In the realm of finance, it is crucial to understand the concept of penal interest. This term refers to the additional fees incurred when a borrower fails to make timely installment payments according to the agreed upon repayment plan. Essentially, it serves as a penalty for delayed payments. As a responsible borrower, it is important to honor the repayment terms to avoid incurring penal interest. This not only helps maintain a good credit standing, but also ensures a smoother financial journey.
