How much is payment infrastructure
costing your subscription business?

Your billing dashboard has these numbers. This calculator decomposes the cost of payment-caused churn, the LTV compression it creates, and the dollar value you'd recover by eliminating it.

Cumulative revenue gap: Each month, we project two cohorts forward from 8,418 starting customers: one churning at 5.5% (all causes) and one at 3.50% (voluntary only, removing the 2.00% infrastructure component). The gap = (stablecoin cohort customers − card cohort customers) × $99 ARPU, summed monthly over 60 months. By month 60, the stablecoin cohort retains 993 customers vs. 283 on card rails — a difference of 710 customers generating $70K/mo more revenue. The 60-month sum of these monthly gaps = $6.4M.
EV derivation: Revenue gap at month 60 ($70K/mo × 12 = $844K/yr) + annual fee savings ($170K) = $1.0M/yr incremental run-rate × 8x multiple = $8.1M.
What is payment-caused churn?

Credit cards expire, banks decline legitimate charges, and processors return cryptic error codes. On average, 30-50% of customers who hit a payment failure never come back, even with state-of-the-art retry logic. These are customers who never clicked cancel. The billing system did it for them. Stablecoin-based subscriptions (now supported by Stripe) eliminate these failure modes entirely: no expiring credentials, no intermediary declines, no retry windows. The only failure mode is insufficient balance.
