Headroom / Guides
What is covenant headroom?
Covenant headroom is the distance between a borrower's actual result on a financial covenant and the limit in its credit agreement: how much room is left before a breach. For a maximum covenant it is (limit − actual) ÷ limit; for a minimum covenant, (actual − limit) ÷ limit. A leverage ratio of 3.71x against a 4.00x maximum has 7.2% headroom, or 0.29 turns, which here means covenant EBITDA could fall about $3.95 million before a breach.
The formula
Financial covenants come in two shapes, and headroom is measured differently for each.
Maximum covenants
Leverage ratios, where lower is better. The borrower must stay below the limit.
Headroom = (limit − actual) ÷ limit
Minimum covenants
Interest or fixed-charge coverage, where higher is better. The borrower must stay above the limit.
Headroom = (actual − limit) ÷ limit
Lenders also quote headroom in turns, the plain difference between the ratios: 4.00x − 3.71x = 0.29x. A covenant that has already been breached has negative headroom.
A worked example
Take a borrower whose credit agreement caps Total Net Leverage at 4.00x and requires Interest Coverage of at least 2.00x. These are the numbers from Headroom's sample review of a fictional company, in millions:
| Consolidated Total Net Debt | $205.0 |
| Consolidated EBITDA before capped add-backs | $46.0 |
| Capped add-backs allowed (20% of $46.0) | $9.2 |
| Consolidated EBITDA per the agreement | $55.2 |
Leverage: $205.0 ÷ $55.2 = 3.71x against a 4.00x maximum. Headroom is (4.00 − 3.714) ÷ 4.00 = 7.2%, or 0.29 turns.
Coverage: the same borrower's Interest Coverage is 6.90x against a 2.00x minimum. Headroom is (6.90 − 2.00) ÷ 2.00 = 245%.
Be careful comparing those two percentages. 245% is distance from the limit, not how far earnings can fall. In EBITDA terms, coverage breaches when EBITDA falls 1 − 2.00 ÷ 6.90 = 71%. For leverage the two measures agree (both 7.2%); for coverage they don't. To compare covenants with each other, compare their EBITDA cushions.
EBITDA cushion: how far earnings can fall
For a leverage covenant, the breach point is the EBITDA at which debt divided by EBITDA equals the limit.
EBITDA cushion = covenant EBITDA − (net debt ÷ limit)
In the example: $55.2 − ($205.0 ÷ 4.00) = $55.2 − $51.25 = about $3.95 million. Covenant EBITDA can fall by that much before the borrower breaches.
The detail most spreadsheets miss. When add-backs are capped as a percentage of EBITDA, the cap shrinks as EBITDA falls, so each $1 of lost operating EBITDA removes $1.20 of covenant EBITDA. If you hold add-backs at a fixed $9.2 million, operating EBITDA can fall $3.95 million. With the cap moving, it can fall only $3.3 million, to $205.0 ÷ (4.00 × 1.2) = $42.7 million: about 17% less room than a fixed-add-back model shows. This assumes claimed add-backs stay above the cap, which they do here ($16.0 million claimed against $8.5 million allowed at the breach point). If the cap is measured after add-backs, the multiplier is 1 ÷ (1 − 20%) = 1.25, not 1.2.
Leverage-covenant debt capacity
Debt capacity = (limit × covenant EBITDA) − net debt
In the example: (4.00 × $55.2) − $205.0 = $15.8 million of additional net debt before the leverage covenant is breached, assuming EBITDA holds. Two caveats: borrowed cash left on the balance sheet may be netted against debt (often subject to a cap), and whether new debt can actually be incurred is governed by the agreement's debt covenant, its baskets and incurrence ratios, not by this maintenance test.
Step-downs: headroom you have today may be gone next quarter
Many agreements tighten their limits over time on a schedule. In the example the maximum steps from 4.00x to 3.75x on December 31, 2026. At today's numbers, headroom against the new limit is (3.75 − 3.714) ÷ 3.75 = about 1.0%. Nothing about the business changed. The covenant did.
Some agreements also loosen the limit for a period after a material acquisition (an acquisition step-up), and the borrower usually has to elect it. Both need to be on the calendar, not discovered at quarter-end.
Why the credit agreement's definitions change the answer
Covenant EBITDA is not the EBITDA in the financial statements. Each agreement defines Consolidated EBITDA, debt and every ratio in its own words, usually in Section 1.01, with:
- permitted add-backs, such as run-rate cost savings, restructuring charges and non-cash compensation,
- caps on some of those add-backs, often as a percentage of EBITDA,
- limits on how much cash can be netted against debt,
- pro forma adjustments for acquisitions and dispositions.
Here is the clause behind the example's cap:
…provided that the aggregate amount added back pursuant to this clause (d) shall not exceed 20% of Consolidated EBITDA for such Test Period (calculated before giving effect to such add-backs)…
Section 1.01, “Consolidated EBITDA,” clause (d)
If the draft compliance certificate adds back all $16.0 million of claimed cost savings and restructuring, it shows leverage of $205.0 ÷ $62.0 = 3.31x. The agreement allows only $9.2 million, which gives 3.71x. Same company, same quarter, two different answers, and only one of them is what the lender will accept.
Springing covenants and equity cures
Springing covenants are tested only when a condition is met. In cash-flow revolvers, a leverage test commonly springs when revolver usage exceeds a threshold (often 35 to 40%) at quarter-end, and often only the revolving lenders can enforce it. In asset-based (ABL) facilities, a fixed-charge coverage test typically springs when excess availability falls below a threshold. The fictional sample agreement uses a revolver-usage trigger for its Fixed Charge Coverage Ratio: at 30% usage against a 35% trigger it wasn't tested, but five points of extra revolver usage would bring it into play, so the trigger itself needs headroom too.
Equity cures let a sponsor contribute cash after quarter-end that is deemed added to EBITDA for the covenant test (some agreements apply it to reduce debt instead). They are commonly limited, for example to two cures in any four consecutive quarters with a lifetime cap, and to the amount needed to cure, and the cured EBITDA usually doesn't count for baskets or pricing. A cure is a fix after the fact, not headroom.
Frequently asked questions
Is covenant headroom the same as covenant cushion?
Yes. The terms are used interchangeably. Some people use "cushion" for the dollar version (how far EBITDA can fall) and "headroom" for the percentage, but both describe the room left before a breach.
What counts as tight headroom?
There is no universal threshold. It depends on how volatile the business is and what the next step-down looks like. Comparing EBITDA cushions works across covenant types; Headroom flags a covenant as tight when it is within 15% of its limit, and always checks headroom against the next step-down as well as the current limit.
Who calculates covenant headroom?
The borrower's finance team calculates it every quarter for the compliance certificate its officer signs. Lenders recompute it from the certificate and financials to monitor their loans. Private equity sponsors track it across their portfolio companies.
Can I use the EBITDA from my financial statements?
Only as a starting point. Covenant EBITDA follows the credit agreement's definition, including its add-backs, caps and pro forma adjustments, and the result can differ from reported EBITDA by a wide margin.
