- Margin = profit ÷ selling price × 100 — a $100 sale costing $40 gives $60 profit, a 60% margin.
- Markup = profit ÷ cost × 100 — the same example is a 150% markup on cost.
- Target margin: price = cost ÷ (1 − margin). A 30% margin on a $40 cost means selling at $57.14.
- Margin is what lands in your pocket per sale; markup is a pricing multiple — the calculator shows both so you can quote either.

Frequently asked questions
What's the difference between margin and markup?
Margin is profit as a share of the selling price; markup is profit as a share of the cost. A 50% margin equals a 100% markup — same $50 profit on a $100 sale that cost $50.
What is the profit margin formula?
Gross margin % = (selling price − cost) ÷ selling price × 100. A $100 product costing $70 has a 30% gross margin.
What is a good profit margin?
It varies by industry: retail is often 2–10% net, software 70–90% gross, restaurants 3–9% net. The healthy question is whether it's stable and covers your fixed costs.
How do I price for a 40% margin?
Divide cost by (1 − 0.40). A $30 cost needs a price of $30 ÷ 0.60 = $50 to leave a 40% margin.
