All but a few brokers offer access to mutual funds, making it easy for investors who are saving for retirement or another big goal. One of the more confusing aspects of choosing an online platform: Should you invest directly (via a mutual fund company’s brokerage platform) or indirectly (buying shares through another broker that offers them)?
Buying mutual funds directly from a mutual fund company: Going direct can save you money on transaction fees. For example, companies like Fidelity Investments and The Vanguard Group charge no mutual fund commissions to buy their funds via a brokerage account set up with them. Plus, going direct gets you access to the entire range of their fund offerings.
Investing in mutual funds through another discount broker: Many brokerages (including Fidelity and Vanguard) offer access to competitor’s mutual funds on their platforms. This makes it easy to purchase funds from multiple fund families without the administrative hassle of having to maintain multiple accounts. You can review a broker’s lineup of funds before signing up to make sure that it offers ones that you want.
Next, you’ll want to compare fees — including commissions and early redemption fees. (Note: On the funds themselves, you can expect to pay an expense ratio, which is a management fee that covers the costs of running the fund. See our roundup of low-fee funds for guidance.)
Here’s a closer look at some of the best mutual fund brokers for 2025 to help you determine the right fit for your investing journey.
Fidelity Investments launched four zero-fee funds in 2018 — making it the first financial company to offer mutual funds with zero expense ratios in the ongoing price war. The funds are: Fidelity Zero Total Market Index Fund (FZROX), Fidelity Zero International Index Fund (FZILX), Fidelity Zero Large Cap Index Fund (FNILX) and Fidelity Zero Extended Market Index Fund (FZIPX). And all Fidelity funds come without transaction fees (trading costs) as long as you hold the fund for at least 60 days. Plus, they are only available for purchase through a Fidelity account.
The Boston-based retirement giant, which has long had a prominent name in the mutual fund space, also offers nearly 3,300 no-transaction-fee mutual funds. Using the long-established broker, you’ll get access to a ton of research, screening tools and its namesake mutual funds, such as its iconic Magellan fund. You can also port all of your financial accounts onto its so-called full-view feature to understand all of your finances in one place, much as you might on a budgeting app like Mint.
