You need a brokerage account, money to invest, and a decision about which ETFs to buy

Investing in an ETF starts with opening an account at a brokerage firm — the company that holds your money and executes your trades. You then deposit cash, search for the ETF by its ticker symbol, and place a buy order just as you would for a single stock. The whole process takes minutes once your account is funded, though the account itself takes one to three business days to open.

The main decision is not how to invest, but where. Different brokerages charge different fees, offer different research tools, and have different minimum deposit requirements. Some charge per trade; others charge nothing. Some require $1,000 to start; others have no minimum. The ETF itself — the fund you are buying — costs the same no matter which brokerage you use, but the brokerage's fees can add up over time.

Key Takeaways

  • You must open a brokerage account before you can buy any ETF, and this account is separate from a bank account.
  • Most brokerages now charge zero commission per trade, but some still charge annual account fees or require minimum deposits.
  • Once your account is funded, buying an ETF takes the same steps as buying a stock: search by ticker, enter the number of shares, and confirm the order.
  • ETFs trade during market hours only, so an order placed after 4 p.m. Eastern Time will not execute until the next trading day.
  • You can hold ETFs in a regular taxable account or in a tax-advantaged account like an IRA, and the tax treatment differs between them.

Choose a brokerage and open an account

A brokerage is a licensed company that lets you buy and sell investments. Common brokerages include Fidelity, Charles Schwab, E*TRADE, TD Ameritrade, and Robinhood, but there are dozens of others. Each one has its own website and mobile app where you create an account, verify your identity, and link a bank account to deposit money.

When comparing brokerages, look at three things: commission per trade (many now charge zero), annual account fees (some waive these if you maintain a minimum balance), and minimum deposit to open the account. Read the fee schedule on their website — it is usually under "Pricing" or "Fees." Some brokerages also offer educational resources or research tools that may matter to you, but these are secondary to cost.

Opening an account requires your Social Security number, date of birth, address, and employment information. The brokerage will verify this against government records. The account is usually approved within one business day, though funding can take an additional one to three days if you are transferring money from a bank.

Deposit money into your brokerage account

Once your account is open, you must move money from your bank into the brokerage before you can buy anything. You do this by linking your bank account to the brokerage — the brokerage will ask for your bank's routing number and your account number, both of which appear on a check or in your bank's app.

Most brokerages offer two deposit methods: electronic transfer (ACH), which is free but takes three to five business days, and wire transfer, which is faster but costs $10 to $25. If you are in a hurry, wire transfer is quicker. If you can wait, ACH is free. Some brokerages also let you deposit by check, though this is slower and less common now.

The money sits in a cash account within your brokerage until you use it to buy an ETF. You can see this balance in your account dashboard at any time.

Find the ETF you want to buy by its ticker symbol

Every ETF has a ticker symbol — a short code like SPY, VOO, or QQQ. You search for this symbol in your brokerage's search bar, not the ETF's full name. The search will return the ETF's current price, its performance over different time periods, and its holdings (the stocks or bonds inside it).

If you do not know which ETF to buy, you can browse by category on your brokerage's website — most have sections for "stock ETFs," "bond ETFs," "sector ETFs," and so on. You can also search by what the ETF tracks: "S&P 500 ETF" will show you several options, each with a different ticker and slightly different fees.

Before you buy, check the ETF's expense ratio — the annual fee charged by the fund manager, expressed as a percentage of your investment. An expense ratio of 0.03% means you pay $3 per year for every $10,000 invested. This fee is deducted automatically and does not appear as a separate charge.

Place a buy order during market hours

Once you have found the ETF, click "Buy" or "Trade" in your brokerage app. You will be asked how many shares you want to purchase. If the ETF costs $100 per share and you have $5,000 to invest, you can buy 50 shares. The brokerage will show you the total cost before you confirm.

ETFs trade only during regular market hours: 9:30 a.m. to 4 p.m. Eastern Time, Monday through Friday. If you place an order after 4 p.m., it will not execute until the next trading day at the market open. Some brokerages offer after-hours trading, but this is less common and carries higher risk because fewer buyers and sellers are active.

When you confirm the order, the brokerage deducts the cost from your cash balance and adds the shares to your account. You will receive a confirmation email with the order details, including the exact price you paid per share and the total cost.

Understand the difference between taxable and tax-advantaged accounts

You can buy ETFs in a regular taxable brokerage account, or you can buy them inside a tax-advantaged account like a Traditional IRA, Roth IRA, or 401(k). The ETF itself works the same way in either account, but the tax treatment is different.

In a taxable account, you owe capital gains tax when you sell an ETF for more than you paid for it. You also owe tax on any dividends the ETF distributes. In a Roth IRA, you owe no tax on gains or dividends, ever — but you cannot withdraw the money before age 59½ without penalty. In a Traditional IRA, you do not owe tax on gains or dividends while the money is in the account, but you owe tax on the full amount when you withdraw it in retirement.

Most brokerages let you open both a taxable account and an IRA at the same time. If you are saving for retirement, an IRA is usually the better choice because of the tax benefits. If you are saving for something sooner, a taxable account is your only option.

Monitor your investment and rebalance if needed

After you buy an ETF, you can check its value any time by logging into your brokerage account. The price changes every trading day based on the value of the stocks or bonds inside the fund. You do not need to do anything — the ETF manager buys and sells holdings inside the fund automatically.

If you own multiple ETFs, you may want to rebalance once a year — selling some of the ETF that has grown the most and buying more of the one that has grown the least. This keeps your portfolio aligned with your original plan. Rebalancing is optional, but it can help you avoid taking on more risk than you intended.

You can sell an ETF at any time during market hours by clicking "Sell" in your brokerage app, entering the number of shares, and confirming. The money from the sale goes back into your cash balance, where you can withdraw it or use it to buy something else.

Frequently Asked Questions

Do I need a lot of money to start investing in ETFs?

No. Most brokerages have no minimum deposit, and since ETF shares trade like stocks, you can buy as few or as many shares as your budget allows. If an ETF costs $100 per share and you have $500, you can buy five shares. Some brokerages do require a minimum deposit to open the account, but this is usually $0 to $500.

What happens if I sell an ETF for less than I paid for it?

You take a loss on that investment. In a taxable account, you can use this loss to offset gains from other investments, which can reduce your tax bill. In a retirement account like an IRA, losses do not provide a tax benefit, but you can hold the investment longer and wait for it to recover.

Can I set up automatic investments in an ETF?

Yes. Most brokerages offer automatic investment plans where you specify an amount and a frequency — for example, $500 every month — and the brokerage buys the ETF on that schedule. This is called dollar-cost averaging and can reduce the impact of price swings over time.

What is the difference between buying an ETF and buying the stocks inside it?

An ETF holds many stocks or bonds in one fund, so you own a piece of all of them with a single purchase. Buying individual stocks means you own only those specific companies. ETFs are simpler and more diversified, but individual stocks can outperform if you pick the right ones.

Do I pay taxes on ETF dividends right away?

In a taxable account, yes — you owe tax on dividends in the year they are paid, even if you reinvest them. In a retirement account like an IRA or 401(k), you do not owe tax on dividends until you withdraw money from the account. This is one reason retirement accounts are tax-advantaged.
