Your firm is contemplating the purchase of a new $518,000 computer-based order entry system. The system will be depreciated straight-line to zero over its 5-year life. It will be worth $50,400 at the end of that time. You will be able to reduce working capital by $70,000 (this is a one-time reduction). The tax rate is 24 percent and your required return on the project is 23 percent and your pretax cost savings are $164,550 per year. What is the NPV of this project?
