President Trump wants to let people use their 401(k) funds for a down payment, but whether or not that's a good idea depends on both the economy and your long-term situation.
401(k) funds are currently restricted unless you're over 59½ or qualify for a special exemption to withdraw them early. Otherwise, you'll have to pay a hefty penalty. The Trump administration wants to add home down payments to the list of exemptions so people can use their retirement savings to unlock homeownership.
Details about that potential program, like how much of a 401(k) could be used toward a down payment, aren't clear.
But no matter what the program entails, factors like the long-term appreciation of your home, or its increase in value over time, and the annual return of your 401(k) all determine whether that's actually a good idea.
The Big Picture
Using a 401(k) to help fund a down payment is ultimately a choice between two different wealth building paths.
A 401(k) is based on long-term market investing, whereas buying a home entails leverage and forced savings.
Over the past decade, those approaches have produced very different results on average.
The S&P 500 is the most widely used index to reference the stock market, and it has grown rapidly over the last decade. It has averaged roughly 11% to 13% in annualized growth, according to the Motley Fool. That translates to an investment's growth of 2.3 to 2.8 times its original amount over 10 years.
The housing market has also seen fast growth. U.S. home prices rose about 88% between 2015 and 2025, according to the Federal Reserve Bank of St. Louis’s Case-Shiller National Home Price Index.
Equities have historically outperformed home price appreciation, but that excludes important differences like liquidity, taxes, mortgage interest rates, savings from rent, and risk tolerance.
That comparison is a good starting point, but it's incomplete. A 401(k) dollar isn't the same as a dollar paid toward a down payment. Stock market returns on a 401(k) are liquid after you're 59.5, while housing returns come with a mortgage and are paired with a monthly pay-down.
What Different Scenarios Could Mean for You
Let's say you're deciding whether to take $40,000 from your 401(k) versus using that money for a down payment. If you invest in an S&P 500 index fund over 10 years and it grows at a roughly 12% annualized rate, that means your money will grow to roughly $124,000 before taxes and fees.
That doesn't include continued contributions and employer matches, which can further boost your money.
If you use that $30,000 for a down payment on a $400,000 home, and home prices rise by 88% over the next decade, that portion of equity tied to that home might grow to roughly $75,000. But with a mortgage, you'll also be paying down your loan and earning equity over time while the whole value of the home grows.
This table assumes you leave your 401(k) untouched.

So, if you're looking at what nets you more, the answer is buying a home in this simplified scenario. Taxes, employer match, and ongoing contributions can all affect the long-term picture.
We don't know the specifics of Trump's program yet. Factors like the exact amount of your 401(k) you can use for a down payment you can use are still up in the air, but you can use the calculator below to get an idea of what different scenarios mean for you.
Keep in mind that home appreciation and 401(k) returns can vary significantly over time. Housing prices in particular can fluctuate with market conditions.
Our calculator compares two ways of using retirement savings over a 30-year period: leaving your 401(k) untouched and letting it grow, or using some of that money to help buy a home. It lets you track both home equity and your remaining retirement savings if you don't use your full 401(k) amount. The scenarios in this calculator aren't guaranteed. It shows what would happen if the assumptions you choose stay constant for 30 years.
In the first scenario, the calculator assumes your entire 401(k) balance stays invested for 30 years and grows at the annual rate you enter. In the second scenario, you use part of your 401(k) balance as a down payment on a home. The rest of the 401(k) stays invested.
Keep in mind that our calculator doesn't assume you keep contributing to a 401(k), and continued contributions make a massive difference in growing your funds.
When does using a 401(k) for a Down Payment Make Sense?
Whether using a 401(k) as a down payment for a home makes sense hinges on your personal situation.
If you can comfortably save for retirement, have emergency reserves, and can buy a home without touching your 401(k), pulling retirement funds might not make much financial sense.
There are multiple scenarios where you won't need to touch retirement funds to make a down payment, like:
- If you qualify for a VA loan, which has limited eligibility but no down payment requirement.
- If you qualify for (and can afford) a low down payment option through conventional loans. Many first-time homebuyers qualify for down payments as low as 3%. FHA loans are another option, with down payments as low as 3.5% for qualifying buyers.
- If you qualify for a state or local down payment assistance program.
There are other scenarios where accessing 401(k) funds for a down payment might be a good option. If you're stuck in a high-rent market and you're years away from affording a down payment, a 401(k) can help you turn what would be rent payments into equity.
The Bottom Line
Using your 401(k) as a down payment on a home can be profitable in the long run, but whether it's actually a good idea depends on your personal situation.
Continued contributions to a 401(k) can net you a significant amount of money, and buying a home can come with maintenance costs, property taxes, and insurance expenses. Home value appreciation isn't a sure thing, and can vary significantly depending on where you live.
But by buying a home, you're also unlocking home equity that can be used later in the form of a HELOC, home equity loan, or other way to tap into home equity. And if you continue contributing to your 401(k) in addition to tapping into its value to purchase a home, you could get the best of both worlds.
