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

When you use a cashback credit card, the issuer pays you back a small percentage of each purchase you make. That money goes into your account as a credit, a statement balance reduction, or sometimes a check. The percentage varies by card — commonly 1 percent on all purchases, or higher rates (2 to 5 percent) on specific categories like groceries, gas, or dining.

The card issuer funds this cashback from the merchant fee they collect when you swipe. When a store accepts your card, Visa or Mastercard charges the merchant roughly 1.5 to 3 percent of the sale. The issuer takes a cut of that fee and uses part of it to pay you cashback. This is why cashback cards often have annual fees or higher interest rates — the issuer is paying out money and needs to recover it somewhere.

Cashback only applies to purchases you actually make. It does not apply to balance transfers, cash advances, or fees like late charges. And you only receive it if your account is in good standing — most issuers will not pay cashback on a card that is in default or closed for fraud.

Key Takeaways

  • Cashback is calculated as a percentage of your purchase amount and credited to your account, usually monthly or when you request it.
  • Different cards offer different rates: flat rates (1 percent on everything) or category rates (5 percent on groceries, 1 percent elsewhere).
  • Cashback does not reduce what you owe if you carry a balance — it is a separate credit that appears on your statement.
  • You only earn cashback on may be able to access purchases; balance transfers, cash advances, and fees do not may have access to.
  • If you pay interest on a balance, the cost of that interest usually exceeds the cashback you earn, making the card a net loss.

How cashback is calculated and when it posts to your account

Cashback is calculated on the transaction amount, not on the final balance you pay. If you buy groceries for $100 on a card that offers 2 percent cashback on groceries, you earn $2 in cashback immediately — even if you do not pay the full $100 until later. The cashback is yours to keep regardless of whether you carry a balance or pay in full.

Most cards post cashback monthly, usually a few days after your statement closes. Some cards post it quarterly or annually. A few cards let you request cashback as a statement credit whenever you want, or they deposit it directly to a linked bank account. Check your card's terms or your online account to see when and how your cashback posts.

Cashback is not the same as a discount. A discount reduces the price you pay at the register. Cashback is credited to your card account after the purchase clears. If you return an item, the cashback for that purchase is reversed — you lose the $2 you earned on the $100 purchase if you return it.

Flat-rate versus category cashback cards

A flat-rate cashback card pays the same percentage on every purchase. Common rates are 1 percent, 1.5 percent, or 2 percent on everything. These cards are simple to use because you do not have to track which category a purchase falls into. You earn the same reward whether you buy gas, groceries, or a plane ticket.

A category cashback card pays higher rates on specific spending categories and a lower rate on everything else. For example, a card might offer 5 percent on groceries and gas, 3 percent on dining and travel, and 1 percent on all other purchases. These cards reward you for spending in categories where you naturally spend more money, but they require you to remember which categories earn which rates.

Category cards often have an annual cap on the higher rate. You might earn 5 percent cashback on groceries, but only on the first $1,500 spent per quarter — after that, you earn 1 percent. Check your card's terms for any caps, because once you hit the limit, your cashback rate drops for the rest of the period.

What happens to cashback when you carry a balance

Cashback does not reduce the interest you pay on a balance. If you owe $1,000 at 18 percent annual interest and earn $10 in cashback that month, you still owe the full $1,000 plus interest. The $10 cashback is a separate credit that appears on your statement, but it does not lower your balance or your interest charges.

In most cases, the interest you pay far exceeds the cashback you earn. If you carry a $1,000 balance at 18 percent interest, you pay roughly $15 in interest that month. Even a 2 percent cashback card earning $20 per month on $1,000 in new purchases does not offset the cost. The math only works in your favor if you pay your full balance every month and never carry interest.

Some cards let you use cashback to pay down your balance directly, which can save you interest. But this is optional — you have to choose to do it. By default, cashback is just a credit that sits in your account until you use it or request it as a statement credit.

Cashback redemption: how to use your earnings

Most cards let you redeem cashback in one of three ways: as a statement credit, as a deposit to a bank account, or as a check. A statement credit is the most common — your cashback automatically reduces your next bill or you can request it at any time. A bank deposit takes a few business days and requires you to link an account. A check is slower and less common but works if you prefer not to use digital transfers.

Some cards require a minimum cashback balance before you can redeem — often $25 or $50. If your card has a minimum and you have not reached it, your cashback sits in your account earning nothing until you hit the threshold. Once you redeem, the cashback is gone — you cannot earn cashback on cashback.

A few premium cards let you transfer cashback to travel partners or use it to book travel through the card's portal at a higher value. For example, $100 in cashback might be worth $150 in travel bookings. These options are rare and usually only on cards with annual fees of $300 or more.

Cashback and your credit score

Earning cashback does not affect your credit score. The reward itself is invisible to credit bureaus — they only see your payment history, credit utilization, and account age. Using a cashback card to make purchases and paying on time will build your credit, but the cashback earnings themselves play no role.

However, chasing cashback by overspending can hurt your score. If you increase your spending just to earn rewards, your credit utilization (the percentage of your credit limit you use) goes up. High utilization signals risk to lenders and can lower your score. The cashback you earn on extra spending is usually worth less than the damage to your score.

Common cashback card features and limits

Many cashback cards have annual fees ranging from $0 to $500. A card with no annual fee and 1 percent cashback is straightforward — you earn money with no cost. A card with a $95 annual fee and 2 percent cashback on everything needs to earn you at least $95 per year in cashback to break even. That means you need to spend at least $4,750 per year on the card.

Some cards cap your total cashback per year or per quarter. A card might offer unlimited 1 percent cashback with no cap, or it might cap 5 percent cashback at $500 per year. Once you hit the cap, you earn a lower rate or nothing at all for the rest of the period. Read the terms carefully to understand any limits.

Introductory offers are common on cashback cards. A new card might offer 5 percent cashback for the first three months, then drop to 1 percent. These offers are designed to attract new customers, not to reward long-term use. Calculate whether the card is still worth using after the intro period ends.

Frequently Asked Questions

Can I earn cashback on a purchase I return?

No. When you return an item, the original transaction is reversed, and the cashback you earned on it is removed from your account. If you earned $5 in cashback on a $250 purchase and return it, you lose the $5. Some cards may take a few days to reverse the cashback after the return is processed.

Does cashback count as income for taxes?

Cashback from a credit card is generally not taxable income. The IRS treats it as a rebate or discount on your purchase, not as income you earned. However, if you receive cashback in the form of a check or bank deposit, keep records of the amount in case you are audited. Cashback used as a statement credit is even less likely to trigger tax questions.

What is the difference between cashback and points or miles?

Cashback is a direct percentage return in dollars. Points and miles are a separate currency that you redeem for travel, merchandise, or statement credits, usually at a variable rate. Cashback is simpler because $1 in cashback is always worth $1. Points are harder to value because their worth depends on how and where you redeem them.

Can I use cashback to pay my credit card bill?

Yes, most cards let you apply cashback as a statement credit, which reduces your bill. Some cards do this automatically; others require you to request it. You cannot use unredeemed cashback to make a payment — you have to redeem it first, and then it appears as a credit on your account.

What happens to my cashback if I close the card?

Unredeemed cashback is usually forfeited when you close a card, though some issuers will let you redeem it within a short window after closure. Check your card's terms or contact the issuer before closing to find out whether you can keep your cashback. If you have earned cashback, redeem it before you close the account.
