a. What is the profitability index for the cash flows if the relevant discount rate is 10 percent?
b. What is the profitability index for the cash flows if the relevant discount rate is 17 percent?
c. What is the profitability index for the cash flows if the relevant discount rate is 22 percent?
Solution
Profitability indenx=Present value of future cashflows/Initial investment
a. Present value of a cashflow=Cashflow/(1+r)^n
where
r-intrest rate or discount rate per period-10%
n-number of discounting periods
Thus
Total present value of future cashflows=2700/(1+.1)^1+5400/(1+.1)^2+5000/(1+.1)^3
Solving
Total present value of future cashflows=10673.929
Thus profitability index=10673.929/7400
Thus profitability index=1.442
b
Present value of a cashflow=Cashflow/(1+r)^n
where
r-intrest rate or discount rate per period-17%
n-number of discounting periods
Thus
Total present value of future cashflows=2700/(1+.17)^1+5400/(1+.17)^2+5000/(1+.17)^3
Solving
Total present value of future cashflows=9374.318
Thus profitability index=9374.318/7400
Thus profitability index=1.267
c.
Present value of a cashflow=Cashflow/(1+r)^n
where
r-intrest rate or discount rate per period-22%
n-number of discounting periods
Thus
Total present value of future cashflows=2700/(1+.22)^1+5400/(1+.22)^2+5000/(1+.22)^3
Solving
Total present value of future cashflows=8594.706
Thus profitability index=8594.706/7400
Thus profitability index=1.161
