Revenue Breakdown
Revenue: 10,000.00
Total Cost: 7,000.00
Gross Profit = Revenue − Total Cost
= 10,000.00 − 7,000.00 = 3,000.00
Gross Margin = (Gross Profit / Revenue) × 100
= (3,000.00 / 10,000.00) × 100 = 30%
Markup = (Gross Profit / Total Cost) × 100
= (3,000.00 / 7,000.00) × 100 = 42.86%A profit margin calculator converts your revenue and cost figures into the key financial ratios that tell you how efficiently your business generates profit. Instead of manually dividing numbers, you get instant results for gross margin, net margin, markup percentage, and break-even revenue — the four metrics that investors, lenders, and business owners use to benchmark financial health.
Whether you're pricing a product, reviewing a quarterly income statement, or comparing your business against industry averages, this tool handles both simple mode (revenue vs total cost) and detailed mode (COGS → gross profit → operating profit → net profit), giving you the complete picture in seconds.
Use Simple mode if you just want a quick margin — enter your total revenue and total cost. Switch to Detailed mode to build out a full income statement with COGS, operating expenses, other expenses, and taxes.
Type in your revenue (total sales) and relevant cost figures. All fields support any currency — select yours from the dropdown. Negative profit is displayed clearly in red so loss-making scenarios are immediately obvious.
The results panel shows your gross margin %, net margin %, markup %, and a colour-coded grade (Excellent / Good / Average / Low / Loss). A stacked bar chart visualises how each cost layer eats into your revenue.

(Revenue − COGS) / Revenue × 100Measures how efficiently you produce or source your product. A high gross margin means you earn a lot on each sale before overhead. Software companies often report 70–85%. Retailers 25–50%. If gross margin is low, improving it means renegotiating supplier costs or raising prices.
Operating Profit / Revenue × 100Gross profit minus all operating costs — salaries, rent, marketing, R&D. This is the best measure of a company's core operational efficiency, unaffected by how it's financed or taxed. A falling operating margin over time signals rising overhead costs eating into your product profits.
Net Profit / Revenue × 100The bottom line — what percentage of every dollar in sales you actually keep after every single expense including taxes and interest. This is the most commonly cited profitability metric. A positive net margin means your business is profitable; a negative one means you're funding growth (or losses) with external capital.
These two terms are often confused, but they measure two different things. Margin is profit expressed as a proportion of the selling price (revenue). Markup is profit expressed as a proportion of the cost. Both use the same numerator (profit) but a different denominator.
| Metric | Formula | Example ($80 cost, $100 price) |
|---|---|---|
| Profit Margin | (Price − Cost) / Price × 100 | 20% |
| Markup | (Price − Cost) / Cost × 100 | 25% |
Confusing margin with markup in pricing decisions is a common and costly mistake. If you want a 20% margin, a 20% markup isn't enough — you need a 25% markup to achieve a 20% margin. Use the Markup figure in the results panel when pricing from cost, and Gross Margin when communicating profitability to investors.
Conversion formula: Margin = Markup / (1 + Markup) | Markup = Margin / (1 − Margin)
Imagine a small e-commerce business with the following annual figures:
| Line Item | Amount |
|---|---|
| Revenue | $120,000 |
| COGS (product cost) | $60,000 |
| Operating Expenses | $30,000 |
| Other Expenses | $5,000 |
| Taxes | $6,250 |
Gross Margin
50%
($120k − $60k) / $120k
Operating Margin
25%
($60k − $30k) / $120k
Net Margin
15.6%
$18.75k / $120k
Enter these numbers in Detailed mode above to verify the results instantly. Try adjusting the operating expenses to see how reducing overhead by just $5,000 would lift the net margin from 15.6% to 19.8%.
Profit margins vary enormously by industry. Use these benchmarks to understand how your business compares. The figures below are typical ranges — outliers exist in every category.
| Industry | Gross Margin | Net Margin |
|---|---|---|
| Software / SaaS | 70–85% | 15–30% |
| E-commerce / Retail | 20–50% | 2–5% |
| Grocery / Supermarket | 25–30% | 1–3% |
| Restaurant | 60–70% | 3–9% |
| Manufacturing | 25–40% | 5–10% |
| Consulting / Services | 50–70% | 10–20% |
| Healthcare | 40–60% | 3–8% |
| Real Estate | 15–25% | 10–20% |
