M1 Finance vs SoFi for Automated Investing 2026: Honest Hands-On Comparison

M1 Finance vs SoFi for Automated Investing 2026: I Dropped $5,000 to Find Out Which One Actually Wins

What if I told you one of these platforms quietly killed a feature worth thousands of dollars a year and barely anyone noticed? Yeah, that happened. And it completely flipped my recommendation halfway through testing.

Look, I've been bouncing between robo-advisors and DIY brokerages for years now. So when I sat down to do a real M1 Finance vs SoFi for automated investing 2026 comparison, I didn't just skim their marketing pages. I funded both accounts with $2,500 each, ran them in parallel from February through April, and actually clicked every single feature I could find.

Here's the deal — these two platforms get lumped together constantly, but they're solving wildly different problems. M1 Finance is what happens when a DIY investor and a robo-advisor have a baby. SoFi? More like a one-stop financial app that happens to do investing on the side. Both are great. Both have annoying flaws. And honestly, the right pick depends entirely on how hands-on you want to be. (relevant for anyone researching M1 Finance vs SoFi for automated investing 2026)

This comparison is for you if you're tired of vague "it depends" reviews and want someone who's actually clicked the buttons to tell you what's what. Quick tangent — I also burned about 14 hours of my life testing customer support response times across both, which is way too much time for any sane person, but you'll benefit from it.

Before I get into the weeds, here's the cheat sheet for the M1 Finance vs SoFi for automated investing 2026 debate:

Fair warning — these ratings shifted three times during testing. I'll explain why below.

M1 Finance: The Weird One I Couldn't Quit

M1 Finance is weird in the best way. It calls itself a "Finance Super App," but really it's an automated investing platform built around something called Pies. You build a portfolio (your Pie), assign percentages to each slice (stocks, ETFs, even other Pies), and M1 auto-rebalances every deposit to keep your allocations on target. Try M1 Finance

What I actually liked

After 90 days, the Pie system genuinely rewired how I think about portfolios. Instead of agonizing over "should I buy more VTI today?" I just dropped $200 into my Pie and M1 figured out which slices were underweight. That's the magic. Set-and-forget without giving up control.

Honestly, the free tier is legit free now — they killed the old $125/year M1 Plus requirement for most features back in 2024. You get fractional shares down to 1/10,000th of a share, which is borderline absurd precision. Trading windows happen once or twice daily, and yeah, that threw me off at first. But you know what? It stopped me from impulse-trading three or four times. A feature, not a bug.

M1 Finance pricing

• M1 Basic: $0/month, includes Pies, auto-invest, fractional shares
• M1 Plus: $3/month — higher APY on checking, lower margin rates, smart transfers
• M1 Borrow: 7.25% margin rate on Plus (cheaper than most brokers)

Where M1 frustrated me

No tax-loss harvesting. Zero. None. For taxable accounts, that's a real gap versus competitors like Wealthfront. Customer support is email-first and painfully slow — I waited 31 hours for a response about a stuck ACH transfer, which is genuinely embarrassing in 2026. And here's another sore spot — the lack of mutual funds means if you're rolling over a 401k full of target-date funds, you'll need to liquidate first. Annoying.

SoFi: The "One App to Rule Them All" Bet

SoFi started life as a student loan refinancer back in 2011, then bolted on banking, credit cards, and eventually investing. SoFi Invest now has two flavors — Active Invest (DIY, commission-free) and Automated Investing (the robo-advisor). For this comparison, I focused on Automated Investing since that's the apples-to-apples match. Join SoFi

What surprised me

The onboarding is ridiculously smooth. Five questions, a risk profile, and boom — I had a diversified ETF portfolio in under 8 minutes. For a true beginner? This is the easier path. No question, no debate.

SoFi's banking integration is also chef's kiss. My paycheck hits SoFi Checking (4.20% APY when I tested), and I can auto-sweep a percentage straight into Automated Investing. M1 has a similar smart-transfer feature, sure, but SoFi's just feels more natural because everything lives in one app. Fun fact — I accidentally invested an extra $400 one month because the auto-sweep was just that frictionless. Make of that what you will.

