How to Buy Your First ETF: Complete Walkthrough
The exact steps to go from 'I have a brokerage account' to 'I own my first ETF shares' in under 10 minutes.
Don't have time? Here's what you need to know:
- 1Search the ticker (VOO or VTI), click Buy, choose a market order, enter your amount — done in 2 minutes
- 2Set up automatic recurring purchases immediately after your first buy
- 3Enable dividend reinvestment (DRIP) so your dividends compound automatically
- 4Do not worry about timing your first purchase — monthly consistency matters far more
Step 1: Search for the ETF by Ticker
Log into your brokerage account and find the trade or search bar. Type the ticker symbol of the ETF you want to buy. For your first ETF, VOO (Vanguard S&P 500) or VTI (Vanguard Total Stock Market) are the most common starting points. You will see the current price, the day's change, and basic fund information.
Before buying, confirm three things: the expense ratio (should be under 0.10% for a core index fund), the fund size (larger is generally better — VOO has over $400 billion in assets), and what index it tracks. For VOO, you are buying the S&P 500. For VTI, you are buying the total U.S. stock market.
Step 2: Place Your Order
Click 'Buy' and choose your order type. For a liquid ETF like VOO or VTI, a market order is fine — it executes instantly at the current price. The bid-ask spread on these funds is typically one cent. Enter the dollar amount (if your broker supports fractional shares) or the number of shares you want to buy.
If buying during market hours (9:30 AM - 4:00 PM ET), your order fills in seconds. If you place an order after hours, it executes when the market opens the next day at whatever price is available. For your first purchase, placing the order during market hours keeps things simple.
Tip: Buying $200 worth of VOO every month on the 15th is a better strategy than trying to find the perfect entry point. Set it up once and forget about it.
Step 3: Automate Future Purchases
The single most valuable thing you can do after your first purchase is set up automatic recurring investments. Fidelity, Schwab, and Vanguard all let you schedule automatic ETF purchases on a weekly, bi-weekly, or monthly basis. Pick an amount, pick a date, pick your ETF, and the broker handles the rest.
This is dollar-cost averaging on autopilot. When prices are high, your fixed dollar amount buys fewer shares. When prices drop, you automatically buy more shares at a discount. Over time, this smooths out your average purchase price and removes the temptation to time the market.
- Fidelity: Automatic investments available for ETFs and mutual funds, no minimum
- Schwab: Automatic investing with Schwab Intelligent Portfolios or manual scheduling
- Vanguard: Automatic investments for Vanguard mutual funds; ETFs require manual buys or a workaround through their brokerage
- Robinhood: Recurring investments available on daily, weekly, or monthly schedules

Step 4: Enable Dividend Reinvestment
VOO and VTI pay dividends quarterly. By default, those dividends land as cash in your account. Turn on DRIP (Dividend Reinvestment Plan) and those dividends automatically buy more shares instead. On a $10,000 investment in VOO yielding about 1.3%, that is roughly $130 per year being reinvested — which compounds on top of your regular contributions.
In a taxable account, you still owe taxes on reinvested dividends even though you never received the cash. In a Roth IRA, dividends grow completely tax-free. Either way, reinvesting dividends is almost always the right move for long-term investors.
Frequently Asked Questions
What if I buy at the wrong time and the price drops?
This will happen — and it does not matter long-term. If you invest monthly for 20+ years, your early purchases represent a tiny fraction of your total contributions. A 10% drop after your first $200 purchase means you lost $20. Your next monthly purchase buys shares 10% cheaper. Over time, the average price you pay smooths out.
Should I buy one share or use fractional shares?
Use fractional shares if your broker offers them. Investing $100 worth of VOO is better than waiting months to save up $500+ for a full share. The sooner your money is invested, the sooner it starts compounding. Fractional shares work identically to full shares for returns and dividends.
How do I know if my order went through?
Your broker shows an order confirmation immediately after execution. Check your 'Positions' or 'Holdings' tab — you should see the ETF with the number of shares (or fractional shares) you bought, the average cost per share, and the current market value. You will also receive a confirmation email.
