRR, expansion revenue can mask losses from churn and downgrades — making it easy to miss the fact that the existing customer base itself is actually shrinking.
In investor materials and due-diligence documents for SaaS companies, GRR and NRR are typically reported side by side. A low GRR paired with a high NRR can signal fragile growth propped up by a handful of large accounts expanding their spend. Conversely, a high GRR with only a small gap to NRR suggests a stable customer base that does not depend heavily on upsells.
The fact that GRR is always capped at 100% mirrors the accounting idea of a "yield" or "retention rate" — it excludes all offense-side gains from new acquisition and upsells, measuring only how well an existing asset (the customer base) was protected from erosion. That design makes it a clean, standalone gauge of a business's defensive strength.
