An account for those interested in higher interest. With High Interest Checking, the higher your balances, the higher the interest rate you’ll earn! Start with a higher interest rate with balances over $1,500 and get a premium rate when you make 20 or more Debit Card transactions per month*. Tiered rates go up from there! If your balance falls below $1,500, you’ll still earn a competitive rate. The monthly service charge is only $5 if your balance falls below $1,500.
