You purchase a widget-making machine that can produce $5,000 worth of widgets each year for up to four years. However, there is a 12% chance that the machine will break entirely at the end of each year after the cash for that year has been produced. (This is roughly the process describing how incandescent light bulbs burn out, too.) What is the expected NPV of this widget machine? Assume a 8.9% discount factor, applicable beginning with the first $5,000
Probability of widget running succesfully each year end | = | 1-0.12=0.88 or 88% | |||||||
Calculation of probability of widget running each year | |||||||||
Year 1 start | 100% (because the failure ocurs at year end after generating first year cashflow.Hence first year probabilty will be 100% | ||||||||
Year 2 start | 100%*88%=88% | ||||||||
Year 3 start | 100%*88%*88%=77.44% | ||||||||
Year 4 start | 100%*88%*88%*88%=68.15% | ||||||||
