A Fidelity Roth IRA is a retirement account type, not a checking or savings account

A Fidelity Roth IRA is a retirement savings account that holds investments—stocks, bonds, mutual funds, exchange-traded funds (ETFs)—not cash sitting idle like a checking or savings account would. The "Roth IRA" part is the account structure (set by the IRS), and "Fidelity" is the brokerage firm that holds it for you. You fund it with after-tax money, and the investments grow tax-free. When you withdraw in retirement, you pay no federal income tax on the gains.

A checking account is for spending money now. A savings account holds cash and earns a small interest rate. A Roth IRA is designed to hold money you won't touch for decades, invested to grow. Fidelity doesn't pay you interest on cash sitting in the account—they charge you to hold it. If you want your money to earn anything, you have to buy investments inside the Roth IRA.

Key Takeaways

  • A Fidelity Roth IRA is an investment account, not a place to park cash like a checking or savings account.
  • You choose what investments go inside the Roth IRA—Fidelity provides the account structure and holds the investments for you.
  • Money in a Roth IRA grows tax-free and can be withdrawn tax-free in retirement, but you cannot touch it penalty-free before age 59½ in most cases.
  • Fidelity offers a money market fund or sweep feature that holds uninvested cash, but this is a temporary holding place, not the account's purpose.
  • If you want a place to keep emergency cash earning interest, you need a separate savings account; a Roth IRA is for long-term retirement investing.

How a Roth IRA differs from a checking or savings account

A checking account lets you spend money immediately—you write checks, use a debit card, or transfer funds. A savings account holds cash and earns interest (usually a fraction of a percent). Both are deposit accounts: the bank holds your money and pays you interest. You can withdraw anytime without penalty.

A Roth IRA is a retirement account. You contribute money (up to $7,000 per year if you are under 50, or $8,000 if you are 50 or older, as of 2024), and that money must be invested in something—you cannot just leave it as cash. The IRS has rules: you cannot withdraw earnings before age 59½ without paying income tax and a 10% penalty in most cases. Your contributions can come out anytime penalty-free, but earnings are locked until retirement.

The tax treatment is opposite too. Interest from a savings account is taxable income. Gains in a Roth IRA are not taxed when you withdraw them in retirement. That tax-free growth is why the Roth IRA exists.

What happens to cash you deposit into a Fidelity Roth IRA

When you send money to Fidelity to fund your Roth IRA, it lands in a cash sweep account or money market fund by default. This is temporary. The cash sits there earning almost nothing (often less than 1% annually) until you tell Fidelity what to buy. You then place an order to purchase stocks, mutual funds, ETFs, or bonds inside the account.

Fidelity does not automatically invest your money. You have to log in, choose what to buy, and execute the trade. If you leave cash sitting in the sweep account for months, it earns almost nothing. This is why a Roth IRA is not a savings account—the account structure expects you to invest, not hold cash.

Some people use a Roth IRA as a short-term holding place while they decide what to invest in, but this defeats the purpose. The longer your money sits uninvested, the less time it has to grow tax-free. If you need a place to keep emergency cash earning interest, open a high-yield savings account at a bank or credit union instead.

Investment options inside a Fidelity Roth IRA

Fidelity offers thousands of investments you can hold inside a Roth IRA: individual stocks, mutual funds (including Fidelity's own funds), ETFs, bonds, and options (if you are an experienced trader). You can also hold cash in the money market sweep, but again, this is not the intended use.

The account itself does not earn interest or pay you anything. Fidelity makes money by charging trading commissions (though many stock and ETF trades are commission-free) and by managing the cash sweep account. You make money by choosing investments that grow in value. If you buy a stock that rises 50%, that gain is yours and grows tax-free inside the Roth. If you buy a mutual fund that pays dividends, those dividends reinvest tax-free inside the Roth.

This is fundamentally different from a savings account, where the bank pays you interest. In a Roth IRA, you are responsible for choosing investments and accepting the risk that they might lose value.

