Answer: -No. In fact, credit card companies that have better incentives and low to no interest are looking for applicants that can maintain in good standings when trusted with high credit limits. I recently applied for a credit card that required I already be in good standings with another credit card company having a minimum $10,000 credit limit on my card. However, I also keep one card with the lowest minimum ($300) for my riskier purchases (online transactions and such) so that if the number gets stolen the thief won't get more than $300 in goods and I will be alerted sooner. -No a high limit doesn't hurt you. The ratio of debt to available credit is the main thing to worry about there. You are doing great in that area. The fact that you have had it for several years and have been paying it on time (right?) will also boost your credit rating. -In my experience I would say that is doubtful, however, when I think about it I have about 5 credit cards and none of them have over a $10,000 limit.Maybe another poster will prove me a liar? -Normally it isn't the LIMIT that puts you at rish for a lower credit score; it is how MUCH of your limit you actually use and keep a balance on.i.e. if you have a $5,000 limit and you are pretty much always over a $4,000 limit without ever really paying it off, that might lower your score.There are a lot of factors that go into your credit score, the number of credit cards you have, what percentage of credit you are actually using (keeping a balance on), late payments, loans, collections accounts, etc.
