Roth IRA investment options: What to put inside your Roth IRA

Key takeaways
Opening a Roth IRA and contributing money is only the first step. You still need to choose investments inside the account, with options including stocks, funds, bonds, or other assets, for your money to grow.
Since qualified withdrawals are completely tax-free, holding assets with the highest growth potential (like stock index funds) inside a Roth IRA can maximize the tax benefit over time.
Younger investors may lean heavily toward stocks for long-term growth, while those closer to retirement typically shift toward a more balanced mix of stocks, bonds, and stable-value options.
Why what you invest in matters more inside a Roth IRA
A Roth IRA grows tax-free. Contributions go in after tax, but all qualified withdrawals in retirement — including decades of investment growth — are completely tax-free. There are no required minimum distributions, so the account can continue compounding for as long as you live.
This tax structure has a direct implication for what you should invest in:
The assets with the highest long-term growth potential benefit the most from being inside a Roth IRA, because every dollar of growth is shielded from taxes.
An S&P 500 index fund that doubles over 10 years generates the same growth whether it's in a taxable brokerage account or a Roth IRA, but in the Roth, you keep all of it.
In a taxable account, you'd owe capital gains tax on the appreciation when you sell.
How do Roth IRA investment options compare?
Here's a side-by-side overview of the most common investment types available inside a Roth IRA.
Investment type | Growth potential | Risk level | Income | Best for |
Index funds / ETFs | High (tracks broad market) | Moderate (market risk) | Varies (some pay dividends) | Core long-term growth holding |
Target-date funds | Moderate to high (shifts over time) | Moderate, decreasing over time | Varies | Hands-off investors who want auto-rebalancing |
Actively managed mutual funds | Moderate to high | Moderate to high | Varies | Investors who want professional stock picking |
Dividend stock funds | Moderate | Moderate | Regular dividends (tax-free in Roth) | Income-focused growth with reinvestment |
Bond funds | Low to moderate | Low to moderate | Regular interest | Stability and income as you near retirement |
REITs | Moderate to high | Moderate to high | Regular dividends (often high yield) | Real estate exposure with tax-free dividends |
CDs (within an IRA) | Low (fixed rate) | Very low (FDIC-insured) | Fixed interest | Capital preservation near or in retirement |
Roth IRA investment options explained
Each investment type serves a different role in a retirement portfolio. Here's what to know about each one.
Index funds and ETFs
Index funds and ETFs track a market index — like the S&P 500, the total U.S. stock market, or an international stock index — and give you diversified exposure to hundreds or thousands of companies through a single investment. They're the most popular choice for Roth IRAs because they combine broad diversification, very low fees (often 0.03% to 0.20%), and strong long-term growth potential.
The main difference between the two is how they trade. Index mutual funds are priced once a day at market close. ETFs trade throughout the day like individual stocks. For long-term retirement investors, this distinction rarely matters.
Because of the Roth IRA's tax-free growth, index funds and ETFs that track high-growth segments of the market (like U.S. or international stocks) can be especially valuable inside this account.
Target-date funds
A target-date fund is a single fund that automatically adjusts its mix of stocks and bonds as you approach a target retirement year. A "2055 fund," for example, starts with a heavily stock-weighted portfolio and gradually shifts toward bonds and stable-value assets as 2055 approaches. This glide path is designed to reduce risk as you get closer to needing the money.
Target-date funds are a practical choice for investors who want a diversified, age-appropriate portfolio without managing the allocation themselves. The trade-off is slightly higher fees than a basic index fund and less control over the specific asset mix.
Actively managed mutual funds
Mutual funds pool money from many investors to buy a diversified mix of stocks, bonds, or other assets, managed by a professional fund manager. Unlike index funds, which passively track a benchmark, actively managed funds try to outperform the market through stock selection and timing.
The trade-off is higher fees. Expense ratios for actively managed funds can range from 0.50% to 1.50% or more. Research consistently shows that most actively managed funds underperform their benchmark index over long periods after fees, which is why many long-term investors favor index funds. However, some investors prefer the potential for outperformance or want exposure to specific strategies.
Dividend stock funds
Dividend stock funds invest in companies that regularly distribute a portion of their profits to shareholders. Inside a Roth IRA, these dividends grow tax-free, and if reinvested, they can compound significantly over time. In a taxable account, dividends would be subject to annual taxes, making the Roth IRA a particularly efficient home for this type of investment.
Dividend-paying companies tend to be more established and stable, which can provide a smoother ride than pure growth stocks, though dividends are never guaranteed.
Bond funds
Bond funds invest in a diversified mix of government, municipal, or corporate bonds. They tend to be more stable than stock funds and provide regular interest income, making them a common choice for investors who are nearing or in retirement and want to reduce their portfolio's volatility.
