Summary: The paper deals with the problem of financial literacy of students graduated on secondary schools. We tested sample of 25 students at university level in the 1st year of study to be a teacher of mathematics. Because of the new school reform in year 2008 the basic financial mathematics is obligatory part of the mathematics education at secondary school. In our research we tested students - future mathematics teachers - without any additional financial education (to the previous mathematics curriculum on secondary school), if they have sufficient knowledge from financial mathematics because of need in their future praxes. The results imply that their knowledge is not sufficient and therefore there is need to prepare new curricula for preparation of future mathematics teachers.
