Cost-plus pricing is the simplest way to set a selling price: take your unit cost and add a fixed markup percentage on top. This calculator returns the selling price, the profit per unit and the resulting profit margin, so you can price products and services with a guaranteed return. It also makes the markup-versus-margin distinction clear, which trips up many sellers.
How it works
The selling price adds the markup to the cost:
profit = cost × (markup ÷ 100) selling price = cost + profit
The margin is then the profit as a share of the selling price, not the cost:
margin = (profit ÷ selling price) × 100
Because the margin’s denominator is the larger selling price, the margin percentage is always smaller than the markup percentage.
Example
A unit cost of 50 with a 40% markup:
profit = 50 × 0.40 = 20 selling price = 50 + 20 = 70 margin = 20 ÷ 70 × 100 ≈ 28.57%
So a 40% markup on cost yields a 28.57% margin on the sale price. Remember that a markup measured against cost always converts to a smaller margin against the selling price. Everything stays in your browser.
