Stash charges $3/month and combines a fractional share brokerage, IRA account, and banking with Stock-Back rewards in a single app. Unlike Acorns (which uses round-ups and a hands-off portfolio), Stash lets you choose your own ETFs and individual stocks from a curated selection. It is aimed at beginner investors who want to build knowledge while building a portfolio. The $3/month fee is the same as Acorns and M1 Premium, making the comparison between these apps a question of features rather than price.

Stash Fees: $3/Month Explained

Like Acorns, Stash charges a flat $3/month = $36/year for all features. There is no tiered pricing:

Portfolio Size Annual Fee As % of Portfolio
$500 $36 7.2%
$1,000 $36 3.6%
$5,000 $36 0.72%
$14,400 $36 0.25% (break-even vs Betterment)
$25,000 $36 0.14%
$50,000 $36 0.07%

Above $14,400, Stash costs less in absolute dollars than Betterment (0.25%). But Betterment offers tax-loss harvesting, goal planning, and a more polished platform at that balance level.

Plus underlying ETF expense ratios — Stash’s fund selection includes ETFs with expense ratios of 0.03–0.50%, depending on your choices. The ETFs you pick matter; some “theme” ETFs carry higher costs.

Investment Options: What You Can Buy on Stash

Stash offers a curated selection of 300+ investment options including:

ETFs by theme:

  • “Clean & Green” (clean energy ETF)
  • “American Innovators” (technology ETF)
  • “Do the Right Thing” (ESG ETF)
  • “Roll With Buffett” (Berkshire Hathaway focus)
  • Standard index ETFs (S&P 500, total market, international)

Individual stocks:

  • Large-cap US stocks (Apple, Amazon, Microsoft, etc.)
  • Fractional shares available — invest any dollar amount

IRA selections: Same universe of ETFs and stocks available inside Roth and Traditional IRAs.

The themed ETF branding is Stash’s way of making investing approachable for beginners who might not know what a “total stock market ETF” is, but understands “Clean Energy.”

Stock-Back Rewards: Stash’s Key Differentiator

Stock-Back is Stash’s debit card rewards program:

  • Every purchase with the Stash debit card earns fractional shares
  • Brand-specific rewards: spending at Nike earns Nike stock; spending at a grocery store earns a grocery index ETF
  • Rate: typically 0.125% of your purchase (lower than top cashback cards)
  • No annual fee beyond the $3/month Stash subscription

Example: You spend $500/month on the Stash card. At 0.125%, you earn $0.625 in stock per month = $7.50/year in fractional shares.

This is a meaningful engagement tool — watching your fractional shares accumulate creates investment habit — but the financial value is modest compared to a 2% cashback credit card.

No Round-Ups: Key Difference From Acorns

Unlike Acorns, Stash does not offer round-up investing. If you want spare change automatically invested after every purchase, Acorns is the better choice. Stash’s equivalent is its Auto-Stash feature: automatic recurring deposits on a schedule you set (weekly, bi-weekly, monthly). This is less automatic than Acorns’ round-ups but more predictable.

Stash IRA Accounts

Stash includes Roth and Traditional IRA accounts in the $3/month plan:

Account 2026 Limit Fee
Roth IRA $7,000 ($8,000 age 50+) Included in $3/month
Traditional IRA $7,000 ($8,000 age 50+) Included in $3/month

Unlike Acorns (which auto-selects a portfolio for your IRA), Stash lets you choose your own funds inside your IRA — the same curated ETF and stock selection available in taxable accounts.

Stash vs Acorns vs Betterment

Stash Acorns Betterment
Fee $3/month $3/month 0.25%/yr
Portfolio control Yes (curated) No No (risk score)
Round-ups No Yes No

Who Stash Is Best For

Strong match:

  • Beginners who want to learn about individual stocks and ETFs while investing small amounts
  • Those who prefer choosing their own investments vs. a fully automated portfolio
  • Users who want Stock-Back debit rewards on everyday spending
  • Investors who want Roth or Traditional IRA with stock-picking ability at $3/month
  • Parents who want custodial accounts for children

Consider alternatives if:

  • You want round-up investing → Acorns
  • Your balance is above $14,400 and you want tax-loss harvesting → Betterment or Wealthfront
  • You want $0 fee → Fidelity Go (IRA under $25K) or M1 Finance Basic
  • You want a fully automated hands-off portfolio → Betterment
