Debit Cards vs. Credit Cards

Debit and credit cards may look alike, but they work very differently — and understanding those differences helps people make smarter financial decisions.

What Is a Debit Card?

A debit card allows you to pay using the money you already have in your bank account.

• Direct from your account: Each purchase withdraws funds from your checking account immediately.
• No borrowing or interest: Since you’re spending your own money, you don’t owe interest.
• Helps you stay on budget: You can only spend what’s available (unless you opt into overdraft services, which may include fees).
• Credit score impact: Debit card use does not build or affect credit history.

What Is a Credit Card?

A credit card lets you borrow money from a card issuer and pay it back later.

• Borrow now, repay later: Purchases are charged to a line of credit up to a set limit.
• Interest may apply: If you don’t pay your balance in full each month, interest charges apply.
• Builds credit: Responsible use (on‑time payments, low balances) helps build credit history.
• Strong fraud protection: Credit cards often provide enhanced fraud dispute rights.
