If you’re new to credit cards, or even an old hand with cards looking to simplify with cash back, trying to figure out how to earn cash back can be overwhelming. Compared to other rewards systems, though, cash back is wonderfully straightforward. Ultimately, the best cash back credit card for you is one you’ll be able to swipe regularly, and that rewards you for the kind of spending you do the most. But where to start?

Here’s everything you need to know about choosing a cash back credit card and some top picks to get your search started.

What is a cash back credit card?

Cash back credit cards are a type of rewards credit card that refunds you a certain percentage of every eligible purchase you make. For example, spending $100 on a card that has a 1 percent cash back rate would earn you $1. Though that may not sound like much, rewards can quickly add up over time, especially if you take advantage of bonus cash back that can climb up to 5 percent or 6 percent on certain categories. Swipe your card consistently and pay your balance in full each month to prevent interest charges from eating into your returns, and you can end up with a sizable surplus.

Cash back cards offer several advantages over other rewards credit cards. For instance, points and miles can vary in value depending on how they are used, but cash back is generally worth the same amount when traded for a statement credit, direct deposit or check. That said, redemption options such as gift cards or merchandise tend to yield lower value. Cash back is also more flexible than points or miles, as you can choose to directly deposit your rewards into your bank account and then spend it on anything you wish.

What types of cash back cards are there?

Speaking of flexibility, cash back cards can have a variety of earnings schemes, allowing you to really maximize your rewards. You have three different types of cash back programs from which to choose: flat-rate, fixed bonus categories and rotating bonus categories.

There is no one-size-fits-all cash back card winner as the credit card that can deliver the most cash back for you will depend on your everyday spending habits. While flat-rate cards can be a good choice for those who prefer a hands-off approach to earning rewards, you may be able to boost your overall returns with a card that provides cash back in a handful of fixed or rotating bonus categories.

Here’s how each form of cash back works:

Flat-rate cash back cards

Flat-rate cash back cards earn you a fixed percentage (usually between 1 percent and 2.5 percent) on all eligible purchases, whether you’re booking long-awaited travel or spending a ton on groceries for a big family. This simple rewards structure makes it easy to get cash back on your everyday expenses and a card with a flat cash back rate on the higher end of that percentage range can be lucrative if you qualify.

When picking a flat-rate cash back card, you should opt for one with at least 1.5 percent cash back. This is because most cards with bonus categories offer 1 percent cash back on all other purchases anyway. Ideally, you should be looking at 2 percent cash back cards. The Wells Fargo Active Cash℠ Card offers a flat 2 percent cash rewards on purchases with no spending cap, and so does the Citi® Double Cash Card (earns 1 percent when you make the purchase and another 1 percent when you pay it off).

Fixed bonus category cards

A fixed bonus category card offers a higher cash back rate in specific categories and a base 1 percent cash back on all other purchases. The bonus category is often capped at a certain spend amount, after which time the base rate will apply to spending in that category. Common fixed bonus categories include dining, groceries and purchases at U.S. gas stations.

The Blue Cash Everyday® Card from American Express is an example of a cash back credit card with no annual fee that offers bigger rewards in certain purchase categories: 3 percent cash back at U.S. supermarkets (on up to $6,000 in purchases per year, then 1 percent), 2 percent cash back at U.S. gas stations and select U.S. department stores (including Macy’s and JCPenney) and a flat 1 percent on everything else.  If you’re willing to pay a $95 annual fee ($0 for the first year), the Blue Cash Everyday’s sibling card, the Blue Cash Preferred® Card from American Express offers 6 percent cash back at U.S. supermarkets (on up to $6,000 in purchases per year, then 1 percent) and 3 percent at U.S. gas stations.

Rotating bonus category cards

Rotating bonus category cards offer higher cash back percentages (typically 5 percent) in purchase categories that change every quarter. Common bonus categories include everything from home improvement stores and streaming services to drugstores and wholesale clubs. Many cards require you to opt-in or activate the bonus categories to get the higher cash back rate, so it’s a good idea to schedule calendar reminders so that you don’t miss out.

Card issuers also often impose spending caps on this type of cash back. The Chase Freedom Flex℠, for instance, earns 5 percent cash back on up to $1,500 in activated bonus-category purchases each quarter. After that, the cash back rate reverts to 1 percent.

