940 Year Fixed Rate Mortgage Amortization - MyHomeLoanTools.com

40 Year Fixed Rate Mortgage Amortization Example

The 40 year fixed rate mortgage offers monthly payments that are predictable since the interest rate stays the same over the life of loan and lower since they are amortized over 40 years.

In this example, we compare the amortization schedules for a $300,000 40 year fixed mortgage at a 4% annual interest rate to a 30 year fixed mortgage at 3.5%. After reviewing this example, enter your desired mortgage amount and term into the mortgage amortization calculator to see how the principal and interest change over time and help you decide which mortgage best meets your needs.

Amortization Calculator
This 40 year fixed has a monthly payment that is approximately $93 lower than the 30 year fixed. However, the 40 year fixed would require you to pay approximately $116,861 more in total interest over the life of the loan. If you keep the mortgage for 15 years before refinancing or selling the home, you would pay approximately $32,296 more in total interest for the 40 year fixed. As you can see, the length of time you plan to keep your mortgage can have a real impact on which type of mortgage will be most appropriate for you.

Note how little the principal balance changes in the early months of the mortgage and how much of it changes in the final years of the mortgage. This is why extra payments made early on can result in great savings.

Amortization Schedule
The amortization schedule show you how monthly principal and interest payment and principal balances change over the life of your loan.
Interest
The portion of your mortgage payment that is due to the interest rate being applied to the principal balance. The Total Interest for a mortgage is the sum of all interest paid over the life of a loan.
Interest Rate
The percentage of the principal balance of your mortgage that determines how much interest you must pay. The interest rate on your mortgage may change or remain the same depending on the type of loan you have.
Loan Amount
The initial principal balance or your mortgage at closing.
Principal
The portion of your mortgage payment that is used to pay down the current balance of your mortgage. The principal balance represents how much you owe on the mortgage.
Term
The amortization term is one of the key factors that determine your required mortgage payment. Your required mortgage payment for fully amortizing mortgages is the amount that would result in the mortgage being closest to being paid off by the end of the amortization term. Longer amortization terms result in lower required mortgage payments for fully amortizating mortgages, all other things being equal.
