What Is Logo Churn?

A logo is a company, whatever its seat count or contract size. To calculate churn, take the customers on the books when the period opens, count how many of them cancelled or failed to renew before it closes, and divide. Customers won during the period stay out of the base. A downgrade is not a lost logo, because the account is still a customer, so that loss belongs in revenue churn instead.

For anyone selling software, logo churn explains which kinds of customers stick. A company with many small accounts and a high logo churn rate can still look healthy on revenue if its largest customers stay, which is why the metric is usually cut by segment, plan, or industry. Reps selling into a segment with poor logo retention burn pipeline on customers who leave quickly, and the segments that renew year after year are where outbound effort compounds.

Timing hides the problem. A company on annual contracts shows almost no churn for eleven months and then a cluster at renewal, so a flat monthly chart can mislead. Definitions differ too: some teams count a logo as churned when notice is given, others when access ends, and others only after a grace period. Pick one rule and keep it, or comparisons across quarters stop meaning anything.
