Answer:
NPV 4,648
Payback period 2.88
IRR 22.69%
Simple rate of return 31.33%
Explanation:
Payback period = 2 year + (10,000 – cash in year 1 – cash in year 2)/ cash in year 3 = 2.88 years
Net Present Value = -10000 + 2400/(1+8%) + 4800/(1+8%)^2+ 3,200/(1+8%)^3 + 3,200/(1+8%)^4 + 2,800/(1+8%)^5 + 2,400/(1+8%)^6 = 4,648
Simple Rate of Return = average cash inflow/ investment = ((2,400+4,800+3,200+3,200+2,800+2,400)/6)/10,000 = 31.33%
Internal Rate of Return (IRR): we can use excel to calculate
