Robo investing has become increasingly ubiquitous on practically every brokerage platform. Until Tuesday, Goldman Sachs restricted its robo-advisory service, Marcus, to people who had at least $10 million to invest.

Now anyone with at least $1,000 to invest in can access the same trading algorithms that have been used by some of Goldman Sachs’ wealthiest clients for a 0.35% annual advisory fee. But investing experts say there are more costs to consider before jumping on the robo-investing train.
