These are estimates from category benchmarks. The real number depends on where your churn actually splits, how your billing retries behave, and what your lifecycle coverage looks like today. We verify all three in a two-page current-state read — built from your public funnel and a short conversation, at no cost.

Methodology: failed-payment losses = members × monthly churn × failed-payment share × monthly revenue per member × 12. Recovery, winback, and lifecycle ranges reflect results observed in membership and subscription businesses FUTURE MKT has worked with, including multi-location consumer services chains. Estimates are directional and intentionally conservative; they are not a guarantee of results.
