Why markup matters to a first-time founder
Markup connects the cost of an item to its selling price. Setting it without understanding all relevant costs can leave too little gross profit to cover overheads. Founders also need to distinguish markup from margin, because confusing the two produces systematically lower prices than intended.
Examples of markup
A retailer buys a lamp for $40 and adds a 50% markup, which is $20. The selling price is $60. The gross profit is still $20, but the gross margin is 33.3% because profit is divided by the $60 selling price, not by the $40 cost.
Common misunderstanding
Markup and gross margin are not interchangeable percentages. Markup measures profit relative to cost; margin measures profit relative to selling price. A 25% markup on $80 gives a $100 price and a 20% margin. Taxes and discounts may also alter what the business actually keeps.
When to use it
Use it when setting or reviewing prices for products with a clear unit cost. Include freight, payment fees and other direct costs where relevant, then test whether the resulting margin covers overheads. For services or software, value-based pricing and customer willingness to pay may matter more than a cost markup.
