You can buy mutual funds through a brokerage account, directly from a fund company, or through a financial advisor

The place you buy mutual funds depends on how much control you want, how much you want to pay in fees, and whether you want professional guidance. Most people use a brokerage account — an online platform where you can buy thousands of different funds from different companies in one place. Others buy directly from the fund company itself, which cuts out the middleman but limits your choices to that company's funds. A third option is working with a financial advisor, who buys funds on your behalf, usually charging a percentage of what you invest.

Each route has real trade-offs. Brokerages are convenient and often cheap, but you make all the decisions yourself. Direct purchases from a fund company are straightforward if you know exactly what you want. Advisors take the decision-making off your plate but cost more money. Your choice depends on whether you value simplicity, low cost, or professional guidance most.

Key Takeaways

  • Online brokerages like Fidelity, Schwab, and Vanguard let you buy mutual funds from many companies in one account, often with no minimum investment or trading fees.
  • Buying directly from a fund company like Vanguard or T. Rowe Price works if you want only that company's funds and are comfortable managing your own account.
  • Financial advisors buy funds for you and charge either a flat fee, hourly rate, or a percentage of your assets, and you should understand their fee structure before hiring one.
  • Most brokerages now offer commission-free mutual fund trades, but some funds carry internal expense ratios that vary by fund and company.
  • Your choice affects how much you pay in fees, how many funds you can choose from, and how much time you spend managing your investments.

Opening an account at an online brokerage

An online brokerage is the most common place people buy mutual funds. You open an account, deposit money, and then search for and buy funds from a catalog that includes offerings from dozens of fund companies. Major brokerages include Fidelity, Charles Schwab, E*TRADE, TD Ameritrade, and Vanguard. Each one offers thousands of mutual funds, usually with no commission per trade and no minimum investment requirement.

The process is straightforward: you create an account online, verify your identity, link a bank account, transfer money in, and then place an order for the fund you want. The fund shares appear in your account within a few business days. You can hold the funds as long as you want, buy more shares, or sell them whenever you choose. The brokerage handles the paperwork and sends you tax documents at year-end.

The main cost is the fund's internal expense ratio — a yearly fee charged by the fund company itself, not the brokerage. This ratio varies widely depending on the fund type and company. Index funds typically charge 0.03% to 0.20% per year, while actively managed funds often charge 0.50% to 1.50% or higher. You pay this fee automatically; it comes out of the fund's value before you see your returns.

Buying directly from a fund company

You can also buy mutual funds directly from the fund company that manages them, without going through a brokerage. Vanguard, Fidelity, T. Rowe Price, American Funds, and Schwab all allow this. You open an account with the fund company, deposit money, and buy their funds directly. This cuts out the middleman and can feel simpler if you know exactly which funds you want.

The downside is that you can only buy that company's funds. If you want to own funds from three different companies, you would need three separate accounts. You also have to manage each account separately — different logins, different statements, different tax forms. For someone buying a single fund and leaving it alone for years, this works fine. For someone building a diversified portfolio across multiple fund companies, it becomes tedious.

Many fund companies have lowered or eliminated minimum investment requirements, so you can often start with $100 or $500. The expense ratios are the same whether you buy directly or through a brokerage — the fee structure is set by the fund company, not by where you buy.

Working with a financial advisor

A financial advisor can research funds, build a portfolio, and buy and manage the funds for you. This removes the decision-making burden and can be valuable if you are unsure what to buy or want ongoing professional guidance. Advisors typically work with brokerages or fund companies to execute trades on your behalf.

Advisors charge in three main ways. Some charge a flat fee — a set amount per year or per transaction, regardless of how much money you invest. Others charge an hourly rate, similar to hiring a lawyer or accountant. A third group charges assets under management (AUM) — typically 0.5% to 1.5% of your total portfolio value per year. This last model means the advisor's fee grows as your portfolio grows, which can add up quickly on large accounts.

