Marcus Invest Review (2026): Cost, Features, and Who It Suits
Last updated August 2026
Short answer
Goldman Sachs' automated investing service, built around model ETF portfolios and sold alongside Marcus savings products. It costs Percentage of assets (verify current), and on the question that decides most of the day-to-day experience, whether it works with the brokerage account you already have, the answer is: No (holds your money at Marcus). It suits an existing Marcus savings customer who wants automated investing in the same place and does not need anything unusual. Where it falls short: A conventional automated portfolio with no distinguishing feature beyond sitting next to Marcus savings. This review is published by Walnut, which competes with Marcus Invest, and is written from public information rather than collected user ratings.
What Marcus Invest is and how it works
A questionnaire sets a risk level, and Marcus invests in a diversified ETF portfolio built by Goldman Sachs, rebalancing automatically. The pitch is the pairing with Marcus high-yield savings so cash and investments sit in one place, rather than any distinctive portfolio approach.
In category terms it is hands-off automated investing (robo-advisors), and the AI component specifically automates a diversified ETF portfolio. That phrase is worth reading literally: across this market, "AI" covers everything from a rebalancing rule to a conversational assistant, and the products are not interchangeable just because they share the label.
What Marcus Invest does well
- Portfolios constructed by a large, well-resourced institutional investment team
- Sits alongside Marcus savings, which is useful if your cash is already there
- Low minimum to start
These are real advantages, and if they describe what you want, Marcus Invest is a reasonable choice regardless of what any competitor including us has to say about it.
Where Marcus Invest falls short
A conventional automated portfolio with no distinguishing feature beyond sitting next to Marcus savings.
- Little differentiates the portfolios from any other automated ETF service
- Check the current feature set carefully, since the product has been repositioned more than once
What Marcus Invest costs
Percentage of assets (verify current). Because it is not charged as a percentage of assets, the cost does not scale with your balance. That makes it proportionally cheaper as an account grows and relatively expensive on a small one, which is the opposite of how a robo-advisor fee behaves.
Fees change. The figure above is a guide rather than a quote, and the Marcus Invest pricing breakdown goes into what else you pay on top. Confirm current pricing on Marcus Invest's own site.
How Marcus Invest compares with the alternatives
| Product | Cost | Connects your broker? | Best for |
|---|---|---|---|
| Marcus Invest | Percentage of assets (verify current) | No (holds your money at Marcus) | Goldman-built portfolios alongside a Marcus savings account |
| Betterment | ~0.25%/yr | No (holds your money) | Set-and-forget automated investing |
| Wealthfront | ~0.25%/yr | No (holds your money) | Hands-off investing with planning built in |
| SoFi | Free automated investing | No (holds your money) | Beginners in one money app |
| Schwab Intelligent Portfolios | No advisory fee; ETF expenses apply (verify current) | No (holds your money at Schwab) | Hands-off investing with no advisory fee, if you accept the cash allocation |
Within hands-off automated investing (robo-advisors), the products differ less on capability than the marketing suggests. Cost and whether your money has to move are the two variables that actually change your experience.
Where Walnut fits, and where it does not
To be upfront, since this is our site: the one factual difference worth knowing is that Marcus Invest holds your money in its own account, while Walnut connects the brokerage you already have, read-only by default, and leaves your assets where they are. Walnut is free, with no paid plan and no fee on assets.
Where Walnut is the wrong choice: it will not manage money for you, it is not a registered investment adviser, it does no tax or estate planning, and it needs a brokerage account you already hold. If what you want is delegation rather than analysis, a robo-advisor or a human planner is the better answer and Marcus Invest may well be it. The full self-assessment is on the Walnut review.
The bottom line on Marcus Invest
Marcus Invest: Goldman Sachs' automated investing service, built around model ETF portfolios and sold alongside Marcus savings products, at percentage of assets (verify current). It fits an existing Marcus savings customer who wants automated investing in the same place and does not need anything unusual. The trade-off to accept: A conventional automated portfolio with no distinguishing feature beyond sitting next to Marcus savings. If that trade-off is one you are happy with, it is a sound choice.

Does Marcus Invest connect to my existing brokerage account?

Neither is better in the abstract, but moving money has tax consequences in a taxable account that connecting does not.
