How do cash back credit cards work?

Cash back credit cards reward cardholders for using their cards. Typically, rewards are based on a percentage of each purchase. How much that percentage is—and how cardholders are able to redeem rewards can vary based on the credit card issuer and the specific card. 

Generally, there are some types of transactions, such as balance transfers and cash advances, that don’t earn rewards.

Types of cash back cards

There are three general categories of cash back cards: flat rate, tiered and rotating category. How you get cash back rewards—and how much you earn—can depend on which type you’re using. Here’s a quick overview:

  • Flat-rate: With flat-rate cash back cards, the percentage you earn on purchases is generally the same on every transaction—whether you’re buying gas, groceries or something else. 
  • Tiered: Sometimes called bonus-category cards, rewards for tiered-category cards change based on the type of purchase. Higher-tier rewards percentages are usually on select bonus categories. Purchases outside those bonus categories generally earn rewards at a flat rate. 
  • Rotating category: Rotating cash back cards function much like tiered cards, but bonus categories can change periodically. These rotating categories will typically earn a higher rate than other purchases, while purchases that don’t fall into these bonus categories are typically rewarded with a flat cash back rate.

For cards that earn cash back on different categories, card issuers rely on a four-digit number called a merchant category code. These codes are assigned to each credit card transaction and help issuers identify which purchases qualify for earning rewards.

Capital One cash back credit cards

The Quicksilver and QuicksilverOne cards are two examples of flat-rate cash back cards. They both offer unlimited 1.5% cash back on every purchase, every day. But there are elevated rewards for cardholders on Capital One Travel.

SavorOne has tiered rewards, offering 3% cash back on dining, entertainment, popular streaming services and at grocery stores, plus 1% on all other purchases.1 SavorOne also has elevated rewards on Capital One Travel.

Ways to redeem cash back rewards

There are plenty of ways you might be able to redeem cash back rewards, including: 

  • Online shopping: Some cards may let you put your rewards toward future purchases. For example, Capital One lets you use your rewards to shop online with PayPal and at Amazon.com.2
  • Gift cards: Some issuers let you redeem your cash back rewards in the form of gift cards to popular retailers, restaurants and more.
  • Statement credits: You might be able to apply your cash back rewards directly to your credit card’s balance as a statement credit.
  • Checks or direct deposits: Some cards let you redeem your cash back rewards in the form of a check or a direct deposit to your checking or savings account. 
  • Other options: Some card issuers may give you other cash back redemption options, like donating your rewards to charity or using your rewards to cover all or part of a past purchase. 

Keep in mind that how you can redeem your cash back rewards can vary from card to card and issuer to issuer. Check your card’s terms and conditions closely to better understand when and how you can redeem your rewards.

Benefits of cash back credit cards

Earning cash back rewards can be a great advantage to having a credit card. But there are more advantages to using a cash back card than just rewards. 

Some cash back cards may offer introductory perks, including:

  • Early spend bonus: Sometimes referred to as a sign-up or welcome bonus, you’re generally required to spend a certain amount within the first few months of opening the card. Once you reach the specified amount, you can get the bonus on top of your regular cash back earnings.
  • Low or 0% introductory APR: A low or 0% promotional interest rate could be helpful if you want to make a larger purchase. You’ll typically have more time to pay off your purchase while paying minimal or no interest.

Other cash back credit card benefits might include unauthorized charge protection and digital tools to help you keep an eye on your finances. With responsible use, you can build your credit. Learn more about the advantages of using credit cards.

What to know before applying for a cash back credit card

Beyond the rewards themselves, there are a few things to consider before you apply for a cash back card—or any credit card, really:

Check the terms, conditions and fees

How you earn and redeem cash back rewards is important. But it’s also a good idea to take a look at things like interest rates and annual fees to decide whether a particular cash back card is right for you. Looking at rates, rewards and fees can give you a good starting point to compare cards and find the one that fits your needs.

Understand rewards redemption options

Make sure you understand how long rewards can be used. For example, Capital One rewards don’t expire for the life of the account and there’s no limit to how much you can earn. It also might help to remember that the value of the cash back you’ve earned could be outweighed if you revolve a balance and accrue interest. Paying off your balance every month is one way to avoid interest and get the most out of your rewards.

Review application requirements

Credit card issuers consider many factors, including credit scores, when deciding whether to approve an applicant for a credit card. Monitoring your credit can help you see where you stand. And checking for pre-approval can let you see whether you’re eligible for certain cards before you apply.

Be aware of how a cash back card could impact credit

If you decide to apply for a credit card, including a cash back card, be sure you understand how that could affect your credit. If your credit application involves a hard inquiry, your credit score could take a temporary hit. And applying for multiple credit cards during a short period could send negative signals about your finances, according to the Consumer Financial Protection Bureau.

Practice responsible habits

Personal responsibility and credit go hand in hand. So before you start making plans for your rewards, be sure you know things like when your bill will be due each month and where you can find your minimum payment.
