Costco Wholesale Corporation reported significant sales growth for July 2025. During the four-week retail period ending August 3, the company achieved net sales of $208.9 billion.
Sales at comparable stores increased by 6.4%, while e-commerce sales saw a massive 15.1% rise, surpassing the wider retail trends. Year-end performance (first 48 weeks of the year) was also strong, with net sales rising 8.1% to a total of $248.355 billion.
Regionally, comparable sales increased by 5.5% in the US, 7.6% in Canada and 9.5% in other international markets. Adjusting for the impact of gasoline price fluctuations and exchange rates, comparable sales growth rates were even stronger.
As of early August, Costco operates 910 warehouses worldwide, including 626 in the US and Puerto Rico. The company also maintains its e-commerce platform in eight countries.
Costco’s strong July performance could have been driven in part by consumer actions ahead of the looming increase in tariffs. The new US round of tariffs on certain imported goods from China is expected to come into effect on August 1, urging many shoppers and businesses to accelerate their purchases in July, avoiding potential price increases. This pre-buy could have temporarily boosted sales across key categories, including electronics, household items and seasonal items.
Retail analysts point to a similar pattern in previous tariff cycles, as consumers and distributors frontload purchases to preempt rising costs. It remains unclear how important these tariffs will affect Costco pricing or supply chains in the long run, but the timing suggests that the rise in sales in July may reflect not only organic demand, but also strategic inventory by both consumers and commercial buyers ahead of the August trade policy change.
