Comerica Maximize brings you a powerful package of cash management solutions to protect against fraud and manage your payments, receivables, loans and more, combined with interest checking.

The more you deposit, the more you earn on excess balances with tiered interest rates. What’s more, an Earnings Credit Allowance (ECA) allows you to offset some or all checking and cash management fees based on your balance.1
