ARM vs. Fixed Rate Mortgage Calculator

Compare a fixed rate option with an adjustable rate mortgage loan

Is an Adjustable Rate or Fixed Rate Mortgage the Better Option for You?

This calculator helps you get a general estimate. For a more personalized experience for your specific budget, try our Home Insight© Planner.


You’ll enter your purchase price, down payment amount and expected years in the home.

You can also expand the other sections (Fixed Rate Loan, Adjustable Rate Loan, Adjustment Terms and Taxes & Insurance) to edit any additional fields, if you know the amounts.

Based on your information, the calculator will tell you which rate option will save you money, and how much money it’ll save over the number of years you expect to stay in the home.

If your loan is fixed rate, you’re charged the same amount of interest for borrowing the money over the full term of the loan. This allows your monthly payments to stay the same.

If your loan is adjustable rate, the amount of interest you’re charged can change during the loan term. 

Interest rate is based on a combination of market and personal factors – the current economy, your credit score and how you’ll use the property.

Mortgage rates can change daily. Check current mortgage rates.
