Monthly Payment by Mortgage Type

Definitions

Fixed Rate Mortgage

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.

Interest Only Mortgage

An Interest Only mortgage only requires monthly interest payments. Since you are not paying any principal, this can lower your monthly payment. However, since your mortgage's principal balance is not decreased, you will have a balloon payment at the end of the mortgage's term. Some Interest Only mortgages will also be adjustable rate mortgages (ARM). An Interest Only ARM will often have a period where the interest rate is fixed, and then it is adjusted annually. This calculator assumes that the interest rate for your Interest Only Mortgage remains fixed for the entire term.
