Are you planning to buy a home and consider an adjustable-rate mortgage (ARM)? An ARM mortgage calculator can help you determine your monthly mortgage payment and how it may change over time. In this article, we’ll cover everything you need to know about ARM mortgages.
What is an ARM Mortgage?
An ARM, or adjustable-rate mortgage, is a type of mortgage where the interest rate can change periodically. The initial interest rate is typically lower than a fixed-rate mortgage, which makes it an attractive option for some homebuyers. However, the interest rate may increase over time, which means that your monthly payment may also increase. This makes it important to understand how an ARM mortgage works and how to calculate your mortgage payment.
Characteristics of ARM Mortgage
The ARM mortgage has several characteristics that distinguish it from a fixed-rate mortgage. Here are some of the key characteristics of an ARM mortgage:
- Adjustable Interest Rate: The interest rate on an ARM mortgage is adjustable and can change periodically over the life of the loan. The initial interest rate is typically lower than a fixed-rate mortgage, which makes it an attractive option for some homebuyers.
- Adjustment Period: The adjustment period is the period of time between interest rate adjustments. It is typically one year, three years, five years, or seven years.
- Index Rate: The index rate is the benchmark interest rate that the adjustable interest rate is based on. Common index rates include the London Interbank Offered Rate (LIBOR) and the Constant Maturity Treasury (CMT) rate.
- Margin: The margin is a fixed percentage that is added to the index rate to determine the adjustable interest rate.
- Negative Amortization: Negative amortization occurs when the monthly payment on an ARM mortgage is not enough to cover the interest due. The unpaid interest is added to the principal balance, which means that the borrower owes more than the original loan amount.
- Conversion Option: Some ARM mortgages have a conversion option that allows the borrower to convert the loan to a fixed-rate mortgage at a predetermined time.
- Cap: The cap is the maximum amount that the interest rate can increase or decrease during an adjustment period. There are two types of caps: periodic caps and lifetime caps.
Understanding these characteristics is essential to understanding how an ARM mortgage works and how to calculate your monthly mortgage payment using an ARM mortgage calculator. By knowing the key features of an ARM mortgage, you can make informed decisions about whether an ARM mortgage is the right choice for your home-buying needs.
Caps are an important aspect of adjustable-rate mortgages (ARMs) that limit the amount by which the interest rate can adjust during a given period or over the life of the loan. Caps protect borrowers from significant increases in their mortgage payments and help them plan their budgets accordingly. There are two types of caps: periodic caps and lifetime caps.
- Periodic Caps limit the amount that the interest rate can adjust during a particular adjustment period. For example, a 2/2/5 cap means that the interest rate can increase or decrease by a maximum of 2% after the first adjustment, by a maximum of 2% after subsequent adjustments, and by a maximum of 5% over the life of the loan. In other words, the interest rate cannot increase or decrease by more than 2% during each adjustment period and more than 5% over the life of the loan.
- Lifetime Caps limit the amount that the interest rate can increase or decrease over the entire life of the loan. For example, a lifetime cap of 5% means that the interest rate cannot increase or decrease by more than 5% over the entire life of the loan, regardless of the number of adjustment periods.
Caps provide borrowers with some degree of certainty regarding the maximum amount they may have to pay each month, even if interest rates rise significantly. However, it’s important to keep in mind that ARM mortgages still carry some degree of risk since interest rates can rise, causing monthly payments to increase.
When considering an ARM mortgage, it’s important to understand the specific terms of the loan and the caps that apply. By doing so, you can make an informed decision about whether an ARM mortgage is right for you and whether the caps provide enough protection against significant increases in your monthly mortgage payments.
