Definition
The interest coverage ratio divides operating profit (EBIT) by the annual interest charge. A ratio of 3 means profit covers interest three times over. Lenders use it to judge headroom — many look for at least 2 to 3 times — and it is a common loan covenant. It is closely related to, but distinct from, debt service cover, which also counts capital repayments.
In plain terms
It answers a simple question: if profit dipped, how far could it fall before you could not pay the interest? The higher the number, the more cushion.
