Eighty-one percent of U.S. adults had a credit card in 2024, according to the most recent Federal Reserve data. This is an increase of five percentage points over the past decade, meaning more people today find themselves needing at least one credit card.

While the term “credit card debt” might carry a negative connotation, it’s not inherently bad or irresponsible to use credit cards for everyday spending, especially if you leverage points, miles or cash-back rewards. Just make sure you’re using your cards wisely by incorporating these smart habits every credit card user should know.

Some cards offer bonus rewards for things like gas or groceries, while others pay higher rates for travel-related purchases. Meanwhile, cards with rotating categories may allow you to choose where you earn rewards, or have preset choices that change monthly or quarterly. If you have multiple cards, keep a list of the bonus categories for each card so you can maximize your earnings.

In the case of travel rewards cards, you might be able to boost your earnings by booking through the card issuer’s travel portal rather than directly with the hotel or airline or through a non-affiliated third-party website.

Beyond cash-back rewards and points, many top-tier cards have additional benefits you’ll want to claim. Credit card perks can range from airport lounge access to cell phone insurance, purchase protection and price-drop guarantees. Read your card’s guide to benefits to understand the perks available to you.

Credit cards with a welcome bonus deliver a hefty reward when you meet a minimum spending requirement within the first few months of account opening. The time frame and spending thresholds vary depending on the card, so it’s important to keep track of the deadline.

If you’re planning a large purchase, it might be a good time to open a credit card and use the expense to help unlock a welcome bonus. However, look beyond the bonus and consider if  the card is a good fit for the long term. Card inactivity can lead to a credit limit decrease or even account closure, which can negatively affect your credit score.

Whether you carry top-tier rewards cards or you’re just getting started building your credit, it’s important to review your monthly statements or check your online accounts for fraud frequently. Most credit card companies offer zero fraud liability but only if you report unauthorized charges promptly.

Reviewing your statements will also help you spot unexpected fees or billing errors, and can help you keep track of your spending and budget.

In addition to reviewing your statements, set up email, text or app alerts with your credit card issuer so you’re aware of any purchases made. This can help you detect fraud early, as well as stay within your credit limit, especially if you have authorized users on the card other than yourself, such as a spouse or children.

Your credit utilization, or the amount of money you owe compared to your available credit, makes up roughly 30% of your FICO credit score. It’s best to keep this number under 30% on any individual card and across all credit cards.

For example, if you have a credit card with a $3,000 limit, try not to carry a balance of more than $900 on it at any given time. This helps out your credit score, your standing with issuers and your ability to pay off your cards before incurring interest.

Finally, avoid carrying a balance on your cards so you won’t get hit with credit card interest. Any rewards or benefits you might earn from your credit cards can quickly be erased by high interest rates.

This tip applies to cards with a 0% introductory annual percentage rates (APRs), as well. If you open one of these cards before making a large purchase, or to use as a balance transfer card, make sure to pay it off within the introductory period or you’ll be billed interest on your remaining balance.
