About Credit Card Issuer (Interest Charges)
The descriptor "INTEREST CHARGES - PUR CH" typically indicates interest assessed by your credit card issuer on purchase balances that were not paid in full by the due date. This is an internal bank or card-issuer fee line, not a charge from an external merchant, retailer, or service provider.
You usually see this type of entry when you carry a balance from one statement period to the next, or when a promotional rate expires and standard purchase APR applies. The amount will depend on your card’s interest rate, your average daily balance, and how your issuer calculates interest. It may post monthly or at other regular intervals, separate from individual purchase transactions.
If you have questions about this charge, review your card statement’s interest and fee summary section or the pricing details in your cardmember agreement. To resolve concerns, contact the customer service number on the back of your card or use secure messaging in your bank’s app or website—only your specific bank or card issuer can explain or adjust these interest charges. You can also verify by comparing the posted amount to the interest calculation shown on the statement (often labeled as “Interest Charged” or “Interest on Purchases”).
