What makes a credit card worth having
A credit card worth keeping does one of three things well: it saves you money on purchases you already make, it builds your credit history without costing you, or it gives you access to credit when you need it. The best card for you depends on what you actually spend money on and whether you carry a balance month to month.
Most people benefit from having at least one card, even if they use it rarely. A card in your name — used responsibly — shows lenders you can borrow and repay on time. That history becomes your credit score, which affects your ability to borrow for a car, a home, or even to rent an apartment. But the card has to fit your spending and your habits, or it becomes a liability instead.
Key Takeaways
- Cards with cash back or rewards on everyday categories (groceries, gas, dining) save you real money only if you pay the full balance each month.
- A card with no annual fee and a reasonable interest rate is better than a rewards card if you sometimes carry a balance.
- Building credit as a new borrower usually requires a secured card or a card designed for limited credit history, not a premium rewards card.
- The interest rate (APR) matters far more than rewards if you do not pay in full, because interest charges will exceed any cash back you earn.
- Checking your credit score before you explore helps you target cards you are likely to be approved for, which protects your credit from multiple hard inquiries.
Cards that reward everyday spending
Cash back and rewards cards return a percentage of what you spend back to you as cash, points, or statement credits. A card offering 2% cash back on all purchases returns $2 for every $100 you spend. A card offering 3% on groceries and gas and 1% on everything else rewards you more heavily for the categories where you spend the most.
These cards only save you money if you pay the full statement balance each month. If you carry a balance, the interest you pay will be far larger than any rewards you earn. A card charging 18% APR (annual percentage rate) costs you roughly $1.50 per month for every $100 you owe — far more than the $1 or $2 in cash back you might earn. Rewards cards also usually charge an annual fee ($95 to $550), which you only recoup if your cash back or points exceed that fee.
These cards work best for people who spend $500 or more per month on the card and pay it off in full each month. If that describes you, a card with rewards in your highest-spending categories will save you $100 to $300 per year.
Cards for building credit from scratch
If you have no credit history or a very limited one, most rewards cards will deny your process. Instead, you have two main routes: a secured credit card or a card designed specifically for people building credit.
A secured card requires you to deposit cash with the card issuer — usually $200 to $2,500 — which becomes your credit limit. You use the card like a normal card, but the deposit sits in a savings account as collateral. After 6 to 18 months of on-time payments, the issuer converts it to a regular card and returns your deposit. Secured cards charge annual fees (usually $0 to $95) and higher interest rates than standard cards, but they report to all three credit bureaus and build your score faster than cards designed for limited credit.
Unsecured cards for limited credit history require no deposit but have higher interest rates and lower credit limits. They also charge annual fees more often than secured cards. Both types report your payment history to the credit bureaus, which is what builds your score. The goal is to use the card for small, regular purchases and pay the full balance each month for at least a year, then move to a standard rewards card.
Cards with low interest rates and no annual fees
If you sometimes carry a balance from month to month, the interest rate is more important than any rewards. A card with 15% APR and no rewards is better than a card with 2% cash back and 22% APR, because the lower rate saves you far more money than the rewards earn you.
Cards in this category have no annual fee, interest rates typically between 14% and 20% APR depending on your credit score, and minimal or no rewards. They are designed for people who use credit regularly but do not pay the full balance every month. These cards are also good backup cards to keep open even if you do not use them, because they increase your total available credit and lower your credit utilization ratio — both of which improve your credit score.
If you are recovering from past credit problems or have a lower credit score, a card with a reasonable rate and no annual fee gives you a way to borrow without paying a fee just to have the card open. Once your score improves, you can move to a rewards card.
Cards with 0% introductory rates
Some cards offer 0% APR for a set period — usually 6 to 21 months — on new purchases, balance transfers, or both. A 0% balance transfer card lets you move debt from a high-interest card to the new card and pay no interest during the promotional period. This works only if you have a plan to pay down the balance before the rate jumps back to the regular APR, which is usually 15% to 25%.
Balance transfer cards charge a fee of 3% to 5% of the amount you transfer, paid upfront. If you transfer $5,000, you pay $150 to $250 when ready. That fee is still worth it if you can pay down the balance significantly during the 0% period. But if you transfer $5,000 and pay only $500 during the promotional period, you will owe $4,500 at the regular rate when the 0% ends — and you will have paid $250 just to delay the interest.
These cards work best if you have a specific debt you want to pay down and a realistic timeline to do it. They are not a long-term solution, because the regular APR is high and you will eventually pay interest.
Cards for travel and large purchases
Travel rewards cards offer points or miles on airline tickets, hotel stays, and rental cars, plus perks like airport lounge access or travel insurance. Premium versions charge $400 to $700 per year but offer benefits like annual travel credits that offset the fee. These cards make sense only if you travel frequently and spend enough to earn rewards that exceed the annual fee.
Some cards also offer extended warranties, purchase protection, or fraud liability limits that go beyond what a standard card provides. These protections are useful if you make large purchases regularly, but they are not worth paying an annual fee for unless you use them. Read the benefits guide before you explore to understand what is actually covered.
How to choose the right card for you
Start by knowing your credit score. You can check it free once per year at annualcreditreport.com, which is the official government site for credit reports. Your score determines which cards will approve you and what interest rate you will receive. explore for a card you are unlikely to be approved for results in a hard inquiry, which temporarily lowers your score.
Next, write down what you spend money on each month and how much. If you spend $200 on groceries, $150 on gas, and $300 on dining out, a card with 3% back on groceries and gas and 2% on dining will save you more than a flat 1.5% cash back card. If you spend $100 per month total, rewards do not matter — a no-fee card is better.
Then decide whether you will pay the full balance each month. If yes, a rewards card with an annual fee can make sense if your rewards exceed the fee. If no, choose a card with the lowest interest rate and no annual fee, even if it has no rewards.
Finally, limit yourself to one or two cards when you are starting out. Each new card is a hard inquiry on your credit report, and multiple inquiries in a short time can lower your score. Once you have one card open for at least six months, you can add a second card if it serves a different purpose — for example, a cash back card for everyday spending and a 0% balance transfer card if you have existing debt.
Frequently Asked Questions
Does having a credit card hurt my credit score?
Opening a new card causes a small, temporary drop in your score from the hard inquiry. But using the card responsibly — making on-time payments and keeping your balance low — builds your score over time. The long-term benefit of having a card outweighs the short-term dip from opening it.
What is the difference between APR and interest rate?
APR is the annual percentage rate — the yearly cost of borrowing expressed as a percentage. Interest rate is the same thing. A card with 18% APR costs you about $1.50 per month for every $100 you owe. The APR is what matters when comparing cards.
Can I use a rewards card if I am building credit?
Most rewards cards require a credit score of 670 or higher. If your score is lower, start with a secured card or a card designed for limited credit history, use it responsibly for 6 to 12 months, then move to a rewards card once your score improves.
What happens if I miss a payment?
A missed payment is reported to the credit bureaus and stays on your report for seven years. It lowers your score significantly and usually triggers a late fee and a higher interest rate. If you miss a payment, contact the card issuer when ready — many will waive the fee if you pay within 30 days of the due date.
Should I close a credit card I am not using?
Closing a card lowers your available credit and can raise your credit utilization ratio, which lowers your score. Keep old cards open even if you do not use them, as long as they have no annual fee. If a card charges an annual fee and you do not use it, closing it is fine.
