Understanding Loan Amortization and Interest

In standard fixed-rate mortgages and personal installment loans, each monthly payment is split between principal reduction and accrued interest. In the early years of a 30-year mortgage, the majority of your payment goes towards interest; as the principal declines, the interest portion shrinks and the principal portion increases.

Standard Amortization Formula: M = P [ r(1 + r)^n ] / [ (1 + r)^n - 1 ]
