FAQ
Frequently asked questions
What is the difference between margin and markup?
Both use the same profit, but margin divides it by the selling price while markup divides it by the cost. Buying at 60 and selling at 100 is a 40% margin but a 66.67% markup.
How do I calculate profit margin?
Gross margin = (selling price − cost) ÷ selling price × 100. A product that costs 75 and sells for 100 has a 25% margin.
How do I find the selling price for a target margin?
Divide the cost by (1 − margin). For a 40% margin on a cost of 60, the price is 60 ÷ 0.6 = 100. Adding 40% to the cost (84) would only give a 28.6% margin.
How do I convert markup to margin?
Margin = markup ÷ (1 + markup). A 50% markup equals a 33.33% margin, and a 100% markup (doubling the cost) equals a 50% margin.
Can a margin be more than 100%?
No. Margin is a share of the selling price, so it can approach but never reach 100% unless the cost is zero. Markup has no upper limit — a 300% markup is perfectly possible.
Is this gross margin or net margin?
Gross margin — it only compares the selling price with the direct cost you enter. Net margin also subtracts overheads such as rent, salaries and tax, so include those in the cost if you want a net figure.
