The Verdict Up Front

Choose Acorns if: You want completely hands-off investing, struggle to save consistently, need “forced savings” through Round-Ups, prefer managed portfolios, or want IRA matching (1-3%)

Choose Stash if: You want to learn investing, prefer choosing your own stocks/ETFs, need extensive educational content, value flexibility, or want Stock-Back® rewards earning fractional shares


Fundamental Difference: Full Automation vs Guided Learning

Acorns: The “Set It and Forget It” Approach

As a robo-advisor, Acorns simply has 5 pre-built expert portfolios—comprised of low-cost ETFs—based on one’s risk tolerance, allowing you to be completely hands-off in your investing

How Acorns Works:

  1. Answer risk tolerance questionnaire
  2. Acorns assigns you to Conservative/Moderate/Aggressive portfolio
  3. Portfolio consists of 5-7 ETFs (no individual stocks)
  4. Cannot pick or change individual holdings
  5. Automatic rebalancing quarterly
  6. Round-Ups automate investing from purchases

Philosophy: Zero decisions required after setup

Stash: The “Learn and Choose” Approach

Stash is not a true robo-advisor. Stash allows you to invest in individual stocks and a small handful of ETFs of your choosing

How Stash Works:

  1. Choose between DIY investing or Smart Portfolios
  2. DIY: Pick from 4,000+ individual stocks and ETFs
  3. Smart Portfolios: 4 automated ETF “Diversified Mixes” from iShares (AOR, AOK, AOA, AOM)
  4. Themed investments (e.g., “Clean Energy,” “Tech Giants,” “Delicious Dividends”)
  5. Fractional shares available
  6. Educational content guides decisions

Philosophy: “We’re driven to help you learn and take control”

Key Difference: Acorns makes ALL investment decisions for you. Stash teaches you to make your own (but offers Smart Portfolios if you want automation too).


Pricing and Fees: Similar But Different

Fee Structure Comparison

Both charge flat monthly fees, making comparison straightforward

Acorns Pricing:

  • Bronze: $3/month = $36/year (Invest + Later + Checking)
  • Silver: $6/month = $72/year (+ 1% IRA match)
  • Gold: $12/month = $144/year (+ 3% IRA match + Early kids accounts)

Stash Pricing: Stash Growth costs $3 a month, while Stash+ costs $9 a month—over the course of a year, Stash Growth would run you $36, while Stash+ will end up costing $108

  • Stash Growth: $3/month = $36/year (was formerly $3, now entry tier)
  • Stash+: $9/month = $108/year (premium tier with kids accounts)
  • Note: $1/month “Beginner” tier discontinued in most markets

Winner on Cost: Acorns wins slightly—$36/year (Bronze) vs $36/year (Stash Growth) are tied, but Acorns Gold at $144/year beats Stash+ at $108/year when factoring in IRA matching

ETF Expense Ratios

Acorns:

  • 0.03-0.25% for most ETFs
  • Bitcoin ETF: 0.95%
  • Average: ~0.15%

Stash: As of the time of writing, the annual expense ratios of Stash’s various ETF options range from 0.03% to 0.95%

  • Similar range: 0.03-0.95%
  • Smart Portfolio “Diversified Mixes” (iShares ETFs): Likely 0.15-0.25%
  • Averagelikely slightly higher than Acorns

Total Cost Analysis

At $1,000 Balance:

  • Acorns: $36 + $1.50 (0.15% ER) = $37.50/year (3.75%)
  • Stash: $36 + $2.00 (0.20% ER est.) = $38/year (3.8%)
  • Winner: Acorns (slightly)

At $10,000 Balance:

  • Acorns: $36 + $15 = $51/year (0.51%)
  • Stash: $36 + $20 = $56/year (0.56%)
  • Winner: Acorns

At $25,000 Balance:

  • Acorns: $36 + $37.50 = $73.50/year (0.294%)
  • Stash: $36 + $50 = $86/year (0.344%)
  • Winner: Acorns
