Credit card vs. debit card: What’s the difference?

Have you ever wondered about the uses of a debit card vs. a credit card? It’s likely you have both types of cards in your wallet right now, giving you a choice every time you make a purchase. In many cases, you have only a few seconds to decide which payment option best fits the situation.

You may still wonder if you’re making the best choice when deciding which card to use. That same question often comes up every time you make a purchase: “Should I use a credit card or debit card?”

Being unsure about the difference between a credit card and a debit card or when to use each is a common challenge. The more you understand the benefits of both types of cards, the more confident you can become with your spending decisions. Beyond giving you an easier way to pay without carrying cash, each card has features that may fit different financial goals.

Below, our guide, “Credit card vs. debit card,” breaks down how each card works and helps you decide which option may be right for you.

Credit cards and debit cards both offer an easier way to pay for things. But they work quite differently behind the scenes. As a result, they each appeal to different types of people, says Lou Haverty, founder of a career advancement website for financial professionals.

A credit card is a type of revolving credit. That means you borrow money up to a set limit and pay it back over time. If you don’t pay off the full balance each month, you’ll be charged interest on what you owe. Interest is an extra charge on top of the money you’ve borrowed as a fee for using the funds. A debit card, on the other hand, is linked to a bank account, usually a checking account. The money is withdrawn from your account as soon as you make a transaction, sometimes using a PIN, a secret code of numbers you enter to confirm the purchase is authorized by you.

One difference between debit and credit cards is how the amount of money you can spend is determined. With a credit card, the amount you can spend depends on what’s called your credit limit and the amount of money you already have on the card. If you have a $1,000 credit limit and a $600 balance from previous purchases, you can continue to charge an additional $400. When you’ve reached your credit limit, you won’t be able to use the card for more purchases until you pay off at least part of the balance. You owe a minimum payment, which is the smallest amount your card provider requires you to repay to keep your account in good standing.

When comparing a debit card vs. a credit card, remember that most credit cards have an interest rate called an annual percentage rate (APR). This rate is the cost of borrowing money you don’t pay back from month to month.

“Credit cards require a responsible approach to your personal finances because you have the ability to spend beyond what you might have as cash in your bank account,” Haverty says.

Another difference between debit and credit cards is that with a debit card, money is pulled directly from the checking account balance the card is linked to. In a traditional account setup, you can’t spend more than what you have in the account, which helps lower the chance of racking up debt. If your account offers overdraft protection, you may be able to spend more than your account balance by using funds from a different linked bank account.

Another key difference between a debit and credit card is what it takes to get one. To open a debit card, you usually just need a bank account. Getting approved for a credit card is a different story. It usually depends on your credit score, which is a number that tells lenders how reliably you’ve paid back money you’ve borrowed in the past.

“The higher your credit score, the more likely you are to be approved,” Haverty says. “If you have a lower credit score, you may still get approved, but you might have a lower credit limit.”

Patricia Stallworth, a CFP® and senior financial planner at a financial planning firm, says that getting approved for a credit card depends on more than just your credit history. Factors such as if you have a job or not may also play a role in whether you’re approved for a credit card.

When comparing a debit card vs. credit card, consider that a debit card is typically given automatically when you open a checking account. This process usually requires some personal information, such as a Social Security number, driver’s license, employment information and email address. A deposit may also be needed to fund the account and complete the application. Once your card arrives in the mail, it’s easy to activate your new debit card right in the Capital One mobile app so you can start using it immediately.

When it comes to debit card vs. credit card, there are times in which using either card could fit the bill, depending on your financial needs and goals. Use the outline below as a guide for when the question of “When should I use my credit card vs. debit card?” comes up:

• You’re new to using a card to make purchases. Until you know you can limit your spending with a card, a debit card could be the way to go. You can learn to build good money habits with a debit card, since it helps you spend only what you can afford. “Debit cards are great for everyday purchases that you have budgeted for because the money comes directly out of your account,” Stallworth says.

• You want cash back without the fees. If your debit card is linked to a checking account that offers perks, you may be able to earn rewards without the fees. “While there’s generally no cost to participate in debit card rewards programs, the costs and fees may be higher with some credit card programs,” Stallworth says.

• You have debt you can’t pay off. If you’re wondering, “When should I use my credit card vs. debit card?” think about your debt. “If you’re struggling to manage or get out of debt, a debit card should be your go-to card,” Stallworth says. “You can’t get out of debt if you keep charging.”

• You want cash at the register. If you’re a fan of the envelope budgeting method, you may prefer using cash to help manage your spending. With this approach, you divide your money into separate envelopes for different spending categories, such as groceries or entertainment. Some stores let you get cash back at the register when you pay with your debit card, making it easy to refill your envelopes without visiting an ATM. “A credit card will most likely charge you a cash advance fee if that feature is available,” Haverty says.

• You want product coverage. Some credit cards come with purchase protection, which makes them a great option for online and large purchases, Stallworth says. “If I have a dispute with a merchant, I have more leverage with a large credit card company behind me.”

• You’re trying to build (or rebuild) your credit. “You will need a single credit card with a small limit that you pay off in full each month to build a credit history,” Haverty says. Or, if you’re unable to pay in full each month, be sure to make at least the minimum payment on time. A key difference between debit and credit cards is that using most debit cards won’t help you build a credit history. A debit card can help you build strong budgeting skills, so you’re better prepared to transition to a credit card.

• You want to earn rewards. If you’re debating between a debit card vs. a credit card, consider that credit card rewards programs may offer rewards in a specific category, like travel, Stallworth says. While it’s always important to read the fine print so you understand any fees or interest charges, you could find a credit card that offers valuable rewards. Some cards may help you earn free flights or cash back simply by using the card regularly.

Choosing between a credit card and a debit card depends on your financial goals and the type of purchase you’re making. Knowing how each card works can help you manage your money better while taking advantage of its unique benefits. When used responsibly, both can play an important role in your everyday finances.

What you need to know about credit card vs. debit card:

• Debit cards are a good choice for everyday spending when you want purchases to come directly from your bank account. 

• Credit cards can offer rewards, purchase protections and the opportunity to build credit when balances are paid in full. 

• Using both cards strategically can help you stay on budget while making the most of each payment method.
