Best Robo-Advisors Compared: Fees, Minimums, Tax-Loss Harvesting (2026)

Updated June 21, 2026

Best Robo-Advisors for Your Money: Every Major Platform Compared on Fees, Minimums, and Tax-Loss Harvesting

Schwab Intelligent Portfolios advertises a $0 management fee. But it requires parking 6–29% of your portfolio in cash inside Schwab's bank subsidiary — and that cash drag is a cost, even if it doesn't show up on a fee schedule. With an illustrative 20% cash allocation and an assumed 3.5% equity-versus-cash spread, a $100,000 investor loses roughly $700 per year in foregone gains. That's nearly three times what Betterment charges in advisory fees on the same balance. The advertised fee is never the full picture.

• Best overall: Wealthfront — 0.25% fee, $500 minimum, daily tax-loss harvesting on all taxable accounts, and direct indexing at $100,000 makes it the most complete platform for taxable investing. - Best for small accounts: Fidelity Go — truly $0 total cost under $25,000 thanks to zero-expense-ratio Fidelity Flex funds, with just a $10 minimum to start. - Best for zero-fee investing: SoFi Automated Investing — $0 advisory fee, $1 minimum, no catch — though you give up tax-loss harvesting entirely. - Best for low-cost buy-and-hold: Vanguard Digital Advisor — the lowest percentage-based fee among traditional providers at up to 0.20% net (after advisory fee credit), with a $100 minimum and a 90-day free trial.

Comparison Table

Vanguard's gross advisory fee is 0.20%, reduced by an advisory fee credit that varies by portfolio. The net fee for most investors lands between 0.15% and 0.20%. Confirm your rate at vanguard.com.

Note on cash allocations: Every platform holds some cash for rebalancing and trade settlement, typically 1–2% of the portfolio. Schwab's allocation is uniquely large (6–29%) because it's the platform's primary revenue source instead of an advisory fee.

Best For Picks

Best overall: Wealthfront. Daily tax-loss harvesting on every taxable account starting at just $500 is unmatched. Add direct indexing — stock-level tax-loss harvesting — at $100,000, plus standalone S&P 500 Direct and Nasdaq-100 Direct options starting at $5,000 (wealthfront.com), and no other platform offers this much tax optimization at this price point.

Best budget pick: Fidelity Go. Zero advisory fee and zero fund expense ratios on accounts under $25,000, per Fidelity's published pricing. Your first $25,000 grows with literally no drag from fees. For a new investor saving $500 a month, that's roughly two years of completely free professional management.

Best for large taxable accounts: Betterment Premium. At $100,000+, Betterment's 0.40% Premium tier pairs automated tax-loss harvesting with access to certified financial planners (CFPs) — the only platform here offering human advisor access alongside robo-management. If Betterment delivers its planned direct indexing launch in 2026, it could match Wealthfront's tax optimization while adding the human touch.

Best for set-and-forget simplicity: Vanguard Digital Advisor. At up to 0.20% net annually with access to low-cost Vanguard funds, the all-in cost is among the lowest in the industry (vanguard.com). The 90-day free trial lets you test the interface before committing.

Betterment

Betterment has been around since 2010 — one of the earliest robo-advisors to hit the mainstream — and it's still the default recommendation for a reason. The standard tier charges 0.25% annually with no account minimum (betterment.com). Tax-loss harvesting is available on all taxable accounts. A Premium tier offers access to CFPs at 0.40% annually with a $100,000 minimum — though you should confirm exact Premium pricing directly at betterment.com/pricing as fee structures have shifted in 2026.

Betterment has announced plans to launch direct indexing and Unified Managed Accounts (UMAs) in 2026, per their Advisor Solutions Q4 2025 update. If delivered, this would close the gap with Wealthfront's tax optimization edge.

Pros: No account minimum, tax-loss harvesting included, premium tier with human advisors, clean interface, goal-based planning tools.

