An investment project costs $18,700 and has annual cash flows of $4,000 for six years. Required : (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 6 percent? (c) What is the discounted payback period if the discount rate is 22 percent?
Answer :
a) 4.68 Years
b) 5.66 Years
c) Never
Notes:
a) Discounted Payback Period =
( Last Year with a Negative Cumulative Cash Flow ) + [( Absolute Value of negative Cumulative Cash Flow in that year)/ Total Present Cash Flow in the following year)]
At Zero Percent :
Discounted Payback Period =
= 4+(2700/4000)
= 4.68 Years
Working:
| Cash Flow | Discounting Factor ( 0%) | Present Value (Cash Flow * Discounting Factor) | Cumulative Cash Flow (Present Value of Current Year+ Cumulative Cash Flow of Previous Year) | |
| 0 | -18,700 | 1 | -18,700.00 | -18,700.00 |

| 6 | 4,000 | 1.0000 | 4,000.00 | 5,300.00 | 
b) At 6% ,
Discounted Payback Period =
( Last Year with a Negative Cumulative Cash Flow ) + [( Absolute Value of negative Cumulative Cash Flow in that year)/ Total Present Cash Flow in the following year)]
= 5+(1850.54/2819.84)
= 5.66 years

c) At 22% ,
Discounted Payback Period =
( Last Year with a Negative Cumulative Cash Flow ) + [( Absolute Value of negative Cumulative Cash Flow in that year)/ Total Present Cash Flow in the following year)]
= Never
