What is GRR (Gross Revenue Retention)? (Definition + SaaS example)
Gross Revenue Retention (GRR) measures the percentage of recurring revenue retained from existing customers over a period, excluding any expansion revenue. GRR can never exceed 100% and reflects the core stickiness of a SaaS product — how much revenue stays without upsells compensating for losses.
Formula and Calculation
Gross Revenue Retention
GRR = ((Starting MRR − Contraction MRR − Churned MRR) ÷ Starting MRR) × 100
Equivalently, using annual figures:
Annual GRR
GRR = (Beginning ARR − Contraction − Churned ARR) ÷ Beginning ARR × 100
Worked SaaS Example
A mid-market SaaS company starts Q1 with $500,000 MRR across 120 enterprise customers:
| Component | Amount |
|---|---|
| Starting MRR (Jan 1) | $500,000 |
| − Contraction MRR (12 customers downgraded) | −$22,000 |
| − Churned MRR (5 customers cancelled) | −$35,000 |
| Retained MRR (excl. expansion) | $443,000 |
GRR = ($443,000 ÷ $500,000) × 100 = 88.6%
For context, this company also had $40,000 in expansion MRR, making NRR = ($443,000 + $40,000) ÷ $500,000 = 96.6%. The gap between GRR (88.6%) and NRR (96.6%) shows how much expansion compensates for underlying churn.
GRR Benchmarks by Segment
| Segment | Typical GRR | Why |
|---|---|---|
| Enterprise (ACV > $50K) | 90–97% | Long contracts, high switching costs, dedicated CSMs |
| Mid-market (ACV $10–50K) | 85–92% | Moderate switching costs, some churn expected |
| SMB (ACV < $10K) | 75–88% | Higher churn, self-serve, price-sensitive buyers |
GRR vs NRR
Track both metrics together. A wide gap between GRR and NRR (e.g., 75% GRR vs 115% NRR) signals that expansion is masking serious retention problems — a pattern that breaks down as the customer base matures and upsell headroom shrinks.
Why GRR Matters for SaaS
Finance teams use GRR to understand the baseline health of the customer base without the optimistic lens of expansion. It answers a critical question: if the company stopped all upselling tomorrow, how much revenue would remain? This makes GRR the most conservative and honest retention metric.
In investor reporting, GRR separates companies with genuinely sticky products from those that rely on aggressive upsells to mask churn. Investors increasingly ask for both GRR and NRR because the gap between them tells a story that neither metric tells alone.
A common mistake is focusing exclusively on NRR and ignoring GRR. A company with 130% NRR and 70% GRR is losing nearly a third of its existing revenue annually and compensating through expansion. This works until the customer base saturates and upsell opportunities dry up.
GRR connects directly to NRR — together they form the complete retention picture. GRR also feeds into churn rate analysis and is a key input when forecasting ARR growth under conservative scenarios.

Frequently Asked Questions
Enterprise SaaS companies typically target GRR above 90%, with best-in-class companies achieving 95%+. SMB-focused SaaS companies often see GRR in the 80–90% range due to higher churn. A GRR below 80% signals significant product or market fit issues.

NRR (Net Revenue Retention)
Net Revenue Retention (NRR) measures the percentage of recurring revenue retained from existing customers over a period, including expansion, contraction, and churn. An NRR above 100% means a SaaS company is growing revenue from its existing customer base without acquiring a single new customer.
MRR (Monthly Recurring Revenue)
Monthly Recurring Revenue (MRR) is the predictable revenue a SaaS company earns each month from active subscriptions. MRR normalizes different billing periods — annual, quarterly, and monthly — into one consistent monthly figure, making it the foundational metric for SaaS financial planning.
Churn Rate
Churn rate is the percentage of customers or revenue lost over a given period. In SaaS, churn rate is the inverse of retention — a 5% monthly customer churn means the company loses 5% of its customer base each month. Reducing churn is the single most effective lever for improving LTV, NRR, and long-term revenue growth.
