Your monthly credit card minimum payments may increase for a number of reasons. If you’ve been spending more, your balance will be higher and the monthly percentage of the balance owed will then increase. As you keep a balance on your credit card, you are adding on interest charges every month. Over time, this can add up to a substantial amount, which will increase your overall balance and your minimum monthly payment. Your minimum credit card payment may also increase if you’ve incurred late charges, so be sure to pay close attention to your statement due date each month.
