A $10,000 investment in Costco stock ten years ago would now be worth $72,000 due to consistent compounding and high renewal rates.
A $10,000 investment in Costco Wholesale (NASDAQ: COST) a decade ago, with dividends reinvested, would now be valued at approximately $72,000. The retailer’s shares, trading near $155 ten years ago, delivered an average annual return of 22%, driven by its membership-based business model.
Costco’s model relies on annual membership fees, which provide recurring high-margin revenue and incentivize low prices to retain customers. Renewal rates hover around 90%, sustaining growth across economic cycles. In the fiscal third quarter ending May 10, 2026, net sales rose 11.6% year over year to $69.2 billion, with May’s monthly sales up 14.5%.
The company’s ability to compound returns stems from a flywheel effect: low prices drive traffic, loyalty boosts renewals, and renewals fund further price reductions.
