Why trust this review: every fee, minimum and product detail below comes from Fidelity's own published pricing and fund pages, checked at write time. All the cost math is our own arithmetic on those published numbers, shown in full. We hold no position in and receive no payment from any company named here.
Fidelity is a full-service brokerage — a company that holds your investment account and lets you buy funds, ETFs and individual stocks inside it. Unlike the robo-advisors we've reviewed, it doesn't pick your investments or rebalance them for you by default. You decide what to buy; Fidelity holds it, executes the trade and keeps the paperwork.
for a beginner who wants to buy an index fund and leave it alone, this is about as frictionless and as cheap as the industry gets. The one thing to understand before you start is that Fidelity's most-marketed products are the ones you can't take with you if you ever leave.
What does a Fidelity account actually cost?
Nothing to open, nothing to hold, and nothing to trade — for the things a beginner does. Fidelity charges no account minimums and no account fees on retail brokerage accounts, and $0 commission on online US stock and ETF trades. Its four ZERO index mutual funds carry a 0% expense ratio with no investment minimum.
| What you might do | What Fidelity charges |
|---|---|
| Open a brokerage account or IRA | $0, no minimum |
| Hold the account | $0 |
| Buy or sell a US stock online | $0 commission |
| Buy or sell an ETF online | $0 commission |
| Buy a Fidelity ZERO index fund | $0 commission, 0% expense ratio |
| Trade an option | $0 commission + $0.65 per contract |
The catch: the ZERO funds are a one-way door
Here's the part the comparison articles skip. Fidelity's ZERO funds — the 0% expense ratio ones that make the headlines — are available only to investors buying through a Fidelity brokerage account. They track Fidelity's own proprietary indexes rather than the industry-standard ones.
The practical consequence: no other brokerage can hold them. If you ever want to move your account elsewhere, a normal transfer moves your holdings across as they are. ZERO funds can't make that trip. You have to sell first — and in a taxable account, selling means realising whatever gains you've accumulated, on Fidelity's timetable rather than yours.
What the 0% expense ratio is actually worth
Put a number on what you're locking yourself in for. A mainstream total-market index fund charges roughly 0.03% a year. Fidelity's ZERO version charges nothing. Here's the annual difference:
| Balance | At ~0.03% | At 0% | You save per year |
|---|---|---|---|
| $1,000 | $0.30 | $0 | $0.30 |
| $5,000 | $1.50 | $0 | $1.50 |
| $25,000 | $7.50 | $0 | $7.50 |
| $100,000 | $30 | $0 | $30 |
| $250,000 | $75 | $0 | $75 |
This is not an argument against Fidelity. It's an argument for what to hold inside Fidelity. Buy a standard, portable index ETF and you get all of Fidelity's genuine strengths — the zero commissions, the no minimums, the excellent account handling — with none of the lock-in, and you give up an amount of money that rounds to nothing at beginner balances.
Where Fidelity is genuinely good
- No minimums, anywhere. You can open the account and buy a fractional share of an index fund with whatever you have. That removes the most common reason people never start — see how to start investing with $100.
- It's a broker, not a product. Fidelity holds whatever you want to hold. You aren't confined to a house portfolio, and you're not paying an advisory fee for a robot to rebalance you.
- The boring stuff works. Account transfers, beneficiary settings, tax documents, IRA conversions, a real phone number — the infrastructure that only matters on the day it matters.
- It scales with you. The account you open as a beginner is the same account that handles a rollover, a taxable account and a retirement withdrawal twenty years later. No migration required.
Where it's weaker
- Nobody tells you what to buy. A brokerage account is an empty container. If the prospect of choosing a fund is what's stopping you, the container doesn't solve it — a target-date fund or a robo-advisor might. Compare in robo-advisor vs. index funds.
- The interface assumes you know the vocabulary. "Core position," "settlement," "cost basis method" all appear before you've bought anything.
- The ZERO funds are marketed harder than they deserve. A 0% expense ratio is a superb headline and a marginal financial benefit at ordinary balances.
- Options cost $0.65 a contract. Irrelevant to a beginner buying index funds, and worth knowing if that's where you're heading. It usually shouldn't be — see 7 beginner investing mistakes.
A worked example: Tomas's first year
Tomas has $3,000 and $200 a month to invest, and he wants a Roth IRA.
