Sneak Peek Into Costco’s Comparable Sales Performance

For the five weeks ended July 5, 2026, Costco reported an 8.8% year-over-year increase in total comparable sales. Regionally, comparable sales rose 10.6% in the United States, 3.7% in Canada and 4.7% in Other International markets. While this marked a slowdown from total comparable sales growth of 12.5% in May and 11.6% in April, the June performance still reflected healthy underlying demand.

Excluding the effects of gasoline prices and foreign exchange, U.S. comparable sales increased 7.6%, while Canada and Other International markets posted gains of 4.9% and 5.6%, respectively. Overall, total comparable sales, excluding these factors, rose 7% in June, following increases of 8% in May and 7.8% in April.

Digitally enabled comparable sales remained a standout, rising 20.9% in June, or 21.5% after adjusting for fuel and currency impacts. This followed gains of 21.1% in May and 18.8% in April, underscoring sustained momentum in Costco’s online channel.

Costco’s net sales for June increased 10.6% to $29.24 billion from $26.44 billion in the year-ago period. Although growth moderated from May’s 14.5% increase and April’s 13% gain, the retailer’s June performance suggests that its value proposition and digital strength continue to support solid sales momentum.
