Involuntary churn: the 5–10% MRR leak nobody budgets for

Churn gets treated as one number, but it's two diseases. Voluntary churn is a customer deciding your product isn't worth it fixing that is product work. Involuntary churn is a payment failing while the customer still wants the product. Fixing that is plumbing. Plumbing is easier.

Why it stays invisible

A failed payment doesn't look like a cancellation. There's no exit survey, no angry email. The subscription just stops arriving in revenue. Unless you're splitting churn by cause, involuntary churn hides inside your blended number and quietly takes 5–10% of subscription revenue.

The three causes

• Expired cards fully predictable, fully preventable with a warning email
• Reissued cards banks replace compromised numbers; the customer often doesn't connect it to your product
• Declines insufficient funds, risk flags, issuer moods; some retry-able, some not

What a fix looks like

Measure the leak (90-day invoice audit). Turn on Stripe Smart Retries. Add human-sounding recovery emails for what retries miss. Warn before expiries. Then track recovered dollars honestly attributed on one ledger. That whole loop is what Recoupe automates for $29/mo.
