Stash offers a suite of financial tools available to anyone who signs up for a subscription; investing automatically is one of the pieces. Launched in 2015, Stash is an all-digital offering for financial services aimed squarely at younger investors to help them spend, save, and invest wisely. It has a user-friendly interface and is more geared towards saving and spending than investing. It offers what are called Stock-Back® rewards that allow you to earn shares of stock or ETFs when you make purchases with a Stash debit card1.

New and Notable Updates

  • Every Thursday, Stash holds a "Stock Party" on Twitter for its customers at 4pm ET. The "Stock Party" events have drawn 7,000-18,000 people most weeks.
  • Stash joined FINTECH IN ACTION (FIA) and the Fintech Equality Coalition to promote Black inclusion in finance and fintech. 
  • A new feature, Diversification Analysis, calculates the Client’s overall portfolio diversification and encourages the Client to diversify further to reduce risk.

Key Takeaways

  • Stash services and features available depend on the clients' subscription level and monthly fee.
  • Clients are encouraged to choose an investing theme, which may result in higher management fees for the underlying ETFs.
  • Debit account with "Stock-Back."

  • Excellent educational resources.

  • Automatic savings and investment tools.

  • No tax-loss harvesting.

  • No automatic rebalancing.

  • Debit account doesn't earn interest.

Stash offers bank accounts1 through Green Dot Bank plus digital advisory services through Stash Investments LLC. Stash has a tiered account structure, costing $1-$9 per month. For the Beginner tier, investors pay $1 per month for a taxable investment account, debit account access, the ability to earn Stock-Back, plus free financial education. A Growth account, for $3 per month, offers everything in the Beginner tier plus the ability to plan for retirement and open an IRA. A Stash+ account, for $9 per month, also adds investing accounts for children (Uniform Gifts to Minors Act (UGMA) and Uniform Transfers to Minors Act (UTMA) accounts), as well as a debit card and a monthly market insights report.

Stash’s ETF universe includes thematic offerings focused on companies involved in emerging technologies like blockchain and digital security, gaming, robotics, and social media in addition to regional focuses, socially responsible options, and more traditional themes. Some of the exchange-traded funds (ETFs) with thematic focus have fees that are on the higher end—although this reflects how targeted some of them are. Apex Clearing Corporation provides clearing and execution services and serves as a custodian for advisory assets of Stash clients.

Account Setup


Stash is focused on the beginner investor. You need to create a Stash account and then the Stash Coach app guides you through the onboarding process, asking a series of questions that collect your personal details along with a choice between conservative, moderate, and aggressive risk tolerance. Life status, net worth, and other income data complete your profile. As part of account setup, you create a taxable investment account before setting up a debit account through Green Dot Bank.

Prior to account setup, you can play with some broad tools, but these are mostly in the form of measuring the impact of increased funding on a portfolio assumed to grow 5% a year. That said, you can still view the investment offerings through Stash in detail prior to giving over your email. Stash goes the extra step of gathering together useful links and information on a secondary landing page for each listed offering.

As part of your account setup, you pick one of six specific themes that include “Emerging international up and comers” and “Companies with a conscience,” but you need to be aware that thematic filtering will limit investment choices. You can reject Stash’s “curated suitable investment” list and choose limited alternatives but the system may respond with reasons the alternatives might be inferior to the proposed list—whether socially-responsible, thematic, or traditional. Portfolio recommendations may change after funding if you edit the answers used to create your profile.

Stash supports individual, retirement, and custodial accounts but no joint accounts. The account minimum is $0 but the $1 per month (individual) and $3 per month (retirement through a Growth account) minimum payments will result in very high fees in relative terms until the account balance is high enough to bring that under industry averages.

Goal Setting


Stash’s goal setting and tracking tools are geared towards young investors just getting started. The Stash Coach app directs you to a wide assortment of broad-brush educational and “how-to” articles through the Stash Learn portal while the account interface includes rudimentary analysis tools that include “Potential” and “Idea” sections. Beyond the digital resources and tools, you are on your own after setup, as Stash doesn’t offer the ability to consult with a financial advisor at all.

This lack of a human advisor is covered well by the digital helper in the form of Stash Coach. Stash Coach is organized as a game where you earn points and attain higher levels after completing investment and learning challenges. Gamifying investment will likely appeal to young investors, but older clients may not like the interface—especially when looking for quick advice.

The content through Stash Coach is tailored to your client profile, meaning that you see different articles and get different tasks if you are conservative in nature as opposed to aggressive or moderate. The weekly challenges are meant to expand your investment knowledge and awareness of the range of funds that Stash offers. There are also tasks that relate to your account funding, rewarding you for turning on Auto-Stash or going for a number of months without selling investments. This could be construed as benefiting Stash as much as you, but the end result is more funds going into your portfolio and staying there. 

