A credit card advance is significantly different from a checking account withdrawal. With a credit card advance, you are quickly getting access to cash from your credit card issuer. It is a form of a loan, and your interest rate will likely be between 17% and 29% until it’s fully repaid. With a checking account withdrawal, you are accessing your own money, so there’s no interest fee involved, though you might be charged a few dollars if you use an out-of-network ATM for the transaction.
