Frequently Asked Questions

Everything you need to know about Net Revenue Retention and how to use this calculator.

Net Revenue Retention (NRR) is a critical SaaS metric that measures the percentage of recurring revenue retained from existing customers over a specific period, including expansions, upgrades, downgrades, and churn. It shows whether your business is growing or declining from your current customer base alone, without factoring in new customer acquisition.
NRR is one of the most important health indicators for subscription-based businesses. A high NRR (above 100%) means your existing customers are spending more over time through upsells and expansions, indicating strong product-market fit and customer satisfaction. It's a key metric that investors look at when evaluating SaaS companies, as it demonstrates sustainable growth potential.
NRR is calculated using this formula: NRR = ((Starting MRR + Expansion Revenue − Churned Revenue − Contraction Revenue) / Starting MRR) × 100. For example, if you start with $100,000 MRR, gain $15,000 from expansions, and lose $10,000 from churn and downgrades, your NRR would be 105%, meaning you grew your revenue from existing customers by 5%.
For SaaS companies, an NRR above 100% is considered good. Top-performing SaaS companies typically achieve NRR rates of 120% or higher. An NRR between 90–100% is acceptable but suggests room for improvement. Below 90% indicates significant customer retention challenges that need immediate attention.
NRR is essential for any subscription-based or recurring revenue business model, including SaaS companies, membership sites, subscription box services, and businesses with annual contracts. It's particularly valuable for B2B SaaS companies where upsells and expansions are common.
