FICO® stands for Fair Isaac & Company and is the name for the most well known credit scoring system, used by Experian. The credit bureau’s computer evaluates a complete credit profile and assigns a score, which is used to estimate credit worthiness. Each of the three bureaus (Experian, Trans Union, Equifax) employs its own scoring system, so a given person will usually have 3 separate scores. Someone with a higher score will be viewed as a better risk than someone with a lower score. Typically, scores will range from about 600 to 700 or above, although some cases will be outside this range.
