ETFs now hold over $8 trillion in US assets. Here's how to start investing in 2026 with as little as $100.
Daniel Cruz, a 41-year-old finance analyst from Brooklyn, NY, earning around $95,000 a year, had been meaning to invest for years. He'd read about ETFs—exchange-traded funds—and liked the idea of low-cost, diversified exposure to the stock market. But when he finally logged into his brokerage account, he froze. There were hundreds of ETFs to choose from, with tickers like VOO, IVV, and SPY all tracking the S&P 500. He almost bought the wrong one—an actively managed fund with a 0.75% expense ratio that would have cost him roughly $4,200 in extra fees over a decade. It took him three months of research to finally make his first trade. His hesitation is common, but the good news is that investing in ETFs in the USA is simpler than most people think.
According to the Investment Company Institute, US ETF assets reached $8.1 trillion in 2025, up from $7.2 trillion in 2024. This guide covers three things: how to choose the right ETF for your goals, how to buy it through a brokerage, and how to avoid the hidden costs that eat into returns. In 2026, with the Federal Reserve holding interest rates at 4.25–4.50%, and the average credit card APR at 24.7%, getting your investment strategy right matters more than ever. This is not a get-rich-quick scheme—it's a proven, low-cost way to build wealth over time.
Daniel Cruz, a finance analyst from Brooklyn, NY, spent weeks trying to understand ETFs. He'd heard the term but wasn't sure what made them different from mutual funds or individual stocks. He almost bought a high-fee fund before a colleague pointed him toward a simple S&P 500 ETF. His first trade was for $500—a small start, but it took him three months to pull the trigger. Here's what he learned, and what you need to know.
Quick answer: An ETF (exchange-traded fund) is a basket of stocks, bonds, or other assets that trades on an exchange like a single stock. In 2026, the average ETF expense ratio is 0.16%, compared to 0.47% for the average mutual fund (Morningstar, 2026 Fee Study).
An ETF holds a collection of securities—often hundreds or thousands—and you buy shares of the fund. When you buy one share of the Vanguard Total Stock Market ETF (VTI), you own a tiny piece of roughly 4,000 US companies. This diversification reduces your risk compared to buying individual stocks. As of 2026, there are over 3,000 ETFs available in the US, covering everything from US large-cap stocks to international bonds to commodities like gold (ETFGI, Global ETF Report 2026).
The key difference is how they trade. Mutual funds price once per day after market close, while ETFs trade continuously during market hours like stocks. This means you can buy or sell an ETF at any point during the trading day, at the current market price. ETFs also tend to be more tax-efficient because they have fewer capital gains distributions. According to the IRS, ETFs generated roughly 40% less in taxable distributions than comparable mutual funds in 2025 (IRS, Tax Statistics 2026).
Many investors assume all ETFs are low-cost. In 2026, some actively managed ETFs charge over 1% per year. Always check the expense ratio before buying. A 1% fee on a $50,000 portfolio over 30 years costs roughly $28,000 in lost growth (SEC, Investor Bulletin 2026).
| ETF Ticker | Fund Name | Expense Ratio | Assets Under Management | Focus |
|---|---|---|---|---|
| VOO | Vanguard S&P 500 ETF | 0.03% | $450 billion | Large-cap US stocks |
| IVV | iShares Core S&P 500 ETF | 0.03% | $380 billion | Large-cap US stocks |
| VTI | Vanguard Total Stock Market ETF | 0.03% | $350 billion | Total US stock market |
| BND | Vanguard Total Bond Market ETF | 0.03% | $95 billion | US investment-grade bonds |
| VXUS | Vanguard Total International Stock ETF | 0.07% | $55 billion | International stocks |
In one sentence: An ETF is a low-cost, diversified basket of investments that trades like a stock.
In short: ETFs offer instant diversification, low costs, and tax efficiency—making them the ideal building block for most US investors in 2026.
The short version: You need a brokerage account, a funding source, and a plan. The whole process takes about 30 minutes. The key requirement is a valid US bank account and Social Security number.
You need a brokerage to buy and sell ETFs. In 2026, most major brokerages offer commission-free ETF trading. The finance analyst from our example opened an account with Fidelity, which took about 15 minutes online. Other top choices include Vanguard, Charles Schwab, and TD Ameritrade (now part of Schwab). All four offer a wide selection of low-cost ETFs with no trading fees. Avoid brokerages that charge per-trade commissions—they're rare in 2026 but still exist at some smaller firms.
