Cost/Selling price/Markup and Cost/Selling
price/Margin calculations
The Calc application provides a useful function for making
markup and margin calculations, based on figures that you
supply via the keyboard. The way it works is simple: you enter
two of the values that you already know for either the cost,
selling price or markup/margin, and the calculator works out
and displays the missing value. For example, if you enter the
cost and the selling price, it will tell you the percentage markup
or margin based on those two values. If you enter the selling
price and the markup or margin, it will tell you the cost.
