In the sprawling landscape of American retail, one private label has defied conventional wisdom to become a juggernaut that generates more revenue than Coca-Cola, Hershey’s, and Campbell Soup combined. It accounts for approximately a quarter of Costco’s annual sales, yet many consumers remain unaware of its unlikely origin story.
Kirkland Signature, Costco’s house brand, generated a staggering $58 billion in sales during the company’s latest fiscal year – making it America’s largest consumer packaged goods brand measured by sales. The product line spans an almost bewildering array of categories, from batteries and bacon to golf balls and gasoline.
“We always like to say consumers are ‘trading up’ when they buy Costco’s Kirkland Signature products instead of brand names,” said Jeff Marks, director of portfolio analysis at a major investment club, in a recent CNBC interview.
The brand’s genesis traces back to 1995, when Costco co-founder Jim Sinegal made a strategic decision that flew in the face of retail convention. While competitors maintained different private labels for various product categories – think Sears with Kenmore appliances, DieHard batteries and Craftsman tools – Sinegal envisioned consolidating everything under a single, recognizable name.
“The conventional wisdom said that you had to have a different name for every class of product that you had — a la Sears Roebuck with the Kenmore appliances and the DieHard batteries and the Craftsman tools,” Sinegal said in 2019.
Prior to the consolidation, Costco shoppers encountered roughly 30 different store brands, with forgettable names like Simply Soda, Chelsea toilet paper, and Clout detergent. The inspiration for change came partly from a 1991 Forbes article highlighting rising profit margins for leading consumer goods companies and the emerging growth of private labels.
Sinegal originally wanted to name the unified brand “Seattle Signature,” paying homage to the city where Costco opened its first store in 1983. When trademark approval proved impossible, the team pivoted to “Kirkland Signature,” after the Washington suburb where the company was headquartered at the time.
The name stuck even when the home office eventually moved to Issaquah — Sinegal cheekily pointed out that “nobody could spell Issaquah.”
This singular branding approach has delivered multiple advantages. Beyond simplifying legal clearances across international markets, it created instant recognition for consumers navigating Costco’s notoriously overwhelming warehouse format. The distinctive black, white, and red Kirkland logo serves as a beacon for shoppers seeking value without sacrificing quality.
Costco’s approach differs markedly from competitors like Target, which maintains 48 separate private brands, or Walmart, whose most recent own label covers 300 items in the food category alone.
What truly distinguishes Kirkland from typical store brands is its quality proposition. Rather than positioning items as merely cheaper alternatives, Costco aimed to match or exceed the quality of leading brands while maintaining prices 15-20% below branded alternatives.
As stated on Costco’s website: “Our mission was simple: Create an item of the same – or better – quality than the leading brand at a lower price, and do so by controlling every element of the item’s creation.”
This strategy has been implemented through partnerships with major manufacturers. While some suppliers decline to produce Kirkland versions of their products, others embrace the opportunity. Duracell manufactures Kirkland batteries, Starbucks roasts several Kirkland coffee varieties, and Huggies maker Kimberly-Clark produces Costco’s diapers.
The willingness of premium brands to collaborate with Kirkland underscores the label’s power. Some, like Jelly Belly, even opt for co-branding arrangements that prominently display both companies’ names on packaging.
Kirkland’s success has reverberated throughout the retail ecosystem. Its market clout has forced national brands to sharpen their pencils when setting prices. When Costco dropped the price on 40-count packages of bottled Kirkland water to $2.99, Poland Springs had little choice but to follow suit, according to reporting.
“Kirkland Signature keeps suppliers honest,” retail analyst Timothy Campbell told CNN.
Despite the brand’s extraordinary growth, Costco executives maintain a measured approach to expansion. Current CEO Ron Vachris recently stated the company is “not in a race to develop hundreds of Kirkland items” but evaluates opportunities on an “item-by-item basis.”
This disciplined strategy extends to quality control. Products that underperform with consumers are quickly removed or reformulated. When Kirkland Signature Light Beer launched in 2014 with moderate but underwhelming sales, the company didn’t hesitate to pull it from shelves.
Looking ahead, Vachris has identified non-food categories as Kirkland’s biggest growth opportunity. Though conventional wisdom suggests brand loyalty runs stronger in these segments, recent successes with motor oil and golf balls have emboldened the company.
As inflation pressures consumers across income brackets, Kirkland’s value proposition has only strengthened. According to a February survey by Ipsos Consumer Tracker, nearly three-quarters of U.S. adults believe private label products are equally good as name brand alternatives.
Perhaps most tellingly, this appeal transcends economic status. A third of respondents with household incomes above $100,000 reported increasing their store-brand purchases – nearly matching the 37% of middle-income shoppers doing the same.
From its unlikely beginning as a geographical compromise to its current status as retail royalty, Kirkland Signature demonstrates how a contrarian vision, consistent execution, and unwavering focus on quality can transform a store brand into a powerhouse that rivals the biggest names in consumer goods.
For a company that began with the simple goal of offering quality products at lower prices, Kirkland Signature has become something far more valuable: a brand that consumers actively seek out rather than merely accept as a cheaper alternative. In doing so, it has rewritten the rules of retail private labels, one rotisserie chicken and toilet paper mega-pack at a time.
