hen you prepare budgets or other financial
analyses built on future assumptions, you usually
have to try out various estimates before you can
come up with the scenario that meets your needs.
In a typical situation, you even may need to
print the numerous analyses so you dont
lose track of which versions are based on which
assumptions. In short, it can be a tedious task.
Fortunately, there is a way, applying a few
adjustments in Excels powerful
what-if tool Scenario Manager,
to make the task more effective and less onerous.
Lets walk through the process so you can
see how to use the tool.
So you can work along with me
as I set up the analyses, I suggest you download
the model budget I prepared (see exhibit 1) for PQR Co. from www.aicpa.org/download/pubs/jofa/2004_09_weisel-budget.xls. All numbers have been rounded.
As youll
see I prepared the budgeted quarterly income
statement with several initial assumptions.
PQRs management wants to
see how various assumptions will affect results.
For example, what will happen if sales growth
slows to 2.5% or 2% while cost of sales continues
at a 3% rate? And will 3.5% sales growth be
sufficient to offset a targeted increase in
advertising?
To begin the exercise, assume
gross sales and cost of sales will rise 3% each
quarter. The spreadsheet has the appropriate data
and formulas to use that information to calculate
net operating income, gross profit ratios and
return on sales.
Now lets put Scenario
Manager to work. With the spreadsheet
open, click on Tools and Scenarios
to evoke the Scenario Manager
dialog box (exhibit 2).
Click on the Add
button, which brings up the Add Scenario
box (exhibit
3).
To add a scenario you must
input its name and identify the cells you will
allow to be changed by new information. Once we
get under way, Ill show you how to specify
the scenario values.
In addition to the original
assumption of a 3% sales growth rate, we also
will be examining the impact of 2.5%, 2% and 1.5%
growth rates.
In the Add Scenario screen,
create a name for the first scenario, such as
2.5% growth rate, and type it in the Scenario
name box. Now click in the Changing
cells box and backspace to delete any
existing references. Click on cell I5
(the sales-growth-rate assumption) and note that
Excel automatically populates it with all the
appropriate references. Hold down the Ctrl key
and click on cell I11 (a
cost-of-sales growth rate assumption). Continue
holding down the Ctrl key and click on cells B16, C16, D16 and
E16 so we can see the
quarterly impact on advertising expenses. In
order to provide some additional documentation
about what Im doing, Ive added a
description of this scenario in the Comment
box. You can add your own details here; just
click in the Comment box and
type away. The Add Scenario box
now should resemble exhibit 4.
Click on OK
to move on to the third task: specifying scenario
values in the new screen that opens (see exhibit 5). The only value we will alter
initially in the Scenario Values
box is the first itemsales growth rate.
Click in the first box and type in .025
and click on OK.
The Scenario Manager screen
now should resemble exhibit 6.
To create additional scenarios,
simply repeat the above process and specify the
appropriate value for sales growth rate. We have
already specified the cells allowed to change so
we do not need to repeat that step. After you add
the scenarios for 2% and 1.5% growth rates, the
completed Scenario Manager
should resemble exhibit 7.
GETTING IT ALL TOGETHER
Now well
generate a report that will summarize the three
scenarios weve just created. From the Scenario
Manager dialog box, click on Summary.
Leave the Report type as Scenario summary
and click in the Result cells
box. You may need to backspace to delete any
existing cell references. While holding down the
Ctrl key, click on cells F7, F23, F25 and F26.
The Scenario Summary dialog box
now will look as illustrated in exhibit 8.
Now the payoff
for your efforts: Click on OK in
the Scenario Summary dialog box
and Excel will generate a new worksheet tab, as
shown in exhibit 9 with
a report summarizing our initial budget as well
as the three scenarios.
Across the top
of the report we find a listing of the current
values as well as each of the three scenarios we
specified. The report is divided into two main
sections. The first identifies each of the cells
we permitted to change as well as their values.
The second section contains the result cells we
asked for: net sales, net operating income, gross
profit ratio and return on sales. We can see, for
example, that a sales growth rate of 1.5% would
reduce net operating income from its current
projection of $214,000 to $124,000. The single
report provides an excellent comparison of
multiple assumptions and documents those
assumptionseliminating the need to sort
through stacks of paper.
You can add and subtract
scenarios from Scenario Manager
at will. With the cells previously identified as
allowed to change, we easily can create a
virtually unlimited number of scenarios with
various combinations of assumptions. For example,
following the steps identified previously,
Ive created two additional scenarios
assuming the company increased advertising to
$110,000 quarterly and the resulting sales growth
rate and cost-of-sales growth rates are 3.5% and
4%, respectively.
For convenience, Ive
temporarily hidden columns E through G (the 2.5%,
2%, and 1.5% growth rate assumptions) so the two
new scenarios fit in the screen. The ability to
hide or unhide columns gives the user more
flexibility in managing and presenting the
reports. The resulting report is shown in exhibit 10. Here we can see a 4% growth rate is
necessary to effectively offset the cost of
advertising, yielding a small increase in net
operating income from $214,000 to $219,000.
With a little
work up front, Scenario Manager
can significantly improve your ability to create
concise reports comparing multiple
what-if analyses. Users should note
that Excel limits the number of cells allowed to
change to 32. The number of scenarios that can be
created, however, is virtually unlimited. This
should permit analysts sufficient flexibility to
create as many what-ifs as needed.
