The formulas
- Ratio = (EBITDA - unfinanced capex - cash taxes) / (cash interest + scheduled principal + other fixed charges)
- EBITDA needed = minimum x fixed charges + capex + cash taxes
- Cushion = EBITDA - EBITDA needed
How it works
A fixed charge coverage covenant tests whether earnings cover the payments the entity must make. Definitions vary by agreement, so use the exact defined terms in the credit agreement for each line, including permitted add-backs and the test period.
The cushion shows how far EBITDA can fall before the covenant is breached, holding the other lines fixed. Auditors use this when assessing covenant compliance for debt classification and going concern. A small cushion calls for a forecast and a waiver discussion.

Common questions
Why does the definition matter?
Credit agreements differ on what counts as EBITDA, capex and fixed charges. Follow the agreement.
What if a breach is likely?
Consider debt classification as current and the going concern disclosure, and ask whether a waiver has been obtained.
Are taxes held fixed in the cushion?
Yes. In reality taxes fall with earnings, so the cushion is a conservative estimate.
