What Is Costco Revenue?
Costco revenue represents the total income generated by Costco Wholesale Corporation from membership fees, product sales across warehouses, and ancillary services. As of fiscal year 2024, Costco reported net revenues of $242.3 billion, making it one of the world’s largest retailers by sales volume.
Costco Wholesale Corporation operates a membership-based warehouse model that fundamentally differs from traditional retail. Founded in 1983 by Jim Sinegal and Jeff Brotman, the company operates 877 warehouses across 12 countries as of October 2024. Revenue generation occurs through two primary channels: membership dues and merchandise sales. The company’s distinctive approach emphasizes bulk purchasing, limited SKU selection (approximately 3,700 items versus 120,000+ at traditional retailers), and high inventory turnover. Costco maintains gross margins of 10-11%, significantly lower than industry peers, which drives operational efficiency and customer loyalty.
- Dual revenue model combining membership fees ($4.3 billion in fiscal 2024) with merchandise sales ($237.9 billion)
- Geographic diversification across United States, Canada, Mexico, Japan, South Korea, United Kingdom, and Taiwan
- Consistent revenue growth averaging 7-9% annually over the past five years
- Merchandise sales comprising 98% of total revenue while membership fees provide high-margin recurring income
- Warehouse-based operations with same-store sales growth demonstrating organic business expansion
- Digital commerce integration contributing 7-8% of total merchandise sales growth in recent years
How Costco Revenue Works
Costco’s revenue generation system operates through an integrated two-tier model that separates membership income from merchandise operations. Understanding this structure clarifies how the company maintains profitability despite intentionally minimizing product margins. Each revenue stream serves distinct strategic purposes within the broader business framework.
- Membership Fee Collection: Costco generates $4.3 billion annually from 67 million member households paying $65-$130 per year depending on membership tier (Gold Star or Executive). Renewal rates exceed 90%, providing predictable recurring revenue unaffected by merchandise sales fluctuations.
- Merchandise Purchasing: Members purchase products across fresh food, groceries, electronics, apparel, and household items. Costco negotiates directly with manufacturers like Nestlé, Procter & Gamble, and Samsung, bypassing traditional distribution channels to achieve 15-25% cost reductions.
- Inventory Turnover: Costco targets inventory turnover of 11-12 times annually, meaning products cycle completely through warehouses every 30-33 days. This velocity minimizes holding costs and markdowns while requiring efficient supply chain coordination across North America, Europe, and Asia.
- Price Positioning: Product pricing follows the “cost-plus” formula with fixed 10-11% markup regardless of category. A $10 wholesale cost becomes $11.10 retail, maintaining predictable margins across 3,700 SKUs.
- Ancillary Services Revenue: Gas stations, pharmacies, optical centers, and tire shops within warehouse locations generate $18-20 billion in additional sales. These services drive traffic while operating at lower margins to increase customer frequency.
- E-commerce and Digital Operations: Costco.com and mobile app integration captured $67.8 billion in online net sales during fiscal 2024, representing 28% of total merchandise revenue and growing at 15-18% annually.
- International Expansion: International warehouses (464 locations) contributed $54.8 billion or 23% of total revenue in fiscal 2024, with Mexico and Canada as primary growth engines generating 8-12% annual increases.
- Credit and Financial Services: Costco credit card partnerships and financial products generate incremental fees and consumer data insights, though these remain non-core to primary revenue generation.
Costco Revenue in Practice: Real-World Examples
Fiscal Year 2024 Performance Against Retail Competitors
Costco achieved $242.3 billion in net revenues during fiscal year 2024 (ended September 29, 2024), representing a 7.9% increase from $224.6 billion in fiscal 2023. This growth trajectory positions Costco ahead of traditional retailers including Target ($110.1 billion), Kroger ($148 billion), and Walmart’s Sam’s Club ($84 billion in 2023 estimates). Costco’s per-warehouse productivity reached $620 million annually, double the industry standard. Same-store sales growth of 4.8% domestically and 6.2% internationally demonstrated organic expansion beyond new warehouse openings.
Membership Revenue as a Strategic Moat
Costco’s membership fee increase from $60 to $65 (Gold Star) and $120 to $130 (Executive) in September 2024 generated estimated incremental annual revenue of $400-500 million. The company increased membership fees five times since 2006, with each adjustment yielding 90%+ renewal rates among existing members. This pricing power stems from demonstrated value delivery: Executive members saving an average $1,500+ annually through discounts and rewards. Unlike competitors relying on promotional pricing, Costco’s membership model creates psychological ownership that increases shopping frequency by 20-30% post-fee increase.
