The Campbell Company is considering adding a robotic paint sprayer to its production line. The sprayers base price is $920,000, and it would cost another $20,000 to install it. The machine falls into the MACRS 3-year class, and it would be sold after 3 years for $500,000. The MACRS rates for the first three years are 0.3333, 0.4445, and 0.1481. The machine would require an increase in net working capital (inventory) of $15,500. The sprayer would not change revenues, but it is expected to save the firm $304,000 per year in before-tax operating costs, mainly labor. Campbells marginal tax rate is 25%. Show me how to calculate the PV's for each cashflow in excel with all inputs in order to get the NPV for the last question on this problem which asks: If the projects cost of capital is 12%, what is the NPV? Show me all the work for solving that last problem.
