The terms are default, grace period, late payment fee, over the limit fee, and bad credit

1. Bad credit

2. Over the limit fee

3. Late payment fee

Explanation:

1. Bad credit is a situation where a borrower fails to repay his bills on time. This can have an effect on his credit score, thus resulting in a bad credit score and the inability of lenders to lend money. This explains John's situation because he fails to pay on time.

2. Over the limit fee is charged when a person's balance exceeds his credit limit and this can result in a decline of transaction. Susan has apparently exceeded her limit and her transaction might be declined or the balance might be deducted when she pays the fee.

3. Late payment fee is charged when a person fails to complete his payment on the due date. Interest is being charged after the purchase which he pays at a later time because he failed to read the conditions of the credit card offer.
