| Reitrement Model (B) |
|
|
|
|
| In this model, we have THREE decision variables: |
|
|
|
| Question: The dashboard you did as part of homework #2 was static — you took some data from the regional sales database and created a few charts. In this Case, you will develop an interactive dashboard — a graphical user interface to a spreadsheet. Bob (me) will use it to access your model, but he won’t have to worry about all of the messy Excel stuff. For example, Bob might choose his retirement age from a list of drop-down ages or pick and choose his contribution about from a "spinner" that will click up or down one percentage point at a time. All of the calculations are done on other tabs — away from Bob — Bob is presented with a graphical summary (graph(s) / chart(s) / table(s) of summarized numbers. That's the big picture idea. |
|
|
|
|
|
|
|
| Bob's contribution rate (like Model A), the % of his |
|
| Parameters |
|
|
|
|
| final salary that he needs to live on, and his age at retirement |
|
|
| Current Income |
116,000 |
|
|
| The "output" from the model is how old Bob will be when the |
|
|
| Current Savings |
167,000 |
|
|
| retirement funds finally run out. It doesn't assume anyone dies. |
