Definition and formula
Net margin (or net margin rate) measures a company's final profitability. It indicates what proportion of revenue turns into net income after all charges.
Formula: Net margin = Net income / Revenue × 100
Net income is the profit after deducting all charges: production costs, overheads, depreciation, financial charges (interest) and corporate tax. It is the last line of the income statement — hence its nickname, the bottom line.
The margin cascade
Net margin is the final result of a cascade of intermediate margins. Understanding at which level profitability erodes is as important as the final figure:
The gap between EBITDA margin and net margin is telling: a large gap means high depreciation (capital-intensive), heavy financial charges (debt) or a heavy tax burden.
Benchmarks by sector
Net margin varies considerably by sector. Comparing a company to the whole market makes no sense — only a sector comparison is relevant.

How to interpret a net margin
Three questions to ask when looking at a net margin:
- Is it in line with the sector? A 6% margin for a retailer is good; for a SaaS publisher, it is inadequate.
- What is the trend over 3-5 years? A steadily improving margin signals positive operating leverage — growth is spreading fixed costs.
- Is it volatile or stable? A volatile margin indicates exposure to cycles (commodities, rates, currency). A stable margin indicates a recurring, predictable model.
Moat signal: a net margin structurally above the sector average over 5+ years is one of the best indicators of a durable competitive advantage. Companies without a moat see their margin converge towards the average under competitive pressure.
