There are no tuition fees but a semester contribution of approx. 160 EUR per semester which also covers the usage of public transport in Weimar, Erfurt, Jena and local trains in nearly all of Thuringia.
For the exchange semesters (3rd and 4th semester) students are required to pay a handling fee of a total of 2,000 EUR and a reduced semester fee of approximately 65 EUR.
Besides these programme-specific handling fees you have to cover the general study fees and living expenses, possible costs for excursions and study trips as well as expenses you need to spend related to visa procedures.
Further information on the semester contribution are available here.
As usual in any studies, additionally, some modules like the study project may require students to cover costs for excursions or a study trip (travel and overnight stay) during the semesters.
