A lot has been written in the past few years about the importance of both credit reports and credit scores. The credit report is a listing of all significant financial transactions by a consumer and whether or not those transactions were completed on time and as agreed. The score is a distillation of everything contained on the credit report, boiled down to a three-digit number. That number is supposed to indicate to a creditor or a lender, at a glance, whether or not the consumer in question is worthy of another loan.

Until recently, the three major credit bureaus, Experian, Trans Union and Equifax, all used different but similar systems to devise the credit score, which ranged from 300 at the low end to 850 at the high end. The different systems meant that a consumer checking his or her score with each of the credit bureaus would receive three different credit scores. This led to some confusion as to which score was the "correct" one. The bureaus have recently attempted to solve that problem by creating VantageScore, a unified scoring system that all three bureaus will use. This should result in a consumer receiving the same score no matter which bureau provides it.

But this hasn't entirely stopped the confusion over credit scoring. Unlike the old systems 300-850 range, the VantageScore uses a different scale that ranges from 501-990. In addition to the numeric score, the VantageScore system will also provide a letter grade, ranging from A-F, as follows:

901-990 - A
801-900 - B
701-800 - C
601-700 - D
501-600
