How to Pay Off a 30-Year Mortgage in 15 Years: Tips and Tricks

Want to know how to pay off a 30-year mortgage in 15 years? A homeowner can use one of a few strategies to pay off a home loan early and save a boatload of interest.

Here’s what you need to know about how to pay a 30-year mortgage in 15 years and what to consider before you do.

Paying Off a 30 Year Mortgage Faster

When you start paying on a 30-year mortgage, most of your payment will go toward interest rather than the principal (the amount you borrowed). This makes it hard to pay down your mortgage and build equity.

Over time, the percentage of your payment that goes toward interest vs. principal will change. Toward the end of your 30-year loan, you will pay more toward the principal than interest. This is what’s known as mortgage amortization.

Instead of following the amortization schedule, paying more on your mortgage — in one way or another — will reduce the principal more quickly, which means you’ll pay less interest on your loan.

Should You Pay Off Your Mortgage Faster?

Paying off your mortgage faster may give you a sense of accomplishment and save you a lot of money in interest charges, but if it takes you further away from your financial goals, it may not be worth it to you. Consider what you value most before deciding to put extra money toward paying off your mortgage.

Pros and Cons of Paying Off Your Mortgage Early

Paying off a 30-year mortgage in 15 years has benefits, but in some cases, it may not make sense to. Consider these pros and cons.

Pros

Cons

Higher monthly payment
Own your home outright sooner You will lose the home mortgage interest tax deduction (if you itemize)
Ultimately no mortgage payment
Build equity faster Less money available for retirement, higher-interest debt, a rainy day fund, etc.
Save money on interest Gains by investing could trump interest saved

Factors to Consider Before Paying Off Your Mortgage Faster

While paying off your mortgage early — a few zealous borrowers aim to pay off a mortgage in five years — can save you tens of thousands of dollars in interest, the lost opportunities from not having money readily available for other things could be more valuable. Think about:

•   Have I been contributing enough to my retirement plans as an employee?

•   Have I been funding retirement as a self-employed person?

•   Do I have three to six months of expenses, or more, if my personal situation calls for it, in an emergency fund?

•   Am I able to secure a lower rate or shorter term for a refinance to pay off my mortgage faster? Would a cash-out refinance make sense?

•   Do I have higher-interest debt like credit card debt or student loans I should tackle first?

•   Have I set up a college fund for the kids?

•   Does my mortgage carry a prepayment penalty (unlikely for loans originated after January 2014)?

How to Pay Off a 30-Year Mortgage Faster

There are at least three methods to pay off a 30-year mortgage in 15 years if that’s your goal.

Make Extra Principal Payments

Paying more toward principal is the primary way to pay off a 30-year mortgage early.

Here’s an example of how interest adds up: Assuming you buy a $350,000 house and put 10% down on a 30-year mortgage at 5.5%, this mortgage calculator shows that total interest will be $328,870. Even by the 120th payment, you will have paid only $55,000 of the $315,000 principal and will have paid nearly $160,000 in interest.

Putting just $200 more per month toward principal, you’d save $80,837 in interest and pay off the mortgage six years and four months earlier.

Switch to Biweekly Payments

Biweekly payments are half-payments made every two weeks instead of a full payment once a month. Making biweekly payments instead of monthly payments results in one additional payment each year.

Using the example above, making one full, extra mortgage payment each year will reduce the amount of time it takes to pay off your 30-year mortgage by five years.

Look Into Refinancing

Refinancing your loan into one with a lower interest rate and/or a shorter term can help you pay off your mortgage faster. A shorter term usually comes with a lower interest rate, so you’re saving on interest while also paying your mortgage off sooner than 30 years.

Refinancing to a lower interest rate will reduce your monthly mortgage payment, so if you continue to make the higher payment, you’ll pay your mortgage off faster.

The Takeaway

There are a few ways to pay off a 30-year mortgage in 15 years. Paying off your mortgage early will result in substantial interest savings, but the tradeoff for many borrowers is not having extra money to put toward retirement and other purposes.

FAQ

Is it cheaper to pay off a 30-year mortgage in 15 years?

The amount of interest you’ll save by paying off your mortgage in 15 years instead of 30 is substantial.

Why shouldn’t you pay off your mortgage early?

Homeowners who haven’t fully funded their retirement accounts, who don’t have an emergency fund, or who have other debt with high interest rates may not want to pay off a mortgage early. Also, those who think they can earn a better return on their money with investments may not want to pay off their mortgage early. (They need to keep in mind that past performance is not necessarily indicative of future returns.)

How do you pay off a 30-year mortgage in half the time?

Paying more toward the principal early in the mortgage can help you cut the amount of time you spend paying on your mortgage in half. The good news is you don’t have to make double payments to cut the amount of time you pay on your mortgage in half. Because each payment will reduce the principal, you will pay less overall.

Are biweekly mortgage payments a good idea?

Biweekly mortgage payments, or half-payments made every two weeks, will add a full mortgage payment every year. Using this method can take a few years off your mortgage.
