Profit Margin Calculator
Calculate profit, profit margin, and markup from cost and selling price.
Apply a markup percentage to cost and see the resulting selling price and profit margin.
Turn a known cost and desired markup into a selling-price estimate, then see the equivalent margin.
Complete the fields and calculate to see a detailed result.
Markup starts with cost. A 40% markup adds 40 cents per cost dollar; it does not create a 40% margin.
Markup amount = cost × markup %. Selling price is cost plus markup. Margin is markup amount ÷ selling price × 100.
A $50 cost with 40% markup adds $20 and produces a $70 price. The resulting margin is 28.57%, because profit is divided by revenue.
The price excludes sales tax and does not test demand, competitors, discounts, returns, overhead allocation, or target net profit.
Markup uses cost; margin uses the higher selling price.
Yes. Price then equals cost and margin is zero.
