Understand these free basics now or learn expensive lessons later.

Getting your first credit card is an exciting milestone with significant responsibility, but don’t let your new credit line tempt you to the max.

Your credit choices today will follow you for years and can affect your ability to borrow money for big purchases you might need in the future, like a vehicle or home.

While credit cards can be powerful financial tools when used wisely, they can also lead to costly mistakes that could take years to correct.

Whether you’re a college student getting your first credit card or an adult new to the credit world, these three concepts will help you make informed decisions and use credit to your advantage.

1. You can build your credit history and boost your credit score, or you can damage it and face consequences in the future.

   Your credit history is a detailed record of your past and current credit use, displaying your borrowing and repayment habits.

   Your credit score derives from your credit history and represents your creditworthiness. Credit scores generally range between 300 and 850, with 300 being poor and 850 being excellent.

   Factors that affect your credit score include your payment history, how much money you owe, the length of your credit history, recent credit checks, and other types of credit you use. A positive, stable credit history with consistent, timely payments and low credit use will usually result in a higher credit score.

   While there are several strategies you can use to help boost your credit score and avoid damaging your credit, here are a couple of the most important things to keep in mind:

   • Always pay on time. Setting up autopayments or scheduling time to make manual payments before the due date can help. If you miss a payment, you will be charged a late fee, and your credit score could suffer.
   • The amount of credit you use compared to your credit limit matters. Your credit utilization ratio is the percentage of available credit you use. The lower it is, the better. Experts recommend staying below 30%. For a card with a $5,000 credit limit, the balance would need to be below $1,500 to stay under 30% utilization.
2. You can make minimum payments instead of paying your monthly balance in full, but more money will come out of your pocket. To build responsible credit habits and avoid debt, don’t use credit as “free money” to buy things you can’t afford.

   Interest is what you pay for borrowing money and is added to the amount borrowed. Interest is usually described as an annual percentage rate (APR) for credit cards.

   The APR represents the total cost of borrowing for a year, including interest and any other fees. It’s always wise to compare costs when choosing a credit card; APR helps you do this.

   Keeping a credit card balance will cost you extra, according to the annual percentage rate (APR). In August 2025, the average APR was 23.99%, so if you had a credit card with this APR and held a $1,000 balance for a year, you’d owe an additional $271 in interest if the interest compounds daily. You can avoid accruing interest by paying your balance in full every month.

3. These fees can add up, but you may be able to avoid them:

• Annual fee: Some cards charge annual fees, which might be worth it if rewards and perks come with the card. However, there are credit cards without this fee.
• Late fee: If you don’t pay by the due date, you’ll be charged a late fee. You can avoid this by signing up for autopayments or scheduling time for manual payments before the due date.
• Foreign transaction fee: This fee, usually 3% of the amount charged, can occur when making purchases outside the U.S. If you plan to use your card during international travel, look for credit card issuers that don't charge this fee.

Start smart, stay smart.

Your habits as a new credit card user will shape your financial future. Paying on time, keeping your balance as low as possible, and reading the fine print on fees will put you on the fast track to a credit score boost that stays positive over time.
