Does a Roth IRA Earn Interest? What a “Schwab Roth IRA Interest Rate” Really Means

I am not a financial advisor or tax professional. Everything here is educational content based on my own experience managing my accounts and on publicly available rules and published rate disclosures — not personalized financial advice. Rates change constantly; always confirm current numbers on the brokerage’s own rate page before acting.

One of the most common searches that lands people on retirement-account articles is some version of “Charles Schwab Roth IRA interest rate.” It is a completely reasonable thing to type into Google, and it is also a question with no answer — because a Roth IRA does not have an interest rate. Not at Schwab, not at Fidelity, not anywhere. The question hides a misunderstanding about what a Roth IRA actually is, and that misunderstanding costs real money. I have watched people leave a Roth IRA funded but uninvested for years because they assumed the account itself was paying them something.

So let me take the question apart: what a Roth IRA is, what the “interest rate” you are seeing actually refers to, and what to do about the gap between the two.

A Roth IRA Does Not Have an Interest Rate

A Roth IRA is not a product. It is a tax wrapper — a legal designation applied to an account that tells the IRS how the money inside it should be taxed. It is much closer to a job title than to a savings account. Saying “what is the interest rate on a Roth IRA” is like asking what mileage a garage gets. The garage does not drive anywhere. What matters is what you parked inside it.

Here is the practical consequence. When you open a Roth IRA at Schwab, Fidelity, or Vanguard and transfer $7,000 into it, that money does not start earning a return. It sits in the account’s default cash position. Your return, from that moment until you buy something, is whatever the brokerage pays on idle cash — and at most major brokerages, that number is close to zero.

The Roth IRA’s power is that whatever the investments inside it earn comes out tax-free in retirement. But it has to earn something first. The wrapper does not generate returns. The contents do.

What a “Schwab Roth IRA Interest Rate” Usually Refers To

When people find a Schwab rate and conclude it is their Roth IRA’s interest rate, they have almost always found one of three different numbers:

• The cash sweep rate. Every brokerage account has a default place where uninvested cash goes. At Schwab this is the Schwab Bank Sweep (or, in certain account types, a money fund sweep). This rate applies only to cash you have not invested — and it is typically very low.
• A money market fund yield. Funds like Schwab’s SWVXX are investments you buy inside the account. Their yields are published and move with short-term rates. This is a real return, but you only get it if you actively purchase the fund.
• A CD or Treasury rate. Brokerages sell brokered CDs and Treasury securities that can be held inside an IRA. These genuinely pay interest at a stated rate. Again: only if you buy them.

Only the first of those three applies automatically. The other two require you to place a trade. That distinction is the entire point of this article.

The Gap Between Idle Cash and Invested Cash

This is where the vague question becomes an expensive one. The spread between what a brokerage pays on swept cash and what a plain money market fund pays at the same firm has been enormous in recent years.

Where your Roth IRA dollars sit	Who decides	Approximate yield
Default cash sweep (uninvested)	Automatic — the default	Very low; Schwab’s published rate on uninvested brokerage cash was 0.01% APY as of early October 2026
Money market fund (e.g. SWVXX)	You buy it	Roughly 3.5%–3.7% around the same date, moving with short-term rates
Brokered CD or Treasury	You buy it	A stated rate, fixed for the term
Stock or bond index fund	You buy it	No interest rate at all — returns come from dividends and price changes

Read that first row against the second. On a $7,000 contribution, the difference between the default sweep and a money market fund was roughly $250 over a year — for one trade. On a Roth IRA that has been sitting in cash for three or four years, the cumulative cost of never having placed that trade is substantial, and it compounds for the rest of the account’s life because those dollars never got invested.

It is worth noting that Schwab restricts certain account types from the automatic money fund sweep, which means for many retirement accounts the uninvested balance genuinely does sit in the low-yield bank sweep until you do something about it.

Where Roth IRA Growth Actually Comes From

If “interest rate” is the wrong frame, what is the right one? Inside a Roth IRA, money grows through three mechanisms, and only the first is interest in the technical sense:

• Interest — from bonds, CDs, Treasuries, money market funds, and swept cash. A stated rate on a stated balance.
• Dividends — cash distributions from stocks and stock funds. Not a fixed rate; they rise and fall with company earnings.
• Capital appreciation — the change in the price of what you own. Historically the largest component of long-term returns, and the one with no rate attached at all.

When long-run projections use a figure like 7% a year, that is not an interest rate anyone is promising. It is a historical average of all three components for a diversified stock portfolio, and it describes a bumpy multi-decade path, not a predictable annual payment. If you want to see how that assumption plays out over a long horizon, the Roth IRA growth calculator lets you change the rate and watch what happens.

If You Genuinely Want a Stated Interest Rate Inside Your Roth IRA

Some people searching for a Roth IRA interest rate are not confused at all — they want a predictable, interest-bearing holding inside the tax wrapper. That is entirely possible, and these are the usual options:

• Money market funds. The simplest place to park cash you have not decided about. Yields float, there is no lock-up, and the trade takes one minute.
• Brokered CDs. A fixed rate for a fixed term, purchasable inside an IRA at most brokerages. Selling before maturity means selling at market price, which may be below face value.
• Treasury securities. Bills, notes, and bonds bought directly or through a fund. A Roth IRA already shelters the interest from federal tax, so holding Treasuries here means giving up the main benefit of their state-tax treatment — worth knowing, though not a reason to avoid them.
• Bond index funds. Not a fixed rate, but a yield that behaves far more like interest than stocks do.

