Determining Sale Price After a Markdown

In markdown calculations, the original selling price is the base, or 100%. After a markdown is subtracted from that price, the new price represents (100% − Markdown percent) of the original price.

To find the new sale price after a markdown, we use the familiar percentage formula, Portion = Rate × Base, where the sale price is the portion, the original price is the base, and (100% − Markdown percent) is the rate.
