A cash rewards card gives you money back on purchases you make with that card

A cash rewards credit card is a card that returns a percentage of what you spend back to you as cash or a statement credit. You buy something for $100, the card gives you $1 or $2 or $5 back depending on the card's rate and the type of purchase. That money either lands in a rewards account you can redeem, or it automatically reduces your bill.

The catch is that the card issuer — the bank or company behind the card — makes money from the merchants who accept it. Those merchants pay a fee (usually 2 to 3 percent of the sale) to the card network and issuer. The issuer uses some of that fee to pay your cash back. If you carry a balance and pay interest, the issuer makes even more. Cash rewards cards are designed to attract people who pay off their balance each month, because those customers generate merchant fees without costing the issuer money in interest.

The card only makes financial sense if you pay the full balance every month. If you carry a balance, the interest you pay will almost always exceed the cash you earn back.

Key Takeaways

  • Cash rewards cards return 1 to 5 percent of your spending as cash or a statement credit, depending on the card and the purchase category.
  • You only benefit financially if you pay the full balance each month; carrying a balance means interest charges will exceed your rewards.
  • Some cards offer flat-rate rewards on all purchases, while others offer higher rates on specific categories like groceries or gas.
  • The card issuer pays for your rewards from fees that merchants pay, so the rewards are not "information programs" — they come from the cost of doing business.
  • Your credit score, income, and credit history determine whether you are approved and what interest rate and rewards rate you receive.

Flat-rate cards versus category cards

A flat-rate cash rewards card gives you the same percentage back on every purchase. A card might offer 1.5 percent cash back on everything you buy, whether it is groceries, gas, or a plane ticket. These cards are straightforward to use because you do not have to remember which categories earn more.

A category card offers different rates depending on what you buy. You might earn 5 percent back on groceries, 3 percent on gas, 2 percent on restaurants, and 1 percent on everything else. Category cards reward you more if your spending matches their categories, but they require you to track which card to use for which purchase. If you have multiple cards, you have to remember which one earns the most on groceries versus which one earns the most on travel.

Flat-rate cards work better if your spending is scattered or if you do not want to manage multiple cards. Category cards work better if most of your spending falls into one or two categories the card rewards heavily.

How to redeem your cash back

Cash back redemption works differently depending on the card. Some cards let you redeem your rewards balance whenever you want, even for small amounts like $25. Others require a minimum redemption, such as $50 or $100, before you can cash out. A few cards only let you redeem once a year.

The most common redemption methods are a statement credit (the rewards reduce your bill), a check mailed to you, a deposit to your bank account, or a gift card. Some cards let you choose; others lock you into one method. A statement credit is usually the fastest and simplest option because it happens automatically or with one click online.

Read the card's rewards terms before you open the account to understand the redemption rules. Some cards expire your rewards if you do not use them within a certain time period, though this is less common now.

Annual fees and when they make sense

Many cash rewards cards have no annual fee. You pay nothing to own the card, and you earn cash back on every purchase. These are the most straightforward option for someone new to rewards cards.

Some cards charge an annual fee — often $95 to $500 — but offer higher cash back rates or other benefits like travel insurance or airport lounge access. A card with a $95 annual fee might offer 2 percent cash back instead of 1.5 percent. Whether that trade-off makes sense depends on how much you spend. If you spend $10,000 a year, the extra 0.5 percent is $50 in additional rewards, which does not cover the $95 fee. If you spend $30,000 a year, the extra $150 in rewards exceeds the fee.

Do the math before you open a card with an annual fee. Calculate your expected annual spending, multiply it by the difference in cash back rates, and compare that to the fee. If the math does not work, a no-fee card is the better choice.

How cash rewards affect your credit score

Opening a cash rewards card affects your credit score in two ways. First, the card issuer runs a hard inquiry on your credit report, which temporarily lowers your score by a few points. Second, a new account lowers your average account age, which also lowers your score slightly. These effects usually fade within a few months.

