What Is a Fixed-Rate Mortgage?
In plain English
A fixed-rate mortgage is a home loan where the interest rate remains the same for the entire repayment period — typically 15 or 30 years. Because the rate never changes, your principal and interest payment is constant month to month. Fixed-rate loans are the most popular mortgage type in the United States due to their predictability and simplicity.
How Does a Fixed-Rate Mortgage Compare to an Adjustable-Rate Mortgage?
Fixed-rate mortgages offer payment stability regardless of market conditions. Adjustable-rate mortgages start with a lower rate but can rise or fall after the initial fixed period. Fixed rates typically start higher than ARM teaser rates, but borrowers willingly pay for the certainty, especially when rates are low historically and expected to rise.
Should You Choose a 15-Year or 30-Year Fixed Mortgage?
A 30-year fixed mortgage has lower monthly payments but costs significantly more in total interest. A 15-year fixed mortgage carries a higher monthly payment but a lower rate, and you build equity far faster. If you can comfortably afford the higher payment of a 15-year loan, the long-term savings are substantial — sometimes hundreds of thousands of dollars.
When Is a Fixed-Rate Mortgage the Best Choice?
Fixed-rate mortgages are ideal when interest rates are low and you plan to stay in the home for many years. If rates are high and you expect to sell or refinance within five to seven years, an ARM might save money during that window. For most long-term homeowners, the predictability of a fixed rate outweighs any short-term savings from an adjustable product.
Frequently asked questions
Can you pay off a fixed-rate mortgage early?
Yes. Most fixed-rate mortgages have no prepayment penalty. Extra payments go directly toward principal, reducing interest charges and shortening the loan term — potentially by years.
Does the entire monthly payment stay the same on a fixed-rate mortgage?
The principal and interest portion is fixed. However, your total payment can change if property taxes or homeowners insurance premiums change, since these are collected through escrow and fluctuate annually.

Mortgage
A mortgage is a loan used to purchase real estate, where the property itself serves as collateral. It's typically repaid over 15 or 30 years through monthly payments of principal and interest.
Adjustable-Rate Mortgage (ARM)
An adjustable-rate mortgage starts with a fixed interest rate for an initial period, then adjusts periodically based on a market index. ARMs often have lower starting rates but carry the risk of rising payments.
Refinancing
Refinancing replaces your existing mortgage with a new one, typically to get a lower interest rate or change loan terms. It can reduce monthly payments or help you pay off your home faster.
Private Mortgage Insurance (PMI)
Private mortgage insurance protects the lender — not you — if you default on a conventional loan with less than 20% down. It adds a monthly cost until you build enough equity to cancel it.
Down Payment
A down payment is the upfront cash you pay toward a home purchase, with the mortgage covering the rest. The larger your down payment, the less you borrow and the lower your monthly payments.
