About this tool
To earn a given margin you cannot simply add that percentage to the cost: divide the cost by (1 − margin) instead.
Frequently asked questions
Why is cost + 40% not a 40% margin?
Because margin is measured on the selling price. 30 + 40% = 42, and 12 ÷ 42 is only a 28.6% margin. The right price for 40% is 30 ÷ 0.6 = 50.
