Cashback is money returned to you based on what you spend

Cashback is a percentage of your purchase amount that a credit card issuer or retailer gives back to you. When you buy something with a cashback card, the card company or store tracks the transaction, calculates the reward (usually 1% to 5% of the purchase price), and credits that amount to your account. You receive the money as a statement credit, a check, or a deposit to a linked bank account — the method depends on which card or program you use.

The cashback comes from the merchant fees that retailers pay to card networks. When you swipe a credit card, the store pays a processing fee (typically 2% to 3% of the sale). Card issuers use part of that fee to fund rewards programs. This is why cashback exists: the card company makes money from the transaction volume and can afford to return some of it to you.

Cashback is not the same as a discount. A discount reduces what you pay at checkout. Cashback is credited later — sometimes days or weeks after the purchase — and you must track it or actively redeem it depending on the card.

Key Takeaways

  • Cashback rates vary by card and category, ranging from flat 1% on all purchases to 5% or higher on specific spending like groceries or gas.
  • You must use the card to make the purchase; cashback does not apply to transactions made with other payment methods.
  • Cashback is credited to your account periodically (monthly or quarterly) and can be taken as a statement credit, deposited to a bank account, or redeemed for gift cards depending on the card issuer.
  • Annual fees on some cashback cards can offset the rewards you earn, so compare the fee against your expected annual cashback.
  • Cashback is taxable income in the year you receive it, though most card issuers do not report small amounts to the IRS.

Flat-rate versus category cashback

A flat-rate cashback card returns the same percentage on every purchase. Common rates are 1%, 1.5%, or 2% on all spending. These cards are straightforward: you spend, the percentage is applied automatically, and you do not have to track which purchases may have access to. Flat-rate cards work well if you do not want to think about which card to use for each transaction.

A category cashback card returns different percentages depending on what you buy. You might earn 5% on groceries, 3% on gas, 2% on dining, and 1% on everything else. Some cards rotate categories quarterly (for example, 5% on a different category each season), and you must activate the category to earn the higher rate. Category cards reward you more if you spend heavily in those categories, but they require you to remember which card to use and to activate rotating categories.

A few cards combine both: a flat rate on all purchases plus bonus categories. For example, 1.5% on everything plus 3% on dining. Read the card terms to see whether categories have spending caps — many cards limit 5% cashback to the first $1,500 spent per quarter, then drop to 1% after that.

How cashback is credited and when you receive it

Cashback accrues as you make purchases but is not immediately available. Most card issuers credit cashback monthly or quarterly. You can see the pending amount in your online account before it is credited. Once credited, you have several options for how to use it.

The most common method is a statement credit: the cashback is applied directly to your credit card balance, reducing what you owe. This happens automatically on many cards. Some issuers let you choose when to redeem, while others apply it automatically at the end of each month or quarter.

Other redemption methods include direct deposit to a linked bank account, a check mailed to your address, or conversion to gift cards or travel rewards. A few cards let you donate cashback to charity. Check your card's redemption options in the cardholder agreement or online account portal.

Cashback does not expire on most cards, but some issuers have rules: for example, cashback may be forfeited if your account is closed or if you do not redeem within a certain period. Read the terms to know whether your cashback has an expiration date.

Annual fees and whether cashback is worth it

Many cashback cards charge an annual fee, ranging from $95 to $550 or more. A card with a $95 annual fee only makes financial sense if you earn at least $95 in cashback per year. If you spend $5,000 annually on a 2% flat-rate card, you earn $100 in cashback — enough to cover a $95 fee. If you spend less, the fee costs you money.

Cards with no annual fee typically offer lower cashback rates (often 1% flat) but are worth using if you carry a balance or do not spend enough to justify a fee. Cards with annual fees usually offer higher rates or bonus categories, making them worthwhile only if your spending is high enough.

To decide whether a card is worth the fee, calculate your expected annual cashback based on your typical spending, then subtract the annual fee. If the result is positive, the card saves you money. If it is negative or close to zero, a no-fee card is the better choice.

Cashback on different types of purchases

Cashback applies to most credit card purchases: groceries, gas, dining, travel, online shopping, and retail stores. However, some transactions do not earn cashback. Balance transfers (moving debt from one card to another) typically earn no cashback. Cash advances (withdrawing cash from an ATM using your credit card) also do not earn rewards and usually carry a fee and higher interest rate.

Payments to other credit cards, loan payments, and utility bills may or may not earn cashback depending on the card issuer and the payment method. Paying your electric bill online with a credit card might earn cashback, but paying through the utility company's website with a credit card might not. Paying your mortgage or car loan with a credit card usually does not earn cashback and may trigger a cash advance fee.

Some retailers and payment platforms block rewards-earning transactions. For example, some grocery stores and gas stations code transactions in ways that prevent cashback from posting. If you notice cashback is missing from a purchase you expected to earn on, contact the card issuer to ask why.

Cashback and your credit score

Using a cashback card does not directly harm your credit score. However, how you use the card does. Your credit score is based on payment history (35%), credit utilization (30%), length of credit history (15%), credit mix (10%), and new inquiries (10%).

Carrying a high balance on a cashback card increases your credit utilization ratio, which can lower your score. If you spend $5,000 on a card with a $10,000 limit, your utilization is 50%, which is high. Paying off the balance in full each month keeps utilization low and protects your score.

Opening a new cashback card triggers a hard inquiry, which temporarily lowers your score by a few points. If you open multiple cards in a short time, the impact is larger. The inquiry falls off your report after two years and stops affecting your score after one year.

Cashback and taxes

Cashback is considered taxable income by the IRS. In theory, you should report it on your tax return. However, most card issuers do not report cashback to the IRS unless the amount is unusually large (generally over $20,000 in a year). If your cashback is small — a few hundred dollars — it is unlikely to be reported, but you are technically required to claim it.

Keep records of your cashback earnings if you want to be thorough. Your online account shows annual totals, and you can download statements. If you are audited, the IRS may ask about unreported income, and having documentation protects you.

Cashback on business credit cards may have different tax treatment. If you use a business card, consult a tax professional about how to report the rewards.

Frequently Asked Questions

Can I earn cashback on a debit card?

Some debit cards offer cashback, but the rates are usually much lower than credit cards — often 0.5% or less. Debit card cashback is less common because debit transactions generate lower merchant fees than credit transactions. Credit cards are the primary way to earn meaningful cashback.

What happens to my cashback if I close the card?

Cashback that has already been credited to your account is yours to keep. However, pending cashback that has not yet been posted may be forfeited when you close the card. Redeem or request a statement credit for any pending balance before closing the account.

Do I have to pay interest on purchases to earn cashback?

No. Cashback is earned on the purchase amount regardless of whether you pay the balance in full or carry it forward. However, if you carry a balance, interest charges will exceed the cashback you earn, so paying in full is the better financial choice.

Can I combine cashback with other promotions or discounts?

Yes, in most cases. You can use a cashback card to make a purchase that is already on sale, and you earn cashback on the discounted price. Some retailers offer additional rewards (points, loyalty discounts) that stack with credit card cashback. Check the retailer's terms to confirm.

How much cashback can I realistically earn in a year?

It depends entirely on your spending. If you spend $30,000 per year on a 2% flat-rate card, you earn $600. On a category card where you earn 5% on $10,000 in groceries and 3% on $8,000 in gas, you earn $740. The more you spend and the higher your cashback rate, the more you earn. Most people earn between $100 and $500 annually.
