When it comes to investing in a diversified portfolio, two of the most common choices are exchange-traded funds (ETFs) and mutual funds. Both offer a convenient way to invest in a basket of assets—stocks, bonds, or other securities—without having to pick individual investments. But while they share similarities, they also have key differences that can impact your investment strategy, costs, tax efficiency, and flexibility.
In this guide, we’ll break down the pros and cons of ETFs and mutual funds to help you determine which one fits your financial goals.
What Are ETFs?
An ETF (exchange-traded fund) is a type of investment fund that trades on a stock exchange, just like individual stocks. It holds a collection of assets, often designed to track an index such as the S&P 500 or the Nasdaq-100.
Key Features of ETFs:
- Trades throughout the day like a stock
- Typically passively managed (index-tracking)
- Low expense ratios
- Transparent holdings
- Tax-efficient
What Are Mutual Funds?
A mutual fund pools money from investors to invest in a diversified portfolio of assets. These funds are priced once daily after the market closes, and you buy or sell shares directly from the fund provider at the net asset value (NAV).
Key Features of Mutual Funds:
- Trades once per day after market close
- Can be actively or passively managed
- May have higher expense ratios
- Often offered in retirement accounts like 401(k)s
- Can require minimum investments
Comparing ETFs and Mutual Funds
- Trading and Liquidity
ETFs:
- Bought and sold anytime during market hours
- Prices fluctuate throughout the day
- No minimum investment (you can buy a single share or fractional shares)
Mutual Funds:
- Buy or sell orders executed after market close at NAV
- Cannot trade during the day
- Often require a minimum investment (commonly $500 to $3,000)
Winner: ETFs offer greater trading flexibility and accessibility for small investors.
- Costs and Fees
ETFs:
- Lower expense ratios on average
- Most have no load fees (sales charges)
- Brokerage commissions were common but are now mostly eliminated
Mutual Funds:
- May charge load fees (front-end or back-end)
- Higher average expense ratios, especially for actively managed funds
- May have additional fees like account maintenance
Winner: ETFs tend to be more cost-effective, especially for long-term passive investors.
- Tax Efficiency
ETFs:
- More tax-efficient due to “in-kind” redemption process
- Less likely to generate capital gains distributions
Mutual Funds:
- Capital gains are passed on to shareholders more frequently
- Less tax-efficient due to portfolio turnover
Winner: ETFs are generally more tax-efficient, which benefits investors in taxable accounts.
- Management Style
ETFs:
- Mostly passive (track an index)
- Limited active ETFs are available, but growing in popularity
Mutual Funds:
- Wide range of active and passive options
- Actively managed funds aim to outperform the market (often at higher cost)
Winner: Mutual funds offer more options for active management, which may appeal to investors seeking potential outperformance (with added risk and fees).
- Accessibility and Use in Retirement Accounts
ETFs:
- Readily available through most online brokers
- Easy to buy in taxable accounts and IRAs
- Not always offered in 401(k) plans
Mutual Funds:
- Widely used in 401(k)s, pensions, and other employer-sponsored plans
- Some mutual funds are exclusive to certain institutions (e.g., Vanguard Admiral Shares)
Winner: Mutual funds are still dominant in employer-sponsored retirement plans, but ETFs are gaining ground in IRAs and individual brokerage accounts.

Both ETFs and mutual funds can be excellent tools for building wealth over time. The right choice depends on your investment goals, tax situation, trading style, and how you’re accessing the market.
For new investors with smaller amounts of capital, ETFs often offer the best combination of cost-efficiency and flexibility. If you’re investing through an employer retirement plan or seeking a hands-off approach with professional management, mutual funds may be a better fit.
