ZERO Index Funds: Investing With Literally No Fees
Fidelity is the only major brokerage that offers index funds with a true 0.00% expense ratio. That means every dollar you invest goes to work — nothing is skimmed off for management fees, ever. Here are the three ZERO funds:
| Ticker | Fund Name | Expense Ratio | What It Does |
|---|---|---|---|
| FZROX | Total Market | 0.00% | Owns the entire U.S. stock market — thousands of companies, one fund. |
| FNILX | Large Cap | 0.00% | Tracks the largest 500 U.S. companies — a free alternative to S&P 500 funds. |
| FZIPX | Extended Market | 0.00% | Mid- and small-cap companies — adds diversity beyond the big names. |

Why this matters: Over 30 years, the difference between a 0.00% and 0.05% expense ratio on a $500,000 portfolio is roughly $12,000 in saved fees. That's money that stays invested and compounds for you.
The HSA: Best Health Savings Account in the Industry
If you're eligible for a Health Savings Account, Fidelity's is the one to have. Most HSA providers charge monthly fees and limit you to a small menu of expensive funds. Fidelity charges nothing and gives you their full brokerage.
No monthly maintenance fees, no minimum balance to invest, and no trading commissions. Most competitors charge $2–$4/month.
Unlike most HSAs that limit you to 10–20 expensive mutual funds, Fidelity lets you buy any stock, ETF, or ZERO fund in your HSA. (Source: Fidelity HSA page)
HSAs are the only account type that's tax-free going in, tax-free growing, and tax-free coming out (when used for medical expenses). After age 65, it works like a traditional IRA for any purpose.
Cash Management Account: A Checking Account That Earns Interest
Fidelity's Cash Management Account works like a checking account but pays about 3.30% APY through their SPAXX money market fund. It comes with free checks, bill pay, and — here's the best part — unlimited ATM fee reimbursement worldwide. Use any ATM anywhere, and Fidelity refunds the fee automatically.
Good to know: The Cash Management Account also provides up to $4 million in FDIC coverage through a sweep program that distributes your cash across multiple partner banks. (Source: Fidelity CMA page)
No Payment for Order Flow (PFOF): What That Means for You
Many brokerages (like Robinhood and Webull) earn money by selling your trade data to high-frequency trading firms — a practice called "payment for order flow." Fidelity doesn't do this. Instead, they focus on "price improvement," which means they actively try to get you a better price than what's quoted on the market. Fidelity says this saved clients an average of $15 per bond trade in early 2026.
What We Like & What to Watch Out For
- True 0.00% index funds: FZROX, FNILX, and FZIPX charge absolutely nothing. No other brokerage offers this.
- Best HSA available: $0 fees, $0 minimums, and full brokerage access. Every other HSA provider falls short.
- No PFOF: Fidelity doesn't sell your trade data. They prioritize getting you the best price on every trade.
- 24/7 support with real humans: You can reach a person by phone in under 2 minutes. Most competitors have cut human support.
- High margin rates (~12.5%): If you borrow money to invest (margin trading), Fidelity is expensive compared to Interactive Brokers.
- Limited crypto: They offer Bitcoin and Ethereum, but the selection is small compared to dedicated crypto exchanges.
- Can feel overwhelming: Fidelity has so many tools and features that beginners may find the interface confusing at first. The app has improved significantly, but it's not as simple as SoFi or Wealthfront.
Our Bottom Line
Fidelity is our top pick for long-term investors. The zero-fee index funds, industry-best HSA, and commitment to transparent pricing make it the most trustworthy brokerage for building real, lasting wealth. If you're someone who plans to invest consistently for 10+ years, start here.
