What Is An Adjustable Rate Mortgage? Are There Any Benefits or Risks Associated With It? Now Let’s Find Out.

Are you tired of paying high monthly mortgage payments and want to save some money? Or are you worried about the uncertainty of the current housing market? Perhaps an adjustable rate mortgage (ARM) could be the solution to your financial concerns. With an ARM, the interest rate can change over time, potentially leading to lower monthly payments and increased affordability. However, there are also risks involved with an ARM, such as the potential for the interest rate to increase and cause financial strain. In this blog post, we’ll explore the ins and outs of an ARM, so you can determine if it’s the right mortgage option for you.

Buying a home is one of the most significant investments you’ll make in your lifetime. With so many different types of mortgages available, it’s important to understand the different options to make the best decision for your financial situation. One type of mortgage that you may have heard of is an adjustable rate mortgage (ARM). In this blog post, we’ll take a closer look at what an ARM is and how it differs from other types of mortgages.

What is an adjustable rate mortgage?

An adjustable rate mortgage (ARM) is a type of mortgage where the interest rate changes periodically based on the current market conditions. Typically, an ARM starts with a lower interest rate than a fixed-rate mortgage, making it an attractive option for borrowers who want to save money on their monthly mortgage payments.

The interest rate on an ARM is usually tied to a specific index, such as the London Interbank Offered Rate (LIBOR) or the Treasury Bill rate. When the index rate changes, so does the interest rate on the ARM. For example, if you have a 5/1 ARM, your interest rate will be fixed for the first five years of the loan, and then it will adjust annually based on the index rate.

How does an adjustable rate mortgage work?

When you take out an ARM, you’ll typically have a fixed interest rate for a certain period, such as 5, 7, or 10 years. After the fixed period ends, the interest rate on the loan will adjust annually based on the current market conditions.

An adjustable rate mortgage (ARM) calculator is a tool that can help you estimate your monthly mortgage payments and total interest costs for an ARM. The calculator takes into account the initial interest rate, adjustment periods, caps, and other relevant factors to provide an estimate of your payments over time.

The adjustment period, or how often the interest rate changes, can vary depending on the loan. Some ARMs have adjustment periods of one year, while others may have adjustment periods of 3 or 5 years.

The interest rate on an ARM is made up of two parts: the index rate and the margin. The index rate is a measure of the current market conditions, while the margin is a fixed percentage rate added to the index rate.

For example, let’s say you have a 5/1 ARM with an index rate of 3{fb1e1880c459e557ac3ce17ffa2de9d6b992aa91487d45f235782beb8d8c21f0} and a margin of 2{fb1e1880c459e557ac3ce17ffa2de9d6b992aa91487d45f235782beb8d8c21f0}. Your initial interest rate would be 5{fb1e1880c459e557ac3ce17ffa2de9d6b992aa91487d45f235782beb8d8c21f0}, calculated as follows:

Index rate + margin = Initial interest rate

3{fb1e1880c459e557ac3ce17ffa2de9d6b992aa91487d45f235782beb8d8c21f0} + 2{fb1e1880c459e557ac3ce17ffa2de9d6b992aa91487d45f235782beb8d8c21f0} = 5{fb1e1880c459e557ac3ce17ffa2de9d6b992aa91487d45f235782beb8d8c21f0}

After the first five years, the index rate changes to 4{fb1e1880c459e557ac3ce17ffa2de9d6b992aa91487d45f235782beb8d8c21f0}. Your new interest rate would be 6{fb1e1880c459e557ac3ce17ffa2de9d6b992aa91487d45f235782beb8d8c21f0}, calculated as follows:

New index rate + margin = New interest rate

4{fb1e1880c459e557ac3ce17ffa2de9d6b992aa91487d45f235782beb8d8c21f0} + 2{fb1e1880c459e557ac3ce17ffa2de9d6b992aa91487d45f235782beb8d8c21f0} = 6{fb1e1880c459e557ac3ce17ffa2de9d6b992aa91487d45f235782beb8d8c21f0}

Once you’ve input this information, the calculator will provide you with an estimate of your monthly payments and total interest costs over the life of the loan. This can help you compare the costs and benefits of an ARM versus a fixed-rate mortgage and make an informed decision about which type of mortgage is right for you.

What are the benefits of an adjustable rate mortgage?

1.Lower initial interest rate:

One of the main benefits of an ARM is the lower initial interest rate compared to a fixed-rate mortgage. This can result in lower monthly mortgage payments, which can help you save money in the short term.


Depending on the loan terms, an ARM can offer more flexibility than a fixed-rate mortgage. For example, some ARMs may have lower caps on interest rate increases, which can help protect you from sudden and significant increases in monthly payments. Additionally, some ARMs may allow for interest-only payments or payment caps, which can further increase your flexibility.

3.Potential savings:     

If you plan to sell or refinance your home before the end of the fixed-rate period, an ARM may allow you to take advantage of lower interest rates and potentially save money on your mortgage.

What are the risks of an adjustable rate mortgage?


The biggest risk of an ARM is the uncertainty that comes with it. Since the interest rate and monthly mortgage payments can change over time, it can be difficult to plan your budget and manage your finances. This uncertainty can be particularly stressful for borrowers on a tight budget.

2.Interest rate risk: 

An ARM is tied to the current market conditions, so if the index rate increases, your interest rate and monthly mortgage payments may also increase. This can lead to unexpected expenses and financial strain.

3.Negative amortization: 

Some ARMs may allow for negative amortization, which means that your monthly payments may not cover the interest owed on the loan. This can lead to a higher loan balance and increased monthly payments in the future.

4.Payment shock: 

If the interest rate increases significantly, you may experience “payment shock” – an abrupt and substantial increase in monthly mortgage payments that can cause financial strain.

5.Refinancing costs: 

If you plan to refinance your ARM into a fixed-rate mortgage in the future, you may have to pay fees and closing costs, which can add up and negate any potential savings from the ARM.

Additionally, because the interest rate on an ARM is tied to the current market conditions, it can be difficult to predict how much your mortgage payments will increase when the rate adjusts. This uncertainty can make it challenging to plan your budget and may cause financial stress.

In conclusion, an adjustable rate mortgage (ARM) can be a viable option for borrowers who are looking to save money on their monthly mortgage payments or who plan to sell or refinance their home before the end of the fixed-rate period. However, it’s important to weigh the benefits against the risks and understand that an ARM comes with the potential for the interest rate to increase over time, leading to higher monthly payments and financial strain. Ultimately, it’s crucial to do your research, consult with a mortgage professional, and make an informed decision that aligns with your financial goals and circumstances.
