Profit margin

Profit margin is the share of each sale a business keeps as profit after costs. Gross margin subtracts only what the product costs; net margin also subtracts rent, wages and every other expense.

What profit margin is

Margin is profit divided by revenue, written as a percentage. A coffee that sells for €3.50 and costs €0.70 in beans, milk and cup leaves €2.80, a gross margin of 80%. Net margin is far lower once rent, staff and energy are paid, and it is the number that says whether the business makes money at all.

How it works for a café, salon or restaurant

  • A café uses margin to pick a reward: a free coffee costs the beans and milk, not the menu price.
  • A salon compares services, because a colour treatment and a quick trim can leave very different margins.
  • A restaurant checks dish margins before a promotion, so the discount lands on dishes that can carry it.

Margins also show which products belong on a loyalty card: reward with the items that keep the most of their price.

What to watch

A discount comes straight out of margin, so 10% off a product with a 20% margin gives away half the profit on it. Price rewards at what they cost you, not at what they sell for, and weigh the margin given away against the extra visits it brings.
