What it means
EBITDA is a convenient stand-in for the cash a business throws off before financing and accounting choices get involved, which makes it a common yardstick for debt capacity. Net debt is what would remain owing if all spare cash went to lenders tomorrow.
Dividing one by the other produces a single number that most boards can interpret without any finance training. As a rough guide, ratios below 2.0 times are usually considered conservative, 2.0 to 3.5 times is normal for a stable profitable business, and figures above 4.0 times start to make lenders uncomfortable.
The tolerable level depends heavily on the sector, since utilities and property companies with contracted cash flows carry far more than cyclical manufacturers or early-stage firms. Almost every bank loan agreement contains a leverage covenant expressed in these terms and tested each quarter.
Breaching it can trigger a higher interest margin, blocked dividends or, in the worst case, an immediate demand for repayment. Finance teams therefore forecast the ratio months ahead and time capital spending and distributions around the test dates.
The main weakness is that EBITDA ignores real costs. A company that must replace machinery every few years has genuine cash outflows that EBITDA quietly excludes, so two firms sitting at 3.0 times can have very different capacity to actually repay.
Careful analysts read the ratio alongside free cash flow and interest cover before drawing conclusions. Definitions also vary more than newcomers expect, because lenders often permit an adjusted or pro forma EBITDA that adds back one-off costs and includes a full year of earnings from recent acquisitions.
Those adjustments can move the ratio by half a turn or more, so it is always worth asking which definition a quoted figure uses.
In practice
Real-world examples.
Example
A craft brewery with EBITDA of $8,000,000 and net debt of $10,000,000 wants to buy a rival for $20,000,000 funded entirely by new borrowing. Pro forma net debt becomes $30,000,000 against combined EBITDA of $11,000,000, a ratio of about 2.7 times, which its bank is willing to support.
Example
A buyout fund models an acquisition at 5.0 times net debt to EBITDA on the day it completes, planning to reach 3.0 times within three years through earnings growth and scheduled repayments. The projected exit valuation depends heavily on whether that path holds.
Example
A hospitality group's finance director shows the board eight quarters of net debt to EBITDA rising from 2.1 to 3.4 times as a refurbishment programme flowed through. The board pauses the remaining refurbishments rather than risk approaching the 4.0 times covenant.
Formula
Calculation
Net Debt to EBITDA = (Total Debt - Cash and Cash Equivalents) / EBITDA
A regional food distributor has total borrowings of $90,000,000 and cash of $15,000,000, so net debt is $90,000,000 - $15,000,000 = $75,000,000. EBITDA for the last twelve months was $25,000,000.
The ratio is $75,000,000 / $25,000,000 = 3.0 times.
Its banking covenant caps the ratio at 3.5 times. At current earnings, net debt could reach 3.5 x $25,000,000 = $87,500,000 before a breach, leaving $87,500,000 - $75,000,000 = $12,500,000 of headroom. The risk runs the other way too: if EBITDA fell to $20,000,000 with net debt unchanged, the ratio would jump to $75,000,000 / $20,000,000 = 3.75 times and the covenant would be breached without the company borrowing another dollar.Case study
Seen in the real world.
Larkfield Components is a fictional manufacturer used here for illustrative purposes. It closed its financial year with net debt of $48,000,000 and EBITDA of $16,000,000, giving a ratio of 3.0 times against a covenant limit of 4.0 times, which management described to the board as comfortable.
A major customer then delayed a large contract, and the forecast for the following year fell to EBITDA of $12,000,000. At unchanged net debt the ratio would reach $48,000,000 / $12,000,000 = 4.0 times, sitting exactly on the covenant with no margin for a further disappointment.
Rather than wait and hope, the finance director sold a surplus warehouse for $9,000,000 and applied the proceeds to the term loan, cutting net debt to $39,000,000. The forecast ratio dropped to $39,000,000 / $12,000,000 = 3.25 times, and the company kept its banking arrangements intact through the downturn.
Watch out
Common mistakes.
- Reading the ratio as a literal repayment schedule, when interest, tax and capital spending all take their share of EBITDA long before any of it reaches lenders.
- Comparing the ratio across very different industries without adjusting expectations for how predictable each sector's cash flows really are.
- Testing a covenant using statutory EBITDA when the loan agreement specifies an adjusted definition with permitted add-backs.
Questions
People also ask.
What is a good net debt to EBITDA ratio?
For most stable trading businesses something between 1.5 and 3.0 times is comfortable, while capital-intensive sectors with long contracted revenue routinely carry more.
Does the ratio use current or trailing earnings?
Lenders normally test it against the last twelve months of EBITDA, sometimes adjusted for acquisitions completed part-way through the period.
What happens if a covenant is breached?
In practice most breaches are resolved through a waiver, a fee and a repricing rather than repayment, but the lender gains negotiating power and the company usually accepts tighter conditions.
