## Same profit, two percentages

Markup and margin both describe profit, but against different bases:

- **Markup** = profit as a percentage of **cost**.
- **Margin** = profit as a percentage of **selling price**.

A product bought at AED 100 and sold at AED 150 has a **50% markup** but only a **33.3% margin**. Same AED 50 profit — two very different percentages.

## Why the mix-up costs you

Many retailers price using markup but report or plan using margin. If you think a 40% markup gives you a 40% margin, you're overestimating what you keep on every sale. Over a full catalogue, that gap is real money.

## The formulas

- Margin % = (selling price − cost) ÷ selling price × 100
- Markup % = (selling price − cost) ÷ cost × 100
- Selling price for a target margin = cost ÷ (1 − margin)

The free [Profit Margin Calculator](https://www.pyalm.com/free-tools/profit-margin-calculator) does all three. Enter cost and price to see margin and markup, or enter a target margin to find the price you should charge.

## Scale it across your catalogue

One product is easy to price by hand. Managing margins across hundreds of SKUs, suppliers, and price changes is where [Pyalm Books](https://www.pyalm.com/books) earns its keep — keeping cost, pricing, and profit visible across your whole range.
