Your firm is contemplating the purchase of a new $530,000 computer-based order entry system. The system will be depreciated straight-line to zero over its five-year life. It will be worth $50,000 at the end of that time. You will be able to reduce working capital by $65,000 (this is a one-time reduction). The tax rate is 34 percent and the required return on the project is 14 percent. If the pretax cost savings are $220,000 per year, what is the NPV of this project? If the pretax cost savings are $150,000 per year, what is the NPV of this project? At what level of pretax cost savings would you be indifferent between accepting the project and not accepting it?
