How the Treasury Index ARM Calculator Works

The Treasury Index ARM Calculator estimates your adjusted mortgage interest rate using the current Treasury Index and your loan's fixed margin.

Enter the following information:

• Original loan amount
• Initial interest rate
• Current Treasury Index
• Loan margin
• Adjustment frequency
• Remaining loan term
• Initial adjustment cap
• Periodic adjustment cap
• Lifetime rate cap

The calculator estimates:

• Fully indexed interest rate

• Estimated monthly mortgage payment
• Potential payment increase after adjustment

This estimate helps borrowers prepare for future rate changes throughout the life of the loan.

What the Calculator Includes

Treasury Index

The Treasury Index is the benchmark used to determine future ARM interest rate adjustments for loans tied to Treasury securities. Changes in the index may increase or decrease your adjustable mortgage rate.

Loan Margin

The margin is a fixed percentage established when the loan is originated. It remains the same throughout the loan term and is added to the current Treasury Index.

Fully Indexed Rate

The fully indexed rate is determined by adding the Treasury Index to the loan margin, subject to the loan's rate cap provisions.

Interest Rate Caps

Most Treasury indexed ARMs include initial, periodic, and lifetime caps that limit how much the interest rate can change at each adjustment and over the life of the mortgage.

Frequently Asked Questions

What is a Treasury Index ARM?
A Treasury Index ARM is an adjustable rate mortgage that uses a U.S. Treasury based index, together with a fixed margin, to determine future interest rate adjustments.

How is the new interest rate calculated?
The adjusted interest rate is generally calculated by adding the current Treasury Index to the loan's fixed margin, subject to the loan's interest rate caps.

Does the loan margin ever change?
No. The loan margin is established when the mortgage is originated and remains fixed for the life of the loan.

Can my interest rate increase every adjustment period?
It may, depending on changes in the Treasury Index. However, initial, periodic, and lifetime rate caps limit how much the rate can change.

Are the calculator results guaranteed?
No. The calculator provides estimates based on the information entered. Your actual interest rate and monthly payment will depend on your loan agreement, current Treasury Index values, applicable rate caps, and lender calculations.
