The best brokerage account depends on what you plan to trade, how often you trade, and what fees you can afford

There is no single "best" brokerage. A brokerage that works for someone buying index funds once a month will frustrate someone day-trading stocks. The account that suits a teenager opening their first investment will cost a professional trader money. Start by knowing what you actually do with your money — then match that to what each brokerage charges and allows.

The main things that differ between brokerages are commission per trade, account minimums, what you can buy (stocks, bonds, options, crypto, international), research tools, and customer support. Some brokerages are free to trade stocks but charge for options. Some have no minimums; others require $2,500 or more to open. Some let you buy fractional shares; others require whole shares only. The cheapest brokerage for you is the one whose fee structure matches what you actually buy.

Key Takeaways

  • Most major brokerages charge zero commission on stock and ETF trades, so the real cost difference is in account minimums, options fees, and margin interest rates.
  • If you plan to buy and hold index funds or individual stocks, a brokerage with no account minimum and fractional share support (like Fidelity, Schwab, or Vanguard) will cost you nothing per trade.
  • If you trade options or use margin, compare the per-contract fee and the margin interest rate, because these vary significantly and compound over time.
  • If you are under 18, opening an account requires a custodian, and not all brokerages offer custodial accounts at the same cost or with the same tools.
  • International investors should check whether a brokerage offers access to foreign exchanges and what currency conversion fees apply.

Zero-commission trading changed what you actually pay

In 2019 and 2020, most major brokerages dropped their per-trade commission to zero for stocks and exchange-traded funds (ETFs). This means you no longer pay $5 to $10 every time you buy or sell. That was the biggest cost for most retail traders, and it is now gone at Fidelity, Charles Schwab, E*TRADE, Interactive Brokers, TD Ameritrade, and Vanguard.

But zero commission does not mean zero cost. Brokerages still make money from you through account minimums, options contract fees, margin interest, currency conversion spreads, and inactivity fees. Some charge $0.50 to $1.00 per options contract. Some charge 6% to 12% annual interest if you borrow money to buy stock. Some charge 1% to 2% to convert dollars to euros. If you do none of these things, you pay nothing. If you do, these costs add up fast.

Account minimums and who they affect

An account minimum is the smallest amount of money you must deposit to open an account. Most major brokerages have dropped this to zero for regular brokerage accounts. Fidelity, Schwab, E*TRADE, and Interactive Brokers all allow you to open with $1. Vanguard requires $0 for most accounts but $50,000 for their advisory services.

Minimums matter more if you want a margin account (where you borrow money to buy stock) or if you want a managed account (where the brokerage invests your money for you). Margin accounts often require $2,000 to $25,000 depending on the brokerage. Managed accounts at Vanguard start at $50,000; at Fidelity, they start at $25,000. If you have less than that, you cannot use those services at that brokerage, so you need to pick a different one or wait until you have more money.

Options trading and contract fees

If you plan to trade options (contracts that give you the right to buy or sell a stock at a set price), the commission structure changes. Most brokerages charge $0 per options contract now, but some still charge $0.50 to $1.00 per contract. Over a year, if you trade options 50 times, that is $25 to $50 in fees. For a small account, that matters.

Brokerages also vary on which options strategies they allow. Some require you to pass a test and get approval before you can sell covered calls or buy puts. Some restrict options trading on certain accounts (like IRAs). If options are central to your plan, call the brokerage and ask what approval level you need and whether your account type supports it. Do not assume.

Margin interest rates and borrowing costs

If you use margin (borrowed money), you pay interest on the balance. The rate varies by brokerage and by how much you borrow. Interactive Brokers typically charges the lowest rates — often 2% to 4% depending on the size of your loan. Fidelity and Schwab charge 7% to 11%. E*TRADE charges 8% to 12%. Over a year, borrowing $10,000 at 10% costs you $1,000 in interest alone. If you plan to use margin, compare the rates before you open the account.

Margin is not assistance programs. You must repay it, and if the stock price drops, the brokerage can force you to sell to cover the loan. Only use margin if you understand the risk and have a plan to repay it.

What you can actually buy at each brokerage

Not all brokerages offer the same products. Most offer stocks, ETFs, and mutual funds. But access to options, bonds, futures, forex, and crypto varies. Fidelity and Interactive Brokers offer the widest range — stocks, options, bonds, futures, forex, and crypto all in one account. Vanguard focuses on stocks, ETFs, and mutual funds, with limited options support. Robinhood offers stocks, ETFs, options, and crypto but no bonds or futures.

If you want to buy individual bonds or trade futures, check the brokerage's product list before you open an account. Some brokerages also restrict what you can buy in certain account types. For example, you cannot trade options in a traditional IRA at most brokerages, but you can at others. Ask the brokerage directly if your plan requires a product they do not advertise.

Research tools and data access

Brokerages differ in what research and data they provide. Fidelity and Schwab offer extensive research, screeners, and educational content at no extra cost. Interactive Brokers offers powerful tools but assumes you know how to use them. Vanguard focuses on long-term investing and provides less day-trading-focused data. Robinhood offers minimal research tools.

If you plan to pick individual stocks, you will want a brokerage with a stock screener (a tool that filters stocks by price, earnings, dividend, or other metrics) and access to analyst reports. If you plan to buy index funds and hold them, research tools matter less. Think about how you actually invest, then check whether the brokerage's tools match that style.

Custodial accounts for minors

If you are under 18, you cannot open a brokerage account in your own name. A parent or guardian must open a custodial account (also called a UGMA or UTMA account, depending on your state). The adult controls the account until you turn 18 or 21, depending on state law.

Not all brokerages offer custodial accounts. Fidelity, Schwab, E*TRADE, and Vanguard all do. Robinhood does not. Custodial accounts at most brokerages have no account minimum and no fees, but some charge a small annual fee. Ask the brokerage whether they offer custodial accounts and what the cost is before you open one.

Frequently Asked Questions

Do I need to use the same brokerage for all my accounts?

No. You can open a regular brokerage account at Fidelity, an IRA at Vanguard, and a 529 college savings account at Schwab all at the same time. Some people do this to take advantage of each brokerage's strengths. However, managing multiple accounts means multiple logins and statements, so most people start with one brokerage and add others only if they need a specific product or feature.

What happens if a brokerage goes out of business?

Your money is protected by the Securities Investor Protection Corporation (SIPC), which covers up to $500,000 per account if a brokerage fails. This covers stocks, bonds, and cash but not crypto. Major brokerages like Fidelity, Schwab, and Vanguard are unlikely to fail, but SIPC protection exists if they do.

Can I move my money to a different brokerage later?

Yes. You can transfer your stocks and cash to another brokerage through a process called an ACAT transfer (Automated Customer Account Transfer). It usually takes 5 to 10 business days and is free. You do not have to sell your stocks to move them. However, some brokerages charge a fee to close your account, so check before you transfer.

Which brokerage is cheapest for someone who buys one index fund and holds it?

Fidelity, Schwab, and Vanguard all cost the same for this: zero. No account minimum, no commission, no fees. Pick whichever has the best interface for you or the best customer service. The cost difference is zero, so the decision comes down to usability and support.

Do I need to pay taxes on money I make in a brokerage account?

Yes. A regular brokerage account is taxable. You owe capital gains tax on profits when you sell, and dividend tax on dividends you receive. A tax-advantaged account like an IRA or 401(k) lets you defer or avoid these taxes. If you want to minimize taxes, open a retirement account first, then use a regular brokerage account for money you plan to spend before retirement.
