Gross Margin
The share of revenue left after the direct cost of delivering your product or service (cost of goods sold). Software has high gross margins; hardware and delivery-heavy businesses much lower.
Gross margin = (revenue - COGS) / revenue
Why it matters
Gross margin sets the ceiling on how profitable a business can ever be and how much it can spend to acquire customers. It is the first number investors check to judge the quality of a business model.
For example
A SaaS company keeps 85 rupees of every 100 in revenue after hosting and support costs, an 85 percent gross margin; a food-delivery startup might keep only 25.
