15-year fixed mortgage
Definition
A 15-year fixed mortgage is a fixed-rate home loan whose stated term is 15 years. The interest rate stays the same; the term is shorter than a 30-year fixed mortgage.
In plain English
Some fixed-rate mortgages last for different lengths of time. A 15-year fixed mortgage uses one interest rate for the whole loan and is scheduled to be repaid in 15 years. It is a term length, not a different kind of interest-rate product. A 30-year fixed mortgage is the more common longer term. This page does not say which term costs less or is better for a household.
Technical definition
CFPB describes a fixed-rate mortgage as one whose interest rate does not change and treats mortgage term as how long the borrower has to repay. Fifteen years is one common term named on that page.
Why it matters
Readers comparing fixed-rate products need to separate the rate idea from the repayment length.
Example
Jordan takes a fixed-rate loan scheduled to be paid off in 15 years. The rate in the note does not change. A neighbor’s fixed-rate loan scheduled for 30 years is a different term, not a different rate type.

Important note
A 15-year term is not an adjustable-rate mortgage and is not a balloon merely because it is shorter than 30 years.
