Involuntary churn happens when a subscriber's payment fails, for example because a card expired, rather than because they chose to cancel. Both the App Store and Google Play retry failed payments for a period, and you can enable a grace period so users keep access while billing is retried. Add in-app messages asking users to update their payment method, and track recovered subscriptions as a separate metric.
Voluntary versus involuntary churn
Voluntary churn is a user deciding to cancel. Involuntary churn is a subscription lapsing because payment failed: an expired card, insufficient funds or a bank decline. The user often still wants the app.
Because these users did not choose to leave, involuntary churn is usually the easiest subscription revenue to win back.
How billing retry works
When a renewal payment fails, the stores keep trying to charge the user for a period of time. If a retry succeeds, the subscription continues. Store notifications tell your server when a subscription enters billing retry and when it recovers or expires.
Listen to these server notifications so your app knows the subscription state accurately rather than guessing from the device.
Grace periods
A grace period lets users keep access for a short time after a failed payment while the store retries. It prevents a paying user from losing access because of a temporary card problem, and it gives them time to fix payment details.
Enable grace periods in App Store Connect and Play Console if they suit your app; for most subscription apps they reduce lost subscribers and frustrated reviews.
Ask users to fix payment
Show a clear in-app message when a subscription is in a grace period or billing retry, explaining what happened and linking to the store's payment settings. Keep the tone helpful, not alarming.
Apple and Google also notify users about billing problems, but an in-app message at the right moment adds a strong nudge.
Use email and push carefully
If users opted in, email and push can remind them to update payment details. Send a small number of messages across the retry window rather than many in a few days.
See our push notification strategy and email marketing for apps guides.
Win back users after expiry
When retries end and the subscription expires, the user becomes a win-back candidate. Win-back offers and offer codes can bring them back with a discount or free period.
See subscription offer codes and win-back offers.
Measuring involuntary churn
Track the number of subscriptions entering billing retry, the share recovered during grace or retry, and the share that expires. Separate these from voluntary cancellations in reports.
Recovered revenue is a direct way to raise lifetime value, explained in mobile app LTV calculation.
Prevent payment failures
Encourage annual plans for loyal users, which reduces renewal events, and remind users before an annual renewal so the charge is expected.
Clear renewal information on your paywall reduces disputes and refunds. See paywall design best practices.
Effects on reviews and ratings
Users who lose access unexpectedly often leave angry reviews. Grace periods and clear messaging prevent many of these.

Common mistakes
Common mistakes include cutting off access immediately on failure, not listening to store server notifications, showing scary error messages, and counting involuntary churn as normal cancellation.
Another is spamming users with reminders, which drives them to cancel deliberately.
A worked example: a fitness subscription
A fitness app enables grace periods and adds a banner during billing retry linking to payment settings. It sends one email at the start of retry and one near the end.
A meaningful share of failed renewals now recover before expiry, and reviews about lost access drop.
Key takeaways
Involuntary churn is lost revenue from users who did not choose to leave. Enable grace periods, listen to server notifications, message users calmly in the app, and win back those who expire.
Measured separately, it often becomes one of the quickest revenue wins for a subscription app.
Checklist for subscription billing health
Confirm that server notifications are received and processed, grace periods are enabled, the app reads subscription status from your server, in-app messages appear during billing problems, and reports separate voluntary from involuntary churn.
Review the checklist after every major billing or account change, since small bugs here quietly lose revenue every month.
Billing problems by region and payment method
Payment failures are more common in some markets and with some payment methods, such as prepaid cards or carrier billing. Segment billing retry rates by country and payment method to see where users struggle.
Where failures are high, consider annual plans with reminders, local pricing and clear in-app guidance on updating payment methods in that market.
What to show during grace
During a grace period, keep the full experience available and show a calm banner rather than a blocking screen. Users who keep using the app are more motivated to fix payment.
After the grace period, show a clear screen explaining that the subscription paused because payment failed, with one button to fix it and a link to restore purchases.

- Add light remindersOne or two emails or pushes across the window.
- Measure recoveryReport involuntary churn separately.

Action plan
- Track subscription states server-side
- Enable grace periods
- Message users in-app
- Remind lightly
- Win back expired users
- Report recovery separately
Metrics to monitor
- Subscriptions entering billing retry
- Recovery rate during grace
- Involuntary churn rate
- Win-back conversion
- Billing-related review share
Record the baseline, release date, audience, markets, and external changes before interpreting movement. Rankings and conversion are useful signals, but a decision is stronger when activation, retention, and business value confirm that the page attracted the right users.
