Monthly Payment by Mortgage Type |
This is a special mortgage program designed to give you a very low payment. This mortgage can result in your principal balance increasing when the monthly payment doesn't cover all of the accrued interest.
A fixed rate mortgage has the same interest rate and monthly payment throughout the term of the mortgage. The payment is calculated to payoff the mortgage balance at the end of the term. The most common terms are 15 years and 30 years.
This 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.
| ARM Type | Months Fixed |
|---|---|
| 10/1 ARM | Fixed for 120 months, adjusts annually for the remaining term of the loan. |
| 7/1 ARM | Fixed for 84 months, adjusts annually for the remaining term of the loan. |
| 5/1 ARM | Fixed for 60 months, adjusts annually for the remaining term of the loan. |
| 3/1 ARM | Fixed for 36 months, adjusts annually for the remaining term of the loan. |
An Interest Only ARM only requires monthly interest payments. Since you are not paying any principal, as you are with the other two types of mortgages described above, this can lower your monthly payment. However, since your mortgage's principal balance is not decreased, you will either have a balloon payment at the end of the mortgage's term or at some point the mortgage will convert to a Fully Amortizing ARM. Like a Fully Amortizing ARM, an Interest Only ARM will often have a period where the interest rate is fixed, and then it is adjusted annually. An Interest Only ARM will also have a maximum interest rate that it will not exceed. This calculator uses a maximum interest rate of 12%.
This is the interest rate used to accrue interest on the Option ARM after the initial fixed period has ended.
This is the maximum amount the Option ARM's monthly payment can increase each year through year five, regardless of the Fully Indexed Rate (FIR).
