What is my Annual Percentage Rate (APR)?

If you are an existing customer, your APR (Annual Percentage Rate) was included in the Pricing Schedule, which is part of your Cardmember Agreement. Your APR can also be found on your monthly billing statement.

When is interest charged?

You will not be charged interest on purchases in a billing period in which you pay the new balance in full by the payment due date. If you do not pay your new balance in full by the due date in a billing period, we charge interest on all new and existing purchases for that billing period. For balance transfers and cash advances, we charge interest from the transaction date until you pay the total amount you owe.

How much do I have to pay each month?

Each billing period you must pay at least the minimum payment due by the payment due date shown on your billing statement. If you don’t pay at least the minimum payment due by the payment due date or have a returned payment, a late fee or returned payment fee may be charged to your account. You can pay more at any time. See your Cardmember Agreement for more details.
