Key Takeaways

A cash back credit card is a type of rewards card that offers cash rewards on eligible purchase.
The best cash back credit cards for you may reward the types of purchases you already make frequently.
Remember to track your rewards' limits or expiration dates so you don’t miss out.

Many people use a credit card for daily shopping to earn rewards. A cash back credit card is a rewards card that offers cardmembers a percentage of eligible purchase back in the form of cash, which you may receive as a statement credit, gift card, or even a deposit.

Cash back rewards may amount to a few cents per purchase, but they add up quickly when you use your card strategically. The rewards you earn may help you pay bills, shop at your favorite stores, and get more out of your spending, all while you build your credit history.

Benefits of a cash back credit card

Some rewards credit cards are complicated, but a cash back credit card makes it easy to earn and use rewards. You usually earn a percentage back from eligible purchase when you use your cash back credit card. For example, if a card has a 1% cash back rate and you spend $1,000 on qualifying purchases, you’ll earn $10 back.

Depending on the card, you may redeem your rewards for a statement credit or gift card, or you might be able to put the cash back towards certain purchases online.

Which credit card gives the most cash back rewards?

Credit card issuers offer a wide range of rewards programs for people with different lifestyles, financial backgrounds, and priorities. Before you apply, check your credit score so you may better understand your options.

If you have an excellent credit score, you may have many cash back card options. But even if you’ve just started building credit history, there may be a cash back card for you.

For example, Discover offers two student credit card options designed to help college students learn responsible credit skills and earn rewards: the Discover it^® Student Chrome Card and the Discover it^® Student Cash Back Card. Because students may not have established credit scores, there’s no credit score required to apply for Discover Student credit cards.² Both cards allow you to earn cash back on everything you buy.

Once you have an idea of the credit cards you may qualify for, consider how you’d prefer to earn cash back. You may have one of three ways to earn rewards:

Flat-rate rewards cards

Flat-rate rewards cards offer a straightforward way to earn cash back—you’ll get the same percentage back on every purchase you make with your card, like 1% of every purchase. While the rewards rate on flat-rate cards is often lower than on other types of cards, you may be able to earn unlimited cash back. So, a flat-rate card may offer a high value, especially as your everyday card.

Tiered rewards cards

With tiered rewards, you may earn a higher cash back reward on purchases in certain spending categories, like gas, groceries, or restaurants, and a lower percentage on all other purchases. There may be limits to the amount you can earn in the higher-reward categories, though you may still be able to earn unlimited cash back at the lower rate.

Rotating category rewards cards

Like tiered rewards cards, rotating category cards offer a higher percentage of rewards in a specific bonus spending category, usually with a lower flat rate on other purchases.

Throughout the year, the rotating spending category changes. For example, you may earn 5% cash back on streaming services one quarter and department store purchases another.

With the Discover it^{^®} Cash Back credit card, you earn 5% cash back on everyday purchases at different places you shop each quarter like grocery stores, restaurants, gas stations, up to the quarterly maximum when you activate.

There’s typically a limit to how much you may earn in each rotating category. You may also have to opt in to the bonus category every time it changes. Otherwise, you might miss out on potential earnings.

How many cash back rewards can you earn with your credit card?

The amount of cash back rewards you can earn depends on the card you choose and how you use it. Some credit cards may cap your rewards at a certain amount or limit your earnings in bonus categories. Other cards might offer unlimited rewards at a lower rate.

How to maximize your cash back rewards credit card

By choosing and using the right card thoughtfully, you may maximize your cash back.

Choose the best credit card for your spending habits

Cash back credit cards come in many forms. The best cash back card for you should align with your spending habits and credit needs. Look for one that rewards your everyday purchases to maximize your earnings. If you’re not sure where to start, check your bank statement to see where you spend money most often.

If you spend a lot on gas and meals, a card that rewards those areas may be the best credit card for you. For example, with the Discover it^® Chrome Gas & Restaurant Credit Card, you can earn 2% Cashback Bonus^® at Gas Stations and Restaurants on up to $1,000 in combined purchases each quarter, automatically.³

Pay your balance in full each month

Pay your credit card balance in full and on time each month to establish healthy spending habits and a strong payment history. If you stick to the minimum payment, you may end up with a high balance and mounting interest charges. And too much interest may cost you more than you earn in rewards. But you might not owe any interest if you pay your balance in full each month.

Many credit card companies offer mobile banking app and online banking tools to help you manage your account. You may be able to make automatic payments from your bank account, track your statements, check your current balance, set spending limits, and more.

Maximize credit card welcome offers

Your credit card issuer may offer new cardmembers the opportunity to earn welcome bonus rewards within the first year of their account being active. You may be able to get extra cash back, credit card points, or miles if you reach a specific spending minimum by a set date (for example, $1,000 in the first three months after opening your account).

Generally, it’s not a good idea to charge more than you can afford to meet a spending minimum. But if you can comfortably meet the spending requirement—or your cash back card doesn’t have one—then you may not want to leave bonus rewards on the table.

Did you know?

With Discover, you don’t have to reach a spending minimum to earn a cash back. Only Discover automatically gives unlimited Cashback Match to all new cardmembers: we'll match all the cash back you've earned at the end of your first year.⁴

Pay attention to bonus categories

Use your credit card for purchases in categories with bonus rewards rates. For example, if your credit card rewards grocery purchases, use it to stock your fridge and pantry. You may even make a credit card payment equal to the purchase amount right away if you want to avoid carrying a balance.

It’s especially important to keep track of your bonus categories if you have a rotating rewards credit card. Typically, rewards categories change on a fixed schedule. Consider setting a reminder or marking your calendar for the date the rewards category switches. That way, you don’t forget to activate your new offer for bonus cash back.

Avoid common mistakes when using cash back rewards credit cards

When using cash back credit cards, it’s important to know which pitfalls can offset your cash back rewards earnings:

Using too much credit: Using your credit card to earn rewards is a great way to make the most of purchases you have to make anyway, but overspending to earn rewards may backfire. Coming too close to your credit limit may hurt your credit score by increasing your credit utilization, which is the portion of your available credit in use at once.
Missing expiration dates:
Yes, some rewards may expire. Keep an eye on those expiration dates and redeem your cash back, points, or miles before the cut-off date. With a Discover Card, your cash back doesn’t expire for the life of the account.⁵
Overlooking an annual fee:
Some rewards credit cards have an annual fee. Consider whether the value of your potential rewards earnings is higher than the annual fee to determine if it’s worthwhile.

The bottom line

A cash back credit card can be an excellent financial tool, as long as you use it wisely. High credit card debt may offset any rewards you earn. Responsible financial habits, like paying your credit card bill on time each month and keeping your balance to a minimum, can help you earn rewards while building a strong credit history.
