Using a Roth IRA to help buy a home
A Roth IRA is funded with after-tax money and grows tax-free — and because you can withdraw your own contributions any time, it can double as a flexible home fund. Here's how it builds.
Why a Roth IRA is so flexible
A Roth IRA is funded with after-tax money and grows tax-free. Two features make it unusually useful for a future home buyer:
- You can withdraw your own contributions at any time, tax- and penalty-free — you already paid tax on that money.
- First-time buyers can also withdraw a limited amount of earnings penalty-free toward a home.
How it builds
Say you contribute $6,000 a year for five years and earn about 6% a year. The dark portion below is your contributions — the part you could withdraw for a home any time:
- Your contributions (withdrawable any time)
- Tax-free growth
After five years you've put in $30,000 — all of which is withdrawable for a home — while roughly $6,000 of tax-free growth keeps working for retirement.
What it means for your mortgage
If you put the $30,000 of withdrawable contributions toward a home, here's how that changes the mortgage on a $400,000 home, versus a 5% down payment:
| 5% down | With the Roth | |
|---|---|---|
| Down payment | $20,000 | $50,000 |
| Mortgage (amount borrowed) | $380,000 | $350,000 |
| Monthly payment | $2,402 | $2,212 |
| Total interest over 30 yrs | $484,669 | $446,406 |
- Total interest paid
Using the account, your monthly payment is about $190 lower and you pay roughly $38,263 less interest over the life of the loan.
Use it thoughtfully
The flexibility is real, but anything you pull out is no longer compounding tax-free for retirement — so treat it as a backup, not the plan. For money you'll need within a year or two, plain high-yield savings is often the safer home. Compare the options across all the US accounts, then run your numbers on the mortgage calculator.
