It's getting more important to consider the size and scope of your bank's network of A.T.M.'s if you use them frequently.
An annual analysis of checking accounts from Bankrate.com finds that the average A.T.M. surcharge - the fee charged by the machine's operator to a noncustomer - rose 4 percent to a new record of $2.50.
This is the eighth consecutive year that the average surcharge has increased. And, for the first time, all of the banks surveyed by Bankrate.com for the report charge noncustomers to use their A.T.M.'s.
The increases are part of an overall attempt by banks to replace fee revenue lost because of new caps on the amount they can charge retailers for debit-card transactions.
The surcharge gets even more expensive when your own bank gets into the act, charging you - its customer - for using a competitor's machine. This fee rose 11 percent, to $1.57.
For a customer encountering both fees, the average total of $4.07 is also a new record. It is up almost 7 percent from last year.
What steps do you take to avoid A.T.M. surcharges? And what's the biggest one you've ever paid?
