There were two types of study costs in the universities between the two World Wars, one of them was the tution fee, and the other one was the additional fee. The tution fee had been part of the Hungarian educational system since the middle of the 19th century. Those university students whose parents were in low social status with low income could get tution fee discount or exemption because of their financial situation. But in the case of the different kind of additional fees, there were not any discount or excemption because these fees required for the maintenance of several university institution, like university canteen, patient care fund, or the provision fund of the University Council. The system of these additional fees was different in the Hungarian universities, some additional fees were the same, some not. There were difference in the amount of the additional fees too. In this study, we can see the changes of the additional fee system in Debrecen between the two World Wars. All of the additional fees will be presented, for example canteen fee, patient care fund, and the two type of maintenance surcharges which were made due to the influence of the great economic crisis.
