Profit Margin Calculator measures business profitability, profit as a percentage of revenue, from your revenue and costs, showing both the margin percentage and the profit amount.
The key distinction it surfaces is gross versus net margin. Gross margin (after only the direct cost of goods) reveals how profitable your core offering is; net margin (after all costs, overheads, salaries, tax) reveals what the business actually keeps. A strong gross margin can still erode to a thin net one once overheads are counted, which is exactly why looking at both prevents nasty surprises.
What counts as 'good' is relative: margins vary wildly by industry, from razor-thin grocery retail to high-margin software, so the meaningful comparison is against your sector and your own trend over time. Rising margins generally signal improving efficiency or pricing power.
To improve margin you raise revenue (pricing, mix) or cut costs (suppliers, waste, efficiency), and because gains compound across every sale, even a few points matter. Note this assesses profitability, for pricing to a target margin, the Margin Calculator handles the margin-vs-markup maths. Everything runs in your browser. Pair it with the ROI, Break-Even, and other ToolsMonk business calculators.
Track net margin, not just gross, overheads can turn a healthy gross margin into a thin net one
Judge margins against your industry's norms and your own trend, not an absolute target