Month 1. He opens a Roth IRA at Fidelity. Cost: $0. Minimum: none. He funds it with $3,000.
Month 1, the actual decision. He can buy a Fidelity ZERO total market fund at 0% or a standard total market ETF at about 0.03%. On $3,000 the difference is 90 cents a year. Because this is a Roth IRA, selling later triggers no tax bill, so the lock-in risk is small — he picks the ZERO fund and moves on. In a taxable account he'd pick the portable ETF for the same 90 cents.
Months 2–12. He adds $200 a month. Commission on each purchase: $0. By month 12 he has contributed $5,200. His total fees paid to Fidelity for the year: $0.
The comparison that matters. A robo-advisor at 0.25% would have charged him roughly $13 on that balance and chosen the portfolio for him. Neither number is large. The honest question isn't cost — it's whether Tomas will actually pick a fund on his own, or whether he'll open the empty account and freeze. If it's the second, $13 is cheap. How to buy your first index fund is the step he can't skip.
Common mistakes
- Funding the account and never buying anything. Uninvested cash sits in a core position earning whatever it earns — it is not invested. This is the single most common beginner error at any brokerage.
- Buying a ZERO fund in a taxable account without knowing about the exit. Fine if you never leave. Expensive if you do.
- Opening a taxable brokerage account before maxing a Roth. Usually backwards for a beginner — brokerage account vs. Roth IRA covers the order.
- Confusing the app's activity with progress. Watching a balance daily changes nothing except your blood pressure. What is dollar-cost averaging is the behaviour that does work.
- Investing while carrying card debt. A guaranteed return equal to your card's rate beats an uncertain one: pay off debt or invest first.
Edge cases
You have an irregular income. No minimums and no commissions make Fidelity unusually forgiving here — you can invest $60 one month and $0 the next without penalty. Set a percentage of each payment rather than a fixed monthly amount.
Your budget is tight. Don't invest money you'll need back within a couple of years, whatever the fee structure. Emergency savings first: sinking fund vs. emergency fund.
You're starting from literally zero knowledge. The account is the easy half. If choosing a fund feels like the hard half, a target-date fund inside the same account solves it in one purchase — are target-date funds worth it.
You already have investments elsewhere. Transfers in are generally straightforward. Check what you hold at the old brokerage for the same portability question in reverse, and ask both firms about any transfer-out fee before you start.
Who should skip Fidelity
Skip it if what you actually want is someone else to choose and rebalance the portfolio — that's a robo-advisor's job, and paying for it is reasonable. Skip it if an empty account with a search box is going to leave you paralysed for six months; a one-fund solution elsewhere that you actually buy beats a perfect account you never use. And skip any investing account for now if you're carrying revolving credit card debt or have no emergency savings.
For everyone else — a beginner who intends to buy a broad index fund, contribute regularly and not touch it — the cost of using Fidelity is genuinely, verifiably zero, and the only decision that needs care is which fund goes inside it.
Quick answers
Does Fidelity charge fees for a beginner account? No. Retail brokerage accounts and IRAs have no account minimums and no account fees, and online US stock and ETF trades carry $0 commission. Funds you buy charge their own expense ratios, which come out of the fund rather than your account, and options trades carry a $0.65 per-contract fee.
What's the catch with Fidelity's 0% expense ratio ZERO funds? They're proprietary — available only through a Fidelity brokerage account and tracking Fidelity's own indexes. No other brokerage can hold them, so leaving Fidelity means selling rather than transferring. In a taxable account that realises your gains on someone else's schedule; inside an IRA or Roth it isn't a taxable event.
Is Fidelity good for someone with only $100 to invest? Yes, in the sense that nothing about the account blocks you: no minimum to open, no commission to buy, and fractional shares mean $100 buys a slice of a broad index fund. Whether $100 is the right starting move depends on your emergency savings and any high-interest debt, not on the brokerage.
Is Fidelity better than a robo-advisor for beginners? Cheaper, yes — a robo typically charges around 0.25% a year and Fidelity charges nothing for the same account. Easier, not necessarily. A robo picks and rebalances the portfolio; Fidelity hands you an empty account. The right answer depends on whether you'll make the fund choice yourself.
Can I lose money in a Fidelity account? Yes. Fidelity holds and executes; it doesn't protect you from market falls. Any fund, ETF or stock you buy can lose value. Brokerage insurance covers the failure of the broker, not the performance of your investments.
