What is the main purpose of amortization in a loan?

Amortization primarily serves to ensure that a borrower fully repays the loan within a specified term. This process involves spreading out the loan repayments into equal installments over time, which typically includes both principal and interest components. As the borrower makes these payments, the amount of principal repaid increases while the interest portion decreases. This systematic approach helps to provide clarity about the payment timeline and assures both the lender and borrower that the debt will be completely settled by the end of the loan term. Understanding amortization is crucial for borrowers, as it affects their monthly budgeting and financial planning, ultimately leading to full repayment of the loan balance.
