Explained: ARM vs. Fixed-Rate Mortgage

Are you starting the home buying process? Before you begin the application process for a home mortgage, it is beneficial to understand the difference between an adjustable-rate mortgage (ARM) and a fixed-rate mortgage. Having this knowledge will help you select the right mortgage plan for your home buying needs.

So let us have a quick look at what ARM and fixed-rate mortgage are and their differences.

Adjustable-Rate Mortgage

ARM or adjustable-rate mortgage plan is a type of loan that comes with a variable interest rate. This means the interest rate can fluctuate or change after a pre-determined time period. However, there is a limit to how much a lender can increase the interest rate. The lender will provide you with the details on changing the interest rate in the printed mortgage contract.

An ARM’s interest rate resets after a specific duration, depending on your loan. The adjustment of the interest rate can be seen as a fraction. The first number of the fraction identifies when your rate initially resets. The second number shows how frequently your interest rate will change after the first-rate adjustment.

So, if you have a 5/1 ARM, this means you will enjoy a fixed rate for the first 5 years, and then your rate will adjust every year. An ARM is typically a 30-year mortgage.


  1. Your introductory rates may be lower than a fixed-rate mortgage interest rate.
  2. Future rate adjustments may not affect you, especially if you plan to sell your home before your introductory period expires.


  1. Changes in the market’s interest rate may change your monthly repayments.
  2. ARM only offers a 30-year loan option.
  3. This loan is less stable because of the variable rate change.

Fixed-rate Mortgage

A fixed-rate mortgage is a straightforward home mortgage plan compared to ARM’s variable rate. By securing a fixed-rate mortgage, you will have peace of mind knowing that there will be no interest rate fluctuations or increases in the future.

Another main difference you will find in this type of mortgage plan is the variety of loan terms or amortization schedules. Unlike the ARM, which offers only 30-years loans, you can get a 10-year, 15-year, or 30-year loan with a fixed-rate mortgage.

The shorter loan terms for a fixed-rate mortgage will make the monthly mortgage payments larger, but it will allow you to pay off the loan quicker.


  1. The fixed interest rate will not change even if the market rate changes.
  2. More stable with predictable interest rate and mortgage payment.
  3. You can get a 10-year, 15-year, and 30-year loan.


  1. You may have to pay an interest rate higher than ARM’s introductory interest rates.
  2. In the case that the market interest rate decreases, you will need to refinance and pay associated costs to take advantage of current lower interest rates.
