What is the Profit Margin Calculator?
Profit margin is the percentage of revenue that remains as profit after costs are subtracted. It's one of the most important metrics in business finance — it tells you how efficiently a business converts sales into actual profit, and whether pricing covers costs with room to spare.
The Profit Margin Calculator is a comprehensive tool with six calculation modes: computing profit margin from revenue and cost, finding the right selling price for a target margin, calculating the maximum allowable cost, converting between markup and margin, running break-even analysis, and building a full net margin waterfall from gross to net profit. Results are instant across all modes, and a margin health indicator shows at a glance whether the margin is low, fair, good, or excellent.
Calculation Modes
Profit Margin
Enter revenue and cost to get gross profit, profit margin percentage, markup percentage, cost ratio, and ROI all at once. This is the core mode for evaluating existing pricing or understanding the profitability of a product or service.
Selling Price
Enter your cost and a desired profit margin percentage — the calculator returns the exact selling price needed to hit that margin. Useful when you know your costs and need to set pricing that achieves a specific profitability target.
Find Cost
Enter revenue and a desired margin percentage — the calculator returns the maximum allowable cost to achieve that margin. Useful for procurement, supplier negotiations, or setting cost budgets when the selling price is already fixed.
Markup ↔ Margin Converter
Markup and margin are often confused because they measure different things. Markup is based on cost; margin is based on revenue. This mode converts between the two in both directions, with a reference table covering common markup and margin pairs so you can see the relationship at a glance.
Break-Even Analysis
Enter fixed costs, selling price per unit, and variable cost per unit to find the exact number of units you need to sell before becoming profitable. An optional target profit field shows the units and revenue required to hit a specific profit goal beyond break-even.
Net Profit Margin
Build a full profit and loss waterfall from top to bottom: revenue minus COGS gives gross profit and gross margin, minus operating expenses gives operating profit and operating margin, minus tax and interest gives net profit and net margin. This mode gives the most complete picture of business profitability.
Profit Margin Formulas
Gross profit:
Gross Profit = Revenue − COGS
Profit margin:
Profit Margin (%) = (Gross Profit ÷ Revenue) × 100
Selling price from margin:
Selling Price = Cost ÷ (1 − Margin %)
Markup to margin:
Margin (%) = Markup ÷ (100 + Markup) × 100
Margin to markup:
Markup (%) = Margin ÷ (100 − Margin) × 100
Break-even units:
Break-Even Units = Fixed Costs ÷ (Price per Unit − Variable Cost per Unit)
Example: Revenue of $1,000 and costs of $600 gives a gross profit of $400 and a profit margin of 40%. The same $600 cost with a 40% margin target requires a selling price of $1,000.
Markup vs Margin
This distinction trips up a lot of small business pricing decisions. They are not the same number:
- A 50% markup on a $100 cost produces a $150 price — which is only a 33.3% margin
- A 50% margin target on a $100 cost requires a $200 price — which is a 100% markup
Markup tells you how much you added on top of cost. Margin tells you what percentage of the selling price is profit. Always clarify which metric a pricing conversation is using.
Types of Profit Margin
Gross profit margin measures revenue minus the direct cost of goods sold, divided by revenue. It captures production and procurement efficiency before overhead is considered.
Operating profit margin subtracts operating expenses — rent, salaries, utilities, and other indirect costs — from gross profit. It reflects how efficiently the core business runs before financing and tax effects.
Net profit margin is the bottom line: profit after all expenses, taxes, and interest. It shows what actually remains from each dollar of revenue after everything is accounted for.
What is a Good Profit Margin?
Healthy margins vary significantly by industry:
| Industry | Typical gross margin |
|---|---|
| Software / SaaS | 70–90% |
| E-commerce / retail | 20–50% |
| Restaurants | 60–70% (gross), 3–9% (net) |
| Manufacturing | 25–35% |
| Consulting / services | 50–80% |
| Grocery | 20–25% |
A margin that looks low in isolation might be strong for its industry. Compare against sector benchmarks rather than absolute numbers. The margin health indicator in the calculator uses general thresholds: below 10% is low, 10–20% is fair, 20–40% is good, and above 40% is excellent.

Frequently Asked Questions
What is the difference between profit margin and markup?↓
Margin is based on revenue — it shows what percentage of the selling price is profit. Markup is based on cost — it shows how much was added on top of the cost. A 50% markup on a $100 cost gives a $150 price, which is only a 33.3% margin.
How do I calculate the selling price for a target margin?↓
Use the Selling Price mode. Enter your cost and desired margin percentage and the calculator returns the exact price needed. The formula is: Selling Price = Cost ÷ (1 − Margin %).
What is a good profit margin?↓
It depends on the industry. Software and SaaS businesses typically achieve 70–90% gross margins, while retail and e-commerce ranges from 20–50%. Restaurants often have 60–70% gross margins but only 3–9% net. Always compare against industry benchmarks.
How does the break-even calculator work?↓
Enter your fixed costs, selling price per unit, and variable cost per unit. The calculator divides fixed costs by the contribution margin (price minus variable cost) to find the number of units needed to cover all costs. You can also enter a target profit to see how many units are needed beyond break-even.
What is the difference between gross and net profit margin?↓
Gross margin subtracts only the direct cost of goods sold from revenue. Net margin subtracts everything — COGS, operating expenses, tax, and interest. Use the Net Margin mode to see the full breakdown from revenue down to net profit.
Is the profit margin calculator free?↓
Yes, all six calculation modes are completely free with no account or sign-up required. All calculations happen in your browser and no data is sent to any server.
