When you start looking for a home loan, one of the first choices you’ll hear about is the fixed-rate mortgage. It’s the most common loan in the U.S., and that’s because it’s simple and steady.

With a fixed-rate mortgage, your interest rate never changes. That means your monthly payment stays the same for the whole loan. This makes it much easier to budget and plan for the future.

In this article, we’ll explain what a fixed-rate mortgage is, how it works, and why it’s a popular choice for many buyers.

What Is a Fixed-Rate Mortgage?

A fixed-rate mortgage is a loan where the interest rate stays the same from the day you sign until the day it’s paid off. Your monthly payment for principal (the amount you borrowed) and interest (the cost of borrowing) stays steady, no matter what happens with the economy.

Example: If you borrow $250,000 at a 6% fixed rate for 30 years, your monthly payment for principal and interest will always be about $1,499—every year until the loan is finished.

Pros and Cons of a Fixed-Rate Mortgage

Pros	Cons
Stable Payments: Your monthly payment for principal and interest never changes.	Higher Starting Rate: Usually begins with a higher rate than adjustable-rate mortgages (ARMs).
Easy to Budget: Simple to plan for the long run because you always know the amount.	Not Flexible: If interest rates drop, you’re stuck with your old rate unless you refinance.
Protection from Higher Rates: If interest rates in the market go up, your rate stays the same.	Bigger Payments at First: Monthly payments may be higher than with an ARM.
Simple to Understand: That’s why many first-time buyers choose this loan.

15-Year vs. 30-Year Fixed Loans

15-Year Fixed: Higher monthly payments, but you finish paying off the loan faster and save money on interest.
30-Year Fixed: Lower monthly payments, but you pay more total interest over the life of the loan.

Example:

$250,000 loan at 6% for 15 years = about $2,110/month.
$250,000 loan at 6% for 30 years = about $1,499/month.
