May be found here. Open Office’s Calc spreadsheet. What is the cost of obtaining the software? The cost of downloading and installing it, it is free for the download.
In addition, you can open and save Excel spreadsheets. Compatibility is not 100% but darned near, the only time I have compatibility problems is when attempting to open Excel sheets with macros.
The formulas are not quite the same, but all is close enough you can readily transfer your knowledge of Excel to Calc.
What you are looking at in the above screen grab is the summary sheet from my expenditures spreadsheet. There are roughly 14 sheets, each sheet tracks expenditures by category, for example there are sheets for utility, grocery, and clothing expenditures.
The summary sheet gives at a glance the grand total, and totals broken down by category, and month.
Partially visible are the numbers rendered into percentages against the particular total and not visible are pie charts, both year and for January. Of course, as the year progresses I will create pie charts for each month.
Next posting I will show a pie chart. My Lord, I can almost see this transforming itself into a full fledged web-based application.
