The performance valuation of the economic enterprise inorder to confidence of limited resources’ optimum allocation is important affaire and as long as it isn’t use of appropriate indicator for performance measurement and stock value of the firm its value not toward reale value and capital doesn’t allocate truly. This subject is more sensitivity in inflation condition. The goal of this research is, study of inflation distortion to economic value added (EVA) that is an indicator of the firm’s valuation and present adjusted models, compare unadjusted EVA to adjusted EVA and their components and examine inflation’s effect and financial characteristic on inflation net distortion. The results of our study that is estimated with use of paires test and panel data regression model show unadjusted EVA and its component has significant difference in compare to adjusted EVA and its component, and there is no reason to assume that upwards and downwards distortions are offsetting. Also level of the distortions will depend greatly on degree of leverage (Net Debt Ratio) and amount of real assets(Fix Asset Ratio) and inflation rate.
