Costco Trades at Elevated P/S Ratio of 1.5 and P/E 51
Costco’s valuation is at multi-year highs with P/S at 1.5 (five-year 1.2), P/E at 51 (average 44) and P/B at 14.1 (average 12.4). Its dividend yield of 0.5% is near decade lows, suggesting the stock trades at a premium relative to historical norms.
1. Warehouse Expansion and Site Reuse Drive Long-Term Growth
Costco added 25 new warehouse locations globally in fiscal 2025, bringing its total to 848 club stores across 12 countries. The company has accelerated its ramp-up of new warehouses, achieving breakeven on new sites within nine months on average, compared with a historical 12-month timeline. In mature markets, Costco has repurposed underused real estate—converting excess parking facilities into pickup-only distribution hubs—which reduced capital expenditures by 7% per location last year. Management forecasts opening 20–25 new warehouses annually over the next five years, supporting projected mid-teens percentage growth in membership fee revenue.
2. Membership Base Fuels Recurring Revenue and Resilience
Costco’s paid membership count reached 128.3 million as of November 2025, up 4.6% year over year. Executive memberships now represent 29% of the total base, generating an average annual fee of $120 versus $60 for standard memberships. Membership fee income contributed $5.3 billion in operating profit in fiscal 2025—accounting for nearly 80% of total operating income—and acts as an annuity that allows Costco to maintain its low-margin, high-volume pricing model. In the most recent quarter, membership renewals held at 91.5%, the highest level in five years, underscoring the loyalty and pricing resilience of Costco’s model even when consumer spending is under pressure.
3. Valuation Remains Historically Elevated but Reflects Growth Optionality
Costco trades at a price-to-sales ratio of 1.5, above its five-year average of 1.2, and a price-to-earnings ratio of 51 versus a long-term average of 44. Its price-to-book ratio stands at 14.1 compared to a five-year average of 12.4, while the dividend yield is 0.53%, near a decade low. Despite these premiums, investors may justify the valuation by pointing to Costco’s consistent high-single-digit comparable-store sales growth—8.2% in the fiscal 2026 first quarter—and its proven ability to expand margins through private-label grocery offerings and increased ancillary services. At a market capitalization of $428 billion, the company’s financial strength and predictable recurring revenue stream underpin management’s forecast of 9–11% annualized operating income growth over the next three years.
