The Power of Membership-Driven Retail

Costco’s unique membership model — requiring annual fees ($60/year for basic, $120/year for executive) — ensures high customer loyalty and predictable revenue.
In 2025, Costco boasts:

  • Over 70 million U.S. memberships,
  • Renewal rate of 92%, among the highest in retail.

Costco’s value proposition is unbeatable: high-quality goods, bulk savings, and exclusive brands like Kirkland Signature.

Omni-Category Dominance

Costco thrives across multiple product categories:

  • Groceries
  • Electronics
  • Apparel
  • Pharmacy and Optical
  • Tires and Automotive Services
  • Travel packages and Insurance

This diversification reduces vulnerability to economic cycles and strengthens brand stickiness.