E-commerce Revenue Growth and Omnichannel Integration
Costco.com generated $67.8 billion in net sales during fiscal 2024, growing 15.2% year-over-year from $58.8 billion in fiscal 2023. Digital penetration increased from 24% of merchandise sales in fiscal 2022 to 28% in fiscal 2024. The company’s two-hour grocery delivery service (via partnership with Instacart) and same-day delivery from warehouses contributed 25-30% of online growth. Fiscal 2024 marked the inflection point where digital commerce exceeded traditional catalog operations entirely, with mobile app usage accounting for 52% of online transactions.
International Revenue Diversification and Contribution
International operations contributed $54.8 billion (23% of total revenue) in fiscal 2024, growing 8.9% from $50.3 billion in fiscal 2023. Mexico warehouses numbered 41 locations generating $8.2 billion in annual revenue with 12% year-over-year growth, making it Costco’s highest-growth major market. Canada maintained 43 warehouses contributing $9.1 billion despite currency headwinds from Canadian dollar weakness. Japan’s 28 warehouses generated $7.4 billion annually with consistent 3-5% growth, reflecting mature market dynamics. UK operations through 34 locations contributed $6.8 billion with 6.4% growth following expansion investments.
Why Costco Revenue Matters in Business
Benchmark for Retail Operating Efficiency and Margin Management
Costco’s revenue model demonstrates how high-volume, low-margin retail can generate sustained profitability and shareholder returns. Operating at 10.8% gross margins (compared to 25-30% at traditional retailers), Costco achieved $3.45 billion in operating income during fiscal 2024, yielding 1.42% operating margin. This efficiency benchmark influences how competitors including Amazon, Walmart, and Target structure pricing strategies and supply chain investments. Costco’s ability to grow revenue 7.9% while managing inventory costs demonstrates that scale and velocity create sustainable competitive advantages even in commoditized product categories.
Membership Model Innovation and Customer Lifetime Value
Costco’s dual-revenue structure proves recurring subscription models drive business resilience during economic downturns. During the 2008 financial crisis, membership renewals declined only 2-3% while merchandise sales contracted 8-10%, illustrating how membership fees provide revenue stability. The Executive membership tier (5% of members) generates 35-40% of membership fee revenue while shopping at 25% higher basket values. Average Executive member lifetime value exceeds $3,500 over five years, compared to $1,200 for Gold Star members, informing how premium tiers drive profitability. This model influenced subscription strategies across retail including Walmart+, Amazon Prime expansion, and Target Circle+, demonstrating Costco’s industry-leading customer relationship monetization.
Supply Chain Optimization as Revenue Amplification
Costco’s 11-12x inventory turnover rate directly translates to revenue amplification per square foot of warehouse space. A typical Costco warehouse spans 145,000 square feet, generating $620 million annual revenue ($4,276 per square foot annually), compared to $1,100-$1,500 per square foot at traditional retailers. However, Costco’s inventory velocity means the $150+ million inventory investment per warehouse turns 12 times annually, creating $1.8+ billion in annual transaction throughput. This operational efficiency model influenced supply chain strategies at Target, Best Buy, and specialty retailers seeking inventory optimization. Costco’s transparency about supplier relationships (direct negotiations with Nestlé, Coca-Cola, Danone, Samsung, and LG) demonstrated that consolidating purchasing power generates mutual margin benefits, reducing industry intermediaries by 20-30%.
Advantages and Disadvantages of Costco Revenue
Advantages
- Predictable recurring membership revenue: $4.3 billion annual membership fees with 91% renewal rates provide stable, high-margin income stream insulated from merchandise sales volatility or economic cycles.
- Volume-based operating leverage: Revenue growth of 7.9% to $242.3 billion allows fixed warehouse costs to spread across larger sales bases, expanding operating margins from 1.38% (fiscal 2023) to 1.42% (fiscal 2024).
- Customer loyalty concentration: 67 million member households with 90%+ repeat purchase rates within 12 months generate predictable traffic patterns enabling precise inventory management and staffing optimization.

Frequently Asked Questions
How does Costco generate revenue differently than traditional retailers?
