Therefore the accuracy of these predictions is important. Prior research has shown that cost forecast error is more than sales forecast error and has more effect on the earning forecast error and claimed that this error is due to ignoring the cost behavior. This research was investigated cost behavior forecast accuracy by studying 104 company from 2010-2015. Samples were separated to companies with symmetrical (equal) favorable and unfavorable sales forecast error and were compared. T test and Mann-Whitney tests were used for this purpose. The results showed that managers are not predicting the cost variability correctly; however, due to the symmetry of the earning forecast error in firms with equal sales forecasting error, it can be concluded that managers generally pay attention to cost behavior in their predictions. In other words, according to the proportion of sales forecast error and cost forecast error, the main reason for the earning forecast error is the error in predicting sales.
