1. What are disadvantages of Payback Period method used in capital budgeting.
2. A project has an initial cost of $1000 and $450 cash inflow each year for 4 years with a discount rate of 10%. What is its payback period? What is its discounted payback period?
1. payback period is a capital budgeting technique which allows you to find out the time in which your project will be able to cover its initial investment with the given cash flows.
Disadvantages of Payback Period Method -
2. Calculation Of payback period
Given -
Initial Investment = $1000
Cash Flow = $450
Time = 4 Years
Years | Cash Flows | Cumulative Cash flows |
0 | ($1000) | - |
1 |
$450 | 450 |
2 | $450 |
450+450 = $900 |
3 | $450 |
900+450 = $1350 |
4 | $450 |
1350+450 = $1800 |
As we can see that in whole 2 years we got $900 out of $1000 and still $100 is left to be completed which we can get from the next year cash flow (i.e 3rd year)
Thererfore -
= 2 Years + (1000 - 900) / 450
= 2Years + 100 / 450
= 2.22 Years or (2 years 2.6 months)
Calculation Of discount Payback Period
Years | Cash Flows | PV Factor |
Disc. Cash Flow = CF * PV factor |
Cumulative Disc. Cash Flows |
0 | ($1000) |
1 |
(1000) | - |
1 | $450 |
1 / (1+ .10)1 =0.9090 |
409.05 | 409.05 |
2 | $450 |
1 / (1+0.10)2 = 0.8264 |
371.88 | 409.05 + 371.88 = 780.93 |
3 | $450 |
1 / (1+.10)3 = 0.7513 |
338.085 | 780.93 + 338.085 = 1119.015 |
4 | $450 |
1 / (1+.10)4 = 0.6830 |
307.35 | 1119.015 + 307.35 = 1426.365 |
As we can see that in whole 2 years we got $780.93 out of $1000 and still $219.07 is left to be completed which we can get from the next year cash flow (i.e 3rd year)
Therefore
= 2 Year + (1000 - 780.93) / 338.085
= 2 Years + 219.07 / 338.085
= 2 .6479 Years Or 2 Years 7.77 Months
