Micro‑investing apps and full brokerages solve different jobs. One automates spare‑change deposits into a prebuilt portfolio.

Side‑By‑Side Specs
Acorns — What We Like / What We Don’t Like
✅ What We Like
- Round‑Ups grow a balance without thought; transfers occur when spare change totals $5, or instantly with real‑time Round‑Ups on the Acorns card.
- $5 recurring deposits keep money flowing, which suits smaller paychecks and new savers.
- Prebuilt ETF portfolios keep allocation on rails; Gold adds a custom slice up to 50% for names you pick.
- Simple plans: $3, $6, or $12 per month, with IRA and kids accounts available inside higher tiers.
- Emergency Savings and Checking post published APYs (variable) for stashing cash alongside investing.
⚠️ What We Don’t Like
- Flat monthly fees can dwarf small balances. At $1,000, $6/mo equals $72 per year (7.2%).
- Investment choice is narrow next to a full brokerage; even with custom slices you cap at half the portfolio.
- Bitcoin exposure is limited to a small ETF allocation, not direct coin trading.
Fidelity — What We Like / What We Don’t Like
✅ What We Like
- $0 commission on online U.S. stock and ETF trades; options are $0.65 per contract.
- Fractional shares start at $1, so you can buy by the dollar, not by the share.
- Every account in one place: brokerage, IRAs, 529 college savings, HSA, and more.
- Robo route when you want it. Fidelity Go charges 0% under $25k and 0.35% at $25k+ and adds coaching calls at that level.
- Recurring investments for stocks, ETFs, baskets, and funds make dollar‑cost averaging simple.
⚠️ What We Don’t Like
- Choice overload can slow a new investor who wants only “set and forget.”
- A small set of ETFs on the platform carries a transaction‑based service fee (up to $100), which can surprise those picks.
- Live coaching in Fidelity Go kicks in only once your balance hits $25k.
Acorns Or Fidelity: Which Fits You Better
Pricing & Packages
Acorns sells simple subscriptions. Bronze is $3 per month. Silver is $6 per month. Gold is $12 per month. Bronze includes automated investing and an IRA. Silver adds banking perks and live money Q&As. Gold adds kids investing (UGMA/UTMA) and a larger toolset. You pay the flat fee no matter your balance, so the effective percentage shrinks as your account grows. See the official Acorns plans & pricing for current details.
Fidelity’s self‑directed trades run $0 for online U.S. stocks and ETFs, with options at $0.65 per contract. There’s no account minimum for brokerage or IRAs. For automated management, Fidelity Go charges 0% for balances under $25,000, then 0.35% annually at $25,000 and up, and adds coaching calls at that tier. See the Fidelity Go advisory fee and pricing & fees.
Automation & Flows
Acorns is built around automation. Link your spending cards, and Round‑Ups move spare change into investing once the total hits $5 (or instantly when you use the Acorns debit card). You can also schedule $5 recurring deposits and let automatic rebalancing keep the portfolio on target. That combo makes momentum easy for anyone who struggles to set cash aside.
Fidelity offers recurring investments for stocks, ETFs, baskets, and funds, so you can schedule buys by amount and cadence without manual work. Dividend reinvestment is a click away. If you’d like the platform to manage allocation end‑to‑end, turn on Fidelity Go and let the robo handle rebalancing and cash flows.
Help & Onboarding
Acorns pushes clarity with a single app, a short questionnaire to set your risk mix, and one‑tap automation. Silver and Gold add live Q&A sessions to answer common money questions. If you want help for kids, Gold includes Acorns Early, which sets up UTMA/UGMA accounts for minors.
Fidelity’s footprint helps if you want many paths in one place. You can open a brokerage account now, add a Roth IRA later, and start a 529 when a child arrives—all inside one login. The robo path keeps things simple; the self‑directed path leaves nothing out. New investors can start with a tiny recurring purchase using fractional shares and build up from there.
Reporting & Attribution
Both show portfolio performance and holdings in clean dashboards. Acorns stays focused on the basics—allocation, value over time, round‑up history—so you aren’t lost in stats. Fidelity adds fund research, screeners, and deeper views when you need them. For tax time, each platform posts the standard 1099 package for taxable accounts, while IRAs keep reporting light unless you withdraw.
ℹ️ Good To Know: Monthly fees change the math at small balances. At $500, a $6/mo plan costs $72 per year (14.4%). By comparison, Fidelity’s self‑directed trades are $0, and Fidelity Go is $0 under $25k and 0.35% above that.
Facts referenced: Acorns plans ($3/$6/$12), Round‑Ups transfer threshold at $5, Custom Portfolio up to 50% of the mix, Checking/Emergency Savings APYs are published and variable; Fidelity $0 stock/ETF commissions and options at $0.65/contract, fractional shares from $1, recurring investments for stocks/ETFs, and Fidelity Go pricing. Official links are placed in the relevant sections above.
Price, Value & Ownership
Here’s the gap that matters: fixed fees make sense once your balance is larger, while percentage pricing favors small balances. Many buyers choose the tool that charges less at their current balance, then revisit later.

Decision Guide
✅ Choose Acorns If…
- You want automation to do the work—Round‑Ups and $5 recurring deposits fit your budget.
- You’d like an IRA inside a simple plan and you prefer a set asset mix.
- You want a single app that can add a kids account later under a flat monthly price.
✅ Choose Fidelity If…
- You want $0 online stock/ETF trades and the freedom to pick anything, including fractional shares from $1.
- You plan to add accounts over time—Roth IRA now, a 529 later, maybe an HSA at work.
- You want the option to toggle between self‑directed investing and a robo with coaching.
Best Fit For Most Starters
For new savers who want momentum without menus, Acorns is the easy choice. Round‑Ups make saving feel painless and $5 recurring deposits build the habit. Once your balance grows, take a fresh look at cost. If a flat fee no longer makes sense, Fidelity’s $0 trades and broad account lineup keep fees low while you scale.
For buyers who already know they want control and range, start with Fidelity. Schedule small recurring purchases using fractional shares, set dividend reinvestment, and add a robo when you need more structure. You can park an IRA, open a 529, and manage it all in one place. It’s hard to beat on long‑run cost when you’re self‑directed.
