Formulas
- Margin = (price − cost) ÷ price
- Markup = (price − cost) ÷ cost
- Price for a target margin = cost ÷ (1 − margin)
- Break-even units = fixed costs ÷ (price − variable cost)
Example
You buy at 60 SAR and sell at 100 SAR before VAT, with 20,000 SAR of fixed costs a month:
- Profit per item: 40 SAR, a 40% margin and 66.7% markup
- Break-even: 20,000 ÷ 40 = 500 sales a month
Remember to add 15% VAT to prices shown to customers if you’re VAT-registered; see the VAT calculator.
