How it works
Sale = original × (1 − discount/100). Markup price = cost × (1 + markup/100). Margin differs from markup: markup is on cost, margin is on selling price.
Examples
120 − 20% = 96 (save 24) 50 + 40% = 70
FAQ
Discount vs markup? Discount is off the original price; markup is added to cost.
Why is 50% markup not 50% margin? Markup 50% on cost 100 → price 150, which is 33.3% margin. Different bases.
Two discounts? Do them sequentially; this tool handles one at a time.
Currency? Plain numbers; add your symbol when reading.
