Dzengi.com charges exactly the same commissions as it is mentioned on the Fees and Charges page.
Nevertheless, please note that your own bank (or сorrespondent banks) may also charge additional fees for conducting transactions/transfers.
Since Dzengi.com uses an international payment service provider, transactions using bank cards (Visa, MasterCard) may be executed with an exchange to US dollars, which means the final sum might differ.