Account Services


Deposits to your investment account require logging in and making a request that’s sent to a linked bank or setting up recurring deposits on a weekly, biweekly, or monthly basis. Withdrawals are requested through the same interface but it takes up to five business days to receive funds. Stash accounts do not use margin and there is no bill paying service available.

Cash Management

Stash provides banking services that can work with investments through Stock-Back®. The Stash debit account includes thousands of free ATMs2 and no hidden or overdraft fees3. However, it pays no interest, unlike cash in the investment account. Instead, your purchases earn “Stock-Back®” rewards that automatically add fractional shares of the retailer or retailer’s parent if the company is publicly traded and on Stash’s list of over 450 stocks and ETFs. Rewards from your other purchases buy fractional shares of Vanguard Total World Stock ETF, which carries a low 0.09% expense ratio4.

You can fund your debit account via direct deposit, free cash in the investment account, or through a transfer from a linked bank account. If you have your paycheck set up to be deposited directly to your bank account through the ASAP Direct Deposit feature, Stash gives you access to your cash up to 2 days early. You can also fund the account by depositing the cash at participating retailers, but they can charge up to $4.95 per transaction and funding is capped at $2,500 per day. The maximum balance you can have in your bank account at any time is $50,000.

Portfolio Construction


According to disclosures, Stash’s investment advice is primarily based on the following principles:

  • Equities as an asset class
  • Passive investing
  • Fixed-income assets hedge portfolios
  • Diversification
  • Investment advice adjusted for emotional bias and personal beliefs

Stash’s robo-advisor picks your portfolio contents from a pool of about 2,500 S&P 500 components and approximately 60 exchange-traded funds, which is a wider universe than most robo-advisors use. Potential investments are added to the list if they pass the criteria established in "The Stash Way," which is focused on long-term growth. The ETF list has been relabeled with socially-conscious and other thematic titles, like “All That Glitters” for a precious metals fund and “Water The World” for a water resources fund. The thematic titles are friendlier for new investors and certainly make it easier to understand what the fund is about if it is your first time seeing sector level ETFs.

However, many of the listed ETFs carry high expense ratios that aren’t well disclosed, potentially incurring hidden costs. Also, the thematic labels carry over to the listing of your portfolio holdings through account interface rather than the actual underlying securities or tickers. This is usually a moot point with robo-advisors, as investors looking for a robo-advisor to take on the responsibility of handling their investments don’t often feel the need to double-check the algorithm’s diversification and allocation strategy, but it becomes an issue with Stash that we’ll address as part of portfolio management. 

Portfolio Management


This is the weakest piece of Stash's offerings, and with its focus on new investors, generates numerous red flags in our book. Why? Stash basically leaves portfolio management up to you. There is no automatic rebalancing or tax impact considerations. Stash curates a list of stocks and ETFs that its clients can use to build a portfolio, but beyond that, it's up to you. Stash states that it doesn’t rebalance portfolios “or otherwise manage Stash Accounts for Clients on a discretionary basis.” The Stash Coach recommends investments for you, but you will ultimately be responsible for addressing the issues (or not).  

In August 2020, Stash added a new tool called Diversification Analysis to its app and website. Diversification analysis is available to any Stash customer with an investing account, and it is designed to guide you through the process of crafting a more diversified portfolio. The tool takes three pieces of information to analyze your portfolio and calculate a diversification score: your risk profile, the appropriate asset allocation given your risk level, and your current portfolio. It generates a score displayed on a bar indicating whether your portfolio is diversified or not.

When you click on, “View analysis breakdown,” the tool will list four different investment categories Stash considers, plus the target percentage of assets for each, based on your risk tolerance. These four categories are U.S. companies, foreign companies, up and coming (emerging) markets, and bonds. The categories will remain the same for everyone, but the allocation will change based on your risk profile. The screen will then highlight which categories need attention, but the action is left up to you. Trades are queued up and executed during four trading windows when markets are open.

The younger client base Stash is after may not understand this front-end approach, instead, expecting the robo-advisor to keep a watchful eye on their investment positions. Stash’s performance information is limited to historical data on individual securities, making it impossible to compare the resiliency of Stash’s approach with rivals who disclose sophisticated and detailed methodologies. In the absence of all this, Stash is putting a lot of expectations on the beginner investor to learn quickly while at the same time asking them to trust a process that isn’t disclosed to a level an experienced investor would be comfortable with.   

Finally, dividend reinvestment is mandatory for retirement accounts and is available for individual taxable accounts. Stash has a program called DRIP, where customers can automatically reinvest dividends across STASH's suite of investment products, including personal brokerage, traditional & Roth IRA's and custodial accounts.

User Experience


Desktop Experience

The website contains a handful of links that highlight major account features, explain services, and disclose legal requirements. Many features are geared toward young investors, with references to social media and the “budding legal marijuana industry.” Stash admits that 84% of its clients are beginners and the website addresses their needs with a simplified approach to financial planning and communications.

