Pros and cons
Acorns Checking
Pros
- Entry is $0, against $500 for eToro portfolios and $100 for Axos Invest managed portfolios, so small sums are enough to begin.
- Fractional shares, a mobile app and a demo account all sit in the feature list (fractional shares, mobile app and demo account), so you can try the app and build positions in parts before committing more.
- Regulated in the US by the FDIC, with SIPC protection on file, so the money sits inside a named US regulator and scheme.
Cons
- The account fee runs $48 to $144 while the median account fee across the site is €0, so the charge is the line to weigh against a small balance.
- Support runs on help centre only, so there is no route on file to a call or a live chat reply for anything urgent.
- The account types listed are ira only, so a UK ISA or a pension container is not on the list for readers in the UK and Europe.
Ally Bank
Pros
- A stock trade costs $0 and the account fee is $0, so holding a US portfolio costs nothing at the platform level.
- The inactivity fee is $0, and Ally ranks 1 on that measure among 56, so a dormant balance is not quietly drained.
- Regulated in the US by SEC, FINRA and FDIC, with investor protection recorded as SIPC up to USD 500,000 and an FDIC certificate of FDIC cert 57803.
Cons
- The automated portfolios take a management fee of 0% to 0.3% a year, so a free account is not the whole cost picture.
- Options carry $0.50 per contract, so the commission-free model in commission free does not reach derivative trading.
- Account types run to joint, ira and roth ira, with no wrapper for a tax-sheltered investor who is not saving through a retirement account.
Who each suits
Acorns Checking
Who it suits
- US beginners, since the audience on file is beginners and a minimum investment of $0 keeps the first decision small.
- People who want a cash account and an invested portfolio in the same place, with fractional shares in the feature list (fractional shares, mobile app and demo account).
- Investors happy to hand selection to a robo portfolio rather than pick shares, given portfolio types of etf, esg and crypto.
Who should look elsewhere
- Anyone budgeting around a UK ISA or a pension wrapper: the account types here are ira only, while an ISA appears on 22% of the brands on the site, so eToro or Vivid Standard serve that audience better.
- Readers who prefer a larger opening commitment alongside a managed portfolio, since Axos Invest starts at $100 where this one starts at $0.
Ally Bank
Who it suits
- US savers who want commission-free share dealing, a minimum deposit of $0 and an account fee of $0.
- Retirement investors, since joint, ira and roth ira covers individual retirement accounts and joint accounts.
- People who would rather ring than email, since email, chat and phone includes phone, chat, email and a help centre.
Who should look elsewhere
- Traders after forex, contracts for difference or crypto, since stocks, etfs and options stops at the US list while stocks, etfs and forex goes further.
- Anyone who wants leveraged index exposure on the same account, where CFI covers stocks, etfs and forex and Ally does not.

Questions about each
Acorns Checking
What does it cost to hold an Acorns Checking account?+
Trading is the cheap part: a stock trade costs $0 and the pricing model is commission free, so buying small amounts of shares adds no commission to the bill. The charge sits elsewhere, in the account fee, which runs $48 to $144, and the inactivity fee is $0, so a dormant account is not penalised. Weigh the subscription line against the size of your balance.
How much do I need to open an account?+
Less than most rivals. The minimum deposit is $0 and the minimum investment is $0, so there is no practical floor to clear before you start. For comparison, eToro's portfolio route starts at $500, Axos Invest's managed portfolios at $100 and Vivid Standard at €2. Small sums are enough to begin here.
Ally Bank
What does it cost to open a self-directed account and place a trade?+
Opening costs nothing beyond the deposit itself, and the minimum deposit is $0. Trading shares carries a fee of $0 and the account fee is $0, so a small starter order does not eat into the position. Options are the exception and are priced separately per contract.
Is there a charge if I leave the account empty?+
No. The inactivity fee is $0, which means an account you stop using carries no monthly drain on the balance. It matters most for anyone splitting cash between trading and holding, because a dormant account here does not quietly shave the value of what sits in it while a decision is pending.
