What it means
Profit margin is a profitability ratio that shows the percentage of revenue that a company keeps as profit after paying all expenses. It is a key indicator of financial health and operational efficiency. Different margins exist: gross margin, operating margin, and net profit margin. A higher margin means more profit per dollar of sales. Profit margins are used to compare companies within the same industry, to assess pricing strategies, and to evaluate cost control. Understanding profit margins is essential for business owners, investors, and financial analysts to evaluate performance and sustainability.
