Logo churn (or customer account churn) measures the percentage of total customer accounts or business entities that cancel their subscriptions during a specific time period.

Logo Churn Rate % = (Lost Customers / Starting Customers) × 100.
How do you calculate Annualized Logo Churn from a monthly rate?
Annualized Logo Churn % = [1 − (1 − Monthly Churn Rate)^12] × 100.
What is a good monthly Logo Churn rate for B2B SaaS?
For Enterprise B2B SaaS, monthly logo churn should be under 0.5%–1.0% (5%–10% annually). For SMB SaaS, 1.5%–3.0% per month is typical.
Why is high Logo Churn dangerous even if Revenue Churn is low?
High logo churn depletes your total addressable market (TAM), reduces referral network effects, and indicates poor product usability or weak onboarding.
Does Logo Churn include customer upgrades or downgrades?
No. Account tier upgrades or downgrades affect revenue churn, but do not change logo churn unless the customer completely cancels.
