NRE=$5,000

unitcost=$30

timetomarket=12months(88monthsofmarketwindowremaining)

Revenue=1/2base*heigth

=1/2*100months*$100,000permonth

=$5,000,000

FractionRevenueLoss=(D*(3W-D))/2W2

=(12*(3*50-12))/(2*502)

=0.3312

TotalProfit=[((5,000,000*(1-0.3312))-5,000)/(30+5)]*5

=[(3,344,000-5,000)/35]*5

=95400*5

=$477,000

NRE=$20,000

unitcost=$10

timetomarket=24months(76monthsofmarketwindowremaining)

Revenue=$5,000,000

FractionRevenueLoss=(D*(3W-D))/2W2

=(24*(3*50-24))/(2*502)

=0.6048

TotalProfit=[((5,000,000*(1-0.6048)-20,000)/(10+5)]*5

=130,400*5

=$652,000
