To help readers understand the content better, the following terms and glossaries have been provided.

Net Sales: Costco’s net sales refer to the total revenue generated from the sale of goods and services, excluding any returns, allowances, and discounts. This figure represents the company’s core business performance and is a key indicator of its financial health and growth.

These fees help the company maintain a loyal customer base and provide a steady stream of revenue. There are typically two types of memberships:

• Gold Star Membership: This is the standard membership available to individual consumers. It provides access to all Costco locations worldwide and offers various member benefits. The fee for this membership is usually around $60 per year.
• Executive Membership: This membership offers additional benefits, including an annual 2% reward on qualified purchases, which can offset the membership fee. Executive members also receive exclusive discounts and access to special services. The fee for this membership is typically around $120 per year.

These membership fees are a significant part of Costco’s business model, contributing to its overall profitability and helping to keep product prices low for members.

How does Costco make money?

Costco’s business model is quite robust, allowing it to generate revenue from several key channels:

• Membership Fees: An essential part of Costco’s revenue comes from annual membership fees. Members pay to access Costco’s warehouses and benefit from discounted prices. This not only generates a steady income but also fosters customer loyalty.
• Ancillary Services: Costco offers additional services such as gas stations, pharmacies, optical centers, and food courts. These services add convenience for members and contribute extra revenue.


• E-commerce: Besides physical stores, Costco’s online sales are growing. The e-commerce platform allows customers to shop conveniently from home, especially in areas without nearby warehouses.
• Private Label Products: Costco’s private label, Kirkland Signature, is a significant contributor to its revenue. These products are known for their quality and competitive prices, encouraging customers to choose them over national brands.
• Bulk Sales and High Turnover: Costco focuses on selling products in bulk, which increases the average transaction size. The high turnover rate ensures fresh inventory and efficient use of warehouse space.

By leveraging these diverse revenue streams, Costco ensures its position as a leading wholesale retailer.

Insight & Summary of Costco’s Net Sales and Membership Fees

The following analysis consolidates the trends observed across Costco’s net sales and membership fees revenue for the 2016–2025 period.

• Costco operates a uniquely highly leveraged financial model where massive retail scale serves primarily to drive high-margin membership volume.

• Net sales represent the overwhelming majority of the topline, driving a three-year average of $252,416 million and consistently accounting for 98.1% of the total revenue mix.

• However, the strategic core of the business lies within its membership fees. While comprising only 1.9% of total revenue—averaging $4,910 million over the latest three periods — these fees drop almost entirely to the bottom line, underpinning the company’s overall profitability.

• Notably, membership fee growth has structurally decoupled from and outperformed net sales growth in recent years. Over the last three fiscal periods, membership fee revenue expanded at an average rate of 8.0%, visibly outpacing the 6.6% average growth in net sales.

• This divergence highlights Costco’s exceptional member retention rates, expanding global footprint, and robust pricing power, effectively insulating the company’s operating margins from the standard volatility and compression typical of traditional retail models.

The table below combines Costco’s net sales revenue and membership fees into a single view for the latest three fiscal years.
