Margin

The difference between the selling price and the cost of a product or service. It shows how much the company retains after covering costs.

What is margin

Margin is the difference between the price at which you sell a product or service and how much it costs to produce or deliver it. Expressed as a percentage, it indicates the share of each euro of revenue that remains after covering costs.

Basic formula:

Margin (%) = (Selling price – Cost) / Selling price × 100

Gross, operating, and net margin

There are different levels of margin, depending on which costs are considered:

Type What it subtracts from revenue What it's for
Gross margin Direct costs only (materials, labor) Understanding the product's basic profitability
Operating margin Direct costs + operating expenses (rent, indirect staff) Understanding how much the business earns net of current expenses
Net margin All costs, including taxes and financial charges The bottom line: what's truly left

Why it matters for an SME

Knowing the margin per product or per client is the first step toward understanding where the money goes and calculating the true cost of a product. Without this data, decisions on pricing, discounts, and investments are based on gut feeling.

Margin is one of the 5 numbers to check every week to keep the business under control.
