Interest Coverage Ratio

Leverage and Debt Ratios

Definition

The interest coverage ratio measures how easily a company can pay interest on its outstanding debt from its operating earnings. It divides EBIT (earnings before interest and taxes) by interest expense. A higher ratio means the company generates more operating profit relative to its interest obligations, indicating lower financial risk.

An interest coverage ratio of 5.0 means the company's operating earnings are five times its interest expense — it could absorb an 80% decline in operating earnings and still cover its interest payments. A ratio below 1.5 is generally considered risky, and a ratio below 1.0 means the company is not generating enough operating income to cover its interest expense, which is a significant warning sign.

This metric is especially important during periods of rising interest rates, when companies with floating-rate debt see their interest expense increase while their earnings may be flat or declining. The interest coverage ratio is a standard input to credit ratings and debt covenants.

Formula

Interest Coverage Ratio = EBIT (TTM) / Interest Expense (TTM)

How GeminIQ calculates this metric

GeminIQ divides trailing twelve-month EBIT by trailing twelve-month Interest Expense, both sourced directly from the company's SEC filings. If EBIT is not reported directly, it is derived from Net Income + Income Tax Expense + Interest Expense. Interest Expense uses the as-filed value, which may or may not include capitalized interest depending on how the company reports it.

FAQ

Q: What is a good interest coverage ratio?

A: Above 5.0 is generally considered strong. Between 2.0 and 5.0 is adequate for most industries. Below 1.5 indicates potential difficulty meeting interest obligations. Credit rating agencies typically consider ratios below 2.5 as a negative factor in investment-grade ratings.

Q: What does an interest coverage ratio below 1.0 mean?

A: A ratio below 1.0 means the company's operating earnings are insufficient to cover its interest expense. The company must use other sources — cash reserves, asset sales, or additional borrowing — to make its interest payments. This is a serious warning sign that may indicate financial distress, though it can be temporary during cyclical downturns for companies with strong balance sheets and adequate cash reserves.

Q: Why might interest coverage ratios differ between platforms?

A: The numerator (EBIT) and denominator (Interest Expense) are both sensitive to normalization decisions. Some aggregators use operating income rather than EBIT, which may exclude non-operating items differently. Some include capitalized interest in interest expense, others do not. GeminIQ uses the as-filed values for both and derives EBIT from Net Income + Income Tax + Interest Expense when it is not reported directly.
