Operating Margin Calculator (Revenue, COGS & SG&A)
A free tool that instantly calculates your operating margin from revenue, cost of goods sold (COGS), and selling, general & administrative expenses (SG&A) — or directly from operating profit. It measures overall business profitability, distinct from gross margin, and includes an industry benchmark table.
Typical operating margin by industry
| Industry | Typical operating margin |
|---|---|
| Wholesale | Around 1–2% |
| Retail | Around 2–3% |
| Transportation | Around 2–4% |
| Construction | Around 3–5% |
| Food service | Around 3–8% |

What is operating margin calculation
The operating margin calculator is a free tool that lets you calculate "operating margin" — a measure of how profitable your core business is — simply by entering revenue, COGS, and SG&A (or an operating profit figure you already have). While gross margin reflects the profitability of the product or service itself, operating margin captures the profitability of the business as a whole, including indirect costs such as salaries and rent.
If you know the breakdown of your costs, use the "Calculate from revenue, COGS & SG&A" mode. If you already know your operating profit from financial statements, use the "Calculate directly from revenue & operating profit" mode instead.
How to use
- Choose an input method Select "Calculate from breakdown" if you know your COGS and SG&A, or "Calculate directly" if you already know your operating profit.
- Enter your revenue Enter the revenue for the period you want to analyze (monthly, annual, etc.).
- Enter COGS and SG&A, or operating profit Fill in the fields that match the mode you selected.
- Check the result Your operating margin and operating profit are calculated automatically.
Tips for getting more out of it
- SG&A includes every expense not counted in COGS, such as salaries, rent, advertising, and utilities. Missing items here will make your operating margin look higher than it really is, so double-check your figures.
- This tool can also handle a negative operating profit (an operating loss). Use it to see exactly how much your core business is losing.
- In "Calculate from revenue, COGS & SG&A" mode, gross profit is shown alongside the result, so pairing it with a gross margin calculator gives you a fuller picture of your profit structure.
- A healthy operating margin varies widely by industry. Check the benchmark table below and compare your figures against similar companies in your industry.
When this is useful
Estimating the effect of a price rise
**A one per cent fall in cost can do more than a one per cent rise in revenue.** The tool lets you see the difference as figures.
Comparing with others in the same trade
**Comparison across industries says nothing.** Wholesale is structurally low and software structurally high.
Weighing the burden of overheads
Holding cost of sales still and moving only overheads shows how much of them the business can carry.
Looking at profitability by division
**A company in profit overall can conceal divisions that are not.**
Related terms
- Operating profit
- Revenue less cost of sales and overheads. **It expresses the result of the core business alone.**
- Cost of sales
- What was spent directly on buying or making what was sold. **What belongs here is a matter of each company's own policy.**
- Overheads
- Selling, general and administrative expenses: salaries, advertising, rent and the rest of what keeps the business running.
- Gross margin
- Gross profit — revenue less cost of sales — as a proportion. **It looks at the stage before overheads are deducted.**
- Ordinary margin
- Operating profit adjusted for non-operating income and expenses. **The weight of borrowing appears here for the first time.**
- Asset turnover
- How much revenue the assets generated. **A high margin with low turnover still earns little per unit of assets.**
Frequently asked questions
Side Note — Why operating margin reflects your core business strength
Operating margin shows the share of revenue that remains as "operating profit" after subtracting cost of goods sold and SG&A (selling, general & administrative expenses). On the income statement, it sits before non-operating income and expenses (such as interest received or paid, which arise outside core operations) and extraordinary gains or losses (like a one-off gain from selling a fixed asset). Because of that, it is widely regarded as the most honest measure of how much a company can earn purely from its core business.
Gross margin, by contrast, only subtracts the direct cost of purchasing or manufacturing goods, and does not yet account for indirect costs such as salaries or rent. Two companies can both report a "high margin," yet a company with high gross margin but low operating margin is clearly carrying a heavy indirect cost burden. Comparing both figures side by side lets you pinpoint exactly where costs are piling up.
Among small and medium-sized businesses, operating margin levels vary enormously by industry. Wholesalers, which tend to handle large volumes on thin margins, often report just a few percent, while IT and software companies, which have low procurement costs and rely mainly on people-driven services, frequently post margins in the double digits. As a rule of thumb, avoid comparing across unrelated industries — instead track your own trend over time or benchmark against peers in the same industry.
