Adjustable Rate Mortgage Calculator

In an Adjustable rate mortgage, the interest rate increases or decreases periodically. This may lead to cheap interest rates or, on the other hand, somewhat high rates. If the low interest rates remain steady, the mortgage on adjustable rate could be inexpensive and low over a long period of time. An adjustable rate mortgage calculator helps us to calculate the monthly payments over the life of the loan. The mortgage on adjustable rate can be tied to many indexes.

Adjustable Rate Mortgage (ARM)

Most homebuyers prefer an ARM because of its low starting interest rate for a specified period when compared to 15- and 30-year mortgages. The payments in ARM vary over a period of time. The low rate of an ARM is because it is may be two to three points below the conventional fixed rate. The adjustable mortgage rates should be considered only if the borrower is financially secure to handle the volatile interest rates. For a specified time period, this cheap rate is used to calculate the monthly payments. Once this initial period is over, the interest rate is adjusted from time to time based on a pre-selected index. The index used is the yield on the one-year treasury bill. The new interest rate is calculated by adding this index to a set margin determined by the lender. Adjustable mortgage programs for 1,3,5,7 and 10 years are available at relatively inexpensive rates. The 1-year adjustable mortgage is most common, although different individuals have different time horizons for the length of the loan. The Annual percent rate on such mortgages may show an increase or decrease per year. If there is an increase in the rate index, there would be an increase in the monthly payments. If the interest rate declines over a long period of time, the mortgage on adjustable rates could turn low. The adjustable-rate mortgages are also known to be assumable as the mortgage could be transferred to the new buyer with the same terms.

Regarding the risk on the interest rate, consider a worst-case scenario where there is a maximum yearly increase of 2% points and a lifetime cap of 6% points on a $100,000 adjustable-rate mortgage. The homebuyer must know if he can afford the highest possible payment in such a situation. An adjustable rate mortgage calculator can help us in calculating the monthly payments to check this out.

Using this calculator, we see that in the first year, the rate is 5.75%, and the monthly payment is $583.57. In the second year, the rate is 7.75%, and the monthly payment is $713.46. In the third year, the rate is 9.75%, and the monthly payment is $850.95. In the fourth year, the rate is 11.75%, and the monthly payment is $993.04, with a 6% lifetime cap. The payment in the fourth year is almost $409.47 more than in the first year.

Adjustable Rate Mortgage Loan

An ARM loan is the best option if the homebuyer plans to live in the home for less than the fixed portion of the loan. The difference between the loan on adjustable-rate mortgage and the fixed rate mortgage could be invested for the future. If the interest rates are high, you can time the loan when the interest rates are lower. These loans have an initial fixed rate period of 1,3,5,7, or 10 years, after which the rates are adjusted on a yearly basis. Most of the adjustable mortgage agreements allow the borrower to pay the loans in full or in part without imposing a penalty. The prepayment details can be negotiated. The borrower could negotiate for a penalty-free loan or a low penalty. There are also many a built in caps to protect a person against a huge payment increase. These could be lifetime cap, periodic rate cap, or payment cap. The lifetime cap restricts the increase in the interest rate during the life of the loan. The periodic rate cap restricts the payment increase for a time period. The payment cap restricts the payment increase during the life of the loan. The rate caps are applicable when the rates fall and rise. The adjustable loans may have complicated terms so the borrowers have to understand the terms before opting for the loans.

Adjustable Mortgage Rates

The Adjustable mortgage rate is tied to a number of indexes. The lender also adds a margin to the index, which is usually around 2% points or 4% points, set to the actual rate. The most common index is the one-year U.S Treasury bill. This is used to set rates on 30 year mortgages. The initial rate is lower than that of the fixed mortgage rate. The common adjustable rates are 1/1, 3/1, 5/1, 7/1 and 10/1. The adjustable mortgage rates are not adjusted every month but every one year or every three years. The six month adjustment rates are said to be difficult to handle. These adjustments should be clearly spelt out in a loan agreement. The adjustable rate mortgage could be converted into a fixed rate mortgage if it is essential. If the ARM were assumable, the buyer would have to qualify to assume the existing mortgage, if the house is sold. This is particularly helpful when the mortgage rates are high.
