Net Margin, also known as Net Profit Margin, is a financial ratio that measures a company's profitability by comparing its net income to its total revenue. It indicates what percentage of revenue is left as profit after accounting for all expenses. A higher net margin generally indicates better profitability. To calculate net margin, you divide the company's net income by its total revenue. For Cleveland-Cliffs (CLF), the net margin calculation would involve using the company's net income and total revenue.
