Margin vs. markup — the key difference: both measure profit, but against different bases. Markup is profit as a percentage of cost (profit ÷ cost). Margin is profit as a percentage of the selling price (profit ÷ price). So a $20 profit on an $80 item is a 25% markup but a 20% margin — same dollars, different percentages. Margin is always the smaller number. Everything runs in your browser; nothing is uploaded.
