The right card depends on what you spend money on, not on having "good" credit in general
A good credit card is one that pays you back for the things you already buy. If you fill up your gas tank twice a week, a card that returns 3% on fuel is better than one that returns 1% on everything. If you never carry a balance, a card with no annual fee and solid rewards beats one with a high fee and slightly better perks. If you travel once a year, a travel card makes sense; if you never leave your city, it does not.
The cards that work best are the ones matched to your actual spending pattern, not the ones with the longest list of features or the highest rewards rate in a category you do not use. This guide walks through the main card types, what each one costs, and which spending habits make each one worth having.
Key Takeaways
- Cash-back cards return a percentage of what you spend in specific categories — groceries, gas, restaurants — and work best if you spend heavily in those areas and pay off the balance each month.
- Travel cards offer points per dollar spent and often waive foreign transaction fees, but the annual fee (usually $95 to $550) only makes sense if you take multiple trips per year.
- Flat-rate cards give the same rewards percentage on all purchases and have lower or no annual fees, making them useful as a second card or if your spending is scattered across many categories.
- Store cards offer high rewards in one retailer but charge high interest rates if you carry a balance, so they work only if you pay in full each month.
- The card issuer matters as much as the card type — some companies process disputes faster, others have better fraud protection, and customer service quality varies widely.
Cash-Back Cards: Best if you spend heavily in specific categories
Cash-back cards return a percentage of your spending as cash or statement credits. Most offer different rates in different categories: 3% or 5% on groceries, 2% or 3% on gas, 1% on everything else. Some cap the amount you can earn in high-rate categories each quarter (often $1,500 to $2,500 in purchases), after which the rate drops to 1%.
These cards work best if your spending is concentrated. If you spend $400 a month on groceries and $300 on gas, a card returning 3% on groceries and 3% on gas earns you roughly $25 per month, or $300 per year. If the card has no annual fee, that is pure gain. If it charges $95 per year, you still come out ahead by $205.
Cash-back cards almost always require you to pay the full balance each month to make the math work. If you carry a balance, the interest you pay (typically 18% to 25% annually) will erase years of rewards. A $2,000 balance at 21% costs you $35 per month in interest alone — far more than any cash-back rate will return.
Travel Cards: Worth it only if you take multiple trips per year
Travel cards earn points per dollar spent on all purchases, then let you redeem those points for flights, hotels, or cash. They often waive foreign transaction fees (which run 2% to 3% on regular cards), offer travel insurance, and provide perks like airport lounge access or statement credits for baggage fees.
The catch is the annual fee. Most travel cards charge $95 to $550 per year. A card charging $95 needs to return at least $95 in value through points, fee waivers, or credits to break even. If you take one domestic flight per year and never use the lounge, you will not hit that threshold. If you take four international trips per year, the card likely pays for itself through points alone, plus you save 2% to 3% on every foreign transaction.
Travel cards also require discipline. Points expire if you do not use them within a set period (often three to five years), and redemption rates vary wildly — sometimes a point is worth less than a cent, sometimes more. Read the fine print on how points convert to actual dollars before you sign up.
Flat-Rate Cards: Useful as a second card or if your spending is scattered
Flat-rate cards return the same percentage on all purchases, usually 1.5% to 2%. They have no category limits and no annual fee (or a low one). They are simpler than category cards because you do not have to track which card to use for which purchase.
Flat-rate cards make sense in two situations. First, if your spending does not fit neatly into categories — you buy a lot of things that do not may have access to for bonus rates on your main card. Second, as a backup card when you are traveling or making a large purchase and want a straightforward way to earn rewards without thinking about which card to pull out.
The downside is that the rewards rate is lower than what you would get from a category card in your highest-spending categories. If you spend $6,000 per year on groceries and $4,000 on gas, a flat-rate card earning 1.5% returns $150. A category card earning 3% on groceries and 3% on gas returns $300 (before hitting category caps). The category card wins by $150 per year if it has no annual fee.
Store Cards: High rewards in one place, but only if you pay in full
Store cards are issued by individual retailers — Target, Amazon, Best Buy, Costco — and offer rewards only at that store. The rewards rate is often high: 5% back at the retailer, sometimes more during promotional periods. Some offer special financing (0% interest for 12 months on purchases over a certain amount).
Store cards are a trap if you carry a balance. The interest rates are among the highest in the credit card industry, often 24% to 29% annually. A $1,000 purchase at 27% costs you $270 in interest over a year if you make minimum payments. The 5% rewards ($50) disappear when ready.
Store cards make sense only if you shop at that retailer regularly and pay the full balance every month. If you buy $2,000 per year at Target and use a Target card earning 5%, you earn $100 per year. If you carry even a small balance, that math breaks down fast.
Issuer reputation and customer service matter more than you think
Two cards with identical rewards rates and annual fees can deliver very different experiences depending on who issues them. Some issuers process disputes in days; others take weeks. Some have fraud detection that flags legitimate purchases (and blocks them); others let fraud slip through. Customer service quality varies from excellent to nearly impossible to reach.
Before you open a card, look at reviews from current cardholders on sites like Trustpilot or the Better Business Bureau. Pay attention to complaints about dispute resolution, fraud handling, and how hard it is to reach customer service. A card that saves you $200 per year in rewards but takes three months to resolve a fraudulent charge is not a good deal.
Also check whether the issuer offers tools you actually use: a mobile app that works, the ability to set spending alerts, or the option to freeze your card temporarily if you lose it. These features do not show up in the rewards rate, but they matter when something goes wrong.
How to choose between cards you are considering
Start by listing your spending for the past three months across major categories: groceries, gas, restaurants, travel, subscriptions, and everything else. Add up how much you spend in each category per month, then multiply by 12 to get an annual total.
Next, look at the cards you are considering and calculate how much each would return on your actual spending. A card returning 3% on groceries and 1% on everything else is worth more to you if you spend $400 per month on groceries than if you spend $100. Do the math for your numbers, not the card's marketing numbers.
Then subtract the annual fee. If a card charges $95 per year and would return $300 in rewards on your spending, your net gain is $205. If it would return $80, your net loss is $15 — and you should skip it.
Finally, check the issuer's reputation for customer service and dispute handling. A card that wins on rewards but loses on reliability is not worth the risk.
Frequently Asked Questions
Should I close old cards after I open a new one?
No. Closing a card lowers your available credit and can hurt your credit 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 you do not want to pay, call the issuer and ask if they will convert it to a no-fee version of the same card.
What if I carry a balance sometimes but not always?
Avoid cards with high annual fees or high interest rates. Stick to flat-rate cards with no annual fee or low-fee cash-back cards. The interest you pay on a carried balance will almost always exceed the rewards you earn, so the card's rewards rate matters less than its interest rate.
Can I use multiple cards to maximize rewards?
Yes. Many people use one card for groceries, another for gas, and a flat-rate card for everything else. This works if you can track which card to use and pay all balances in full each month. If you struggle to manage multiple cards, stick to one or two.
Do I need a high credit score to get approved for a good rewards card?
Most premium rewards cards require a credit score of 700 or higher, and some require 750+. If your score is lower, start with a card designed for fair or good credit, build your score over time, and explore for premium cards later. The rewards difference is not worth the stress of repeated rejections.
What is the difference between points and cash back?
Cash back is straightforward: 1% back means $1 for every $100 you spend, credited to your account. Points are less clear — the issuer sets the redemption rate, so a point might be worth $0.008 or $0.015 depending on how you use it. Cash back is simpler and more predictable.
