In this case study, financial data of 89 listed companies in Tehran Stock Exchange from 2010 - 2015 are analyzed and the relationship between capital structure with annual inflation rate and return on assets rate are studied. The results show that there is a meaningful negative relationship between the rate of return on assets and capital structure (ratio of short term debt to total assets, ratio of long term debt to total assets, ratio of total debt to total assets as independent variables).
