Frequently Asked Questions
What does the Interest Coverage Ratio tell you?
It reveals how comfortably a business can pay the interest due on its borrowings. Higher numbers indicate a thicker margin of safety before an operational downturn impairs interest payments.
What is the difference between DSCR and Interest Coverage?
Interest Coverage only examines interest expense, whereas DSCR includes both interest expense and mandatory principal debt repayments.
What is a dangerous Interest Coverage Ratio?
An interest coverage ratio below 1.5x signals dangerous balance sheet vulnerability. If operating profits dip even slightly, the firm will face liquidity shortfalls or debt covenant violations.
