For a late payment you could anticipate possible consequences such as: Interest Charges: You will of course be charged interest on the balance on your credit card that wasn’t paid off before the due date. Late Fees: Even if you make your payment a day or two after it was due, you’ll probably be charged a late fee, and an NSF fee if your payment bounced. You may also be charged an NSF fee from your bank, making a missed payment potentially quite expensive. Late fees and/or penalties will get added to your principal balance, meaning they’ll accumulate interest if your balance isn’t paid off in full. Credit Bureau Note: With a one-time late payment that you catch up within a few days you may not have any impact to your credit history report. If you make your payment a month or more later though, your credit card company will likely report these late or missed payments, which can result in your credit score taking a hit. Late payments can remain on your credit report up to 6 years from the date reported.
