E-commerce continues to be a vital growth pillar, with online sales rising by 11.5% year-over-year in June. The recent partnership with Affirm, launched in May 2025, introduced Buy Now, Pay Later (BNPL) options for online purchases between $500 and $17,500, effectively lowering purchase barriers for higher-value items and boosting average transaction sizes. This strategic alliance aligns Costco with leading retailers embracing flexible payment solutions to enhance customer spending capacity.
Financial Performance Context and Strategic Implications#
Costco’s fiscal year 2024 results further illustrate the company’s financial robustness. Revenue reached $254.45 billion, a 5.02% increase year-over-year, with gross profit climbing to $32.09 billion, improving the gross margin to 12.61%. Operating income rose to $9.29 billion (+14.59%), reflecting enhanced operational efficiency despite challenging cost pressures. Net income increased by 17.09% to $7.37 billion, boosting the net margin to 2.9%.

Regional and Competitive Landscape#
Costco’s international expansion is a critical growth vector. The 10.9% sales increase in other international markets reflects effective penetration into emerging and developed markets alike. Favorable economic conditions, strategic localization, and a strong value proposition have enhanced consumer adoption outside North America.
Domestically, the US market’s 4.7% sales growth is tempered by inflationary pressures and tariff impacts. However, Costco’s sourcing agility—adjusting supply chains and absorbing tariff costs—helps preserve price competitiveness, contrasting with rivals like Walmart, which have signaled price increases. This positions Costco well to maintain market share and customer loyalty.
Costco's membership model remains a pillar of competitive advantage. With 78.4 million global paid members as of Q2 FY25 and renewal rates exceeding 92.7% in North America, the company secures a stable and recurring revenue stream. Executive members, contributing around 73% of sales, continue to demonstrate strong loyalty, underscoring the effectiveness of Costco’s value-driven membership offerings.

| Metric | Value |
|---|---|
| Global Paid Membership | 78.4 million |
| US & Canada Renewal Rate | 92.7% |
| Executive Members Sales Contribution | 73% |
| Membership Fee Income Q3 FY25 | $1.24 billion (+10.4% YoY) |
Affirm Partnership and E-Commerce Innovation#
The Affirm partnership marks a strategic milestone in Costco’s e-commerce evolution. By offering BNPL options with interest rates ranging from 10% to 36% APR over terms of 3 to 36 months, Costco increases affordability for higher-ticket online purchases. This initiative is designed to expand the customer base, reduce purchase hesitations, and enhance average order value.
This approach contrasts with competitors who often emphasize interest-free, shorter-term BNPL solutions. Costco’s broader term and interest spectrum caters to varied consumer financing needs, potentially elevating total online sales beyond the observed 11.5% growth in June.
Given the US BNPL market size of approximately $175 billion as of late 2024, with 38% consumer penetration, Costco’s timely adoption of Affirm’s solution aligns it competitively with Amazon and Shopify, reinforcing its digital sales capabilities.
What Does This Mean for Investors?#
- Robust sales growth driven by international expansion and e-commerce innovation signals sustainable revenue streams.
- Strong financial health with positive net debt and high ROE/ROIC ratios supports ongoing strategic investments and shareholder returns.
- Effective tariff management preserves Costco's pricing advantage amid inflationary pressures.
- Membership loyalty metrics underscore a resilient business model that fosters recurring revenue and customer retention.
- Affirm partnership enhances e-commerce competitiveness, positioning Costco to capitalize on the growing BNPL trend.
Conclusion#
Costco Wholesale Corporation’s recent performance highlights a well-executed strategy balancing global expansion, technological innovation, and operational efficiency. The 5.8% June comparable sales surge, led by international markets and bolstered by e-commerce advancements like the Affirm partnership, illustrates Costco's ability to adapt and thrive amid complex macroeconomic challenges.
Financial metrics confirm the company's robust profitability and capital discipline, with strong margins, cash flow generation, and prudent debt management. The membership model continues to be a cornerstone, delivering stable, high-margin revenue that underpins Costco’s value proposition.
As tariff pressures and economic uncertainties persist, Costco’s agile supply chain and customer-centric innovations position it favorably against competitors. For investors, these developments affirm Costco’s strategic resilience and growth potential in the evolving retail landscape.
