How to Use
Profit Margin Formula
Profit margin (%) = profit ÷ selling price × 100
Profit = selling price − cost
Selling price = cost ÷ (1 − margin)
Cost = selling price × (1 − margin)
Example: a cost of 700 sold at 1,000 gives a profit of 300 and a margin of 30%. Enter the cost and price in row 1 and the tool runs this calculation automatically.

Frequently Asked Questions
What is the difference between margin and markup?
Margin is profit as a percentage of the selling price: (price − cost) ÷ price × 100. Markup is profit as a percentage of the cost: (price − cost) ÷ cost × 100. This tool calculates margin, so a cost of 700 sold at 1000 gives a 30% margin (which is about a 43% markup).
Is this the same as a gross profit margin calculator?
Yes. The margin calculated here is the gross profit margin: it subtracts only the cost of the item (selling price − cost) and does not account for operating expenses such as labor or rent. The Profit column shows the gross profit amount.
What is the profit margin formula?
Profit margin (%) = (selling price − cost) ÷ selling price × 100. For example, a cost of 700 and a price of 1000 give a profit of 300 and a margin of 30%. Enter the cost and price and the tool calculates this automatically.
How do I find the selling price from a target margin?
Selling price = cost ÷ (1 − margin). To reach a 30% margin on a cost of 700, the price is 700 ÷ 0.7 = 1000. Use the second row, “Find Price,” and enter the cost and target margin.
How are cost ratio and profit margin related?
Cost ratio (%) = cost ÷ selling price × 100, and together with the margin it always adds up to 100% (cost ratio = 100 − margin). A 30% margin means a 70% cost ratio. If you have a target cost ratio, enter 100 minus that value as the margin and the tool returns the matching price or cost.
