We are evaluating a project that costs $867,000, has a life of twelve years, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 88,000 units per year. Price per unit is $39, variable cost per unit is $27, and fixed costs are $880,872 per year. The tax rate is 24 percent, and we require a return of 15 percent on this project. The projections given for price, quantity, variable costs, and fixed costs are all accurate to within +/- 12 percent. a. Calculate the best-case NPV. Best case b. Calculate the worst-case NPV.