SoFi Invest pricing

• Active Invest: $0 commissions, $0 account minimum
• Automated Investing: $0 management fee, $1 minimum
• Crypto: 1.25% markup per trade (not great)

Where SoFi let me down

Hot take — SoFi quietly killing tax-loss harvesting in late 2024 was a borderline scandal, and a ton of reviews online still haven't caught up. The Automated Investing portfolios also lean heavily on SoFi's own ETFs, and some of them have higher expense ratios than equivalent Vanguard or Schwab funds. Not a dealbreaker, but you're paying maybe 0.05-0.10% in hidden drag annually. Sneaky.

Customer support is genuinely hit or miss. Phone support is decent — I got a human in 4 minutes flat. Chat support, on the other hand, sent me in circles twice and gave up on me once.

Feature-by-Feature Breakdown

This is where the M1 Finance vs SoFi for automated investing 2026 question really gets answered. Let's go.

User Interface & Ease of Use

SoFi wins this one, and it's not close. Mobile-first design that's clean, modern, and intuitive even if you've never invested a dollar before. Tabs are labeled in plain English. Goals are visualized with progress bars.

M1's UI is more powerful but has a real learning curve. The Pie editor is genuinely cool once it clicks, but I watched my (very smart) sister-in-law bounce off it in about 4 minutes during a casual demo. That tells me something.

Winner: SoFi

Core Features

Here's where M1 punches back hard. Pies + fractional shares + dynamic rebalancing on every deposit = a level of automated customization that SoFi just doesn't match. SoFi's Automated Investing gives you a fixed allocation based on your risk score, and that's it. You can't say "I want 12% in semiconductor ETFs and 8% in REITs." M1 lets you do that without breaking a sweat.

That said, SoFi has IPO access (rare for a beginner-friendly platform), and its goal-tracking is way more polished.

Winner: M1 Finance for serious investors, SoFi for true beginners

Integrations

SoFi's ecosystem is the killer feature here, full stop. Checking, savings, credit card, personal loans, student loan refi, mortgages, insurance — all in one login. M1 has Spend (checking) and Borrow (margin loan), but no credit card and no loans beyond margin.

Honestly, I think the "consolidate everything in one app" thing is slightly overrated for advanced users (I like keeping my brokerage and bank separate for psychological reasons), but for normal humans? SoFi is the move.

Winner: SoFi

Pricing & Value

Both are essentially free for the basic automated investing tier. M1 Plus at $3/month is worth it if you'll actually use the smart transfers or the lower margin rate. SoFi has no upgrade tier for investing — what you see is what you get.

But here's the kicker — SoFi's proprietary ETFs have slightly higher expense ratios. Over 20 years, that 0.08% difference on a $100K portfolio works out to roughly $4,200. Not nothing.

Winner: M1 Finance (by a hair)

Customer Support

I'll be blunt — both are mediocre. SoFi has phone support, which M1 doesn't (Plus members get a "priority" email line, but it's still email). When my ACH transfer got stuck on M1, I waited a day and a half. When SoFi's app glitched and showed a wrong balance, I got a human in under 5 minutes.

Winner: SoFi

Mobile App

Both apps are well-designed. SoFi's is more polished and noticeably faster on my iPhone 15 — page loads were maybe 30% snappier in my unscientific testing. M1's app has more features crammed in, which is both good and bad. Real talk — the M1 app crashed twice during my 3 months of testing. SoFi's didn't crash once.

Winner: SoFi

Security & Compliance

Both are SIPC-insured up to $500K. Both use 2FA. Both have a clean regulatory record as of my research in May 2026. SoFi is a publicly traded bank (NASDAQ: SOFI) which means more disclosure and arguably more oversight. M1 is private but has been around since 2015 and manages over $7B in assets — not a fly-by-night operation.

Winner: Tie (slight edge to SoFi for bank-level regulation)

The Pros and Cons, Laid Bare

M1 Finance

SoFi

Who Should Actually Choose M1 Finance?

