Markup is the percentage added to cost to set a price; margin is the percentage of that price that is profit, and confusing them systematically underprices work.
A 50 percent markup on a $100 cost gives a $150 price and a 33 percent margin. A 50 percent margin on the same cost requires a $200 price. Same percentage. Entirely different outcome. The confusion is common, and the financial damage it causes is quiet: margins erode slowly, no single decision appears catastrophic, and the cause is rarely identified without deliberate examination of the pricing methodology.
The pattern most often appears when a business prices using markup logic but reports performance using margin terminology. The gap between expected and actual profitability accumulates over time, and by the time it is investigated, the problem has compounded across hundreds of transactions.
