We are evaluating a project that costs $1,980,000, has a life of 7 years, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 89,100 units per year. Price per unit is $38.55, variable cost per unit is $23.70, and fixed costs are $845,000 per year. The tax rate is 25 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. (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answers to 2 decimal places, e.g. 32.16.) OCF NPV Best-case Worst-case
