Paying off a loan early can have an impact on your credit score. While it may decrease your average credit history length, which can potentially lower your credit score, practicing good financial habits like making on-time payments and avoiding excessive new credit applications can help improve your score. It is also important to consider other loan management alternatives, such as talking to your lender about adjusting terms or seeking a lower interest rate, opening a balance transfer credit card, or exploring loan management options based on your individual circumstances.
