Cashback is a percentage of what you spend that the card issuer gives back to you

When you use a cashback credit card, the card issuer — the bank or company that issued the card — pays you a small percentage of every purchase you make. If your card offers 2% cashback and you spend $100, you get $2 back. That money can show up as a credit on your statement, a deposit to your bank account, or points you redeem later, depending on the card.

The issuer can afford to do this because merchants pay them a fee every time you swipe the card — typically 2% to 3% of the transaction. The issuer keeps most of that fee and gives a portion back to you as cashback. You pay nothing extra for this. The price you see in the store is the same whether you pay cash or use the card.

Cashback is not a loan, a discount, or money the issuer is lending you. It is a reward for using their card instead of someone else's or paying with cash. You only receive it if you actually make the purchase.

Key Takeaways

  • Cashback is a percentage of your spending that the card issuer returns to you, usually between 1% and 5% depending on the card and category.
  • You only earn cashback on purchases you actually make — there is no cashback without spending, and you do not earn it on cash withdrawals or balance transfers.
  • Cashback appears as a statement credit, a bank deposit, or redeemable points, depending on your card's terms.
  • If you carry a balance and pay interest, the interest charges will almost always exceed the cashback you earn, so cashback works best when you pay your full statement balance each month.
  • Some cards offer higher cashback rates in specific categories like groceries or gas, and lower rates on everything else.

How cashback gets added to your account

The mechanics depend on your card's specific terms. Some cards deposit cashback directly into your linked bank account once a month or once a quarter. Others hold it as a statement credit that reduces your balance due. A third group converts it to points or miles that you then redeem for cash, gift cards, or travel.

Read your card's terms or log into your account to see which method yours uses. The issuer will tell you when cashback posts — some do it monthly, others quarterly, and a few only once a year. If you close the card before cashback posts, you may lose it, so check the timing before you cancel.

Most cards have no minimum cashback amount before it posts. A few require you to accumulate at least $1 or $5 before they deposit it. If your card has a minimum and you spend very little, cashback may sit in your account until you hit that threshold.

Flat-rate cards versus category cards

A flat-rate card gives you the same percentage back on every purchase. A card might offer 1.5% cashback on everything you buy, whether it is groceries, gas, or a plane ticket. These cards are simple: you do not have to remember which categories earn more, and you get the same reward no matter what you spend on.

A category card offers different rates depending on what you buy. A common structure is 5% back on groceries, 3% on gas, 2% on dining, and 1% on everything else. These cards reward you more for spending in categories the issuer thinks you will use frequently. The tradeoff is that you have to track which categories earn which rates, and you earn less on purchases outside those categories.

Neither type is automatically better. A flat-rate card makes sense if you spend evenly across categories or do not want to think about it. A category card makes sense if you spend a lot in one or two categories — say, you buy groceries every week but rarely eat out — and you remember to use the right card.

Why carrying a balance makes cashback pointless

Cashback only makes financial sense if you pay your full statement balance by the due date each month. Here is why: if you carry a balance, you pay interest. Credit card interest rates typically range from 18% to 25% per year, though they vary by card and your creditworthiness.

If you earn 2% cashback but pay 20% interest on a balance, you are losing money. The interest you pay will be roughly ten times larger than the cashback you earn. You would need to spend $10,000 to earn $200 in cashback, but if you carry a $5,000 balance for a year at 20% interest, you pay $1,000 in interest charges.

Cashback is a benefit for people who treat the card like a debit card — they spend money they already have and pay it off in full. If you are carrying a balance from month to month, the interest charges erase any reward value. In that situation, the priority is paying down the balance, not maximizing cashback.

What does not earn cashback

Cashback only applies to purchases. These transactions typically do not earn it:

  • Cash withdrawals at ATMs or from a teller
  • Balance transfers (moving debt from one card to another)
  • Fees (annual fees, late fees, foreign transaction fees)
  • Payments to the card itself
  • Some issuers exclude certain merchants, like casinos or money transfer services

Check your card's terms to see if there are other exclusions. Some cards also cap cashback — for example, they might offer 5% back on groceries but only up to $1,500 in grocery purchases per quarter. After you hit the cap, you earn 1% on additional grocery purchases that quarter.

How to actually use cashback

Once cashback posts to your account, what you do with it depends on how your card structures it. If it is a statement credit, it automatically reduces your balance due — you do not have to do anything. If it deposits to your bank account, it arrives like any other transfer. If it is points, you log into your account and choose what to redeem it for.

Some cards let you use cashback immediately, while others require a minimum balance before you can redeem. A few cards only let you redeem in specific ways — for example, as a statement credit but not as a bank deposit. Read your card agreement or the rewards section of your online account to see your options.

You can also choose to leave cashback in your account and let it accumulate. Some people do this to reach a redemption threshold or to save up for a larger reward. Just remember that if you close the card, you may forfeit any unredeemed cashback, so check the terms before you cancel.

Frequently Asked Questions

Do I have to spend a certain amount to earn cashback?

No. You earn cashback on every purchase, no matter how small. A $2 coffee on a 2% cashback card earns you 4 cents. The only exception is if your card requires a minimum cashback balance before it posts — for example, some cards only deposit cashback once it reaches $1.

Can I earn cashback on someone else's purchase if I pay with my card?

Yes. Cashback is tied to the card, not the person using it. If you lend your card to a family member or pay for a group dinner and they reimburse you, you still earn cashback on the full amount. The issuer does not care who made the purchase, only that the card was used.

What happens to my cashback if I close the card?

It depends on the issuer. Some let you keep cashback that has already posted, but you lose any cashback that has not posted yet. Others let you redeem pending cashback for a short window after you close the card. Check your card's terms or call the issuer before you cancel to find out what happens to your rewards.

Does cashback count as income for taxes?

The IRS generally does not treat cashback as taxable income because it is considered a rebate on your purchase, not a payment. You bought something for $100 and got $2 back, so your net cost was $98. However, if you receive a large amount of cashback from a business card or through a promotional offer, consult a tax professional to be sure.

Can I earn cashback on a debit card?

Some debit cards offer cashback, but it is much less common and usually lower than credit card cashback. Debit card cashback typically ranges from 0.5% to 1%, and it may only apply at specific merchants. Credit cards offer higher rates because the issuer makes money from merchant fees; debit card issuers do not have that revenue source.
