Best Robo-Advisors and Brokerage Accounts for Passive Investors in 2026: Betterment vs. Wealthfront vs. Fidelity vs. Schwab

The Real Cost of “Free” and When to Move Past Your Savings Account

A $25,000 portfolio in Schwab’s “free” robo-advisor costs you roughly $75 to $150 more per year than Betterment or Wealthfront charge in actual advisory fees. That’s not speculation. It’s math derived from Schwab’s own mandatory cash allocation, the same cash allocation that led to a $187 million SEC settlement in 2022 for misleading clients about hidden costs.

If you’ve been parking cash in a high-yield savings account while the Fed holds rates at 3.5 to 3.75% for three consecutive meetings, you’re probably earning somewhere around 4.2% to 5.0% APY with zero risk. That’s a fine deal for your emergency fund. But once you’ve filled that bucket (three to six months of expenses, held somewhere safe and liquid, as we covered in our best high-yield savings accounts guide), the question becomes: where does the next dollar go?

I’ve spent several weeks running the numbers across Betterment, Wealthfront, Fidelity Go, and Schwab Intelligent Portfolios, cross-referencing fee structures from Bankrate, NerdWallet, and Morningstar’s 2025 Robo-Advisor Report. What follows is the comparison I wish someone had handed me before I made my own first move out of a savings account.

The Fee Math Nobody Shows You (in Actual Dollars)

Percentages are abstract. Dollars are not. Here’s what each platform actually costs at four common balance tiers, including both the advisory fee and the underlying fund expense ratios that every article mentions but nobody adds up.

At $10,000:

  • Betterment: $25 advisory + $4 to $17 in fund ERs = $29 to $42/yr. Important catch: balances under roughly $24K that don’t meet the $250/month auto-deposit trigger pay a flat $5/month instead, which is $60/yr. On a $10K balance, that makes Betterment one of the more expensive options despite the 0.25% headline rate.
  • Wealthfront: $25 advisory + $0 to $8 in fund ERs = $25 to $33/yr
  • Fidelity Go: $0 advisory + $0 fund ERs = $0/yr
  • Schwab Intelligent Portfolios: $0 advisory fee, but 6 to 30% of your portfolio sits in mandatory cash. At 10% cash, that’s $1,000 earning roughly 4% in Schwab’s sweep account instead of roughly 7% if invested. Opportunity cost: about $30/yr, plus around $12 in fund ERs.

At $25,000:

  • Betterment: $62.50 + $10 to $42 = $73 to $105/yr
  • Wealthfront: $62.50 + $0 to $20 = $63 to $83/yr
  • Fidelity Go: The 0.35% fee kicks in here. $87.50, with $0 in fund ERs = $87.50/yr
  • Schwab: $0 advisory, but 10% cash means $2,500 × roughly 3% drag = about $75/yr in opportunity cost, plus around $30 in fund ERs

At $50,000:

  • Betterment: $125 + $20 to $85 = $145 to $210/yr
  • Wealthfront: $125 + $0 to $40 = $125 to $165/yr
  • Fidelity Go: $175 + $0 = $175/yr
  • Schwab: Roughly $150 in cash drag + $60 in ERs = about $210/yr

At $100,000:

  • Betterment: $250 + $40 to $170 = $290 to $420/yr
  • Wealthfront: $250 + $0 to $80 = $250 to $330/yr
  • Fidelity Go: $350 + $0 = $350/yr
  • Schwab: Roughly $300 in cash drag + $120 in ERs = about $420/yr

Based on these assumptions, Wealthfront comes out cheapest in most tiers above $500. Fidelity Go wins below $25K since it’s literally free, then flips to one of the more expensive options. And Schwab, the platform marketed as no-fee, ends up costing growth-oriented investors more than anyone else at nearly every balance above $25K.

One mistake I see constantly: comparing advisory fees without adding fund expenses. Fidelity Go’s 0.35% looks steeper than Betterment’s 0.25%, but Fidelity uses its proprietary Flex funds with 0% expense ratios. At $50,000, Fidelity’s total cost ($175) can actually undercut Betterment ($145 to $210) depending on which Betterment portfolio you pick. The all-in number is the only number that matters.