Inside a Roth IRA, bond interest is tax-free, which can be an advantage since bond interest in a taxable account is taxed as ordinary income. However, some financial advisors argue that bonds are better held in tax-deferred accounts (like a traditional IRA or 401(k)) where the ordinary income tax deferral may provide a greater benefit, while stocks belong in the Roth where the tax-free growth has more upside. This is the concept of "asset location," and it's worth considering as your portfolio grows.
Real estate investment trusts (REITs)
REITs are companies that own and operate income-producing real estate — apartment buildings, office towers, warehouses, data centers. They're required to distribute at least 90% of taxable income as dividends, which makes them high-yield but also means REIT dividends are typically taxed as ordinary income in a taxable account.
Holding REITs inside a Roth IRA eliminates this tax drag entirely. Dividends grow tax-free, and qualified withdrawals are tax-free. This makes the Roth IRA one of the most efficient accounts for REIT exposure.
CDs within a Roth IRA
While not a traditional "investment," CDs held inside an IRA can provide capital preservation and a guaranteed fixed rate. This can be useful for the portion of your Roth IRA that you want to keep stable, particularly if you're approaching retirement and want to protect a portion of your balance from market volatility. The interest earned is tax-free within the Roth, and FDIC insurance protects the principal up to $250,000 per depositor, per insured institution.
What does a Roth IRA allocation look like at different ages?
Your age and timeline are the biggest factors in deciding how to allocate your Roth IRA. Here's an example of how the mix might shift over time.
Remember: This is just an example. Your actual allocation should reflect your risk tolerance, your other retirement accounts (like a 401(k)), and how much you've already saved.
| Age 25 | Age 40 | Age 55 | Age 65+ |
Stocks (index funds, ETFs) | 80–90% | 65–75% | 45–55% | 30–40% |
Bonds (bond funds) | 5–10% | 15–25% | 30–40% | 40–50% |
REITs / alternatives | 5–10% | 5–10% | 5–10% | 5–10% |
CDs / stable value | 0% | 0–5% | 5–10% | 10–20% |
2026 Roth IRA contribution and income limits
Before choosing your investments, make sure you're eligible to contribute and know the current limits. These are the current limits for 2026.
The contribution limit applies across all of your traditional and Roth IRAs combined. If your income exceeds the phaseout range, you cannot contribute directly to a Roth IRA, though some investors use a "backdoor Roth" strategy.
| 2026 |
Contribution limit (under 50) | $7,500 |
Contribution limit (50+, including catch-up) | $8,600 |
Roth IRA income limit — single (full contribution) | MAGI below $153,000 |
Roth IRA income limit — single (phaseout) | $153,000–$167,999 |
Roth IRA income limit — joint (full contribution) | MAGI below $242,000 |
Roth IRA income limit — joint (phaseout) | $242,000–$251,999 |
Bottom line
A Roth IRA's tax-free growth makes it one of the most valuable accounts in your retirement plan, but only if you invest the money inside it. For most long-term investors, a core allocation to low-cost index funds or ETFs provides broad diversification and positions your money to benefit most from the Roth's tax advantages. As you approach retirement, shifting some of that allocation toward bonds, REITs, and stable-value options can help protect what you've built.

Frequently Asked Questions (FAQ)
Can I hold CDs in a Roth IRA?
Yes, you can hold CDs inside a Roth IRA. The interest you earn is tax-free, and qualified withdrawals in retirement are also tax-free. CDs within a Roth IRA can be useful for the portion of your retirement savings you want to keep stable and protected from market volatility.
The trade-off is that CDs offer lower returns than stock or bond funds, so holding too much of your Roth IRA in CDs may limit your long-term growth potential, particularly if you're decades from retirement.
What is the best Roth IRA investment for beginners?
For most beginners, a low-cost total stock market index fund or S&P 500 index fund is a strong starting point. These funds provide instant diversification across hundreds of companies, charge very low fees, and have historically delivered competitive long-term returns.
If you prefer a fully hands-off approach, a target-date fund matching your expected retirement year can handle the allocation and rebalancing for you automatically.
How much should I allocate to bonds versus stocks in my Roth IRA?
Your allocation depends on your age, goals, and risk tolerance. A common starting framework is to subtract your age from 110 to estimate the percentage in stocks — a 30-year-old might target 80% stocks and 20% bonds, while a 60-year-old might aim for 50/50.
Because the Roth IRA's tax-free growth benefits high-growth assets most, some advisors suggest keeping your stock allocation in the Roth and holding more bonds in tax-deferred accounts like a 401(k) or traditional IRA.
What happens if I contribute more than the annual limit?
Excess contributions are subject to a 6% penalty tax per year for as long as the excess remains in the account. To avoid this, withdraw the excess amount and any earnings on it by your tax filing deadline (typically April 15 of the following year).
The 2026 contribution limit is $7,500 ($8,600 if you're 50 or older), and this limit applies across all of your traditional and Roth IRAs combined.
