The Scientific and Technological Research Council of Turkey is the major academic research management and funding agency in Turkey. As a policy-maker, the council has undertaken very important responsibility in designing a science and technology policy of Turkey. By means of impact analysis, evaluating the ongoing research support programmes is important for designing more effective ones. However, impact of academic research are widely disseminated, journal articles being published and cited, number of academic staff involved in the supported projects, patents, and prototypes could be used as an evaluation instrument for impact analysis. In this study first time, we have figured out the social benefits (in 2008 TL fixed prices) of academic research projects, specifically physics academic research projects that were supported during 1998-2008 by T&Uuml / BiTAK. Return of funds of T&Uuml / BiTAK supported physics projects during 2005-2008 was calculated as 142%, when rate of return was taken 28%.
