Merrill Guided Investing vs Wealthfront: Which Is Better in 2026?

Prices checked October 2026. A price marked (Oct 2026) was read on the vendor's own pricing page; others are described without a number because we could not verify one.

Merrill's automated investing service, built on Bank of America research, with an optional tier that adds an advisor.

How it works: A questionnaire sets a goal and risk level, and Merrill invests in model portfolios built by its investment office, rebalancing automatically. A higher-priced tier adds access to a financial advisor. Preferred Rewards status at Bank of America can reduce the fee, which is the main reason existing customers choose it.

In practice, Merrill Guided Investing’s AI automates a research-driven model portfolio. It is a robo-advisor (hands-off automated investing), best suited to bank of America customers who want managed portfolios in the same app. On connecting an account: no (holds your money at Merrill). On execution: automated. Cost: 0.45%/yr, $1,000 minimum; 0.85%/yr with an advisor (Oct 2026).

One real limitation: Priced above the cheapest automated services, and the portfolios lean on Merrill's own research and funds.

Automated indexing with strong financial-planning tools. Best for hands-off investors who want planning bundled in.

How it works: You set your goals and risk level and fund an account, and Wealthfront allocates across a set of low-cost index ETFs, then rebalances and tax-loss harvests automatically. Its Path planning tool projects retirement and other goals against your linked accounts, and larger balances can unlock direct indexing that holds individual stocks to harvest losses more granularly.

In practice, Wealthfront’s AI automates indexing + financial planning. It is a robo-advisor (hands-off automated investing), best suited to hands-off investing with planning built in. On connecting an account: no (holds your money). On execution: automated. Cost: 0.25%/yr, $500 minimum (Oct 2026).

One real limitation: Limited control over individual positions.

Category comes first. Merrill Guided Investing focuses on bank of America customers who want managed portfolios in the same app (automates a research-driven model portfolio), and Wealthfront on hands-off investing with planning built in (automates indexing + financial planning). On broker connection they differ too: Merrill Guided Investing is “No (holds your money at Merrill)” versus Wealthfront at “No (holds your money)”. That shapes everything downstream: how personal the answers are, where trades settle, and how much control you keep over individual positions.

Every tool gives something up for what it does well. Below is the give-and-take on each, so you can weigh the specific strengths against the limitations that come with them, beyond the headline category.

For AI investing tools, the distinction that matters most is whether the tool works from your actual, connected positions or reasons from something else: a separate account it manages for you, or the tickers and numbers you feed it. It decides how personal the answers can be, and where your money physically lives.

• Merrill Guided Investing: manages a separate account it holds. Merrill Guided Investing does not read the brokerage you already use. It opens and holds a new account, then invests the money you move into it, so its view is limited to what sits inside Merrill Guided Investing.
• Wealthfront: manages a separate account it holds. Wealthfront does not read the brokerage you already use. It opens and holds a new account, then invests the money you move into it, so its view is limited to what sits inside Wealthfront.

On this specific question the two land on the same side, so the deciding factors between them are elsewhere: category, cost, and who each is built for. This holdings-aware angle is the one Walnut is built around: it connects the brokerage you already use and reasons from your live positions, read-only by default, with any trades left for you to approve.

Each one wins a different job, so the answer depends on which job you need done.

• Choose Merrill Guided Investing if you want bank of America customers who want managed portfolios in the same app. Its AI automates a research-driven model portfolio, and it costs 0.45%/yr, $1,000 minimum; 0.85%/yr with an advisor (Oct 2026). It is built for an existing Bank of America customer whose rewards tier makes the pricing competitive and who values everything in one app. Keep in mind: priced above the cheapest automated services, and the portfolios lean on Merrill's own research and funds.
• Choose Wealthfront if you want hands-off investing with planning built in. Its AI automates indexing + financial planning, and it costs 0.25%/yr, $500 minimum (Oct 2026). It is built for hands-off investors who want automated indexing with serious planning tools and a cash hub in one place. Keep in mind: limited control over individual positions.
• Choose Walnut if you want a keep, trim or exit read on the stocks you already own, and placing the trades you approve. It is an AI investing app that connects the broker you already use, and it costs free; Walnut Plus $9.99/mo on the web; no fee on assets.

Because both sit in the same category, the choice comes down to the finer details above. Their basic approach is the same.

Cost is easy to misread when two tools charge in different shapes, so compare the model, not just the number. Merrill Guided Investing: 0.45%/yr, $1,000 minimum; 0.85%/yr with an advisor (Oct 2026). Wealthfront: 0.25%/yr, $500 minimum (Oct 2026). A percentage-of-assets fee scales with your balance, a flat subscription does not, and a “free” tier usually earns elsewhere (on cash, order flow, or premium upgrades), so the cheapest headline is not always the cheapest outcome for your situation.

Walnut is an AI investing app, and it is the pick for a keep, trim or exit read on the stocks you already own, and placing the trades you approve (free; Walnut Plus $9.99/mo on the web; no fee on assets). It connects the brokerage you already use, read-only by default, gives each holding a keep, trim or exit read against the S&P 500, flags any position above a quarter of the portfolio, and places the trades you approve. You use it through its own assistant, or inside Claude or ChatGPT. See Walnut vs Merrill Guided Investing and Walnut vs Wealthfront.
