Roth IRA Interest Rates: Why There Isn't One (and What Grows Instead)
Roth IRA interest rates don't exist as such: the account earns whatever you hold inside it. How cash, CDs, bonds and funds grow, and what to check.

Quick summary (TL;DR)
- There are no Roth IRA interest rates in the usual sense, because a Roth IRA is a tax wrapper; what it earns depends entirely on the investments or deposits you hold inside it.
- Banks that advertise a Roth IRA rate are quoting the rate on a savings account or CD held inside the IRA, and FDIC insurance covers retirement deposits up to $250,000 per depositor per bank.
- Stocks and stock funds have no stated rate at all; their value rises and falls, which brings higher long-term potential and real risk of loss.
- A common mistake is leaving contributions as uninvested cash, which may earn little or nothing depending on how your provider handles it.
- Growth inside a Roth IRA isn't taxed each year, and qualified withdrawals are tax-free.
In this guide
There are no Roth IRA interest rates in the way a savings account has one, because a Roth IRA is an account type, not an investment. Roth IRA interest rates you see advertised are really the rates on a savings deposit or CD held inside the account; everything else you hold there grows, or shrinks, with the market.
That's why two people with the same Roth IRA balance can end up with very different results. This guide explains what actually earns money inside a Roth IRA, what you can expect from each option as of 2026, and the cash mistake that quietly costs beginners. It's education, not investment advice.
Does a Roth IRA have an interest rate?
No. A Roth IRA is a tax wrapper, and its return is whatever its holdings earn. The IRS describes a Roth IRA as an individual retirement account where qualified distributions are tax-free; it says nothing about a rate, because the account doesn't set one.
Think of it as a container. You decide what goes in it:
| What you hold inside the Roth IRA | How it earns | Is there a stated rate? | What protects it |
|---|---|---|---|
| Savings deposit at a bank (IRA savings account) | Interest | Yes, set by the bank and can change | FDIC insurance up to the limit |
| Certificate of deposit (IRA CD) | Fixed interest for a term | Yes, fixed for the term | FDIC insurance up to the limit |
| Money market fund at a broker | Income from short-term debt | A yield that changes; not a promised rate | Not FDIC-insured; can lose value |
| Treasury bills, notes or bonds | Interest, plus price changes if sold early | Yes, set at purchase | Backed by the US government; price can move |
| Stock or bond funds, ETFs | Dividends, interest, price changes | No | No protection from market losses |
| Individual stocks | Dividends, price changes | No | No protection from market losses |

