What is the minimum charge to keep a credit card active?
A minimum charge is the smallest posted transaction that can create account activity on a credit card.
There is usually no official minimum
Issuers generally do not publish a minimum purchase amount for preventing inactivity closure. In practice, the posted transaction matters more than the size of the transaction.
Cardholders often use small subscriptions, donations, or occasional tiny purchases to create activity.
Why posting matters
Pending charges can disappear or fail to settle. A posted charge is the clearer account-activity signal.
If you are using a very small charge, wait until it appears on the account rather than assuming authorization alone was enough.
Do not forget payment
The smaller the charge, the easier it is to overlook. Pair any activity charge with statement-balance autopay and receipt notifications.
Avoid carrying interest on a charge that was only meant to preserve the account.
