Enter an original price and markdown percent to get the sale price and savings — and, if you add your cost, the margin you keep after the markdown.
A markdown discounts the selling price. Make sure the sale price still clears your cost — deep markdowns can wipe out or reverse your margin. General information.
A markdown cuts the price by a percentage. The trap is margin: a 25% markdown on a product with a 40% margin can leave almost nothing — always check the sale price against your cost before discounting.
Sale price = original × (1 − markdown%) · Margin = (sale − cost) ÷ sale
Same math — both cut the selling price by a percentage. "Markdown" is the retail term for permanently lowering a price or running a sale.
Only until the sale price meets your cost (break-even) — below that you lose money on every unit. Enter your cost above to see the line.
