Original TECHi illustration: match the account, costs and investment control to your goal.
Originally written by Jenny Reed. Updated by Qaiser Sultan.
The right investment app depends on who will choose the investments, what account you need and what you will pay at your actual balance. A commission-free stock trade does not make an account free: subscriptions, fund expenses, advisory charges and transfer fees can matter more than the trade commission.
This comparison covers seven services available to eligible U.S. investors: SoFi, Robinhood, Fidelity, Vanguard, Acorns, Betterment and Wealthfront. It is based on their published product documents and fee schedules checked on October 18, 2026, rather than a hands-on performance test. The illustrations explain account choices; they are original TECHi graphics, not screenshots. The order is not a ranking, and no app can guarantee an investment return.
Compare the account before comparing the app
Self-directed brokerage accounts let you choose what to buy and sell. An automated advisory account selects and manages a portfolio under its agreement with you. A provider may offer both under the same brand, with different fees and minimums. Cash-management products introduce another set of terms. Check which legal entity and account type appear on the application.
| Provider and product | Investment control | Headline price | Important qualification |
|---|---|---|---|
| SoFi Active Invest | Self-directed | $0 stock/ETF commission; $5 to begin | $25 per six months of login inactivity |
| Robinhood investing | Self-directed | $0 stock/ETF commission | Paid extras and other charges separate |
| Fidelity brokerage | Self-directed | $0 online U.S. stock/ETF commission | Fund and special-service charges vary |
| Vanguard brokerage | Self-directed | $0 online stock/ETF commission | $25 annual service fee; waiver conditions |
| Acorns Bronze | Automated portfolio | $4/month | Subscription is $48/year; fund expenses separate |
| Betterment automated | Managed portfolio | $5/month or qualifying 0.25%/year | Deposit or balance conditions apply |
| Wealthfront Portfolio | Managed portfolio | 0.25%/year; $500 minimum | Other products have different terms |
The table summarizes the named products, not every plan each company sells. Fund expenses, spreads, regulatory charges and special-service fees may apply in addition to the headline price. Minimums for particular securities, margin and premium services can differ from the minimum to open an ordinary account. The linked schedules below are the place to check immediately before opening or transferring.
SoFi: check the self-directed schedule, including inactivity
SoFi Active Invest is the self-directed choice; its robo-advisor is a separate product. The October 1, 2026 fee schedule lists $0 opening and annual fees for self-directed accounts, a $5 minimum to begin investing, and commission-free online U.S.-listed stock and ETF trades. That makes it a candidate for someone who wants to select investments and can monitor the account.

The important qualification is inactivity: the same schedule lists $25 per account for every six months of login inactivity. It also lists a $100 outgoing ACATS transfer charge. These are different from a trading commission. The robo-advisor instead lists a 0.25% annual advisory fee and a $50 starting minimum. Do not apply the self-directed price to a managed portfolio, or assume a banking relationship removes investment-account charges.
Robinhood: distinguish the investing account from paid extras
Robinhood's trading-fee explanation says its investing account charges no opening or maintenance fee and no commission for stocks and ETFs. Regulatory and other transaction charges can still apply. This account is worth comparing if your requirement is choosing individual securities, rather than paying an adviser to manage the portfolio.

A subscription, margin borrowing, derivatives and crypto are separate decisions. Check the full fee schedule for the service you intend to use. An app making an order easy to enter does not establish that the order is appropriate. Before enabling borrowing or complex products, understand what can trigger a forced sale and whether a loss can exceed the cash committed. Promotional matches and premium benefits should be evaluated with their holding periods and eligibility conditions, not treated as unconditional investment returns.
Fidelity: broad investment choices, with fund-level distinctions
Fidelity's commission schedule lists no minimum to open an account and $0 commissions for online U.S. stock and ETF trades. It also shows that options contracts, some mutual funds and certain assisted transactions have different charges. The useful question is whether your intended investments and account type fit the schedule, not whether the entire brand can be called free.

Fidelity's ZERO range consists of zero-expense-ratio index mutual funds. They are not ETFs, and a zero expense ratio is a feature of those funds rather than every investment available through Fidelity. Compare the underlying holdings, account eligibility and transfer implications of the actual fund before choosing it. A long-term investor buying a fund and an active trader using options should not expect the same cost profile merely because both use the Fidelity app.
Vanguard: separate brokerage costs from managed advice
Vanguard's brokerage-account page distinguishes opening an account from meeting an investment's purchase minimum. Its current commission and fee schedule lists $0 online stock and ETF commissions. A $25 annual account-service fee may apply, with waivers including the specified electronic-delivery election. Check that election rather than assuming it is active.

