We are evaluating a project that costs $2,040,000, 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 89,700 units per year. Price per unit is $38.67, variable cost per unit is $23.80, and fixed costs are $851,000 per year. The tax rate is 22 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.