Cons: 0.25% adds up on large balances (a $500,000 portfolio pays $1,250/year), direct indexing not yet available, Premium tier is expensive for what amounts to occasional CFP access.

Who should skip it: If you have under $25,000 and don't need tax-loss harvesting, Fidelity Go costs you nothing.

Wealthfront

Wealthfront charges the same 0.25% as Betterment but wins on tax optimization. Daily tax-loss harvesting runs on all taxable accounts with just $500, per Wealthfront's support documentation. At $100,000, you unlock full US Direct Indexing — the platform buys individual stocks from a broad index and harvests losses at the security level. S&P 500 Direct and Nasdaq-100 Direct are available starting at $5,000.

Pros: Daily tax-loss harvesting at $500, direct indexing at $100K, low fund expense ratios, financial planning tools, $500 minimum.

Cons: No human advisor option, $500 minimum is higher than Betterment's $0, direct indexing requires $100K for full index.

Who should skip it: If your money is entirely in tax-advantaged accounts (Individual Retirement Accounts, 401(k) plans), tax-loss harvesting provides no benefit. You're paying 0.25% for portfolio management you could replicate with a single target-date fund.

Schwab Intelligent Portfolios

Schwab's headline: $0 advisory fee. The catch: a mandatory cash allocation of 6–29% of your portfolio sits in Schwab's bank subsidiary, where Schwab earns the spread Your actual cost depends on cash yields, market returns, and your specific allocation; the point is that $0 advisory fee doesn't mean $0 total cost.

Tax-loss harvesting requires a $50,000 minimum balance (schwab.com). Schwab discontinued its Intelligent Portfolios Premium hybrid tier in Q1 2026, according to Investment News reporting, joining JPMorgan, UBS, and U.S. Bank in retreating from hybrid robo-advisory models. No human advisor option remains at Schwab's robo level.

Pros: $0 advisory fee, strong brand trust, access to Schwab's broader ecosystem, no advisory fee on any balance size.

Cons: Cash drag is a hidden cost that can exceed competitors' explicit fees, $5,000 minimum, tax-loss harvesting only at $50K+, no human advisor option after Premium discontinuation.

Who should skip it: Anyone with a balance under $50,000. Without tax-loss harvesting and with the cash drag eating returns, you're paying more than you would at Betterment or Wealthfront — you just can't see the fee on a line item.

Vanguard Digital Advisor

Vanguard Digital Advisor charges up to 0.20% net advisory fee — Vanguard applies a credit against their gross advisory fee, so most investors pay between 0.15% and 0.20% depending on portfolio composition. The $100 minimum and 90-day free trial make it accessible. Portfolios are built from low-cost Vanguard funds, keeping the all-in cost well under 0.30%.

Pros: Lowest percentage-based fee, Vanguard fund access, $100 minimum, 90-day free trial, trusted brand.

Cons: Limited tax-loss harvesting compared to Wealthfront or Betterment, no direct indexing, less sophisticated planning tools, basic interface.

Who should skip it: Tax-conscious investors with large taxable accounts. Vanguard's tax optimization doesn't match Wealthfront's daily harvesting or direct indexing capabilities.

Fidelity Go

Fidelity Go is the best deal in robo-advising for small accounts. Accounts under $25,000 pay absolutely nothing — $0 advisory fee plus 0.00% expense ratio Fidelity Flex funds, per Fidelity's published pricing. Above $25,000, the fee jumps to 0.35% annually, and tax-loss harvesting becomes available on taxable accounts.

Think of it like a free gym membership that charges once you start using the sauna — you get the core service free, and pay only when you want premium features.

Pros: Truly $0 cost under $25K, zero-expense-ratio funds, $10 minimum, access to Fidelity's ecosystem.

Cons: 0.35% is above average once you cross $25K, tax-loss harvesting limited to $25K+ taxable accounts, less sophisticated tax optimization than Wealthfront.

Who should skip it: Investors with $50,000+ in taxable accounts. At that level, Wealthfront's daily tax-loss harvesting and direct indexing access deliver more value even at 0.25%.

