Profit margin vs markup

Avoid confusing profit as a share of selling price with markup on cost.

Reviewed 21 September 2026

Direct answer

Markup compares profit with cost. Margin compares profit with selling price. The percentages differ even when cost and selling price are unchanged.

Worked example

A cost of R100 sold for R150 produces R50 profit. That is a 50% markup on cost and a 33.33% margin on selling price.

Limits to check

Gross margin excludes overhead, tax, finance costs and owner compensation unless you include them in the cost model.
