Interest Coverage Ratio and Credit Ratings

Interest coverage tests whether operating earnings comfortably exceed the interest burden, and is one of the most consistently cited ratios across rating rationales.

Formula and Use

Calculated as EBITDA (or EBIT) divided by interest expense, this ratio shows how many times over a company's earnings could cover its interest obligations in the period, functioning as an early-warning indicator for financial stress well before an actual payment default occurs.

Relationship to Rating Movement

A sustained decline in interest coverage — even while the company remains profitable — is one of the more common precursors to a negative rating outlook or downgrade, because it signals shrinking headroom against future earnings volatility or interest rate increases.