Over time, a rewards card can help your score if you use it responsibly. Paying your balance in full each month shows lenders you manage credit well. Keeping the card open for years builds a longer credit history. The card also increases your total available credit, which lowers your credit utilization ratio (the percentage of your credit limit you are using) — and a lower utilization ratio improves your score.

The opposite happens if you carry a balance. High utilization and missed payments damage your score faster than the rewards help it. A rewards card is only a credit-building tool if you pay it off every month.

Comparing rewards cards to other ways to earn cash back

Cash rewards cards are not the only way to earn money back on purchases. Debit cards sometimes offer small cash back (usually 0.5 percent or less). Some checking accounts offer cash back on debit card purchases. Certain retailers offer their own rewards programs that are separate from credit cards.

The advantage of a credit card is that it usually offers higher rates (1 to 5 percent versus 0.5 percent) and works at any merchant that accepts the card network. A retailer rewards program might offer 5 percent back, but only at that one store. A debit card offers no fraud protection and no credit-building benefit.

If you already have a credit card you use responsibly, adding a cash rewards card is a low-cost way to earn more on spending you are already doing. If you do not have a credit card or you struggle to pay balances in full, a rewards card is not the right tool — the interest you would pay makes the rewards worthless.

What happens if you miss a payment or carry a balance

Missing a payment on a rewards card has the same consequences as missing a payment on any credit card. The issuer charges a late fee (usually $25 to $40 for a first offense), reports the missed payment to the credit bureaus after 30 days, and your interest rate may increase. A missed payment stays on your credit report for seven years and significantly damages your score.

Carrying a balance means you pay interest on the amount you owe. Interest rates on cash rewards cards typically range from 18 to 25 percent annually, though the exact rate depends on your credit score and the card issuer. If you carry a $1,000 balance at 20 percent interest, you pay roughly $200 in interest over a year. If that card earns 2 percent cash back, you would earn only $20 in rewards on $1,000 in spending — meaning the interest cost is ten times the reward benefit.

The only scenario where carrying a balance makes sense is if you are using a 0 percent introductory APR period (usually 6 to 21 months, depending on the card) to pay off existing debt from another card at a higher rate. Even then, you must have a plan to pay off the balance before the introductory period ends, or you will face the regular interest rate.

Frequently Asked Questions

Do I need good credit to get a cash rewards card?

Most cash rewards cards require good to excellent credit (a score of 670 or higher). If your score is lower, you may be denied or offered a card with a lower rewards rate. Some issuers offer cash rewards cards for people building credit, though the rates are usually lower (0.5 to 1 percent). Check the card issuer's website to see the credit range they typically approve.

Can I use a cash rewards card for large purchases to earn more cash back?

Yes, you can use the card for any purchase the merchant accepts. Some cards cap rewards on certain categories (for example, 5 percent cash back on groceries up to $1,500 per quarter, then 1 percent after that). Check the card's terms to see if there are spending caps. For large purchases, make sure you can pay the balance in full when the bill arrives, or the interest will erase the rewards benefit.

What if I have multiple cash rewards cards?

You can own multiple cards and use each one for the categories where it earns the most. For example, you might use one card for groceries (5 percent) and another for gas (3 percent). This strategy maximizes rewards but requires tracking which card to use for which purchase. Only do this if you can pay off all the cards in full each month.

Do cash rewards expire?

Most modern cash rewards cards do not expire your rewards balance. However, some cards may close your account if you do not use it for a long period (usually one to three years), which could forfeit your rewards. Check your card's terms. If you earn rewards but do not plan to use the card, redeem the balance before closing the account.

Is cash back the same as a discount?

No. A discount reduces the price before you pay. Cash back is money returned to you after you pay. If a store offers 10 percent off, you pay 90 percent of the price. If a card offers 2 percent cash back, you pay 100 percent of the price and receive 2 percent back later. Cash back is slower and requires you to remember to redeem it, but it works at any merchant that accepts the card.
