Mutual fund selection and commission-free choices

Fidelity's mutual fund and ETF selection is vast, offering more than 3,800 mutual funds and ETFs can be purchased without paying a commission or transaction fee.

Naturally, Fidelity is a great place to open an IRA if you want to invest in Fidelity-branded mutual funds or ETFs, which are both available in fee-free formats to IRA investors.

Minimum deposit requirement for IRAs

Fidelity doesn't require a minimum deposit to open an IRA. However, many of its own Fidelity-branded mutual funds have $2,500 minimum deposit requirements, so you'll need to make an appropriately sized deposit if you plan on using its mutual funds.

Minimum in investments in individual stocks and ETFs are much lower. If you can afford a single share and cover the commission, you can make your first investment.

IRA fees: maintenance and inactivity fees

Fidelity doesn't charge a maintenance or inactivity fee simply for having common types of accounts such as Roth or traditional IRAs. However, employer-sponsored SIMPLE IRAs are assessed a fee of $25 per year.

Is a Fidelity IRA right for you?

Fidelity has a lot that individual investors should like in an IRA. It offers no-fee IRAs, copious research functionality and retirement tools, plus wide access to international markets and no-minimum account sizes. And while it offers a lot of commission-free funds, its commission prices on trades outside the fee-free list (stocks and stock options) may be less expensive elsewhere.
