The sample size was determined by using the formula of Yemane (1976) and a sample of 172 respondents was selected from 2 sub cities of Addis Ababa city administration using simple random sampling technique. A multiple linear regression model was used to determine the relative importance of each independent variable to determine SME’s capital structure. This study used econometric model of multiple linear regressions where leverage was regressed against Tangibility, Growth, Age, Profitability, GDP growth rate, Inflation and Interest rate. The data collected was presented using tables and analyzed using percentages, means, and standard deviation in line with the objectives of the study. The data was cleaned, coded, and entered in to STATA 13 for analysis. The findings of this research show that. Interest rate, age, profitability, growth opportunity and tangibility variables were found to be significant factors that affect capital structure decision measured by leverage of SMEs.enCapital Structure, Leverage, GDP growth, SMEs growth, Interest rate, InflationThesis
