Open a Fidelity or Charles Schwab account, buy one low-cost index fund like FZROX or VTI, and turn on automatic monthly deposits. That's the whole answer for 90% of new investors. The rest of this is which platform fits your situation and why a few popular apps quietly cost you more than they advertise.

Here's the thing most "best broker" lists skip. The $0 commission everybody brags about isn't where these companies make money anymore. Robinhood and Webull earn from payment for order flow, cash sweeps, and margin lending. That doesn't make them bad. It means "free" deserves a second look.

What actually matters when you're starting out

Three things. Fees you can see (expense ratios, account minimums), fees you can't (order-flow spreads, idle-cash interest), and whether the app nudges you toward smart habits or risky ones.

Fidelity wins on the boring stuff that compounds. Its ZERO index funds (FZROX, FNILX) carry a 0.00% expense ratio, and uninvested cash earns roughly 4% automatically through its money market sweep. Robinhood pays far less on idle cash unless you pay $5 a month for Gold. Over ten years on a $20,000 balance, that gap alone is real money.

If you want hands-off, a robo-advisor builds and rebalances a portfolio for you. Betterment and Wealthfront both charge about 0.25% a year, so $25 annually per $10,000 invested. Cheap for automation. Still pricier than doing it yourself with a single target-date fund, which Vanguard offers for around 0.08%.

The platforms, side by side

| Platform | Best for | Account minimum | Notable cost | Standout feature | |---|---|---|---|---| | Fidelity | Most beginners | $0 | $0 funds available | 0.00% ZERO index funds, ~4% on cash | | Charles Schwab | Long-term buy-and-hold | $0 | Low expense ratios | Strong research, Schwab Intelligent Portfolios | | Vanguard | Index-fund purists | $0 | $0 ETF trades | Owns the funds it sells, fees keep dropping | | SoFi | Banking plus investing | $1 | $0 commissions | Auto-investing, fractional shares, one app | | Robinhood | Simple mobile trading | $0 | Order-flow spreads | Clean interface, IRA match up to 3% | | Betterment | Total hands-off | $0 | 0.25% advisory fee | Automatic rebalancing, tax-loss harvesting |

Schwab and Fidelity are close enough that you can't go wrong with either. Schwab's research tools run deeper, which matters more once you're past your first year. SoFi makes sense if you'd rather keep checking, savings, and investing under one login.

The trap to avoid

Counter-intuitively, the slickest app is often the worst place for a true beginner. Robinhood's confetti-and-swipe design (toned down after 2021 regulatory pressure) makes trading feel like a game, and gamier interfaces correlate with more frequent trading. More trades means worse returns for most people, not better. NerdWallet and academic studies on retail behavior both point the same direction: activity hurts.

You're not trying to be exciting. You're trying to buy broadly diversified funds and leave them alone for 20 years.

A realistic first month

Pick Fidelity or Schwab. Open a Roth IRA if you qualify (you can contribute up to $7,000 in 2025, or $8,000 if you're 50+), because tax-free growth beats a taxable account for most starters. Set up a $100 or $200 automatic transfer on payday. Buy a target-date fund or a total-market ETF. Don't check it daily.

If you want the mechanics spelled out before you click "buy," read our beginner's guide to investing first. Once you've got money in the market, our roundup of the best apps for tracking investments helps you watch performance without obsessing over it.

One honest caveat. This is educational information, not personalized advice. Your tax situation, debt, and emergency fund all come before investing, and a fee-only fiduciary can help if the numbers feel above your head.

My verdict after weighing fees, cash interest, and design: Fidelity for the widest beginner audience, Schwab if you'll grow into research tools, Betterment if you genuinely won't manage it yourself. Skip whichever app makes trading feel fun. Boring is the strategy that actually pays.

FAQ

Do I need a lot of money to start investing with Fidelity or Schwab? No. Both Fidelity and Charles Schwab require $0 to open a brokerage or Roth IRA account. Fidelity's FZROX and FNILX funds have no minimum purchase. Schwab's ETFs trade for one share at a time, typically under $100. You can realistically start with $50 to $100 per month and build from there using automatic recurring deposits.

Is Robinhood safe for a beginner investor? Robinhood is SIPC-insured up to $500,000 and regulated by FINRA, so your securities are protected against broker insolvency. The safety concern isn't custody. It's behavioral. Robinhood's mobile-first design, push notifications, and options-trading prominence statistically lead new users to trade more often, which reduces returns. For buy-and-hold index investing, Fidelity or Schwab is the less risky choice.

What is a Roth IRA and who qualifies in 2025? A Roth IRA is a retirement account where contributions are made with after-tax dollars, and all growth and withdrawals in retirement are tax-free. In 2025 you can contribute up to $7,000 per year ($8,000 if you're 50 or older). You must have earned income, and the full contribution phases out for single filers earning above $150,000 and joint filers above $236,000.

How much does Betterment's 0.25% fee actually cost over time? On a $10,000 balance, 0.25% is $25 per year. On $50,000 it's $125 annually. Over 20 years at 7% average returns, that fee drag reduces a $50,000 portfolio by roughly $8,000 to $10,000 compared to a self-managed Vanguard ETF at 0.03%. The fee is worth it if you genuinely would not invest otherwise. If you can handle one annual rebalance yourself, DIY wins on math.

Can I have both a Roth IRA and a regular brokerage account at the same time? Yes. Many investors use both. The Roth IRA gives you tax-free growth for retirement assets up to the annual limit. A taxable brokerage account has no contribution cap and no withdrawal restrictions, making it useful for goals before age 59.5, like a house down payment in five years. Fidelity and Schwab let you hold both account types under one login with the same set of funds.