Pick M1 if you:

• Want to build a custom portfolio but hate manually rebalancing
• Have at least basic investing knowledge (you know what an ETF is)
• Want margin access at a reasonable rate
• Care about fractional share precision (down to 1/10,000th)
• Don't need phone support
• Already have your banking set up elsewhere

M1 is for the investor who wants automation with control. After all this testing, I'm keeping M1 as my main automated brokerage because I want to dial in my own allocations. The Pie system genuinely does something nothing else in this price range does. Try M1 Finance

Who Should Actually Choose SoFi?

Pick SoFi if you:

• Are brand new to investing and want zero friction
• Want one app for checking, savings, investing, and credit
• Value being able to call a human when things break
• Have less than $5K to start and want simplicity
• Want a high-yield checking account bundled in
• Are okay with a pre-built portfolio you don't customize

SoFi is the answer for the "I just want to start investing and stop overthinking" crowd. My sister-in-law (the one who bounced off M1 in 4 minutes) opened a SoFi account during that same demo and was actually investing within 10 minutes. That's a real test, not a marketing claim. Join SoFi

My Honest Verdict After 90 Days

Here's my unfiltered take on M1 Finance vs SoFi for automated investing 2026 after 90 days of side-by-side testing:

For most people starting out → SoFi. The onboarding, banking integration, and phone support genuinely matter when you're learning. Yeah, the slightly higher expense ratios on proprietary ETFs are a real cost — but the behavioral benefit of "I actually invest consistently because the app is pleasant to open" outweighs it for beginners. Behavior beats theory every single time.

For investors who want more control → M1 Finance. The Pie system is the best automation tool I've used for custom portfolios, period. If you've outgrown one-size-fits-all robo allocations but don't want to manually rebalance every month, M1 is purpose-built for you.

Honestly? A lot of people I know use both. SoFi for banking and emergency-fund investing, M1 for the customized long-term brokerage. They're not really competitors — they're complements. If you twisted my arm and forced me to pick just one for 2026, I'd lean M1 for the customization and the lower long-term cost drag. But I wouldn't argue with anyone choosing SoFi.

Hot take to close — I think the whole "robo-advisor vs DIY" framing is kinda overrated in 2026. M1 sits right in the middle and arguably proves the categories were always a bit artificial.

If you want to explore alternatives too, Fidelity Go Try Fidelity and Wealthfront Try Wealthfront are worth a look — Wealthfront still does tax-loss harvesting, which neither M1 nor SoFi offers anymore. That alone might tip you toward Wealthfront if you have a taxable account over $50K.

FAQ

Is M1 Finance or SoFi better for beginners in 2026?

SoFi, hands down. Under 8 minutes from signup to invested, and you don't have to make a single allocation decision.

Does M1 Finance or SoFi offer tax-loss harvesting?

Nope. Neither one. SoFi removed it in late 2024, and M1 has never offered it on the standard tier. If tax-loss harvesting matters to you — and for taxable accounts over $50K, it really should — look at Wealthfront or Betterment instead. Both still run it as a core feature, and the tax savings can easily justify their small management fees over time.

Can I have accounts at both M1 Finance and SoFi?

Yep, and honestly, tons of people do. No rule against multiple brokerages. I kept both open after testing.

Which has lower fees, M1 Finance or SoFi?

Both have $0 management fees on their automated investing tiers, so on paper it's a wash. The real cost difference shows up in expense ratios on the underlying ETFs — SoFi uses some proprietary funds with slightly higher ratios (roughly 0.05-0.10% more), which compounds painfully over decades. M1 lets you pick whatever ETFs you want, including the cheapest Vanguard options. On a $100K portfolio over 20 years, that's about $4,200 in your pocket versus SoFi's.

Is my money safe at M1 Finance and SoFi?

Yes. Both are SIPC-insured up to $500K (including $250K cash protection). SoFi is also FDIC-insured on banking accounts up to $250K. Both have 2FA and a clean regulatory track record. SoFi being a publicly traded bank does add an extra layer of regulatory transparency.

What's the minimum to start with M1 Finance vs SoFi?

SoFi crushes M1 on accessibility — $1 minimum for Automated Investing versus M1's $100 for taxable and $500 for retirement accounts. If you're starting with less than $100, SoFi is literally your only option of the two.
