15-year vs. 30-year mortgage comparison

Thirty years is the most common loan term in the United States, with 15-year terms a common alternative. Your loan term has a big effect on your monthly mortgage payment and how much interest you pay over the life of your loan. Learn more about a 15-year vs. 30-year mortgage, and the role your loan term plays in determining how much you pay for your home.

Key takeaways:

• The 30-year mortgage spreads out your loan repayment and helps keep your monthly payment down, even though you pay more in overall interest.
• The 15-year mortgage lets you pay off your home in half the time and saves you money on interest, with the trade-off being a higher monthly payment.
• Borrowers who want lower monthly payments and more cash‑flow flexibility may prefer a 30‑year loan, while those focused on faster equity growth and long‑term savings may benefit from a 15‑year option.

15- vs. 30-year mortgage terms: What's the difference?

The obvious difference between a 15-year mortgage and a 30-year mortgage is the loan's term. That difference has a big effect on how your loan is repaid.

Life of the loan

The obvious difference between a 15-year and a 30-year loan is the length of repayment.

If your first mortgage payment was due Jan. 1, 2026, you’d make your final payment on a 15-year loan on Dec. 1, 2040. With a 30-year loan, your last payment would be due Dec. 1, 2055.

Interest rates

Your loan’s mortgage rate affects the monthly payment and how much interest you’ll pay overall.

In general, lenders charge higher interest rates for riskier loans. The shorter a loan's term, the less risk of default. So, when comparing 15-year vs. 30-year mortgage rates, the former is usually lower than the latter.

Approval requirements

Qualifying for a mortgage with a 15-year term can be more difficult because you need to show the lender that you can handle the larger monthly payment. Some lenders also have higher credit score requirements for 15-year mortgages.

How much more does a 30-year mortgage cost?

Say you’re buying a $400,000 home. If you make a 5% down payment, you’ll borrow $380,000 with a mortgage and pay for private mortgage insurance (PMI). Excluding PMI, property taxes, homeowners insurance, and HOA fees, a 30-year mortgage would save you $558 a month, but you’d pay $310,454 more in total interest.

You can use the mortgage calculator from Rocket Mortgage to estimate your monthly payment based on your loan amount, loan term, interest rate, and other factors.

What affects your payment difference

When comparing these options, remember that your total monthly housing costs are more than just principal and interest. Several financial factors will affect your 15- vs. 30-year mortgage payment difference, including:

• Down payment. A larger down payment reduces your loan amount and can help you avoid PMI.
• Interest rate. Loans with shorter terms generally have lower interest rates, which directly reduces how much interest you pay.
• Amortization schedule. Shorter loan terms also have a compressed amortization schedule, meaning each monthly payment is structured to reduce your principal balance significantly faster from year one. You can create your own amortization schedule using the mortgage amortization calculator from Rocket Mortgage.
• Property taxes. Property tax is assessed by your local government and is typically paid with monthly installments in an escrow account.
• Homeowners insurance. Lenders require homeowners insurance to protect the property, which adds to your monthly obligation. It’s also often paid with monthly deposits into an escrow account.
• HOA fees. If you buy a home in a community with a homeowners association, HOA fees must be factored into your overall affordability budget.

Pros and cons of 15-year mortgages

Fifteen-year mortgages let you pay off your loan more quickly, but there are downsides you need to keep in mind before committing to one.

Pros

There are many reasons to consider getting a 15-year mortgage.

• Own your home in 15 years. Getting a 15-year mortgage means paying your loan off in half the time of a 30-year loan.
• Save on interest. Lower interest rates and shorter periods for interest to accrue mean that 15-year loans cost far less in the long run than 30-year mortgages.
• Build home equity faster. With a 15-year mortgage, you make larger payments toward your loan principal each month compared with a 30-year mortgage. That helps you build home equity more quickly. In just a few years, you could have enough equity to get a home equity loan¹ or home equity line of credit (HELOC) that you can use for renovations, buying another property, or debt consolidation. Rocket Mortgage currently doesn’t offer HELOCs.

Cons

Fifteen-year mortgages aren't all upsides. It's also important to think about their drawbacks.

• Higher mortgage payments. The monthly payment is higher to clear the loan balance in half the time. This can increase your monthly housing overhead, leaving you with less breathing room in your budget.
• Fewer lender options. Fifteen-year mortgages are less common than 30-year loan terms. Not every lender offers 15-year loans, so you may have fewer options when shopping around for a loan.
• Higher financial opportunity cost. Locking up a big portion of your monthly income in a fixed housing payment leaves you with less cash for maximizing retirement accounts, paying tuition, or handling unexpected personal expenses.
• Reduced borrowing power. The higher monthly payment will increase your debt-to-income (DTI) ratio, which can limit how much you can borrow. You may have to settle for a smaller or less expensive home than you may be able to afford with a 30-year mortgage.

