In this study, through the application of input focused CCR Model under the assumption of fixed return to scale total activity value of decision making units was calculated. Three inputs and two output variables were selected in this direction. Total deposits / total assets (%), interest expenses / total assets (%), other operating expenses / total assets (%) were used as input variables. As output variables, total loans and receivables / total assets (%), interest incomes / total assets (%) were used. Analysis was conducted using the package program DEAP 2.1.According to the results of the analysis performed pertaining to input and output components created by adopting intermediation approach: While nine commercial banks are technically active in 2013 and 2014, this number is ten in 2015.According to the average efficiency ratings, 93.5% in 2013, 93.3% in 2014 and 96% in 2015 were reached. According to these results the activity levels of the commercial banks involved in the study have turned out to be high in the period covering 2013-2015 also progress has been observed in terms of their total factor productivity according to the years.
