It’s a common dilemma: Should you throw extra money toward your mortgage or use those funds to invest? You may think there’s one universal answer, but there’s not. The better choice between paying down your mortgage or investing extra cash comes down to your mortgage interest rate, how long you plan to invest, your tax situation, and how comfortable you are with risk.
Let’s break down those factors—and see how to decide which option is the better use of your money.
The key numbers that drive the decision
When you have extra funds to pay down your mortgage early or invest, it can be difficult to know which choice is best for your financial situation. But the crux of the decision is comparing the numbers: How does your mortgage rate compare with the return you could reasonably expect from investing?
That’s a hard question to answer—impossible, in fact, to predict with certainty. If you expect your investments to earn a higher percentage than what you’re paying in interest on your home loan, investing your extra cash can be a good idea. But if your mortgage rate is close to (or higher than) what you reasonably expect to earn from investing, paying down the loan may be the better idea.
In other words, the higher your mortgage interest rate, the more likely it is that you should pay down your home loan instead of investing.
But two details complicate this math:
- Taxes: If you itemize, you may be able to deduct eligible mortgage interest and lower the after-tax cost of borrowing money. If you take the standard deduction, however, the mortgage interest deduction may not move the needle.
- Risk: The stock market doesn’t guarantee investment returns. But paying down your mortgage gives you a surefire savings based on your interest rate—a detail which can matter more when markets are unsteady.
When paying off your mortgage early makes sense
Your interest rate is 6% or higher
As a general guideline, paying down debt becomes more attractive when the interest rate reaches 6% or higher. However, your investment timeline, emergency savings, taxes, and risk tolerance also matter.
Even with a mortgage rate around 6%, paying off your loan early can save you serious money. For example, let’s say:
- You took out a 30-year mortgage for $350,000.
- Your rate is 6.50%.
- You have 25 years left on your term.
Excluding taxes and insurance, your monthly payment would be around $2,212. About five years into your 30-year loan term, you’d owe approximately $327,201. If you were to start putting an extra $300 toward your payment each month, you’d pay off your loan more than six years earlier and save over $93,000 in interest. That’s some serious savings.
You’re within 10 years of retirement
If retirement is around the corner, the calculations may shift away from growth and toward stability. Eliminating one of your biggest monthly expenses before retirement could provide significant financial relief. It reduces the amount you’ll have to draw from savings each month. You also won’t expose those extra funds to the risk of a market downturn if you put them toward paying down your mortgage instead of investing them.
Market volatility makes you uncomfortable
Investment returns can look great on paper—but if market swings make you nervous, you may not stay invested long enough to earn a meaningful return. Also consider the fact that if you put extra cash into the market and then have to sell investments at a loss during a downturn to cover expenses, you could lock in those losses. You don’t face that same risk when you put the money toward your mortgage.
When investing makes more sense
Your interest rate is below 6%
As a general guideline, investing becomes more attractive when your mortgage rate is below 6%, though some experts use a more conservative cutoff of 5%. Your investment timeline, emergency savings, taxes, and risk tolerance also play key roles in the decision-making process.
As of August 13, 2026, the average mortgage rates for 20- and 30-year fixed-rate mortgages are above 6.50%. If you’ve locked in a mortgage rate below 6.00%, your rate is lower than today’s averages.
Historically, the S&P 500 has delivered an annualized total return of about 10% since 1957. That’s considerably higher than a mortgage rate under 6%—but again, the market doesn’t guarantee returns.
For comparison with the mortgage scenario above, let’s say you currently owe $311,381 on a mortgage with a 4.5% interest rate and about 24 years remaining. Your monthly principal-and-interest payment would be about $1,773, excluding taxes and insurance.
If you begin putting an extra $300 toward your mortgage each month, you could save just over $50,000 in interest and pay off the loan about five and a half years early. Those savings are meaningful, but investing that $300 each month over the same 18.5-year period would result in a balance of nearly $136,000 if the investment earned an average annual return of 7%.
That return isn’t guaranteed, and the nearly $136,000 balance would include your contributions. You’d also still have about five and a half years of mortgage payments remaining.
You aren’t taking full advantage of retirement accounts
If you’re not currently contributing enough to receive your full employer 401(k) match, it’s typically best to do so before putting any extra money toward your mortgage. Your employer is effectively giving you free money toward your retirement account. It’s difficult for most other financial moves to beat that kind of increase.
After that, consider contributing to a Roth IRA. You make contributions with after-tax money, but qualified withdrawals (including investment earnings) can be tax-free in retirement. Depending on your mortgage rate, investment returns, and tax situation, that tax advantage could be more valuable than the guaranteed interest savings from paying down your mortgage early.
