Formula
Markup = Margin ÷ (1 − Margin)
Margin = Markup ÷ (1 + Markup) How it works
Margin is measured against the selling price and can never reach 100%. Markup is measured against cost and has no upper limit. That asymmetry is exactly why the two are confused.
Example
A 50% margin is a 100% markup. A 20% margin is a 25% markup. An 80% margin is a 400% markup.
