A credit score ranges from 300 to 850 and is a numerical rating that measures a person’s likelihood to repay a debt. A higher credit score signals that a borrower is lower risk and more likely to make on-time payments. Credit scores are often used to help determine the likelihood someone will pay what they owe on debts such as loans, mortgages, credit cards, rent and utilities. Lenders may use credit scores to evaluate loan qualification, credit limit and interest rate.
