You can buy mutual funds through a brokerage account, directly from a fund company, or through your employer's retirement plan
The place you buy mutual funds depends on what type of account you want and how much control you want over your choices. A brokerage account at a firm like Fidelity, Charles Schwab, or Vanguard gives you access to thousands of funds from many companies in one place. A direct purchase from a fund company like Vanguard or T. Rowe Price limits you to that company's funds but sometimes charges lower fees. An employer retirement plan like a 401(k) or 403(b) offers a smaller menu of pre-selected funds, but often includes an employer match that makes it the most valuable option if it's available to you.
Each route has different costs, different tax treatment, and different rules about when you can withdraw money. The right choice depends on whether you're saving for retirement or a shorter-term goal, how much you have to invest, and whether you want simplicity or maximum choice.
Key Takeaways
- Brokerage accounts at major firms give you access to funds from many companies and work for any savings goal, but you pay capital gains taxes on profits each year.
- Buying directly from a fund company works if you want only that company's funds and may have lower minimum investments, but you lose the ability to diversify across fund families easily.
- Employer retirement plans like 401(k)s offer tax-deferred growth and often include employer matching, making them the priority if your employer offers one.
- IRAs (traditional or Roth) are retirement accounts you open yourself and can hold funds from any company, with tax benefits that make them valuable for long-term saving.
- Each account type has different rules about fees, minimum investments, and when you can withdraw money without penalty.
Brokerage accounts: the most flexible option
A brokerage account is a regular investment account you open with a financial firm. You fund it with your own money (not pre-tax income), buy and sell investments as you choose, and can withdraw money anytime without penalty. The major brokerages—Fidelity, Charles Schwab, E*TRADE, TD Ameritrade, and Vanguard—all offer mutual fund investing with no account minimums or very low ones ($0 to $500 depending on the firm).
The main advantage is choice: you can buy mutual funds from any fund company, compare them side by side, and build a portfolio that mixes funds from different families. The main disadvantage is taxes. When a mutual fund distributes dividends or capital gains, you owe taxes on those profits that year, even if you don't sell the fund. If the fund manager sells holdings at a profit inside the fund, you pay tax on that gain too. This makes brokerage accounts less efficient for long-term saving than retirement accounts.
Brokerage accounts work well for saving toward a house down payment, a car, or any goal less than five years away. They also work as a second savings account once you've maxed out your retirement plan contributions.
Direct purchase from a fund company
You can open an account directly with Vanguard, Fidelity, T. Rowe Price, American Funds, or other fund companies and buy only their mutual funds. This route often has lower minimum investments than a brokerage account (sometimes $50 to $100 instead of $500) and may charge lower fees because you're buying directly from the source.
The trade-off is that you're limited to one company's fund lineup. If you want to own a Vanguard index fund and a T. Rowe Price actively managed fund, you'd need accounts at both companies. You also lose the convenience of a single login and statement for all your investments. Direct purchase makes sense if you've decided on one fund family and want to keep things simple, or if you're starting with a small amount of money and want the lowest possible minimum.
Employer retirement plans: 401(k), 403(b), and similar
If your employer offers a retirement plan, that's usually the best place to start. A 401(k) (offered by for-profit companies) or 403(b) (offered by nonprofits and schools) lets you contribute pre-tax money from your paycheck, which lowers your taxable income that year. The money grows tax-deferred, meaning you don't pay taxes on gains until you withdraw it in retirement. Many employers also match a portion of what you contribute—typically 3% to 6% of your salary—which is immediate, may provide return on your money.
The menu of funds in an employer plan is usually smaller than what you'd find at a brokerage (often 10 to 30 options instead of thousands), but the funds are pre-screened by the plan administrator. You can't withdraw money before age 59½ without paying a 10% penalty plus income tax, with limited exceptions. Despite that restriction, the tax deferral and employer match make employer plans the priority for retirement saving if you have access to one.
Individual Retirement Accounts (IRAs)
An IRA is a retirement account you open yourself at a brokerage, fund company, or bank. You can buy mutual funds from any company within the same IRA account, giving you the flexibility of a brokerage account with the tax benefits of a retirement plan. A traditional IRA lets you deduct contributions from your taxes (with income limits if you have an employer plan), and the money grows tax-deferred. A Roth IRA doesn't give you a tax deduction upfront, but withdrawals in retirement are tax-free.
