Key points:

  1. With a cash back rewards credit card, you earn cash back from the credit card company for any eligible purchase.

  2. Cash back rewards typically give cash back for a certain percent of the purchase amount, based on the spending category.

  3. You can redeem your cash back rewards in different ways, such as a statement credit.

Many credit cards come with rewards programs like cash back that encourage you to use your card on everyday purchases. But what is cash back? Cash back is a type of reward from a participating credit card, debit card, or app that allows you to earn a percentage back in the form of cash on eligible purchases. Some cash back credit cards offer a standard percentage of cash back on all purchases. Others may provide a higher percentage of cash back for certain purchase categories like gas, food and drinks from restaurants, and travel.

How cash back works

Cash back programs may work a little differently across credit card issuers, retailers, and other financial service providers. However, some aspects typically stay the same across providers. Understanding the following functions of cash back can help you make informed decisions and compare your options.

Basic mechanics of cash back

Typically, cash back programs offer a certain earn rate. That means you receive a specific percentage of each eligible transaction amount as cash back. Sometimes, the earn rate is fixed across all purchases. In other cases, you may earn more at specific retailers or for specific purchases.

The cash back you earn builds over time. With some cash back providers, you have to reach a certain amount before you can redeem your rewards. With Discover® cash back credit cards, you can redeem any amount, any time.1

Each cash back rewards program may offer unique options and restrictions for redeeming your cash back.

What companies offer cash back rewards?

Cash back is a common credit card reward type. However, credit card issuers aren’t the only institutions that offer cash back programs–debit cards and retailers may also offer cash back. You can also enroll in cash back programs through certain mobile apps and websites.

  • Credit card cash back: Cash back often refers to credit card rewards programs that allow cardmembers to earn a percentage of qualifying purchases back as cash, which could be redeemed in various ways. 
  • Debit card cash back: Some debit card accounts also offer cash back rewards. Typically, cash back debit cards work similarly to credit cards: cardmembers earn a certain percentage back on eligible purchases.
  • Retailer cash back programs: Some retailers, like grocery or department stores, offer cash back rewards programs that allow shoppers to earn as they shop in-store or online. Like credit card rewards programs, they may offer a flat rate across all purchases with bonus rewards for certain items or during sales. In most cases, you can only redeem these cash back rewards at the retailer that issues them.
  • Cash back apps and websites: Some mobile apps and websites, like Ibotta or Rakuten, partner with retailers to offer cash back on certain purchases. To begin earning rewards, you may have to download an app or an internet browser extension. From there, when you shop with partnered establishments, you can begin earning cash back. You may be able to redeem that cash back in-store or through your bank account.

Types of cash back programs

Credit card rewards programs are the most prevalent way to earn cash back. Most cash back rewards fall into one of these categories.

  • Flat-rate rewards: With flat-rate cash back rewards cards, you earn the same percentage back on each eligible transaction, regardless of the item, retailer, or type of purchase.
  • Tiered rewards: Tiered cash back programs typically offer a flat rate on most purchases, plus higher, or bonus percentages in specific categories. For example, you might earn 1% back on most purchases, 2% on gas, and 3% on restaurants. Bonus earnings may have a cap for the amount you can earn in a specific time frame.
  • Rotating category rewards: Like tiered cash back programs, rotating category credit cards work by offering a higher rate on certain types of purchases and a flat rate everywhere else. However, those bonus categories change on a regular basis, like each quarter or each year. Understanding these categories could help you maximize your rewards.

Discover cash back

Discover® Cardmembers can earn rewards on every purchase with a Discover cash back credit card. Depending on the credit card, some cards will allow you to earn more on certain category purchases.

 

For example, some Discover cards let you earn 2% Cashback Bonus® at gas stations and restaurants on up to $1,000 in combined purchases each quarter, automatically. Plus earn unlimited 1% cash back on all other purchases.2

 

With other cards, including the Discover it® Cash Back Credit Card or Student Cash Back Card, you can earn more by activating the 5% Cashback Bonus program. Earn 5% cash back on everyday purchases at different places you shop each quarter like grocery stores, restaurants, gas stations, and more, up to the quarterly maximum when you activate. Plus, you earn unlimited 1% cash back on all other purchases – automatically.

How does Discover Cashback Match® work?

