What rewards credit cards actually do, and what they cost
A rewards credit card gives you cash back, points, or miles on purchases you make. The card issuer pays you a percentage of what you spend — often 1 to 5 percent depending on the category — and you can redeem those rewards for statement credits, gift cards, travel bookings, or cash. The catch is that most cards with good rewards charge an annual fee, usually between $95 and $550. You break even on that fee only if you spend enough to earn rewards that cover it.
The second cost is less obvious: if you carry a balance month to month, the interest you pay will almost always exceed the rewards you earn. A card offering 2 percent cash back is not a good deal if you are paying 18 percent interest on what you owe. Rewards cards work only if you pay your full statement balance every month.
The third consideration is that different cards reward different kinds of spending. A card that gives 5 percent back on groceries gives you nothing extra on gas or restaurants. Before you choose, look at where your money actually goes — not where you think it goes.
Key Takeaways
- Rewards cards only make financial sense if you pay off your full balance every month, because interest charges will erase any rewards you earn.
- Most good rewards cards charge an annual fee, so you need to spend enough in the right categories to earn back more than the fee costs.
- Different cards reward different spending categories, so the best card for you depends on whether you spend more on groceries, travel, gas, or dining.
- No-annual-fee cards exist and can be worth using if you spend little or want to avoid fees, but they typically offer lower rewards rates.
- Signing bonuses — large point or cash awards for meeting a spending target in the first months — can be worth hundreds of dollars but require you to spend more than you normally would.
Cards that reward everyday spending (groceries, gas, dining)
If most of your spending happens at the grocery store, gas pump, or restaurants, look for a card that gives high rewards in those categories. The Chase Freedom Unlimited offers 1.5 percent cash back on all purchases with no annual fee, which makes it a baseline option: you earn something on everything without paying to carry the card. The Capital One SavorOne also has no annual fee and gives 3 percent back on dining and entertainment, 1 percent on everything else.
If you are willing to pay an annual fee, the American Express Gold Card gives 4 percent back on groceries (up to $25,000 per year, then 1 percent) and 4 percent on restaurants and travel. The annual fee is $250, so you need to spend roughly $6,250 in those categories to break even. If you eat out often or buy groceries for a household, this math works. If you live alone and cook at home, it probably does not.
The Citi Custom Cash Card has no annual fee and gives 5 percent back on your highest-spending category each month (up to $500 in purchases, then 1 percent). This works well if your spending is uneven — some months you buy more groceries, other months more gas — because the card automatically tracks where you spend most.
Cards that reward travel spending
Travel rewards cards give high percentages back on flights, hotels, and rental cars, but the value depends on how you redeem. Some cards let you transfer points to airline or hotel partners at a fixed rate. Others let you book through the card's own travel portal, where the value of each point varies. A point might be worth 1 cent when you book a hotel directly, but only 0.5 cents when you book through the portal.
The Chase Sapphire Preferred charges $95 annually and gives 2 percent back on travel and dining, 1 percent on everything else. You can transfer points to airline partners or book through Chase's portal. The Chase Sapphire Reserve costs $550 per year but gives 3 percent on travel and dining, includes travel credits that offset part of the fee, and offers higher point values when you transfer to partners.
If you fly one airline consistently, a co-branded card from that airline often gives better rewards on that airline's flights and free checked bags. United, American, and Delta all offer cards at different fee levels. The trade-off is that these cards are less useful if you fly different airlines or rarely travel.
Cards with no annual fee
If you want to avoid paying a yearly fee, you have options, but the rewards rates are lower. The Chase Freedom Unlimited (1.5 percent cash back on everything) and the Capital One SavorOne (3 percent on dining and entertainment, 1 percent elsewhere) are both solid choices with no fee. The Discover it Cash Back gives 5 percent back on rotating categories that change each quarter — groceries, gas, restaurants, Amazon — but only up to $1,500 in purchases per quarter, then 1 percent. You have to set up each category each quarter, which takes two minutes online.
No-annual-fee cards make sense if you spend less than $3,000 per month, if you want to avoid fees entirely, or if you are new to credit cards and want to build a history without committing to an expensive card. They also work as a second card: you might use a premium card for travel and a no-fee card for everyday purchases.