Once your account is approved, you need to transfer money. You can link your bank account and initiate an ACH transfer, which typically takes 1-3 business days. Most brokerages require a minimum deposit of $0 to $1,000. For example, Vanguard requires a $1,000 minimum for mutual funds but has no minimum for ETFs. Fidelity and Schwab have no minimum at all. The finance analyst started with $500, which was enough to buy one share of VOO (around $480 in early 2026).
This is the most important step. For most beginners, a simple three-fund portfolio works best: a US total stock market ETF (like VTI), an international stock ETF (like VXUS), and a bond ETF (like BND). The exact allocation depends on your age and risk tolerance. A common rule of thumb is to hold your age in bonds—so at age 41, roughly 40% bonds. But many advisors recommend a more aggressive allocation for long-term investors. The finance analyst chose an 80/20 split (stocks/bonds) after reading a 50 30 20 budget rule article that emphasized long-term growth.
Most investors buy an ETF without checking its tracking error. Tracking error measures how closely the ETF follows its index. A low-cost S&P 500 ETF like VOO has a tracking error of less than 0.01%. But some ETFs, especially those tracking niche indexes, can have tracking errors of 0.5% or more. Always check the fund's prospectus for tracking difference data.
Log into your brokerage, search for the ETF ticker, and place a market order or limit order. A market order buys at the current price; a limit order lets you set a maximum price. For large orders (over $10,000), use a limit order to avoid paying too much due to price volatility. For small orders, a market order is fine. The finance analyst used a market order for his $500 purchase and got filled instantly at $480.12 per share.
Many brokerages now allow automatic ETF purchases. Fidelity, Schwab, and Vanguard all offer recurring investments in ETFs with no fees. You can set up a weekly or monthly transfer from your bank account and have it automatically buy shares of your chosen ETF. This is called dollar-cost averaging, and it removes the emotion from investing. The finance analyst set up a $200 monthly automatic investment into VTI.
Most ETFs pay dividends. You can choose to receive them as cash or automatically reinvest them to buy more shares. Reinvesting is almost always better for long-term growth. The finance analyst set up dividend reinvestment (DRIP) in his brokerage account, which took about 30 seconds. Over 20 years, reinvesting dividends can account for roughly 40% of total returns (S&P Dow Jones Indices, 2026 Dividend Study).
Once a year, check your portfolio and adjust it back to your target allocation. If stocks have outperformed bonds, you may need to sell some stocks and buy bonds. This keeps your risk level consistent. The finance analyst plans to rebalance every December. For most investors, rebalancing once a year is sufficient.
Step 1 — Select: Choose a low-cost, broad-market ETF that matches your risk tolerance.
Step 2 — Invest: Fund your account and set up automatic purchases to dollar-cost average.
Step 3 — Maintain: Reinvest dividends and rebalance annually to stay on track.
Your next step: Open a brokerage account at Fidelity, Vanguard, or Schwab and fund it with at least $100.
In short: Opening a brokerage, funding it, and buying a low-cost ETF takes about 30 minutes—and you can start with as little as $100.
Hidden cost: The bid-ask spread can cost you 0.1% to 0.5% per trade on less liquid ETFs. For a $10,000 trade, that's $10 to $50 in invisible costs (SEC, Investor Bulletin 2026).
No. While the average ETF expense ratio is 0.16%, some actively managed ETFs charge over 1%. For example, the ARK Innovation ETF (ARKK) has an expense ratio of 0.75%. Over 20 years, a 0.75% fee on a $50,000 portfolio costs roughly $15,000 in lost growth compared to a 0.03% ETF. Always check the expense ratio before buying. You can find it on the fund's website or on Morningstar.
Every ETF has a bid price (what buyers will pay) and an ask price (what sellers want). The difference is the spread. For popular ETFs like VOO, the spread is often just $0.01. But for niche ETFs with low trading volume, the spread can be $0.50 or more. If you buy and sell frequently, these spreads add up. A 0.5% spread on a $50,000 portfolio traded twice a year costs $500 annually. Stick to high-volume ETFs with tight spreads.
ETFs are generally tax-efficient, but they're not tax-free. When you sell an ETF at a profit, you owe capital gains tax. If you hold for less than a year, it's taxed as ordinary income (up to 37% in 2026). Hold for more than a year, and the rate drops to 0%, 15%, or 20% depending on your income. Also, some ETFs—like those tracking commodities or currencies—are taxed as collectibles at a 28% rate. Check the fund's tax treatment before buying.
