A FICO score is a particular type of credit score — one offered by FICO, the company that pioneered their use. Like other credit scores, a FICO score is a three- digit numeric value that assesses a borrower’s credit risk. Your FICO score can range from 300 to 850. The higher the number, the more likely the loan is to be repaid. People with low FICO scores get charged higher interest rates to make up for the added risk. People with high FICO scores get the best deals. FICO scores are calculated using complex formulas that predict future debt repayment behavior. Income, credit lines outstanding, debt to income ratio, mix of credit and past payment behavior all factor into a person’s FICO score.
