§ 02 / ABOUT

How markup sets price.

Markup is the percentage you add on top of cost to get the selling price. price = cost × (1 + markup/100). A $10 item marked up 50% sells for $15 — $5 of that is profit, $10 is cost recovery.

// TYPICAL MARKUPS

  • Grocery — 10–15% (thin margins, high turnover).
  • Apparel retail — 100% (keystone pricing, doubled from wholesale).
  • Restaurants — 300%+ on drinks, 200–300% on food plates.
  • Jewelry — 100–300% depending on material and brand.

// DON'T CONFUSE IT WITH MARGIN

A 100% markup is a 50% margin. A 50% markup is a 33% margin. Pricing tools and P&L dashboards often use different vocabularies — confirm which number you're quoting before you quote it. For the inverse side, see Margin.

§ 02 / FAQ

Questions. Answered.

How do I calculate markup?+
Multiply the cost by the markup percentage, then add it back to the cost. So $50 with a 60% markup is $50 × (1 + 0.60) = $80. Type cost on the left and markup % on the right — the selling price appears instantly.
What’s the difference between markup and margin?+
Markup is profit as a percentage of the cost. Margin is profit as a percentage of the selling price. A $50 item sold for $80 has a 60% markup but a 37.5% margin — same profit, different denominators. Markup drives pricing; margin measures profitability.
What’s a typical markup for retail?+
Keystone pricing (100% markup, doubling cost) is the classic retail rule of thumb. Apparel runs 100–350%, jewelry 100–200%, grocery 10–25%, restaurants 60–300% on food. Check industry benchmarks rather than a universal number.
Can I enter a markup over 100%?+
Yes. Many categories use triple or quadruple markup (200%, 300%). The calculator handles any positive percentage and also accepts negative markups if you’re modeling a discount on cost.
Does the URL update so I can share or bookmark a calculation?+
Yes. As you type, the URL updates to /markup/50-by-60 (cost by markup%). Copy the URL bar to share, or use the SHARE button in the answer bar for one-click options.
Are my calculations stored anywhere?+
No. Math happens entirely in your browser. The URL syncs locally and we keep no record of what you compute.
