What is a score given to an individual based on their likelihood of repaying debt called?

The score that reflects an individual's likelihood of repaying debt is best known as a credit score. A credit score is a numerical representation based on an individual's credit history, considering various factors such as payment history, credit utilization, the length of credit history, types of credit accounts, and recent credit inquiries. This score is used by lenders to assess creditworthiness and determine whether to grant loans or credit and at what interest rate.

While a credit rating may also pertain to an assessment of creditworthiness, it typically refers to institutions or governments rather than individuals. The debt ratio measures an individual's or entity's total debt relative to their income or assets but does not specifically evaluate the likelihood of repaying that debt. The financial index is a broader term that could refer to various metrics related to financial performance but does not directly correlate with an individual's creditworthiness. Thus, the credit score specifically addresses the likelihood of an individual repaying their debt, making it the most accurate term for this situation.