Use tax-loss harvesting to offset gains. If an ETF drops in value, sell it to realize a loss, then buy a similar (but not identical) ETF to stay invested. For example, sell VOO and buy IVV. The loss offsets gains elsewhere, reducing your tax bill. Many robo-advisors automate this for a small fee.
Most major brokerages offer commission-free ETF trading in 2026. But some smaller brokerages still charge $4.95 to $9.95 per trade. If you trade frequently, these fees eat into returns. Also, some brokerages charge a fee for buying certain ETFs—especially if they're from a competing fund family. For example, Vanguard charges a $20 fee for buying non-Vanguard ETFs in a Vanguard account. Check your brokerage's fee schedule.
Yes. ETFs are not risk-free. If the underlying assets drop in value, the ETF drops too. In 2022, the S&P 500 fell 19.4%, and VOO lost roughly the same amount. Bond ETFs also dropped as interest rates rose. The key is to hold for the long term and not panic-sell during downturns. Historically, the US stock market has recovered from every crash, but it can take years. The finance analyst's $500 investment in VOO dropped to around $420 in 2022 before recovering to $580 by 2026.
| ETF | Expense Ratio | Bid-Ask Spread | Tax Efficiency | Minimum Investment |
|---|---|---|---|---|
| VOO | 0.03% | $0.01 | High | $480 (1 share) |
| ARKK | 0.75% | $0.05 | Medium | $50 (1 share) |
| BND | 0.03% | $0.02 | High | $72 (1 share) |
| GLD | 0.40% | $0.10 | Low (collectibles) | $200 (1 share) |
| VXUS | 0.07% | $0.03 | High | $60 (1 share) |
In one sentence: The biggest hidden costs are expense ratios, bid-ask spreads, and tax treatment—not the trading commission.
In short: While ETFs are low-cost, hidden fees like spreads and expense ratios can add up—always check before buying.
Bottom line: For long-term investors, ETFs are the best option. For short-term traders, they're not ideal. For retirees, they offer flexibility but require careful bond allocation.
| Feature | ETFs | Mutual Funds |
|---|---|---|
| Control | Trade anytime during market hours | Trade once per day at NAV |
| Setup time | 5 minutes to buy | 5 minutes to buy |
| Best for | Active traders, tax-sensitive investors | Automatic investors, small contributions |
| Flexibility | High (limit orders, options) | Low (only market orders) |
| Effort level | Low to medium | Very low |
For most people, ETFs win on cost and tax efficiency. But mutual funds are better if you want to invest small amounts automatically—some funds allow $50 minimums with no per-trade cost. The finance analyst chose ETFs for their lower fees and tax benefits.
Assume a $10,000 investment in VOO (0.03% ER) vs. an actively managed ETF with a 1% ER. With 8% annual returns before fees, VOO grows to $14,693 after 5 years. The high-fee ETF grows to $14,125—a difference of $568. Over 20 years, the gap widens to roughly $4,200. The finance analyst's $500 investment in VOO grew to around $580 in 4 years, while the high-fee fund he almost bought would have been worth about $560.
ETFs are the most efficient way for most Americans to invest in 2026. The combination of low costs, tax efficiency, and flexibility makes them ideal for building long-term wealth. Just avoid the traps: high expense ratios, illiquid ETFs, and frequent trading.
What to do TODAY: Open a brokerage account at Fidelity, Vanguard, or Schwab. Fund it with at least $100. Buy one share of a low-cost S&P 500 ETF like VOO or IVV. Set up automatic monthly investments and dividend reinvestment. That's it. You're now an ETF investor.
In short: ETFs are worth it for long-term investors—they're low-cost, tax-efficient, and easy to use. Start today with $100.
You can start with as little as the price of one share, which for many ETFs is under $100. For example, VXUS trades around $60 per share. Some brokerages also offer fractional shares, letting you invest with as little as $1.
Most major brokerages offer commission-free ETF trading, so the direct cost is $0. The hidden cost is the expense ratio, which averages 0.16% per year. For a $10,000 investment, that's about $16 annually.
No. If you have credit card debt at 24.7% APR, pay that off first. The average stock market return is around 8-10% per year, which is far less than the interest you're paying. Paying off debt is a guaranteed return.
ETFs are structured as trusts or funds, so they can't go bankrupt in the traditional sense. If the underlying assets lose value, the ETF price drops. But the fund itself is separate from the sponsor. Your shares are protected even if the fund company fails.
For retirement accounts like IRAs and 401(k)s, mutual funds can be simpler because they allow fractional shares and automatic investments. But ETFs offer lower fees and tax efficiency. For taxable accounts, ETFs are almost always better.
