Adjustable Rate Mortgage Loan
Use this calculator to estimate what your monthly adjustable mortgage payments may be.
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. 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.
Starting interest rate
Initial annual interest rate for this mortgage.
Term in years
The number of years over which you will repay this loan.
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.
The amount you believe that your mortgage's interest rate will change. This amount will be added to or subtracted from your interest rate.
