Instructions on How to Use the Shopper's-Calculator

To use the calculator, simply enter the cost of each item below the words: Price of Item. Optional, you can also enter the name of each item, under the heading Name of Item. If there is sales tax on your item(s), enter the percentage of the tax under the words: Enter the Sales Tax, if any. If there is a discount in terms of percent, enter it under the words: Enter the Discounts, if any. To obtain your result, left click on the calculation button, or on the tan background, or press the Tab key.

With the Excel and OpenOffice.org versions there is no calculation button, but you can get calculated results by left clicking with the mouse on the background, and also by pressing the enter key or tab key.

With the Excel and OpenOffice.org versions you can save your results, each time you do a calculation, in an Excel Worksheet, by saving with a new file name.

Your result will appear on the upper right of your screen, in red. You will also see calculated results below this: Total with discount, but without sales tax. Below this you will see: Total, without sales tax and discounts. When there is no sales tax or discounts the three calculations will be identical.

Subtraction with the Shopper's-Calculator

If you want to subtract your expenses from your available funds, enter your expenses with a minus sign next to each item, such as rent $ -1200. Enter your funds without any sign.