Contribution limits and withdrawal rules for a Roth IRA

You can contribute up to $7,000 per year to a Roth IRA (or $8,000 if you are 50 or older), but only if you have earned income that year. You cannot contribute more than you earned. This is different from a savings account, where you can deposit as much as you want.

You can withdraw your contributions anytime without penalty or tax. If you contributed $5,000 and the account grew to $7,000, you can pull out the $5,000 contribution whenever you need it. The $2,000 in gains, however, is locked until age 59½ (with rare exceptions like disability or a first home purchase up to $10,000 lifetime).

A savings account has no such restrictions. You can withdraw all your money anytime. A Roth IRA is designed to stay invested for decades, which is why the tax benefits are so valuable.

When to use a Roth IRA versus a savings account

Use a Roth IRA if you have earned income, want to invest for retirement, and can leave the money alone for at least several years. The tax-free growth makes it powerful for long-term wealth building. Fidelity's Roth IRA is a good choice if you want low fees and a wide range of investments.

Use a savings account if you need to keep money accessible for emergencies, upcoming expenses, or short-term goals. A high-yield savings account at a bank or credit union will earn 4% to 5% annually (rates vary), which is far better than the money market sweep inside a Roth IRA. A savings account is also FDIC-insured up to $250,000, so your money is protected if the bank fails.

Many people use both: a Roth IRA for retirement investing and a savings account for emergencies. They serve different purposes and should not be confused.

Fidelity's cash management features inside a Roth IRA

Fidelity offers a money market fund (usually Fidelity Government Money Market Fund or similar) that you can hold inside your Roth IRA. This is the closest thing to a savings account within the account. It holds cash and earns a small yield, currently around 5% annually (rates change). However, this is still not a savings account—it is an investment you hold inside the Roth IRA.

Fidelity also offers sweep accounts that automatically move uninvested cash into a money market fund. This prevents your cash from sitting idle earning nothing. But again, this is a temporary holding place while you decide what to invest in, not the account's purpose.

If you want to be conservative and hold mostly cash inside your Roth IRA, you can do that. But you are still using a retirement account structure, with all its contribution limits and withdrawal restrictions. A savings account remains a better choice for money you might need soon.

Frequently Asked Questions

Can I use a Fidelity Roth IRA like a savings account to hold emergency cash?

Technically yes, but it is not wise. You can hold cash in a money market fund inside the Roth IRA, but you are limited to $7,000 per year in contributions, and you cannot withdraw earnings penalty-free before age 59½. A high-yield savings account has no contribution limits and lets you withdraw anytime. Use a savings account for emergencies and a Roth IRA for retirement investing.

What happens if I leave cash in my Fidelity Roth IRA without investing it?

The cash sits in a money market sweep account earning minimal interest (currently around 5% annually, but rates vary). You are not earning the tax-free growth that makes a Roth IRA valuable. If you do not plan to invest soon, move the money to a high-yield savings account instead.

Does Fidelity charge me to hold a Roth IRA?

Fidelity does not charge an annual account fee for a Roth IRA. They make money through trading commissions (though many trades are commission-free) and by managing the cash sweep account. However, some mutual funds charge expense ratios, which reduce your returns over time.

Can I transfer money from a savings account to a Roth IRA?

Yes, you can move money from a savings account to fund a Roth IRA contribution, but only up to the annual limit ($7,000 or $8,000 depending on age) and only if you have earned income that year. The money then becomes subject to Roth IRA rules—you cannot withdraw earnings penalty-free before age 59½.

What is the difference between a Fidelity Roth IRA and a Fidelity savings account?

A Fidelity savings account (if Fidelity offered one, which they do not as a primary product) would hold cash and earn interest with no contribution limits or withdrawal restrictions. A Fidelity Roth IRA is a retirement account where you invest money, with annual contribution limits and penalties for early withdrawal of earnings. They are completely different products for different purposes.
