The problem Research is how the influence of the cost of production materials, marketing costs and salary costs on profitability, how the influence of the costs of production materials on profitability (ROA), how the influence of marketing costs on profitability, how the influence of salary costs on profitability (ROA). This Research purpose to determine the correlated of simultaneous costs of production materials, marketing costs and salary costs on profitability (ROA), partial correlated of production material costs, marketing costs and salary costs on profitability (ROA) Analysis of the data used in this research is multiple regression analysis, the coefficient of determination (R2) is 0.540 meaning that 54.0% of the variation in profitability can be explained by the variable costs of production materials, marketing costs and salary costs, while 46.0% from other factors not examined in this study. The F test results obtained the calculated F value of 12.522 is greater than the F table of 2.90 or a significance of 0,000 <α (0.05), the hypothesis states that the variable costs of production materials, marketing costs and salary costs correlated on profitability. Based on the t test that the variable costs of production materials and salary costs affect profitability while the variable marketing costs have no correlated on profitability
