DEFINITION of 'Credit Score'. A statistically derived numeric expression of a person's creditworthiness that is used by lenders to access the likelihood that a person will repay his or her debts. A credit score is based on, among other things, a person's past credit history. It is a number between 300 and 850 - the higher the number, the more creditworthy the person is deemed to be. Next Up.
