Calculate profit margin Margin formulas

Verify against your own books — full formula shown.

Profit margin is profit divided by revenue; markup is the same profit divided by cost — and they are never the same number. Gross margin uses direct costs only, contribution margin adds variable fees, operating margin adds overhead, and net margin includes interest and estimated tax. To price for a target margin, divide cost by one minus the margin: a 60 cost at a 40% target needs 60 ÷ 0.60 = 100, not 60 × 1.40 = 84.

What your margin is telling you

Practical reading of the current numbers — planning signals, not verdicts.

Pricing power

Gross margin is 45%. There is room to operate, but fees and overhead will decide how much survives to net profit.

Cost pressure

Direct cost consumes 55% of net revenue. Supplier cost, materials, direct labour, or landed cost is the first line to review.

Overhead pressure

Operating expenses reduce the margin by 26.0 percentage points. Net margin may improve more from overhead control than from small price changes.

Fee leakage

Payment, platform, marketplace, and ad fees consume 6% of net revenue. These scale with every sale, so they cap margin even at higher volume.

Discount & refund leakage

Discounts, refunds, and chargebacks remove 4.8% of gross revenue before any cost is paid. High return rates make a healthy gross margin look weak at the net level.

Break-even safety

Current volume is 1.9× break-even — a reasonable buffer before the model turns loss-making.

Tax & interest drag

Interest (1% of revenue) and estimated tax (4.5%) separate operating profit from net profit. Check both against actual accounting records.

Cash-flow caution

Profit margin does not equal cash in hand. Inventory timing, receivables, loan principal payments, tax timing, and working capital can make cash flow look very different from margin.

How to read your result

The result panel walks revenue down a waterfall: gross margin after direct costs, contribution margin after the fees and shipping that scale with each sale, operating margin after overhead, and net margin after interest and estimated tax. Reading all four together — not just the gross line — is what shows where the money actually goes. The diagnosis cards underneath point at pricing power, cost pressure, fee leakage, refund risk, and break-even safety, and the markup figure sits next to margin so the two are never confused. Switch modes for per-order ecommerce economics, service-quote hourly profit, or SaaS unit economics, then use the target price, discount, break-even, scenario, and sensitivity tools to stress-test the number before you download the workbook.

Profit margin formulas

Margin

Margin % = Profit ÷ Revenue × 100

Denominator is REVENUE.

Markup

Markup % = Profit ÷ Cost × 100

Denominator is COST — always larger than margin.

Target price from margin

Price = Cost ÷ (1 − Margin)

Division, not multiplication. 100% margin is impossible.

Worked example

Selling price ₹2,000, product cost ₹900, packaging ₹50, shipping ₹120, payment fee 2%, marketplace fee 10%, ad cost ₹250, return allowance 5% (full loss). Product-cost-only, the sale looks like a 55% margin (2,000 − 900 = 1,100). But net order revenue after the return allowance is ₹1,900; direct costs are 1,070; fees and ads add 40 + 200 + 250 = 490 — leaving a contribution profit of ₹340 per order, an 17.9% contribution margin. Fees, ads, shipping, and returns consumed the difference between the product-cost view and the real number. This is why the calculator separates gross margin (direct cost only) from contribution margin (every cost that scales with the sale) instead of reporting one blended figure.

Assumptions

Gross margin uses direct costs/COGS; contribution margin adds variable fees; operating margin adds operating expenses; net margin adds interest and estimated tax — all divided by net revenue.
Estimated tax = max(0, pre-tax profit) × your rate, or a custom amount — a planning simplification, not a jurisdiction-specific computation.
When "GST/VAT included in price" is selected, the tax portion (gross − gross ÷ (1 + rate)) is carved out of revenue as a pass-through, so collected tax never inflates margin.
Break-even assumes constant price, variable cost, and genuinely fixed costs; scenarios apply simple percentage shifts; annualised rows assume the period repeats.
SaaS LTV and CAC payback use a steady-state churn shortcut (new customers ≈ customers × churn), not cohort analysis.

Limitations

Not accounting software: no depreciation, amortisation, inventory valuation, accrual timing, working capital, or loan principal modelling.
No jurisdiction-specific tax compliance — income tax, GST/VAT filing, and sales-tax nexus rules are out of scope.
Benchmark bands used inside the tool are soft planning ranges, not statistics or guarantees.
Profit margin does not equal cash flow — inventory, receivables, tax timing, and debt payments move cash independently of margin.

For VAT/GST price arithmetic see the VAT/GST calculator; for income-side taxes see the income tax calculator; for ad-spend break-even see the break-even ROAS calculator.

Frequently asked questions

What is a profit margin calculator?

A tool that estimates how much of your revenue remains as profit after selected costs, expressed as a percentage. This one calculates gross, contribution, operating, and net margin, plus markup, target price, discount impact, break-even, scenarios, SKU comparison, and a downloadable XLSX workbook.

How do I calculate profit margin?

Subtract costs from revenue to get profit, then divide profit by revenue and multiply by 100. With 10,000 revenue and 6,000 cost: profit 4,000, margin 4,000 ÷ 10,000 = 40%.

What is the difference between margin and markup?

Margin divides profit by the selling price; markup divides the same profit by the cost. A 40 profit on a 100 sale with 60 cost is a 40% margin but a 66.7% markup. They are never the same number except at zero.

Should GST/VAT/sales tax be included in revenue?

Generally no — tax collected from customers is a pass-through liability owed to the tax authority, not income. If your selling price includes GST/VAT, use the "tax included" option and the calculator carves it out: net revenue = gross ÷ (1 + rate).

What is a good profit margin?

It depends on the business model. As soft planning bands: under 5% net is very thin, 5–10% thin, 10–20% moderate, 20–35% healthy, above 35% high. But a 4% net margin can be normal for retail and weak for consulting — use the business-type selector for context, and treat all bands as orientation, not verdicts.

Business planning disclaimer

This profit margin calculator and its XLSX workbook are for education and planning only. They are not financial, accounting, tax, legal, investment, lending, or business advice, and they are not accounting software. Estimated tax is a simplified planning input, not a filing calculation; GST/VAT treatment depends on jurisdiction and accounting method. Actual profit and cash flow can differ because of inventory timing, refunds, chargebacks, payment delays, working capital, loan payments, depreciation, and accounting method. Verify results with your actual books and a qualified professional before making financial decisions.

How to Calculate Profit Margin, Markup, and Break-Even Correctly

Margin, markup, and break-even are not the same thing — worked examples show why a 40% markup is only a 28.6% margin, not 40%.
