Churn Rate

A practical example

Example: a SaaS vendor with 200 customers loses 12 in a quarter, giving 6% quarterly logo churn; if the lost accounts were mostly small plans, revenue churn could be lower, which changes the retention story.

What to evaluate before investing

• Confirm whether a tool computes churn from your CRM or billing data of record, and how it handles mid-period upgrades, downgrades and paused subscriptions.
• Check that churn can be segmented by cohort, plan, segment or acquisition channel, since blended averages hide problem segments.
• Ask how the vendor defines the churn window and whether the metric is auditable, with a traceable calculation you can reproduce.

Limitations and tradeoffs

Churn is a lagging indicator: it tells you retention already happened, not why, so pair it with exit interviews and usage data before drawing conclusions or changing spend.
