Overview

Use this logo churn calculator to measure the percentage of customer accounts lost during a period, regardless of how much revenue each account represented. SaaS founders and customer success teams use it when account count matters as much as dollars. Enter logos churned and logos at period start; the result is logo churn rate. Compare with Revenue Churn, Churn Rate, NRR, or GRR when large accounts skew the dollar picture.

Formula

Lost logos ÷ starting logos × 100.

Example calculation

Using the default example values from the JSON seed for this tool:

Logos churned during period
18
Logos at period start
420

Result: 4.29% (Logo churn rate)

How to interpret this result

Lost customer logos ÷ starting logos for the window you measured.

Ignores revenue dollars—whale contractions can lurk quietly while counts look stable.

Label involuntary failed payments distinctly when Ops allows.

When to use this calculator

Rule of thumb

Logo churn can look calm while MRR drops fast—pair with dollar churn when big accounts move.

Terms used in this calculator

Churn rate (logo churn)
What share of the starting cohort you lost inside the timeframe you framed.

Common mistakes

  • Declaring victory on logos while MRR hemorrhages unnoticed.
  • Pooling involuntary churn with deliberate cancels when retention playbooks diverge.
  • Widening denominators versus finance’s starting cohort definition.

What to do next

Layer revenue churn, expansion MRR share, NRR or GRR when dollar stories disagree with logos.

How to improve this result

  • Split voluntary cancels from failed payments when billing data allows.
  • Interview recent churners while the trail is still warm.
  • Segment SMB vs enterprise when one side drags the blended rate.

FAQ

What is logo churn?
Logo churn is the share of customer accounts you lost in a period, measured by count—not by revenue.
How do you calculate logo churn?
Divide logos lost during the period by logos at the start of the period, then multiply by 100 for a percentage.
What is the difference between logo churn and revenue churn?
Logo churn counts accounts; revenue churn measures lost recurring dollars. A few large cancellations can move revenue churn more than logo churn.
Is logo churn more important than revenue churn?
Neither replaces the other. Logo churn shows account health; revenue churn shows dollar risk. Use both.
Should failed payments count as churned logos?
Tag involuntary churn separately when you can—the fix is often billing, not product.
