What is covenant headroom?

Covenant headroom, also called covenant cushion, measures how much room a borrower has before breaching a financial covenant. It can be expressed as the difference between the actual ratio and the threshold, as a percentage of the threshold, or as the amount by which a key input, often EBITDA, could decline before a breach occurs.

Lenders track headroom to identify borrowers that are drifting toward a breach before it happens. Thin or shrinking headroom across consecutive test periods is a common watch list trigger. At origination, lenders set covenant levels to leave reasonable headroom against the borrower's projections, so that normal volatility does not cause a technical default.

Headroom measured only at the testing date can miss seasonal swings and intra-period deterioration. Calculating it with figures that do not match the covenant definitions, such as unadjusted EBITDA, produces misleading results. Analysts should also watch for scheduled covenant step-downs, where the threshold tightens over time, which can erase headroom even when performance is stable.
