Note: The inventory turnover ratio indicates how many times a company's inventory is sold and replaced over a period. Costco's fiscal year ends in August. The figure for fiscal year 2025 is an estimate based on the trailing twelve months (TTM) data as of May 2025. The historical data for fiscal years 2020 through 2024 reflects the company's performance as reported in financial analyses. For instance, after a decrease in 2022 and 2023, the turnover increased in 2024.
