FICO Score

Definition

The family of credit scores built by Fair Isaac Corporation, known as FICO, and used in most U.S. lending decisions.

A FICO Score is calculated only from one bureau's credit report. FICO groups the data into five categories: payment history (35%), amounts owed (30%), length of credit history (15%), new credit (10%) and credit mix (10%). Those weights describe the general population, and FICO says the importance of each varies by person. Base FICO Scores run from 300 to 850.

FICO sells many versions at once. FICO 8 remains widely used for cards and general lending, mortgage lenders still largely use FICO 2, 5 and 4, auto and card lenders often use industry scores on a 250 to 900 scale, and newer versions like FICO 9 and FICO 10T change how specific data counts. Your FICO Score depends on which version a lender buys, and from which bureau.
