Explanation of Assumptions This is only a speculation of values for the 24-month projection that has been grounded on quantitative assumptions. For example, I have assumed the 24-month projection on sales will grow by 1,953 cost of goods sold by 10.76%, and other incomes by 0. Additionally, the interest expense for the two-year projection is expected to increase by 13.9. However, in the case of income tax, the income tax expense has been computed as a constant of 28.52% of income before income tax. Based on the 24-month projection, the new product is expected to increase the company's profitability by generating more revenue.
