The ETF industry launched 757 new funds in 2024, a 46% increase over the previous record [1]. There are now over 3,600 ETFs in the U.S. alone. The irony of an investment product designed to simplify your life is that choosing one has become genuinely complicated.
Leticia, a 34-year-old data analyst earning $78k, wanted to start investing and searched "best ETFs." She got 47 million results.
This article is the one that actually helps.
We've organized the best ETFs by goal, because "best" depends entirely on what you're trying to accomplish. A retiree looking for income needs a different ETF than a 25-year-old building wealth.
30-Second Summary: For most investors, a portfolio of 2 to 4 ETFs is enough. Start with a broad U.S. stock ETF (VOO or VTI), add international exposure (VXUS), and include bonds if you need stability (BND). Expense ratios matter enormously over time; the difference between 0.03% and 0.60% can cost you thousands on a modest portfolio over 20 years.
These are the foundation. One purchase, hundreds or thousands of stocks.
| ETF | Ticker | Expense Ratio | What It Tracks | 5-Year Annualized Return |
|---|---|---|---|---|
| Vanguard S&P 500 ETF | VOO | 0.03% | 500 largest U.S. companies | ~14% |
| Vanguard Total Stock Market ETF | VTI | 0.03% | Entire U.S. stock market (~3,600 stocks) | ~13% |
| iShares Core S&P 500 ETF | IVV | 0.03% | S&P 500 | ~14% |
| SPDR S&P 500 ETF Trust | SPY | 0.0945% | S&P 500 | ~14% |
VOO vs. VTI is the most common question in ETF investing. VOO tracks the S&P 500 (about 500 large-cap stocks representing ~80% of the U.S. market). VTI tracks the total U.S. stock market, including small and mid-cap companies. Historically, their returns are nearly identical because large caps dominate both. VTI gives you slightly more diversification. Either is excellent. For a deep dive, see our S&P 500 index fund guide.
SPY vs. VOO: SPY was the first S&P 500 ETF and has the highest trading volume of any ETF in existence. But its 0.0945% expense ratio is triple VOO's 0.03%. For buy-and-hold investors, VOO or IVV is the better deal. SPY's advantage is liquidity for active traders, which most people reading this article are not.
| ETF | Ticker | Expense Ratio | What It Tracks |
|---|---|---|---|
| Vanguard Total International Stock ETF | VXUS | 0.07% | ~8,000 stocks in developed and emerging markets |
| iShares Core MSCI Total International Stock ETF | IXUS | 0.07% | Similar global coverage |
| Vanguard FTSE Developed Markets ETF | VEA | 0.05% | Developed markets only (no emerging) |
The U.S. represents about 50% of the global stock market. Owning only U.S. stocks means ignoring half the world's companies. International diversification doesn't always boost returns, but it reduces the risk that your entire portfolio depends on one country's economy.
A common allocation is 60–70% U.S. and 30–40% international. If that feels too complicated, even 80/20 is better than 100/0.
| ETF | Ticker | Expense Ratio | 30-Day SEC Yield | What It Tracks |
|---|---|---|---|---|
| Vanguard Total Bond Market ETF | BND | 0.03% | 4.18% [2] | Entire U.S. investment-grade bond market |
| iShares Core U.S. Aggregate Bond ETF | AGG | 0.03% | ~4.1% | Similar to BND |
| Vanguard Short-Term Bond ETF | BSV | 0.04% | ~4.3% | Short-term bonds (less interest rate risk) |
Bonds reduce portfolio volatility. During stock market crashes, bonds often hold steady or rise. The trade-off: lower long-term returns. A 30-year-old building wealth might hold 10% bonds. A 60-year-old approaching retirement might hold 40%.
Yes, you can lose money in a bond ETF. BND dropped about 13% in 2022 when rates spiked. But bond ETFs still recover faster and with less drama than stock ETFs in most scenarios.
| ETF | Ticker | Expense Ratio | Focus | 5-Year Annualized Return |
|---|---|---|---|---|
| Vanguard Dividend Appreciation ETF | VIG | 0.06% | Dividend growers (10+ year streak) | 15.59% [3] |
| Schwab U.S. Dividend Equity ETF | SCHD | 0.06% | Quality dividend payers | ~13% |
| Vanguard High Dividend Yield ETF | VYM | 0.06% | High current yield | ~11% |
VIG focuses on companies that grow dividends consistently, even if current yield is modest. SCHD balances yield and quality. VYM tilts toward higher current income. For most investors under 50, VIG or SCHD is the better long-term pick because dividend growth compounds powerfully. Our article on dividend stocks explains the growth-vs-yield trade-off in detail.
Ryan, 28, invests $10,000 as a lump sum and adds nothing. Assumes 6% annual return. No additional contributions, just to isolate the fee impact.
| Fund Type | Expense Ratio | Value After 20 Years | Total Fees Paid |
|---|---|---|---|
| Low-cost ETF (VOO) | 0.03% | ~$31,895 | ~$190 |
| Average active fund | 0.60% | ~$28,629 | ~$3,460 |
| Difference | ~$3,266 |
Now scale that up. If Ryan contributes $500/month on top of his initial ten thousand dollars over those 20 years, the gap between 0.03% and 0.60% balloons to roughly $17,000 [4]. That's the price of a used car, paid in invisible fees.
That last point deserves emphasis. The financial industry profits from complexity. Your portfolio doesn't need to be complex to be effective.
If you own zero ETFs, start with VTI or VOO. One purchase, instant diversification into the entire U.S. market.
Audit your current holdings for expensive funds. Any mutual fund or ETF with an expense ratio above 0.20% deserves a second look.
Run the numbers. Use our compound interest calculator with your actual contribution amount and compare outcomes at 0.03% vs. your current fund's expense ratio.