The annual contribution limit is the same for both types—$7,000 for 2024 if you're under 50, $8,000 if you're 50 or older—and you can't withdraw money before 59½ without a 10% penalty, with some exceptions. IRAs are the second priority after maxing out an employer match, because they offer tax efficiency and let you choose your own investments. If you're self-employed or have no employer plan, an IRA or Solo 401(k) is how you save for retirement.
Comparing costs and minimums across account types
| Account Type | Typical Minimum | Annual Contribution Limit | Tax Treatment | Withdrawal Penalty |
|---|---|---|---|---|
| Brokerage | $0–$500 | None | Taxed each year on gains | None (anytime) |
| Direct from fund company | $50–$500 | None | Taxed each year on gains | None (anytime) |
| 401(k) / 403(b) | Employer-set | $23,500 (2024) | Tax-deferred | 10% + income tax before 59½ |
| Traditional IRA | $0–$500 | $7,000 (2024) | Tax-deferred | 10% + income tax before 59½ |
| Roth IRA | $0–$500 | $7,000 (2024) | Tax-free growth | 10% + income tax before 59½ |
Most brokerages and fund companies have eliminated account minimums or set them very low. The real cost difference comes from fund expense ratios (the annual fee charged by the fund itself) and whether the brokerage charges trading commissions. Most major brokerages charge no commission to buy mutual funds, but some funds carry a sales load (an upfront fee) or back-end load (a fee when you sell). Direct purchases from fund companies typically avoid these loads.
How to choose which account to open first
Start with an employer 401(k) or 403(b) if your employer offers one and matches contributions—contribute at least enough to capture the full match. That's assistance programs and the tax deferral makes it the most efficient place to save. If you don't have an employer plan, or after you've captured the full match, open a traditional or Roth IRA at a major brokerage. You'll get tax benefits, access to thousands of funds, and low or no minimums.
Once you've maxed out your IRA contribution for the year ($7,000 in 2024), open a brokerage account for additional savings. A brokerage account has no contribution limit and no withdrawal penalties, so it's the right place for money you might need before retirement or for saving beyond what retirement accounts allow.
If you want simplicity and have decided on one fund family, a direct account with that company works, but you'll lose flexibility if your needs change. Most people benefit from opening accounts at a major brokerage like Fidelity or Schwab, where you can hold both retirement and non-retirement accounts in one place.
Frequently Asked Questions
Can I buy mutual funds through a bank?
Yes. Most banks offer brokerage services and can sell you mutual funds, though their selection and fees may be limited compared to a dedicated brokerage. Banks are convenient if you already have a checking account there, but you'll often find better fund choices and lower costs at Fidelity, Schwab, or Vanguard.
Do I need a lot of money to start buying mutual funds?
No. Most brokerages have no minimum, and some fund companies set minimums as low as $50 to $100. Employer retirement plans may require you to contribute a minimum percentage of your paycheck, but that's usually 1% to 3%, not a dollar amount. Start with what you have.
What's the difference between buying a mutual fund and buying individual stocks?
A mutual fund pools money from many investors to buy a basket of stocks or bonds, spreading risk across many holdings. Individual stocks are single companies. You buy both the same way—through a brokerage account—but mutual funds are simpler for beginners because you get instant diversification without picking individual companies.
Can I move my mutual funds from one account to another?
Yes, but the rules depend on the account type. Between two brokerage accounts, you can transfer funds without selling them (called an in-kind transfer). Between a brokerage and a retirement account, you usually have to sell and rebuy, which triggers taxes in the brokerage account. Moving money between retirement accounts (like rolling a 401(k) to an IRA) has specific rules—ask your plan administrator or the receiving institution how to do it without penalties.
Should I buy mutual funds through a financial advisor instead?
An advisor can help you build a plan and choose funds, but you pay for that service through fees or commissions. If you're comfortable reading fund fact sheets and building a simple portfolio of low-cost index funds, you don't need an advisor. If you have a complex situation—multiple income sources, inheritance, or significant assets—an advisor may be worth the cost. Either way, you still buy the funds through a brokerage or retirement account; the advisor just helps you decide which ones.
