| Discounted payback is a variant of the [[payback]] method of investment appraisal.
| | (MMF). A managed fund which invests in money market instruments. |
|
| |
|
| Under discounted payback, the amounts of money arising in different time periods are discounted to their present values.
| | Some money market funds are structured as 'liquid' money market funds, designed to be lower risk managed funds by - among other features - investing only in liquid money market instruments of the highest credit quality. |
| | |
| | |
| '''Example''' | |
| | |
| A proposal requires an initial investment of $100m at Time 0 years,
| |
| | |
| and will then pay out annual amounts of $10m, $20m, $30m, $40m, $50m and $60m,
| |
| | |
| at future Times 1 to 6 years respectively.
| |
| | |
| The relevant cost of capital is 10% per year.
| |
| | |
| | |
| The cumulative discounted net cash flow and discounted payback period are calculated as follows:
| |
| | |
| <u>Discounted cash flows:</u>
| |
| | |
| '''Time 0:''' (100) x 1.10<sup>0</sup>
| |
| | |
| = $(100)m.
| |
| | |
| | |
| '''Time 1:''' 10 x 1.10<sup>-1</sup>
| |
| | |
| = $9.09m.
| |
| | |
| | |
| '''Time 2:''' 20 x 1.10<sup>-2</sup>
| |
| | |
| = $16.53m.
| |
| | |
| | |
| '''Time 3:''' 30 x 1.10<sup>-3</sup>
| |
| | |
| = $22.54m.
| |
| | |
| | |
| '''Time 4:''' 40 x 1.10<sup>-4</sup>
| |
| | |
| = $27.32m.
| |
| | |
| | |
| '''Time 5:''' 50 x 1.10<sup>-5</sup>
| |
| | |
| = $31.05m.
| |
| | |
| | |
| | |
| <u>Cumulative discounted cash flows:</u>
| |
| | |
| '''Time 0:''' (100).
| |
| | |
| | |
| '''Time 1:''' (100) + 9.09
| |
| | |
| = $(90.91)m.
| |
| | |
| | |
| '''Time 2:''' (90.91) + 16.53
| |
| | |
| = $(74.38)m.
| |
| | |
| | |
| '''Time 3:''' (74.38) + 22.54
| |
| | |
| = $(51.84)m.
| |
| | |
| | |
| '''Time 4:''' (51.84) + 27.32
| |
| | |
| = $(24.52)m.
| |
| | |
| | |
| '''Time 5:''' (24.52) + 31.05
| |
| | |
| = +$6.53m.
| |
| | |
| | |
| The initial investment has paid back by the end of 5 years, so the payback period to the nearest whole year is 5 years.
| |
| | |
| It is also possible to calculate a more refined estimate using interpolation between 4 years and 5 years. Interpolation assumes that the cash flows arise evenly over the course of the 5th year.
| |
| | |
| | |
| This method removes some of the problems of the simple payback method. But it still leaves significant problems and simplifying assumptions.
| |
|
| |
|
| | Other money market funds seek to provide higher average expected income through a longer dated, higher risk and less liquid portfolio. |
