What is a 15-year mortgage?

A 15-year mortgage will be paid off completely in 15 years if you make all the payments on schedule. These mortgages typically have a fixed rate, which keeps the interest rate the same for as long as you hold the mortgage. Your costs for property taxes and home insurance can change, though.

15-year mortgages are less common than 30-year home loans, partly because the monthly payments on 15-year loans are higher. That's the case even though rates tend to be lower for 15-year mortgages.

Consider the pros and cons of a 15-year mortgages to decide which home loan is best for you.

Advantages of a 15-year mortgage

Build equity faster

A 15-year fixed-rate mortgage, with its lower interest rate and higher payment amount, builds home equity faster because you pay down the principal balance quicker.

Shorter path to full homeownership

Owning a home free and clear is a goal that burns bright for many people. What matters most to them is a feeling of safety from knowing that their home is fully paid off.

Long-term savings

Lenders are exposed to fewer years of risk on a 15-year mortgage, so they charge a lower interest rate. Half as many years of payment also means you pay half as many years of interest. Let’s compare the principal and interest — not including homeowners insurance, property tax or private mortgage insurance — for a $300,000 mortgage:

  • A 30-year fixed-rate mortgage at 7% has monthly payments of $1,996 and a total interest cost of $418,527 over the life of the loan.

  • A 15-year fixed-rate mortgage at 6.25% has monthly payments of $2,572 and a total interest cost of $163,008 over the life of the loan.

The 15-year loan costs $255,518 less in interest.

Disadvantages of a 15-year mortgage

Larger monthly payments

Monthly principal and interest payments for a 15-year fixed-rate mortgage run about 30% higher than on a 30-year home loan. You also have to pay property taxes, insurance and, if you put less than 20% down, mortgage insurance. This could make it hard to respond to emergencies and other needs. Even if numbers seem doable now, a mortgage is a commitment. Getting out means selling, refinancing or foreclosure.

🤓Nerdy Tip

If you're unsure that you'll always be able to make bigger payments, choose a mortgage with a longer term, then pay extra toward the principal each month. That way, you're still paying down the mortgage more quickly, but you aren't in hot water if there's a month where you afford only the minimum payment.

Opportunity cost

Using more money for monthly mortgage payments means it’s not available for other investments such as home improvements or capturing an employer’s matching contribution to a retirement account.

Tighter range of home affordability

The higher monthly payments for a 15-year mortgage mean you’ll qualify for a lesser amount. That might mean buying a smaller house or forgoing your dream neighborhood. Stretching the loan over 30 years and keeping your payments low could give you more choices.

Is a 15-year mortgage right for you?

A 15-year fixed-rate mortgage is a great tool for borrowers who can afford the higher payments while still saving and investing for retirement. Paying off a mortgage gives many people a feeling of independence, safety and accomplishment.

But if your income is uncertain or variable, avoid the 15-year mortgage. Ask yourself: What would happen if the payments became too much? Do you have a realistic plan to cope, or would you stretch your finances too far?