The honest caveat: if your Roth IRA has a 30- or 50-year horizon, filling it with interest-bearing holdings is usually the wrong call. The entire advantage of the Roth structure is that growth comes out untaxed, and over long periods stocks have produced far more growth to shelter than bonds have. A Roth IRA stuffed with CDs is a tax shelter protecting a return that was never going to be taxed much anyway. For a child’s account in particular, I would read what to actually hold inside a child’s Roth IRA before defaulting to anything that quotes a rate.

The Mistake This Confusion Causes

Here is the failure mode, and it is common enough that it is worth stating plainly. Someone opens a Roth IRA — often a custodial Roth IRA for a child, after reading that early contributions are powerful — transfers the money in, sees the balance appear, and stops. The contribution is made. The account exists. Nothing is invested.

Because the balance does not go down, nothing looks wrong. The statement arrives, the number is the same as last month, and the assumption that the account is “earning” quietly survives. On a custodial Roth IRA opened for an eight-year-old, a few years of uninvested cash at the front end removes the most valuable compounding years the account will ever have.

What To Do With Idle Cash in a Roth IRA

1. Find your cash balance. Log in and look for “cash available to invest” or the sweep balance — not the total account value, which includes everything.
2. Check what the sweep is paying. Every brokerage publishes this. If it starts with “0.0”, you have found your problem.
3. Decide if the money has a job yet. If you know what you want to own long term, buy it. If you do not, a money market fund is a reasonable holding pen that pays something while you decide.
4. Set contributions to invest automatically. Most brokerages let you schedule a recurring purchase, not just a recurring transfer. A transfer alone leaves the money in the sweep. This is the step that prevents the problem from recurring.
5. Check dividend reinvestment. If it is off, distributions pile up as idle cash and the same problem returns in miniature every quarter.

Does Schwab Specifically Pay Interest on a Roth IRA?

To answer the original search as directly as I can: Schwab does not pay an interest rate on a Roth IRA, because the Roth IRA is the wrapper. Schwab pays a rate on the uninvested cash sitting in the sweep, and that rate has recently been close to zero. Schwab also sells money market funds, CDs, Treasuries, and bond funds that you can hold inside the Roth IRA and that do pay meaningful yields. Which of those you end up with is your decision, not a feature of the account.

The same answer applies at Fidelity, Vanguard, and everywhere else, with different sweep mechanics and different default behaviour. Some brokerages sweep uninvested cash into a money fund by default, which is meaningfully better for the account owner; others sweep to a bank program paying far less. It is worth knowing which one you have. For Schwab’s broader fee and investment-option picture, I have written a fuller Charles Schwab Roth IRA review, and the custodial version is covered in the Schwab custodial Roth IRA review.

Frequently Asked Questions

Does a Roth IRA earn interest?

Not by itself. A Roth IRA is a tax wrapper, not a product, so it has no interest rate of its own. Money inside it grows only through whatever you buy: interest from bonds, CDs, Treasuries or money market funds; dividends from stocks and stock funds; and changes in the price of what you hold. Uninvested cash sitting in the account’s default sweep earns whatever the brokerage pays on idle cash, which at major brokerages has recently been close to zero.

What is the Charles Schwab Roth IRA interest rate?

There isn’t one, because the Roth IRA is the account wrapper rather than an interest-bearing product. The Schwab rate people find is usually the cash sweep rate paid on uninvested cash. Schwab’s published rate on uninvested brokerage cash was 0.01% APY in early October 2026, while its money market funds yielded roughly 3.5% to 3.7% around the same time. Rates change constantly, so check Schwab’s own rate disclosures for current figures.

Does Schwab pay interest on uninvested cash in an IRA?

Yes, but very little. Uninvested cash goes into a default sweep — at Schwab typically the bank sweep — and earns the published sweep rate, which has recently been a small fraction of a percent. Certain account types are restricted from the automatic money fund sweep, so for many retirement accounts the cash genuinely sits in the low-yield option until you buy something. Purchasing a money market fund yourself is the usual fix.

Is a Roth IRA like a savings account?

No. A savings account is a product with a stated interest rate, held at a bank and insured by the FDIC. A Roth IRA is a tax designation applied to an account that can hold almost any investment. The balance in a Roth IRA can fall, which a savings account balance does not. The confusion is understandable but it leads people to leave Roth IRA contributions uninvested for years, assuming the account is paying them something.

How do I get a better return on cash in my Roth IRA?

Find the cash balance in your account, check what the default sweep is paying, and then either buy the long-term investment you actually want or move the cash into a money market fund while you decide. Then set your recurring contribution to invest automatically rather than just transfer, because a transfer alone leaves the money in the sweep. Finally, check that dividend reinvestment is switched on, or distributions will pile up as idle cash every quarter.
