Margin may refer to:
Gross margin is the difference between revenue and cost of goods sold, or COGS, divided by revenue, expressed as a percentage. Generally, it is calculated as the selling price of an item, less the cost of goods sold (production or acquisition costs, essentially). Gross Margin is often used interchangeably with Gross Profit, but the terms are different. When speaking about a dollar amount, it is technically correct to use the term Gross Profit; when referring to a percentage or ratio, it is correct to use Gross Margin. In other words, Gross Margin is a % value, while Gross Profit is a $ value.
Gross Margin is a type of profit margin, specifically a form of profit divided by net revenue: for example, gross (profit) margin; operating (profit) margin; net (profit) margin; etc.
The purpose of margins is "to determine the value of incremental sales, and to guide pricing and promotion decision."
"Margin on sales represents a key factor behind many of the most fundamental business considerations, including budgets and forecasts. All managers should, and generally do, know their approximate business margins. Managers differ widely, however, in the assumptions they use in calculating margins and in the ways they analyze and communicate these important figures."
In economics, a margin is a set of constraints conceptualised as a border. A marginal change is the change associated with a relaxation or tightening of constraints — either change of the constraints, or a change in response to this change of the constraints.
Margins are sometimes conceptualized as extensive or intensive:
Where did you go my dear?
Is it all the same?
For miles your margin clears
Are they to blame?
I am a vessel here
My thoughts to tame
No one comes close to who you are
You're far away.
The weeks seemed to stretch for years what was gone in a kiss
I know what you're doing here, it's all I’ve known since
But reasons aside my dear, your heart I will miss
No one could ever take me now
No one could replace what I’ve found
In that moment I was fading away
In that moment things were starting to change
In that moment I needed to stay
