What it means
The ratio exists because lenders want a cash-flavoured view of affordability. Depreciation and amortisation are real economic costs but they are not payments, so removing them shows more of the profit that could genuinely be used to service debt.
It matters most for capital-intensive businesses. Telecoms networks, hotels and manufacturers carry very large depreciation charges, and measuring their interest cover on EBIT alone can make a perfectly solvent business look precarious.
The calculation itself is simple division, and the practical work lies in getting EBITDA right. Start from operating profit, add back depreciation and amortisation, and be careful to use the interest actually charged rather than a net figure that offsets interest income.
Lenders write this ratio into loan documents as a covenant alongside leverage tests such as net debt to EBITDA. Typical minimums sit somewhere between 2.0 and 4.0 times, with the exact level reflecting how predictable the company's earnings are.
The nuance is that EBITDA overstates the cash a business can safely divert to interest. If equipment genuinely wears out, the money to replace it has to come from the same profit, so a comfortable EBITDA ratio sitting alongside a weak EBIT ratio is a signal to look harder.
A sensible habit is to calculate both versions and compare the gap. A wide gap tells you the business depends heavily on assets that will need replacing, while a narrow gap means the two measures are telling much the same story and either can be quoted safely.
In practice
Real-world examples.
Example
A telecoms operator with heavy network depreciation reports EBITDA of $50,000,000 against interest of $10,000,000, giving coverage of 5.0 times. Its EBIT-based cover is far lower, which is why its lenders write the covenant on the EBITDA measure and set the required level higher to compensate.
Example
A software firm has EBITDA of $9,000,000 with only $500,000 of depreciation and amortisation, and pays interest of $3,000,000. Coverage is 3.0 times on EBITDA and $8,500,000 / $3,000,000 = about 2.83 times on EBIT, so the two measures barely differ in an asset-light business.
Example
A hotel group with a covenant set at 3.5 times sees EBITDA fall from $14,000,000 to $10,500,000 while interest stays at $3,000,000. Coverage drops from about 4.67 times to exactly 3.5, putting the group right on its covenant limit with no margin left.
Think of it
“EBITDA interest coverage uses cash-like earnings to show interest coverage-before depreciation effects.
Formula
Calculation
EBITDA Interest Coverage Ratio = EBITDA / Interest Expense
A mid-sized manufacturer reports EBIT of $4,800,000 and depreciation and amortisation of $2,400,000, so EBITDA is $4,800,000 + $2,400,000 = $7,200,000. Interest expense for the year is $1,800,000. The EBITDA interest coverage ratio is $7,200,000 / $1,800,000 = 4.0 times. Measured on EBIT instead, coverage is $4,800,000 / $1,800,000 = about 2.67 times, and the gap between the two figures is exactly the effect of the depreciation charge.Case study
Seen in the real world.
Kestrel Park Fitness is a fictional gym operator created purely to illustrate the ratio. It reported EBITDA of $4,000,000 against interest of $800,000, giving coverage of 5.0 times, which the management team presented to the board as evidence of a strong balance sheet.
A new finance director asked what happened after depreciation. With annual depreciation and amortisation of $2,600,000, EBIT was only $1,400,000 and EBIT-based interest cover was $1,400,000 / $800,000 = 1.75 times, a very different story.
The depreciation was not an accounting fiction in this illustrative case, because gym equipment genuinely needed replacing and maintenance capital expenditure was running at about $2,000,000 a year. The board began reporting both ratios side by side and slowed its expansion plan until the gap between them narrowed. In this fictional example the lender welcomed the change, because it made the reporting pack match the way credit teams already looked at the business.
Watch out
Common mistakes.
- Presenting EBITDA interest cover on its own when depreciation reflects assets that genuinely need replacing every few years.
- Netting interest income against interest expense in the denominator, which overstates coverage for companies holding large cash balances.
- Using a full-year EBITDA figure against a part-year interest charge after new borrowing, which flatters the ratio in the year a loan is drawn.
Questions
People also ask.
Why do lenders prefer EBITDA to EBIT here?
Because interest is paid in cash and depreciation is not a cash cost, so EBITDA is closer to the money actually available to pay it.
What is a safe level for this ratio?
Above 3.0 times is generally comfortable for a stable business, while anything under 2.0 leaves very little room if trading weakens.
Does the ratio include capital repayments?
No, it covers interest only, so pair it with a debt service or EBITDA coverage ratio if you want to test the full repayment obligation rather than just the cost of carrying the debt.