Schwab’s “Free” Robo-Advisor Has an SEC Receipt

The marketing is effective enough that it ends the conversation for a lot of people. No advisory fee, no subscription, nothing. Free beats everything, right?

Except it’s not free. The SEC’s 2022 enforcement action laid it out plainly: Schwab’s algorithm allocated client cash to affiliated bank accounts, and Schwab kept the interest spread between what it earned lending that money out and what it paid clients. According to the SEC, Schwab’s own internal analyses showed the cash allocation reduced client returns “under most market conditions.” The company paid $187 million to settle, including $52 million in disgorgement and a $135 million penalty.

Schwab still requires a cash allocation of 6% to 30% depending on your risk profile. The more conservative your profile, the more cash sits uninvested. Think of it like a restaurant that doesn’t charge a cover but requires you to order three courses of bread.

At a moderate risk profile with roughly 10% in cash, here’s what happens on a $25,000 portfolio: $2,500 sits in cash earning around 4%. If that $2,500 were invested in the portfolio’s equity allocation instead, it would be expected to earn roughly 7% over time. That 3-point gap on $2,500 runs about $75 per year. Scale to $100,000 and you’re looking at $300/yr in invisible cost. That’s more than Betterment or Wealthfront charge in actual advisory fees.

Who should skip Schwab: Growth-oriented investors with a long time horizon. The cash drag compounds against you over decades, and the structural incentive hasn’t changed since the SEC action, even if the disclosures have improved.

Who should consider it anyway: Very conservative investors who want zero advisory fees on a $5,000-plus portfolio and actually want some of their allocation in cash. Schwab’s broader ecosystem, including 24/7 customer service and retirement planning tools, is genuinely good. Just go in knowing what you’re actually paying.

The Fidelity Go Fee Cliff (and How to Plan Around It)

For new investors moving their first $5,000 or $10,000 out of a savings account, Fidelity Go is hard to argue with. Zero advisory fee. Zero fund expense ratios (proprietary Fidelity Flex funds carry no ER). Automatic rebalancing. Real customer service. It’s a legitimately good product.

Then you hit $25,000.

Cross that threshold and the 0.35% annual fee kicks in, which is 10 basis points higher than Betterment or Wealthfront. On a $30,000 balance, that’s $105/yr versus $75 at either competitor. Not catastrophic, but it’s the opposite of the free deal you started with.

The bigger gap is tax-loss harvesting. Fidelity Go doesn’t offer it. Both NerdWallet and Morningstar confirm this. For taxable accounts, tax-loss harvesting (selling losing positions to offset gains, then reinvesting in similar assets) can add real after-tax value. Betterment claims 0.77% annually in TLH alpha. I’d discount that figure significantly for marketing optimism, but even cut in half, it represents meaningful money in a taxable account once you’re past $25K.

So the practical trigger: when your Fidelity Go balance approaches $22,000 to $23,000, start comparing what a transfer to Wealthfront or Betterment would look like. Not a reason to panic, just a reason to look before you’re paying 0.35% by default because you forgot to check.

Who should skip Fidelity Go: Anyone above $25K in a taxable account who cares about after-tax returns. You’ll pay more than Betterment or Wealthfront and miss the tax-loss harvesting.

Who it’s genuinely great for: Investors under $25K, especially in an IRA where tax-loss harvesting matters less anyway. Also a good pick if you’re already in the Fidelity ecosystem and want everything on one dashboard. Free is hard to argue with.

Betterment vs. Wealthfront: The Real Differences Between the Two 0.25% Platforms

Both charge 0.25%. Both do tax-loss harvesting. Both build a diversified ETF portfolio from a risk questionnaire. Picking between them requires getting into the details, and one of those details matters a lot more than the others.

The Betterment minimum trap: Wealthfront requires $500 to open an account. Betterment technically has no minimum, but if your balance is under roughly $24,000 and you’re not auto-depositing $250/month, you pay a flat $5/month. On a $10,000 balance, that’s $60/yr, which works out to an effective 0.60% fee rate. More than double the advertised rate. This is the fine print that makes Betterment a bad deal for smaller accounts, and most reviews bury it or skip it entirely.

