More than $7 trillion sits in ETFs in the U.S., while mutual funds still hold over $22 trillion. Both products dominate American retirement accounts, but they work in different ways.
The choice between ETF or mutual fund often confuses new investors. Both can hold the same stocks. Both come in low-cost index versions. The differences lie in how they trade, how they are taxed, and what minimums they require.
This guide breaks down the ETF vs mutual fund debate in plain language. If you are also working on your credit score, a credit builder card can fit alongside your investing plan.
ETF or Mutual Fund: The Basics
An ETF, or exchange-traded fund, trades on a stock exchange like a regular stock. Prices update throughout the day.
A mutual fund pools money from many investors. The fund's price, called the net asset value, updates once per day after the market closes.
Both can be active or passive. A passive fund tracks an index. An active fund tries to beat the market through stock picking.
For most beginners, low-cost passive options work well in either format. If you are still weighing whether to deploy cash at all, our guide on saving vs investing lays out the trade-offs.
ETF vs Mutual Fund: Trading
This is one of the biggest differences.
ETFs Trade Intraday
ETFs can be bought or sold any time the market is open. Prices change second by second. You can use limit orders, stop orders, and other tools just like stocks.
Mutual Funds Settle Once Per Day
Mutual fund orders all execute at the closing price. It does not matter when you placed the order during the day. You get the 4 p.m. ET price.
For long-term investors, this difference rarely matters. For active traders, intraday flexibility is one reason to choose ETFs.
Fees and Expense Ratios
Both fund types charge an expense ratio. This is the yearly fee taken from fund assets.
ETFs tend to charge lower expense ratios on average. Many top ETFs charge 0.03% to 0.10%. Some mutual funds match these low fees, especially index funds from Vanguard, Fidelity, and Schwab.
Mutual funds can carry extra fees like load fees and 12b-1 fees. Many are no-load these days, but it pays to check.
For index investors, the difference often comes down to which provider you use.
Tax Efficiency
ETFs are usually more tax-efficient than mutual funds.
ETFs use a process called in-kind redemption. This lets the fund swap shares without triggering capital gains. Mutual funds may need to sell securities when investors redeem, which can create taxable distributions.
For a taxable brokerage account, ETFs may save you on year-end taxes. Inside a Roth IRA or 401(k), this difference does not matter much. Our brokerage account vs retirement account guide can help you decide which wrapper fits each holding.
Minimums and Fractional Investing
Mutual funds often require minimum investments. Vanguard funds usually start at $1,000 or $3,000. Some Schwab and Fidelity index funds have no minimum.
ETFs do not have minimums in the same way. You buy whole shares at the market price, which could be $50 or $500 per share. With fractional shares on platforms like Robinhood and Public, you can buy as little as $1 of any ETF. To compare the two apps, see our Robinhood review and Public.com review.
This gives ETFs an edge for small investors who want to start with little money.

Dividend Reinvestment
Mutual funds typically reinvest dividends automatically and for free. The cash goes right back into more shares of the fund.
ETFs require dividend reinvestment to be set up at the brokerage level. Most major brokerages support this for free. It can take a day or two for the cash to be reinvested.
If hands-off compounding is your priority, both fund types can handle it well.
ETF vs Mutual Fund for Retirement Accounts
Inside a 401(k), mutual funds tend to dominate. Most plans offer mutual fund options rather than ETFs.
In an IRA, you can choose either. ETFs may have a slight edge thanks to lower fees and fractional shares. Mutual funds may still win if your provider has unique zero-fee options like FZROX. Mobile-first savers can also park ETF picks inside a Robinhood Roth IRA to capture contribution matches.
Many retirement investors use a mix.
ETF or Mutual Fund: Which Should You Choose?
For most new investors, ETFs offer a few advantages worth weighing:
- Lower expense ratios on average
- Tax efficiency in taxable accounts
- No investment minimums
- Fractional share support
- Intraday trading flexibility
Mutual funds are still strong picks when:
- You invest inside a 401(k) plan with limited ETF options
- You want automatic dividend reinvestment without setup
- You buy zero-fee mutual funds at Fidelity or Schwab
The good news is you do not have to choose one forever. Many portfolios hold both. You can use ETFs in a taxable Robinhood account and mutual funds in a 401(k).
Common Mistakes to Avoid
Whether you pick an ETF or mutual fund, a few habits can hurt returns.
- Chasing past returns: Last year's winner may not lead next year.
- Buying too many overlapping funds: Holding three S&P 500 funds adds no diversification.
- Ignoring fees: Even a 0.5% gap in expense ratios adds up over decades.
- Trading often: Even with no-commission ETFs, frequent trades can hurt returns.
A simple, low-cost approach often beats a complicated one.
Where Credit Building Fits
A strong credit score can lower your borrowing costs, which leaves more money to invest. Firstcard provides a secured credit card built to help users improve credit through everyday spending.

Frequently Asked Questions
Are ETFs always better than mutual funds?
Not always. ETFs win on tax efficiency, minimums, and intraday trading. Mutual funds may win inside a 401(k) or for investors who want fully automatic dividend reinvestment. The right pick depends on your account type and goals.
Can I lose money in both ETFs and mutual funds?
Yes, both carry market risk. Values can fall during downturns. Spreading money across many holdings can help manage that risk but does not remove it.
Which has lower fees, ETFs or mutual funds?
ETFs generally have lower expense ratios on average, but the gap is shrinking. Some mutual funds, like FZROX from Fidelity, charge no fee at all. Always check the expense ratio before buying.
Can I hold both ETFs and mutual funds in the same account?
Yes. Most brokerages let you mix both within one account. Many investors do this to take advantage of zero-fee funds while still using ETFs for taxable accounts.
