Calculate your operating margin
Enter revenue, direct costs, operating expenses, and an optional target margin for the same period.
Operating margin normally excludes interest expense, taxes, and
non-operating gains or losses. Use figures from the same accounting
period and classify expenses consistently.
How the Operating Margin Calculator works
The calculator subtracts direct and operating expenses from operating revenue, adds other operating income, and divides operating income by net revenue to measure core operating profitability.
2. Add operating costs
Include cost of goods sold and operating expenses such as selling, administration, research, depreciation, and other normal operating costs.
3. Review profitability
The results show operating income, operating margin, gross margin, cost ratios, and the gap to your target operating margin.
Operating Income
Revenue + Other Operating Income − COGS − Operating Expenses
Operating Margin

Possible meaning
What to investigate
Negative margin
Operating loss
Core operating costs exceed operating revenue. Review pricing, direct costs, staffing, overhead, utilisation, and low-margin products or customers.
Low positive margin
Limited operating cushion
The business is profitable at the operating level, but may have less capacity to absorb demand changes, cost increases, financing costs, or taxes.
Improving margin
Better operating leverage
Rising margin may reflect stronger pricing, a better sales mix, higher utilisation, lower unit costs, or expenses growing slower than revenue.
Declining margin
Profitability pressure
Investigate discounting, wage and supplier inflation, inefficient spending, product mix, customer churn, and revenue growing slower than operating expenses.
Frequently asked questions
Important points for calculating and interpreting operating margin correctly.
What is operating margin?
Operating margin is the percentage of net revenue remaining as operating income after cost of goods sold and operating expenses are deducted. It measures profitability from normal operations.
How is operating margin calculated?
Divide operating income by net revenue and multiply by 100. Operating income is generally revenue minus direct costs and operating expenses, plus other operating income.
What expenses are included in operating expenses?
Operating expenses may include selling and administrative costs, research and development, rent, salaries, marketing, depreciation, amortisation, and other normal operating costs.
Are interest and taxes included in operating margin?
Normally no. Operating margin focuses on operating performance before financing costs and income taxes. Those items are included in pretax or net profit measures.
What is the difference between operating margin and gross margin?
Gross margin subtracts cost of goods sold from revenue. Operating margin also subtracts operating expenses such as selling, administration, research, and depreciation.
What is the difference between operating margin and net margin?
Operating margin measures profit from core operations. Net margin includes interest, taxes, and non-operating items, so it represents final profit after all expenses.
What is considered a good operating margin?
A good margin varies by industry, business maturity, capital intensity, accounting policy, and growth strategy. Compare it with similar businesses and your own history.
How can a business improve operating margin?
Common approaches include improving pricing, reducing direct costs, increasing utilisation, automating work, controlling overhead, improving product mix, and removing unprofitable products, channels, or customer segments.