Why do some banks advertise a Roth IRA rate?
Because they offer savings accounts and CDs that can be opened as IRAs, and those deposits do pay interest. When a bank quotes a "Roth IRA rate", it's the rate on that deposit product, not something every Roth IRA earns.
What to know about bank Roth IRAs:
- They're insured deposits. The FDIC says deposits in all of a person's "certain retirement accounts", which include traditional and Roth IRAs, are added together and insured up to $250,000 per depositor at the same bank.
- The menu is narrow. A bank IRA usually holds only that bank's savings and CD products, not stock funds.
- Rates move. Savings rates can change at any time, and CD rates are fixed only for the term. Compare current rates on the bank's own site before opening.
A bank IRA can make sense for money you want stable, but it's a very different plan from long-term investing. Our investing for beginners guide explains how to decide what kind of growth your timeline actually needs before you choose where to open the account.
What can you hold in a Roth IRA, and how does each grow?
At a brokerage, almost any mainstream investment: cash, money market funds, CDs, Treasuries, bonds, funds and stocks. Each one earns in a different way, with different risks.
Cash and money market funds
These are the closest thing to a "rate" at a broker. A money market fund pays a yield that changes with short-term interest rates. It's a mutual fund, not a bank deposit, and the FDIC lists mutual funds among products it doesn't insure.
CDs and Treasuries
A CD or Treasury held to maturity pays a known interest rate. You can usually buy brokered CDs and Treasuries inside a brokerage IRA. Our guides on how to invest in CDs and how to buy Treasury bonds cover the details and the catches, such as early-withdrawal penalties or price changes if you sell before maturity.
Stock and bond funds
Funds have no rate at all. Their value moves daily, and your long-run result depends on the market, fees and how long you stay invested. Many long-term Roth IRA savers hold broad, low-cost index funds; our explainer on index funds for beginners shows what to compare.
What return can you expect from a Roth IRA?
Nobody can tell you in advance, and anyone who promises a fixed Roth IRA return on stocks is a red flag. What you can do is see how much the assumed rate changes the outcome.
Example (hypothetical): you contribute $5,000 at the end of each year for 30 years, a total of $150,000, and it grows at a steady assumed rate. Real returns are never steady; these numbers only show the effect of the rate.
| Assumed yearly return | Approximate value after 30 years | Growth on top of $150,000 contributed |
|---|---|---|
| 1% | $173,900 | About $23,900 |
| 3% | $237,900 | About $87,900 |
| 5% | $332,200 | About $182,200 |
| 7% | $472,300 | About $322,300 |
Two lessons from the math:
- Small differences compound. Going from 3% to 5% adds far more than two points' worth of money over 30 years.
- Higher potential comes with real risk. Assets that have historically produced higher long-run returns, like stocks, also have years with large losses. Safer deposits make the path smoother but usually grow more slowly.
A quick rule of thumb: divide 72 by the yearly rate to estimate how many years money takes to double. At 6%, about 12 years; at 2%, about 36.
Is your uninvested cash earning anything?
Possibly very little, and this is the most common Roth IRA mistake. When you contribute, the money usually lands as cash. Unless you buy something, it may sit in a default cash position whose yield depends on your provider.
How to check your own account:
- Look at the holdings, not just the balance. If it shows only cash or a "core" or "sweep" position, your contribution isn't invested.
- Find the cash yield on your provider's site. Some pay a competitive money market yield; others pay much less.
- Decide on purpose. Holding cash briefly is fine. Holding it for years by accident usually isn't what people intend.
On safety: SIPC protects customers if a brokerage firm fails, up to $500,000 including a $250,000 limit for cash, but SIPC states it does not protect against the decline in value of your securities. So "protected" and "can't lose value" are not the same thing.
Do you pay tax on what a Roth IRA earns?
Not while it stays inside the account, and not at all on qualified withdrawals. Interest, dividends and gains inside a Roth IRA aren't taxed year to year, unlike the same holdings in a regular taxable brokerage account.
The catch is the withdrawal rules. Earnings come out tax-free only in a qualified distribution, which generally means the account has met the five-year requirement and you're 59½ or meet another condition. Our explainer on the Roth IRA 5-year rule breaks down those clocks.
Because the shelter is so valuable, some people hold their highest-growth investments in a Roth IRA and keep cash for emergencies elsewhere. Our guide on emergency fund vs investing covers why a separate cash cushion usually comes first.
Outside the US, the closest equivalents, such as the UK's stocks and shares ISA or Canada's TFSA, work the same way: the account has no rate, and the holdings decide the return.

Frequently asked questions
What is the interest rate on a Roth IRA?
A Roth IRA has no interest rate of its own. If you hold a CD or savings deposit inside it, you earn that product's rate; if you hold funds or stocks, your return is whatever they gain or lose.
Can you lose money in a Roth IRA?
Yes, if you hold investments such as stocks, bonds or funds, their value can fall. Bank deposits inside an IRA are FDIC-insured up to the limits, and SIPC protection at a broker covers a firm's failure, not market losses.
Is a Roth IRA CD a good idea?
It can suit money you'll need within a few years or someone who wants no price swings. Over decades, CDs have historically tended to grow more slowly than diversified stock funds, so many younger savers use them for only part of the account.
Do you pay tax on interest earned in a Roth IRA?
No tax is due each year on interest, dividends or gains earned inside a Roth IRA. Qualified withdrawals are tax-free; earnings taken out early can be taxed and penalized.
Does a Roth IRA grow on its own?
Only if the money is invested or deposited in something that earns a return. Cash left idle in the account may earn very little, so check where your contributions actually sit.
