About the Profit Margin Calculator
A profit margin calculator is a business tool that shows how much of your revenue you keep as profit, expressed as a percentage. It is built for owners pricing products, founders reviewing financial health, managers benchmarking performance, and anyone who needs to understand whether a business or product line is genuinely profitable. Enter your total revenue and total expenses — cost of goods sold, operating costs, or the full picture depending on whether you want gross, operating, or net margin — and the calculator returns your net profit, profit margin percentage, and the equivalent markup. This makes it easy to compare margins across products, periods, or competitors on a like-for-like basis, and to spot where pricing or costs are eroding profitability. By separating margin from markup, the tool also clears up a common source of confusion in pricing decisions. All calculations run locally in your browser, keeping your figures private. For detailed financial planning, tax, or strategic decisions, always consult a qualified accountant or financial adviser.
How to use it
- 1Enter total revenue (sales) for the product or period.
- 2Enter total costs (COGS only for gross margin, or full costs for net).
- 3Calculate to see profit dollars and margin percentage.
- 4Note the markup if shown — it is not the same as margin.
- 5Re-run with target margin to reverse-engineer a required price.
Worked example
revenue $12,000 and costs $8,400 leave $3,600 profit. Profit margin = 3,600 ÷ 12,000 = 30%. Markup on cost is 3,600 ÷ 8,400 ≈ 42.9%. Pricing teams often confuse the two; use margin when comparing profitability and markup when building a price from cost.
How it works
Formula
Profit Margin (%) = (Net Profit ÷ Revenue) × 100
Net Profit = Revenue − Total Expenses
How it works
Enter your total revenue and total expenses (cost of goods sold, operating costs, taxes — whichever level of margin you want to measure) to instantly see your net profit and profit margin percentage.
Who it is for
Business owners pricing products, founders reviewing financial health, managers benchmarking performance, and anyone who needs to understand whether a product line or business is genuinely profitable.
Why it helps
Margin and markup look similar but answer different questions — confusing them leads to underpricing. The tool separates both so you price and benchmark correctly.
Tips for better results
- Decide which margin level you need: gross (COGS only), operating (plus operating costs), or net (everything including tax).
- Benchmark your margin against your industry average — retail often runs 2–10%, software 15–30%+.
- Use markup when setting a price from a cost, and margin when reporting profitability to investors.
- Review margin monthly or quarterly to catch rising costs or pricing drift early.
Common mistakes to avoid
- Confusing margin (profit ÷ revenue) with markup (profit ÷ cost) — a 25% markup is only a 20% margin.
- Comparing gross margin to a competitor's net margin, which are not like-for-like.
- Forgetting to include all expenses at the chosen margin level (e.g. leaving operating costs out of an operating margin calc).
- Treating a one-off revenue spike as a sustainable margin trend.
Frequently asked questions

A:It varies by industry — software and consulting businesses often see 15-30%+, while retail and restaurants typically run 2-10%.
A:Gross margin only deducts cost of goods sold; operating margin also deducts operating expenses; net margin deducts everything, including taxes and interest.
