An investment project costs $17,200 and has annual cash flows of $4,200 for six years. |
a. What is the discounted payback period if the discount rate is zero percent? |
|
b. What is the discounted payback period if the discount rate is 3 percent? |
|
c. What is the discounted payback period if the discount rate is 20 percent? |
|
a. The discounted payback period is computed as shown below:
= Investment / Annual cash flow
= $ 17,200 / $ 4,200
= 4.10 Approximately
b. The discounted payback period is computed as shown below:
Cumulative discounted cash flows from year 1 to year 4 is computed as follows:
= $ 4,200 / 1.031 + $ 4,200 / 1.032 + $ 4,200 / 1.033 + $ 4,200 / 1.034
= $ 15,611.81329
Cumulative discounted cash flows from year 1 to year 5 is computed as follows:
= $ 4,200 / 1.031 + $ 4,200 / 1.032 + $ 4,200 / 1.033 + $ 4,200 / 1.034 + $ 4,200 / 1.035
= $ 19,234.77019
It means that the discounted payback period lies between year 4 and year 5, since the initial investment of $ 17,200 is recovered between them. So, the discounted payback period will be computed as follows:
= 4 years + Balance investment to be recovered / Year 5 discounted cash flow
= 4 years + [ ($ 17,200 - $ 15,611.81329) / ( $ 4,200 / 1.035) ]
= 4 years + $ 1,588.18671 / $ 3,622.956894
= 4.44 years Approximately
c. The discounted payback period is computed as shown below:
Cumulative discounted cash flow from Year 1 to Year 6 is computed as follows:
= $ 4,200 / 1.201 + $ 4,200 / 1.202 + $ 4,200 / 1.203 + $ 4,200 / 1.204 + $ 4,200 / 1.205 + $ 4,200 / 1.206
= $ 13,967.14 Approximately
As can be seen the initial investment of $ 17,200 is not recovered, hence the correct answer is option of Never.
