Profit Margin & Markup Calculator
Calculate profit, profit margin and markup from your cost price and selling price.
Margin is profit as a % of selling price; markup is profit as a % of cost.
What Is a Profit Margin and Markup Calculator?
A Profit Margin and Markup Calculator turns two figures you already know — the cost price and the selling price — into the three numbers that matter for pricing decisions: the profit in rupees, the profit margin as a percentage, and the markup as a percentage. It is a quick way for shop owners, freelancers, traders and online sellers to check whether a price leaves enough room for genuine profit.
Although margin and markup are often used interchangeably in conversation, they are different measurements of the same profit, expressed against different bases. Knowing both helps you set prices confidently, compare products, and avoid the common mistake of assuming a markup percentage equals a margin percentage. The calculator handles the arithmetic so you can focus on the decision.
Profit, Margin and Markup Formulas
The three calculations build on one another:
- Profit = selling price − cost price
- Margin percent = (profit ÷ selling price) × 100
- Markup percent = (profit ÷ cost price) × 100
The key difference is the denominator. Margin measures profit as a share of the selling price, telling you what fraction of each rupee of revenue you keep. Markup measures profit as a share of the cost, telling you how much you added on top of what you paid. Because the selling price is larger than the cost, the margin percentage is always smaller than the markup percentage for the same sale. Margin can never exceed 100 percent, but markup can climb far higher.
Worked Example
Suppose you buy an item for a cost of 1,000 and sell it for 1,500.
Step 1 – Profit: Profit = 1500 − 1000 = 500.
Step 2 – Margin: Margin = (500 ÷ 1500) × 100 = 33.33 percent.
Step 3 – Markup: Markup = (500 ÷ 1000) × 100 = 50 percent.
The same 500 of profit is a 33.33 percent margin but a 50 percent markup, simply because the two percentages are measured against different bases. This is why a product marked up by 50 percent does not give you a 50 percent margin — a point worth remembering when you set target prices.
Margin vs Markup: Which to Use
Both measures are valid, but they answer different questions:
- Use markup when you start from cost and want a quick rule for setting price, for example adding 50 percent to whatever you paid.
- Use margin when you want to know profitability and compare products or report performance, since margin relates directly to revenue.
You can convert between them. To get the selling price from a target margin, divide cost by (1 − margin ÷ 100); a 33.33 percent margin on a cost of 1,000 gives 1000 ÷ 0.6667 = 1,500. To go from markup to margin, use margin = markup ÷ (1 + markup ÷ 100). Keeping these relationships straight prevents underpricing, where a seller mistakes a 25 percent markup for a 25 percent margin and quietly earns less than expected.
Frequently Asked Questions
Both describe the same profit, but margin is profit as a percentage of the selling price, while markup is profit as a percentage of the cost price. For a given sale the margin percentage is always lower than the markup percentage.
First find profit by subtracting cost from selling price, then divide profit by the selling price and multiply by 100. For a cost of 1,000 and a selling price of 1,500, the margin is (500 ÷ 1500) × 100 = 33.33 percent.
Divide the profit by the cost price and multiply by 100. With a cost of 1,000 and a profit of 500, the markup is (500 ÷ 1000) × 100 = 50 percent. Markup is always based on cost, not on the selling price.
No. Because margin is profit divided by selling price, and profit can never exceed the selling price, margin stays below 100 percent. Markup, however, has no such limit and can be several hundred percent.
Divide the cost by (1 minus the margin written as a decimal). To earn a 33.33 percent margin on a cost of 1,000, set the price at 1000 ÷ (1 − 0.3333) = 1,500.
Profit margin should be worked out on figures excluding GST, because GST is collected on behalf of the government and is not your income. Use the cost and selling price net of tax, then apply GST separately at billing.
