Costco Just Had a Nearly $300 Billion Year- and Online Sales are Surging

Costco just wrapped up another massive year.

The warehouse club reported $297.3 billion in net sales for its 2026 fiscal year, bringing it close to the $300 billion mark. Costco’s fiscal year does not follow the regular January-to-December calendar. Its 2026 fiscal year ended on August 30, 2026.

That $297.3 billion total was up 10.2% from $269.9 billion the year before.

And while Costco is still known for giant warehouses and overflowing shopping carts, one of the fastest growing parts of its business is happening away from the checkout line.

Costco’s digitally enabled comparable sales jumped 20.9% for the full fiscal year.

That growth was significantly faster than Costco’s overall comparable sales, which increased 8.4% during the same period.

Costco Sales Are Still Growing Fast

For Costco’s fiscal year ending August 30, 2026, the company reported strong growth across its markets.

Comparable sales increased 8.2% in the U.S., 7.8% in Canada and 9.8% across Costco’s other international markets. Companywide comparable sales were up 8.4%.

Even after adjusting for changes in gasoline prices and foreign exchange rates, Costco’s overall comparable sales increased 6.6%.

The momentum also continued through the end of the year.

During Costco’s 16-week fourth quarter, net sales reached $93.9 billion, up 11.3% from $84.4 billion during the same period last year.

For August alone, Costco generated $23.7 billion in net sales, an increase of 9.9% from the previous year.

Costco’s Digital Business Is Growing Even Faster

Perhaps the most interesting number in Costco’s latest sales report is the growth in digitally enabled sales.

Those comparable sales increased 20.9% for the fiscal year and 19.5% during the fourth quarter.

Even in August, digitally enabled comparable sales were up 17.9%.

Costco uses the broader term “digitally enabled” rather than simply referring to traditional e-commerce sales, but the numbers make one thing clear: members are increasingly shopping Costco through digital channels.

For a retailer whose business has historically revolved around getting members inside a warehouse, that is a significant shift.

Costco has continued expanding the ways members can shop outside of a traditional warehouse visit, including through its websites and other digitally supported shopping options.

The company currently operates e-commerce sites in the United States, Canada, the United Kingdom, Mexico, Korea, Taiwan, Japan, Australia and China.

Costco’s Online Complements Costco’s Warehouse

The growth in digital sales doesn’t appear to be replacing Costco’s warehouses. Instead, both sides of the business are growing.

Costco currently operates 939 warehouses worldwide, including 647 locations in the United States and Puerto Rico.

That combination could be particularly powerful for Costco.

Members may still visit the warehouse for groceries, Kirkland Signature products, gas and the treasure-hunt experience Costco is known for, while using Costco’s website for items like furniture, appliances, electronics and products that may not be available at their local warehouse.

For shoppers, it’s another reminder that Costco.com and a local Costco warehouse don’t always carry the same products or offer the same prices.

Costco Is Closing In on $300 Billion

The sheer size of Costco’s annual sales is worth putting into perspective.

At $297.3 billion, Costco came within $2.7 billion of reaching $300 billion in annual net sales.

The company also added more than $27 billion in net sales compared with the previous fiscal year.

That growth comes as consumers continue to pay close attention to prices on groceries, household goods and other everyday expenses. Costco’s focus on value and bulk pricing continues to give shoppers a reason to keep coming back.

It also helps explain why Costco continues opening new warehouses in the U.S. and internationally.

What This Means for Costco Shoppers

Costco’s latest numbers show that the company isn’t just getting bigger. The way members shop Costco is also changing.

The warehouse will likely remain at the center of the Costco experience. Browsing the aisles and discovering something you never planned to buy is still a big part of the appeal.

But with digitally enabled comparable sales growing much faster than Costco’s overall comparable sales, the company’s online and digital business is becoming increasingly important.

For members, that could mean seeing even more products and shopping options online in the years ahead.

And if Costco continues growing anywhere close to its current pace, its first $300 billion net sales year may not be far away.

Costco is scheduled to report its full fourth-quarter and fiscal 2026 earnings results on September 24, which should provide an even closer look at the company’s performance.
