What makes a credit card worth using
The best credit card for you depends on how you spend money and what you want in return — not on which card has the highest rewards rate in isolation. A card that pays 5% back on groceries means nothing if you spend $200 a year on groceries and $8,000 on gas. A card with no annual fee beats a card with a $500 annual fee only if the rewards you earn exceed what you pay.
The real comparison is between the rewards you will actually earn and the costs you will actually pay. That means starting with your own spending patterns, not with a ranked list of cards. Once you know where your money goes, you can match a card to that pattern.
Key Takeaways
- The best card for you depends on your actual spending — where you spend the most money, not where rewards rates are highest.
- Cards with annual fees make sense only if the rewards you earn in a year exceed the fee by a comfortable margin.
- Introductory 0% APR offers on purchases or balance transfers can save hundreds in interest, but only if you pay off the balance before the rate resets.
- Cashback cards are simpler than points-based cards: you know exactly what each dollar spent is worth, with no redemption tricks or expiration dates.
- Your credit score affects which cards you can open and what interest rate you will pay if you carry a balance.
Cashback cards: straightforward rewards on everyday spending
Cashback cards return a percentage of what you spend directly as cash or a statement credit. The math is transparent: 2% cashback means every $100 spent returns $2. There are no points to track, no redemption minimums, and no expiration dates on your rewards.
Most cashback cards fall into two categories. Flat-rate cards pay the same percentage on all purchases — typically 1.5% to 2% — and charge no annual fee. These work well if your spending is spread across many categories and you want simplicity. Tiered cards pay higher rates on specific categories (groceries, gas, restaurants, travel) and lower rates on everything else, often with an annual fee ranging from $95 to $550. Tiered cards only make sense if you spend enough in the high-reward categories to earn back the fee.
A concrete example: if a tiered card charges $95 annually and pays 3% on groceries but 1% on everything else, you need to spend roughly $6,300 on groceries per year just to break even on the fee. If your household groceries run $400 monthly, you hit that threshold. If they run $200 monthly, the flat-rate card saves you money.
Points and travel cards: higher rewards with more complexity
Points-based cards earn rewards that you redeem for flights, hotels, or merchandise rather than receiving cash. The value of a point varies depending on how you redeem it — the same point might be worth 1 cent if you redeem it for a gift card, but 1.5 cents if you book a flight through the card's travel portal. This variability makes the true value of your rewards harder to calculate upfront.
Travel cards often come with perks beyond points: airport lounge access, travel insurance, statement credits for baggage fees or Global Entry, and concierge services. These perks have real value only if you use them. A $450 annual fee makes sense if you fly frequently and use the lounge, but not if you fly once a year and never check a bag.
Points also expire or devalue over time. Some programs devalue points without warning, or require higher point balances to book the same flights. If you earn points but do not redeem them within a year or two, you may find they are worth less than when you earned them. Cashback avoids this problem entirely.
Introductory 0% APR offers: when they save money and when they do not
Many cards offer 0% annual percentage rate (APR) for a set period — typically 6 to 21 months — on purchases, balance transfers, or both. During that period, you pay no interest on the balance. Once the promotional period ends, the regular APR kicks in, usually 18% to 28%.
A 0% purchase offer is useful if you need to spread a large purchase over several months and want to avoid interest. A 0% balance transfer offer is useful if you carry debt on a high-interest card and want to move it to a card where you will not pay interest while you pay it down. The math is straightforward: if you owe $5,000 at 22% APR and transfer it to a card with 0% for 12 months, you save roughly $1,100 in interest — but only if you pay off the full $5,000 before the 12 months end.
The trap is carrying a balance past the promotional period. If you transfer $5,000 and pay down only $3,000 in 12 months, the remaining $2,000 suddenly accrues interest at 24% APR. You also lose any grace period on new purchases the moment you carry a balance. Many balance transfer offers also charge a fee upfront — typically 3% to 5% of the amount transferred — so factor that into your calculation.
Annual fees and when they are worth paying
A card with an annual fee is worth using only if the rewards you earn in a year exceed the fee. Some cards offset this with an annual statement credit — for example, a $95 fee paired with a $100 annual travel credit means you net $5 in value before earning any rewards. Others offer a first-year waiver, giving you time to test whether the card fits your spending.
