I have a credit card with a balance of about $5000 out of $10,000 limit, i.e. about 50%. If I take out a new credit card which has a credit limit of $5000 and pay off the old credit card will it improve my credit score because my balance will be only $5000 against a limit of $15,000. Or will I get dinged because I will be maxed out on my new credit card?
