Key takeaway
Margin divides profit by price; markup divides profit by cost. Same dollars, different percentages — mix them up and pricing meetings go sideways.
Learn both so you can translate vendor and retail language.
What it means
If cost=$100 and price=$150, profit=$50. Margin=50/150=33.3%. Markup=50/100=50%.
People casually say “50% margin” when they mean markup — ask which.
When you would use it
Negotiating with suppliers, setting retail prices, reviewing agency decks.
Any time two stakeholders quote percentages.
How to use the tool
Use the matching TCB Tools page and work top to bottom:
- Open both Margin and Markup calculators.
- Enter the same cost and price.
- Compare the two percentages.
- Agree which number your team will speak.
No account is required. Results update as you type.
Side-by-side method + worked example
Margin% = (P−C)/P×100; Markup% = (P−C)/C×100.
$100 cost → $150 price: margin 33.3%, markup 50%.
To hit target margin m, price = cost ÷ (1−m).
How to read the result
Neither number includes all overhead.
Pick one convention per document.
Planning aid.
Common mistakes
- Using the words interchangeably. Define.
- Targeting markup but calculating margin. Match formulas.
- Forgetting tax/VAT contexts. Separate.
- Changing cost basis silently. Document.