What to consider when choosing a cash back credit card

While cash back is probably the least complicated rewards currency, your choices can vary widely in terms of rewards systems and other features. By figuring out what to look for, you can better understand how to choose a cash back credit card that meets your needs.

Here’s what to consider before adding a cash back credit card to your rotation:

Cash back rate/rewards structure

Take note of the card’s cash back rate and overall rewards structure. Pay attention to the small details like if the cash back rewards are flat-rate, if the rotating bonuses require quarterly activation (they usually do) and if there is a spending cap on how many rewards you can earn.

Spending habits

Think about your current spending habits, as well as any big purchases you have planned soon, to see if they line up with the card’s cash back categories.

One of the best ways to maximize your cash back earnings is to pair one or more tiered cash back cards that reward your most frequent purchases with a high-earning flat-rate card to cover everything else. Decide if you’re willing to keep track of which credit card to use at which store to get the maximum cash back rate on every purchase.

Annual fee

Many of the strongest cash back credit cards have no annual fee, but some issuers will charge you for the privilege of holding their card in your wallet. If the card you’re eyeing has one, crunch the numbers to see how much you’d have to shell out to recoup that out-of-pocket expense in rewards.

Consider the Blue Cash Preferred Card, which charges a $95 annual fee after the first year. If you max out the grocery category (6 percent back on up to $6,000 at U.S. supermarkets each year, then 1 percent), which works out to just $500 a month on groceries, you’ll get $360 in cash back. And that’s not even considering the 3 percent at U.S. gas stations and transit and 1 percent on everything else.

Interest rates

Regardless of whether or not you intend to carry a balance, it’s important to be aware of your credit card’s interest rate. The current average credit card interest rate is over 16 percent, which will add up quickly if you find yourself unable to make more than the minimum payment for any reason.

If you’re also looking to score an intro APR on purchases (or balance transfers) for a limited time, be sure to also consider the ongoing interest rate when your intro APR period ends.

Redemption options

Credit card rewards are only worth something when you actually cash them in. A Bankrate survey found that 31 percent of cardholders didn’t redeem any rewards in 2020. To avoid leaving money on the table, evaluate the card with an eye toward usability. Keep an eye out for issues like minimum redemption requirements and cash back expiration policies when evaluating a cash back credit card.

Additional benefits

Depending on your goals, other features to look for in a cash back credit card may include welcome offers, travel insurance or purchase protections such as extended warranty or trip cancellation/interruption coverage. Consider whether you’d actually take advantage of those perks and how much they might be worth to you.

Credit score requirements

Check your credit score for free to get a better gauge of your approval odds, and keep in mind that new inquiries have the potential to lower your scores by a few points. While the drop is temporary, there’s no use in incurring a hard credit pull if you’re unlikely to get a favorable response to your application.

  • Rewards rate: 5 percent cash back (tracked as points) at and Whole Foods Market; 2 percent back at restaurants, gas stations and drugstores; 1 percent on all other purchases
  • Annual fee: $0 ($119 Amazon Prime subscription required)

While the Amazon Prime Rewards Visa Signature Card doesn’t have a traditional annual fee, it does require an Amazon Prime membership ($119 per year). But with a strong 5 percent cash back rate at (and Whole Foods Market), as well as good rewards on gas station and drugstore spending, fans of online shopping should have little trouble earning it back. You’ll have a ton of ways to use your rewards, too, from statement credits and direct deposits to travel and gift cards, all with no minimum redemption requirements.

Chase Freedom Unlimited®: Best for an easy-to-earn sign-up bonus

  • Annual fee: $0

The low spending threshold on the Chase Freedom Unlimited’s welcome offer gives new cardholders the chance to earn a cool $200 pretty quickly after opening their account (after spending $500 on purchases within the first three months). But the potential to pair the Freedom Unlimited with another Chase card that earns Chase Ultimate Rewards is where things get really interesting. You’ll then be able to use your cash back to book travel in the Chase Ultimate Rewards portal, boosting its value by as much as 50 percent. There’s a range of additional perks for being a cardholder, including a free three-month DashPass subscription and Chase’s Pay Yourself Back tool.

The bottom line

Cash back credit cards are a great way to get a little something back on your everyday spending. When choosing a card, carefully consider your spending habits and how hands-on you want to be with your credit card strategy to ensure you can get the most out of cash back. Regardless of the cash back card you choose, remember to pay your bill in full every month. With current APRs hovering above 16 percent, interest charges can erase the cash back you earn faster than you might imagine.