Fund costs: Wealthfront’s underlying ETFs carry expense ratios between 0% and 0.08%. Betterment’s range from 0.04% to 0.17%. On a $50,000 portfolio, the difference could be $15 to $45 per year. Not life-changing, but it compounds.

Direct indexing: Wealthfront offers it above $100,000 (buying individual stocks instead of ETFs for more granular tax-loss harvesting). Betterment doesn’t offer a comparable feature at the standard tier. This is honestly where I’d push back on anyone automatically defaulting to Betterment at high balances.

Human advisors: Betterment Premium ($100K minimum, 0.65% fee) gets you unlimited access to certified financial planners. Wealthfront doesn’t have an equivalent. If you want a human in the loop eventually, Betterment is the cleaner path.

SRI options: Betterment offers a wider range of socially responsible investing portfolios. Wealthfront’s options are more limited here.

For most passive investors with $25K to $100K in a taxable account, Wealthfront is the better deal on pure cost. The fund expenses are lower, the TLH is comparable, and direct indexing is there when your balance grows into it. Betterment makes more sense if you want SRI portfolio choices, plan to use the Premium tier eventually, or just prefer the interface (not a trivial thing if you’re checking it every week).

When to Skip Robo-Advisors Entirely

If you’re reading this thinking “I could just buy a three-fund portfolio myself,” you’re not wrong. A self-directed account at Fidelity or Schwab with a total stock market index fund, an international fund, and a bond fund gets you broadly the same diversification for nothing but the fund expense ratio, often 0.03% to 0.05%. No advisory fee. No cash drag.

The tradeoff is behavioral. You have to rebalance yourself. You have to resist selling when the market drops 20% and your brother-in-law is texting you about moving everything to cash. And you get no tax-loss harvesting unless you do it manually, which is tedious enough that most people simply don’t.

If you want to go that route, our guide to the best brokerage accounts for beginners covers the platforms. And if you’re thinking about individual stocks alongside index funds, how to read a financial statement is the prerequisite most people skip.

But be honest with yourself. If you’ve been sitting in a HYSA for two years because picking investments feels overwhelming, a robo-advisor at 0.25% isn’t a failure. It’s $62.50 a year on a $25K balance to remove the friction that’s kept you earning 4% instead of something closer to 7%.

What to Actually Do With This Information

Start with Fidelity Go if you’re just beginning. Open an account, fund it with whatever you have beyond your emergency reserves, pay zero fees while you figure out how this all works. Put a calendar reminder at $22,000 to compare your options.

Check your actual all-in cost before assuming you’re getting a good deal. Pull up your latest statement, find the cash allocation percentage, look up your fund expense ratios, add everything together. If you’re at Schwab and your real cost (including cash drag) is running higher than what Wealthfront would charge, the transfer is probably worth an afternoon of paperwork.

Match the platform to the account type, not just to the fee. Tax-loss harvesting matters most in taxable brokerage accounts. If you’re in a Roth IRA, Fidelity Go’s lack of TLH is largely irrelevant, and its zero-ER funds make it competitive even above $25K. The platform that makes sense for your taxable account isn’t necessarily the right call for your IRA.

Where This Is Heading

The robo-advisor market is consolidating around a handful of winners. Schwab killed its premium tier in 2026. Vanguard Digital Advisor keeps lowering its minimums. The industry’s combined assets, somewhere between $634 billion and $754 billion according to Cerulli Associates data cited by Morningstar, still represent a small fraction of the $36.8 trillion US retail market. Fee compression will continue.

The thing I’d actually watch is whether direct indexing drops below the $100K threshold. Right now it’s a Wealthfront differentiator for higher-balance accounts. If that feature becomes available at $25K or $50K, it changes the after-tax math for taxable accounts significantly and makes the 0.25% fee easier to justify against the DIY alternative.

For now: run the dollar math at your actual balance, not the headline percentage. If you’ve been waiting to move past your HYSA, every year you delay is a year of earning 4% instead of something closer to 7%, and that gap compounds in the wrong direction.
