VOO is the Vanguard S&P 500 ETF — a single fund that gives you ownership of roughly 500 of the largest U.S. companies for an annual cost of 0.03%. It trades on the NYSE Arca exchange under the ticker VOO, just like any stock. If you can buy a share of Apple, you can buy a share of VOO. Here's how, from zero to invested, in five steps.
If you want to understand what you're buying before you buy it, start with our complete guide to the Vanguard S&P 500 ETF. If you already know what VOO is and just want the mechanics, read on.
Step 1: Choose a Brokerage Account
You need a brokerage account to buy VOO. Every major U.S. broker offers commission-free ETF trading, so the choice comes down to features, interface, and account types. Here are the most popular options:
| Broker | Fractional Shares | Auto-Invest | Best For |
|---|---|---|---|
| Fidelity | Yes (min $1) | Yes | All-around best for most investors |
| Schwab | Yes (min $5) | Yes | Strong research tools and banking |
| Vanguard | No | Limited | Vanguard loyalists; buy-and-hold |
| Robinhood | Yes (min $1) | Yes | Simple mobile-first experience |
| Interactive Brokers | Yes | Yes | Advanced traders; international access |

Which broker should you pick? For most people, Fidelity or Schwab is the right choice. Both offer fractional shares (so you can invest any dollar amount), automatic recurring purchases, excellent mobile apps, and all the account types you'll need (taxable, Roth IRA, traditional IRA, HSA). Vanguard's platform is functional but dated; it doesn't support fractional ETF shares and its automatic investing features are limited to mutual funds like VFIAX.
If you already have a brokerage account, there's no need to open a new one. VOO is available on every platform. Skip to Step 3.
Step 2: Open and Fund Your Account
Opening a brokerage account takes about 10 minutes. You'll need your Social Security number, a government ID, and a bank account for funding. Most brokers verify your identity instantly.
Which account type? This is one of the most important decisions you'll make, and it depends on your goal:
Roth IRA — Best if you're investing for retirement and expect to be in a higher tax bracket later. Contributions go in after-tax, but all growth and dividends are tax-free forever. In 2026, you can contribute up to $7,000 per year ($8,000 if you're 50+), subject to income limits. For a deep dive on using VOO specifically in a Roth, see our VOO Roth IRA guide.
Traditional IRA — Contributions may be tax-deductible now, but withdrawals in retirement are taxed as ordinary income. Same contribution limits as a Roth.
Taxable brokerage account — No contribution limits, no withdrawal restrictions, but you'll owe taxes on dividends annually and capital gains when you sell. VOO is highly tax-efficient (it rarely distributes capital gains), which makes it one of the best ETFs for taxable accounts.
401(k) / 403(b) — If your employer plan offers a Vanguard S&P 500 index fund, you're effectively getting the same underlying portfolio as VOO. You typically can't buy ETFs directly in a 401(k), but the mutual fund equivalent works identically.
Once your account is open, transfer money from your bank. ACH transfers are free but take 1–3 business days. Some brokers let you trade immediately while the transfer settles.
Step 3: Search for VOO and Place Your Order
In your brokerage app or website, search for ticker VOO. You'll see the Vanguard S&P 500 ETF with its current price (around $582.96 as of this writing).
You have two main order types:
Market order — Buys immediately at the current best available price. This is the simplest option and is fine for most investors. VOO is so heavily traded (~14.5 million shares per day) that the spread between bid and ask is essentially zero. You'll get a fair price.
Limit order — Buys only if the price drops to a level you specify. For example, you could set a limit at $575 and the order would only fill if VOO drops to that price. This gives you price control but the order might not fill if the price doesn't reach your limit.
For a long-term investment that you plan to hold for years or decades, a market order during regular trading hours (9:30 AM – 4:00 PM ET) is perfectly fine. Don't overthink the entry price — whether you buy at $580 or $585 won't matter 20 years from now.
Fractional shares. If you want to invest a specific dollar amount (like $200/month) rather than buying whole shares, use your broker's fractional share or "dollar-based" trading feature. This lets you invest exactly the amount you want regardless of VOO's share price. Fidelity, Schwab, and Robinhood all support this.
Step 4: Set Up Automatic Investing
The most effective way to build wealth with VOO is to invest consistently on a schedule — the "VOO and chill" approach. Most brokers let you set up automatic recurring purchases: pick an amount, pick a frequency (weekly, biweekly, monthly), and the broker handles the rest.
Automatic investing removes the temptation to time the market. Research consistently shows that time in the market beats timing the market. A fixed recurring purchase also implements dollar-cost averaging by default: you buy more shares when prices are low and fewer when prices are high.
Even small amounts compound dramatically over time. Investing $500 per month in VOO with a 10% average annual return grows to approximately $1.13 million over 30 years. Try our retirement calculator to model your own scenario.
Step 5: Turn On Dividend Reinvestment (DRIP)
VOO pays quarterly dividends — currently about $1.87 per share per quarter. By default, most brokers deposit these as cash into your account. You should turn on DRIP (Dividend Reinvestment Plan) so that each dividend is automatically used to buy more VOO shares.
DRIP is free at every major broker and works with fractional shares. If you receive a $18.70 dividend (from 10 shares), DRIP automatically buys ~0.032 additional shares at the current price. Over decades, this reinvestment compounds significantly — it's free money buying you more free money.
