Margem de Lucro — Calculadora Online Grátis
Gross margin, markup, health indicator & total profit
The Profit Margin Calculator computes gross margin, net margin, and markup from revenue and cost figures. It distinguishes between margin (profit as a percentage of revenue) and markup (profit as a percentage of cost) — two different metrics that are often confused but produce very different numbers.
Frequently Asked Questions
Sobre Esta Calculadora
Profit margin and markup are two related but distinct metrics that confuse even experienced business people. Margin expresses profit as a percentage of revenue: if you sell something for $100 and it costs $60, your margin is 40%. Markup expresses profit as a percentage of cost: the same $100 sale with $60 cost has a markup of 67%. Both are correct — they just measure from different reference points.
Gross margin is the most commonly tracked metric in retail and manufacturing. It tells you how much of each revenue dollar remains after covering the direct cost of goods sold (COGS) — the more margin you retain, the more money is available to cover operating expenses and generate profit. Net margin goes further by also subtracting operating expenses, taxes, and interest.
This calculator also shows a health indicator: margin benchmarks vary significantly by industry (grocery retail runs on 2–5%, software can be 70–90%), so the contextual color-coding helps you judge whether your margin is strong or concerning for your sector.

Exemplos
Cenário: A restaurant sells a pasta dish for ₹350. Ingredients cost ₹105. No other direct costs.
Resultado: Gross margin = (₹350 − ₹105) / ₹350 × 100 = 70%. Markup = (₹350 − ₹105) / ₹105 × 100 = 233%. The 70% margin must cover rent, labour, and utilities before generating net profit.
Cenário: An e-commerce seller buys a product for $18 and prices it at $45 with free shipping (shipping costs $6).
Resultado: True cost = $24. Gross margin = ($45 − $24) / $45 × 100 = 46.7%. After Amazon fees at 15% ($6.75), net margin drops to ~32% — revealing the real profitability.