You have a long time horizon
The more time you’ve got before you retire, the more time your investments have to grow. You can potentially ride out some market downturns without selling your investments, giving the market time to recover. Someone decades from retirement can usually take on more market risk than someone who plans to retire in a few years—even if they have the same mortgage rate.
In short, if you’ve got a low mortgage rate and plenty of time before retirement, investing extra money may make more sense than paying down the loan early.
You’re not sure how long you’ll stay in the home
If you may sell your home within a few years, consider how easily you may need access to your extra money. Once you put extra funds toward your mortgage principal, that money becomes part of your home equity and you generally can’t access it unless you:
- Sell your home.
- Take out a home equity loan or HELOC.
- Complete a cash-out refinance.
Investing may offer more flexibility, although selling investments can have tax consequences and expose you to market losses.
You don’t have to choose one or the other
Remember, deciding whether to pay off your mortgage isn’t strictly an either-or situation. You can split your extra cash between the two.
Just be sure you’ve covered all your basics before you do either of these things:
- Save three to six months of expenses in an emergency fund.
- Pay off all high-interest debt.
- Contribute enough to your 401(k) to receive your full employer match.
Let’s say you’ve got $1,000 a month to put toward these goals. You could send $500 toward your mortgage principal and invest the other $500 in a Roth IRA. Over 10 years, you’d lower your home loan balance considerably—while building a retirement account with tax advantages. You’ll make less progress on both goals than if you had focused on just one, but you’ll still increase your home equity while investing money for potential growth.
How to get started
Paying down your mortgage
If you decide to focus on making extra mortgage payments, there are a few things to double-check:
- Be certain that your home loan doesn’t have a prepayment penalty. A prepayment penalty could make those extra payments less worthwhile.
- Make sure that your mortgage servicer applies any extra money you pay to your principal instead of a future monthly payment.
- Consider biweekly payments if your servicer offers them without a fee. That means you’ll pay half the usual monthly payment every two weeks. This isn’t mandatory, but it adds up to 26 half-payments a year—which is one extra full payment.
Investing
If you opt to invest your extra monthly income, first:
- Put enough into your 401(k) to receive your full employer match.
- Consider contributing to a Roth IRA. For 2026, the combined contribution limit for traditional and Roth IRAs is $7,500, or $8,600 if you’re 50 or older. Keep in mind that higher earners may not qualify to contribute the full amount to a Roth IRA.
Automating your contributions can also help you avoid spending the money elsewhere each month.
The takeaway
Have some extra money left over after paying your monthly bills? You can put it to good use by either paying down your mortgage or investing it in the stock market.
Each option comes with its own pros and cons. But no matter what you do, it’s worth revisiting the mortgage-vs-investing question periodically or whenever your financial situation changes. Your mortgage rate may stay the same, but other factors likely won’t—such as your income, tax situation, financial goals, and appetite for investment risk.
Frequently asked questions
How does my risk tolerance affect whether I should pay off my mortgage early or invest?
If you have a low risk tolerance and are quick to sell your investments during market swings (even at a loss), you may feel more comfortable putting extra money toward your mortgage. This approach gives you guaranteed interest savings based on your mortgage rate. If you’re willing to ride out market volatility, however, you may prefer investing for the potential of higher long-term gains.
Does it make more sense to pay off my mortgage early or invest during a recession?
You may think that a recession automatically makes paying off your mortgage the smarter choice, but that’s not necessarily true. Sticking with your plan to invest can still make sense if you’ve got time to keep your money invested without selling at a loss. That means you should have enough emergency savings to cover your expenses during a rough patch without liquidating your investments.
Is it better to pay off my mortgage early or invest in a 401(k) and Roth IRA?
If your company matches your 401(k) contributions, consider contributing enough to receive the full match first. After that, whether you contribute more to your 401(k), fund a Roth IRA, or pay down your mortgage depends on factors such as your mortgage rate, taxes, investment timeline, and risk tolerance.
Does paying off my mortgage early or investing affect my credit score more?
Investing your extra money won’t directly affect your credit score. Making extra mortgage payments could improve your score as your balance falls. However, paying off the mortgage will close the account and your score could drop if you have no active installment loans at that time. The final impact depends on the rest of your credit profile.
Can I split my extra money between paying off my mortgage early and investing?
Yes, you can split your extra money between paying off your mortgage early and investing. You just won’t make progress toward either goal as quickly as if you put every dollar toward one or the other.
