Costco September net sales rise 13% to $30.02 billion

Costco Wholesale reported net sales of $30.02 billion for its September retail month, up 13.0% from $26.58 billion a year earlier, the company said in an Oct. 7 announcement.

The period covers the five weeks ended Oct. 4, 2026.

Comparable sales

Total company comparable sales rose 11.4%. By region, U.S. comparable sales rose 12.5%, Canada 6.3% and other international 10.8%.

Excluding the effects of gasoline prices and foreign exchange, total comparable sales rose 7.6%. On that basis, the U.S. rose 8.0%, Canada 4.9% and other international 7.7%.

Digital and calendar effects

Digitally enabled sales rose 19.0%, or 19.1% excluding foreign exchange.

Costco said Labor Day fell one week later this year in the U.S. and Canada. That shift lifted September total and comparable sales by a little more than 50 basis points, the company said.

Footprint

Costco operates 939 warehouses, including 647 in the United States and Puerto Rico and 115 in Canada.
