Exchange-traded funds have become one of the easiest ways for beginners to start investing, but not all ETFs cost the same to hold. A fund’s expense ratio — the annual fee charged as a percentage of your investment — quietly eats into returns year after year. For a first-time investor, choosing low-cost ETFs is one of the simplest ways to keep more of what you earn.
Why Cost Matters More Than You Think
An expense ratio of 0.03% versus 0.75% might look like a tiny difference, but compounded over 20–30 years it can mean tens of thousands of dollars in lost returns on a long-term portfolio. Low-cost ETFs are not automatically better investments, but all else being equal, lower fees leave more money working for you.
What to Look for as a Beginner
- Expense ratio under 0.10% for core, broad-market funds
- High trading volume, which usually means tighter bid-ask spreads and easier buying and selling
- Broad diversification rather than a narrow sector or theme, especially for a first holding
- A long track record from an established fund provider
Common Categories of Low-Cost ETFs
Total Market and S&P 500 Funds
Broad U.S. stock market ETFs are often the cheapest category available, frequently charging 0.03% or less. They offer instant diversification across hundreds or thousands of companies in a single fund.
Total Bond Market Funds
For investors who want to balance stock exposure, low-cost bond ETFs provide income and reduce overall portfolio volatility, usually at a similarly low fee.
International Market Funds
Low-cost international ETFs let beginners add exposure outside their home market without needing to pick individual foreign stocks.
Mistakes Beginners Should Avoid
- Chasing a slightly cheaper fund that tracks a very different, less diversified index
- Ignoring trading costs and spreads on thinly traded ETFs, which can offset a low expense ratio
- Assuming “low-cost” always means “low-risk” — fees and risk are separate things
- Overlooking tax efficiency, which varies between fund structures
A Simple Starting Approach
Many beginners build a simple two- or three-fund portfolio: a broad U.S. stock ETF, an international stock ETF, and a bond ETF, each chosen for low fees and broad diversification. This keeps the portfolio easy to understand while minimizing the drag that high fees can cause over time.
Frequently Asked Questions
What counts as a “low-cost” ETF?
Many investors consider anything under 0.10% to be low-cost, with the cheapest broad-market funds often charging 0.03% or less.
Do low-cost ETFs perform worse than actively managed funds?
Not necessarily. Many actively managed funds charge higher fees and still fail to outperform low-cost index funds over long periods, though results vary by fund and time frame.
How much difference does a 0.5% fee really make?
Over several decades, even a 0.5% annual difference in fees can meaningfully reduce total returns due to the effect of compounding.