Pros and cons of 30-year mortgages

Though 30-year loans cost more in the long run, there are many good reasons to consider applying for one.

Pros

There are a few good reasons to choose a 30-year loan over a 15-year mortgage.

• Lower monthly payments. Thirty-year mortgages have a lower monthly payment because you're stretching repayment over more time. That can free up cash in your budget for other expenses or investments.
• Potential to buy a more expensive house. If you can afford a $2,500 monthly principal and interest payment, a 30-year loan could help you buy a more expensive home, assuming the interest rate is the same.
• Easier qualification requirements. The lower payment can reduce your DTI. That may make it easier to qualify for a mortgage and buy a home, especially if you have other debts, such as student loans or car payments.
• More mortgage options. Most mortgages in the United States are 30-year loans, so just about every lender offers them. That means that you'll have plenty of lenders to work with when comparison shopping, giving you a better chance to explore the best rates and terms available.

Cons

Thirty-year mortgages can be more affordable every month, but it's also important to consider their drawbacks.

• Higher interest payments. A 30-year mortgage usually costs more in interest than a 15-year loan because you’re borrowing for a longer period.
• Slower equity build. With a longer repayment timeline, less of each payment goes toward reducing your loan balance early on. That means it may take longer to build enough equity to refinance, sell for a profit, or qualify for a home equity loan or HELOC.
• Longer debt timeline. A 30-year mortgage keeps you tied to a monthly housing payment for a long time, which can make it more difficult to build wealth or pay off your home before retirement.

Options for paying off your 30-year mortgage early

A 15-year mortgage can help you pay off your home faster, but it also locks you into a higher monthly payment for the life of the loan. Some options for paying your loan off early include:

• Make extra payments. If you have extra cash, putting it toward principal payments will reduce your balance faster, so you'll pay off the loan sooner.
• Make biweekly payments. With 52 weeks in a year, making a payment every other week allows you to make the equivalent of 13 monthly payments – one more than you’d make on a monthly payment schedule.
• Refinance: If your income increases and you can afford a higher monthly payment, you can refinance to a 15-year loan.² This would help you pay down the principal faster and save you money on overall interest.
• Recast your mortgage: If your lender allows mortgage recasting, you can make a lump-sum payment toward your principal. Your lender then recalculates your monthly payments based on the lower loan balance.

How to choose between a 15-year and 30-year mortgage

Choosing the right loan term depends on your budget, income stability, life stage, and long-term financial goals. These common scenarios can help you decide which option fits best.

A 15-year mortgage might work best if:

• You want overall savings. If your goal is to pay less total interest and own your home free and clear as fast as possible, a 15-year term is ideal.
• You are nearing retirement. If you want to eliminate major structural debts and be mortgage-free by the time you stop working, matching your loan term to your retirement timeline is a smart strategy.
• You can comfortably afford the payment. If your income allows you to absorb the higher monthly payment without hindering your ability to save for emergencies, invest, or cover daily expenses, the 15-year term makes great financial sense.

A 30-year mortgage might work best if:

• You want budgeting flexibility. The smaller monthly payment frees up cash each month, giving you a valuable financial safety net for unexpected hardships, medical issues, or job changes.
• You want to maximize buying power. Because a 30-year loan features a lower monthly payment, it keeps your DTI lower, allowing you to qualify for a more expensive or larger home that fits your needs.
• You want to prioritize other investments. Keeping your fixed housing obligation low leaves you more cash for retirement savings, stock portfolios, or investment options.

FAQ

Here are answers to common questions about 30-year vs. 15-year mortgages.

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

Yes. If you make extra principal payments and pay off a 30-year mortgage in 15 years, you can save thousands of dollars in interest compared with taking the full 30 years. However, it may still cost more than choosing a 15-year mortgage from the start because 30-year loans usually have higher interest rates.

Am I better off with a 15- or 30-year mortgage?

It depends on your financial priorities. You might be better off with a 15-year mortgage if your primary goal is minimizing interest costs and you can comfortably afford the higher payment. You could be better off with a 30-year mortgage if you prioritize monthly cash flow flexibility, need lower monthly payments, or want to maximize your buying power to get a more expensive home.

Can I pay off a 30-year mortgage early?

Yes, you can pay off a 30-year mortgage early by making extra principal payments, switching to biweekly payments, or refinancing to a shorter term. Doing so allows you to build home equity much faster and save money in total interest on your loan. Most modern lenders allow early payoff without any prepayment penalties, but you should always verify your specific loan terms first.

The bottom line: 15-year vs. 30-year mortgage

Thirty-year mortgages are the most popular and affordable loan option. Fifteen-year loans have a higher monthly payment, which can limit how much house you can afford, but allows you to pay off your loan more quickly and save on overall interest. Make sure to compare 15-year vs. 30-year mortgage pros and cons. Think carefully about whether a 15-year loan is right for you, and consider ways to pay off a 30-year loan more quickly while retaining the flexibility of lower payments typical of longer loans.