Before hiring an advisor, ask them directly how they are paid and whether they are a fiduciary — meaning they are legally required to act in your best interest. Not all advisors are fiduciaries; some are only required to recommend "suitable" investments, which is a weaker standard. A fiduciary advisor must disclose conflicts of interest and cannot recommend a high-fee fund when a low-fee option would serve you better.

Mutual funds through employer retirement plans

If your employer offers a 401(k), 403(b), or similar retirement plan, you buy mutual funds through that plan. You do not open a separate brokerage account; instead, you choose from a menu of funds the plan offers, and money comes out of your paycheck automatically. The plan administrator — often a company like Fidelity, Vanguard, or Schwab — handles the account.

The fund selection is limited to what the plan includes, which might be 20 to 50 options rather than thousands. However, employer plans often offer matching contributions, which is assistance programs, and the money you invest reduces your taxable income that year. The expense ratios on retirement plan funds can vary widely, so it is worth comparing the options available to you.

Robo-advisors and automated investing platforms

A robo-advisor is a hybrid between a brokerage and a human advisor. You answer questions about your age, goals, and risk tolerance, and an algorithm builds a portfolio of mutual funds (or exchange-traded funds) for you. The platform then automatically buys and rebalances your portfolio over time. Examples include Betterment, Wealthfront, and Vanguard Personal Advisor Services.

Robo-advisors typically charge 0.25% to 0.50% per year in fees, which is less than a human advisor but more than a self-directed brokerage account. You get professional portfolio construction and ongoing management without paying for a human advisor's time. This works well for people who want guidance but do not have enough money to attract a traditional advisor or who prefer a hands-off approach.

Comparing costs across purchase methods

The total cost of owning a mutual fund depends on where you buy it and which fund you choose. A fund's expense ratio is the same everywhere — Vanguard's Total Stock Market Index Fund charges the same 0.03% whether you buy it through Fidelity, Schwab, or directly from Vanguard. But the total cost to you also includes any advisory fees, account fees, or trading commissions.

An online brokerage with no trading commissions and a low-cost index fund might cost you 0.03% to 0.10% per year. A robo-advisor using similar funds might cost 0.25% to 0.50%. A human advisor charging 1% of assets under management costs significantly more. Over 20 or 30 years, these differences compound. A 0.5% annual fee versus a 0.1% fee means you end up with noticeably less money at retirement, all else equal.

Frequently Asked Questions

Do I need a minimum amount of money to start buying mutual funds?

Most online brokerages have no minimum investment — you can open an account and buy a single fund share with $100 or less. Some fund companies or advisors may require $500 to $2,500 to open an account, but this is becoming less common. Check the specific brokerage or fund company's requirements before opening an account.

Can I buy mutual funds through my bank?

Yes, many banks offer brokerage services and can sell you mutual funds. However, banks often charge higher fees than standalone brokerages and may push you toward their own funds. You typically get better pricing and more choices through a dedicated brokerage like Fidelity or Schwab.

What is the difference between buying a mutual fund and buying individual stocks?

A mutual fund pools money from many investors to buy a diversified basket of stocks, bonds, or other securities. You buy one fund and own a piece of many holdings. Buying individual stocks means you own shares of one company at a time. Mutual funds reduce risk through diversification and require less research, but individual stocks offer more control.

Can I move my mutual funds from one brokerage to another?

Yes, you can transfer funds between brokerages through a process called an ACAT (Automated Customer Account Transfer). The receiving brokerage usually handles the paperwork. The transfer typically takes five to ten business days. You may owe capital gains taxes if the funds have increased in value since you bought them, depending on whether the account is taxable or tax-deferred.

What happens if a brokerage goes out of business?

Your mutual funds are protected by SIPC (Securities Investor Protection Corporation) insurance, which covers up to $500,000 per account if a brokerage fails. This protection covers the value of your funds, not losses from market declines. Larger brokerages like Fidelity and Schwab also carry additional insurance beyond SIPC requirements.
