Margin and markup are not the same
Both start from the same profit. Margin divides it by the price; markup divides it by the cost. Cost 60, price 100: margin 40%, markup 66.67%. A 50% markup is only a 33.33% margin.
The formulas
- Profit = price − cost
- Margin % = profit ÷ price × 100
- Markup % = profit ÷ cost × 100
- Price for a target margin = cost ÷ (1 − margin)
For a service business, count your time as a cost too, at the hourly rate you need; otherwise every margin looks better than it is.
