How it works
Profit is what is left after costs. Margin is profit as a share of revenue, so it tells you how much of each sale you keep. Markup is profit as a share of cost, so it tells you how much you added on top of what you paid.
They are easy to mix up. A 50% markup is only a 33.3% margin, because the profit is measured against a different base.
Example. Buy at 60, sell at 100, 10 units. Revenue is 1,000 and total cost is 600, so profit is 400. Margin is 40% and markup is 66.67%.
Frequently asked questions
What is the difference between margin and markup?
Margin divides profit by the selling price. Markup divides profit by the cost. The same sale always has a higher markup than margin.
Why does the margin show "Not defined"?
Margin needs revenue above zero and markup needs a cost above zero. Enter a selling price to see the margin.
Does it include tax or delivery?
No. Add delivery, fees and other costs into the cost price to get a true profit figure.
