Adjustable Rate Mortgage Calculator


The interest from an adjustable mortgage rate can vary. On the flip side, a fixed rate mortgage stays the same. ARMs usually begin with a low-interest rate while fixed mortgage rates don’t. In addition to, when the introductory period of an ARM end after a certain period of time, the amount of interest you pay and monthly payment increases too.

The index is a broader interest rate measurement that the rate you pay binds to. As the index increases so do your payment. When the interest rate decrease, the amount you pay still increases unless there’s a cap on the interest rate.

An adjustable-rate mortgage calculator is useful to see the effect of interest changes on your mortgage payment, depend on the type of mortgage you chose.

Adjustable Rate Mortgage Types 

Hybrid ARMs

This type of ARM comes with an initial fixed rate cycle. Moreover, the interest rate adjusts on a yearly basis. A cycle in regards to a fixed rate can range anywhere from three to ten years or more.

For example, a Hybrid ARM that’s 3/1 has a fixed rate of three years and moves year to year.

On another note, it’s easy to see that there are many types of ARMs to choose from. Moreover, you might see some of these while shopping.

For instance, at an 8/1 ARM, your fixed rate is 8 years and then adjusts every year.

On the other hand, with a 9/2 ARM, your fixed rate is 9 years and then adjusts every 2 years.

With a 3-year term, you fixed rate is secured for three years and then adjust yearly.

Interest-only ARMs

In a nutshell, this means that you solely pay the interest on a mortgage. You have to agree to pay the interest for a period of time and not the principal. As a result, this gives you smaller payments for that period. The period normally ranges from 5 to 10 years.

For example, you only pay the interest for seven years with a 7/2 ARM with adjustment made every two years.

The loan outlays after the period expires. In addition to, it’s paid off by the length of the term. Also, keep in mind that this has the capability to progress to higher monthly payments.

Payment-option ARM:

This type of ARM allows you to have various payment options such as interest only, a minimum payment, or a 15/30/40-year fully amortizing payment.

Adjustable Rate Mortgage Indexes/Margins 

An index is a process that takes place when an ARM shifts to another interest rate once the fixed rate period stops. A neutral group establishes and index. Moreover, it relies on the market forces. Typically, loan documents define what index follows an ARM. In addition to, there is a lot that goes into this.

One thing to note is that most mortgages rely on one of three of the following indexes:

The London Interbank Offered Rate, the 11th District cost of funds index, or the maturity yield on one-year treasury bills.

The first step is to understand the rate. The lender takes the index rate and adds the margin (percentage points) to determine the ARM rate. While there are many factors that determine your rate, your credit score is the highest determining factor. Moreover, if you don’t know your credit score, there many ways to obtain it for free.

Remember: Margins cannot change – the index rate can.

For instance, you have a 1.75% index with a margin of 2 percentage points. When you add these two together, you get a total of 3.75%. If the index decides to shift to 2% later on, the interest rate will increase to 4%.

Let me repeat: Margins DON’T change. Only the index can change.

Here’s another example: You have an index of 7%, and the margin is 3%. This adds together to a 10% interest rate. The new interest rate is 7% if your index decreases to 4%.
