A fee charged by a credit card company when you use your credit card to get cash advances. In many cases this fee is 3% of the cash advance amount with $5 minimum and no maximum. (The minimum is not charged on top of the 3%, instead it will be your total cash advance fee if 3% of the cash advance amount is less than $5.) If you will use your credit card to send money through companies such as Western Union all your charges will be considered as a cash advance and a cash advance fee will apply. There are no credit cards that do not charge a cash advance fee.
