As with most ATM suppliers, in Moscow when you use an ATM that is not part of your own banking network, you will be charged a fee.  Most times the fee is a fixed fee per use of the ATM and is not dependent on the amount of money that you withdraw.  Obviously that means to save on fees, it is best to work out how much cash you are likely to need for a period of time - say a week, and then withdraw that amount of money from the ATM (so long as the daily limit allows you to).  Fees for the use of an ATM are generally around the US$5 mark.

Another useful tip is to consider using an ATM and a Money Changer to operate your own mini FX system.  When you withdraw money from an ATM (Russian Rubles for instance) your Bank will perform their own exchange rate conversion and commission charge, and they will debit your account the total amount.  If your account is in say USD, you will see an amount of USD equal to the Russian Rubles that you withdrew, then a separate entry (most times it shows separately) for the commission and fees the bank has charged, and then another entry for the fee charged by the foreign ATM provider.  If you work out the amount of USD the Bank deducted from your account for the Rubles and add to it the commission and fees that they charged, it will be most probably be about a rate of 22 to 23 Rubles per dollar (as at 1 January 2008).  If you check out the rates being offered by Money Changers, they will be buying USD at about 24.5 Rubles to the USD.  This means that a Money Changer would be offering you between 2 - 2.5 Rubles per USD more than the Bank.  If you withdrew US$500 worth of Rubles from a USD currency account, that would mean if you had withdrawn the actual US$500 and not the Ruble equal, and then taken the US$500 to a Money Changer, you would have received at least 1000 Rubles more than by withdrawing Rubles at the ATM from a USD currency bank account.  1000 Rubles is not enough to build an empire with, but it buy s good meal for 2 at a good cafe and let's face it, better in your pocket than the Banks!
