What This Calculator Does
The Margin Calculator computes profit margin, markup, and gross profit from a selling price (revenue) and cost. Enter the revenue and cost to see the profit amount, margin percentage, and markup percentage. These metrics help evaluate the profitability of a product, service, or business unit.
Formula
Where:
- Revenue = Selling price (the amount received from the sale)
- Cost = Cost of goods sold or the cost to produce/acquire the item
- Profit = Revenue minus cost
Margin expresses profit as a share of the selling price. Markup expresses profit as a share of the cost. Both measure profitability, but from different reference points.
Input Fields Explained
Revenue / Selling Price ($)
The total amount received from selling the product or service. This is the top-line figure before deducting any costs. For a single product, this is the selling price. For a business unit, this is the total revenue.
Cost ($)
The cost of goods sold (COGS) or the cost to produce or acquire the item being sold. This should include direct costs attributable to the product or service. It does not include overhead, operating expenses, or indirect costs.
Example Calculation
You sell a product for $100 that costs $60 to produce.
Profit = $100 − $60 = $40
Margin = $40 ÷ $100 × 100 = 40%
Markup = $40 ÷ $60 × 100 = 66.7%
A 40% margin means that for every dollar of revenue, 40 cents is profit. A 66.7% markup means the selling price is 66.7% above the cost. These two numbers describe the same transaction from different perspectives.
How to Read the Result
The absolute dollar amount earned above the cost. This is revenue minus cost — the gross profit before any other expenses, taxes, or deductions.
Profit as a percentage of the selling price (revenue). This shows how much of each dollar of revenue is retained as profit. A higher margin indicates more profitability per unit of revenue.
Profit as a percentage of cost. This shows how much the selling price exceeds the cost, relative to the cost itself. Markup is commonly used in pricing decisions and retail settings.
Common Mistakes
- Confusing margin and markup. A 50% markup is not the same as a 50% margin. If cost is $100 and you apply a 50% markup, the selling price is $150 and the margin is $50/$150 = 33.3%. Always clarify which metric is being used in pricing discussions.
- Using a universal benchmark for margin. Margins vary dramatically by industry, business model, and scale. Comparing margins across unrelated industries can be misleading. Always benchmark against comparable companies in the same sector.
- Ignoring overhead and operating costs. This calculator computes gross margin, which only considers direct costs. Operating expenses (rent, salaries, marketing) are not included. A healthy gross margin does not guarantee profitability if operating costs are high.
- Not accounting for volume. A high margin on low volume may generate less total profit than a lower margin on high volume. Evaluate margins in the context of sales volume and overall business economics.
- Assuming margin is the same as profitability. Margin is one component of profitability. A business can have healthy margins but still lose money if volumes are too low, fixed costs are too high, or cash flow is poorly managed.
When This Calculator Is Useful
- Evaluating the profitability of a product or service
- Setting selling prices based on a desired margin or markup
- Comparing profitability across different products or services
- Understanding the relationship between cost, price, and margin
- Quick margin calculations during pricing discussions or negotiations
Limitations
- Computes gross margin only — does not account for operating expenses, taxes, or interest
- Uses a simple two-input model (revenue and cost) that does not capture complex cost structures
- Does not handle multi-product scenarios or weighted average margins
- Assumes cost figures are accurate and complete
- Does not factor in volume, fixed costs, or break-even analysis
- This calculator is for educational purposes only and does not constitute business or financial advice

Frequently Asked Questions
What is the difference between margin and markup?
Margin is profit divided by revenue (selling price). Markup is profit divided by cost. For example, if you buy at $60 and sell at $100, the profit is $40. The margin is $40 / $100 = 40%. The markup is $40 / $60 = 66.7%. They measure the same profit from different perspectives — margin relative to the selling price, markup relative to the cost.
What is a good profit margin?
There is no universal benchmark for a good margin. Margins vary significantly by industry, business model, scale, and competitive dynamics. A margin that is healthy in one industry may be unsustainable in another. Compare margins against companies within the same industry and consider factors like growth rate, capital intensity, and competitive positioning rather than relying on a single threshold.
How do I improve my profit margin?
Common approaches include increasing selling prices, reducing cost of goods sold, improving operational efficiency, focusing on higher-margin products or services, negotiating better supplier terms, and reducing waste. The best strategy depends on the specific business, market conditions, and competitive environment.
What is gross margin vs net margin?
Gross margin is revenue minus cost of goods sold (COGS), divided by revenue. It reflects the profitability of core production before overhead. Net margin is net income (after all expenses, taxes, and interest) divided by revenue. Net margin accounts for every cost the business incurs and shows the bottom-line profitability. Both metrics serve different analytical purposes.
Can margin be over 100%?
No. Since margin is calculated as profit divided by revenue, and profit cannot exceed revenue (cost cannot be negative in standard calculations), margin ranges from 0% to 100%. A 100% margin means the cost is zero. Markup, on the other hand, can exceed 100% because it is profit divided by cost.
Does this calculator handle operating margin?
No. This calculator computes gross margin (revenue minus cost, divided by revenue) and markup. Operating margin requires subtracting operating expenses (salaries, rent, depreciation, etc.) from gross profit, which involves additional inputs not supported here. For operating margin, you would need to factor in all operating costs separately.
