Acorns Vs Stash | Fees Most Buyers Miss

For micro‑investing, choose Acorns if you want autopilot ETFs; pick Stash if you prefer stock choice with a flat fee and optional robo.

Micro‑investing apps help new savers put cash to work without juggling brokers, funds, and transfers. Acorns leans toward automation, while Stash leans toward choice. This guide gives you the fast verdict, the fees that change the math, and clear trade‑offs so you can pick with confidence.

In A Nutshell

Pick Acorns if you want a set‑it‑and‑forget‑it portfolio that invests spare change and recurring deposits into diversified ETFs. Pick Stash if you want to pick individual stocks or ETFs, with an optional “Smart Portfolio” that automates things when you want a break.

Both charge flat monthly fees. Stash adds an extra 0.25% a year on assets in its managed Smart Portfolio once that balance is at least $1,000; Acorns’ managed portfolios don’t tack on an extra advisory percentage.

Acorns — What We Like / What We Don’t Like

✅ What We Like

  • Round‑Ups turn everyday purchases into steady investing; money moves once your spare change reaches $5.
  • Clear tiers: Bronze $3, Silver $6, Gold $12, with IRAs on all tiers and family tools on Gold.
  • Hands‑off ETF portfolios with automatic rebalancing; no extra advisory percent stacked on top of the flat fee.
  • Gold unlocks “Custom Portfolios” so you can add individual stocks without leaving the app.
  • Option to allocate a small slice to a Bitcoin‑linked ETF inside a diversified mix (capped).

⚠️ What We Don’t Like

  • Flat fees can weigh on small balances; a $3 plan is $36 a year whether you hold $200 or $2,000.
  • Stock picking is limited to the Gold tier; Bronze and Silver keep you inside ETF portfolios.

Stash — What We Like / What We Don’t Like

✅ What We Like

  • Pick individual stocks and ETFs with fractional shares; add Smart Portfolio when you want automation.
  • Two clear prices: Growth at $3 and Stash+ at $9 per month.
  • Stash+ boosts the Stock‑Back® card to 1% in stock on every swipe (up to $1,000 in spend each month).
  • Custodial accounts for kids are part of Stash+.

⚠️ What We Don’t Like

  • If you turn on Smart Portfolio and your robo balance is $1,000 or more, Stash adds a 0.25% annual fee on top of the flat fee.
  • To get kids’ accounts and boosted card rewards, you need the higher‑cost Stash+ plan.

Acorns Or Stash: Which Fits You Better

Automation & Flows

Acorns is the king of “set it and forget it.” The Round‑Ups system pulls in spare change by rounding purchases to the next dollar and invests once it hits $5. Recurring deposits and paycheck split keep the engine running with little effort.

Stash can automate two ways: scheduled Auto‑Stash transfers, or a Smart Portfolio that invests for you. That automation is optional, so you can flip between DIY and managed investing as your needs change. The catch: Smart Portfolio adds 0.25%/yr once your managed balance reaches $1,000.

Segmentation & Personalization

Stash lets you express preferences through individual stocks and themed ETFs, with fractional shares so small deposits still buy a slice. Stash+ sweetens card rewards for stock on spending, which nudges frequent card users toward the higher tier.

Acorns builds a diversified ETF mix based on your inputs. If you want some control, the Gold tier adds “Custom Portfolios,” which lets you add selected stocks or ETFs alongside the core mix.

Integrations & APIs

Both link to U.S. banks for transfers. Acorns’ banking integrates Round‑Ups and offers ATM access and savings APY in higher tiers. Stash’s banking centers on the Stock‑Back® card that turns swipes into positions in your portfolio.

Reporting & Attribution

Each app gives performance charts, cost basis, and tax docs for taxable and retirement accounts. Stash’s DIY side surfaces position‑level detail for stock pickers, while Acorns leans on portfolio‑level clarity for long‑term goals.

Deliverability & Compliance

Both firms are tied into the standard U.S. investor protections. Brokerage accounts are covered by the Securities Investor Protection Corporation (SIPC) up to $500,000 total, including $250,000 for cash; this does not protect against market losses. You can read the official coverage rules here: SIPC protection details.

They’re also bound by SEC rules for robo‑advisers and investment advisers. If you want a plain‑English explainer, the regulator’s bulletin is a good starting point: SEC’s investor bulletin on robo‑advisers.

Pricing & Seats

Acorns now offers three bundles: Bronze at $3/month, Silver at $6/month, and Gold at $12/month. IRAs are included across tiers; family tools, kids investing, and custom portfolio features live in Gold.

Stash sells two plans: Growth at $3/month and Stash+ at $9/month. If you enable Smart Portfolio and the managed balance is at least $1,000, a 0.25% annual advisory charge applies in addition to the flat fee. Kids’ custodial accounts and boosted card rewards sit in Stash+.

Help & Onboarding

Both apps guide new investors through goal setup and risk questions. Stash appeals to users who enjoy browsing ideas and hand‑picking positions. Acorns appeals to users who want guardrails and fewer decisions from day one.

ℹ️ Good To Know: If you plan to use Stash’s Smart Portfolio, include the 0.25%/yr advisory charge on managed assets of $1,000 or more when you budget. Flat monthly fees are only part of the total.

Price, Value & Ownership

Factor Acorns Stash
Base Flat Fee (monthly) $3 / $6 / $12 $3 or $9
Advisory % (if robo) None; included in bundle 0.25%/yr on Smart Portfolio ≥$1k
ETF Expense Ratios Applies inside portfolios (varies by fund) Applies to ETFs you own (varies by fund)
Rewards & Matches Retail bonus investments; matches on higher tiers Stock‑Back on card; 1% on Stash+ up to monthly cap
Safety Net SIPC on brokerage; FDIC on checking deposits via bank partners SIPC via Apex on brokerage; FDIC sweep for uninvested cash

If you keep balances small, flat fees loom large; if you plan to rely on Stash’s Smart Portfolio, add the 0.25% to get your real annual cost.

Best Fit For Most Savers

Start with Acorns if you want a low‑friction path that moves money into a diversified portfolio without tinkering. The Round‑Ups engine and flat pricing keep choices light. If you enjoy browsing ideas and buying shares of companies you know, start with Stash Growth. Add Smart Portfolio only if you want automation and are comfortable with the added 0.25% on managed assets of $1,000 or more.
