*APY = Annual Percentage Yield. The interest rates and APYs are effective as of May 8, 2025. 

1. Limited time offer only available when opening in Byline Bank branches or online. $5,000 minimum deposit to open. $5,000 minimum to earn Annual Percentage Yield (APY). New funds only, defined as new to Byline. Certificate of Deposit (CD) offering 4.05% APY has a term of 6 months, and applies the simple interest method, with interest paid at maturity. We reserve the right to cancel or change the promotion at any time. Promotional CDs may renew into a different term. We send you a maturity notice prior to renewal. Please read it carefully.

Rates and Interest

Rates and annual percentage yields (APYs) are set at the bank’s discretion and are subject to change without notice. The APY assumes that interest remains on deposit until maturity. An early withdrawal will reduce earnings. A penalty may be imposed for early withdrawal. The 6-month promo CD must be opened with new funds, defined as new to Byline.
Interest may be paid by transfer to another internal account, at your option. You will forfeit any accrued interest that has not yet been credited to your account if the account is closed prematurely. We use the daily balance method to calculate the interest on this account. This method applies a daily periodic rate to the principal in the account each day. Interest begins to accrue on the business day you deposit any non-cash item (for example, checks).

Withdrawals

You may not withdraw any principal from this CD before maturity without our consent, which may be withheld; if we permit such a withdrawal, you may have to pay a penalty as follows: A) Where the original maturity of the account is one year or less, the penalty will be forfeiture of 90 days interest on the amount withdrawn, at the nominal (simple interest) rate in effect during the term. B) Where the original maturity of the account is more than one year, the penalty will be forfeiture of 180 days interest on the amount withdrawn at the nominal (simple interest) rate in effect during the term. C) If the withdrawal is within 6 days after the date of first deposit, a minimum of 7 days of interest will be charged as a penalty. You must withdraw funds within the grace period to avoid being charged a penalty. Fees could reduce the earnings on the account.

Renewal

Unless you notify us in writing before the maturity date, or within the grace period, CDs will automatically renew on the maturity date. The grace period is ten (10) calendar days for CDs with a term greater than 31 days and is three (3) calendar days for CDs with a term 31 days or less. We can prevent automatic renewal if we notify you in writing on or before the maturity date that we do not intend to renew the account. Promotional CDs may renew into a different term. If you close your CD during the grace period, no accrued interest will be paid after the maturity date. We send you a Maturity Notice prior to renewal, please read It carefully. We may change the type, term or other feature of your CD by giving you notice. If we make a change, we tell you about the change in the Renewal Notice. See Personal Deposit Account Agreement and Disclosures for additional terms and conditions.
