Credit card

A card that lets you borrow up to a set limit for purchases and repay over time, with interest charged on balances not paid in full.

What it means

A credit card gives you a revolving line of credit. Each month you receive a statement and can pay the full balance, the minimum payment or anything in between. If you pay the full statement balance by the due date, most cards charge no interest on purchases thanks to a grace period. Any balance carried over accrues interest at the card’s APR, which is usually much higher than rates on loans secured by collateral.

Credit cards also offer stronger fraud protection than debit cards: federal law caps your liability for unauthorized charges at $50, and many issuers waive even that. Used carefully, cards can build credit and earn rewards; carried balances, late payments and high utilization can be costly and hurt credit scores.

Example

Suppose someone carries a $2,000 balance on a card with a 24% APR. That works out to roughly $40 of interest in a 30-day month, money that could be avoided by paying the statement balance in full.
