Sam wants to start a lighted grille insert manufacturing company company. He just spent $20000 on a market survey and decided to proceed. The equipment needed to begin production will cost $250,000. The projected sales of the product is 5,000 units in the first year, with expected growth rate of 10% each year for the next 10 years. Production of these units will require additional $10,000 in net working capital at the start, and continue at the same level. The product is priced at $50 each. Total fixed costs are $75,000 per year, variable production costs are $20 per unit. The equipment will be depreciated using the straight-line method over the 10-year life and is expected to have a salvage value of $50000 at the end of life. The effective tax rate is 30 percent, and the required rate of return (discount rate or hurdle rate) is 15 percent. What is the NPV, IRR, and the payback period of this venture?
