X co. is considering a project which would cost $50,000 now and yield $9000 per annum every year in perpetuity, starting a year from now. The cost of capital is 15%.Calculate the NPV of the project. Answer: Year Cash flow Discount factor Present Value $ 15% $ 0 (50,000) 1.0 (50,000) 1-infinity 9,000 1/0.15 60,0000 so, NPV is 10000.
This math is not a problem. I solved it another way. But, I need to why discount factor is (1/.15) at 1-infinity. Another thing I wanna know why discount rate 15% is called ” The cost of capital”. what does it mean?
