Understanding Loan Amortization

Amortization is the process of paying off a debt with a fixed repayment schedule in regular installments over time. Each payment consists of both principal (the loan amount) and interest.

The Importance of the Term

The **loan term** (years) is critical:

• Shorter Term: Higher monthly payments, but you pay **significantly less** total interest.
• Longer Term: Lower monthly payments, but you pay **significantly more** total interest over the life of the loan.

Always try to find the shortest term you can comfortably afford to maximize your savings.

Interest vs. Principal

In the early years of an amortizing loan (like a mortgage), the majority of your monthly payment goes toward **interest**. As the loan matures, a larger portion of your payment begins to pay down the **principal**.

This is why making extra principal payments early in the loan term is highly effective—it reduces the principal balance faster, thus reducing the total interest calculated over the remaining term.
