What decision this helps you make: How to recognize and use a membership model where the fee, not the product, is the business.

What this topic is

The Costco model sells goods at rock-bottom markups — barely enough to cover the cost of running the stores — to offer unbeatable prices, and earns the real profit from recurring membership fees. The low prices attract and retain members; the fee is where the money is.

Why it matters

It's a masterclass in separating what attracts customers from what earns profit — and in aligning a company perfectly with its customers. Both Costco and its members want the lowest possible prices on goods, because Costco makes its money on the fee, not the markup. Understanding it reveals how "unprofitable" pricing can be brilliant strategy.

Who should learn it

Anyone designing a pricing or business model — and anyone puzzled by how a retailer thrives while making almost nothing on the products it sells.

What you will understand

  • See how goods can be sold at near-cost by design
  • Understand where the real profit comes from (the fee)
  • Know why this aligns the company with its customers
  • Recognize where the membership model works and where it doesn't

Prerequisites

Common misconception

"A retailer makes its money by marking up what it sells." Not always. Costco marks up goods only ~11–14% — barely covering store costs — and earns most of its profit from membership fees. The products are near-cost bait; the recurring fee is the actual business. What attracts customers and what earns profit can be two completely different things.
