Every month some of your customers' cards reach their expiry date, and the next charge fails unless the card was updated first. Type your numbers and see the monthly revenue riding on them. The free scan counts the exact figure from your own Stripe.
At a glance. For a subscription business that wants to size the revenue behind cards about to expire. It multiplies the subscribers, the average monthly price and the share of cards expiring, and prints the formula. The share is a number you type; there is no default. Last checked 13 November 2026.
Fill in the boxes above and the answer appears here.
Know exactly which cards, before the charge fails.
Do not guess: the free revenue scan counts these three numbers from your own Stripe account, with a read-only key you paste once and we forget. FoxPlug then keeps watching them and writes the notes to send; sending is on the paid plans.
Start freeA card works through the last day of its expiry month, so a card shown as 11/26 still pays on 30 November 2026. If your cards were replaced evenly over a validity period of V months, the share expiring in the next two months would be about 2 divided by V; that is an assumption to help you estimate, not a measured fact, which is why the share box is yours to fill. The free scan counts the real figure from your subscriptions.
Card networks sometimes refresh an expiring card on their own; this page ignores that, so treat the result as the revenue that depends on cards about to expire, not the revenue you will lose.
No. It is the monthly revenue that depends on cards about to expire. Some are updated by the card network or by the customer first; the what-if lines show a few shares of it.
The free scan counts cards that expire within 60 days from your Stripe account. Without it, estimate from how long your customers typically keep a card.
