You need a brokerage account, money to invest, and about 10 minutes to place your first trade

Investing in an ETF means buying shares of a fund that holds a basket of stocks, bonds, or other assets. You do this through a brokerage account — the same type of account you would use to buy individual stocks. Open an account with a broker, deposit money, search for the ETF by its ticker symbol, and place a buy order just like you would for any stock. The whole process takes minutes once your account is funded.

The main decision before you start is whether to use a regular taxable brokerage account or a tax-advantaged account like an IRA or 401(k). Most people new to investing should start with whichever account their employer offers first — usually a 401(k) match is assistance programs you should not leave on the table. After that, a regular brokerage account is simpler and has no contribution limits or withdrawal penalties.

Key Takeaways

  • You need a brokerage account with a broker like Fidelity, Vanguard, Charles Schwab, or a discount broker, and enough cash to buy at least one share of the ETF you want.
  • Most brokers charge no commission to buy or sell ETFs, though you will pay the small difference between the buy and sell price (the spread) when you trade.
  • Search for an ETF by its ticker symbol (a short code like SPY or VTI), review its holdings and expense ratio, then place a buy order during market hours.
  • A taxable brokerage account is the simplest starting point; tax-advantaged accounts like IRAs have contribution limits but offer tax benefits for long-term holding.
  • Your first purchase does not have to be large — many ETFs cost $50 to $200 per share, and you can start with one share or a few hundred dollars.

Choose a broker and open an account

A broker is a company that lets you buy and sell investments. The major brokers used by individual investors include Fidelity, Vanguard, Charles Schwab, E-Trade, and Merrill Edge. Smaller discount brokers like Webull, M1 Finance, and Alpaca also exist. All of them allow you to buy ETFs with no commission — meaning you do not pay a fee to place the trade itself.

Opening an account takes 10 to 15 minutes online. You will need your Social Security number, a government ID, proof of address, and your bank account details to link for deposits. The broker will ask you to confirm you understand the risks of investing and whether you want a taxable account or a retirement account. If you are unsure, start with a taxable brokerage account — it has no rules about when you can withdraw money or how much you can invest each year.

After you open the account, you will need to deposit money before you can buy anything. Most brokers let you link a checking or savings account and transfer money electronically. The transfer usually takes one to three business days to show up in your brokerage account.

Decide how much to invest and how often

There is no minimum investment to start — you can buy a single share of an ETF that costs $80 and own it. However, most people find it easier to think in dollar amounts. Decide whether you want to invest a lump sum (say, $1,000 or $5,000 all at once) or set up automatic monthly deposits (say, $200 every month). Both approaches work; automatic deposits are simpler if you are building a habit and do not have a large amount saved yet.

The cost of an ETF share varies widely. Some trade for $20 to $50 per share; others cost $200 or more. The price does not tell you whether an ETF is expensive or cheap — that is determined by the expense ratio, which is the annual fee the fund charges as a percentage of your money. A good expense ratio for a broad stock ETF is under 0.10% per year. A bond ETF might cost 0.05% to 0.15%. Specialty or actively managed ETFs can cost 0.50% or more.

Do not worry about timing the market perfectly. If you have money to invest, invest it. Trying to guess when the market will go up or down usually costs you money in the long run.

Find and research the ETF you want to buy

Every ETF has a ticker symbol — a short code of one to five letters. The S&P 500 ETF trades under the ticker SPY, IVV, or VOO depending on which fund you choose. The total U.S. stock market ETF trades under VTI or ITOT. Once you know which ETF you want, you can search for it by ticker in your broker's platform.

Before you buy, spend five minutes reviewing the fund's basics. Your broker's website will show you the expense ratio, the fund's holdings (what stocks or bonds it owns), and the fund's size (larger funds are usually more stable). You can also look up the ETF on the fund company's website — Vanguard, Fidelity, iShares, and Schwab all publish detailed fact sheets. Read the fund's objective to make sure it matches what you want to own. A fund labeled "large-cap growth" will behave very differently from one labeled "dividend-paying stocks" or "emerging markets bonds."

