Guide to the The Best ARM Calculators (How to Find Top 5, 7, 10 Yr Adjustable Rate Mortgage Calculators


Mortgage calculators are one of the handiest tools to use if you are trying to figure out what type of loan or rate is the right one for you.

Prospective homeowners sometimes struggle between a fixed or adjustable rate mortgage. But this is where an adjustable rate mortgage calculator is helpful.

An adjustable rate mortgage calculator (ARM) can help you compare the amount of interest you will pay over the life of your loan to a loan with a fixed interest rate. Most ARM calculators can be used for different loan terms, like a 5-year ARM calculator, a 7-year ARM calculator, or a 10-year ARM calculator.

An adjustable rate mortgage is excellent for those who might consider moving in a few years or who have less to spend monthly now but could have more later. This is because the adjustable rate is typically lower than a fixed rate.

A 5-year ARM mortgage calculator will show you how much your interest rate will affect your loan after five years, whereas a 10-year ARM mortgage calculator will show its effects after 10 years of an adjustable rate.

The terms 5/1, 7/1, and 10/1, in relation to an adjustable rate mortgage, refer to the number of years of an adjustable rate and how often the rate will change after that.

If you are considering a 7/1 adjustable rate mortgage, therefore, you should consider using a 7-year ARM mortgage calculator to see the impact of your interest rate in the first 7 years and each year after.

This article will point out some of the main differences between an adjustable rate mortgage and fixed rate mortgage so you can understand your results when you use an ARM calculator.

Our guide will also explain why using a mortgage calculator for ARMs is important in understanding your interest rate over the life of your loan. 

Finally, we will highlight a few of the online calculators that can be used as 5-year ARM calculators, 7-year ARM calculators, or 10-year ARM calculators based on certain criteria you may be looking for.

Adjustable vs Fixed-Rate

Before searching for a 10-year ARM mortgage calculator, you should know the key differences between an adjustable and fixed-rate mortgage.

Some adjustable rate mortgage calculators actually compare the adjustable rate to a fixed rate mortgage, but the results can be confusing if you do not understand how the two rates differ.

Adjustable rate mortgages come with different terms. Usually, they are 3, 5, 7, or 10 years. For this time period, say five years, your interest rate will be a low introductory fixed rate.

After the five years, your rate will adjust to a higher amount, usually once per year. A mortgage calculator that is 5-year ARM specific will show you how much interest you will have during the fixed period and then for the remainder of the loan.

A fixed rate, on the other hand, remains the same through the life of your loan. Although this keeps your monthly payments more steady over time, as you can see if you compared the rate using an ARM calculator, your rate can be much higher than an adjustable rate mortgage during its initial period.

The downside of adjustable rate mortgages is that your monthly payments can become unpredictable in the future. A 5-year ARM mortgage calculator may show an affordable rate for you for your initial period, but make sure you look at how your rate increases after the five-year period as well.



Why Should You Use a Mortgage Calculator for ARMs?

The best way to see the difference over the life of a loan is to use an ARM calculator that compares specific fixed rate loan terms to specific ARM loan terms, like a 7-year ARM mortgage calculator.   

If you are considering a house that may be out of your price range now, but you are expecting a salary increase in the future, you might want to consider a 10-year ARM mortgage calculator to determine if you will be able to afford your mortgage payments after the initial period of a lower fixed rate.

Although most mortgage calculators are extremely helpful in determining what loan options and terms you can afford, a mortgage ARM calculator is especially beneficial because figuring out your interest with an ARM can be tricky, since your interest rate changes through the life of your loan.

Your adjustable rate mortgage might also offer a payment cap, which limits how much your interest rate can increase over the course of your loan. A mortgage ARM calculator with a rate cap feature can more accurately help you determine your monthly payment and the interest you will pay.

What to Look for in a Mortgage ARM Calculator

Although ARM calculators are not specifically labeled as 5-year ARM calculators or 7-year ARM mortgage calculators, some do provide special features that can help you determine costs regardless of the initial fixed-rate period of your ARM.

Most adjustable rate mortgage calculators are very different, but there are a few key features you should make sure your ARM calculator has before you begin to use it:

  • Amount of loan
  • Loan term
  • Amortization frequency
  • Initial interest rate
  • Initial fixed-rate period length

This is the pertinent information you will need if you want the most accurate information specific to your loan from an adjustable rate mortgage calculator.

Also, take note that not all adjustable rate mortgage calculators take into consideration every ARM initial period length. Some only provide options for a few ARMs, like a 3- or 5-year ARM mortgage calculator. Make sure the ARM calculator you choose covers the type of ARM you are interested in.
