Logo Churn Calculator

Logo churn is customer-count churn only. It ignores revenue expansion and customer size.

Logo churn is customer-count churn only. It ignores revenue expansion, upgrades, and downgrades, so it should not be confused with revenue churn or NRR.

How to use this Logo Churn Calculator

Enter your current SaaS metrics, then review the result, secondary metrics, and benchmark interpretation. This calculator is designed for fast planning rather than formal accounting.

Formula

Logo Churn = Lost Customers ÷ Customers at Start × 100

The important point is consistency. Use the same revenue definition, time period, and customer definition every time so the metric remains comparable month to month.

Benchmark notes are directional. A healthy metric can still hide poor cohort quality, weak cash flow, or low gross margin.

Logo churn limitation

Logo churn only counts customers lost. It ignores revenue size, so losing one enterprise customer and one tiny customer may look the same even when the revenue impact is very different.

Logo churn clarification

Customer count only: logo churn ignores revenue expansion and contraction. It measures how many customer accounts were lost, not how much revenue was retained.
