We are evaluating a project that costs $824,000, has a life of twelve years, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 85,000 units per year. Price per unit is $39, variable cost per unit is $24, and fixed costs are $835,536 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 +/- 11 percent.
