Margin
–
Profit = selling price − cost
Margin = profit ÷ selling price × 100
Markup = profit ÷ cost × 100
You buy a lamp for 60 and sell it for 100. The profit is 40, the margin is 40 ÷ 100 = 40%, and the markup is 40 ÷ 60 = 66.7%.
Selling price = cost ÷ (1 − margin)
For a 40% margin on something that cost 60: 60 ÷ 0.6 = 100. A common mistake is to add 40% to the cost (84), which only gives a 28.6% margin.
Both compare profit with a price, but against different numbers. Margin is profit as a share of the selling price; markup is profit as a share of the cost. Buying at 60 and selling at 100 is a 40% margin but a 66.7% markup.
Margin = markup ÷ (1 + markup). A 50% markup is 0.5 ÷ 1.5 = a 33.3% margin. The other way round, markup = margin ÷ (1 − margin).
No. Margin can't reach 100%, because that would mean the item cost nothing. Markup has no upper limit: selling something that cost 10 for 50 is a 400% markup.
Leave sales tax and VAT out of both numbers. Use the cost you paid without any tax you can reclaim, and the selling price before tax.
