Markup vs. Margin

Same two numbers, different denominator, different answer.

Markup = profit ÷ cost. Margin = profit ÷ price. They are not the same.

Markup and margin use the same profit number but different denominators — cost for markup, selling price for margin. This makes a 50% markup only a 33% margin, and most pricing errors come from confusing them.

Same two numbers, different denominator, different answer.
Limit to remember
Treat this as a practical aid for the task, not a replacement for professional judgment.

Key points

  • Markup = (price − cost) ÷ cost. Denominator is COST.
  • Margin = (price − cost) ÷ price. Denominator is PRICE.
  • For a product that costs £10 and sells for £15: markup = 50%, margin = 33.3%.
  • Markup > margin always (for positive profits).
  • Retail uses margin; wholesale and trade often use markup. Know which a conversation is using.

Examples

  • Cost £10, price £15
    Markup: (15 − 10) ÷ 10 = 50%. Margin: (15 − 10) ÷ 15 = 33.3%.
  • Cost £40, price £100
    Markup: 60 ÷ 40 = 150%. Margin: 60 ÷ 100 = 60%.
  • Target 40% margin
    Price = cost ÷ (1 − 0.40) = cost ÷ 0.60. A £30 item needs £50 retail.

Frequently asked questions

Why does the same product have a 50% markup but only 33% margin? Troubleshooting

Markup uses cost (£10) as denominator: £5 profit ÷ £10 cost = 50%. Margin uses price (£15): £5 ÷ £15 = 33.3%. Same profit, different comparison basis.

Which one should I quote to a customer?

Neither — quote the price. Markup and margin are internal business metrics. Customers only care about what they pay.

How should I use this guide with a Kefiw tool? How-to

Use the guide as the plan and the linked Kefiw tool as the check. Read the steps first, try the move manually, then use the tool to compare outputs, catch edge cases, and decide whether the result actually fits your task.

What mistake do tool guides help avoid? Troubleshooting

Tool guides help avoid using a utility mechanically without understanding what you are trying to accomplish. Most word, writing, and text utilities are fast, but speed can hide context mistakes. Know whether you are solving a puzzle, cleaning copy, drafting a line, or checking a rule.

Can a tool guide help me learn the skill? How-to

A tool guide can help you learn if you pause before accepting the output and ask why it worked. Compare your first guess with the tool result, look for the rule or pattern, and repeat that review. Passive copying solves one task; active review builds the skill.