SoFi Automated Investing

SoFi charges $0 with a $1 minimum (sofi.com). No asterisks, no cash drag tricks. The trade-off: SoFi does not offer tax-loss harvesting at all, per SoFi's own disclosures.

For SoFi's core audience — beginners investing their first few thousand dollars — the missing tax-loss harvesting matters less than you'd think. Tax-loss harvesting on a $3,000 portfolio might save $10–$30 per year, depending on market volatility and your tax bracket. At that scale, paying 0.25% elsewhere to access harvesting costs more than the harvesting saves. SoFi's real pitch is removing every barrier to getting started.

Pros: $0 fee, $1 minimum, SoFi ecosystem perks (rate discounts on loans), simple interface.

Cons: No tax-loss harvesting whatsoever, limited customization, smaller fund selection.

Who should skip it: Anyone with a taxable brokerage account above $10,000. As balances grow, the absent tax-loss harvesting becomes a real cost that Wealthfront or Betterment would capture for you at 0.25%.

Pricing Breakdown: The True All-In Cost

The advertised management fee is only part of the cost. Here's what a $100,000 portfolio actually costs annually at each platform:

| Platform | Advisory Fee | Est. Fund Expenses | Est. Cash Drag | Est5% equity-versus-cash return spread. Actual drag depends on market conditions and your assigned cash percentage. All other platforms hold 1–2% cash for trade settlement, reflected in the small cash drag estimates above.

Over 20 years on a $100,000 initial investment growing at 7% annually, the difference between a 0.20% all-in cost (Vanguard) and a 0.60% all-in cost (Schwab with moderate cash drag) compounds to roughly $35,000. Fees are the one variable you fully control — and compounding works against you just as powerfully on costs as it works for you on returns.

Verdict

Wealthfront wins for most investors with taxable accounts. Daily tax-loss harvesting at $500, direct indexing at $100,000, and a 0.25% fee with minimal cash drag make it the most complete tax-optimized robo-advisor available.

Fidelity Go wins for beginners. If you're investing your first $25,000 and don't have a taxable brokerage account yet, zero total cost is unbeatable.

Vanguard Digital Advisor wins for cost-conscious buy-and-hold investors who want the lowest possible all-in fee and don't need advanced tax optimization.

The one scenario where Schwab makes sense: you have $100,000+, plan to hold long-term, and genuinely value the $0 advisory fee line item more than the hidden cash drag. For most people, that trade-off doesn't pencil out.

Is a robo-advisor worth it?

For taxable accounts over $25,000, yes — tax-loss harvesting alone can generate value exceeding the advisory fee, especially in higher tax brackets. For tax-advantaged accounts like IRAs, a single target-date fund often achieves the same result at lower cost.

Which robo-advisor has the best tax-loss harvesting?

Wealthfront, by a significant margin. Daily tax-loss harvesting on all taxable accounts starting at $500, plus direct indexing at $100,000. No other platform matches this combination of low minimums and harvesting sophistication.

Are "free" robo-advisors really free?

SoFi's $0 fee is genuinely free — you pay only the underlying fund expense ratios (typically 0.03–0.07%). Schwab's $0 fee comes with mandatory cash allocations that can cost more than a competitor's explicit advisory fee. Always calculate the all-in cost, not just the management fee.

Should you use a robo-advisor or just buy index funds yourself?

If you're comfortable selecting and rebalancing a three-fund portfolio (total U.S. stock, international stock, bonds), you can replicate most robo-advisor portfolios at lower cost. The value of a robo-advisor is automated rebalancing, tax-loss harvesting, and behavioral guardrails — which matter most in taxable accounts with balances above $25,000.

How much do you need to start with a robo-advisor?

As little as $1 at SoFi or $10 at Fidelity Go. But tax-loss harvesting — the primary value-add for taxable accounts — doesn't kick in until $500 at Wealthfront, $25,000 at Fidelity Go, or $50,000 at Schwab.
