Domain Money vs Merrill Guided Investing: Which Is Better in 2026?
Last updated July 2026
Short answer
Domain Money and Merrill Guided Investing are often compared, but they are built for different jobs. Domain Money is hands-off automated investing (robo-advisors) (none; human planning), best for a one-time flat-fee financial plan you implement yourself. Merrill Guided Investing is hands-off automated investing (robo-advisors) (automates a research-driven model portfolio), best for bank of america customers who want managed portfolios in the same app. Neither is universally better: pick Domain Money if you want a one-time flat-fee financial plan you implement yourself, Merrill Guided Investing if you want bank of america customers who want managed portfolios in the same app.
Both Domain Money and Merrill Guided Investing get grouped under “AI investing tools,” which is why people compare them, but they sit in different categories and answer to different needs. Below is a balanced, 2026 look at what each one does, whether it reads the brokerage you already use, how each is priced, and who each fits, so you can tell which job you are actually hiring a tool for. Where relevant, we note where Walnut sits in its own category: chat-driven management of your own broker. Walnut is not an investment adviser.

What is Domain Money?
Flat-fee financial plans built by CFP professionals, delivered as a project rather than an ongoing percentage relationship.
How it works: You pay a fixed price for a plan built with a CFP professional across a defined set of sessions, covering cash flow, goals, tax awareness and investment strategy. You then implement it at your own accounts. There is no assets-under-management fee because nothing is under management.
In practice, Domain Money’s AI none; human planning. It falls under hands-off automated investing (robo-advisors), which makes it best suited to a one-time flat-fee financial plan you implement yourself. On connecting an account it is “No (you keep and implement at your own accounts)”, and on execution it is “You place them”. It is priced as flat project fee for a plan (verify current).
One honest limitation: You implement the plan yourself, and there is no ongoing management, which is the point and is not what everyone wants.
What is Merrill Guided Investing?
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 falls under hands-off automated investing (robo-advisors), which makes it best suited to bank of america customers who want managed portfolios in the same app. On connecting an account it is “No (holds your money at Merrill)”, and on execution it is “Automated”. It is priced as percentage of assets, higher with an advisor (verify current).
One honest limitation: Priced above the cheapest automated services, and the portfolios lean on Merrill's own research and funds.
Domain Money vs Merrill Guided Investing: how they actually differ
The core difference is category. Domain Money focuses on a one-time flat-fee financial plan you implement yourself (none; human planning), and Merrill Guided Investing on bank of america customers who want managed portfolios in the same app (automates a research-driven model portfolio). On broker connection they differ too: Domain Money is “No (you keep and implement at your own accounts)” versus Merrill Guided Investing at “No (holds your money at Merrill)”. That shapes everything downstream: how personal the answers are, where trades settle, and how much control you keep over individual positions.
Domain Money vs Merrill Guided Investing: strengths and trade-offs
Every tool gives something up for what it does well. Here is the honest give-and-take on each, so you can weigh the specific strengths against the limitations that come with them rather than judging on the headline category alone.
Domain Money
Where it is strong
- A known price for a defined deliverable, which almost nothing in this industry offers
- No conflict about advice that shrinks a balance, because the fee is not tied to one
- You keep your accounts where they are
What to watch out for
- Implementation is yours, and a plan nobody executes is worth nothing
- A snapshot dates as circumstances change, so plan on repeating it every few years
Merrill Guided Investing
Where it is strong
- Integrated with Bank of America, including reward tiers that cut the fee
- Portfolios come from a large in-house research operation rather than a pure algorithm
- An advisor tier is available without moving firms
What to watch out for
- More expensive than the cheapest automated services unless rewards tiers apply
- Portfolios lean on Merrill's own funds and research, which is a narrower opinion than an open comparison
The key divider: does it read your real holdings?
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.
- Domain Money: manages a separate account it holds. Domain Money 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 Domain Money.
- 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.
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.
Domain Money vs Merrill Guided Investing: which should you choose?
There is no universal winner here; the right pick depends on the job you are hiring the tool for. Match the category to your intent rather than chasing a single “best.”
- Choose Domain Money if you want a one-time flat-fee financial plan you implement yourself. Its AI none; human planning, it is priced as flat project fee for a plan (verify current), and it fits hands-off automated investing (robo-advisors). It is built for someone who wants expert planning at a known price and is willing to place the trades and open the accounts themselves. Keep in mind that you implement the plan yourself, and there is no ongoing management, which is the point and is not what everyone wants.
- 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, it is priced as percentage of assets, higher with an advisor (verify current), and it fits hands-off automated investing (robo-advisors). 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 that priced above the cheapest automated services, and the portfolios lean on merrill's own research and funds.
Because both sit in the same category, the choice comes down to the finer details above rather than a fundamental difference in approach.
Domain Money vs Merrill Guided Investing: pricing and cost model
Cost is easy to misread when two tools charge in different shapes, so compare the model, not just the number. Domain Money is priced as flat project fee for a plan (verify current), while Merrill Guided Investing is priced as percentage of assets, higher with an advisor (verify current). 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.
Pricing and tiers change often. Confirm the current numbers on each provider’s own site before you decide; the framing above is point-in-time.

It connects the brokerage you already use through SnapTrade, lets you analyze and manage it by talking through Claude or ChatGPT, build thematic portfolios around a thesis, and place trades you approve. Read-only by default. See Walnut vs Domain Money and Walnut vs Merrill Guided Investing. Walnut is not an investment adviser.
