We are evaluating a project that costs $814,000, has a life of ten years, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 110,000 units per year. Price per unit is $35, variable cost per unit is $27, and fixed costs are $825,396 per year. The tax rate is 21 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 +/16 percent. a. Calculate the best-case NPV. b. Calculate the worst-case NPV
