What Is a 15-Year Fixed Mortgage and How Does It Work?

How Does a 15-Year Fixed Mortgage Work?

When you choose 15-year financing to buy your home, your loan will be structured so you repay the full amount due in 15 years. Your principal and interest payment won’t change during the loan term. This is a key difference between adjustable-rate and fixed-rate mortgages. Here’s a breakdown of some key features of a 15-year fixed-rate mortgage:

• Fixed interest rate: Interest is the cost of borrowing. Since the rate doesn’t change, you’ll know the total and monthly costs up front. Each month, your payment will cover the principal and interest due.
• Lower interest paid over time: A 15-year mortgage usually has a lower rate than a 30-year fixed-rate mortgage. The costs of borrowing will be lower both because of the better rate and because you only pay interest for 15 years instead of 30 years.
• Shorter repayment period and higher monthly payments: Since you’re paying off your loan more quickly, each monthly payment must be much higher to bring the balance to $0 in half the time it takes for a 30-year loan to be repaid.

15- vs. 30-Year Fixed Home Loans

Here’s an example comparing a 15-year fixed-rate mortgage with a 30-year fixed-rate loan. Let’s assume it’s for a $400,000 loan obtained in August, 2026.

The 15-year mortgage has much higher monthly payments. The payments are $756 more per month, but result in total interest savings of $355,137 and have your house paid off 15 years earlier.

Is a 15-Year Fixed Mortgage Right for You?

Whether a 15-year loan is the right type of mortgage for you depends on your current finances as well as your future goals. Weighing the pros and cons can help you find the balance.

15-Year Fixed Home Loan Advantages

Here are some of the biggest potential benefits of a 15-year fixed-rate mortgage:

• Less interest paid: The shorter the period of time you borrow at a given rate, the less total interest you will pay.
• Faster equity growth: Home equity is the value of your home minus the amount you owe the bank. Since a 15-year loan allows you to pay off your mortgage faster, you build equity faster.
• Lower interest rate: Both your mortgage interest rate and annual percentage rate (APR) are typically lower with a 15-year loan, and since it’s paid off faster, you’ll see significant interest savings over the life of the loan.

15-Year Fixed Home Loan Disadvantages

There are also some potential downsides to 15-year mortgages, including:

• Higher monthly mortgage payment: Since you have only 15 years to repay your loan, each monthly payment must be higher to pay off your principal balance on time.
• Less budget flexibility: You’re committing to the larger payments when you take a 15-year loan, which means you’ll have less money to work with after monthly bills.
• Limited home affordability: You can only borrow to buy a home if the lender believes your monthly payments will be affordable based on your debt-to-income ratio (DTI). Since a 15-year mortgage makes your payments higher, you may qualify for a smaller home loan than with a 30-year mortgage in order to stay within your lender’s debt-to-income ratio guides.
• Stricter qualifications: Because the monthly payments will be higher than if you had a 30-year loan, you’ll need a higher income and strong credit profile to qualify.

How to Get a 15-Year Fixed-Rate Home Loan

If you’re interested in a 15-year fixed-rate mortgage, preparing before you apply can help simplify the process. Here are the basic steps involved:

1. Review your credit and finances. Check your credit score, review your budget, and determine how much you can comfortably afford to borrow.
2. Explore your loan options. Depending on your eligibility, you may qualify for a conventional, FHA, VA, or USDA loan.
3. Choose the loan that’s right for you. Compare factors like down payment requirements, eligibility guidelines, mortgage insurance, and loan costs to determine which option fits your needs.
4. Get prequalified. Mortgage prequalification can help you estimate how much you may be able to borrow and understand your financing options.
5. Find a home and apply for your mortgage. Once your offer is accepted, your lender will continue the underwriting process and prepare your loan for closing.
6. Close on your home. Review and sign your loan documents before receiving the keys to your new home.

Can You Refinance from a 30-Year to a 15-Year Home Loan?

If you qualify, you can refinance from a 30-year mortgage to a 15-year mortgage. Refinancing replaces your current loan with a new one, allowing you to pay off your home sooner. While your monthly payment will likely increase, you may qualify for a lower interest rate and pay less interest over the life of the loan.

Refinancing from a 30-year to a 15-year mortgage may make sense if you:

• Can comfortably afford a higher monthly payment.
• Want to pay off your mortgage sooner.
• Want to reduce the total interest you pay over time.
• Are able to qualify for a lower interest rate than your current loan.

If you're considering refinancing, compare your refinance options carefully to determine whether switching to a 15-year mortgage makes sense.
