Definition: Your FICO score (pronounced FY-koh) is a branded version of your credit score developed by and named after FICO (formerly known as Fair Isaac). According to FICO, the FICO score is score most widely used by the nation's largest banks to make credit and loan approval decisions for applicants.
FICO scores range from 300-850 and are calculated based on information in all three major credit bureaus' individual reports. Therefore, you have three FICO scores, one for each of the three credit bureaus.
Your FICO score is based on five key pieces of information: the timeliness of your bill payments, your level of debt, the types of accounts you have, the length of time you've had credit, and the number of recent credit applications.
You can check your Equifax and TransUnion FICO scores by visiting myFICO.com. Unfortunately, you cannot purchase your FICO score based on Experian credit report data.
FICO is also the name of the company formerly known as Fair Isaac who developed the FICO scoring model.
