Methodology: How we choose the best brokerage account for index funds

Finder’s investments experts reviewed 18 brokers to identify the best brokerage accounts for investing in index funds.

Our analysis is based on 147 key metrics collected directly from brokers, evaluating each platform across eight categories, including investment options, trading costs, account types and more.

Since most brokers offer access to index funds, we highlight the unique characteristics that make these brokers stand out for index fund investing.

We regularly update our best picks as products evolve, ensuring our recommendations reflect the most competitive options available in the market.

How do I open a brokerage account?

Complete the account opening process online in minutes with most investing platforms available today.

Choose an investing platform and complete a brief application by providing personal information such as your name, address, date of birth and Social Security number.

Completed applications are typically approved instantly, though the broker may take a couple of days to verify your information.

Then, connect a bank account to fund your account.

What to look for when choosing the best brokerage account

Finder’s picks for the best brokerage accounts provide a starting point for finding the right broker for your investing style and goals.

Consider the following factors when comparing your options:

  • Fees. From trading fees to miscellaneous fees, it’s important to understand the cost of trading and investing. Consider which investment products you plan to trade and the fees that apply, but also be mindful of any back-end fees, such as inactivity or transfer fees, that can also eat into your profit.
  • Tradable assets. Not every broker offers the same investment options. Stocks, options and ETFs are standard, but some brokers offer mutual funds, bonds, futures, forex, crypto and more. If you’re looking for the best broker for S&P 500 investing and other index funds, all brokers on our list offer access to these options.
  • Account types. What other account types, in addition to a brokerage account, does the broker offer? If you’re interested in saving for retirement, compare brokers offering IRAs. Consider your other investment needs and how important it is to maintain all your accounts under one roof.
  • Research and data tools. In-house research and tools simplify investing, as you don’t have to venture elsewhere to make an informed decision about an investment. If you’re a passive index investor, extensive research and analysis tools may not matter much. Active stock pickers may feel otherwise.
  • Mobile app reviews. Mobile trading is more popular than ever, allowing you to trade and invest from anywhere. Check out what current or previous customers say about the platform’s functionality.
  • Signup bonus. While it may not make sense to choose a broker solely based on whether it offers a signup bonus, a new customer incentive such as a free stock may be enough to help you choose one over another if all else is equal.

Frequently asked questions

What type of account do you need to invest in index funds?

Invest in index funds through various account types, including taxable brokerage accounts, IRAs and workplace retirement plans such as 401(k)s. The specific index funds available for trading depend on each broker’s offerings.

What are the downsides of investing in index funds?

Investing in index funds has some downsides, including limited flexibility, as they passively track a market index and cannot capitalize on market opportunities. They also offer no protection against market downturns since they reflect the overall market performance. Additionally, index funds may include underperforming stocks.
