Mastering SaaS Retention: Logo Churn vs. Net Revenue Churn
Customer and revenue churn are the ultimate growth limiters for subscription and SaaS businesses. While logo churn tracks the percentage of individual accounts that cancel, Net Revenue Churn incorporates contraction, cancellations, and the power of existing customer upgrades (expansion MRR). Negative net churn—where expansion exceeds churn—powers the fastest growing public and private SaaS companies.

Frequently Asked Questions
What is the formula for customer (logo) churn rate?
Customer Churn Rate (%) = (Customers Lost during period / Total Customers at start of period) x 100.
What is Net Revenue Churn?
Net Revenue Churn (%) = [(Churned MRR + Contraction MRR - Expansion MRR) / Starting MRR] x 100. When Expansion MRR is greater than churned and contracted revenue, Net Revenue Churn becomes negative, which is an indicator of top-tier SaaS performance.
What is considered a healthy churn rate for SaaS?
For SMB SaaS targeting small businesses, 3% to 5% monthly churn is common. For Mid-Market SaaS ($10k-$50k ACV), healthy monthly churn is 1% to 2%. For Enterprise SaaS ($100k+ ACV), top companies achieve under 0.5% monthly churn (or under 6% annually).
How does churn rate affect Customer Lifetime Value (LTV)?
LTV is inversely related to churn rate: Average Customer Lifetime = 1 / Churn Rate. For example, a 5% monthly churn rate means the average customer stays for 20 months (1 / 0.05). Halving churn to 2.5% doubles average customer lifetime to 40 months.
