Measure it in two currencies
Logo churn counts customers lost; revenue churn counts money lost. A company losing many small accounts while keeping large ones has high logo churn and low revenue churn, which is survivable. The reverse is a fire. Report both, monthly, as a percentage of the starting base.
Benchmarks
Healthy SMB-focused SaaS lives with 3 to 5 percent monthly logo churn; mid-market should be under 2 percent; enterprise under 1 percent. Net revenue retention above 100 percent, meaning expansion outruns churn, is the single strongest predictor of durable growth.
The levers that work
Onboarding beats win-back: the churn decision is usually made in the first two weeks. Instrument your activation moment, the action after which users rarely leave, and drive every new account to it. Annual plans reduce churn mechanically. Exit interviews find the fixable 30 percent: wrong expectations, missing integration, no champion after a job change.
FAQ
What is a good net revenue retention?
Above 100 percent is good, above 110 percent is fundable, above 120 percent is exceptional.
Is involuntary churn worth fixing?
Yes, first. Failed payments cause 20 to 40 percent of churn in self-serve SaaS and a dunning flow fixes most of it in a week.
How do I churn-proof enterprise accounts?
Multi-thread relationships. Accounts with one champion churn when that person leaves; accounts with three stakeholders rarely do.
