And a quick stop at the ATM could cost a lot more than you're expecting. A new survey being released by Bank Rate shows the average fee for using an out of network ATM has risen 21 percent in the past five years. Now it's up to a record $4.52 per transaction. The spike is due in part to banks being pressured to lower other fees.
