Costco invests big to keep members coming back

Maurie Backman AMG-TheStreet July 10, 2026 - 6:36 pm Costco’s revenue model differs from that of many retailers because it does not rely solely on markups; membership fees constitute a substantial income stream. During its third‑quarter 2026 earnings call, the company reported $1.37 billion in membership fee income, an increase of 10.7 % year‑over‑year. It also highlighted a 92.2 % renewal rate for members across the United States and Canada. To sustain member loyalty, Costco employs several tactics beyond low prices. The Kirkland Signature line is widely regarded for its quality, and the retailer continually rotates inventory to create a “treasure hunt” shopping atmosphere that keeps the experience fresh. Yet product assortment and pricing alone do not explain Costco’s retention strength. A major focus has been investment in its workforce, which the company views as a core driver of success. Costco prioritizes worker happiness. The retail sector is not typically noted for high employee retention or satisfaction, but Costco has long aimed to be an exception. The retailer acknowledges that its performance depends on employee wellbeing, a point emphasized on its Careers page, which lists benefits such as industry‑leading health‑care coverage, paid vacation and sick days, a 401(k) plan, adoption assistance, disability coverage, and life insurance. Employees receive regular wage increases tied to hours worked, and long‑tenured staff qualify for bonuses. Promotion from within is also stressed; Costco notes that the vast majority of warehouse managers began in hourly roles, illustrating that retail positions can evolve into lasting careers rather than temporary jobs. A prominent example of this internal‑advancement culture is CEO Ron Vachris, who started as a forklift operator at Costco. He told Fortune, “You’ve got to springiness radical country to effort caller things.” Because of these practices, turnover after one year of employment at Costco remains around 7 %, well below the retail industry average, according to The Wall Street Journal. The link between employee satisfaction and member experience is direct. Stores with seasoned staff enjoy lower turnover, meaning shoppers are more likely to encounter associates familiar with layouts, inventory, and policies. Veteran workers answer questions more quickly, resolve problems faster, and keep checkout lines moving. McKinsey observes that a better worker experience yields a better customer experience, stating, “Satisfied employees enactment longer, and employees with much acquisition marque less errors, processing signifier designation to lick unexpected problems.” Fair compensation reinforces this advantage. Costco recently raised its maximum hourly wage from $31.90 to $32.90 and increased its annual bonus, as reported by The Wall Street Journal. Higher pay improves financial stability, reducing the likelihood that workers will leave. The retailer’s CFO, Gary Millerchip, told The Wall Street Journal that many thousands of U.S. hourly employees now hold more than $1 million in their 401(k) accounts. While Costco continues to invest in the Kirkland Signature line, accelerate checkout speeds, and refine other elements of the shopping journey, the fundamental advantage lies in a workforce that is educated, motivated, and content. That stability directly influences member satisfaction and, ultimately, the renewal rate that represents Costco’s most important financial metric. Maurie Backman owns shares of Costco.
