How this calculator works
The answer does not change between Quick and Detailed. This is the professional finance underneath it — the formula, assumptions and mechanics you can inspect when you want the extra detail.
Markup
Markup = profit ÷ cost.
Margin
Margin = profit ÷ sale price.
Conversion
Margin = markup ÷ (1 + markup). Markup = margin ÷ (1 − margin). The two figures coincide only when sale price equals cost.
