5 Credit Card Mistakes to Avoid

We're thrilled to present this smart Kiplinger story here on Savvy!

Whether due to confusion or carelessness, credit card mistakes are all too common. The fallout can be costly, no matter what the cause. Even a single slip-up can result in higher interest rates, lower credit limits, unwanted fees or dings to a credit score.

New rules put in place by the Credit CARD Act of 2009 and the Dodd-Frank Act of 2010 help, as does the formation of the Consumer Financial Protection Bureau, which monitors the credit-card industry. But ultimately it’s up to you to use credit wisely.

Take a look at 5 of the most common credit card mistakes and learn how to avoid making them.

Paying Bills Late

Late payments are the “biggest foul” when it comes to credit cards, warns Ben Woolsey, director of marketing and consumer research at The consequences can include late fees, jacked-up interest rates and a lower credit score.


Take Chase Bank’s Sapphire card, for example, which has a current annual percentage rate of 13.24%. If you make a late payment, the APR could jump to 29.99%. Plus, you’ll be hit with a late fee of up to $35. If you miss two or more consecutive payment dates, the late fee can soar to 3% of the outstanding balance.

Late payments, especially those more than 30 days overdue, can hurt your credit score. Payment history accounts for 35% of a FICO score, the most common credit score, which ranges from 300 to 850. A single 30-days-late payment can drop your score by 60 to 110 points, according to

The lesson: Pay your bills on time, every time. The CARD Act requires banks to mail your statement at least 21 days before the due date. Mark your calendar, and allow enough time for postal delivery. Or better yet, pay bills online.

Bungling Balance Transfers

Moving debt from a high-interest-rate card to one with a low introductory rate can make financial sense--but only if you read the fine print. If you ignore or misunderstand balance-transfer rules, you could end up owing even more.

Start by determining exactly how long the introductory offer lasts. Then ask yourself whether you have the discipline and means to pay off the debt before the APR goes up. Otherwise, you could find yourself eventually paying a higher interest rate.

Next, check whether an introductory offer entails a transfer fee. “Very few cards offer a truly free transfer anymore,” says Woolsey. Fees, which don’t have a cap, currently range between 3% and 5% of the amount transferred.

Even with a fee, a balance transfer can be beneficial. Let’s say you move $5,000 from a credit card charging 14% interest to a card with a 0% APR for 12 months and a 4% fee. The transfer fee would add up to $200. In contrast, paying a fixed rate of $120 a month on your old card would cost you about $650 in interest over those same 12 months.

Making Minimum Payments

Most of us know that we should pay more than the monthly minimum on a credit card bill, but it’s all too easy to put that extra $50 toward dinner or shopping instead. After all, what difference would a few bucks a month make anyway? The answer: a huge difference.

If you have a balance of $5,000 with an APR of 14%, and you only pay the minimum of $100, it will take 22 years to pay off the debt in full, according to a Federal Reserve credit card calculator. You’ll also hand over $6,110 in interest. Boost your monthly payment to $150, however, and you’ll be debt-free in four years and pay $1,369 in interest.

Thanks to the CARD Act, you don’t have to do the math yourself. Your monthly statement now includes information on how long it will take to pay off your balance by only making minimum payments, as well as how much you would need to pay to erase your debt in three years.

Using Up All Available Credit

No matter how many cards you hold, keep an eye on your credit utilization ratio, or the proportion of your total available credit used each month. You may want to apply for another card if you are using up a big chunk of your available credit, even if you aren’t close to maxing out your limits. In general, Kiplinger recommends spending no more than 30% of your revolving credit card limits.

The total amount of your available credit that you access can have a big impact on your credit score. While new credit determines 10% of your FICO score, amounts owed determines 30%.

For example, if you have two cards, each with a $1,000 limit, you have $2,000 in total available credit. That means you can charge $600 between the two cards, while still keeping your credit utilization ratio at 30%. If you spend that same amount but only have one credit card with a $1,000 limit, then you will have used 60% of your available credit.

Be sure to use all of your cards periodically. If a card is inactive for a long period, the lender may close the account. That could result in an unexpected jump in your credit utilization ratio, which could drag down your credit rating.

Ignoring Monthly Statements

This may be the easiest pitfall to avoid. As soon as you receive your monthly credit card statement, take a few minutes to look it over. Mistakes happen, so be sure there are no erroneous charges. The sudden appearance of unfamiliar charges can also signal identity theft. Call your lender immediately to report discrepancies.

Reading your bill can also help you understand how long it will take to pay off your debt. As mentioned earlier, the length of time required to retire your balance by making minimum payments is displayed, as is how much you would need to pay each month in order to pay off your balance in three years. These numbers could act as a wake-up call for you to increase your monthly payments.

Also, pay attention to the various interest rates you pay on purchases, cash advances and such. Look for changes from the previous month. Lenders are now required to give 45 days’ notice before hiking rates. And it never hurts to double-check the due date of your bill to avoid late fees.

Your point on the credit utilization ratio is one of the most under-exposed in the "credit counseling" hype encouraging people to close their accounts if they are not being used! Most people have argued until blue in the face because a Celebrity told them to get away from credit cards...which in and of itself is sound advice, but much to people's detriment more than anything else!
