What are the pros and cons of having a high credit limit?
I was recently approved for $7k credit limit with RBC Royal Bank (Canada) and $19.5k credit limit with RBC Bank (US), both credit cards. In addition I have two other credit cards with limits $500 and $2000. So in total around $30k. It's probably not very high compared to mortgages, car loans and etc, but I have no mortgages or any other forms of credit. I know I won't be using anywhere near the limit, so to me this is very high. So my question is what are the pros and cons of having such a high credit limit, both pooled and on a single card? Is there any point to keeping it that high or should I call the banks to reduce it? Also, how does this affect my credit score?
