Customer Churn Rate, Retention Rate & Net Revenue Retention (NRR

SaaS Valuation & Subscription Unit Economics: Logo vs. Revenue Churn

Customer retention is the primary determinant of compound valuation multiples in subscription businesses:

• Logo Churn vs. Net Revenue Churn (NRR):

• Logo Churn: Measures the raw percentage of customer accounts lost (e.g. 2% per month).

• NRR (Net Revenue Retention): Measures total revenue retained from an existing cohort including upgrades, cross-sells, and tier expansions. An NRR above 100% indicates "Negative Net Churn," meaning the company would continue growing even with zero new customer acquisition.

• The Leaky Bucket Compounding Trap: A monthly logo churn of 5% may seem modest, but it compounds to 46% annual customer attrition—requiring the sales team to replace nearly half the customer base every 12 months just to stay flat.

• Public SaaS Benchmarks: Top-decile enterprise software companies (Snowflake, Datadog, CrowdStrike) maintain NRR between 120% and 135% with Gross Revenue Retention above 95%.
