Wealthfront Cash Account review

Wealthfront Cash Account ranks first because it combines a rate near the top of this list with the widest deposit insurance and the fastest access. The base APY was 3.55% as of October 1, 2026, and the account charges zero account fees. Wealthfront says it is not a bank: it places cash with program banks, which is how it reaches up to $8M in FDIC insurance eligibility, well beyond the $250,000 a single bank covers per ownership category. New clients get a 0.65% APY boost for 3 months on up to $150,000, and clients who invest and keep depositing monthly get an ongoing 0.25% increase, which together explain the headline 4.45% figure. Free 24/7 instant withdrawals to eligible external accounts and reimbursement of 2 out-of-network ATM fees per month make it work like checking too. The trade-offs are that the top rate is temporary, the boosts stop at $150,000, and savers who want a traditional bank relationship may prefer Marcus or Ally.
