Why You Should Never Close Your Oldest Credit Card
Many people think that closing an old credit card is a good way to simplify their finances or avoid temptation, but this can have serious implications for your credit score. By the end of this post, you’ll understand why keeping your oldest credit card open is crucial for your financial health and how to handle your credit cards wisely.
Step 1: Understand Your Credit Score
Before you make any changes to your credit cards, you need to understand what a credit score is and how it affects you. In the U.S., credit scores range from 300 to 850, with 700+ considered good. One of the key components of your credit score is your credit history length, which measures how long your accounts have been open.
Why it matters: Closing your oldest credit card can shorten your credit history, which can lower your score. For instance, if your oldest card is 10 years old and you close it, your average account age could drop significantly, potentially lowering your FICO score.
Common pitfall to avoid: Many people focus solely on their credit utilization ratio (the amount of credit you're using compared to your credit limit) without considering the age of their accounts. Don't make the mistake of prioritizing short-term goals over long-term credit health.
Step 2: Know How Credit Utilization Works
Credit utilization is the percentage of your total available credit that you’re currently using. For example, if you have a total credit limit of $10,000 and a balance of $2,000, your credit utilization is 20%. Financial experts recommend keeping your utilization below 30% for optimal credit health.
Why it matters: If you close your oldest credit card, you’re reducing your total credit limit. This can increase your credit utilization ratio, which can hurt your score. If you had a $5,000 limit on that card and you close it, your total available credit drops to $5,000, boosting your utilization from 20% to 40% if your balance stays the same.
Common pitfall to avoid: Don't assume that closing a card with no balance will not affect your utilization. It still impacts your total credit limit and can lead to a higher utilization ratio, which can negatively affect your score.
Step 3: Consider the Impact on Your Credit Mix
Your credit mix refers to the different types of credit accounts you have, such as credit cards, auto loans, and mortgages. Having a diverse credit mix can positively impact your credit score. If you close your oldest card, you might limit your mix, especially if you don’t have many other revolving credit accounts.
Why it matters: A diverse credit mix can make you appear more responsible to lenders. If your oldest card was a major credit account, it may have been contributing positively to your mix.
Common pitfall to avoid: Don’t overlook the importance of maintaining a healthy mix of credit types. Before closing any account, evaluate how it fits into your overall credit picture.
Step 4: Keep Credit Card Fees in Mind
Some older credit cards come with annual fees, and you might feel tempted to close them to avoid these costs. However, consider whether the benefits outweigh the fees. For instance, if your oldest card offers travel rewards that you frequently use, the fee may be worth it.
Why it matters: Closing a card to save on fees may save you a few dollars now, but it can cost you in terms of credit score down the line.
Common pitfall to avoid: Don’t close a card just because of an annual fee. Instead, weigh the card's benefits against the cost. You might find that the rewards or perks justify keeping it open.
Step 5: Develop a Strategy for Managing Old Cards
If you decide to keep your oldest credit card open, you may need a strategy for managing it effectively. This could involve setting up automatic payments for small purchases or using the card for regular expenses that you would pay off each month.
Why it matters: Keeping the card active by using it regularly can help maintain its status as an open account, thus preserving your credit history and utilization ratio.
Common pitfall to avoid: Don’t let the card sit unused for too long, as inactivity can lead to the card being closed by the issuer. Make sure to use it occasionally to keep it in good standing.
What to Expect After Completing All Steps
By following these steps and keeping your oldest credit card open, you’ll likely see your credit score remain stable or even improve over time. This can lead to better loan terms, lower interest rates, and more opportunities for credit in the future.
Remember, maintaining a healthy credit score isn’t just about paying your bills on time; it’s about understanding how your credit accounts work together. So, think twice before closing that oldest card—it could be the key to your financial future!
