In the business world, profitability is the ultimate indicator of success. It's the bottom line that determines how well a company is performing, calculated by subtracting all expenses, taxes, and costs from total revenue to arrive at net income. While revenue alone can impress, it’s the profit margin and return on assets (RoA) that truly reflect financial health. As economist Milton Friedman once said, “The social responsibility of business is to increase its profits.”
