Credit card fees are charges that cardholders may incur when using their credit cards. These fees can include annual fees, late payment fees, and foreign transaction fees. Annual fees are charged yearly for the privilege of having the card, while late payment fees apply if a payment is not made on time. Foreign transaction fees occur when purchases are made in a currency other than the card's base currency. Additionally, some credit cards may have cash advance fees, which are charged when cash is withdrawn using the card. Understanding these fees is important for managing credit card use and avoiding unexpected costs. Always read the terms and conditions associated with your credit card to stay informed.
