Our verdict

The 4.30% promo rate is among the higher rates we track, and the standard rate it falls back to, currently 4.00% APY, is still competitive. There are no fees, no balance rules and the minimum is $1. Our score uses the standard rate, not the 90 day promo, so the promo does not lift this account in our ranking. Learn how Raisin rate locks work, or compare it with American Express savings, or with BMW Bank, the other Raisin savings account we track.

The trade offs come from Raisin: everything runs through its platform, money moves only by transfer, and its app is weakly rated (2.9 on the App Store, 2.5 on Google Play). If you want to bank with Western Alliance directly instead, see our review of its High Yield Savings Premier, a separate account.

How much can you earn?

Deposit	First 90 days at 4.30%	One year at the standard rate

$50,000	$522	$2,000
