What is a Margin Calculator?
A Margin Calculator helps you understand your pricing by calculating gross profit margin and markup. Simply enter the cost and selling price of a product, and the tool instantly shows your profit per unit, margin percentage, and markup percentage.
How to calculate profit margin manually (the formula)
Gross Margin = ((Selling Price − Cost) ÷ Selling Price) × 100
Markup = ((Selling Price − Cost) ÷ Cost) × 100
Profit = Selling Price − Cost
Example calculation
Cost: $40, Selling price: $60
Profit = $60 − $40 = $20
Gross margin = ($20 ÷ $60) × 100 = 33.33%
Markup = ($20 ÷ $40) × 100 = 50%
This means 33.33% of the selling price is profit, and the price is 50% higher than the cost.
Common mistakes
- Confusing margin with markup — A 50% markup results in a 33.3% margin, not a 50% margin. Using the wrong one can lead to serious pricing errors.
- Calculating margin on cost instead of price — Margin is always a percentage of the selling price, not the cost. Dividing profit by cost gives markup, not margin.
- Forgetting other costs — Gross margin only accounts for direct product costs. Your net margin must also cover operating expenses, marketing, rent, salaries, and taxes.
- Setting prices based on margin alone — While margin is important, also consider competitor pricing, customer willingness to pay, and your overall business strategy.

What is a good profit margin?
Good margins vary by industry. Grocery stores operate on 1–3% margins. Software companies can have 80%+ margins. A healthy margin depends on your business model, volume, and operating expenses.

Increase selling prices, reduce cost of goods sold through better supplier terms or bulk purchasing, improve operational efficiency, or focus on higher-margin products and services.
What is the difference between gross margin and net margin?
Gross margin only considers the direct cost of goods sold. Net margin accounts for all expenses including operating costs, taxes, interest, and overhead. Net margin is always lower than gross margin.
