For long-term ETF investing, choose a brokerage account by comparing the service you need, all-in costs, how idle cash is handled, recurring-investment features, and how easily you can move your holdings later. A $0 ETF commission alone does not tell you what the account will cost or whether its features fit your investing routine.
This guide is for U.S. individual investors comparing self-directed brokerage accounts and advisory services. Broker rates and features change, so record the date of any rate, yield, or minimum you compare and confirm it in the firm’s current disclosures.
How to compare brokerage accounts for ETF investing
Compare candidate firms using the same investor profile and expected activity. A worksheet helps make trade-offs visible instead of letting one advertised feature decide for you.
| What to compare | What to record |
|---|---|
| Account and service | Whether the account is self-directed, advisory, or both; what the firm will do; and what the agreement commits it to provide. |
| Total costs | ETF expense ratio, commissions or other trade costs, account or maintenance charges, inactivity or closing fees, wire and transfer fees, and margin interest if relevant. |
| Uninvested cash | Default destination, current rate or yield, whether it is automatic, available alternatives, and the applicable protection. |
| Contributions | Whether your ETFs are eligible for recurring dollar-based purchases or fractional shares; minimums, order timing, fees, and treatment of fractional positions on transfer. |
| Portability and support | Which of your existing assets the firm accepts, what happens to assets it will not accept, transfer charges, and the support or advice included. |
| Firm checks | Form CRS, the full fee schedule and account agreement, BrokerCheck results, and SIPC membership and limits. |
Put a date beside changing figures such as yields, fees, or minimums. For an investor who periodically buys a broad-market ETF without needing advice, recurring costs and the purchase workflow may deserve the most attention. Someone seeking ongoing recommendations or management should compare the service and its fee with the help actually wanted.
Decide whether you want self-directed brokerage or advice
A brokerage firm can accept and execute orders and may also provide recommendations. An advisory relationship may involve ongoing advice or discretion and can charge an asset-based or other fee. Some firms offer both services, so identify the capacity in which the firm will act and what each arrangement includes.
FINRA notes that a buy-and-hold investor may prefer transaction-based fees, while an asset-based fee may make sense for someone who wants ongoing advice or investment decisions handled for them. Neither description replaces the actual terms: read the account agreement to see which services and charges apply. Use each prospective firm’s Form CRS to compare services, costs, conflicts of interest, and disciplinary disclosures, alongside its full fee schedule and agreement. See FINRA’s overview of brokerage and advisory accounts.
Calculate the full cost, not just the ETF commission
There are two broad layers of cost: charges from the brokerage and expenses inside the fund. ETF operating expenses are generally deducted from fund assets and reduce returns, even though the investor may not see a separate bill. The expense ratio and other fund details are disclosed in the prospectus.
Rank #2
- Broker charges: Check commissions, transaction costs or markups, maintenance and inactivity charges, closing fees, wire and outgoing-transfer charges, and margin interest if you plan to borrow.
- Fund expenses: Compare the ETF’s annual operating expense ratio and review its prospectus.
“Commission-free” refers to a particular trading charge, not every possible cost. The SEC explains what to consider when opening a brokerage account and how investment fees and expenses affect returns. A broker’s $0 offer may apply only to eligible trades made through specified channels; check its exclusions and current terms.
Check where uninvested cash goes
Cash awaiting investment may stay at the brokerage, move automatically to a bank deposit program, or be invested in a money-market fund. These are not interchangeable: rates, risks, and protections differ, and the broker may have a financial incentive in the sweep option it uses. Read the account’s cash-sweep disclosure to learn the default destination, whether you can choose another option, and the current rate or yield.
The SEC distinguishes brokerage cash and money-market funds from bank sweep deposits held outside the brokerage. Depending on the arrangement, brokerage cash or a qualifying money-market fund may receive SIPC treatment in a covered liquidation; bank deposits may instead be eligible for FDIC coverage subject to applicable rules and limits. Verify where the money is held and which institution holds it. SIPC does not insure investment performance or reimburse losses caused by falling market prices. See the SEC’s guidance on brokerage account cash sweep programs and what SIPC protection covers.
Match recurring investing and fractional shares to your routine
Recurring dollar-based purchases and fractional shares can make it easier to invest regular contributions, including amounts too small to buy a whole share. But availability and program terms vary by firm and by ETF. Before relying on automation, confirm your chosen funds are eligible, the minimum contribution, when orders are placed, and whether fees apply.
Fractional positions can also have limits involving voting rights, liquidity, fees, and transfers. They generally cannot move intact to a different brokerage, so they may need to be sold when an account is transferred. That can affect both your holdings and the tax consequences of the move. The SEC describes these considerations in its guidance on fractional-share investing. Ask the firm how its recurring program handles skipped or failed orders and fractional balances before setting it up.

Consider how ETFs fit the account’s tax treatment
ETFs trade on an exchange during the trading day, and investors need a brokerage account to buy, sell, and hold ETF shares. In a taxable account, an 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 guarantee a particular tax outcome.
Holding an ETF rather than a mutual fund inside a tax-advantaged account such as an IRA or 401(k) does not, by itself, change the account’s tax treatment, according to the SEC’s Investor Bulletin on mutual funds and ETFs. Whether a taxable brokerage account or an IRA fits your circumstances depends on the account rules and your individual tax situation; the general points here are not individualized tax advice.

Portability can matter years after opening an account, so check whether the receiving firm accepts every position you own. Ask what happens to assets it will not accept, what the outgoing or closing fees are, and whether fractional shares must be sold. Selling a non-transferable holding may have tax consequences; do not assume a transfer or sale is tax-neutral.
The SEC’s overview of transferring a brokerage account explains why investors should review both firms’ requirements and potential costs before moving assets.

Verify the firm and compare dated terms
Check a broker or representative through FINRA BrokerCheck. Confirm the firm’s SIPC membership and understand what SIPC does and does not cover; it is not protection against ordinary investment losses.
Rates and broker features are snapshots, not permanent rankings. For example, a Vanguard comparison page says its competitor information was gathered from the respective websites as of September 21, 2026, and may change without notice. It reported these cash figures on that date:
| Product or program | Reported figure | Source and date |
|---|---|---|
| Vanguard Federal Money Market Fund 7-day yield | 3.71% | Vanguard comparison page, September 21, 2026 |
| Fidelity Government Money Market Fund 7-day yield | 3.41% | Vanguard comparison page, September 21, 2026 |
| Schwab default sweep APY | 0.01% | Vanguard comparison page, September 21, 2026 |
| E*TRADE Bank Deposit Program APY | 0.15% | Vanguard comparison page, September 21, 2026 |
| Robinhood APY for non-Gold subscription customers | 0.00% | Vanguard comparison page, September 21, 2026 |
These dated figures describe different cash products and are not directly comparable in every respect or a recommendation to choose a particular firm. Check the Vanguard comparison and its current disclosures, then verify any candidate’s present rate and terms directly with that provider before opening an account.
