Understanding Credit Cards: Key Concepts

What Is a Credit Card?

A credit card is a payment card issued by a financial institution that allows the cardholder to borrow funds up to a predetermined limit for purchases or cash advances. The borrowed amount must be repaid, typically on a monthly basis, either in full or through minimum payments, with interest charged on any outstanding balance. Credit cards differ from debit cards, which draw directly from a checking account, as they provide access to a revolving line of credit.

How Credit Cards Work

• Each card has a credit limit, which is the maximum amount that can be borrowed.
• Purchases made with a credit card are billed monthly. Cardholders receive a statement listing transactions, fees, and the minimum payment due.
• If the full balance is paid by the due date, no interest is charged on purchases. Carrying a balance results in interest charges, often at a higher rate than other forms of credit.
• Timely payments and responsible usage can help build a positive credit history, while missed payments or high balances can negatively impact credit scores.
