Interest Coverage Ratio

The interest coverage ratio (also called times interest earned) measures a company's ability to pay interest on its outstanding debt. It is calculated as EBIT (Earnings Before Interest and Taxes) divided by Interest Expense. A ratio of 5x means the company earns five times its interest obligations — a comfortable margin of safety. Below 1.5x is generally considered dangerous, while below 1.0x means the company cannot cover its interest payments from operating earnings.

This ratio is one of the most important metrics for credit analysis and debt investors. Bond rating agencies like Moody's, S&P, and Fitch heavily weight interest coverage when assigning credit ratings. Investment-grade companies (BBB/Baa or above) typically maintain interest coverage ratios above 3x, while highly-rated companies often exceed 8-10x. Loan covenants frequently require minimum interest coverage ratios, and breaching these covenants can trigger technical default.

For equity investors, the interest coverage ratio provides insight into financial risk and flexibility. Companies with high interest coverage can comfortably take on additional debt for acquisitions or share repurchases. Those with low coverage have limited financial flexibility and face existential risk during earnings downturns. The ratio should be assessed as a trend and in context — a declining interest coverage ratio from 8x to 4x is concerning even though 4x is still adequate. Some analysts use EBITDA instead of EBIT for a more conservative measure, since depreciation and amortization are non-cash charges. Industry context matters too — regulated utilities can safely operate with lower coverage because their revenues are predictable.
