Costco's Digital Sales Growth Outpaces Overall Business in Fiscal 2026
In its fiscal year ending August 30, 2026, Costco Wholesale (NASDAQ: COST) reported that digitally enabled comparable sales grew by 20.9% year-over-year — more than double the overall business growth of 8.4%. These digital sales now account for nearly 10% of total net sales and surpassed $27 billion in fiscal 2025, indicating a significant shift toward online engagement. Costco is leveraging digital tools to enhance member experiences rather than replacing its physical warehouses entirely. Personalized recommendation features on Costco's platforms drove e-commerce sales exceeding $498 million during the third quarter of fiscal 2026 and converted at three times the typical rate. However, these digital initiatives carry lower gross margins compared to traditional warehouse operations. While digital growth remains strong — with year-over-year increases in Q4 reaching 19.5% — it is slowing slightly from earlier gains. Costco's stock currently trades at a high valuation of around 40.8 times estimated fiscal 2027 earnings, raising questions about whether the company can sustain its rapid digital growth while maintaining profitability.
