Insights

Retail Sales Analyst

Costco reported broad sales growth with strong digital acceleration and modest comparable-store gains.

Costco posted net sales of 26.58 billion for the five weeks ended October 5, 2025, up 8.0% year-over-year, with Total Company comparable sales of 5.7% and a 26.1% increase in the newly defined "digitally-enabled" metric. The company now counts 914 warehouses globally, supporting both warehouse and digitally-initiated fulfillment channels.

The result shows durable in‑store demand plus outsized digital growth, but comparables exclude impacts from gasoline and foreign exchange which change the headline comps to 6.0%. Last year benefited from abnormal activity tied to weather and port strikes, which reduces the baseline for comparison. The press release also contains standard forward‑looking disclaimers limiting actionable conclusions.

Key items to watch over the next quarter: monthly comparable-sales trends into the holiday period, the trajectory of the digitally-enabled metric versus warehouse sales, any commentary on membership growth or renewal behavior, and how gasoline and FX swing reported comps; monitor these through the next monthly release and the upcoming quarterly commentary in Q4 2025.