How signing bonuses work and whether they are worth it
A signing bonus is a large award — often 50,000 to 100,000 points or $500 to $1,000 cash back — that you earn if you spend a certain amount in the first three months. The Chase Sapphire Preferred, for example, might offer 60,000 points (worth roughly $900 if transferred to an airline partner) if you spend $4,000 in the first three months.
The bonus is real money if you were going to spend that amount anyway. If you spend $4,000 per month normally, hitting $4,000 in three months means you are not changing your behavior — you are just getting paid for it. But if you normally spend $1,500 per month and you increase to $4,000 to chase the bonus, you are spending an extra $2,500 on things you did not need. That defeats the purpose.
Signing bonuses can also come with strings: some require you to spend the money on specific categories, and some require you to keep the card open for a year to keep the bonus if you later close the account. Read the terms before you explore.
Comparing cards side by side: what to actually look at
When you are deciding between two cards, build a straightforward table of your own spending. Write down how much you spend per month on groceries, gas, restaurants, travel, and everything else. Then calculate what each card would earn you per month in each category, subtract the annual fee divided by 12, and see which comes out ahead.
Example: You spend $400 per month on groceries, $200 on gas, $300 on restaurants, and $1,000 on everything else. The American Express Gold Card (4 percent on groceries and restaurants, 1 percent on everything else, $250 annual fee) would earn you roughly $24 per month on groceries, $12 on restaurants, $10 on other spending, minus $21 for the fee — about $25 per month net. The Chase Freedom Unlimited (1.5 percent on everything, no fee) would earn you roughly $24 per month. In this case, they are nearly equal, so the choice comes down to whether you want the extra 2.5 percent on restaurants and whether you trust yourself to pay off the balance every month.
This math only works if you are comparing cards you actually understand. Do not choose a card because someone online said it was the best. Choose it because you looked at your own spending and the rewards match where your money goes.
Red flags that a rewards card is not right for you
Do not open a rewards card if you carry a balance on any credit card. The interest you pay will be far larger than any rewards you earn. Pay down existing debt first, then open a rewards card once you can pay the full balance every month.
Do not open a card just because the sign-up bonus is large. If you have to spend money you would not otherwise spend to hit the bonus, you are losing money, not making it. The bonus only counts if it is on spending you were going to do anyway.
Do not open multiple cards at once to chase bonuses. Each process hits your credit report and can lower your score temporarily. Space applications out by at least a few months. Also, opening many cards in a short time can make lenders think you are in financial trouble and need cash, which can hurt your ability to borrow later.
Frequently Asked Questions
What is the difference between cash back and points?
Cash back is a percentage of your spending returned as dollars — 2 percent cash back on a $100 purchase is $2 credited to your account. Points are a currency you redeem for rewards, and their value depends on how you use them. A point might be worth 1 cent when you book travel through the card's portal, or 1.5 cents when you transfer it to an airline partner. Cash back is simpler; points can be worth more if you know how to redeem them.
Can I use a rewards card if I have fair or poor credit?
Most premium rewards cards require good or excellent credit (a score of 670 or higher). If your score is lower, you may not be approved. Start with a secured credit card or a basic card with no annual fee, build your score for six months to a year, then move to a rewards card once you are approved.
Do I lose rewards if I close the card?
You keep the rewards you have already earned, but you cannot earn new rewards once the card is closed. Some cards require you to keep the account open for a year after earning a sign-up bonus, or they will take the bonus back. Check the terms before you close an account.
What happens to my rewards if the card issuer changes the terms?
Card issuers can change rewards rates, categories, and annual fees, usually with 30 days' notice. You can close the card without penalty if you disagree with the change. Rewards you have already earned are not affected by future changes.
Is it better to have one rewards card or multiple?
Multiple cards can work if each one rewards a different category of your spending. You might use one card for groceries, another for travel, and a third for everything else. But managing multiple cards takes discipline — you have to track multiple due dates and make sure you pay each in full. If that sounds like too much work, one card that gives decent rewards across all categories is simpler and still worthwhile.
