Profit Margin, Markup, and Markdown Calculator

How this calculator works

Margin divides profit by selling price; markup divides profit by cost; markdown compares selling price with original price.

Change one assumption at a time to see which inputs have the greatest effect on the estimate.

Worked example

A $60 cost sold for $100 produces $40 profit, a 40% margin, and a 66.67% markup.

Limitations

Actual outcomes can differ because of timing, fees, contracts, taxes, and business-specific accounting choices. Editorial review approved for initial publication; review periodically as assumptions change.
