Best Robo-Advisors: Compare Costs, Cash, and Investment Help

This is an editorial shortlist based on documented services and costs, not a ranking of investment returns or a claim that we opened and tested every account. Start with a suitable account and portfolio, then compare the actual price you will pay.

Our shortlist by the decision you need to make

These are conditional picks. A service can be excellent for one balance and poor value for another, especially when fixed fees or thresholds apply.

Compare the fee at the same balance

The following hypothetical annual amounts assume constant balances, no promotions and the stated base arrangement. They exclude fund expenses, taxes, transfers and cash opportunity costs. A minimum makes a service unavailable even when a theoretical fee could be calculated.

Sources: Fidelity Go, Betterment, Wealthfront, Vanguard, Schwab and E*TRADE.

The Betterment percentage row assumes a small account meets the qualifying recurring-deposit condition. The Vanguard row deliberately shows gross pricing before credits; it is not the final advisory bill or an all-in cost. Fidelity Go's zero-expense-ratio Flex arrangement also differs from services whose ETF expenses are additional.

Fidelity Go: a strong small-account comparison

The absence of an advisory fee below $25,000 makes Fidelity Go attractive for someone starting a managed portfolio. It invests through a restricted Flex-fund lineup rather than a DIY fund menu.

At the threshold, the cost changes on the whole balance. A constant $24,999 account has no advisory charge, while $25,000 implies $87.50 annually. Coaching and eligible taxable harvesting also become relevant. Read our Fidelity Go review for the scope of that help, including its limits for retirement-income planning.

Choose it because you want its managed arrangement. Do not artificially stop appropriate saving merely to remain below a fee threshold; reassess the service and alternatives as the account grows.

Betterment: useful when the qualification fits naturally

Betterment's small-account economics depend on qualifying recurring deposits. At a constant $5,000, $60 of flat annual charges is very different from $12.50 under 0.25% pricing. If a qualifying contribution fits your budget anyway, the percentage arrangement may be sensible.

Its goal-oriented service and portfolio options may appeal to investors who want an organized plan. Premium provides a different advice arrangement at a different price. Technical account support should not be counted as equivalent to personalized planning.

Our Betterment review explains the pricing and transfer charge. Do not stretch a budget or move unsuitable assets solely to qualify for a fee tier.

Wealthfront: a clear percentage fee for digital management

Wealthfront's core portfolio charges 0.25% annually and starts at $500. That makes its advisory cost straightforward to model for an eligible small account without relying on a recurring-deposit qualification.

The service is particularly worth comparing for investors who value automated taxable-account management and accept a digital model. Its cash account, brokerage and specialized portfolios are separate products; the core rate and minimum do not automatically apply to all of them.

Read the Wealthfront review for tax-loss-harvesting limitations and transition questions. A harvested loss is not a dollar-for-dollar tax saving, and outside transactions can affect the result.

Vanguard Digital Advisor: compare net pricing correctly

Vanguard's index option starts with a gross advisory rate, then subtracts eligible retained fund revenue. Fund expenses still need to be included consistently. The correct comparison is the net advisory bill plus the actual investment expenses, without double counting the credit.

Enrollment can be a bigger issue than a small fee difference. Taxable accounts must meet the settlement-cash enrollment condition, potentially requiring sales of existing investments. Realizing a large taxable gain to save a modest annual fee deserves careful analysis.

Our Digital Advisor review provides a worked net-fee example and distinguishes the digital service from human-advice offerings.

Schwab: examine the portfolio's cash requirement

Schwab's no-advisory-fee structure is attractive, but the required cash allocation changes the comparison. Cash can provide stability and liquidity; it is not automatically wasted. It also may earn less than another suitable cash arrangement or change the portfolio's expected behavior.

For a hypothetical $25,000 account with 10% cash, a two-percentage-point yield difference would equal $50 a year. Those are illustrative inputs, not a quoted Schwab allocation or current rate gap. The full review explains the current cash-rate formula and tax-harvesting threshold.

E*TRADE Core Portfolios: a reasonable integration choice

Core Portfolios combines managed ETFs with a $500 starting point and 0.30% annual advisory rate. At $25,000, its advisory charge is only $12.50 more than a 0.25% service, before differences in fund expenses and other costs.

That gap may be reasonable if the account arrangement and service fit better. Current terms allow eligible taxable accounts to enroll in harvesting. If you know E*TRADE through employer stock, examine any sales and tax effects involved in moving those assets into management. See the Core Portfolios review.

What this shortlist does not assume

We do not rank providers by past model-portfolio returns, because different risk levels, cash allocations and measurement periods make simplistic comparisons misleading. We also do not assume every taxable investor benefits equally from harvesting or every customer needs ongoing human advice.

Subscription apps such as Acorns and Stash may offer habit-building or bundled services, but a flat charge can be expensive relative to a tiny balance. Compare the services you actually use, not a theoretical maximum bundle value.

A suitable target-date fund or simple DIY portfolio can also automate part of the work at lower explicit advisory cost. The best decision is the least complicated arrangement that meets your investment and service needs.
