Card expiry is silent until the charge fails.
2–3% of your subscriber cards expire every month. Without proactive alerts, 38% of those fail their next charge — quietly. This calculates how many are in the window right now.
Card Expiry Risk Estimator · Free
Card expiry is silent involuntary churn. It happens before the payment fails. By the time it shows up in your dunning failure rate, the charge has already declined with an expired_card error. Enter your subscriber count and see exactly how many cards are entering the expiry window — and what that means for your MRR.

Without Card Health Monitoring
Card expires silently
Customer has no idea. Their card expiry date passes with no notification from you.
Charge fires — declines
Next billing date arrives. Stripe returns expired_card. Subscription lapses.
Reactive dunning begins
You send a "payment failed, please update your card" email. Customer is already gone from access.
38% never recover
Most recover eventually, but some churn for good. You find out in the failure rate next month.
With Recurflux Card Health Monitoring
Day −30: first alert
Recurflux detects the expiring card and sends a branded email from your domain prompting update.
Day −15: second alert
Customers who haven't updated yet receive a reminder with a direct payment update link.
Day −7: final nudge
Last reminder. By now, 85%+ of customers have updated proactively.
Billing day: charge succeeds
Card has been updated. No failure. No access interruption. No dunning sequence needed.
Stripe Card Account Updater covers 40–60% of expiring cards automatically. The remaining 40–60% require the customer to manually update — which only happens if you alert them proactively. Card Health Monitoring targets that gap. To see the full picture of how much all payment failures are costing you, use the Failed Payment Calculator.
Card expiry, by the numbers
Card expiry, by the numbers
Three numbers get you there: total active subscribers, average MRR per subscriber, and average subscription age. Multiply your subscriber count by the ~2.8% monthly card-expiry rate, adjust for age (older subscriber bases have done more card cycling and run hotter), and you have a rough count of cards entering the expiry window each month. Of those, roughly 38% fail their next charge with no warning — multiply that by your ARPU and you have a monthly MRR-at-risk figure. The estimator above runs that exact chain against your numbers and breaks it down across the 30/60/90-day windows that matter for planning.
Exposure scales close to linearly with subscriber count, which is exactly why it stays invisible at small scale and becomes a real number once a business grows. At 200 subscribers and $79 ARPU, expiring-card failures run somewhere in the low hundreds of dollars a month — easy to miss inside normal churn. At 1,000 subscribers, that same rate compounds into thousands of dollars a month, and at 5,000+ it becomes one of the largest single sources of involuntary churn on the books. The subscription-age modifier in the estimator captures the other half of this — a six-month-old base and a three-year-old base see meaningfully different expiry rates even at identical subscriber counts.
Most payment failures happen for reasons you can't see coming — a bank fraud flag, a temporary balance issue, an issuer-side decline that has nothing to do with the card itself. Card expiry is different: the date is printed on the card, known months in advance, and identical for every subscriber who has it. There's no guesswork, no retry timing to optimize, no decline code to interpret — just a calendar date and a chance to reach the customer before it arrives. That predictability is what makes proactive alerting so much more effective here than anywhere else in payment recovery: it turns a future failure into a routine update, before the failure ever has a chance to happen.
Reactive dunning starts after the charge has already declined — the subscription is already at risk, the customer is already annoyed, and you're working against a clock. Proactive monitoring moves the entire interaction earlier: the customer gets a heads-up while their card still works, updates it on their own schedule, and the renewal goes through without anyone noticing there was ever a risk. That shift is why pre-expiry alerts prevent roughly 85% of card-expiry failures outright, while even well-built reactive dunning sequences are working to recover a charge that has already failed. Toggle the "See it with Recurflux Card Health Monitoring" view in the estimator above to see exactly how much of your at-risk MRR moves into the protected column once the alerts go out before the charge — not after.
FAQs
FAQs
How do I stop losing subscribers to expired payment cards?
