(1) APY is Annual Percentage Yield. Percentages reflected are based on each specific Minimum investment amount ($1,000, $15,000 or $50,000). The Stated APY rates are accurate as of October 1, 2025. A penalty may be imposed for early withdrawal. Fees could reduce the earnings.
(2) The interest rate and annual percentage yield may change after account opening. The initial interest rate on your account will not change for the initial term of the account, unless you request and exercise the One Time “Bump Option”. For the 15 Month special, if the Rate on a GSB standard 18-mo term CD raises above the initial rate on your CD, or for the 33 Month special, if the Rate on a GSB standard 36-mo term CD raises above the initial rate on your CD, you may request the One Time Bump Option to have your yield adjusted to match the new yield for the remainder of the term. Limit one adjustment during term. This requires you to visit a Grinnell State Bank branch. Offer is subject to a $250,000 Deposit maximum for Non-Personal (entity) Depositors. Funds accepted for deposit are required to be “in state” or funds held within the State of Iowa.

What this means for you: When you open an account, we will ask for your name, address, date of birth, and other information that allows us to identify you. We may also ask to see your driver’s license or other identifying documents.