Premium cards with fees of $300 or more target people who spend heavily and travel frequently. If you spend $100,000 a year across all categories and redeem points strategically, a $550 card might return $2,000 or more in value. If you spend $20,000 a year, that same card loses you money. The card issuer knows this — they are betting on your spending pattern matching their target customer.
No-annual-fee cards have become more competitive in recent years. Many offer 1.5% to 2% cashback with no strings attached. Unless a fee-based card's rewards or perks clearly exceed what you will pay, the no-fee option is usually the safer choice.
How credit score affects which cards you can open
Credit card issuers use your credit score to decide whether to approve you and what interest rate to offer. Cards with the best rewards and lowest fees typically require a score of 670 or higher, and the best cards often require 740 or above. If your score is below 670, you may be approved only for cards with higher interest rates, higher annual fees, or lower rewards rates.
Your credit score also determines your APR if you carry a balance. Two people approved for the same card might receive different interest rates based on their scores. Someone with a 780 score might get 18% APR, while someone with a 650 score gets 26% APR on the same card. Over time, this difference compounds significantly.
If your score is below 670, building it before opening a new card often saves you money. Paying down existing balances, correcting errors on your credit report, and making on-time payments for several months can raise your score enough to open a better card. The rewards you gain from a better card often exceed the interest you would pay on a weaker card.
Comparing cards: the questions that matter
When you are deciding between two cards, answer these questions in order. The first question eliminates most cards when ready.
Do you carry a balance month to month, or do you pay in full? If you carry a balance, the interest rate matters far more than rewards. A card with 18% APR and 2% cashback is worse than a card with 16% APR and 1% cashback — the interest you pay will dwarf the rewards. If you pay in full every month, the APR is irrelevant and rewards are the only factor.
What is your annual spending in each category? Add up what you spend on groceries, gas, restaurants, travel, and everything else. If a tiered card pays 3% on groceries and you spend $4,800 a year on groceries, that card earns you $144 in that category alone. If you spend $1,200 a year on groceries, it earns you $36. Use this to calculate whether a card's annual fee is worth it.
Will you actually use the perks? If a card offers airport lounge access but you fly twice a year, you will use the lounge maybe twice. If it offers a $200 annual travel credit but you do not book travel through the card's portal, you will not use it. Count only the perks you will actually redeem.
Frequently Asked Questions
Should I open multiple cards to maximize rewards?
Opening multiple cards can increase rewards if each card matches a different part of your spending. For example, one card for groceries, one for gas, one for everything else. However, each new card temporarily lowers your credit score and requires you to track multiple due dates. If you miss a payment on any card, the interest charges will exceed any rewards you earned. Start with one card that matches your largest spending category, then add a second only if you are confident you will manage both responsibly.
Is it better to use one card or multiple cards?
One card is simpler and less risky — you have one due date, one statement to track, and one relationship with a lender. Multiple cards earn more rewards if your spending is spread across categories that different cards reward. The trade-off is complexity and the risk of missing a payment. Most people are better off with one or two cards they use consistently than with five cards they manage poorly.
What happens to my rewards if I close the card?
Rewards you have already earned usually stay in your account and can be redeemed after you close the card. However, some cards expire rewards if you do not redeem them within a set time. Check your card's terms before closing it. Also, closing a card reduces your available credit, which can lower your credit score temporarily.
Can I negotiate the interest rate on my card?
You can call your card issuer and ask for a lower rate, especially if you have been a customer for years and have made all payments on time. Some issuers will lower your rate by a few percentage points. There is no harm in asking, but there is no may provide they will agree. If they refuse, your option is to transfer the balance to a card with a lower rate or a 0% promotional offer.
Does using a credit card hurt my credit score?
Opening a new card temporarily lowers your score because it creates a hard inquiry and lowers your average account age. Using the card responsibly — paying on time and keeping your balance low relative to your credit limit — raises your score over time. Carrying a high balance or missing payments will hurt your score significantly.
