In investment analysis, you can use the calculator
to enter cost and benefit streams. You can save the calculator results
directly to a time period for a given stream with a cost or benefit
selected in the open model.
The result
of the calculation is saved to the financial model. You can use the
same calculator in multiple time periods on the same cost or benefit
stream with different parameters. By doing so, you can model changing
inputs and requirements over the life of the project.
Procedure
- In investment analysis, click the Calculator tab.
- Move the timeline slider to a time period; for example,
2011 Q1. The save button changes to reflect the selected time period.
- Click Save results to YYYY Qn. The time period on the timeline is in bold, which indicates
that the input is written to the model. You can also retrieve the
tape for a previously saved time period by moving the time slider
to that time period.
- To model changing inputs, edit the model parameters and
select a new time period.
- Click Save results to YYYY Qn. If the result is already stored in that time period, the results
and model are overwritten with the new results and model. After the
calculator results are saved, the data is linked to the specific tape.
- To reload a specific tape, on the graph of the financial
model, click the data point.
- To override the calculator input values, edit the relevant
tape.
- To disassociate a tape from a time period, use the timeline
slider to select the time period, and click Delete results
from YYYY Qn.
Note: - When a calculator result is associated with a time period, you
can edit the data in the tape only. You cannot edit that data by using
the graphical or spreadsheet entry methods.
- When you switch to calculator method from another entry method,
you can run the simulation again and save the new results to the cost
or benefit stream.
- If you remove a data point from the graphical or spreadsheet views,
the calculator model that is associated with that point is also removed.
