When deciding between certain products, it can be easy to just go with the most popular. But when it comes to choosing the right mortgage product to fit your goals, going with the most popular option may not be the best decision.

The average mortgage length is a good place to start. Learning more about other term length options and the benefits and drawbacks of each one will help you find the right mortgage for you.

What Is The Average Home Loan Length?

Mortgages typically come with a certain amount of time to pay off the loan. This is known as a mortgage term. The most common mortgage term in the U.S. is 30 years. A 30-year mortgage gives the borrower 30 years to pay back their loan.

Most people with this type of mortgage won’t keep the original loan for 30 years. In fact, the typical mortgage length, or average lifespan of a mortgage, is under 10 years. That’s not because these borrowers pay the loan off in record time. It’s more likely that homeowners refinance into a new mortgage or purchase a new home before the term is up. According to the National Association of REALTORS® (NAR), buyers only expect to stay in the home they purchase for a median of 15 years.

So why, then, is the 30-year option the average mortgage term in America? Its popularity has to do with several different factors, including current mortgage rates, the monthly payment, the type of home being purchased or the borrower’s financial goals.

What Are My Mortgage Term Length Options?

There are two types of mortgages: a fixed-rate mortgage or an adjustable-rate mortgage (ARM). When it comes to fixed-rate mortgages versus ARMs, the major difference is that a fixed-rate loan has an interest rate that stays the same throughout the life of the loan.

With an ARM, the interest rate adjusts throughout the loan term. ARMs are also 30-year loans only, while fixed-rate loans have various term options for borrowers.

Most fixed-rate mortgages will have a 30-year or 15-year term, though some lenders offer 20-year terms and some even allow borrowers to choose their own term.

Home buyers should consider all possible home loan options before committing to a mortgage. Let’s dive deeper into these products to get a better understanding of each.

15-Year Mortgage

Some home buyers may opt for a 15-year mortgage because of one major factor: total interest paid. With a shorter mortgage term, borrowers pay off the loan quicker. That means they’ll pay less total interest because they’re paying interest for half the amount of time as a 30-year home loan. An additional benefit to paying the loan off faster is that homeowners will build equity faster and own their home free and clear much sooner.

While a 15-year mortgage has its advantages, many homeowners shy away from this type of loan. While it can save borrowers a lot of money in the long run, it comes with higher monthly payments.

30-Year Mortgage

As we mentioned before, the 30-year mortgage is the most common home loan term in the U.S. With this mortgage, borrowers have 30 years to pay the loan off, and have a fixed or adjustable interest rate throughout the life of the loan.

Because the payment is spread out over the most amount of time, the 30-year mortgage has the lowest monthly payment of these term length options. However, since you’ll be paying the longest amount of time, you’ll likely pay the most total interest.

20-Year Mortgage

For borrowers who don’t want a 30-year mortgage but think the monthly payment on a 15-year mortgage is a little tight, a 20-year mortgage could be a good compromise. While the standard option for a 20-year mortgage is a conventional loan, they’re also available as VA and FHA loans.

With a term length between the 15-year and 30-year mortgages, you can find some middle ground. For example, 20-year mortgages do have a lower interest rate than a 30-year mortgage and will help you save on overall interest paid throughout the life of the loan. However, you won’t save as much total interest as you would with a 15-year loan. And, while 20-year mortgages have a lower monthly payment than a 15-year and, thus, offer more financial flexibility, they still have a higher monthly payment than a 30-year mortgage.


Rocket Mortgage® has a loan option called YOURgage, which allows you to choose a fixed-rate term of anywhere from 8 – 29 years. This fixed-rate loan is more customized to a homeowner’s financial goals and can give them some control over their monthly payment amount.

Digging Deeper: Shorter Vs. Longer Mortgage Terms

Mortgage term length is one factor that helps determine the monthly payment amount and amount of interest paid over time. When deciding on a mortgage term length, consider the following.

Longer Mortgage Terms

Longer mortgage terms come with higher interest rates and a higher amount of interest paid over the length of the loan. While longer mortgage terms come with higher interest, the advantage borrowers have with these loans are the lower monthly payments.

Since the payment is spread over more years, borrowers will pay less each month. This aspect is what makes 30-year loans a popular type of mortgage among homeowners, especially first-time home buyers. Several factors determine the interest rate a borrower will pay and there are ways to lower the interest rate, including a mortgage buydown.

Shorter Mortgage Terms

Homeowners with 15- and 20-year mortgages can expect to pay higher monthly payments than longer-term loans because they have less time to pay back the loan. The flip side is that they’ll likely have a lower mortgage interest rate and will pay much less total interest over the course of the loan.

15- And 30-Year Term Length Options Compared

We’ve talked a lot about saving money on your monthly payments versus saving money on your total interest. To get a better understanding of just how much the difference between 15- and 30-year mortgages can make, it may be helpful to see it in a real-life example. *For the sake of simplicity, we’ll use the same interest rate for both loans.

15-Year Fixed for $200,000 Mortgage

  • Loan term: 15 years
  • Interest rate: 2.5%
  • Monthly payment: $1,334
  • Total interest paid: $40,044

30-Year Fixed for $200,000 Mortgage

  • Loan term: 30 years
  • Interest rate: 2.5%
  • Monthly payment: $790
  • Total interest paid: $84,487

In the example above, you’d save $544 on your monthly payment each month with a 30-year mortgage. However, with a 15-year mortgage, you’d save $44,443 on total interest.

*Please note, the monthly payments in these examples do not include escrow payments. Total interest paid is based on the borrower keeping the mortgage for its full term and not making extra payments on the loan. Interest rates vary depending on several factors, including a borrower’s credit score, down payment, loan amount, loan type and home location.

Is The Average Mortgage Term Right For Me?

When deciding the right mortgage term for you, it’s important to consider your budget and the long-term financial goals you have. To help with your decision, consider the following questions.

Are You Planning To Buy A Large Home?

Because monthly payments are lower with a 30-year mortgage, you’ll likely be able to afford more house with the long-term loan. If you’re planning on purchasing a large or luxury home, a 30-year mortgage may be a better option.

What Are Your Other Financial Goals?

If you have other financial goals, such as saving for a child’s education or paying off student loans, you may benefit from the low monthly payments offered by 30-year mortgages. The money you’ll save from having a lower monthly payment can go toward saving money or paying off debts. Using the comparison example above, if you opted for a 30-year loan instead of 15-year, you could use the $544 you’d save on your monthly payment to pay off other debts or put into your savings account.

Are You Prepared To Carry The Long-Term Debt?

You’ll need to ask yourself if you’re comfortable with the long-term commitment that comes with a 30-year mortgage. Keep in mind there are ways to pay down the mortgage early, but some lenders charge an early prepayment fee. Before you commit to this long-term debt, ask your lender about prepayment penalties and create a plan for paying the loan off early if you can.

The Bottom Line: Consider All Mortgage Term Options

The average mortgage term is 30 years, but that doesn’t mean you have to get a 30-year loan – or take 30 years to pay it off. While it offers one of the lowest monthly payments among the various term options, this term will likely see you pay the most in total interest if you keep it for 30 years. When choosing your mortgage term, consider your financial goals and monthly budget, talk to a mortgage expert and get the best mortgage rate possible – that goes for whichever term you choose.
