A Roth IRA doesn't earn a fixed interest rate — the return depends entirely on what you invest in
A Roth IRA is a container, not an investment. The interest or growth you earn comes from whatever you put inside it: a savings account, a CD, stocks, bonds, mutual funds, or a mix. A bank might advertise a Roth IRA savings account earning 4.5% annually, but that 4.5% is what the savings account earns, not what the Roth IRA itself generates. If you hold individual stocks inside your Roth, you earn whatever those stocks return — which could be 15% one year and negative 8% the next, or anywhere in between.
The real advantage of a Roth IRA is not the interest rate. It is that whatever you earn — whether it is 2% from a CD or 10% from stock funds — grows tax-free and you withdraw it tax-free in retirement. That tax shelter is worth far more than chasing a slightly higher interest rate in the wrong place.
Key Takeaways
- A Roth IRA earns whatever return the investments inside it generate; the account itself has no interest rate.
- Conservative options like savings accounts and CDs inside a Roth typically earn between 4% and 5.5% annually, depending on the bank and current rates.
- Stock-based investments (individual stocks, index funds, mutual funds) historically average around 10% annually over long periods, but fluctuate year to year and can lose value.
- The tax-free growth and tax-free withdrawals in retirement are the Roth's main benefit, not the interest rate itself.
- Your choice of investment inside the Roth should match your age, risk tolerance, and how long until you retire — not just the advertised rate.
What you can hold inside a Roth IRA and what each typically earns
Most Roth IRAs are held at banks or brokerages, and each institution offers different investment options. A bank-based Roth might let you choose a savings account, a CD, or a money market account. A brokerage-based Roth gives you access to stocks, bonds, mutual funds, and exchange-traded funds (ETFs).
Savings accounts and money market accounts inside a Roth currently earn between 4% and 5.5% annually at most banks, though rates change frequently. These are the safest option — your principal does not fluctuate — but the return is modest and does not keep pace with historical stock returns.
Certificates of Deposit (CDs) locked inside a Roth typically earn between 4.5% and 5.8% annually, depending on the term (3 months, 1 year, 5 years, etc.). Longer terms usually pay slightly more. Your money is locked until the CD matures, and early withdrawal carries a penalty.
Bond funds and individual bonds earn interest payments that vary by type and current market conditions. Treasury bonds currently yield around 4% to 5%, corporate bonds often yield 5% to 7%, and high-yield bonds can pay 8% or more — but carry higher default risk. Bond prices also move with interest rates, so the value of your holding can drop if rates rise.
Stock funds and individual stocks do not pay a fixed rate. The S&P 500 index has returned an average of roughly 10% annually over the past 50 years, but that includes years of 30% gains and years of 40% losses. A single company stock might return 50% or lose 60% in a year. Over decades, stocks have historically outpaced inflation and bonds, but the path is volatile.
How your age and timeline affect what you should hold
The longer your money sits in the Roth before you need it, the more risk you can afford to take. Someone 25 years old with 40 years until retirement can weather a stock market crash because there is time to recover. That person might hold 90% stocks and 10% bonds inside the Roth. Someone 60 years old with 5 years until retirement cannot afford a 30% drop, so they might hold 40% stocks and 60% bonds or CDs.
This is why comparing interest rates alone is misleading. A 5% CD sounds better than a stock fund that returned 3% last year, but if you are 30 years old, the stock fund's long-term average of 10% will likely build far more wealth by the time you retire. Conversely, if you are 62, the 5% CD is probably the right choice because you need stability more than growth.
The difference between nominal return and real return
A savings account earning 4.5% sounds good until you account for inflation. If inflation is running at 3%, your real return — the actual purchasing power you gain — is only 1.5%. This matters over decades. A dollar in a 4.5% savings account grows to about $5.10 in 30 years, but if inflation averages 3%, that $5.10 buys what $2.40 buys today. A stock fund averaging 10% annually, after 3% inflation, gives you a real return of roughly 7%, and that same dollar grows to about $7.60 in purchasing power.
