<prompt> Human: I hope this is okay since I didnt find an answer in the community info. Ive just been approved for my first credit card. It has a low line of 500 and I planned on using it for gas and then paying it off at the end of the month. However, Ive been recently told that I have to carry a balance from month to month to actually build up credit. In my own research on this Ive found about half of sites support this and the other half dont. So is this carry over balance true or not? And if so can anyone explain how doing this aids in building your credit score. Thanks so much.  <response>: Even if it helped your credit score, it would be a very expensive way to do so as credit card interest is not cheap and it compounds monthly. That said, it does not at all help your credit score. Pay it in full every month.
