When we withdraw money from an ATM using a credit card, we call it a cash advance. The way cash advance works is no different from ATM/debit cards in general, however withdrawals on cash advance have a monthly credit card limit of 30%, so if you have a credit card with a limit of $1000 per month then the maximum cash withdrawal is only $300 per month. and this withdrawal is considered your loan to the bank which must be paid at the end of the month. Then you will be charged interest fees, transaction fees, service fees, late fees.
