Traditional IRA interest rates are mostly a misunderstanding. A traditional IRA is a tax wrapper, not a product with one set rate, so what it earns depends entirely on what you hold inside it: a bank CD pays fixed interest, while a brokerage IRA earns market returns.
Key Takeaways
- An IRA is a container (a tax-advantaged account), not an investment. There is no single “IRA interest rate” set by the IRS.
- A bank IRA holding a CD paid a national average of 1.71% for a 12 month term as of August 2026, per the FDIC.
- A brokerage IRA holding stock funds earns market returns, not interest. The S&P 500 has averaged roughly 10% a year since 1957, though single years vary widely (Fidelity).
- Quoted “IRA interest rates” are almost always bank CD or savings rates, because only bank products carry a stated rate.
- For 2026 you can contribute up to $7,500 to an IRA, or $8,600 if you are 50 or older, per the IRS.
- Growth inside a traditional IRA is tax-deferred, which is why a low-income year can open a window to convert to Roth so future growth becomes tax-free.

Traditional IRA: 2026 Numbers
Figures for the 2026 tax year, verified against IRS primary sources.
Do traditional IRAs earn interest?
Sometimes yes, sometimes no, and the answer depends on what is inside the account. A traditional IRA (Individual Retirement Arrangement) is a tax wrapper defined by the tax code, not a savings product with its own posted rate. The IRS treats the IRA as the account; the interest or return comes from the assets you place in it.
If you open a traditional IRA at a bank and buy a certificate of deposit, that CD pays a fixed rate of interest, so the IRA “earns interest” in the everyday sense. If you open a traditional IRA at a brokerage and buy a stock index fund, the account earns market returns (dividends plus price growth), which is not interest at all. The same question for workplace plans is answered in whether a 401(k) earns interest.
This is the single most common point of confusion, and it is why people search for a “traditional IRA interest rate” that does not exist as one universal number. Understanding how retirement accounts actually grow starts with separating the container from the contents.
What determines the interest rate on a traditional IRA?
The rate is determined by whatever you buy inside the IRA, not by the IRA itself. There is no IRS-set rate and no default rate. Two people can both own a traditional IRA and earn completely different results in the same year because they hold different assets.
Bank products carry a stated rate. A CD locks in a fixed percentage for a set term, and an IRA savings or money market account pays a variable rate the bank can change. Investment products do not carry a stated rate: bonds pay a coupon plus price movement, and stock funds deliver market returns that are unknown in advance.

Why are quoted traditional IRA interest rates usually CD rates?
Because only bank products carry a rate you can quote. When a website advertises “IRA interest rates,” it is almost always listing IRA CD or IRA savings rates from banks and credit unions, since those are the only IRA holdings with a fixed, postable number.
A brokerage cannot advertise a rate for a stock fund, because nobody knows next year’s return. So the rate tables you see are a snapshot of bank deposit products, comparable to the rates you would weigh when learning how CDs are taxed. They are real, but they describe one narrow slice of what an IRA can hold, not the account itself.
This matters for retirement planning. A retiree who assumes an IRA simply “pays interest” may keep a large balance in low-yield CDs when their goals call for a different mix. The choice between bank and brokerage holdings is one piece of the broader traditional versus Roth decision and of how a 401k compares to a Roth IRA.
How does tax-deferred compounding work in a traditional IRA?
Inside a traditional IRA, interest, dividends, and gains are not taxed each year; tax is deferred until you withdraw. That lets the full balance compound without an annual tax drag, which is the core advantage of the wrapper regardless of what it holds.

Compounding means each year’s earnings can themselves earn in the next year. In a taxable account, you might owe tax on interest or dividends annually, shrinking the base that compounds. In the IRA, that same interest or growth stays invested. The trade-off is that withdrawals are taxed later as ordinary income, and traditional IRA withdrawal rules plus required minimum distributions at age 73 or 75 eventually apply, under SECURE 2.0.
That deferred tax is a feature and a future bill. A larger tax-deferred balance can mean larger taxable RMDs down the road, which is why many retirees weigh whether to move some of that money into a Roth while brackets are favorable.
How do traditional IRA interest rates tie into Roth conversions?
Because growth is tax-deferred, not tax-free, a low-income year can be a natural time to convert. When your taxable income dips, converting part of a traditional IRA to a Roth is taxed at that year’s lower rate, and all future growth in the Roth is then tax-free rather than tax-deferred.
The math is about brackets, not a posted rate. For 2026 the 24% federal bracket runs up to $201,775 for single filers and $403,550 for married couples filing jointly, so retirees often model how much they can convert while staying inside a target bracket. A conversion in a low-income year is one common example, and how much to convert is a modeling question, not a rule of thumb.
None of this depends on an “interest rate.” It depends on what the account holds, how much it has grown tax-deferred, and the tax cost of moving it. A fee-only fiduciary can model whether a multi-year Roth conversion fits a given situation.

Frequently asked questions
Do traditional IRAs earn interest automatically?
No. A traditional IRA does not pay interest on its own. It earns interest only if you hold an interest-bearing product inside it, such as a bank CD or an IRA savings account. If you hold stock or bond funds instead, the account earns market returns rather than interest.
What is the interest rate on a traditional IRA?
There is no single rate. The rate depends on what you buy inside the IRA. A bank IRA CD carried a national average of 1.71% for a 12 month term in August 2026 per the FDIC, while a brokerage IRA holding funds earns variable market returns with no stated rate.
Is an IRA a savings account or an investment?
An IRA is a tax-advantaged account that can hold either. At a bank it usually holds savings products like CDs; at a brokerage it holds investments like funds, stocks, and bonds. The IRA is the wrapper, and the holdings determine how it grows.
Why do bank IRA rates look so much lower than stock market returns?
Bank IRA rates reflect low-risk, FDIC-insured deposit products, so they are modest and predictable. Market returns from a brokerage IRA have historically been higher over long periods but are not insured and can fall in any given year.
How much can I contribute to a traditional IRA in 2026?
For 2026 the IRA contribution limit is $7,500, or $8,600 if you are age 50 or older (a $1,100 catch-up), according to the IRS. Contribution limits are separate from how the account earns.
Does tax-deferred growth mean my IRA is tax-free?
No. Traditional IRA growth is tax-deferred, meaning you pay ordinary income tax when you withdraw. Converting to a Roth is one way retirees make future growth tax-free instead, though the converted amount is taxed in the year of conversion.
Can I hold both a CD and stock funds in the same traditional IRA?
Often yes, depending on the provider. Some custodians let you hold a mix of deposit products and investments, while a pure bank IRA may only offer CDs and savings. The blend you choose is what sets your overall return.
