At a glance
| Dimension | GRR | NRR |
|---|---|---|
| Formula | (Beginning ARR − Churn − Contraction) / Beginning ARR | (Beginning ARR + Expansion − Churn − Contraction) / Beginning ARR |
| Ceiling | 100% (expansion excluded by definition) | Uncapped (can exceed 200% in hypergrowth) |
| What it measures | Product stickiness and churn prevention | Product stickiness + expansion velocity |
| Best-in-class benchmark | > 90% (enterprise), > 85% (SMB) | > 120% (enterprise), > 110% (mid-market) |
| Median public SaaS | 87-92% (KeyBanc 2023) | 105-115% (KeyBanc 2023) |
| Investor signal | Below 80% is a red flag in Series B+ diligence | Above 120% commands premium valuation multiples |
| Team ownership | Customer Success (churn prevention) | Account Management + Expansion Sales |

When to use GRR
GRR is the primary retention health metric for CS teams focused on churn prevention. It isolates the pure retention question — are customers renewing at the price they committed to — from the expansion question. GRR below 85% in enterprise SaaS is a product-market fit signal: customers are either churning (finding insufficient value) or downgrading (value not worth the original price). Improving GRR requires investments in onboarding quality, time-to-value, and product adoption — the operational levers of Customer Success.
When to use NRR
NRR is the primary metric for measuring the expansion engine and for investor conversations about long-term business quality. NRR above 100% means the company can grow ARR from its existing customer base alone — a compounding property that makes the business fundamentally different from one that requires continuous new logo acquisition to maintain flat ARR. NRR is the metric Bessemer, Sequoia, and public market investors most closely associate with revenue multiple premium in SaaS valuations. Use NRR to communicate the quality and compounding power of your customer relationships.
Trade-offs
GRR and NRR are complementary metrics that together tell the complete retention story. Neither alone is sufficient: High NRR with low GRR is a warning sign: it means you are expanding a concentrated set of large customers while churning a high percentage of smaller ones. This creates revenue concentration risk — if the large customers churn, NRR collapses. Companies with 150% NRR but 60% GRR are often masking a serious SMB churn problem with enterprise expansion. High GRR with low NRR means you have sticky customers who are not growing. This is common in tools that serve a stable workflow without expansion vectors (fixed-seat licensing, single-use software). It is a fine business model, but it requires continuous new logo acquisition to compound ARR growth, because existing customers generate zero organic expansion. Best-in-class SaaS companies achieve both: > 90% GRR (very few customers leave) and > 120% NRR (customers who stay expand by more than 20% per year net of any downgrades). This combination — achieved by Snowflake (158% NRR at IPO), Datadog (125%+), and ZoomInfo — creates a business that compounds from the existing base while also acquiring new logos. The practical levers for improving each: GRR improves through faster time-to-value, proactive health score monitoring, and executive relationship programs. NRR improves through usage-based pricing expansion vectors, structured upsell playbooks, cross-sell motions to adjacent use cases, and expansion-focused account management with quotas.
Frequently asked questions
What are the best-in-class GRR and NRR benchmarks by segment?
KeyBanc 2023 SaaS Survey benchmarks by segment: Enterprise GRR > 90% (top quartile > 94%); Mid-market GRR > 87%; SMB GRR > 80% (high churn is structural). Enterprise NRR > 115% (top quartile > 125%); Mid-market NRR > 108%; SMB NRR > 100% (expansion often offsets SMB churn). The SMB benchmarks are more forgiving on GRR because SMB churn is partly exogenous (business failures) but expansion is harder to drive at scale.
Why is NRR above 100% so strategically significant?
When NRR exceeds 100%, the company generates positive ARR growth from existing customers without any new logo acquisition. At 120% NRR, a company with $10M ARR will grow to $12M ARR from its existing base alone — $2M in 'free' ARR requiring zero incremental CAC. Over 10 years at 120% NRR, $10M ARR compounds to $62M from the base alone, before any new logo ARR. This compounding property is why Bessemer analysis shows NRR is the single metric most correlated with long-term revenue multiple — it is geometric growth, not arithmetic.
How do I reconcile GRR and NRR in a board report?
The cleanest presentation: Starting ARR $10M → Expansion +$2M → Churn/Contraction −$1M = Ending ARR $11M. GRR = ($10M − $1M) / $10M = 90%. NRR = ($10M + $2M − $1M) / $10M = 110%. This ARR bridge makes both metrics self-evident and shows the board exactly how much of the ARR growth came from expansion vs. new logos (reported separately). Always include both metrics together — reporting only NRR without GRR allows a high-expansion company to mask a high-churn problem.
What is the difference between logo churn and revenue churn?
Logo churn rate = number of customers who cancelled / total customers at period start. Revenue churn rate = ARR churned / beginning ARR. These can diverge significantly: if 20% of customers (all small) churn, logo churn is 20% but GRR might be 90% if those customers represent only 10% of ARR. Conversely, if one large enterprise downgrades significantly, logo churn might be 0% but GRR could fall below 85%. For SaaS companies with heterogeneous customer sizes, revenue churn (GRR) is the more economically relevant metric.
How does usage-based pricing (UBP) affect NRR?
Usage-based pricing is the highest-leverage structural driver of NRR because expansion happens automatically as customers grow — no upsell motion required. Snowflake's 158% NRR at IPO was driven almost entirely by usage-based expansion as customers increased data workloads. The trade-off: UBP introduces revenue variability (customers can also contract usage in downturns), which compresses GRR. Companies like Twilio and Datadog run hybrid models — a committed base contract that protects GRR, plus usage-based overages that drive NRR above 120%.
Where this sits in the GTM World Model
GRR and NRR are the two retention inputs to the GTM World Model's Compounding Revenue Equation — GRR sets the decay floor on existing ARR while NRR sets the expansion ceiling, and the difference between them defines how much of the company's ARR growth engine is CAC-free versus requiring continued acquisition investment.
