NRR計算機（純収益維持率）

Q: What is a good NRR for a SaaS company?

Above 120% is best-in-class (top quartile of public SaaS companies). 110-120% is good. 100-110% is acceptable but indicates room for improvement in expansion revenue. Below 100% means your customer base is shrinking in value.

Q: How is NRR different from GRR?

NRR (Net Revenue Retention) includes expansion revenue from upsells and cross-sells. GRR (Gross Revenue Retention) only considers revenue lost to churn and contraction. NRR can exceed 100%, GRR never can.

Q: How do I improve NRR?

Invest in customer success, implement usage-based pricing that grows with adoption, build expansion features, reduce churn through better onboarding, and create upsell paths from free to paid tiers. Use [ChurnZero](https://churnzero.com) for customer success automation.

Q: What drives NRR above 120%?

Companies with NRR above 120% typically have land-and-expand business models, usage-based pricing, or multi-product ecosystems. Examples: Snowflake, Atlassian, Canva.

Q: Does NRR matter more than new customer acquisition?

For mature SaaS companies, NRR matters more. Improving NRR from 100% to 110% has the same growth impact as a 10% increase in new customer acquisition - but costs less to achieve.

Q: How often should I calculate NRR?

Monthly is standard. Track the trend over 6-12 months to identify whether retention dynamics are improving or degrading. [Baremetrics](https://baremetrics.com?via=saastainednumbers) automates NRR tracking.

Q: What is the difference between NRR and DBNRR?

NRR and DBNRR (Dollar-Based Net Revenue Retention) are the same metric - both measure revenue retention including expansion. Different sources use different names for the same concept.

Q: Can NRR exceed 200%?

Theoretically yes, but it's extremely rare. NRR above 150% requires aggressive land-and-expand dynamics where customers dramatically increase spend over time.

純収益維持率（NRR）を計算して、拡張とダウングレードを含む既存顧客からの収益維持率を測定します。

Net Revenue Retention (NRR) measures the percentage of recurring revenue retained from existing customers over a period, including expansion revenue from upsells and cross-sells minus churn and contraction. NRR is arguably the most important SaaS metric after MRR because it reveals whether your existing customer base is growing in value (NRR > 100%) or shrinking (NRR < 100%). Companies with NRR above 120% are considered best-in-class and can grow without adding new customers. This calculator computes NRR and gross retention to give you a complete picture of your revenue retention health.

この計算機の使い方

Enter your starting MRR, expansion MRR from upgrades, churned MRR from cancellations, and contraction MRR from downgrades.
The calculator will compute your NRR percentage.
An NRR above 100% means existing customers are growing in value; below 100% means they're shrinking..

計算式と具体例

NRR = (Starting MRR + Expansion MRR - Churned MRR - Contraction MRR) ÷ Starting MRR × 100:

Gross Retention = (Starting MRR - Churned - Contraction) ÷ Starting MRR × 100.

Example: Starting MRR = $100K, +$15K expansions, -$8K churned, -$3K contractions.

NRR = ($100K + $15K - $8K - $3K) ÷ $100K × 100 = 104%.

業界ベンチマーク

Top-quartile public SaaS companies achieve NRR above 120%. Good NRR is 110-120%. Acceptable is 100-110%. Below 100% means existing customers are shrinking in value. According to KeyBanc Capital Markets 2025 SaaS Survey, median NRR for public SaaS companies is 115%. Gross revenue retention typically ranges from 85-95% for enterprise SaaS.
