ETF vs. mutual fund: what’s the difference?

Reviewed by Rachel CareyUpdated December 2, 2025

ETFs and mutual funds are investment pools with a similar structure that generally have different management styles. Here’s what you need to know about the similarities and differences, and how that can help you decide which you prefer to invest in.

More than 68 million US households own mutual funds as part of their retirement portfolio. 

They predate ETFs, which weren’t created in the US until 1993. 

If you’re wondering what the difference is and which one you should invest in, you’ll find it in this article.   

What are the similarities between mutual funds and ETFs?

Mutual funds and ETFs are both investments created from a pool of diverse securities, though they share many similarities. 

Diversified portfolio

Mutual funds and ETFs both put together a group of investments that offer broad exposure to different asset classes and niche markets. They’re less risky than owning individual stocks and bonds.

Similar structure

Both mutual funds and ETFs are investment vehicles that pool stocks, bonds, and other securities. Investors buy shares of a mutual fund or ETF rather than individual investments. 

Wide variety of investment options

Both ETFs and mutual funds have buckets of investments organized around a central goal or theme. You can buy mutual funds and ETFs that invest in income, dividend stocks, real estate, healthcare, technology, energy, international stocks, emerging markets, and more. 

What’s the difference between mutual funds and ETFs?

Although ETFs and mutual funds share many features, they differ in how they trade, what they cost, and how they’re managed.

ETF vs. mutual fund: How are they managed?

ETFs and mutual funds are managed differently. 

Mutual funds are typically actively managed, meaning there’s a core team that tracks investments to ensure they perform as expected. 

Actively managed doesn’t necessarily mean they’re making trades every day; rather, the investments are tracked and adjusted to achieve market outperformance. 

Most ETFs are passively managed, meaning a manager selects investments to track an index. The investments are typically long-term investments. 

ETF vs. mutual fund: Minimum investment

ETFs typically have a lower minimum investment requirement. 

It’s typically equivalent to the ETF’s share price; however, some brokerages offer fractional share investing, where you can invest with as little as $1. 

A mutual fund often has a higher minimum investment, which is a set dollar amount determined by the fund manager. Like ETFs, if your brokerage allows for fractional share trading, you may be able to invest in mutual funds with as little as $1. 

ETF vs. mutual fund: How are they traded?

Mutual funds are traded once at the end of the day for a single price once the NAV (net asset value) is calculated. The NAV is the value of the fund’s total assets, less any liabilities, divided by the number of shares. 

ETFs are bought and sold on an exchange throughout the day. The price fluctuates like a stock, so it’s advisable to watch the spread and the premium or discount relative to the ETF's NAV. 

ETF vs. mutual fund: Can I make automatic investments?

Automatic investing is common with most brokerages. Most will have a process where you set up the account, choose the investments (including ETFs or mutual funds), connect it to a funding source, and set the amount and frequency of the automatic investment. 

ETF vs. mutual fund: Tax efficiency

ETFs are generally more tax-efficient because of their passive nature. They have fewer taxable events than a mutual fund does. For example, an actively-managed mutual fund may sell a security, and you may need to pay capital gains (the “taxable event,” in other words). 

On the flip side, an actively managed mutual fund may have tax mitigation strategies to improve its tax efficiency. These may include capital loss carryovers from prior years, tax-loss harvesting, and so on.  

ETF vs. mutual fund: Costs and fees

The costs and fees for ETFs and mutual funds are calculated differently. 

For example, mutual funds may not charge trading commissions, but they do incur other operating expenses, sales loads, early redemption fees, and other fees. Since they’re actively managed, they usually cost more to own than ETFs.

Fees incurred while owning an ETF include the operating expense ratio (OER). Some brokerages charge a commission to trade ETFs (some do not), and it’s also important to consider the bid and ask spread as well as the discount or premium you’ll pay above the net asset value (NAV).   

What are the pros and cons of ETFs vs mutual funds?

Discuss the main advantages and disadvantages of each option.

ETFs and mutual funds both come with advantages and disadvantages. Here’s a quick summary of each. 

ETFs

Cons

  • Market risk: If the market falls, the ETF will, too.

  • Only trades once per day: You won’t be able to buy and sell mutual funds whenever you want. 

  • Higher minimum investments: Unless you have a brokerage that offers fractional share investing, you’ll typically need to come up with more to begin investing in mutual funds.
