What is Logo Churn?

Logo Churn is the percentage of customer accounts lost in a given period, counted by number of accounts regardless of their size or revenue. It is distinct from revenue churn, which weights lost accounts by how much revenue they represented.

TL;DR

Logo churn simply counts how many customer accounts walked away, treating a tiny account and a huge one exactly the same.

Formula

Logo Churn = (Accounts Lost / Total Accounts at Start of Period) × 100

Why It Matters

Logo churn tells a different story than revenue churn, and the gap between the two is often more informative than either number alone. A company can have low revenue churn while losing a large number of small accounts, which is a sign the product isn't sticking with smaller customers even if the bigger accounts are healthy, a pattern revenue churn would completely mask. It's also a leading indicator of broader product-market fit issues, since losing many logos regardless of size suggests something structural about onboarding, value delivery, or fit rather than just a few large accounts having unique circumstances. Investors and boards frequently want both numbers side by side precisely because they can diverge so sharply, revenue churn can look reassuring while logo churn quietly signals a retention problem building beneath the surface. Ignoring logo churn in favor of revenue churn alone risks missing early warning signs until they eventually show up as a revenue problem too.

Example

A company starts the quarter with 500 customer accounts and loses 20 of them. Logo churn is 20 divided by 500, times 100, which equals 4%. If those 20 lost accounts were all small customers representing only 1% of total revenue, the company could have a low revenue churn rate despite this same 4% logo churn, which is why the two metrics are tracked separately, since losing many small accounts and losing a few large ones tell very different stories about product-market fit.

Frequently Asked Questions

  • Any customer account that cancels or doesn't renew during the period, counted as one lost account regardless of whether it was the company's smallest or largest customer.

  • Logo churn counts lost accounts by number, treating every account equally. Revenue churn weights lost accounts by how much revenue they represented, so losing one large account can move revenue churn a lot while barely moving logo churn.

  • It varies by customer segment and contract length, businesses serving smaller customers on shorter contracts typically tolerate higher logo churn than enterprise-focused businesses with long-term contracts, so the right benchmark depends on who a company sells to.

  • This happens when the accounts being lost differ in size from the accounts being retained, for example losing many small accounts while keeping large ones intact produces high logo churn alongside low revenue churn.

  • By improving onboarding and time-to-value for smaller or newer accounts, since logo churn concentrated among smaller customers often points to a gap in how quickly they experience the product's core value.
