A bad credit score is a numerical rating generated by major credit reporting bureaus that falls below acceptable lending thresholds, signaling to financial institutions that an applicant carries a history of missed payments, high debt utilization, defaults, or financial distress. Under widely used scoring models like FICO, credit scores ranging from 300 to 579 are generally classified as poor or bad. Consumers possessing bad credit scores face severe hurdles when attempting to secure apartment rentals, utility connections, car loans, mortgages, or credit cards, and when approved, they are subjected to substantially higher interest rates and security deposit requirements.
