American Express Credit Cards are a convenient way to pay for everyday purchases. A credit card is a lending product. When you make a transaction using your Card, we are lending you that amount of money and you are essentially taking out a loan. As an American Express Cardmember, you have the flexibility to pay back the loan so that we receive your payment in full by the payment due date or over a longer period of time. A minimum payment is always due by the payment due date every month.
When interest is charged
If you always pay your balance in full so that we receive your payment by the payment due date, interest will not be applied to any of your purchases. If you choose to carry a balance or if we receive your payment late, interest charges are calculated and charged to your account. Interest is always charged on balance transfers and funds advances starting from the day the transaction occurs.
