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.

Operating margin by industry (Japan Ministry of Finance, Financial Statements Statistics of Corporations, FY2025)

Industry	Operating margin (all sizes; capital under ¥100m in brackets)
Wholesale	2.4% (capital under ¥100m: 2.9%)
Retail	2.9% (capital under ¥100m: 1.5%)
Transportation	5.0% (capital under ¥100m: 1.8%)
Construction	5.7% (capital under ¥100m: 4.6%)
Food service	1.8% (capital under ¥100m: 1.1%)
Manufacturing	5.5% (capital under ¥100m: 3.3%)
Real estate	11.5% (capital under ¥100m: 8.7%)
Information & communications	8.4% (capital under ¥100m: 1.0%)

* Calculated from sales and operating profit in the annual survey of the Ministry of Finance's Financial Statements Statistics of Corporations by Industry (FY2025, excluding finance and insurance, published September 2026; e-Stat time-series data). For all industries the figure is 5.4% (3.1% for companies with capital under ¥100 million). Levels vary widely with company size, business model and the economy even within one industry, so use these as a guide for comparing with companies of the same industry and size.

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 we source and maintain these figures

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

Gross margin is gross profit (revenue minus COGS) divided by revenue. Operating margin goes a step further by also subtracting SG&A expenses like salaries and rent, giving a more accurate picture of the profitability of the business as a whole.

Operating margin reflects profitability from core operations alone, while ordinary income margin also factors in non-operating items such as interest received or paid. Use operating margin to judge core business strength, and ordinary income margin to judge overall performance including financing activities.

This varies a lot by industry, so there is no single answer, but as a general rule, above 5% is often considered solid and above 10% is considered highly profitable. That said, this is a conventional rule of thumb rather than an official standard, so always compare within the same industry.

A negative operating profit means an operating loss — revenue from core operations alone is not covering expenses. Check the breakdown to see whether COGS or SG&A is the bigger burden, and consider reviewing your cost structure.

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.

According to the Ministry of Finance's corporate statistics for FY2025, the operating margin across all industries is 5.4%, and 3.1% for companies with capital under ¥100 million. Wholesale stays around 2%, while real estate is high at 11.5%; information and communications reaches 8.4% across all sizes but only 1.0% among companies with capital under ¥100 million, so the level differs greatly with company size even within one industry. In practice, rather than comparing different industries directly, the margin is best used to compare with companies of the same industry and size, or to track your own trend.
