Markup vs Margin for Ecommerce Operators
Markup and margin answer different questions. Confusing them creates pricing mistakes.
What it means
Markup is measured against cost. Margin is measured against revenue. A 50% markup does not mean a 50% margin.
Why it matters
Operators pricing off markup alone often underestimate how quickly fees, fulfillment, and discounts erode the result. Margin is the more useful language for evaluating contribution outcomes.
Simple formula
Markup = (price - cost) / cost.
Margin = (price - cost) / price.
Common mistakes
- Using markup targets in teams that report margin targets.
- Ignoring the effect of percentage-based fees.
- Comparing marketplace and DTC pricing without normalizing cost structure.
- Treating a markup rule as sufficient pricing discipline.
Practical example
If cost is $40 and price is $60, markup is 50% but margin is 33.3%. Once fees and fulfillment are added, true contribution margin is lower still.
