Consider an investment project. It needs today a $0.4 million investment in a plant that will generate revenues of $1 million and operating costs of $0.6 million each year for the next 4 years. You expect to depreciate the investment to zero over its horizon (4 years) using straight-line depreciation. Your current tax rate is 30% and your opportunity cost of capital is 12%. What is the annual cash flow before taxes for the next 4 years? What is your annual tax payment for the next 4 years? What is the NPV of the project?
