Margin vs Markup: The Difference

Margin

Profit / Price

$50 profit on $100 price = 50% margin

Used for: Financial reporting, pricing strategy

Markup

Profit / Cost

$50 profit on $50 cost = 100% markup

Used for: Setting prices from cost

If Margin is... Markup is...

20%25%
25%33.3%
30%42.9%
40%66.7%
50%100%
60%150%
75%300%

Why This Matters

Common mistake: A 50% markup does not equal 50% margin. If you mark up a $50 product by 50% ($25), you sell it for $75. Your margin is only 33% ($25/$75).

Gross vs Net: Gross margin ignores overhead costs. Net margin is what actually matters—it's your real profit after everything is paid.

Break-even reality: Until you hit break-even units, you're losing money every month regardless of gross margin. Track this number.
