Where to find your payment method settings in Kindle Unlimited
Your Kindle Unlimited payment method lives in your Amazon account settings, not in a separate Kindle app or dashboard. You change it the same way you would change the card on file for any Amazon purchase — through the "Your Account" section of Amazon.com.
Log into Amazon.com with the account linked to your Kindle Unlimited subscription. Go to "Account & Lists" in the top right corner, then select "Your Account." From there, click "Payment options" in the left sidebar. This page shows every card, bank account, and digital wallet Amazon has on file for you, and which one is currently set as your default.
Kindle Unlimited charges to whichever payment method is set as your default at the time your monthly billing date arrives. If you want to use a different card or account, you either add a new payment method and make it default, or you delete the old one entirely. Amazon will not let you have a payment method on file that is not set to something.
Key Takeaways
- Your Kindle Unlimited payment method is managed through Amazon.com's "Payment options" page, not through the Kindle app or any Kindle-specific interface.
- Kindle Unlimited charges to your default payment method on your billing date, so changing which card is default changes where the charge goes.
- You can add a new payment method and make it default without deleting the old one, or delete the old method entirely if you no longer need it.
- Changes to your payment method take effect when ready, but the next charge will use the new method only if the change happens before your billing date.
Adding a new payment method and making it your default
On the "Payment options" page, click "Add a payment method" at the bottom. Amazon will ask whether you want to add a credit card, debit card, or bank account. Enter the card number, expiration date, and CVV, or the routing and account number for a bank account. You will also need to enter or confirm the billing address associated with that payment method.
Once you have added the new method, it does not automatically become your default. Look for the payment method you just added in the list. Click the three-dot menu next to it and select "Set as default payment method." Amazon will move it to the top of the list and mark it with a blue checkmark. This is the method Kindle Unlimited will charge on your next billing date.
If you want to keep the old payment method on file in case you need it later, you can leave it there. If you want to remove it, click the three-dot menu next to the old method and select "Delete." Amazon will ask you to confirm. Once deleted, that card or account is no longer stored in your account.
What happens if your payment method fails
If Amazon tries to charge your default payment method on your billing date and the charge fails — because the card is expired, the account is closed, or the card issuer declines the charge — Amazon will not when ready cancel your Kindle Unlimited subscription. Instead, Amazon will attempt to charge the payment method again over the next few days.
If all retry attempts fail, Amazon will send you an email asking you to update your payment method. You have a grace period, usually several days, to add a working payment method before Amazon suspends your Kindle Unlimited access. During this time, you can still read books you have already downloaded to your devices, but you cannot borrow new titles or access your library.
The fastest way to restore access is to go back to "Payment options," add a new working payment method, and set it as default. Amazon will attempt to charge it within a few hours. Once the charge goes through, your Kindle Unlimited access returns when ready.
Timing: when the change takes effect
Changes to your default payment method take effect when ready after you save them. However, the timing of when Kindle Unlimited actually uses the new method depends on when your billing date falls.
If you change your payment method more than a day before your billing date, the next charge will use the new method. If you change it on your billing date or after, Amazon may have already attempted to charge the old method. Check your email for a receipt showing which method was charged. If the old method was charged and you want the new method to be used going forward, you can change your default again, and the following month's charge will use it.
Your Kindle Unlimited billing date is the same day each month — usually the day you first subscribed or the day you reactivated after a pause. You can find your exact billing date by going to "Manage Your Kindle Unlimited" on Amazon.com and looking at the subscription details.
Using a digital wallet instead of a card
Amazon accepts payment through Apple Pay, Google Pay, and Amazon Pay (Amazon's own digital wallet system). If you have set up any of these on your Amazon account, they appear in your "Payment options" list just like a card would.
To use a digital wallet for Kindle Unlimited, add it to your Amazon account if you have not already, then set it as your default payment method the same way you would a card. When your billing date arrives, Amazon will charge the wallet, which in turn charges the card or bank account linked to that wallet.
The advantage of using a digital wallet is that you can change which card backs the wallet without logging into Amazon. For example, if you use Apple Pay and update your card in the Apple Wallet app, Amazon will automatically charge the new card on your next billing date without you needing to change anything in your Amazon account.
Changing payment method if you share an Amazon Household
If you are part of an Amazon Household — where multiple adults share one Amazon account or linked accounts — only the account owner can change the payment method for the shared account. If you are an adult member but not the owner, you cannot change the default payment method through "Payment options."
If you want Kindle Unlimited charges to go to a different card, you have two options. The first is to ask the account owner to change the default payment method for you. The second is to set up your own separate Amazon account and subscribe to Kindle Unlimited on that account instead, which gives you your own payment method and your own library.
If you have a child account in the Household, Kindle Unlimited is not available on that account. Only adult accounts can hold a Kindle Unlimited subscription.
Troubleshooting: payment method not updating
If you have changed your default payment method but Kindle Unlimited still charged the old card, the most common reason is timing. Amazon may have already processed the charge before you made the change. Check your email for a receipt showing which card was charged and when. If the charge went through on the old card, the next month's charge will use the new method.
If you changed your payment method more than a day before your billing date and the old card was still charged, log back into "Payment options" and confirm that the new method is marked as default. Sometimes the change does not save if your browser connection drops or if you navigate away from the page too quickly. Click the three-dot menu next to the new method and select "Set as default payment method" again.
If the new payment method itself is being declined, check that the card has not expired, that the billing address matches what your card issuer has on file, and that the card has not been flagged for fraud. Contact your card issuer directly if you are unsure. Once the card issuer confirms the card is active, try setting it as default again.
Frequently Asked Questions
Can I use different payment methods for different Kindle devices?
No. Kindle Unlimited is tied to your Amazon account, not to individual devices. All your Kindle devices pull from the same library and charge to the same default payment method. If you want different payment methods, you would need separate Amazon accounts.
What if I want to pause my Kindle Unlimited subscription instead of changing the payment method?
You can pause your subscription for up to three months without being charged. Go to "Manage Your Kindle Unlimited" on Amazon.com, click "Settings," and select "Pause subscription." This stops charges without canceling your account, so you can resume later without losing your library or reading history.
Does changing my payment method affect my Kindle Unlimited reading history or borrowed books?
No. Your reading history, bookmarks, notes, and borrowed titles stay exactly the same. Changing the payment method only changes where the monthly charge goes; it does not affect your library or any content you have already borrowed.
Can I set up automatic payments from a bank account instead of a credit card?
Yes. On the "Payment options" page, click "Add a payment method" and select "Bank account." Enter your routing number and account number. Once added, you can set it as your default the same way you would a card. Amazon will charge your bank account on your Kindle Unlimited billing date.
What happens to my subscription if I delete my only payment method?
Amazon will not let you delete your only payment method. You must have at least one payment method on file at all times. If you want to remove a card, you have to add a new one first and set it as default, then delete the old one.
