According to the PLG AI SaaS Benchmarks 2026 report, SaaS companies lose an average of 5–7% of revenue every month to churn, a rate that quietly compounds into nearly half of annual revenue erosion if left unchecked.
Most teams don’t realize churn is already happening long before the cancellation click. It starts as subtle behavioral drift, lower engagement, feature abandonment, and delayed logins and only shows up in dashboards when it’s too late to act.