To enable DRIP, look in your brokerage account's settings or the holdings detail page for a "Dividend Reinvestment" toggle. Most brokers also let you enable DRIP at the time of purchase. Our dividend income calculator lets you project how DRIP compounds your income over 5, 10, or 20 years.
VOO vs VFIAX: ETF or Mutual Fund?
Vanguard offers the same S&P 500 portfolio in two forms: VOO (the ETF) and VFIAX (the Admiral Shares mutual fund). They hold the same stocks, charge the same 0.03% expense ratio, and deliver the same returns. The differences are mechanical:
| Feature | VOO (ETF) | VFIAX (Mutual Fund) |
|---|---|---|
| Trading | Intraday, like a stock | Once daily at 4 PM ET |
| Minimum Investment | ~$1 (with fractional shares) | $3,000 at Vanguard |
| Auto-Invest | Broker-dependent | Yes, at Vanguard |
| Available At | Any broker | Vanguard only (for direct purchase) |
| Tax Efficiency | Slightly better (ETF mechanism) | Same (Vanguard share class) |
For most investors, VOO is the better choice because it has no minimum investment (with fractional shares), is available at every broker, and can be bought or sold at any point during the trading day. VFIAX makes sense if you already have a Vanguard account and prefer the simplicity of automatic mutual fund investing.
Common Mistakes to Avoid
Waiting for a dip. The most expensive mistake in investing is staying on the sidelines. The S&P 500 has recovered from every single downturn in its history and has delivered positive returns over every 20-year rolling period. Waiting for the "right time" to buy costs you more in missed gains than any dip would save you.
Trading too often. VOO is designed to be bought and held. Selling because the market dropped 5% and buying back when it recovers is a recipe for destroying returns. The VOO and chill strategy works because it eliminates emotional decision-making.
Ignoring account type. Buying VOO in a taxable account when you have unused Roth IRA contribution room is leaving tax-free growth on the table. Max out tax-advantaged accounts first, then invest additional money in taxable accounts.
Buying similar funds. If you hold VOO, you don't need SPY, IVV, or SPLG — they all track the same index. Owning multiple S&P 500 funds gives you zero additional diversification. See our VOO vs SPY comparison for why you should pick one and stick with it. If you want broader diversification beyond large-caps, consider VTI for total U.S. market exposure.
Skipping DRIP. Leaving dividends as uninvested cash is leaving compounding returns on the table. Always enable dividend reinvestment unless you specifically need the income for living expenses.
Buying VOO from Outside the U.S.
VOO is a U.S.-listed ETF. International investors face a few additional considerations: you may need a broker that provides access to U.S. markets (Interactive Brokers is the most common choice), you'll be subject to a 30% withholding tax on dividends (reducible under tax treaties), and currency conversion fees may apply. Some countries offer locally-listed equivalents (like VUSA in Europe) that are domiciled in Ireland with more favorable tax treatment. For a full breakdown, see our international investor guide.
What to Do After You Buy
Once you own VOO, the best thing to do is very little. Check your holdings quarterly at most. Don't watch the daily price — short-term volatility is noise. Focus on three things: keep contributing regularly, keep DRIP enabled, and rebalance your overall portfolio (stocks vs bonds) once a year if needed.
If you're worried about buying at the wrong time, remember that VOO is a bet on the 500 largest U.S. companies over the long term. The S&P 500 has delivered positive returns over every rolling 20-year period in its history, including periods that started right before major crashes like 2000 and 2008. The risk of VOO isn't that it goes down temporarily — it will. The risk is that you panic and sell during those temporary drops. The best protection against that risk is automating your contributions and not looking at your portfolio too often.

Frequently Asked Questions
If your broker supports fractional shares (Fidelity, Schwab, and most others do), you can buy VOO with as little as $1. If your broker requires whole shares, the minimum is the price of one share — currently around $582. There is no separate minimum investment imposed by Vanguard for the ETF.
Yes. VOO is available on Robinhood, Fidelity, Schwab, Vanguard, Interactive Brokers, and virtually every U.S. brokerage. All major brokers offer commission-free ETF trading, so there's no cost to buy or sell VOO regardless of which platform you use.
VOO (ETF) and VFIAX (mutual fund) hold the exact same stocks and charge the same 0.03% expense ratio. The main differences: VOO trades intraday like a stock and has no minimum investment (with fractional shares), while VFIAX trades once daily at market close and requires a $3,000 minimum at Vanguard. For most investors, VOO is more flexible.
A Roth IRA is generally the better choice if you're eligible, because all future growth and dividends are completely tax-free. In a taxable account, you'll owe taxes on VOO's quarterly dividends and on capital gains when you sell. That said, VOO is one of the most tax-efficient ETFs available, so it works well in taxable accounts too.
Historically, investing a lump sum immediately outperforms dollar-cost averaging about two-thirds of the time, because markets tend to rise over time. However, dollar-cost averaging (investing a fixed amount on a regular schedule) reduces the risk of buying at a peak and can be easier psychologically. If you have a lump sum and a long time horizon, investing it all at once has better expected returns. If you earn income regularly, setting up automatic recurring purchases is a practical and effective approach.