During your first year with Discover, you could earn even more cash back with Cashback Match. Discover Cashback Match® means that we’ll automatically match all the cash back you’ve earned at the end of your first year. There is no limit to how much we’ll match.3

More benefits from Discover

Discover rewards cards offer many standout features. Like all Discover credit cards, cash back cards have no annual fee. That way you don’t have to worry about the cost of using your card offsetting your cash back earnings. Plus, unlike some other credit card issuers, your rewards never expire1 with Discover.

Redeeming cash back

Once you’ve accumulated some cash back, you may want to redeem your rewards. Credit card issuers often offer a few options for redeeming cash back. The best choice for you depends on your priorities and financial situation.

  • Bank deposit: Cash back may be deposited directly into any bank account. With Discover, you can redeem your rewards for cash in any amount1 whenever you’d like. Other credit card issuers may require a minimum cash back rewards balance before you can cash out your rewards.
  • Statement credit: You may be able to apply your cash back to your credit card balance in the form of a statement credit. If your balance is higher than your cash back earnings, the statement credit could reduce what you owe. If your statement credit exceeds your balance, you may end up with a negative balance. In that case, you could continue to use your card normally until your balance is back in the positive or request a refund.
  • Gift card: Some credit card companies allow you to redeem your cash back in the form of a gift card for certain participating retailers.

Maximizing cash back rewards

You could earn cash back just by using your rewards card normally. However, if you want to take your rewards even further, a few considerations could help.

  • Consider welcome offers. Some credit card issuers provide introductory offers that could increase your cash back (like Discover Cashback Match). Others may have introductory periods with low interest rates. During that time frame, you could accrue a balance without interest eating a significant percentage of your rewards. However, it’s crucial to repay your balance before the introductory period ends. Otherwise, you may get stuck with interest.
  • Avoid overspending. Cash back shouldn’t be an incentive to spend too much. Instead, it would be best if you looked at cash back as a bonus reward or bonus cash for the money you’d spend anyway. The last thing you should do is charge more than you can afford to get more cash back. If you overspend and fall into debt, you risk running up interest charges that could cancel out the value of your rewards and negatively impact your credit score. You may also want to double-check the policy on your cash rewards credit card to see if you still earn rewards if you request a balance transfer or cash advance.
  • Stay on top of your bills. If you pay your credit card bill late–or worse, don’t pay it at all–you may owe additional fees. Those fees can add up quickly, increasing your balance and, in turn, your interest charges. When the money you owe far exceeds your rewards, you don’t get to enjoy your cash back. If your credit score suffers, you may not qualify for the best credit card in the future.
  • Choose the best credit card. The best way to choose a cash back card is to compare rewards categories and see which card gives the most cash rewards for the categories you spend the most money in. For example, if you find yourself running to the store for your family each week, you may want a card with a groceries bonus category. On the other hand, if you frequently commute a long way for work, a card that rewards you extra for gas purchases may be the best fit for you.

You may also consider factors like fees (including annual fees) and interest rates. If you often carry a balance on your card, make sure the interest you’re paying won’t offset any cash back reward. If your credit score isn’t as high as you’d like it to be, you may also compare cards to find one you qualify for.

Did you know?

You don’t always need a high credit score to qualify for a cash back card. With a secured credit card from Discover, you could earn 2% Cashback Bonus® at gas stations and restaurants on up to $1,000 in combined purchases each quarter, automatically. Plus earn unlimited 1% cash back on all other purchases.2

Cash back vs. miles

Like cash back, miles are another popular credit card reward. A travel credit card may offer a certain number of miles per dollar spent. Some cards may also offer additional miles for travel-related purchases, like flights or hotels. Once you earn a certain number of miles, you can redeem them toward flights or other travel-related purchases. The value of miles may change depending on the airline, rewards program, and cost of flights or hotels.

With the Discover it® Miles Card, cardmembers earn unlimited 1.5x Miles automatically on travel purchases and all your everyday purchases.4 Then you can turn Miles into cash. Or redeem as a statement credit for your travel purchases like airfare, hotels, rideshares, gas stations, restaurants and more.5

Both cash back and miles can be valuable rewards. The right fit for you depends on your shopping habits and priorities. Globetrotters may find that a travel credit card brings them more value. However, a cash back reward card may provide more flexibility for how much you earn and what you can redeem your rewards for.

