Operating Income (EBIT) Calculator
The operating income calculator finds the profit a business earns from its core operations, before interest and taxes, a figure also known as EBIT. The method follows the income statement directly: operating income equals gross profit minus operating expenses. Gross profit is revenue less the cost of goods sold, and operating expenses are the running costs of the business such as wages, rent, marketing, insurance, depreciation and administration, excluding interest and income tax. Because it strips out how the business is financed and taxed, operating income shows how profitable the underlying operations really are, which makes it useful for comparing companies and tracking efficiency over time. In most cases operating income and EBIT are the same; a difference arises only when a company has non-operating gains or losses that EBIT includes. Enter your own gross profit and operating expenses to measure operating profit, work out an operating margin, or check a line on an income statement. Every figure here is computed deterministically from the formula shown in full below, with a worked example that reconciles exactly to the calculator so you can follow each step and trust the result rather than relying on an estimate of operating profit.
Operating income equals gross profit minus operating expenses: EBIT = gross profit - operating expenses. With gross profit of $500,000.00 and operating expenses of $300,000.00, operating income is $200,000.00, the profit before interest and taxes.
Operating income formula
Operating income (EBIT) = GP - OPEX
GP = gross profit (revenue minus cost of goods sold)
OPEX = operating expenses, excluding interest and income tax
Subtracting operating expenses from gross profit leaves the profit from core operations before interest and taxes. Interest and income tax are subtracted further down the income statement to reach net income.
Worked example
A company reports gross profit of 500,000 dollars and operating expenses of 300,000 dollars.
- Gross profit = 500,000
- Operating expenses = 300,000
- Operating income = 500,000 - 300,000 = 200,000
Operating income is 200,000 dollars. These are the calculator's default inputs, so the result above matches the widget exactly.

Operating income calculator: frequently asked questions
What is operating income?
Operating income is the profit a business earns from its core operations, before interest and taxes. It equals gross profit minus operating expenses such as wages, rent, marketing and administration. Because it excludes financing and tax effects, operating income shows how profitable the underlying business is, which is why it is also called earnings before interest and taxes, or EBIT.
How do I calculate operating income?
Subtract operating expenses from gross profit. Gross profit is revenue minus the cost of goods sold; operating expenses are the running costs of the business excluding interest and tax. If gross profit is 500,000 dollars and operating expenses are 300,000 dollars, operating income is 200,000 dollars.
Is operating income the same as EBIT?
They are usually the same and the terms are often used interchangeably. Both measure earnings before interest and taxes. A small difference can arise when a company has non-operating income or expenses, such as gains on asset sales, that are included in EBIT but sit outside operating income. For most businesses the two are identical.
What counts as an operating expense?
Operating expenses are the day-to-day costs of running the business: salaries and wages, rent, utilities, marketing, insurance, depreciation and general administration. They exclude the cost of goods sold, which is already removed in gross profit, and they exclude interest and income tax, which fall below operating income on the income statement.
Why does operating income matter?
It isolates the profitability of the core business from how it is financed and taxed, making it useful for comparing companies and tracking performance over time. Lenders and investors watch operating income because it shows whether operations generate enough profit to cover interest and still leave a return. A rising operating margin signals improving efficiency.
