Try keeping credit card balances below 50% of available credit.
Your credit score loves when balance on each of your credit card account is less than 50% of available credit
limit for that account! If you stick with this rule, you will be richly rewarded with higher credit score.
Higher score in turn means better deals on the next credit card, loan or mortgage.
On the other hand, if you got 0% to 6% APR on a new credit card or
balance transfer offer from existing card,
of course fill this account up with balances transferred from higher APR cards! Just make sure to take into consideration
balance transfer fee and don't go over the credit card limit.
