A cash advance is a service provided by most credit card and charge card issuers. The service allows cardholders to withdraw cash, either through an ATM or over the counter at a bank or other financial agency, up to certain limit on your credit card. A cash advance fee between 3-5% is normally assessed for conducting a cash advance and interest begins accumulating daily on your cash advance. Most financial institutions charge a higher APR for cash advances upwards of 20%. However, Members 1st Credit Union reduces your cash advance APR to the same as your purchase rate APR, as low as 9.99%.
