Credit cards: How is a cash advance different from a purchase? Why are the fees so high?
Essentially speaking, when you purchase goods worth $100 using your card, the store has to pay about $2 for the transaction to the company that operates that stores' credit card terminal.  If you withdraw cash from an ATM, you might be charged a fee for such a transaction. However, the ATM operator doesn't pay the credit processor such a transaction fee - thus, it is classified as a cash transaction.  Additionally, performing cash advances off a CC is a rather good indicator of a bad financial health of the user, which increase the risk of default, and in some institutions is a factor contributing to their internal creditworthiness assessment.
