Where Each Wins

Rate

Wealthfront

Wealthfront pays 3.30% base against Betterment's 3.25%, and Wealthfront's boosts stack higher: a 0.65% new-client boost plus a permanent 0.25% bump with direct deposit and a funded investing account, reaching up to 4.20% versus Betterment's promotional 4.00%.

Withdrawal speed

Wealthfront

Wealthfront offers free instant withdrawals to eligible linked accounts 24/7, including weekends. Betterment withdrawals run at standard ACH speed.

FDIC coverage

Wealthfront

Wealthfront sweeps across up to 32 program banks for up to $8 million in coverage, $16 million joint. Betterment's sweep reaches $4 million, $8 million joint. Both are excellent; one is double.

Checking features

Wealthfront

The Wealthfront Cash Account includes a debit card, account and routing numbers, bill pay, and early direct deposit in the same account. Betterment keeps those features in a separate Checking account through nbkc bank, with Cash Reserve itself offering no ATM access.

Boost offers

Betterment

Betterment runs more frequent promotional boosts for existing clients, including recurring-deposit and tenure-based offers on balances up to $1 million. Wealthfront's permanent direct-deposit bump is steadier but smaller.

The Verdict

Wealthfront wins this matchup outright. Higher base rate, bigger boosts, double the FDIC coverage, instant 24/7 withdrawals, and checking features built into the same account. Betterment Cash Reserve is a competent product with genuinely good goal buckets, and it is the right choice for exactly one group: people whose investments already live at Betterment and who want one login. Everyone shopping for the cash account itself should open Wealthfront.
