Retention Analyzer

Gross retention measures how much revenue you keep from existing customers, excluding any expansion (upsells, cross-sells). It can never exceed 100%. Net retention (NRR) includes expansion revenue, so it can exceed 100% — meaning existing customers are spending more over time despite some churn. A company with 85% gross retention and 120% NRR is losing 15% of customers but more than making up for it with expansion from remaining customers.

For B2B SaaS, best-in-class NRR is 120%+ (companies like Snowflake, Twilio, and Datadog have exceeded 130%). Above 110% is considered strong, 100-110% is acceptable, and below 100% means your existing customer base is shrinking — a red flag for investors. For B2C and SMB products, benchmarks are lower: 90-100% NRR is typically considered good due to naturally higher churn in those segments.

Retention has an exponential impact on LTV. If monthly churn drops from 5% to 3%, average customer lifetime jumps from 20 months to 33 months — a 65% increase in LTV from just a 2-point churn improvement. This is why investors obsess over retention: small improvements compound dramatically over time, making every customer acquisition dollar go further and improving unit economics across the entire business.

Retention is the clearest signal of product-market fit. High retention means customers are getting sustained value and would miss the product if it disappeared. For investors, strong retention (especially NRR above 100%) means the company can grow revenue even without new customers, making growth more capital-efficient and predictable. Companies with poor retention require constant, expensive customer acquisition just to maintain flat revenue — a fundamentally unsustainable model.
