A higher ratio is generally considered better. The ratio for FY2025 is a trailing twelve months figure. Over the past several years, Costco's ability to cover its interest expenses with its operating income has shown a strong and consistent upward trend. For the quarter ending in May 2025, the interest coverage ratio was 72.29. This demonstrates a significant improvement in the company's financial health regarding its debt obligations. The operating income for the twelve months ending May 31, 2025, was $10.084 billion.
