There are several measurements of profit, including gross profit, operating profit and net profit. Gross profit is sales less the cost of goods sold. Cost of goods sold includes materials, labor and overhead. Operating profit is gross profit less sales expense, general expense and administrative expense. Net profit is operating profit less interest, taxes and other expense. Profit measurements are sometimes referred to as margins and are expressed as a percentage by dividing profit dollars by sales.
On the other hand, a company's net income or profit is determined by subtracting its expenses from its revenues. Thus, revenues are the opposite of expenses, and income equals revenues minus expenses. For example a store may sell $300 worth of merchandise, for which it originally paid $200. In that example the company's revenue is $300, its expense is $200, and its net income or profit is $100. Other expenses that are typically deducted from sales or revenues include salaries, rent, utilities, depreciation, and interest expense. When looking at a company's income statement, it is easy to distinguish between revenues, which appear at the top of the statement, and net income, which appears at the bottom.
