About Acorns

Acorns offers premade ETF portfolios with risk tolerance-based asset allocations of stocks and bonds with taxable, brokerage and custodial accounts. This platform doesn’t offer individual stocks.

Other notable features include an online checking account and an online shopping portal to earn bonus investing cash. It’s also possible to round up debit and credit card purchases to increase your investing frequency.

About Robinhood

Robinhood is the most similar of the three services to a traditional online brokerage and the only one not charging a monthly account fee. Investors can trade almost any stock or ETF on-demand with a $1 minimum investment.

Only taxable brokerage accounts are available but customers can open a cash management account that earns interest and offers over 75,000 surcharge-free ATMs.

Read our Robinhood review for an in-depth look.

About Stash

Stash offers trades in thousands of stocks and ETFs but members pay a monthly subscription fee. It’s possible to open a taxable brokerage, tax-advantaged retirement, and custodial accounts.

It’s also possible to open an online banking account and a Stock-Back® Card1 that can earn stock rewards2 for well-known brands – like getting rewards at McDonald’s when you buy a Big Mac.

Platform Fees

Two of the three platforms charge a monthly fee. More expensive plans offer more features, including retirement and custodial accounts.

Acorns

Acorns has a fee structure similar to Stash with three monthly plans:

  • Lite ($1/month): Taxable brokerage account and rewards shopping portal
  • Personal ($3/month): Retirement account and online checking account
  • Family ($5/month): Child custodian accounts

You will need to choose the Personal of Family plan to access the online checking account in addition to the retirement and custodial accounts. The entry-level Lite plan only offers a taxable investment account.

Robinhood

Robinhood doesn’t charge a monthly or annual fee for its brokerage account or cash management account.

Stock and ETF trades are free but there is a commission on options contracts.

There is also an optional Robinhood Gold account that costs $5 per month.

Gold benefits include:

Learn more about Robinhood

Stash

Stash offers two monthly plans:

  • Growth ($3/month): Taxable account, Stock-Back Card1, banking account plus Retirement accounts, robo-advisor, personalized retirement advice
  • Stash+ ($9/month): Custodial accounts, exclusive Stock-Back Card1 bonuses, premium research

The monthly fee can be a nuisance but there are no add-on commission fees to buy or sell stocks and ETFs.

If you decide to invest with Stash, the best monthly plan depends on which investment accounts you want. The retirement and child custodian accounts require a higher plan fee.

Springing for the Stash+ plan can be worth the upgrade if you regularly use the Stock-Back Card1 for local and online purchases. Stash+ users get 1% Stock-Back® Rewards3.

Account Minimums

It’s possible to open a basic account with $0 with each brokerage. The monthly plan fees for Acorns start once your balance reaches $5.

There is always a $3 per month fee with Stash regardless of your balance.

Robinhood has a $1 minimum investment for buying stocks and funds. Options trades require purchasing at least 100 contracts.

Investment Options

All three platforms have different investment options.

Acorns

Acorns only offers five different stock and bond index ETF portfolios. Each portfolio pursues a different risk strategy:

  • Conservative (100% bonds)
  • Moderately conservative (40% stocks and 60% bonds)
  • Moderate (60% stocks and 40% bonds)
  • Moderately aggressive (80% stocks and 20% bonds)
  • Aggressive (100% stocks)

The platform rebalances the portfolio with each new investment. It’s possible to change portfolios as your investing goals transform.

Investors wanting a self-directed brokerage account should consider Stash or Robinhood to access stocks and ETFs of their choosing.

Robinhood

Robinhood offers most stocks and ETFs that trade on the US stock exchanges. Some exceptions can be OTC and ADR stocks with thin trading volumes and additional trading commissions.

Advanced investors can buy or sell options. A robo-advisor account isn’t available.

Stash

Stash lets investors buy most stocks and ETFs although it may not be possible to buy select stocks with low trading volumes or certain sector ETFs. But the investment selection is excellent for most investors.

It’s possible to browse stocks and funds by sector or investment theme.

The company also offers a Smart Portfolio robo-advisor with its middle and upper plans. This feature invests in stock and bond index funds proportional to the investor’s risk tolerance.

This platform can be the best option that want a portion of their portfolio in the managed Smart Portfolio and the rest in individual stocks and ETFs. Acorns only offers managed portfolios and Robinhood only provides self-directed accounts.

Research Tools

No platform offers in-depth research tools like a traditional online broker such as Fidelity, Schwab or Ally Invest. But investors can easily access basic information.

Acorns

Acorns doesn’t provide any research tools as investors can only invest in premade portfolios. Investors can read the ETF prospectus for each fund in their portfolio to understand how the fund can make money along with the potential risks.

Robinhood

The basic Robinhood membership offers these research tools:

  • Historical price chart
  • Analyst ratings
  • Quarterly earnings data
  • Recent market headlines

The numerous investment options but scant research tools may have you wonder if Robinhood is safe. It is, but other platforms may have better practices.

Robinhood Gold customers can read Morningstar research reports that can help investors make informed decisions. Active traders may also appreciate the Level II market data to see how much investors are willing to buy or sell their shares for.

Stash

Stash provides a basic price chart and news headlines for stocks and ETFs.

The Stash+ plan provides a monthly market insights report that provides analysis on the stock market and specific sectors. Overall, free stock analysis tools can be more effective.

Cash Management Accounts

All three platforms offer an FDIC-insured cash management account or an online checking equivalent. Being able to bank and invest with the same app can be a valuable convenience.

