A personal credit score is a numerical representation of an individual's creditworthiness, typically ranging from 300 to 850. It is calculated based on factors such as payment history, credit utilization, length of credit history, types of credit accounts, and recent credit inquiries. Lenders use this score to assess the risk of lending money or extending credit to a borrower. A higher credit score indicates better creditworthiness, making it easier to obtain loans, credit cards, and favorable interest rates. Conversely, a lower score may result in higher interest rates or loan denials. Regularly monitoring your credit report can help maintain or improve your credit score.
