Churn rate is the percentage of customers or revenue lost in a given period. Use this free churn rate calculator to compute logo churn (customer churn) and revenue churn (MRR or ARR churn) instantly.
Best-in-class B2B SaaS companies typically run below 1% monthly logo churn and aim for negative net revenue churn through expansion. Self-serve and SMB segments tend to see higher churn than enterprise.
DealARR tracks churn automatically across cohorts, segments, and ARR bands so you can spot churn risk before it impacts revenue.