Each service requires opening an investment account before launching a banking account. Consider an app’s investment features before their banking options to choose the best one.

Acorns

The Acorns Checking account is only available with the two highest monthly plans. There are no additional fees and account features include:

  • “Smart Deposit” automated savings rules
  • Visa debit card
  • 55,000+ fee-free ATMs (Allpoint network)
  • Up to $250,000 in FDIC Insurance

The Smart Deposit savings feature can set aside a portion of each deposit to a savings goal. Doing so can prevent accidentally money you’ll need later.

You can also get free ATM withdrawals at over 55,000 locations across the United States and the world.

Another nifty feature is getting a tungsten metal debit card. It works like a traditional plastic card and can be an interesting conversation starter with friends.

Learn more about Acorns

Robinhood

The Robinhood cash management account is fee-free and can offer more banking perks than the other two apps.

Key account features include:

  • 75,000+ fee-free ATMs (Allpoint and MoneyPass networks)
  • Earn interest
  • Online bill payments
  • Up to $1.25 million FDIC Insurance

This account doesn’t charge any monthly service fees and comes with a Mastercard debit card. Two unique features include earning interest on the entire account balance and up to $1.25 million in FDIC Insurance.

Robinhood partners with several banks that each offer the $250,000 FDIC insurance limit by sweeping your uninvested cash to different institutions. Some of the partner banks include Goldman Sachs Bank, Citi®, HSBC Bank and Wells Fargo.

This account may not offer automated savings features or shopping rewards like Stash or Acorns but can be an exciting online banking option.

Learn more about Robinhood

Stash

A Stash banking account1 is available with every monthly plan. All Stash personal investing account holders are eligible to open a Stash Banking account with no overdraft fees, maintenance fees, or monthly balance fees, and there is fee-free ATM access4.

Account features include:

  • Automated savings tools
  • Stock-Back® debit card1
  • 55,000+ fee-free Allpoint ATMs4
  • Receive direct deposit up to two days early5
  • Banking services provided by Stride Bank, N.A., Member FDIC

Another automated feature is scheduling recurring investments.

All banking members can get a Stock-Back® debit card1. Switching to the Stock-Back® card can be worth it to earn back pieces of stock for stores you make purchases at. Stores without a publicly-traded stock can earn shares of an S&P 500 index fund.

Unique Features

It’s possible to earn passive income and park your uninvested cash into a rewards banking account. These unique perks can play a deciding factor in choose the best investing platform.

Acorns

Acorns can be one of the best options for a fully automated investing app. It can also be easier to earn shopping rewards than Stash.

Acorns Earn

The Earn features give members several options to earn bonus cash to invest. One way is to activate shopping offers at over 350 partners in the Acorns app and paying with a linked debit card or credit card.

A second option is installing the Chrome browser extension to shop online at over 12,000 brands.

Acorns deposits the cash rewards into the investing account and invests the balance when it reaches $5.

Spending Roundups

Another neat feature is rounding up debit and credit purchases to the next dollar and investing the round-up amount. The platform invests the roundups with a $5 balance but the Acorns debit card can instantly invest the round-up amount.

Stash also offers this feature but only for its Stock-Back Card®1.

Users can also set auto-deposit rules that routinely deposit cash into their investing account from a linked bank account.

Learn more about Acorns

Robinhood

Robinhood gives investors more control of the investment process but doesn’t offer the shopping rewards to get free stock unless you refer friends.

On-Demand Trading

Investors that don’t want to be restricted to certain trading windows will like Robinhood. It’s possible to place market-type orders during normal market hours and buy or sell positions at the current market price.

It’s also possible to place limit orders to only trade at or within a certain trading range.

Stash has two trading windows in the morning and two in the afternoon, for example. Acorns only offers ETF portfolios.

$1 Fractional Investing

Being able to buy stock and ETF shares with as little as $1 means Robinhood has the lowest investment minimum and there are no trade commissions or monthly service fees. The other platforms require a $5 balance which is also reasonable.

Robinhood Gold

Investors that want to trade using margin will need to upgrade to Robinhood Gold for $5 per month. The margin loan interest rates are lower than most brokerages.

Other Gold features include Morningstar research reports, Level II trading data and higher instant deposit amounts. Upgrading doesn’t provide interactive charts or technical analysis. Another free online broker is more likely to offer more robust charting tools and third-party analyst reports.

Learn more about Robinhood

Stash

Stash can be a good option for beginner investors because of its educational tools and Stock-Back® rewards program1.

Stock-Back® Card1

The Stock-Back® Card1 can be a great reason to choose Stash. The benefits of this Card can easily offset the monthly fee.

Most purchases earn 0.125% at select brands. For example, Amazon purchases earn Amazon stock and Starbucks trips can earn Starbucks stock.

Learning Library

All investors have access to the Stash Learn library that’s an online knowledge base covering investment basics. New investors can learn how stocks, ETFs and the stock market work.

Term Life Insurance

The bottom plan comes with $1,000 in term life insurance from Avibra6. Premium Stash+ members get up to $10,000 in coverage with an active subscription.

About Josh Patoka

After graduating in $50k with student loans in May 2008 from Virginia Military Institute with a B.A. International Studies and Political Science with a minor in Spanish (he studied abroad in Sevilla, Spain for 3 months), Josh decided to sell his soul for seven years by working in the transportation industry to get out of debt ASAP and focus on doing something else with a better work-life balance.