The tools themselves are fairly simple, but anyone wanting to dig deeper is in for long-winded, poorly-written, and purposely dense text in the disclosures, forcing the majority of new and prospective clients without law degrees to fall asleep or give up. For example, reading the advisory agreement requires slogging through 40 pages of small print, with over 19,000 words and no table of contents. A new client, unsure of how investing works, is unlikely to make the effort.

Mobile Experience

The website is mobile-ready and Stash provides mature iOS and Android apps that have garnered good reviews and provide the option of two-factor authentication. Stash was, of course, originally launched through a mobile-only platform and has grown to offer web-based account management. One drawback from this is that the desktop experience is not as full-featured as the mobile app. Some features, such as debit card use, are available on the mobile app only. 

Customer Service


Stash provides you prompt customer service, for the most part. The contact link triggers a drop-down menu with an entry form that searches the available FAQs for potential answers. Beyond that, an email address and phone number are provided at the bottom of most web pages and in the FAQ. Customer service hours are not listed on the website, but in direct queries to the company we are told that the hours are Monday through Friday from 9 AM to 5 PM Eastern time. Several phone calls during market hours achieved contact with a representative within two minutes. Customer service representatives can be contacted via direct message on Twitter and Facebook Messenger.

However, there’s no live chat and the FAQ omits key information, including a description of the management interface and the advice—or lack thereof—received after account setup. There are no financial advisors available for Stash customers who need more help.

Education & Security


Stash offers its educational materials for free through the Stash Learn section. The Stash Learn section is impressive, with dozens of articles divided into logical investment and planning topics that include retirement, vacation, parenting, career, and income. This section also features numerous podcasts as well as tutorials on using the Stash platform, with many how-to articles that are also accessible through the FAQ. All of the content reviewed was well-written in plain language—a plus for the beginner demographic. The premium investment account comes with additional marketing commentary and content beyond what is offered in the lower tier accounts.

Stash’s security is sufficient and comparable with peers. Stash uses 256-bit SSL encryption and follows industry standards for data security and access control. Apex Clearing holds your funds, providing access to Securities Investor Protection Corporation (SIPC) insurance and excess insurance. Green Dot Bank, which provides banking services, has FDIC insurance on the cash held in accounts.

Commissions & Fees


Stash used to charge a flat 0.25% wrap fee annually for advisory services, with a $1 minimum per month for taxable accounts and $2 for retirement accounts. This changed in August 2019 to a tiered structure with $1 a month for a taxable account (Beginner), $3 per month for a retirement account (Growth) and $9 a month for all that plus Uniform Gifts to Minors Act (UGMA) and Uniform Transfers to Minors Act (UTMA) accounts. All of these accounts (except retirement only) come with the aforementioned debit account service as part of them. Apex charges $75 to transfer the account to another broker. Wire transfers are not available.

There are some important points to keep in mind to understand Stash’s fee structure. The main one is that you will incur management fees charged by ETFs after purchase. As mentioned, the ETF list includes many securities with high expense ratios, so this is a layer of fees outside of Stash’s direct service that you should keep in mind.

More importantly, a fee of $1- $3 per month is actually much larger percentage-wise on small accounts than the assets under management wrap fee approach at other robo-advisories. For example, $12 annually on a $1000 is 1.2%. If you look at that number in comparison with a service that offers tax-loss harvesting and automatic rebalancing for 0.5% annually ($5), you see that the smaller account minimum comes at a cost for beginners. With $5000 in a Beginner account, Stash is a competitive 0.24% annually, but has fewer automated portfolio management tools. 

  • Monthly cost to manage a $5,000 portfolio: $1, $3, or $9
  • Monthly cost to manage a $25,000 portfolio: $1, $3, or $9
  • Monthly cost to manage a $100,000 portfolio: $1, $3, or $9

Is Stash a Good Fit For You?

Stash's simplified approach to getting new investors started with an app that lets you track spending and saving, while giving you access to buy stocks with rewards points, is unique and effective. Its educational content is useful and appropriate for new to moderately experienced investors.

Stash makes money through monthly subscription fees while touting no hidden costs but the affiliated Stash Capital broker-dealer benefits from client order flow, securities lending, directing transfers from debit to investment accounts, and FDIC-insured overnight cash sweeps. These hidden fees come directly from clients' pockets, building mistrust that can be overcome with a few tweaks in company policy and full disclosures that can be understood by the average client.

The Review Process

To evaluate these platforms, we sent questionnaires with over 100 queries to the participating robo-advisories. Most of the companies we reviewed gave us socially-distanced video demonstrations of their platforms and services during August 2020.

From the questionnaires, the hands-on testing of the platforms, and the platform demonstrations, we scored each category and then combined the category scores into an overall rating for each robo-advisor. Each category covers the critical elements users need to thoroughly evaluate a robo-advisor.
