Among the many things that impact your credit score, two important ones are:
1) Do you always pay at least the minimum payment, on time.
2) What is the ratio of credit card debt to available credit.
Whether you pay in full, or make a minimum payment, you are building a good standing with regard to item 1. But carrying a balance doesn't "help" your credit score, because it actually hurts you with regard to item 2.
Now, if you're really considering paying these off monthly, vs. letting it ride, you're probably not talking about thousands of dollars, which means that it may not impact that ratio very much. So the amount of "damage" that you do might be very very marginal. But the idea that carrying a balance helps is wrong.
Interestingly, if you can keep the 0% thing going forever (highly doubtful), then you could theoretically invest that money in some other asset (CD, Home that is appreciating) and gain money on the investment while not losing money on the CC debt. But again, if we're talking about a value that you could (if you wanted) pay every month, we're probably only talking about very marginal gains on any kind of investing.
Just a thought.
Thanks. This is what I wanted to know.
