What cashback means and how you earn it

Cashback is a percentage of the money you spend that the credit card company gives back to you. When you use the card to buy something, the merchant pays the card issuer a fee (usually 2 to 3 percent of the purchase). The card issuer shares a portion of that fee with you as cashback.

The amount you earn depends on the card's cashback rate and what you bought. A card offering 1 percent cashback gives you $1 back for every $100 you spend. A card offering 3 percent cashback on groceries gives you $3 back for every $100 spent at grocery stores. Different cards have different rates for different categories—some offer higher cashback on gas or restaurants, lower on everything else, or a flat rate across all purchases.

You do not earn cashback on cash advances or balance transfers. You also do not earn it if you do not pay your bill. Most cards require you to pay at least the minimum balance each month to keep the account active, but cashback typically posts to your account whether you carry a balance or pay in full.

Key Takeaways

  • Cashback is a percentage of your spending that the card issuer returns to you, funded by the fees merchants pay when you use the card.
  • Different cards offer different rates for different categories—groceries, gas, restaurants, travel—so the card you choose affects how much you earn.
  • Cashback posts to your account monthly or quarterly, and you can usually redeem it as a statement credit, a check, or a deposit to a bank account.
  • Carrying a balance and paying interest erases the value of cashback, so the card only saves you money if you pay your full bill each month.
  • Some cards have an annual fee that can be higher than the cashback you earn, so compare the fee against your expected spending before opening the account.

When cashback posts and how to use it

Cashback does not appear in your account immediately after each purchase. Most cards post cashback monthly or quarterly—the card issuer batches all your may be able to access purchases from that period and credits the total to your account at once. You will see it listed on your statement as a credit or reward balance.

How you redeem it depends on the card. Most cards let you choose from three options: apply it as a statement credit (which reduces your bill), receive it as a check mailed to your address, or transfer it to a linked bank account. Some cards also let you use cashback to pay down your balance automatically, which happens at the end of each statement period. A few cards let you redeem cashback for gift cards or merchandise, though the value is usually lower than taking it as cash.

You do not have to redeem cashback immediately. It typically stays in your account until you request it, though some cards expire unused cashback after a set period—usually one to three years. Check your card's terms to see if there is an expiration date.

How card issuers decide what categories earn higher rates

Card issuers choose which categories to reward based on where they expect you to spend the most money and where they make the highest fees. Grocery stores and gas stations are common high-cashback categories because people spend regularly there and the fees are predictable. Travel and dining are also common because they generate higher fees per transaction.

The card issuer also uses categories to shape your behavior. A card offering 5 percent cashback on groceries but only 1 percent on everything else is designed to get you to use it for groceries and leave it at home for other purchases. This increases the card's share of your wallet and the total fees it collects.

Some cards offer a flat rate—1 or 2 percent on all purchases—instead of categories. These are simpler to use but usually earn less total cashback because the rate is lower. Cards with categories typically earn more if you spend heavily in the high-rate categories, but earn less if you spend mostly in low-rate categories.

The cost of carrying a balance versus the value of cashback

Cashback only saves you money if you pay your full statement balance each month. If you carry a balance, you pay interest on that balance, and the interest rate on credit cards is usually 18 to 25 percent per year. That interest erases the value of cashback almost immediately.

Here is a concrete example: you spend $1,000 on a card offering 2 percent cashback. You earn $20 in cashback. But if you carry that $1,000 balance for a month at 20 percent annual interest, you pay about $17 in interest that month alone. Over a year, you would pay $200 in interest on that $1,000 balance. The $20 cashback does not come close to covering it.

This is why cashback cards are only valuable for people who pay their bills in full each month. If you carry a balance regularly, a card with a lower interest rate or a 0 percent introductory period is a better choice than one with high cashback rates.

Annual fees and whether they are worth it

Many high-cashback cards charge an annual fee—typically $95 to $450—to cover the cost of the rewards they offer. You need to earn enough cashback to cover that fee for the card to be worth it.

If a card charges $95 per year and offers 2 percent cashback on all purchases, you need to spend at least $4,750 per year to break even ($95 divided by 0.02). If you spend less than that, you lose money. If you spend $10,000 per year, you earn $200 in cashback, which covers the $95 fee and leaves you $105 ahead.

Some cards waive the annual fee for the first year, which gives you a chance to see how much you actually earn before committing to paying it. Others waive the fee if you meet a spending threshold in the first three months. Read the card's terms carefully to understand when the fee applies and whether there are ways to avoid it.

How cashback differs from other rewards programs

Cashback is one type of credit card reward, but not the only one. Some cards offer points or miles instead, which you redeem for travel, merchandise, or statement credits. The difference is flexibility and value.

Cashback is the most straightforward because it is always worth the same amount—1 percent cashback is always 1 percent of your spending, no matter what you buy it with. Points and miles vary in value depending on what you redeem them for. A card offering 2 points per dollar spent might let you redeem 50,000 points for a $500 gift card (worth 1 cent per point) or for a flight that would have cost $800 (worth 1.6 cents per point). The value depends on your choice.

Cashback is also easier to use because you do not have to track redemption rates or hunt for good deals. You earn it, you redeem it, and you know exactly what it is worth. Points and miles require more attention but can be worth more if you know how to use them strategically.

Limits on cashback and how they work

Some cards cap how much cashback you can earn in a category each quarter or year. For example, a card might offer 5 percent cashback on groceries but only up to $1,500 per quarter, then 1 percent after that. Once you hit the cap, you earn the lower rate for the rest of the period.

These caps are usually high enough that most people do not hit them—$1,500 in groceries per quarter is $500 per month, which is above average household spending. But if you spend heavily in a category, it is worth checking whether the card has a cap and how high it is.

Some cards also require you to activate categories each quarter or year before you earn the higher rate. This means you have to log into your account and click a button to turn on 5 percent cashback for groceries, for example. If you forget to activate, you earn the base rate instead. Check your card's website or app to see if activation is required.

Frequently Asked Questions

Do I have to pay the card off in full to earn cashback?

No. Cashback posts to your account based on your purchases, not on how much you pay. But carrying a balance costs you interest that far exceeds the cashback you earn, so paying in full is the only way to actually benefit from the rewards.

Can I earn cashback on every purchase?

Most cards offer cashback on all purchases, but the rate varies by category. Some cards offer a flat rate on everything. A few cards exclude certain types of purchases like cash advances, balance transfers, or fees. Check your card's terms to see what is covered.

What happens to cashback if I close the card?

Cashback that has already posted to your account is yours to keep—closing the card does not erase it. But you will stop earning cashback once the account is closed. Redeem any remaining balance before you close the account.

Can I transfer cashback to another person?

No. Cashback is tied to your account and can only be redeemed by you. You cannot give it to someone else or transfer it to another cardholder on the same account.

Does cashback count as income for taxes?

No. The IRS treats cashback as a reduction in the price you paid for something, not as income. You do not report it on your tax return.
