We are evaluating a project that costs $2,070,000, has a 7-year life, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 93,400 units per year. Price per unit is $38.73, variable cost per unit is $23.85, and fixed costs are $854,000 per year. The tax rate is 23 percent and we require a return of 12 percent on this project. Suppose the projections given for price, quantity, variable costs, and fixed costs are all accurate to within 10 percent. Calculate the best-case and worst-case NPV figures.
