Markup vs. Margin: The Difference in Plain English
Markup and margin both describe profit, but they use different denominators. Markup compares profit with cost. Margin compares profit with selling price. If an item costs $50 and sells for $80, profit is $30. Markup is $30 divided by $50, or 60%. Gross margin is $30 divided by $80, or 37.5%. This difference matters when pricing products because a target margin cannot be produced by simply adding the same percentage to cost. For example, a 50% markup does not create a 50% margin. The practical workflow is to decide which metric your business uses, keep that metric consistent across reports, and use the calculator when converting between the two. When comparing suppliers, markup can make cost-based thinking intuitive. When looking at revenue quality, margin is often easier because it tells you what share of each sales dollar remains before other expenses. Neither figure includes all operating costs, taxes, returns, payment fees, or overhead, so treat the result as a gross pricing metric rather than net profit.
