简单来说，margin是百分比，profit是绝对值。 比如：收入是100， 成本是80，则毛利（gross profit）是20，扣除其他税费之后净利润（net profit）假设是10，那么毛利率（Gross profit margin）=20/100=20%，净利率（Net profit margin）=10/100=10%。 以下是英文版详细解释： Margin is used to compare A relative to B, where A is part of B. Margin is usually stated as a percentage. Followings are two examples of margins: 1. Gross profit margin = Gross profit / revenue; 2. Net profit margin = Earning after tax / revenue; In accounting, a simple expression of a profit and loss statement is as follows: Revenue 1,000 Cost of good sold -900 Gross PROFIT 100 Operating expenses -10 other expenses -2 tax -3 net PROFIT after tax 85 then, Gross profit MARGIN = 100/1000 = 10%. Net profit MARGIN = 85/1000 = 8.5% -------------- PROFIT is a certain amount of benefit obtained from operations of a company or from trading activities. Different from a margin, profit is stated in a full monetary value. In the above example, the gross profit MARGIN is 10% but the Gross PROFIT is 100; and net profit MARGIN is 8.5% but the Net PROFIT after tax is 85.
