Inflation Just Hit 3.8% and Nine Out of Ten Costco Members Re-Up Every Year. Here Is Why That Math Matters.

Costco ended Q2 FY2026 with 82.1 million paid memberships and an 89.7% worldwide renewal rate, showing stability across quarters. Membership fee income totaled $1.355 billion, up 13.6% year over year, and Executive members generated 75.8% of sales. About nine in ten members renew annually, creating a cash flow profile similar to a subscription model. FY2025 results included $275.235 billion in revenue, $8.099 billion in net income, and $7.837 billion in free cash flow, with EPS of $18.21. The company returned capital through $903 million in buybacks in FY2025 and $419 million in the first 24 weeks of FY2026, while maintaining a cash balance of $17.383 billion. Inflation measures accelerated in early 2026, and Costco’s bulk pricing and private label products tend to gain wallet share when grocery and gasoline costs rise.

Shareholders' equity climbed to $32.087 billion, up 25.45% year over year, while cash on the balance sheet reached $17.383 billion, up 40.68%."

April CPI hit 333.020, the fourth straight monthly increase. The inflation rate is now 3.8% and more than expectations.
