SoFi Invest Minimum Investment (2026): What It Takes to Open an Account

Guides › Financial Advisor Fees

Updated September 18, 2026. Quick answer: SoFi Invest does not impose a minimum account size for SoFi Wealth Robo Investing. Its own brochure states there is no minimum account size, though cash is only invested once it reaches a $50 threshold.

The minimum, in the firm’s own words

“There is no minimum account size, but clients should be aware that there is a $50 threshold for investment of cash.”

SoFi Invest’s own fee schedule at other balances

Account balanceAnnual fee
$250,000$625
$500,000$1,250
$1,000,000$2,500
$2,000,000$5,000

What else to know

SoFi’s brochure states there is no minimum account size to open a Robo Investing account. The only dollar figure disclosed, $50, is a threshold for investing cash within an already-open account, not an opening minimum.

What a larger account would cost

The minimum is only the entry point. On a $500,000 account, SoFi Invest’s own published fee schedule runs $1,250 a year; see the full dollar breakdown from SoFi Invest’s own fee disclosure across several account sizes.

Already a client and thinking about the minimum a different way, like whether you could get a better deal elsewhere? Read the general mechanics of switching financial advisors, or use a dated termination letter once you decide.

Methodology. This page was built September 18, 2026, quoting directly from SoFi Invest’s own current Form ADV Part 2A / wrap-fee brochure, with the source linked above. The annual-fee-at-the-minimum figure applies that same brochure’s own published fee schedule to the disclosed minimum dollar amount; any distinction we could not independently confirm this session is named as an honest gap rather than presented as verified. Nothing here is personalized financial, tax, legal, or investment advice, and it is not a substitute for reading the firm’s own Form ADV Part 2A.
