Costco Broadens Audience While Tightening Membership

Over the past two years, Costco has made several moves that risked upsetting its famously loyal customer base – including raising membership fees in September 2024 and restricting food court access to members only. But visit data suggests that, rather than deterring shoppers, these changes have supported rising engagement and a broadening customer base.

Visits Stay Resilient

The chart below shows that Costco entered 2026 with solid visit momentum. Both total and same-store visits posted healthy year-over-year gains through the back half of 2025 and into January.

That resilience aligns with recent earnings reports, which show Costco delivering consistent mid-single-digit comparable sales growth throughout 2025. By raising the “cost of commitment,” Costco may be discouraging casual or opportunistic users while deepening engagement among shoppers who do the math and shop more frequently to justify the fee.

A Younger, Broader Audience

Perhaps the clearest signal of Costco’s durable positioning lies in its evolving demographic profile. While the chain continues to over-index on affluent consumers, it is also attracting a growing cohort of younger shoppers, reflected in the chart below by a rising share of “Contemporary Households” – a young-skewing segment comprising singles, married couples without children, and non-family households. As this cohort has expanded, Costco’s overall income profile has also subtly broadened.

The persistence of this shift despite higher fees challenges the notion that price increases drive exclusivity. For many households, the fee remains a rational trade-off for reliable savings – and the broader reach gives Costco added leverage to negotiate pricing and defend margins.

The Bottom Line

Costco’s recent moves show that pricing power and scale don’t have to be trade-offs. By pairing higher fees with stricter enforcement, the company is strengthening loyalty, preserving value perception, and widening its appeal to younger households – all while keeping traffic strong. That combination leaves Costco unusually well positioned as cost pressures persist: a retailer with both the volume to command supplier leverage and a member base committed enough to sustain it.
