Cash-back credit cards: which kind pays, and for whom.

Almost every swipe in America now earns something. Since 2019, more than 90% of spending on general-purpose credit cards has been on rewards cards, according to the Consumer Financial Protection Bureau (CFPB). The rewards are real money. They are also paid for by somebody, and a 2023 Federal Reserve working paper estimated that about $15 billion a year moves through the card rewards system from some cardholders to others: from less financially sophisticated cardholders to more sophisticated ones, and on average from poorer, less educated areas to richer, more educated ones (Agarwal, Presbitero, Silva and Wix).

That is the first thing worth knowing about cash-back cards: they pay best for the people who never pay interest. The second is that the differences between good cards are smaller than the marketing suggests, and easy to work out. This guide does that arithmetic on one realistic household, shows where a category card or a card with a fee earns its place, and lists seven cards whose terms we read on the issuers' own sites. The cash back calculator runs the same arithmetic on your own spending.

The bar to clear: 2% on everything

Two widely available cards pay 2% on every purchase with no annual fee: the Wells Fargo Active Cash, which pays "unlimited 2% cash rewards on purchases," and the Citi Double Cash, which pays 1% when you buy and another 1% as you pay (Wells Fargo, Citi). Nothing to activate, no categories, no caps. Every other cash-back card has to beat 2% on your actual spending, after its fee, to justify the extra attention.

To see what that means in dollars we need a household. The Bureau of Labor Statistics published its 2025 Consumer Expenditure Survey results on October 29, 2026. The average household spent $6,491 on food at home, $4,142 on food away from home and $2,503 on gasoline and other fuels (BLS). We add utilities ($4,931), clothing ($2,010) and entertainment ($4,084) as the "everything else" a household might reasonably put on a card. That is $24,161 a year, about $2,013 a month, and it is the default in our calculator.

Two things stand out. The spread from the best card to the weakest is about $170 a year, real but not life-changing. And the only card that beats 2% as a household's single card does it by $13, because its 6% on groceries is offset by the 1% it pays on everything else. Category cards are specialists. Asked to do everything, they mostly lose to the generalist.

Where a category card earns its place: as the second card

The picture changes when a category card does only what it is good at. Put the same household's groceries and gas on the Blue Cash Preferred and everything else on a 2% card, and the groceries earn 6% on the first $6,000 instead of 2%. The calculator tries every pair of the seven cards; for this household the winner is exactly that split.

That is $170 a year more than a 2% card alone, and $265 more in the first year while the fee is waived (American Express). It costs a second card to track, and it depends on one number: how much you spend at U.S. supermarkets. Against a 2% card, the Preferred's 6% is worth four extra points on up to $6,000 a year. The $95 fee is covered at about $2,375 of supermarket spending a year, roughly $198 a month. Below that, the no-fee Blue Cash Everyday, at 3% on U.S. supermarkets, U.S. gas stations and U.S. online retail up to $6,000 a year each (American Express), paired with a 2% card earns $568 for this household with no fee at all.

The same logic applies to restaurants. Chase Freedom Unlimited pays 3% on dining, including takeout and eligible delivery, and on drugstores, and 1.5% on everything else (Chase). As a lone card it trails the 2% cards for our household; as a dining card beside one, it adds a point on every restaurant dollar. For a household that eats out a lot more than the average $345 a month, that can be the better second card.

Rotating categories: worth at most $240 a year

Chase Freedom Flex pays "5% cash back on up to $1,500 on combined purchases in bonus categories each quarter you activate," plus 3% on dining and drugstores and 1% on the rest (Chase). The categories change every quarter. The ceiling is easy to compute: four quarters of $1,500 at four points above the 1% base is $240 a year, and only if you remember to activate every quarter and the categories happen to match where you shop. For our household, the Flex earns $324 without the rotating categories and $564 with every quarter maxed. It rewards attention more than spending. That suits some people; be honest about whether it suits you.

The line that outweighs all of it: a carried balance

Rewards are paid on purchases. Interest is charged on what you don't pay off, and in August 2026 the Federal Reserve's average rate on card accounts that paid interest was 22.36% (G.19 via FRED). An average balance of $3,000 carried all year at that rate costs about $671. That is more than the best single card earns on our household's spending, and more than the best two-card pair.

