How Amortization Works

Amortization is the process of spreading a loan into a series of fixed payments over time. Each payment covers both principal and interest. The formula is: PMT = P × r(1+r)^n / ((1+r)^n − 1), where P is the loan amount, r is the monthly interest rate, and n is the total number of payments. With each payment, the interest portion decreases while the principal portion increases.