The fix is proactive outreach before the card expires, not reactive recovery after it fails. Approximately 2–3% of subscription cards expire in any 30-day window. Without pre-expiry alerts, 38% of those cards fail their next charge. With alerts at 30, 15, and 7 days before expiry, customers update before the charge fires — eliminating the failure entirely. Reactive dunning after a card_expired decline recovers a fraction of what proactive alerting prevents.
What happens to a subscription when a card expires?
When a card expires, the next subscription charge attempt will decline with a card_expired or expired_card error code. Without proactive alerts, the customer never knows their card has expired until they receive a "payment failed" notification — if you send one at all. At that point, the damage is done: the payment has already failed, the subscription may have lapsed, and the customer has to take reactive action. With card health monitoring, the customer is alerted 30, 15, or 7 days before their card expires and prompted to update proactively — before any charge fails.
How do I reduce payment failures from expired credit cards in my SaaS?
Card health monitoring is a proactive feature that scans your subscriber base for cards that are approaching their expiry date and sends pre-expiry alerts prompting customers to update their payment method before a charge fails. Recurflux runs card health monitoring at 30, 15, and 7 days before card expiry and sends branded emails from your domain. Customers who update proactively never experience a payment failure or access interruption — the charge succeeds on the first attempt.
How much MRR does card expiry cost each year?
The MRR impact depends on your subscriber count, ARPU, subscription age, and current recovery rate. A rough estimate: for every 500 subscribers at $79 average ARPU with a 14-month average subscription age, approximately 14 cards expire per month. Without proactive alerts, about 38% of those (5–6 cards) will result in payment failures, representing $400–500 in MRR at risk each month, or $5,000–6,000 per year. Card health monitoring prevents approximately 85% of those failures — around $4,200–5,000 in annually preserved MRR.
Can I rely on Stripe's automatic card updater instead of card health monitoring?
Stripe's Card Account Updater automatically updates card details when a bank issues a new card to replace an expired one — but this only works when the issuing bank participates in the Visa or Mastercard updater network. Coverage varies by bank and country. Typically 40–60% of expiring cards are updated automatically by Stripe. The remaining 40–60% require the customer to manually update. Card health monitoring covers the gap by proactively prompting those customers to update before the charge fires.
Does card expiry affect RevenueCat or app store subscriptions?
App store subscriptions (billed through Apple App Store or Google Play) are managed by the platform, not your payment processor, so traditional card expiry mechanics work differently. RevenueCat subscriptions on the App Store use Apple's billing system, which handles card updates internally. Card health monitoring in the traditional sense (pre-expiry alerts) applies primarily to card-based subscriptions through Stripe, Paddle, Razorpay, and Cashfree — not to App Store or Google Play subscriptions. Recurflux covers card health monitoring for Stripe, Paddle, Razorpay, and Cashfree.
What is the difference between card expiry and a card decline?
A card expiry happens on a known, predictable date — the card reaches its printed expiry month and can no longer be charged. This is preventable with proactive monitoring. A card decline (such as insufficient_funds or do_not_honor) happens unpredictably due to bank decisions, balance issues, or fraud flags. Card health monitoring specifically addresses expiry — the predictable failure type. For unpredictable declines, code-specific retry logic and dunning sequences are the recovery mechanism. Both types of failures are covered by Recurflux.
How do I know when a subscriber's card is about to expire?
Stripe returns the card expiry month and year on every payment method object via the API. You can query your Stripe payment methods to find cards expiring in the next 30, 60, or 90 days. Recurflux does this automatically — it scans your subscriber base on an ongoing basis and flags cards approaching expiry without any manual queries. For Razorpay and Cashfree, Recurflux reads payment method data from the processor API. For Paddle, expiry data is available through the billing system.
How much does card health monitoring cost?
Recurflux Card Health Monitoring is included in the Surge plan at $159/month. It runs automatically — no setup, no manual queries, no engineering work. At the typical SaaS subscriber scale where card expiry saves more than $159/month in prevented failures (usually around 5+ prevented failures per month at ~$79 ARPU), the feature pays for itself. For most SaaS businesses with 200+ subscribers, the monthly savings from card health monitoring typically exceeds the full Surge plan cost.
