甲方案没说项目建设期多久,按建设期2年算.
甲方案:
每年折旧=(100-5)/5=19
N0= -100-50= -150
N1=0
N2=0
N3~N6=(90-60)*(1-33%)+19=39.1
N7=39.1+5+50=94.1
净现值= -150+ 39.1*(P/A,10%,4)*(F/P,10%,2)+94.1*(F/P,10%,7)= -150+ 39.1*3.169*0.826+94.1*0.513= 0.6212
乙方案:
每年折旧=(120-8)/5=22.4
每年摊销=25/5=5
N0= -120-25-65= -210
N1=5*33%=1.65
N2=1.65
N3=(170-80-22.4-5)*(1-33%)+22.4+5= 69.342
N4=69.342
N5=69.342
N6=(170-80-22.4)*(1-33%)+22.4= 67.692
N7=67.692+8+65=140.692
净现值= -210+1.65/(1+10%)+1.65/(1+10%)^2+69.342/(1+10%)^3+69.342/(1+10%)^4+69.342/(1+10%)^5+67.692/(1+10%)^6+140.692/(1+10%)^7= 45.7864
甲乙方案净现值均大于零,都可行.
