A new project will cost $100,000. It will increase sales by 80,000 units but will also increase annual fixed costs by $15,000. Selling price per unit is $6.20 and variable cost per unit is $5.20. The project will also require initial investment of $18,000 in net working capital. The project will last for three years, and depreciation will be straight-line to zero. Interest expense will be $5,000. Given that the required rate of return on this project is 18%, and the marginal corporate tax rate is 40%, what is the net present value of this project? Ignore the half-year rule.
