Debit card vs. credit card, the differences that matter

Both look almost the same and swipe at the same terminal, but they work very differently. Understanding the differences helps you avoid fraud losses and fees, and build credit history.

The core difference

• Debit: money comes straight out of your bank account. You spend what you have.
• Credit: the issuer lends you money and you pay it back later. If you do not pay the full balance, interest is charged.

Quick comparison

	Debit	Credit
Source of money	Your checking account	A line of credit
Interest	No	Yes, if you do not pay in full on time
Builds credit history	No	Yes, if the issuer reports to the bureaus
Overdraft risk	Yes, if you opted in to coverage	No (over-limit only if you agreed to it)
Fraud protection	Depends on how fast you report	Broader under federal law
Temporary holds (hotels, gas)	Lock up money in your account	Use part of your credit limit

Fraud protection: the biggest difference

With a credit card, the Fair Credit Billing Act caps your liability for unauthorized charges at $50, and often it is $0. While you dispute a charge, the money does not leave your pocket.

With a debit card, the Electronic Fund Transfer Act also protects you, but the limit depends on when you report, according to the FTC:

When you report	Your maximum liability
Before any unauthorized charges	$0
Within 2 business days of learning of the loss	$50
After 2 business days but within 60 days of the statement	Up to $500
More than 60 days after the statement	You could lose everything taken after that point

Also, with debit the money has already left your account while the bank investigates, which can affect rent or bill payments. Many issuers offer more generous voluntary policies, but it is worth knowing the legal minimum.

Advantages of each

Debit

• Easy to control: you cannot spend more than you have (if you declined overdraft coverage).
• No risk of building interest-bearing debt.

Credit

• Builds credit history when you pay on time.
• Stronger fraud protection for online purchases and travel.
• Some offer rewards, though they are only worth it if you pay the full balance.

When to use each

• Online shopping, travel and gas stations: many people prefer credit for fraud protection and to avoid holds on their bank account.
• Daily spending on a tight budget: debit helps you avoid overspending.
• Building credit: use a credit card for small expenses already in your budget and pay it in full every month.

A middle option: secured credit cards

A secured credit card requires a deposit that usually equals the credit limit. It works like a credit card and, if the issuer reports your payments, it helps build credit history. It is a common first step.

Before you choose

Check the APR (explained in what is APR), annual fee and other fees. If you use debit, check whether you opted in to your bank’s overdraft coverage; see how to avoid overdraft fees.
