How does cancelling a credit card affect your credit rating?

I have a credit card I hardly ever use because of the high interest rate. I do not owe anything on it and I have another card in good standing. If I cancel the high interest card, would that impact my credit rating, positively or negatively?|||Negatively. A Portion of your credit score is based on your total balances divided by total credit limit. For example, if Card A had a 1000 limit and Card B had a 2000 limit, and Card A had a 0 balance and Card B had a 1000 balance. Your credit utilization ratio would be 1000 (balance) / 3000 (credit limit) which is 33%. If you canceled card A, then your credit ratio would be 1000 (Balance) / 2000 (Credit limit) which would be 50%. Furthermore, another factor in your credit score is your oldest line of credit. It is never recommended to close your oldest credit card. Just keep a 0 balance on the card and keep it. Unless, there is a ridiculous annual fee to keep the card.|||Nothing. Bad credit affects ratings. No credit is no rating.
