This rating system is meant to develop a snapshot of the risk you currently represent to a lender. Several parameters in your credit file, including the length of credit history, number of open accounts, loans, mortgages, public records, and others are formulated to produce a three-digit score between about 300 and 950. There are other scores used by lenders and insurance companies (some of which are developed by FICO®) such as Application and Behavior scores. These other scores take other information into account.