This is why many financial advisors recommend holding stocks or stock funds in a Roth if you have decades until retirement. The higher nominal return is necessary just to stay ahead of inflation and build real wealth.
How to find current rates for savings accounts and CDs in a Roth
Banks and brokerages update their Roth IRA rates frequently, sometimes weekly. You can compare rates directly on the websites of major banks (Chase, Bank of America, Ally, Marcus, etc.) and online banks (Ally, Wealthfront, Betterment). Most show the annual percentage yield (APY) clearly on the Roth IRA product page.
For CDs, the rate depends on the term length and the bank. A 1-year CD at one bank might pay 5.2%, while a 5-year CD at the same bank pays 5.5%. Comparison sites like Bankrate and DepositAccounts let you filter by term and sort by rate, though you will still need to visit each bank's website to open the account.
For stocks, bonds, and funds, there is no "rate" to compare — you are comparing historical performance and fees. A brokerage like Fidelity, Vanguard, or Charles Schwab will show you the past 1-year, 5-year, and 10-year returns of any fund you are considering, along with the expense ratio (the annual fee charged to hold it).
Why fees matter as much as the return itself
A mutual fund that returns 9% annually but charges 1% in fees leaves you with 8%. An index fund that returns the same 9% but charges 0.05% leaves you with 8.95%. Over 30 years, that 0.9% difference compounds into tens of thousands of dollars in lost wealth.
When comparing investments for your Roth, always check the expense ratio. Index funds and ETFs typically charge 0.03% to 0.20% annually. Actively managed mutual funds often charge 0.5% to 2% or more. For savings accounts and CDs, there are usually no fees, but the rate itself is lower to account for the bank's costs.
What happens if your Roth IRA loses money
If you hold stocks or stock funds and the market drops 20%, your Roth balance drops 20%. You have not lost the tax benefit — the loss is not taxable, and any future gains will still grow tax-free. But your account value is lower, and if you need to withdraw money soon, you will get less than you put in.
This is why time horizon matters. A 30-year-old can afford to hold 100% stocks because a market crash is a temporary setback with decades to recover. A 65-year-old cannot, because they may need the money within a few years. The Roth's tax advantage does not protect you from market risk — only diversification and a long timeline do.
Frequently Asked Questions
Can I move my money between investments inside my Roth IRA without penalty?
Yes. You can sell a CD or stock fund and buy a different investment inside the same Roth IRA without triggering taxes or early withdrawal penalties. The only cost is any trading fees your brokerage charges (usually zero for stocks and funds at major brokerages) and any early withdrawal penalty from the CD itself if it has not matured.
What is the difference between a Roth IRA at a bank versus a brokerage?
A bank Roth IRA typically offers only savings accounts, CDs, and money market accounts — safe, low-return options. A brokerage Roth IRA offers stocks, bonds, mutual funds, and ETFs, giving you access to higher historical returns but more volatility. You can hold a Roth at both simultaneously if you want.
Does the interest I earn in a Roth IRA count toward my annual contribution limit?
No. The contribution limit (currently $7,000 per year for those under 50) is the amount of money you deposit, not the earnings. If you contribute $7,000 and it grows to $8,000, the $1,000 gain does not count against next year's limit. This is one of the Roth's major advantages.
Is a Roth IRA a good place to keep an emergency fund?
No. A Roth is designed for retirement savings. You can withdraw your contributions (not earnings) before retirement without penalty, but doing so defeats the purpose of the account and reduces your long-term wealth. Keep your emergency fund in a separate high-yield savings account outside any retirement account.
What if I want a may provide return in my Roth IRA?
A CD or savings account inside a Roth gives you a may provide return with no market risk. Currently, you can find CDs paying 5% to 5.8% annually. The trade-off is that this return is lower than the historical average for stocks, so your wealth will grow more slowly over decades.
