*APY = Annual Percentage Yield
Special Offer
Lock in 3.91% annual percentage yield for 6 months.
What’s better than a warm, midwestern welcome? Locking in today’s leading rate for the next 6 months.
*Annual Percentage Yield (APY) may change at any time. This is a variable-rate, tiered savings account. The APY you earn depends on your account balance and applies to the entire balance within the applicable tier: 0.05% APY for balances of $100–$2,499.99, 3.01% APY for balances of $2,500–$9,999.99, and 3.91% APY for balances of $10,000 or more. Accounts that reach $10,000 at opening or within the first 30 calendar days may qualify to lock in the headline APY for a six-month period; accounts reaching $10,000 after the initial 30 days are not eligible for the rate lock. After any rate-lock period ends, or if a rate lock does not apply, the account will earn the then-current APY for the applicable balance tier. Interest is calculated using the daily balance method, compounded monthly, and credited monthly. Minimum deposit to earn dividends is $100. Fees and transaction limits may apply and could reduce earnings. See the Account Agreement for complete terms and conditions.
