Interest is our arithmetic on the APY shown, before tax, assuming the rate holds for a year (savings rates are variable). Complaint figures are CFPB checking and savings complaints from October 2025 to September 2026 for the whole company, per $1 billion of the bank's deposits in FDIC data.
Key differences
Wealthfront's 3.55% needs no deposit habit, and it adds 0.25% if you also have a funded Wealthfront investing account and $1,000 a month in direct deposits (or $2,500 in recurring deposits). Its advertised 4.45% includes a 0.65% new-client boost for three months on up to $150,000. SoFi's 3.30% needs direct deposit or $5,000 in deposits every 31 days, and new members can get up to 4.20% for six months through December 31, 2026. On $10,000 for a year at the base rates, that is about $355 against $330, if the rates held.
The structures differ. Wealthfront Cash is a brokerage account at Wealthfront Brokerage LLC that sweeps money to program banks; Wealthfront states coverage up to $8 million for individuals and $16 million joint. SoFi Bank, N.A. is itself an FDIC-insured bank and extends coverage to $3 million through partner banks. Both include a debit card: Wealthfront with 19,000+ fee-free ATMs and two out-of-network ATM fees refunded a month (up to $7.50 each), SoFi with 55,000+ Allpoint ATMs.
Wealthfront lists no account, transfer or overdraft fees, free domestic wires and ACH up to $250,000 a day. SoFi charges for outgoing wires and Instant Transfers; we could not confirm the amounts.

Compare these against every option in our high-yield savings comparison.
We summarize each bank's published terms, not user reviews. Facts come from our full reviews of both accounts, each checked against the provider's own pages on October 19, 2026 with every source listed; FDIC and CFPB figures come from the agencies' public data. We re-check about once a month. Some accounts are brokerage cash insured through partner banks. Some outbound links may be affiliate links. That never affects our comparisons. Nothing here is financial advice.
