For long-term ETF investing, choose a U.S. brokerage account by comparing the service you need, all-in costs, how uninvested cash is handled, recurring-investment options, protections, and the ability to move your holdings later. A $0 ETF commission alone does not tell you whether an account is a good fit.
How do I choose a brokerage account for long-term ETF investing?
Start by deciding whether you want to make your own investment decisions or pay for ongoing recommendations or management. Then compare candidate firms using the same ETF holdings and contribution habits, and verify terms in each firm’s Form CRS, account agreement, fee schedule, and cash-program disclosures.
- Choose the service type. Identify whether you want a self-directed brokerage account, an advisory account, or both. Check what the firm commits to do and whether it acts as a broker or adviser for the service you select. FINRA explains the distinction and the importance of account agreements in its brokerage-versus-advisory account guide.
- Estimate total costs. Look beyond the advertised trading commission to fund expenses, account fees, transaction costs, transfer charges, and any margin interest you expect to incur.
- Inspect the cash setup. Find out where idle cash goes by default, what rate applies, whether you can choose another option, and what protection applies to that specific destination.
- Check your contribution workflow. Confirm that the ETFs you plan to buy are eligible for recurring dollar-based investing or fractional shares, and review minimums, order timing, fees, and transfer treatment.
- Confirm portability and diligence. Ask whether the new broker accepts your current positions and check the firm or representative through FINRA BrokerCheck. Verify SIPC membership and understand what SIPC does—and does not—cover.
Use a worksheet to compare candidates side by side. Record the date beside rates, yields, and minimums because those terms can change.

|---|---|
| Account and service | Is it self-directed, advisory, or both? What service does the agreement promise, and in what capacity will the firm act? |
| Total cost | What are the ETF expense ratios, trading or transaction costs, maintenance or inactivity fees, closing or transfer charges, wire fees, and relevant margin rates? |
| Cash treatment | Does cash stay at the brokerage, sweep to a bank, or go into a money-market fund? What rate and protection apply, and can you choose? |
| Recurring purchases | Are your chosen ETFs eligible? What are the minimum, schedule, order timing, and any fees? What happens to fractional positions if you transfer? |
| Portability and service | Which assets will the receiving firm accept? What support or advice is available, and what does moving or closing the account cost? |
| Firm diligence | Can you confirm the firm or representative on FINRA BrokerCheck and verify the firm’s SIPC membership? |
If you periodically buy a broad-market ETF and do not want advice, focus on recurring costs and a workflow you will use consistently. If you want recommendations or management, compare the ongoing service and its fee with the help you actually need rather than assuming self-direction is automatically cheaper or better.
Brokerage or advisory account: which service do you need?
A brokerage firm can accept and carry out orders and may also make recommendations. An advisory service may provide ongoing advice or discretionary investment management and can charge an asset-based or other fee. The label alone does not establish what you will receive: read the agreement and determine the capacity in which a firm that offers both services is acting for your account.
FINRA notes that a buy-and-hold investor may prefer transaction-based fees to an asset-based charge, while an asset-based fee may make sense for someone seeking ongoing advice or investment decisions handled for them. That is a decision framework, not a universal rule; compare the actual service and charges. Prospective brokerage firms and SEC-registered advisers provide a Form CRS, a concise starting point for reviewing services, costs, conflicts, and disciplinary disclosures. Read it alongside the full agreement and fee schedule.

What fees should I compare besides ETF trading commissions?
“Commission-free” does not mean cost-free. Separate costs charged by the broker from expenses charged within the ETF.

- Commissions and other transaction costs, including possible markups.
- Account maintenance, inactivity, or closing fees.
- Outgoing transfer and wire fees.
- Margin interest, if you borrow to invest.
Check the current fee schedule for the account type and trade method you would use; promotional or limited trade terms may not apply to every transaction.
ETF operating expenses
An ETF’s annual operating expenses are generally deducted from fund assets and disclosed in its prospectus. They reduce returns even when a broker charges no online commission for eligible ETF trades. Compare the expense ratios of the funds you actually expect to hold, as well as the brokerage’s charges.
For example, Fidelity advertises $0 commission for eligible online U.S. stock and ETF trades and describes recurring investments and fractional shares, but its terms limit the $0 claim to specified online trades and list exclusions. See Fidelity’s commission and fee details and confirm current terms before opening an account.
How should I compare cash sweeps and account protection?
Uninvested cash may remain at the brokerage, sweep to a bank, or be placed in a money-market fund. These arrangements can have different rates, risks, and protections, and the broker may have a financial incentive related to its sweep program. Read the cash disclosure to identify the actual destination, whether the setting is automatic, whether alternatives are available, and the current rate. The SEC’s cash sweep programs bulletin explains the differences.
SIPC is not insurance against losses from falling market prices. In a covered brokerage liquidation, eligible brokerage cash and qualifying money-market fund holdings may receive SIPC protection subject to applicable limits. Bank-sweep deposits are held at banks outside the brokerage and may instead qualify for FDIC coverage within applicable limits. Do not infer protection from the word “cash”: verify where the money is held, the institution involved, and the applicable limits. See the SEC’s SIPC protection bulletin.
Rates are not necessarily comparable across products or firms. As a dated illustration, Vanguard’s comparison page reported figures as of September 21, 2026: 3.71% for Vanguard Federal Money Market Fund’s 7-day yield, 3.41% for Fidelity Government Money Market Fund’s 7-day yield, 0.01% for Schwab’s default sweep APY, 0.15% for E*TRADE Bank Deposit Program APY, and 0.00% for Robinhood customers without a Gold subscription. These are figures from Vanguard’s broker-published snapshot, not an independent audit or a recommendation; they describe different products and may have changed. Check the current terms at the firm. Vanguard’s comparison page provides its dated context.

Recurring investments and fractional shares can make it easier to invest regular dollar amounts, but availability and terms vary by broker and ETF. Before relying on the feature, check which funds qualify, the minimum purchase, schedule, order timing, and any costs. An automatic-investing button is useful only if it supports the investments and routine you intend to use.
Fractional-share programs can differ in voting rights, fees, liquidity, and transferability. Fractional positions generally cannot move intact to another broker and may need to be sold. The SEC describes these considerations in its fractional-share investing bulletin. Account for that limitation when weighing a recurring-investment feature against future portability.

Before opening the new account, ask the receiving firm whether it will accept every holding in the old account and identify positions that cannot transfer. Moving or closing an account may involve fees. If a non-transferable investment has to be sold, the sale could have tax consequences; do not assume a sale or transfer is tax-neutral. Fractional shares are one type of position that may not transfer. Review the SEC’s account transfer guidance and ask both firms about their process and charges.
Does ETF tax treatment affect the account choice?
ETF shares trade on an exchange, so investors need a brokerage account to buy, sell, and hold them. In a taxable account, an ETF investor may owe tax on capital-gain distributions; ETF in-kind mechanics can result in fewer such distributions than for comparable mutual funds, but do not eliminate tax considerations. In a tax-advantaged account such as an IRA or 401(k), tax treatment does not differ merely because the investment is an ETF rather than a mutual fund. These general points do not determine an individual investor’s tax outcome. The SEC’s ETF and mutual fund investor bulletin explains how the products work.
