A credit score is a number that helps lenders and others predict how likely you are to make your credit payments on time. Each score is based on information in your credit report.
As a rule, credit scores analyze the credit related information on your credit report. How they do this varies. Since FICO scores are frequently used, here is how these scores assess what is on your credit report.
By law, credit scores may not consider your race, color, religion, national origin, sex and marital status, and whether you receive public assistance or exercise any consumer right under the federal Equal Credit Opportunity Act or the Fair Credit Report Act.
When lenders talk about your score, they usually mean the FICO score developed by Fair Isaac Corporations. FICO scores range from 300-850, and most people score in the 600x and 700s. Higher FICO scores are better.
