Analysis of monthly
This Excel application
calculates the available budget for each of the 12 months of the current
year. With just a few key figures shown in the Annual overview, your
financial situation becomes clear. Moreover, it is possible to trace
how the amount available in the current month is changed through unplanned
expenses or income.
This Excel workbook was developed for private use. It is regularly
used by the developer himself. Before Excel was available on PCs,
a simple precursor to Excel 85 was designed on an Apple Macintosh
and later on a PC under Windows. Since then, many ideas and improvements
to the present application were incorporated.

Computation of the monthly budget. Calculating and tracking how
the regular income and expenditure throughout the year have an ongoing
affect on the available budget differently for each month. Observing

current month influence the free monthly and yearly budget.
you security when it becomes clear what free budget is available
for each month, and what remains of the budget when unplanned expenditure
and revenues are extrapolated up to the end of the month. If the
figures in a certain month turn 'red', it is easier to deal with
if you can see the previous and anticipated development until the
end of the year.
One Excel sheet
per month, showing scheduled and unplanned amounts.
Excel Version 2000 und above.
The number of
rows for input areas can be extended or reduced by any number. The
upper limit is the Excel row limit.
If rows are
added or removed in one sheet, the changes are applied to all data
sheets at the same time. This is done with the buttons at the top
of the data sheet.
The program is
installed by the "isCalculatorInst.exe" installer, which
is contained in the downloaded .zip file "isCalculatorInst.zip".
After installation the program is available in the folder "C:\IS-Calculator
installed the data sheets are blank. To see an example with user data,
go to the menu "Backup -> Update with backup". A presentation
of user data is then shown. Then close without "Saving" if
you want to start the next session with an empty workbook. A detailed
description follows "Getting Started" in the next paragraph..
A. "Getting Started":
backed-up samples of revenues and expenditure (described above), the
program creates a budget plan for the calendar year. To try out the
functionality, sample data are used from the preinstalled internal backup.
To do this, click the menu "Backup ->Update with backup"
as mentioned above. Confirm the info box note "Update with Backup
in the foreground?" by pressing "Yes".
The actions are then displayed in the foreground. This updates the data
in the "Annual overview" data sheet as well as in "Annual
Planning", "Variance Budgeted" and the 12 monthly data
sheets with the corresponding data from the Backup. The results are
shown in designated areas of the different data sheets. Now when you
view the Annual overview, the changing financial situation becomes clear,
specifically for each of the 12 months..
Note: To begin with empty data sheets after this, you should close
the session without "saving".
B. Implementation uses Windows user functionality within Excel
Entries and changes
have different effects, depending on the data sheet.
All cells that are not prepared for entries or double click sensitivity
are read-only. The gray areas are double click-sensitive.
gray cell areas are designated for input and/or double click
on a gray cell normally inserts an "x". In the "Annual
Budget" data sheet, double clicking a cell under the pane named
income / expenditure categories inserts the number of each calendar
month into the designated cell(s) in the month block to the right
of it, named ”Month due”; whereas double clicking
a single cell of this block removes the number in it (and also removes
the booked amount in the respective monthly data sheets automatically).
When you enter
text into these cells under the pane named income / expenditure
categories in the "Annual Budget" data sheet the same
text is automatically inserted into all relevant monthly data sheets
in which the amount of income and expenditure was additionally
booked automatically for the activated month. In the "Variance
Budgeted" data sheet gray fields are completely protected whereas
white fields are open for input. White columns in the monthly data
sheets are also intended for input.

4. Months data sheets (12)
1. Data Sheet "Annual Overview":
Changing Opening balance bank account:
When using the workbook for the first time, the
“old” balance of your present account statement should
be assigned as the “Opening balance bank account“
in the data sheet Annual Overview (you only need to do this once
for the present year). Then make sure you completed the input in
the Annual Budget data sheet and update the section titled
"Unplanned" in the current monthly data sheet
with the corresponding account transactions by entering its description
and amount. Now you need to activate the amount items in this bank
account statement with an "x" (double
click the respective cell in the column named “booked”
to do so) with the corresponding amounts in the current monthly
the amount of Account balance up-to-date in the
upper right part of the monthly data sheets should be equal to the
“new” balance of your bank account statement.
If you start working with the Calculator workbook in the middle
of a year, rather than at the beginning – which is actually
quite normal - all the "monthly bookings" in the month
block (titled "Month due") of the "Annual Budget"
data sheet must be deactivated by double clicking the month
number in the respective column of the Month due block. You need
to repeat this up to one month before the actual month of the first
bank statement. This gives you correct and distinct values in the
accumulations shown in the upper part of the months data sheets.

/ expenditure categories column activates the inserted amount for
all of the 12 monthly data sheets; double clicking again

double clicking the respective month column in the cell block
titled "Month due".
3. Data Sheet "Variance Budgeted":