Advantages and disadvantages of cash back

If you’re considering a cash back credit card, it’s important to keep in mind not only the obvious advantage—earning rewards as you shop—but also other perks and disadvantages, too. The following are some pros and cons of cash back. While they may not all apply to every card, they could still provide you with guidance as you compare the best cash back cards for your needs.

Pros of cash back rewards

  • Introductory offers could help you earn even more cash back.
  • Cash back rewards offer flexibility–spend them however you’d like.
  • Earning rewards is easy. You automatically receive cash back as you use your card.
  • You could incorporate cash back into your monthly budgeting strategy by planning purchases around rewards categories.
  • Cash back may encourage responsible credit card use, since fees and interest could eat into what you earn in rewards.

Cons of cash back rewards

  • While Discover doesn’t charge annual fees, other cash back credit cards might. It’s important to make sure you earn enough cash rewards to counterbalance annual fees.
  • If you have a bad credit score, you may not qualify for certain cash back credit cards.
  • Rewards credit cards may come with higher interest rates than other cards, which makes it especially important to minimize your balance, or avoid interest altogether by paying your balance in full and on time each month.
  • Some transactions, like a cash advance, may not earn rewards.

Navigating the fine print: terms, limitations, and expirations

Even if you find what seems like the perfect cash back credit card for your financial situation, it’s important to understand the terms. Terms and conditions usually include information about interest rates, penalties and transaction fees, credit limits, expiration dates, reward rates, and more. Of course, credit card agreements aren’t always easy to understand. The following could help you make sense of the fine print.

Where to find terms and conditions

When you’re applying for a credit card online, you may see a link that says “terms and conditions,” “offer details,” or “rates and disclosures.” Here, you should be able to find information about the rewards program and other vital details. According to the Consumer Financial Protection Bureau, your credit card issuer is required to provide you with a copy of your credit card agreement. You can also find credit card terms in a Schumer box on your credit card statements. However, Schumer boxes don’t contain information on your rewards rates and exclusions.

Deciphering cash back terms

Here are a few names or phrases that might appear in your terms and conditions. Check with your credit card issuer for your exact terms.

 

  • Annual Percentage Rate (APR): The rate at which your credit card balance will accrue interest over time. Many cards have a variable interest rate, meaning it may change based on the market. 
  • Penalty APR: The rate at which your credit card balance will accrue interest if you miss a payment. Card issuers often charge a higher rate on transactions if you miss a payment. Sometimes, your APR returns to normal after several on-time payments. 
  • Reward category rules: If your card offers rewards in certain broad categories like “travel expenses,” this section defines those categories and lists the specific transactions that count towards them.  
  • Reward exclusions: Some types of transactions may not qualify for cash back, depending on your credit card. For example, a balance transfer won’t earn cash back with Discover. Likewise, some types of purchases that seem like they’d fall within certain bonus categories may not, depending on your card issuer (like gas from a supermarket instead of a gas station).

Expiration and forfeiture

With some credit card issuers, you lose your cash back rewards if you don’t use them. The FDIC explains that credit card rewards may expire if cardmembers don’t redeem them within a specific time frame. Similarly, if a credit card account remains inactive for a certain amount of time, you may also forfeit or lose all the cash back you’ve earned on that account. While these conditions aren’t exactly the same, it’s important to understand them both so you can avoid losing your hard-earned cash back.

The future of cash back programs

As consumers’ financial priorities and situations change, so do credit card cash back programs. The CFPB’s 2023 Consumer Credit Market Report points to some trends that may impact the future of cash back programs.

 

In the U.S., credit card rewards earned have risen each year since 2020. The average reward rate per dollar spent has increased as well. Welcome offers have made up an increasing portion of overall rewards earned. That may lead to more robust welcome offers in the future as credit card companies compete for consumers. 

 

Credit card issuers have also increasingly incentivized virtual wallets, sometimes offering bonus cash back for cardholders who take advantage of this tool. In the future, credit card companies may further highlight digital financial products.

 

No matter what the future holds for cash back, responsible credit card use remains vital for earning the most rewards and maintaining a healthy credit score.

Cash back is a popular credit card reward because it offers flexibility and lets you earn with ease. If you’re considering a cash back rewards card, paying attention to the rewards rate, annual fee, eligibility requirements, and restrictions could help you make the most informed choice.

