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.