Check the trading volume — how many shares trade each day. ETFs with very low volume (fewer than 100,000 shares per day) can be harder to buy or sell without paying a wider spread. Most popular ETFs trade millions of shares daily and have tight spreads of just a penny or two.

Place your buy order during market hours

Once you have money in your account and have chosen an ETF, you are ready to buy. Log into your broker's platform and search for the ETF by its ticker symbol. Click "buy" or "trade," enter the number of shares you want (or the dollar amount, if your broker lets you), and review the order before you submit it.

You will see the current price of the ETF and the bid-ask spread — the difference between what buyers are willing to pay and what sellers are asking. For a popular ETF, this spread is usually just a few cents. Place your order during market hours (9:30 a.m. to 4 p.m. Eastern time on weekdays when the market is open). Your order will execute almost instantly at or near the price you see on screen.

After your trade settles (usually the next business day), the shares will appear in your account. You now own a piece of the ETF and will see its value change as the market moves. You do not have to do anything else — the ETF will hold its underlying investments for you automatically.

Understand costs and taxes

The main cost of owning an ETF is the expense ratio — the annual fee charged by the fund. This is deducted automatically from the fund's value each day, so you do not write a check. A 0.05% expense ratio on a $10,000 investment costs $5 per year. A 1% expense ratio on the same $10,000 costs $100 per year. Over decades, the difference between a cheap ETF and an expensive one can be tens of thousands of dollars.

You will also pay the bid-ask spread when you buy or sell — usually just a few cents per share on popular ETFs. This is not a fee to the broker; it is the difference between the buy and sell price, similar to how a currency exchange charges a spread. On a $5,000 trade, the spread might cost you $2 to $5.

If you hold the ETF in a taxable brokerage account, you will owe taxes on any gains when you sell, and you may owe taxes on dividends the ETF pays each year. If you hold the ETF in an IRA or 401(k), you do not pay taxes on gains or dividends until you withdraw the money in retirement. This is why tax-advantaged accounts are powerful for long-term investing.

Set up a plan and stick to it

The hardest part of investing is not picking the right ETF — it is staying invested when the market drops. Markets fall 10% to 20% regularly and 30% or more occasionally. If you panic and sell during a drop, you lock in losses. If you stay invested, you usually recover and go on to new highs.

The best defense against panic is a plan. Decide in advance how much you will invest, how often, and what you are investing for (retirement in 30 years, a house down payment in 5 years, etc.). Write it down. When the market drops 20% and you feel scared, look at your plan and remember that you expected this. If you are investing for 30 years, a market drop is actually good — it means you can buy more shares at lower prices.

Most people benefit from setting up automatic monthly investments and then ignoring the account for months at a time. Checking your balance every day or every week leads to emotional decisions. Checking it once or twice a year keeps you on track without the noise.

Frequently Asked Questions

Can I buy an ETF with just $100?

Yes. If an ETF costs $50 per share, $100 buys you two shares. If it costs $200 per share, $100 buys you half a share (most brokers allow fractional shares). Start with whatever amount you have; the size of your first purchase does not matter as much as starting and staying consistent.

Do I have to buy a whole number of shares?

Most brokers now allow fractional shares, so you can buy $100 worth of an ETF that costs $150 per share and own 0.67 shares. A few older brokers still require whole shares, but this is becoming rare. Check your broker's website or ask before you open an account if fractional shares matter to you.

What is the difference between buying an ETF and a mutual fund?

ETFs trade like stocks during market hours and usually have lower expense ratios. Mutual funds are priced once per day after the market closes and often have higher fees. For most new investors, ETFs are the simpler and cheaper choice. Both hold baskets of investments, so the core idea is the same.

Should I buy the same ETF every month or switch between different ones?

Pick one or two broad ETFs that match your goals and buy them consistently. Switching between ETFs often leads to worse results because you are trying to time the market. A simple approach — buying the same low-cost stock market ETF every month for 30 years — beats most people who trade frequently.

What happens if the brokerage company goes out of business?

Your investments are protected by the Securities Investor Protection Corporation (SIPC), which covers up to $500,000 per account at a failed broker. This means even if your broker fails, you get your shares back or the cash value. Use a well-known broker and you will not face this risk in practice.
