Three mutually exclusive investment alternatives are being considered. The estimated cash flows for each alternative are given below. The study period is 30 years and the firm's MARR is 17% per year. Assume repeatability and reinvestment of positive cash balances at 17% per year.
a. What is the simple payback period for Alternative 1?
b. What is the annual worth of Alternative 2?
c. What is the IRR of the incremental cash flows of Alternative 2 compared to Alternative 1?
d. Which alternative should be selected?
Alt. 1 Alt. 2 Alt. 3
Capital Investment -25,000 -60,000 -45,000
Annual Costs -12,000 -30,000 -20,000
Annual Revenues 28,000 57,500 38,000
Market Value at End of Useful Life 9,000 9,000 9,000
Useful Life, years 5 5 6
IRR 59.9% 37.7% 34.4%
Calculation of Net Annual Cash Flow:
Particular | Alternative1 | Alternative2 | Alternative3 |
Annual Revenue | 28000 | 57500 | 38000 |
Annual Cost | 12000 | 30000 | 20000 |
Net Cash Flow | 16000 | 27500 | 18000 |
(a)
Calculation of Payback Period(PBP):
Payback period is the period in which the Cost of a project is recovered from the revenues of the projects.
Formula:Payback period(in case of equal cash flows)=Cost of a project/Annual Cash Flows
PBP(Alternative1)=25000/16000
=1.5625 Years or 1year 7months approx
(b) Calculation of Annual worth of Alternative2:
Annual worth is the equivalent annual net cash flow of the cash flows to be received throughout the life of a project.
IRR is the annual rate of return of the cash flows of a project. In other words IRR is the rate which if used for discounting the cash flows, equates the net cash flows(including scrap) to the intial investment or the cost of the project.
We know that
Present value of cash flows=Annual Cash flows*PV factor of annuity @ r rate for n periods
PV factor of annuity= [(1+r)^n-1] / [(1+r)^n*r]
PV factor of annuity for 37.7% for 5 years=[(1+.377)^5-1] / [(1+.377)^5*.377]
=2.116737
Again
Present value of cash flows=Annual Cash flows*PV factor of annuity @ r rate for n periods
60000=Annual Cash flows*2.116737
Annual Cash flows=60000/2.116737
=28345.5
(c) Calculation of incremental Cash flows:
Particular | Alternative1 | Alternative2 | Incremental(Alt2-Alt1) |
Annual Revenue | 28000 | 57500 | 29500 |
Annual Cost | 12000 | 30000 | 18000 |
Net Cash Flow | 16000 | 27500 | 11500 |
Cost of Project | 25000 | 60000 | 35000 |
Incremental Cost=Incremental Net Cash Flows*PV factor of annuity at r rate for 5 years
35000=11500*PV factor of annuity
PV factor of annuity=35000/11500
=3.0435
Look 3.0435 in the 5th year's column in the PV of annuity table. 3.0576(which is nearly equal to 3.0435) is before 19% rate hence IRR should be between 19% to 20%.
We can find exact IRR by using IRR functin of excel:
Year | Cash Flow |
0 | -35000 |
1 | 11500 |
2 | 11500 |
3 | 11500 |
4 | 11500 |
5 | 11500 |
IRR | 19.21% |
Formula: =IRR(B2:B7)
We could find Exact IRR without using excel as well by using following formula:
Hence the result is same as we calculated using excel.
Note: NPV for both the rates have been calculated by discounting the incremental cash flows(i.e.11500) by repective rates and deducting Incremental Cost of investments from the Present Value of Cash flows.
(D)
Project A has highest IRR(59.9%) hence Project A should be selected.
