Costco Wholesale Corp (NASDAQ:COST | COST Price Prediction) just reported something remarkable: a 92.3% renewal rate in the US and Canada, with 89.8% worldwide. That’s not just a metric. It’s the entire business model distilled into two numbers.
Most retailers live and die by comparable sales or margin expansion. Costco’s stickiness lives in membership renewal. When nine out of ten customers voluntarily write another check each year, you’ve built something Amazon.com Inc (NASDAQ:AMZN) and Walmart Inc (NYSE:WMT) can’t easily replicate.
Why This Number Matters More Than Revenue
Membership fees are nearly pure profit. Costco’s 2.96% profit margin on merchandise sales looks anemic until you realize membership income grew 14% year-over-year. That high-margin recurring revenue subsidizes razor-thin retail pricing, which keeps members renewing. It’s a flywheel, not a treadmill.
CFO Gary Millerchip explained the recent dip from historical 93% levels: “The decline in renewal rates was largely attributable to a higher number of online sign-ups entering the renewal rate.” Translation: Costco is acquiring younger members digitally. Nearly half of new sign-ups are now under age 40. They renew at slightly lower rates initially but represent decades of future lifetime value.
What to Watch
Bullish: Executive membership upgrades accelerating. Executive members grew 9.3% year-over-year and drive 74.2% of worldwide sales despite being only 47.7% of paid members. New perks like extended shopping hours and Instacart credits are driving upgrades.
Bearish: If online-acquired members don’t eventually match warehouse renewal rates, the mix shift could pressure the metric long-term.
The Verdict
A 92% renewal rate means Costco doesn’t just sell groceries. It sells a relationship customers choose to maintain year after year, creating predictable cash flow that funds expansion and shareholder returns while competitors chase quarterly comps.
