Gross Margin Ratio. Gross margin ratio is the ratio of gross profit of a business to its revenue. It is a profitability ratio measuring what proportion of revenue is converted into gross profit (i.e. revenue less cost of goods sold). Gross margin is calculated as follows: Gross profit and revenue figures are obtained from the income statement of a business.
Gross Margin. Gross margin represents the percentage of net sales that the firm takes in as gross profit. It equals gross profit divided by net sales. If you have sold $500,000 worth of product, and the cost of goods sold is $300,000, the gross profit is $200,000. The gross margin is $200,000 divided by $500,000 which equals 40 percent. A business should not focus on gross margin exclusively, since you can increase gross margin but end up with less in gross profits. If your gross profits drop to $170,000 and sales decline to $400,000, gross margin would be higher, at 42.5 percent, yet gross profits would be $30,000 lower. Contribution Margin Contribution margin is a more relevant measure to assess the profitability of additional products sold, and only takes into account variable costs.
