What does my credit score actually affect in life?

Your credit score affects more than most people realize. Most obviously, it determines whether you get approved for loans, credit cards, and mortgages, and what interest rate you pay. A poor score can cost you tens of thousands of dollars extra over the life of a mortgage compared to a good score. Beyond borrowing, landlords routinely check credit before renting to you. Many employers, especially for financial or government roles, pull credit reports during background checks. Insurance companies in most states use credit-based scores to set your auto and home insurance premiums. Utility companies may require large deposits if your score is low. Essentially, your credit score functions as a general measure of financial trustworthiness that shows up in many everyday situations.
