Interest Earned on Aion High Yield Business Accounts

Last reviewed: January 1, 2026

Terms of Interest Accrual

These terms are a binding supplement to the Aion Banking Terms of Service (“Agreement”). Any capitalized terms not otherwise defined herein have the same meaning as in the Agreement.

The Annual Percentage Yield (“APY”) offered on the Aion High Yield Business Account (“HYBA”) is 2.50%.

The APY is subject to change at any time and fluctuates in response to changes in the Effective Federal Funds Rate (“EFFR”). Adjustments to the APY will be determined at the sole discretion of Aion Financial Technologies, Inc. (“Aion”) and may occur without prior notice. For the most up-to-date information on Aion’s APY rates, please refer to this Agreement.

Transactions must post and settle to your Aion HYBA during a given month to qualify toward that month’s accrued interest. Transactions that are initiated during a given calendar month but which post and settle after that calendar month concludes will count towards your accrued interest for the following month. Aion reserves the right to reverse a given calendar month’s interest payment if we determine in our sole discretion that, including but not limited to, a transaction reversal after the end of that calendar month.

Not earning interest in a given month will not impact your ability to potentially earn interest in a subsequent month. The payment of interest in any given month does not create any obligation on our part to pay interest on any subsequent month.

Interest Calculation

Interest is calculated as simple interest daily and credited monthly, using the total Available Balance for your HYBA on any given day (“Total Balance”). Interest is computed on a calendar year basis. We pay interest on or before the 10th of each subsequent calendar month and we pay interest only in whole cents. Therefore, at the end of each monthly interest payment period, any fractional amount of interest less than half of one cent will be rounded down and any fractional amount of interest equal to half of one cent or more will be rounded up to the next whole cent. If you close your Account before interest has been credited to your Aion Account on the regular interest payment date for your Aion Account, no interest for the final interest payment period will be paid for that period. If your Aion Account is suspended or frozen, your Aion Account will not accrue interest during the time your Aion Account is suspended or frozen.

If eligible to earn interest, interest begins to accrue on the Total Balance. We use the daily balance method for calculating interest which applies a daily periodic rate to the Total Balance each day a balance is maintained based on that day’s ending Total Balance.

Interest will only be paid when the computed interest is at least $0.01. In such cases, Aion reserves the right to adjust or withhold interest payouts as outlined in this Agreement.

If you open an HYBA during a given month, you will earn the applicable APY for the portion of the month that you have an active HYBA. We reserve the right not to pay interest on any deposited item that is returned to us unpaid. Any interest accrued and payable for an HYBA will be paid to your HYBA.

Subject to Change

The interest payable on HYBAs, the qualifying conditions to receive interest, and the methods used to calculate interest are subject to change from time to time. Adjustments will be determined at the sole discretion of Aion Financial Technologies, Inc. and may occur without prior notice. For the most up-to-date information on Aion’s Terms and APY rates, please refer to this Agreement.
