638, but I have a two year credit history, an auto loan, and an error in my report. That is also with three cards at over 80% of their balance. Now, all cards are paid off, the error is being corrected, and the auto loan balance is shrinking. My Mustang is going up for sale tommorrow on my Engine Builder's Website for somewhere around 32-35k. Once it is sold, I will pay off the explorer. According to the FICO simulator once my cards update their balance for this month I will be around 720. Once I add my Mortgage who knows. The highest it has ever been was 687 when I was 19.
