Credit utilization question

[hautemama]

Hello, I am trying to rebuild my credit and wanted to know what the ideal is?  I've heard some say 35%, 30% or 25%.  Which is it?? And is it better to use card and PIF each month, or keep a balance?  Any input is greatly appreciated.

you want your utilization to be between 7-9 percent. Pay all but one of your cards in full and leave one with a small balance.
