Why might closing credit card accounts negatively impact your credit score?

Closing credit card accounts can negatively impact your credit score primarily because it reduces your total available credit and can increase your credit utilization ratio. When you close an account, the total credit limit across all your accounts decreases. If you have existing balances on your open accounts, this reduction in available credit means a higher percentage of your total credit is being used, which is referred to as credit utilization.

Credit scoring models typically favor lower utilization ratios, as they suggest that you are not overly reliant on credit and that you manage your credit responsibly. A higher utilization ratio can signal to lenders that you may be overextending yourself financially, which can lead to a drop in your credit score.

While the other options touch on relevant aspects of credit management, they do not directly relate to the specific dynamics of credit score calculations in the context of closing accounts. Understanding the impact of credit utilization is key to managing one's credit effectively, and this highlights why maintaining open lines of credit can be beneficial to overall credit health.