The Federal Reserve paper found the mechanism behind that $15 billion. Rewards cards led less financially sophisticated cardholders to spend more and carry higher balances, and they tended to pay those balances down in ways that cost more interest. Its authors also found something less expected: banks charged lower interest rates on rewards cards than on comparable cards without rewards. The point isn't that rewards cards are a trap. It's that a card's rewards and its interest run on the same account, and the interest is usually the larger number.

If you are carrying a balance, the cash-back question can wait. The debt payoff calculator shows the cheapest order to clear several balances, and the balance transfer calculator shows whether a 0% card's fee is worth paying.

How to compare cash-back cards

1. Start from your statements, not the categories. Add up a few months of spending by type. A 6% category is worth nothing if you shop at a warehouse club the issuer doesn't code as a supermarket. Issuers decide what counts by the merchant's category code, not by what you bought.
2. Find the caps. Both Amex Blue Cash cards stop paying their supermarket rate at $6,000 a year; the Everyday caps gas and online retail the same way. The Flex's 5% stops at $1,500 a quarter. Above a cap, the card falls to 1%, and a 2% card is better.
3. Price the fee against the next-best card, not against nothing. A $95 card is worth it only for the extra it earns over the no-fee card you would otherwise use.
4. Check how the cash arrives. Citi pays the second 1% only as you pay the bill. Amex pays in Reward Dollars redeemed as a statement credit. In December 2024 the CFPB warned issuers that cutting the value of rewards already earned, or burying conditions in fine print, may be unfair or deceptive; plain cash back leaves less room for that than points do.
5. Treat a sign-up bonus as a one-time discount. When we checked, Wells Fargo offered $100 after $500 of purchases in three months on the Active Cash, and Chase $200 after $500 on the Freedom Unlimited. Count a bonus only if ordinary spending meets the requirement.
6. Mind the travel costs. The Blue Cash Preferred charges a 2.7% foreign transaction fee, more than its 1% base rate earns. Capital One says the Quicksilver charges none (Capital One).

Cards, with what we could confirm

Listed by fit for the most people, not by any payment to us. Terms were read on each issuer's site on October 31, 2026. Several issuers fill in APRs by script and their pages showed blanks or formula text; where that happened we print nothing rather than guess. Approval and your APR depend on your credit.

Who should skip rewards cards altogether, for now

Skip them if you carried a balance in any of the past few months, if a bigger credit line would tempt you to spend more, or if you are about to apply for a mortgage or car loan and would rather not add a new account and a hard inquiry first. For the first group, rewards are a rounding error next to interest. For the second, the Federal Reserve paper's finding is the warning: rewards cards nudge spending up.

They suit anyone who already pays the statement in full every month. For that person, a 2% card is close to free money, and a second category card is worth it only when the arithmetic above says so on their own spending. The calculator will tell you in a minute.

Questions people ask

What is the best cash-back credit card?

There isn't one for everybody. A no-fee card paying 2% on everything is the bar: on the average household's 2025 spending it earns about $483 a year. A category card beats it only if your spending in its categories is large enough to make up for the 1% or 1.5% it pays everywhere else, after any fee. Many households do best with a 2% card for everything plus one category card for groceries or dining.

Is the Amex Blue Cash Preferred worth the $95 annual fee?

It depends on your U.S. supermarket spending. Against a 2% card, its 6% earns four points more on up to $6,000 of supermarket purchases a year, so the fee is covered at about $2,375 a year, roughly $198 a month. On the average household's spending it earns about $592, or $497 after the fee, only $13 more than a 2% card if it is your only card. Used just for groceries and gas next to a 2% card, the pair earns about $653 after the fee.

Are rotating 5% categories worth it?

Only if you activate every quarter and spend near the cap. Chase Freedom Flex pays 5% on up to $1,500 a quarter in categories that change; the most that adds over its 1% base is $240 a year. With no rotating spending, the Flex earns about $324 on the average household's spending; at the full $1,500 every quarter, about $564.

Should I get a rewards card if I carry a balance?

No. At the Federal Reserve's August 2026 average rate of 22.36% on accounts charged interest, a $3,000 balance carried for a year costs about $671, more than any card here earns on an average household's spending. Pay the balance down first; a 0% balance transfer card may help.
