Learn how markup and margin relate, the exact formulas behind this converter, and the edge cases that trip up sellers.

Core Use Case scenario

Retailers, e-commerce sellers, and product managers quote prices using markup (a percentage added to cost) while their financial reports and buyer agreements talk about margin (a percentage of the selling price). This tool converts in both directions so a 40% markup on a $50 product becomes a 28.57% margin — and lets you back into a sale price from either a target markup or a target margin.

markup% = (price − cost) / cost × 100
margin% = (price − cost) / price × 100
price = cost × (1 + markup%)
price = cost / (1 − margin%)

Troubleshooting & Edge-Case Failure Points

  • Margin above 100% is impossible: a price would have to be infinite because margin is always measured against the full sale price.
  • A margin of 100% (price = double the cost) equals a markup of 100%, but a markup of 100% equals only a 50% margin — the two are not interchangeable.
  • Selling below cost produces a negative markup, negative margin, and a negative profit: the tool flags this as a loss.
  • Rounding a sale price to a "nice" number slightly shifts the realized margin, so always recompute after you round.

Detailed Step-by-Step Instructions

  1. Pick the pair of numbers you already know using the radio buttons (Cost + Markup, Cost + Margin, or Cost + Sale Price).
  2. Enter the product cost in dollars.
  3. Enter the second known value: a markup percentage, a desired margin percentage, or a target sale price.
  4. Review all four outputs — sale price, profit per unit, markup %, and margin % — and use the Copy button to save a summary.

How to Use the Markup & Margin Converter

  1. Enter cost and price — see markup AND margin instantly, they are not the same number.
  2. Or work backwards: enter a cost and a target margin to get the price; or cost plus target markup.
  3. Paste a product list if the tool supports batch mode — price a whole catalog at once.

How the Math Works

Markup = (Price − Cost) ÷ Cost    Margin = (Price − Cost) ÷ Price
Price for target margin M: Cost ÷ (1 − M)

Worked example: cost $60, price $100: markup = 40 ÷ 60 = 66.7%, but margin = 40 ÷ 100 = 40%. Same product, two numbers — and conflating them is the most common pricing error in small business. The inverse rules: to earn a 40% margin on a $60 cost, price = 60 ÷ (1 − 0.40) = $100; a "100% markup" ($120 price) yields only a 50% margin. Discounting shows why margin discipline matters: from $100, a 20% sale ($80) cuts your profit from $40 to $20 — half the profit for 80% of the price — so you need 2x volume just to break even on the decision.

Markup & Margin FAQ

What is the difference between markup and margin?

Markup is profit as a percent of cost; margin is profit as a percent of price. 66.7% markup = 40% margin on the same item. Markup always reads bigger - know which one a conversation is using.

How do I price for a 40% margin?

Divide cost by (1 - 0.40): a $60 cost prices at $100. Common mistake: multiplying cost by 1.40, which yields only a 29% margin.

What margin do retailers typically use?

Grocery runs 1-3% net (25-30% gross), apparel 50%+ gross, jewelry 50-60%. Compare against your industry gross margins before panicking or celebrating.

Why do small discounts hurt so much?

Discounts come straight out of profit. On a 40% margin product, a 10% price cut removes 25% of the profit; you need 33% more volume to stay even.
