There are more than 400,000 ATMs in the United States, according to the American Bankers Association. The median cost of ATM fees in the U.S. is $2.33, according to Bankrateom's 2010 Checking Study, but that number can vary greatly. Remember, too, that you're likely to pay two fees when you use ATMs out of your network -- one fee to use the machine, and another fee to your own bank. The latter fee, called an "off-us" fee, add's another $1.41, meaning the median total fee for accessing your own cash on an ATM outside your own network is $3.74.
For money-savvy consumers, knowledge is power. Here's where you're likely to find the most expensive sources of cash and how you can avoid -- or at least minimize -- the costs.
