A fixed rate mortgage is a mortgage loan where the interest rate on the note remains the same through the term of the loan. This is different from other mortgages where the interest rate may adjust or "float."

Fixed rate mortgages are characterized by their interest rate (including compounding frequency, amount of loan, and term of the mortgage). With these three values, the calculation of the monthly payment can then be done.

The price of the Fixed Mortgage Rate is calculated by adding Index + Margin = Fully Indexed Rate. This is the interest rate for the life of the loan.

Fixed rate mortgages are the most classis and popular type of home loans in the United States. The most common terms are 15-year and 30-year mortgages, but shorter terms are available, and 40-year and 50-year mortgages are now available.

Fixed rate mortgages are usually more expensive than other types of mortgages. This is because of the inherent interest rate risk. Therefore, long-term fixed rate loans will tend to be at a higher interest rate than short-term loans.