  1. Rewards Redemption: Rewards never expire. We reserve the right to determine the method to disburse your rewards balance. We will credit your Account or send you a check with your rewards balance if your Account is closed or if you have not used it within 18 months. You may be unable to redeem rewards in some limited situations such as when you choose to use an electronic funds transfer to redeem rewards to a new (unverified) deposit account.

  2. You earn a full 2% Cashback Bonus® on your first $1000 in combined purchases at Gas Stations (stand-alone), and Restaurants each calendar quarter. Calendar quarters begin January 1, April 1, July 1, and October 1. Purchases at Gas Stations and Restaurants over the quarterly cap, and all other purchases, earn 1% cash back. Gas Station purchases include those made at merchants classified as places that sell automotive gasoline that can be bought at the pump or inside the station, and some public electric vehicle charging stations. Gas Stations affiliated with supermarkets, supercenters, and wholesale clubs may not be eligible. Restaurant purchases include those made at merchants classified as full-service restaurants, cafes, cafeterias, fast-food locations, and restaurant delivery services. Purchases must be made with merchants in the U.S. To qualify for 2%, the purchase transaction date must be before or on the last day of the offer or promotion. For online purchases, the transaction date from the merchant may be the date when the item ships. Rewards are added to your account within two billing periods. Even if a purchase appears to fit in a 2% category, the merchant may not have a merchant category code (MCC) in that category. Merchants and payment processors are assigned an MCC based on their typical products and services. Discover Card does not assign MCCs to merchants. Certain third-party payment accounts and digital wallet transactions may not earn 2% if the technology does not provide sufficient transaction details or a qualifying MCC. Learn more at Discover.com/digitalwallets. See Cashback Bonus Program Terms and Conditions for more information.

  3. Cashback Match: We’ll match all the cash back you’ve earned on your credit card from the day your new account is approved through your first 12 consecutive billing periods or 365 days, whichever is longer, and add it to your rewards account within two billing periods. You earn cash back only when they’re processed, which may be after the transaction date. We will not match: rewards that are processed after your match period ends; statement credits; rewards transfers from Discover checking or other deposit accounts; or rewards for accounts that are closed. This offer may not be available in the future and is exclusively for new cardmembers. No purchase minimums.

  4. Each Mile is equal to $0.01. Starting at 1 Mile you can apply Miles as credit to your account to pay for all or part of your statement, for cash as an electronic deposit to your bank account, or for a credit for Travel Purchases made on your statement within 180 days. Miles cannot be redeemed directly with a specific airline carrier. See Terms and Conditions for more information.

  5. Redeem Miles: Starting at 1 Mile, you can redeem your Miles as a credit to your account to pay for all or part of your bill, for cash as an electronic deposit to your bank account, or for a credit for Travel Purchases made on your statement within the last 180 days. Each Mile is equal to $0.01. Miles cannot be redeemed directly with a specific airline carrier. Travel Purchases include airline tickets, hotel rooms, car rentals, travel agents, online travel sites, commuter transportation, restaurants and gas stations. Restaurant purchases include those made at merchants classified as full-service restaurants, cafes, cafeterias, fast-food locations, and restaurant delivery services. Gas Station purchases include those made at merchants classified as places that sell automotive gasoline that can be bought at the pump or inside the station. Gas Stations affiliated with supermarkets, supercenters, and wholesale clubs may not be eligible.

    Even if a travel purchase on your statement appears to fit in a Travel Purchase category, the merchant may not have a merchant category code (MCC) in a Travel Purchase category. Merchants and payment processors are assigned an MCC based on their typical products and services. Discover Card does not assign MCCs to merchants. Certain third-party payment accounts and digital wallet transactions may not be eligible for credit redemption if the technology does not provide sufficient transaction details or a qualifying MCC. See Terms and Conditions for more information.

  6. There is no hard inquiry to your credit report to check if you’re pre-approved. If you’re pre-approved, and you move forward with submitting an application for the credit card, it will result in a hard inquiry which may impact your credit score. Receiving a pre-approval offer does not guarantee approval. Applicants applying without a social security number are not eligible to receive pre-approval offers. Card applicants cannot be pre-approved for the NHL Discover Card.
