Walmart vs Costco in Fiscal Schedules: Walmart’s FY2026 financial results are compared against Costco’s FY2025 results due to differences in their fiscal year reporting.

Walmart operates on a fiscal calendar that ends on January 31, meaning its FY2026 includes February 2025 to January 2026. In contrast, Costco follows a fiscal year ending in August, making its FY2025 cover September 2024 to August 2025.

Since Costco’s FY2026 results are not yet available at the time of Walmart’s latest fiscal report, analysts and industry comparisons often use Costco’s FY2025 as the closest match when evaluating the two retailers’ financial performance.

This approach ensures that the most recent annual results for both companies are used while accounting for their differing fiscal schedules.

Insight & Summary of Walmart vs Costco in Revenue Per Store

The following analysis consolidates the trends observed across Walmart vs Costco’s revenue per store by segment for the 2016–2026 period.

• The revenue per store comparison between Walmart and Costco is one of the most striking productivity differentials in large-format retail. At the consolidated level, Costco generated $295.3M in revenue per store in 2025 versus Walmart’s $64.5M in 2026 — a 4.6x gap that has remained remarkably persistent throughout the entire period and has, if anything, widened in absolute dollar terms.

• In 2016, the consolidated differential was approximately $121M per store; by 2025, it had expanded to over $230M. Both companies have grown their per-store revenue consistently, but Costco’s trajectory has been steeper — compounding from $162.3M to $295.3M, an 82% increase over nine years, compared to Walmart’s growth from $41.5M to $64.5M, a 55% increase over ten years. The divergence reflects the fundamental differences in store format, average transaction size, and member-driven traffic density that define the warehouse club model relative to conventional big-box retail.

• Within the U.S. market, the productivity gap is equally pronounced but has shown subtle signs of narrowing in percentage terms. Costco U.S. revenue per store grew from $172.8M in 2016 to $318.0M in 2025 — nearly doubling — while the combined Walmart U.S. and Sam’s Club blended U.S. figure grew from $68.5M to $110.5M over the same period. Sam’s Club, as the warehouse club format within Walmart’s portfolio, is the more relevant domestic comparator to Costco — generating $154.8M per store in 2026 versus Costco’s estimated equivalent, representing a more compressed but still significant gap of approximately 2x.

• The trajectory of Sam’s Club’s per-store revenue — growing from $86.8M in 2016 to $154.8M in 2026, an 78% increase — is the most compelling domestic productivity story within Walmart’s portfolio, and the rate of improvement is narrowing the absolute gap with Costco U.S. more meaningfully than any other Walmart segment. Walmart U.S.’s per-store revenue, while growing steadily from $65.2M to $104.7M, operates in a structurally different productivity tier given its broader format mix and smaller average store footprint relative to Costco’s standardized warehouse.

• The international comparison presents a notable convergence dynamic that is largely obscured by Walmart International’s dramatically different store composition. Walmart International’s revenue per store has grown modestly from $18.2M to $22.7M — constrained by the large proportion of smaller-format retail and wholesale stores in its portfolio, particularly in markets like Mexico, Central America, and China, where average store sizes are a fraction of the warehouse format.

• Costco International’s revenue per store, by contrast, grew from $150.2M in 2016 to $263.8M in 2025 — reflecting the consistent application of the full-size warehouse format across all international markets and the maturing productivity of its Canadian, Japanese, Korean, and Australian operations. The international revenue per store differential of approximately 11.6x in 2025 is the widest of any comparison in the dataset, and is primarily a function of format architecture rather than operational performance — a reminder that store count comparisons between the two companies must always be contextualized by the profound differences in format size, revenue model, and customer economics that define each business.