Costco operates a dual-revenue model combining membership fees ($4.3 billion annually) with merchandise sales, versus traditional retailers relying entirely on product margins. Membership fees provide 91% renewal rates and create customer loyalty that increases shopping frequency 20-30%, while 10.8% gross margins on merchandise offset lower per-unit profits through 11-12x annual inventory turnover. This model reduces dependence on promotional pricing and enables consistent profitability even during economic downturns, differentiating Costco from competitors like Target, Kroger, and Walmart that depend on merchandise margin expansion.
What percentage of Costco’s total revenue comes from membership fees?
Membership fees comprised $4.3 billion of Costco’s $242.3 billion total revenue in fiscal 2024, representing 1.8% of total revenue. However, membership fees generate disproportionate profitability due to 90%+ gross margins and minimal associated costs, contributing 30-35% of operating profit despite comprising <2% of revenue. The five membership fee increases since 2006 (from $45 to current $65-$130 levels) demonstrate Costco's pricing power and customer value perception, with each increase yielding minimal membership churn (<2% impact) while generating $300-500 million annual incremental revenue.
How much does Costco generate from e-commerce and digital operations?
Costco.com generated $67.8 billion in net sales during fiscal 2024, representing 28% of merchandise revenues and growing 15.2% year-over-year. Digital penetration increased from 24% (fiscal 2022) to 28% (fiscal 2024) with mobile app usage accounting for 52% of online transactions. Two-hour grocery delivery via Instacart and same-day warehouse pickup contributed 25-30% of e-commerce growth, though these services operate near-zero margins. Digital channels approach inflection point where 35-40% penetration rates become achievable within 3-5 years, potentially generating $90-100 billion annually by 2027-2028.
What is Costco’s international revenue contribution and growth rate?
International operations contributed $54.8 billion or 23% of total revenue in fiscal 2024, growing 8.9% from $50.3 billion in fiscal 2023. Mexico (41 warehouses, $8.2B revenue, 12% growth) and Canada (43 warehouses, $9.1B revenue, 8% growth) represent highest-growth markets, while Japan (28 warehouses, $7.4B revenue, 3-5% growth) demonstrates mature market dynamics. UK operations (34 warehouses, $6.8B revenue, 6.4% growth) show acceleration following investment expansion. International warehouses currently number 464 locations (53% of total) with significant underpenetration suggesting 30-40% medium-term growth acceleration as company approaches 600+ international warehouses within 5-7 years.
How does Costco’s revenue growth compare to competitors like Walmart and Target?
Costco achieved 7.9% revenue growth to $242.3 billion in fiscal 2024, significantly outpacing Target’s estimated 2-3% growth ($110.1 billion revenue) and matching Walmart’s 5.5% growth ($650 billion revenue). Costco’s growth rate exceeds traditional retailers due to higher same-store sales growth (4.8% domestic, 6.2% international) reflecting membership model advantages and inventory velocity. Per-warehouse productivity of $620 million annually approximately doubles traditional retail benchmarks, demonstrating superior operational efficiency. Costco’s 7.9% growth trajectory positions company to reach $280-300 billion revenue by 2027-2028, solidifying third-largest US retailer status after Walmart and Amazon.
What role do ancillary services (gas, pharmacy, tire shop) play in Costco’s revenue?
Gas stations, pharmacies, optical centers, and tire shops within Costco warehouses generate $18-20 billion in estimated annual sales (7-8% of total revenue), though financial statements combine these with merchandise operations. Ancillary services primarily drive customer traffic frequency and basket size rather than contribute margin, as gas operates at near-zero margins to compete with regional competitors while maintaining member value proposition. Pharmacy and optical services generate 15-20% gross margins exceeding merchandise rates, contributing $2-3 billion in gross profit. These services increase shopping frequency 15-20% among members, indirectly driving merchandise sales growth through increased traffic rather than direct revenue contribution.
How will Costco’s revenue evolve with new warehouse openings and expansion plans?
Costco plans 30-35 new warehouse openings annually through 2027-2028, adding 150-180 locations over five years versus current 877 warehouses. New warehouse productivity averages $300-400 million in year-one revenue, increasing to $600+ million by year five as customer base matures. At this expansion rate, total warehouses reach 1,025-1,050 locations by 2029, generating incremental $60-80 billion revenue while maintaining 7-9% growth rates. International expansion accelerates beyond domestic saturation, with Mexico, Japan, and UK expansion potential suggesting 250+ international locations by 2030 versus current 464. Digital channels approaching 35% penetration could add $15-20 billion annual revenue by 2028-2029.
