The Charts That Explain Costco's 54x Earnings Multiple

Membership fee revenue hit approximately $4.8 billion in fiscal 2025. That number — just 1.7% of total revenue — funds the entire profit engine. Strip out membership fees and Costco's retail operation runs at roughly breakeven. This is deliberate. Management has maintained retail margins at 1.5-2% for decades, passing all cost savings through to members. The result is a flywheel: low prices drive membership growth, which drives fee revenue, which funds the low prices.

Costco's membership renewal rate sits above 92% globally and 93% in the US and Canada. These are software-like retention metrics applied to a physical retail business. The viral gold bar phenomenon — Costco members buying gold bullion in stores — generated enormous social media buzz and drove foot traffic, but it's a symptom of something deeper: members trust Costco as a value arbitrage platform across every product category.

If you value Costco's membership business as a recurring revenue subscription — which is functionally what it is — the numbers look different. $5.1 billion in annual recurring revenue with 92% retention, growing at 8% annually, attached to 130+ million cardholders. A standalone subscription business with those metrics would command 15-20x revenue. That puts the membership alone at $75-100 billion.

The retail operation, valued on an asset basis or a minimal margin retail multiple, adds another $80-120 billion. Together: $155-220 billion. The current market cap is $458 billion. The premium above our range reflects the market pricing in continued membership growth, e-commerce expansion, and international store openings. At 54x earnings, Costco isn't cheap — but the premium is earned.
