Should You Break Up With Your Credit Card?

NEW YORK (LowCards.com) -- Credit cards are like relationships. It's sometimes hard to break up, and the split may hurt you more than the other party. While it may feel good to cut up that credit card, losing the available credit could hurt your credit score and raise the costs of future loans.

Closing a credit card account you have paid off or don't use seems like a logical thing to do. But the "credit utilization ratio" is one of the major factors in calculating your credit score, accounting for approximately 30% of it, and closing an account can have a dramatic effect on that ratio.

Closing a credit card account you have paid off or don't use seems logical. But watch out for how cutting up that card affects your "credit utilization ratio."

When it comes to your credit cards, the credit utilization is the ratio of all your credit card balances to the credit limits available on your cards. Having a low ratio -- not having much debt but a lot of available credit -- is beneficial to your credit score, while a high ratio may indicate you may be a risk for default. A healthy credit utilization ratio is anything below 30%.

Closing an old or unused card erases some of your available credit and increases your credit utilization ratio. For example, say you have two credit cards -- one with a $3,000 balance and one with no balance, and each card has a $5,000 credit limit. Your credit utilization ratio is 30% ($3,000 divided by $10,000), a very attractive ratio for lenders to see. But if you close the account with no balance, you decrease your available credit by $5,000, so your credit utilization ratio increases to 60% ($3,000 divided by $5,000).
