How it works

Profit = selling price − cost. Margin = profit ÷ selling price × 100. Markup = profit ÷ cost × 100. An item bought for 80 and sold for 100 has a profit of 20, a margin of 20% and a markup of 25%.

Questions

What is the difference between margin and markup?

Margin compares profit with the selling price. Markup compares profit with the cost. The same sale always has a higher markup than margin.

Should cost include shipping and other expenses?

Include every cost directly tied to the item, such as purchase price and inward freight, to see a realistic margin.

Can the margin be negative?

Yes. A negative figure means you sell below cost.
