IRA interest depends entirely on what you put your money into
An IRA itself does not earn interest. An IRA is a container—a tax-advantaged account type. The money inside it earns returns based on what you choose to invest in: a savings account, a money market fund, bonds, stocks, mutual funds, or some combination.
If you put $5,000 in an IRA and leave it in cash, it sits there earning nothing (or nearly nothing). If you put that same $5,000 into a bond fund inside the IRA, it earns whatever that bond fund earns. The IRA wrapper does not add returns—it just shields those returns from taxes until you withdraw the money.
This is the distinction most people miss: the account type and the investment type are separate decisions. You choose both.
Key Takeaways
- An IRA is a container for investments, not an investment itself, so it produces no returns on its own.
- What your IRA earns depends on what you invest the money in—savings accounts, bonds, stocks, or funds—not on the IRA type.
- A savings account inside an IRA might earn 4 to 5 percent annually, while stock funds have no may provide return and can lose value.
- The tax advantage of an IRA is that earnings grow without being taxed each year, but you still owe taxes when you withdraw in retirement.
- Different IRA providers offer different investment options, so the same IRA type can produce very different returns depending on where you open it.
What actually earns money inside an IRA
When you open an IRA, you fund it with your own money. That money then goes into whatever investment vehicle you select. The investment—not the IRA—is what generates returns.
Common choices include a high-yield savings account (currently earning around 4 to 5 percent annually, though this changes), a money market fund (similar range), bonds or bond funds (varies by type and maturity), or stock funds and individual stocks (no may provide return; can go up or down). Some people split their IRA across multiple investments.
The bank or brokerage holding your IRA sets the menu of what you can invest in. A bank-based IRA might offer only savings accounts and CDs. A brokerage-based IRA might offer thousands of mutual funds, ETFs, and individual stocks. The same IRA type—say, a Traditional IRA—can produce completely different returns at different institutions because the underlying investments are different.
How the tax shelter actually works
The real value of an IRA is not the returns themselves—it is that those returns are not taxed year to year. In a regular taxable account, if you own a stock fund that gains $1,000 in a year, you owe taxes on that $1,000 that year, even if you do not sell. In an IRA, that $1,000 gain sits untaxed. The next year, if it gains another $1,000, that is also untaxed. This compounds over decades.
With a Traditional IRA, you pay taxes on the money when you withdraw it in retirement. With a Roth IRA, you pay taxes on the money going in, but withdrawals in retirement are tax-free. Either way, the earnings inside the account grow without annual tax drag.
This tax shelter is valuable regardless of what you invest in. A savings account earning 4.5 percent inside an IRA keeps all 4.5 percent. A savings account earning 4.5 percent in a taxable account loses some to taxes each year, depending on your tax bracket.
Why different IRAs at different banks produce different results
You might open a Traditional IRA at Bank A and a Roth IRA at Brokerage B. Both are IRAs. Both have the same tax rules. But if Bank A only offers a savings account earning 4.5 percent, and Brokerage B offers a stock fund that has averaged 8 percent over the past decade, your Roth will grow faster—not because it is a Roth, but because the underlying investment is different.
This matters when you are deciding where to open an IRA. A bank will advertise its IRA savings account rate. A brokerage will show historical returns of its funds. Neither is lying, but they are showing you different things. The rate or return you see is the rate or return of the investment inside the IRA, not a feature of the IRA itself.
If you want predictability, a savings account or CD inside an IRA gives you a fixed rate. If you want growth potential, stock or bond funds offer that—but with no may provide and the possibility of loss.
What you actually control about IRA returns
You control three things: where you open the IRA (which determines what investments are available), what you invest in (which determines the return potential), and how long you leave the money untouched (which determines how much compounding happens).
You do not control market returns. If you invest in a stock fund and the market drops 20 percent, your IRA drops 20 percent. If the market rises 15 percent, your IRA rises 15 percent. The IRA protects you from taxes on those moves, but not from the moves themselves.
You also do not control inflation. If your IRA earns 3 percent but inflation is 4 percent, your money is losing purchasing power. This is why many people choose to invest IRAs in stocks or stock funds rather than savings accounts—the historical long-term return of stocks is higher, which better outpaces inflation over decades.
Comparing what different investments earn inside an IRA
| Investment Type | Current Typical Range | may provide? | Risk Level |
|---|---|---|---|
| High-yield savings account | 4–5% annually | Yes, up to FDIC limit | None (FDIC insured) |
| Money market fund | 4–5% annually | No, but very stable | Very low |
| Bond fund | 3–6% annually (varies) | No | Low to moderate |
| Stock fund or ETF | No typical range; historical average ~10% long-term | No | Moderate to high |
| Individual stocks | Highly variable | No | High |
These ranges change with interest rates, market conditions, and economic cycles. A savings account rate that is 4.5 percent today might be 3 percent next year. A stock fund that averaged 10 percent over 30 years might return 5 percent or negative 15 percent in any given year.
The point of showing this table is not to predict what you will earn, but to show that your choice of investment matters far more than your choice of IRA type. A Roth IRA in a savings account will earn less than a Traditional IRA in a stock fund, because the investment is the driver, not the account type.
How to think about IRA returns over time
IRAs are designed for long holding periods—decades, ideally. Over short periods, returns are unpredictable. Over long periods, they tend to stabilize. A stock fund might lose 30 percent in a bad year but gain 20 percent in a good year. Over 30 years, the ups and downs average out to a more consistent long-term return.
This is why the age you open an IRA matters. If you are 25 and open an IRA, you have 40 years for compounding to work. If you are 55, you have 10 years. The longer the timeline, the more you can afford to take short-term volatility in pursuit of higher long-term returns.
A financial advisor or your IRA provider can show you historical returns of specific funds you are considering. Those past returns do not predict future ones, but they give you a sense of what kind of volatility and growth to expect.
Frequently Asked Questions
Does the IRA itself pay interest like a bank account?
No. An IRA is just a tax-sheltered account structure. It does not generate returns. The investments inside it do. If you put cash in an IRA and never invest it, it earns nothing.
Can I move my IRA to a different bank if I find a better interest rate?
Yes. You can transfer an IRA from one institution to another without tax penalties. This is called a trustee-to-trustee transfer. You can also withdraw the money and roll it into a new IRA within 60 days, though this is riskier because you have to complete the transfer yourself. Ask your new IRA provider how to do this—they usually handle the paperwork.
What happens to my IRA earnings when I retire and start withdrawing?
With a Traditional IRA, withdrawals are taxed as ordinary income, including both the money you contributed and all the earnings. With a Roth IRA, may have access to withdrawals are tax-free. Either way, the earnings are no longer sheltered from tax once you take the money out.
Is a stock fund inside an IRA safer than a stock fund outside an IRA?
No. The IRA does not make the investment safer. A stock fund is a stock fund. The IRA just means you do not pay taxes on the gains or losses year to year. If the fund drops 20 percent, it drops 20 percent whether it is in an IRA or not.
How do I know what rate my IRA savings account is earning right now?
Log into your IRA account online or call your provider. They will show you the current rate on your savings account or the recent performance of any funds you own. Rates change frequently, so check periodically if you want to know whether to move your money elsewhere.
