We are evaluating a project that costs $723,000, has a life of fifteen years, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 86,000 units per year. Price per unit is $37, variable cost per unit is $26, and fixed costs are $734,568 per year. The tax rate is 22 percent, and we require a return of 17 percent on this project. The projections given for price, quantity, variable costs, and fixed costs are all accurate to within +/18 percent. a. Calculate the best-case NPV. Best case b. Calculate the worst-case NPV
