The formula
selling price = cost ÷ (1 − margin) cost price = selling price × (1 − margin)
The margin is a share of the selling price, so the cost is whatever share of the price remains.
What to watch out for
Include every cost per unit you want the price to recover. Enter the selling price before any sales tax you collect, as that tax is not part of your margin. Tax you cannot reclaim on purchases is part of your cost.
Frequently Asked Questions
How do I work out a selling price from a margin?
Divide the cost by one minus the margin. A cost of 40 at a 40% margin sells for 66.67.
Why not just add 40% to the cost?
That is a markup, not a margin. Adding 40% to 40 gives 56.00, which is a margin of only 28.57%.
How much can I pay if I know the selling price?
Multiply the selling price by one minus the margin. To keep a 40% margin on a selling price of 100, pay no more than 60.00.
