Credit Card Payment Calculator
A credit card is a small plastic (or metal) card issued by banks, retailers, or credit unions that allows the holder to borrow funds for purchases or cash withdrawals. It’s a form of unsecured loan, meaning there’s no collateral. However, credit cards come with a credit limit, and exceeding it may incur fees.
