What is POR?
POR (Profit on Return) POR tells you how much profit you make as a percentage of the selling price. Formula: POR = (Profit ÷ Selling Price) × 100 Example: If you sell something for £10 and make £3 profit: POR = (3 ÷ 10) × 100 = 30% Why it matters: It helps you see how strong your margin is based on the retail price, not the cost.
