Ordinary Income Margin Calculator (Operating Profit & Non-Operating Income/Expenses)
A free tool that instantly calculates ordinary income and ordinary income margin from operating profit (or revenue, COGS & SG&A) plus non-operating income and non-operating expenses. Unlike operating margin, it measures overall profitability including financing activities.
What is ordinary income margin calculation
The ordinary income margin calculator is a free tool that lets you calculate "ordinary income margin" — a measure of how profitable a company's regular business activity is — simply by entering operating profit (or revenue, COGS, and SG&A) along with non-operating income and expenses. While operating margin reflects profitability from core operations alone, ordinary income margin captures the profitability of the company as a whole, including the results of financing activities such as interest received and paid.
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.
- Enter non-operating income and expenses Enter non-operating income such as interest and dividends received, and non-operating expenses such as interest paid.
- Check the result Your ordinary income margin and ordinary income are calculated automatically.
Tips for getting more out of it
- Non-operating income includes items like interest received, dividends received, and foreign exchange gains, while non-operating expenses include interest paid and foreign exchange losses — both are financing-related items unrelated to core sales.
- This tool can also handle a negative ordinary income (an ordinary loss). Even with a positive operating profit, a heavy interest burden can push ordinary income negative.
- Pairing this with an operating margin calculator lets you compare core business profitability (operating margin) against overall profitability including financing activities (ordinary income margin).
- Ordinary income margin is a key metric in bank loan reviews and corporate credit ratings. If the gap versus operating margin is large, review the details of your non-operating income and expenses.

Frequently asked questions
Side Note — Why ordinary income margin reflects a company's true strength
Ordinary income margin shows the share of revenue that remains as "ordinary income" after adding non-operating income to operating profit and subtracting non-operating expenses. On the income statement, it sits before extraordinary gains and losses (such as a one-off gain from selling a fixed asset or a loss from a disaster), which are limited to that year only. Because of that, ordinary income is widely regarded as the figure that best represents the profit generated by a company's regular yearly business activity. In Japan, this figure is also emphasized in tax filings and bank loan reviews.
While operating margin reflects profitability from core operations alone, ordinary income margin captures the profitability of the company as a whole, including the burden of interest on borrowings and the returns from any invested assets. Two companies with identical operating margins can end up with very different ordinary income margins: one carrying heavy debt and interest payments will see its ordinary income margin fall below its operating margin, while one earning solid interest and dividends from invested assets may see the opposite.
In practice, small and medium-sized businesses can catch changes in their financial health early by tracking the gap between operating margin and ordinary income margin (the size of the non-operating balance) each period. A sudden widening of that gap can signal rising debt or higher interest rates, which is a good trigger to review your financing strategy.
