Adjustable Rate Mortgage Calculator

Adjustable rate mortgages can provide attractive interest rates, but your payment is not fixed. This calculator helps you to determine what your adjustable mortgage payments may be.

Your starting adjustable monthly payment is MONTHLY_PI.

Your adjustable rate loan of LOAN_AMOUNT for TERM years has a starting payment of MONTHLY_PI. Your interest rate remains fixed at INTEREST_RATE for ADJUSTABLE_RATE_FIXED months, after that time your interest rate is expected to change by ADJUSTABLE_RATE_INCR every ADJUSTABLE_RATE_FEQ months. Your highest monthly payment, in this scenario, would be ADJUSTABLE_RATE_HIGHEST.

Adjustable Rate Mortgage Calculator Definitions

Adjustable rate mortgage (ARM)
This calculator shows a fully amortizing ARM which is the most common type of ARM. The monthly payment is calculated to payoff the entire mortgage balance at the end of the term. The term is typically 30 years. After any fixed interest rate period has passed, the interest rate and payment adjusts at the frequency specified. A Fully Amortizing ARM will also have a maximum rate that it will not exceed. Below is a list of the most common types of Fully Amortizing ARMs.
Common Adjustable Rate Mortgages

10/1 ARMFixed for 120 months, adjusts annually for the remaining term of the loan.
7/1 ARMFixed for 84 months, adjusts annually for the remaining term of the loan.
5/1 ARMFixed for 60 months, adjusts annually for the remaining term of the loan.

Mortgage amount
Original or expected balance for your mortgage.
Starting interest rate
Initial annual interest rate for this mortgage.
Term in years
The number of years over which you will repay this loan. The most common mortgage terms are 15 years and 30 years.
Interest rate cap
This is the highest interest rate allowed by your mortgage. Your actual interest rate will not be adjusted above this rate.
Months before first adjustment
This is the number of months that the interest rate is fixed. After this period, the interest rate will be subject to rate adjustments. If you enter zero in this field, we assume that the rate will begin making adjustments after initial period of time between adjustments has passed. If any number other than zero is entered, the first adjustment will take place at that time, and adjustments will happen at the frequency entered in the "months between adjustments" field.
Expected adjustment
The amount you believe that your mortgage's interest rate will change. This amount will be added to or subtracted from your interest rate.
Months between adjustments
The number of payment periods between potential adjustments to your interest rate. The most common is 12 months, which means your payment could change at most once per year.
Starting monthly payment
Monthly principal and interest payment (PI) based on your beginning balance and starting interest rate.
Total payments
Total of all monthly payments over the full term of the mortgage. This total payment amount assumes that there are no prepayments of principal.
Total interest
Total of all interest paid over the full term of the mortgage. This total interest amount assumes that there are no prepayments of principal.
