A good credit card balance is one that is $0.00 zero dollars because then it means you owe the credit card company no money and it means you are not in debt.
A low credit card balance like $50.00 is better than a high credit card balance like $4,900.00 because it should take you a very short time to pay back the $50 to the credit card company, but it may take you a very long time to pay back the $4,900 causing you a heap of stress. On top of that, your interest charges by the credit card company will be high every month for such a big balance due. Interest is, after all, how they make money out of you.
One good thing about paying off a high credit card balance is that, if you pay your minimum amounts due every month without fail, it may help your overall credit rating (a credit rating affects your accessibility to future loans or mortgages).
So don't skip any payments!
You should try to pay more than the minimum amount because the minimum amount may barely cover the interest you are charged and then you'll 'never' get out of debt with the credit card company.
