Deposit rates and terms

***APY=Annual Percentage Yield. Rates Subject To Change Without Notice. Rates as of 1.1.2025. The minimum balance requirement is $100 for members age 18 and under to earn the stated APY.

Bonus rate of 0.25% may be applied to any certificate except 15-month opened with new funds of $2,500 or more not currently on deposit at Arsenal Credit Union.

All certificates have the option of paying quarterly or monthly interest that would be transferred to another Arsenal Credit Union account. Interest checks may be paid monthly for all certificates with a $10,000 minimum balance. Selecting any of these interest options will affect the annual percentage yields quoted on this rate sheet – the annual percentage yields are calculated based on quarterly compounding of the interest. Fees may reduce earnings on the account. A penalty rate may be imposed for early withdrawal.

Premier Checking account is subject to a Tiered Variable Rate. Balances up to $15,000 receive APY of 4.25%; balances over $15,000 earn a rate of .08% on the portion over $15,000 resulting in 4.25% – 0.61% APY depending on balance (APY range calculated assuming a balance of $115,000). If qualifications for higher yield are not met, all balances earn .08% APY. In order to avoid a $5.00 monthly fee, you must maintain an average daily balance (ADB) of $2,500.00 in your account each month. No transaction limitations apply to this account. In order to earn the disclosed APY and be reimbursed for domestic ATM fees incurred (during each dividend period you will be reimbursed up to a total of $25.00, if qualifications are met), during each dividend period you must: (a) make 15 or more debit card transactions using your Visa Check Card (that post and clear your account as evidenced by your monthly statement); (b) consent to receive your periodic statements electronically (eStatements); and (c) make at least one direct deposit transaction into the Premier Checking account each dividend period.
