Markup vs Margin: The Comparison Tool

Frequently Asked Questions

• What is the difference between markup and margin? +
  Markup is profit divided by cost: (Price − Cost) ÷ Cost. Margin is profit divided by selling price: (Price − Cost) ÷ Price. Both use the exact same profit dollar amount — they just divide it by a different number, which produces two different percentages from the same transaction.
• Why does a 50% markup only equal a 33.3% margin? +
  Because markup divides profit by the smaller number (cost) while margin divides profit by the larger number (selling price). Dividing the same profit by a smaller denominator always produces a bigger percentage — which is why markup percentages are always higher than the equivalent margin percentage.
• Which one should I use for pricing decisions? +
  Margin is generally the better number for profitability planning and comparing against industry benchmarks, since almost all published benchmark data (including this site's) is margin-based. Markup is common in retail and wholesale pricing conversations because it's simpler to apply directly to a known cost.
• How do I convert markup to margin, or margin to markup? +
  Margin from Markup: Markup ÷ (100 + Markup) × 100. Markup from Margin: Margin ÷ (100 − Margin) × 100. This calculator does both conversions instantly — enter either number and get the other.
• What's the most expensive version of this mistake? +
  Pricing an entire product catalog by adding a markup percentage while a business plan, investor deck, or bank loan application reports margin targets. The business ends up structurally less profitable than its own paperwork claims, often by double digits at higher percentage targets.

A Quick Reference You Can Memorize

If you only remember one thing from this page: markup is always a bigger number than margin for the same transaction, and the gap grows as the percentage grows. At low percentages (under 15%) the two are close enough that the mix-up rarely matters. Above 30%, the gap becomes real money. Above 50%, the gap becomes a pricing strategy problem. Whichever number your business uses internally, make sure everyone quoting a percentage — sales, finance, and ownership — is using the same one, and label it explicitly as "markup" or "margin" in every internal document rather than assuming it's understood.
