Operating margin measures how much profit a business earns from its core operations before interest and taxes are counted. It sits between gross margin and net margin, capturing the cost of running the company: salaries, rent, marketing and other operating expenses on top of the cost of goods sold. This calculator takes revenue, cost of goods sold and operating expenses, then reports operating income and the operating margin percentage. Because it strips out financing and tax effects, operating margin is a clean way to compare the efficiency of two businesses or to watch your own trend over quarters. A steady or rising operating margin shows disciplined cost control as you grow, while a shrinking one flags creeping overhead. Enter your three figures and the results appear at once. Every calculation runs locally in your browser.
It subtracts cost of goods and operating expenses from revenue to get operating income, then divides that by revenue.
It excludes interest and taxes, so it isolates profit from core operations before financing and tax effects.
Operating income equals earnings before interest and taxes, so operating margin and EBIT margin measure the same thing.
