A private gym is looking at a new set of sports equipment with an installed cost of $490,000. This cost will be depreciated straight-line to zero over the projects five-year life, at the end of which the sports equipment can be scrapped for $71,000. The sports equipment will save the gym $148,000 per year in pretax operating costs, and the equipment requires an initial investment in net working capital of $29,500. If the tax rate is 22 percent and the discount rate is 10 percent, what is the NPV of this project?
