Scenario analysis – consider several scenarios (usually best scenario, base case, worst scenario; several variables may have different values in different scenarios), calculate NPV for each scenario.

A proposed investment has a cost of $5000. It will have a life of 3 years. The cost will be depreciated straight-line to a book salvage value of $2000, and will be worth $2500 at the end of the project’s economic life. Year-end sales will be $3200 per year and Year-end costs will be $200 per year. It requires an initial investment in net working capital of $500. The NWC will be recovered at the end of the project. The appropriate discount rate is 10%, and the corporate tax rate is 30%.
