Costco Wholesale Corporation reported strong sales growth for July 2025. During the four-week retail period ending August 3, the company achieved net sales of $20.89 billion, representing an 8.5% increase compared to $19.26 billion in July 2024.
Comparable-store sales rose by 6.4%, while e-commerce sales saw a significant surge of 15.1%, surpassing broader retail trends. Year-to-date performance (for the first 48 weeks of the year) also remained robust, with net sales up 8.1%, totaling $248.35 billion.
Regionally, comparable sales increased by 5.5% in the U.S., 7.6% in Canada, and 9.5% in other international markets. When adjusted for gasoline price fluctuations and exchange-rate effects, comparable sales growth was even stronger—total company sales were up 7.0%, and U.S. sales were up 6.5%.
As of early August, Costco operated 910 warehouses worldwide, including 626 in the U.S. and Puerto Rico. The company also maintained e-commerce platforms in eight countries.
Costco’s strong July performance may have been partially driven by consumer behavior ahead of looming tariff increases. A new round of U.S. tariffs on certain imported goods from China is set to take effect on August 1, prompting many shoppers and businesses to accelerate purchases in July to avoid potential price hikes. This preemptive buying could have temporarily boosted sales across key categories, including electronics, household items, and seasonal merchandise.
Retail analysts have pointed to similar patterns in previous tariff cycles, where consumers and distributors front-load purchases to stay ahead of rising costs. While it remains unclear how significantly these tariffs will impact Costco’s pricing or supply chain in the long term, the timing suggests that July’s elevated sales figures may reflect not just organic demand, but also strategic stocking by both consumers and commercial buyers ahead of the August trade policy changes.
