What is Loan Amortization?

Amortization is the process of spreading out a loan into a series of fixed payments over time. While the payment amount stays the same each month, the portion of the payment that goes towards principal and interest changes. At the beginning of the loan, a larger part of your payment covers interest. As you continue to make payments, more and more of your payment goes towards reducing the principal loan balance.

The Amortization Formula

The calculation for the monthly payment on an amortizing loan is based on this standard formula:

Where:

• M = Your fixed monthly payment
• P = The principal loan amount
• i = Your monthly interest rate (annual rate divided by 12)
• n = The total number of payments (loan term in years multiplied by 12)

Frequently Asked Questions (FAQ)

How does an amortization schedule help me?

An amortization schedule is incredibly useful for financial planning. It shows you exactly how much equity you are building with each payment and the total amount of interest you will pay. This can help you make informed decisions, such as whether to refinance or make extra payments.

Why is so much of my early payment going to interest?

This is how amortization works. Interest is calculated based on the outstanding loan balance. Since your balance is highest at the beginning of the loan, the interest portion of your payment is also at its highest. As you pay down the principal, the interest due each month decreases, allowing more of your fixed payment to go towards the principal.

How do extra payments work?

When you make an extra payment, that money is typically applied directly to your principal balance. It does not go towards future interest. By reducing the principal, you reduce the amount of interest that accrues in the following months, which allows you to pay off the loan significantly faster and save a substantial amount of money.
