What Is GRR? Gross Revenue Retention Explained
Gross Revenue Retention (GRR) measures the revenue retained from existing customers after accounting for churn and contraction — but excluding expansion. It can never exceed 100%. GRR is the purest measure of how well you hold onto the revenue you already have, without the positive distortion of upsells and expansion.
Quick Answer
GRR = ((MRR at Start − Churn − Contraction) ÷ MRR at Start) × 100
Healthy target: above 85%. World-class: above 90%.
Why GRR Matters
NRR can look impressive when expansion revenue masks a retention problem. A company with 120% NRR might seem healthy, but if that 120% comes from 80% GRR plus massive expansion, the underlying business is leaking 20% of its revenue base every period. When expansion inevitably slows, the true retention problem is exposed.
GRR is the metric that reveals this risk. It shows whether your product genuinely retains customers or whether growth is propped up by upselling. Investors increasingly ask for both GRR and NRR because GRR is harder to manipulate and reflects genuine product-market fit.
How to Calculate GRR
GRR Formula
GRR = ((MRR at Start − Churn − Contraction) ÷ MRR at Start) × 100
Example: Starting MRR = $40,590. Churned MRR = $1,780. Contraction MRR = $640. GRR = (($40,590 − $1,780 − $640) ÷ $40,590) × 100 = ($38,170 ÷ $40,590) × 100 = 94.0%
Note that expansion MRR is not included. This is the key difference from NRR, which would add expansion back in.
GRR vs NRR: What's the Difference?
GRR (Gross Revenue Retention)
- Excludes expansion revenue
- Can never exceed 100%
- Measures how well you prevent revenue loss
- Reveals true retention without upsell masking
- Healthy: above 85%. World-class: above 90%
NRR (Net Revenue Retention)
- Includes expansion revenue
- Can exceed 100%
- Measures whether existing customers are growing
- Reflects total revenue from existing base
- Healthy: above 110%. World-class: above 130%
A company with 90% GRR and 120% NRR is fundamentally healthier than one with 80% GRR and 120% NRR. Both have the same NRR, but the first company is losing only 10% of revenue before expansion, while the second is losing 20% and relying on aggressive upselling to compensate.
GRR Benchmarks by Stage
| Stage | GRR Target | NRR Target |
|---|---|---|
| Seed / Pre-Seed | > 80% | > 100% |
| Series A | > 82% | > 105% |
| Series B+ | > 85% | > 110% |
| Enterprise | > 90% | > 115% |
How to Improve GRR
- Reduce churn. Focus on keeping customers from cancelling entirely. This is the biggest lever for GRR improvement.
- Prevent contraction. Identify at-risk accounts before they downgrade. Monitor seat count, usage, and engagement trends.
- Improve onboarding. Customers who reach their aha moment quickly are far less likely to churn or downgrade.
- Offer mid-tier plans. Give downgraders a place to go before they cancel entirely. A mid-tier plan captures revenue that would otherwise be lost.
- Fix involuntary churn. Implement dunning sequences and card updater services to prevent payment failures from causing churn.
Common GRR Mistakes
Common Mistake
Including expansion revenue in GRR. That is NRR, not GRR. GRR should only measure losses (churn + contraction), never gains. If your GRR exceeds 100%, you are calculating NRR, not GRR.
