Luckily, avoiding those mistakes is easier than you may think.Here are four common pitfalls, and how you can avoid them.1. Carrying a balance and paying only the minimumOne of the most expensive mistakes you can make with your credit card is carrying a balance from month to month. While paying the minimum keeps your account in good standing, it also allows interest to pile up.Credit card interest rates often exceed 20%, meaning a small balance can quickly grow into a much larger debt.For example, if you owe $3,000 on a card with a 22% APR and assume a minimum payment of $90 per month (3% of your starting balance), it would take you 52 months to pay off your balance in full, and you’d pay an extra $1,678 in interest over that time.Pay off your balance in full each month. If that’s not possible, pay as much as you can and stop using your credit card until you can pay it off.2. Missing payments or making late paymentsLife gets busy, and it’s easy to forget a due date. However, missing a credit card payment can have big, expensive consequences.If you miss a credit card payment — even by just one day — you’ll almost certainly incur a late fee from your card issuer. However, creditors generally wait up to 30 days before reporting any missed payments to the credit bureaus. That means there’s no immediate effect on your credit score.Set up automatic payments or calendar reminders to ensure you never miss a due date. Even making the minimum payment on time can help protect your credit.Want to start earning cash back to apply as statement credits or points toward your next free vacation?

Ignoring your credit utilization ratioYour credit utilization ratio — your total outstanding debts divided by your total available credit — is a big factor in your credit score. Many people don’t realize that maxing out their cards, or even using more than 30% of their available credit, can hurt their creditworthiness.A high utilization ratio can lower your credit score, making it harder to get approved for loans, mortgages, or even some credit cards. Keep your credit utilization below 30%. If possible, pay off your balances early, before your statement closes, to make sure a lower balance gets reported to credit bureaus.4. Applying for too many cards at onceCredit card welcome bonuses are routinely worth hundreds in cash back or travel points. But applying for multiple cards in a short period can do more harm than good.Each credit card application results in a hard inquiry on your credit report, which can temporarily lower your score. Additionally, opening too many accounts too quickly can make lenders view you as a higher-risk borrower.Be selective when applying for new credit cards.

Credit cards can earn you free flights and cash back, but small mistakes can quickly turn into major financial headaches. Luckily, avoiding those mistakes is easier than you may think.

Here are four common pitfalls, and how you can avoid them.

1. Carrying a balance and paying only the minimum

One of the most expensive mistakes you can make with your credit card is carrying a balance from month to month. While paying the minimum keeps your account in good standing, it also allows interest to pile up.

Credit card interest rates often exceed 20%, meaning a small balance can quickly grow into a much larger debt.

For example, if you owe $3,000 on a card with a 22% APR and assume a minimum payment of $90 per month (3% of your starting balance), it would take you 52 months to pay off your balance in full, and you’d pay an extra $1,678 in interest over that time.

Pay off your balance in full each month. If that’s not possible, pay as much as you can and stop using your credit card until you can pay it off.

2. Missing payments or making late payments

Life gets busy, and it’s easy to forget a due date. However, missing a credit card payment can have big, expensive consequences.

If you miss a credit card payment — even by just one day — you’ll almost certainly incur a late fee from your card issuer. However, creditors generally wait up to 30 days before reporting any missed payments to the credit bureaus. That means there’s no immediate effect on your credit score.

A high utilization ratio can lower your credit score, making it harder to get approved for loans, mortgages, or even some credit cards. Keep your credit utilization below 30%. If possible, pay off your balances early, before your statement closes, to make sure a lower balance gets reported to credit bureaus.

4. Applying for too many cards at once

Credit card welcome bonuses are routinely worth hundreds in cash back or travel points. But applying for multiple cards in a short period can do more harm than good.

Each credit card application results in a hard inquiry on your credit report, which can temporarily lower your score. Additionally, opening too many accounts too quickly can make lenders view you as a higher-risk borrower.

Be selective when applying for new credit cards. Only apply for cards that truly fit your spending habits and financial goals.

How to take control of your credit card habits

You are in control of your own credit destiny. Consider the following tips to make sure your credit card is working for you — not against you.

• Check your credit score regularly to understand how your habits affect your financial health.
• Consider a balance transfer card if you’re struggling with high-interest debt — it could help you pay off your balance faster while paying less in interest.
• Look for credit cards with perks that align with your lifestyle, such as cash back on groceries or travel rewards.

Credit cards don’t have to be a source of stress. By using them responsibly, you can build credit and earn rewards.
