The Associated Bank Advantage Savings Account is an interest-bearing account that offers free online banking and free ATM deposits. A minimum $1,000 opening deposit is required. To avoid fees, you must maintain an average monthly balance of $2,500 (or $1,000 if you have an Associated Bank checking account too). Interest is credited and compounded monthly. You get two free non-Associated ATM withdrawals each month (there's a $1.50 fee for additional withdrawals).
