Involuntary churn is customers lost because a payment failed, not because they chose to leave. Type three numbers from your own books and see what it costs. The formula is on the page; nothing is guessed for you.
At a glance. For a subscription business that wants to price its failed payments. It turns your monthly recurring revenue, the share of payments that fail and the share you win back into a monthly and yearly cost. Every rate is typed by you; the one outside figure cited is a single survey. Last checked 13 November 2026.

How big is the problem? A 2023 survey of 200 subscription-business executives, reported by PYMNTS, put failed payments at about half of customer churn (read the report). That is one survey of one group; your own account is the only number that counts, and the free scan reads it. Stripe explains its automatic retries on its Smart Retries page.
In Stripe, under Billing, Revenue recovery, or by dividing the number of invoices whose first attempt failed by all invoices in a month. The free scan on this site counts the unpaid ones from your own account.
Because a default would be an invented statistic. Every number here is one you typed.