Vanguard funds have their own expenses, and non-Vanguard funds or special services can carry other charges. Digital Advisor is a separate managed service with its own minimum and advisory pricing; the brokerage's zero online commission does not describe its total cost. This distinction matters for someone choosing between managing a fund portfolio personally and delegating allocation and rebalancing. Read the advisory agreement if you want the latter.
Acorns: translate the monthly subscription into annual dollars
Acorns' published plans are Bronze at $4 a month, Silver at $8 and Gold at $12. The service combines automated investing with features that vary by subscription. Round-Ups can direct spare change toward investing, while higher tiers add services. Choose the features you will actually use rather than valuing the whole bundle as if every benefit were cash.

The small-balance arithmetic is the main consideration. Bronze costs $48 over 12 months. Against a hypothetical constant $500 balance, that is 9.6% of the balance before fund expenses; against $5,000 it is 0.96%. These percentages describe the subscription relative to assumed balances, not an annual percentage fee charged by Acorns, an investment return or an estimate for an account receiving new deposits. The subscription may support several services, so this calculation is a cost lens rather than a like-for-like advisory-fee ranking.
Betterment: eligibility changes the automated-investing price
Betterment's pricing page lists $5 a month as the base price for automated investing. It switches to 0.25% annually when qualifying recurring monthly deposits or transfers total at least $200, or qualifying balances reach $24,000. The page specifies which accounts count toward qualification. Traditional portfolios have no minimum balance, but that does not mean the monthly charge is immaterial at a low balance.

At an assumed constant $1,000 invested balance, $5 a month totals $60 a year; 0.25% would equal $2.50 if the account qualifies for that pricing. This isolates the fee mechanism, excluding investment changes and fund expenses. Recurring deposits would change the balance, so $2.50 is not a forecast bill for a depositing customer. Betterment also advertises self-directed stock and ETF trading without its automated management fee; that is a different service. Tax-management features can be useful, but their value depends on the investor's tax situation and other accounts.
Wealthfront: identify the portfolio and its current agreement
Wealthfront's pricing page lists a 0.25% annual advisory fee for Wealthfront Portfolio. Its October 2026 adviser brochure sets a $500 minimum to open and maintain that portfolio, with separate terms for other products. An illustrative constant $10,000 balance would incur $25 a year at 0.25%, before underlying fund expenses and other applicable costs.

The brochure also says new applications for the older Stock Investing Account stopped on October 15, 2026, and existing clients may transition to a separate self-directed brokerage account. Older comparisons can therefore describe a product a new customer cannot open on the same terms. Automated rebalancing and tax-loss harvesting do not guarantee a better after-tax result. Outside holdings and transactions can affect taxes, so assess the complete portfolio rather than treating a projected tax benefit as a fee refund.
Why the smallest headline fee can be misleading
A useful comparison starts with annual dollars for the exact service. A hypothetical 0.25% advisory fee on a constant $500 balance is $1.25 a year; at $10,000 it is $25. A $4 monthly subscription remains $48 in either case. That does not prove the subscription is worse: the services differ, and the customer may use other bundled benefits. It does show why a monthly dollar figure and an annual percentage cannot be compared at a glance.
Add the fund expense ratio, expected transfer or service charges and any subscription you actually need. Keep borrowing costs separate. Then ask what work the fee buys: security selection, portfolio management, tax features, advice or simply access to an account. Avoid assuming that a backtested model, a star rating or a sign-up offer measures future performance.
Protection and account security are different questions
SIPC protection concerns missing cash and securities at a troubled member brokerage, subject to its rules and limits: up to $500,000, including a $250,000 cash limit. It does not reimburse market losses. Do not extend that description to every crypto asset, derivative or cash product shown in an app. Bank-deposit insurance is a separate framework; check the actual bank, account ownership and program conditions for any deposit product.
Before funding, verify the provider's legal entity, enable the strongest available sign-in protection, secure the email account used for recovery and confirm the official support route. TECHi's online-banking safety guide explains the distinction between protecting access and verifying a payment request. For a trading strategy, read the separate guide to evaluating automated trading bots before granting software trading permissions.
Choose the account that fits your goal, investment control and total costs. Then recheck its current agreement. A useful app helps you follow a plan; it does not supply the plan or remove the possibility of loss.
