Unit
"Each business has its own notion of a 'unit', ranging from a ton of margarine to 64 ounces of glue to a bucket of gypsum. Many industries work with multiple units and calculate margin accordingly... Marketers must be prepared to switch between different perspectives with little effort because decisions can be rounded to any of these perspectives."[1].
Investopedia defines gross margin as:.
Gross margin (%) = (Revenue - Cost of goods sold) / Revenue[2].
It can be expressed in absolute terms:
Gross margin = net sales - cost of goods sold + annual return on sales.
or as the relationship between gross profit and revenue, usually in the form of a percentage:.
Cost of sales (also known as cost of goods sold or COGS) includes variable costs and fixed costs directly linked to the sale, such as material costs, labor, supplier profits, shipping costs (cost of getting the product to the point of sale, as opposed to shipping costs which are not included in COGS), etc. It does not include indirect fixed costs such as office expenses, rent, administrative costs, etc.
Higher gross margins for a manufacturer reflect greater efficiency in converting raw materials into revenue. For a retailer it will be their wholesale price margin. Larger gross margins are generally considered ideal for most companies, with the exception of discount retailers who instead rely on operational efficiency and strategic financing to remain competitive at lower margins.
Two related metrics are margin unit and margin percentage:.
"Percentage margins can also be calculated using total sales revenue and total costs. When working with percentage or unit margins, marketers can perform a simple check by verifying that the individual parts add up to the total."[1].
"When considering multiple products with different revenues and costs, we can calculate the overall margin (%) on either basis: Total revenue and total costs for all products, or the dollar-weighted average of the percentage margins of the different products."[1].
Retailers can measure their profits using two basic methods, markup and margin, which provide a description of gross profit. Profit margin expresses profit as a percentage of the product's cost to the retailer. Margin expresses profit as a percentage of the retailer's selling price of the product. These two methods give different percentages as results, but both percentages are valid descriptions of the retailer's profits. It is important to specify which method you are using when referring to a retailer's profits as a percentage.
Some retailers use margins because they can easily calculate profits from a sales total. If your margin is 30%, then 30% of your total sales is profit. If your profit margin is 30%, the percentage of your daily sales that are profits will not be the same percentage.
Some retailers use markups because it is easier to calculate a selling price from a cost using markups. If your profit margin is 40%, then your selling price will be 40% above the cost of the item. If your margin is 40%, your selling price will not be equal to 40% above cost (in fact, it will be approximately 67% above the cost of the item).
The equation to calculate the monetary value of gross margin is: gross margin = sales - cost of goods sold.
A simple way to maintain markup and gross margin factors is to remember that:.
Gross margin (as a percentage of revenue).
Most people find gross margin easier to work with because it directly tells you how much of the sales revenue, or price, is profit. In reference to the two previous examples:
The $200 price that includes a 100% profit margin represents a 50% gross margin. Gross margin is just the percentage of the sales price that is profit. In this case, 50% of the price is profit, or $100.
In the more complex $339 sales price example, a 66% profit margin represents approximately a 40% gross margin. This means that 40% of the $339 is profit. Again, gross margin is just the direct percentage of profit on the sales price.
In accounting, gross margin refers to sales minus the cost of goods sold. It is not necessarily a profit, since other expenses such as sales, administration and finance must be deducted. And it means that companies are reducing their cost of production or passing their cost on to customers. The higher the ratio, like all other things, the better for the retailer.

Using gross margin to calculate selling price.
Given the cost of an item, one can calculate the selling price required to achieve a specific gross margin. For example, if your product costs $100 and the gross margin required is 40%, then.
Selling price = $100 / (1 - 40%) = $100 / 0.6 = $166.67.

In some industries, such as clothing, for example, profit margins are expected to be close to 40%, as goods must be purchased from suppliers at a certain rate before being resold. In other industries, such as software product development, the gross profit margin can be greater than 80% in many cases.[3].
