Margin vs markup
They’re not the same number: a 50% markup is a 33.3% margin. Enter any two of cost, price, margin or markup and see all four together, decimal-exact.
Same profit, two bases
The profit on a sale is one number. Markup expresses it as a fraction of what you paid (profit ÷ cost); margin expresses it as a fraction of what you charged (profit ÷ price). Because the selling price is always larger than the cost, the margin percentage is always lower than the markup — mixing them up quietly erodes profitability.
Enter your own numbers above and the calculator shows cost, price, profit, margin and markup at once.
