How do you learn net debt to EBITDA quickly and correctly? Imagine a business has borrowed money, but also holds cash that might be available to reduce that debt. Investors and lenders sometimes compare the net amount of borrowing with the company’s annual earnings before interest, taxes, depreciation and amortisation. The result is the net debt-to-EBITDA ratio, a common leverage indicator. It is simple to calculate but easy to misunderstand, because EBITDA is not free cash flow and not every reported cash balance is unrestricted. This eduKateSG Finance Quick Notes lesson teaches the numerator, denominator, and an easy S$1 million net-debt example.
- Total financial debt: relevant interest-bearing short-term and long-term debt.
- Net debt: total included financial debt minus the eligible cash and cash equivalents in the stated definition.
- EBITDA: earnings before interest, taxes, depreciation and amortisation.
- Formula: net debt ÷ annual EBITDA.
- Interpret 2.5×: measured net debt equals two and a half times the annual EBITDA figure.
- Not a repayment promise: it does not say every dollar of EBITDA is available to retire debt.
- Check exclusions: restricted cash, leases, unusual earnings and covenant definitions matter.
Teaching paragraph 1 — calculate financial borrowing before subtracting cash. Suppose a fictional company reports S$200,000 of short-term financial borrowing and S$1,000,000 of long-term interest-bearing debt. The total debt included in our example is S$1.2 million. The company also holds S$200,000 of unrestricted cash and cash equivalents assumed eligible for the calculation. Subtract: S$1.2 million − S$200,000 = S$1 million net debt. We are not subtracting receivables, inventory or the value of factories, because the chosen net debt definition uses cash-like items rather than every asset shown on the balance sheet.
Teaching paragraph 2 — divide net debt by the EBITDA measure. Imagine the company generated S$400,000 in annual EBITDA, correctly constructed for the relevant reporting period. Divide S$1 million by S$400,000 and the ratio is 2.5×. The number compares a balance-sheet debt position at a date with an annual earnings measure. People sometimes loosely describe this as ‘years of EBITDA’, but it is not an actual repayment time. EBITDA excludes capital spending, interest, taxes and working-capital cash movements, so no one has proved the company could pay off all the debt in two and a half years.
Teaching paragraph 3 — watch the ratio change when cash or earnings fall. Suppose net debt remains S$1 million but annual EBITDA drops to S$250,000. Net debt to EBITDA rises from 2.5× to 4.0×. The numerator is unchanged; the denominator fell. Alternatively, if the same business adds S$200,000 of genuine unrestricted cash without increasing its debt, net debt could fall to S$800,000 and the multiple become 2.0× at S$400,000 EBITDA. Different causes can change one ratio. Look separately at borrowing, cash and earnings before deciding what the trend means.
The Two-Step Net Debt to EBITDA Formula
Net debt = total included interest-bearing debt − eligible cash and cash equivalents. Then net debt-to-EBITDA = net debt ÷ annual EBITDA. Some published measures include additional liquid investments or particular lease obligations, while others exclude restricted cash and apply different accounting treatments. Read the stated definition or loan covenant before comparing a company with a peer.
Your First Net Debt to EBITDA Example
- Short-term included financial borrowings: S$200,000.
- Long-term included financial borrowings: S$1,000,000.
- Total included debt: S$1,200,000.
- Unrestricted eligible cash and cash equivalents: S$200,000.
- Net debt: S$1,000,000.
- Annual EBITDA: S$400,000.
- Ratio: S$1,000,000 ÷ S$400,000 = 2.5×.
- At S$250,000 EBITDA and unchanged net debt: 4.0×.
These are imaginary numbers, not figures from a real issuer. The business’s financial statements may also show trade payables, pension obligations, provisions, lease liabilities and other claims. Whether those items enter a particular credit or valuation metric depends on the definition being used. A useful calculation clearly labels the included items instead of silently calling every obligation ‘net debt’.
What Is Gross Debt?
Gross financial debt means the included borrowings before deducting cash. It may include bank loans, bonds and other interest-bearing obligations. In our example gross debt is S$1.2 million. A company could have substantial gross debt while keeping a cash reserve for future payments. Net debt adjusts that gross position for qualifying liquid funds, making it a different leverage measure. Neither automatically reveals when each loan is due.
What Is Net Debt?
Net debt is not the same as total liabilities. A company’s liabilities can include supplier payables, taxes and customer contract obligations, in addition to financial borrowing. A standard simplified net debt calculation focuses on interest-bearing debt minus cash and cash equivalents. Depending on lender and analyst conventions, qualifying short-term investments and lease liabilities may be handled differently. The chosen treatment must be described before relying on the ratio.
Why Cash Must Be Truly Available
A balance labelled cash can include money restricted for collateral, held in a legally controlled account or otherwise unavailable for ordinary repayment. Simply subtracting every reported cash amount may overstate the resources that can be used to reduce financing obligations. In lender analysis, whether money is eligible for netting depends on legal access, account arrangements and the specified covenant rules. Always look for restrictions and ask whose cash it actually is.
How to Understand EBITDA
EBITDA stands for earnings before interest, taxes, depreciation and amortisation. It is often calculated by adding these specified expenses back to an appropriate net income figure, using consistent definitions. It is not strictly cash flow, because customers may owe money and the company may need to buy machinery. For the standalone lesson on the denominator, see How to Learn EBITDA Quickly and Correctly.
Why Higher Net Debt to EBITDA Can Be a Warning
A larger multiple can indicate more net borrowing relative to the annual EBITDA measure. A company with declining earnings or substantial debt could face more pressure to refinance, meet covenants or make payments. But the same multiple can mean different levels of risk in a stable utility, a rapidly growing enterprise or a cyclical manufacturer. Review the type of business, interest expense, cash needs and economic conditions rather than using one threshold for every industry.
Why Lower Is Not Automatically Better
Lower net debt may reflect a prudent balance sheet, but an excessively simple comparison ignores why a company borrows. Borrowing can finance productive assets and expansion when managed responsibly. A low multiple could also result from temporarily high EBITDA that will not continue. Conversely, a negative net debt amount may arise when cash exceeds financial borrowings, but that does not prove every other business or contractual risk is absent.
What If Net Debt Is Negative?
Suppose the company has S$300,000 in debt and S$500,000 of qualifying cash. Net debt is −S$200,000, sometimes called a net cash position. If annual EBITDA were S$400,000, mechanical division would produce −0.5×. It is often more informative to describe the net cash position explicitly than treat the negative multiple like an ordinary positive leverage measure. Check cash restrictions and other obligations before assuming financial safety.
What If EBITDA Is Zero or Negative?
If EBITDA is zero, the division is mathematically undefined. If EBITDA is negative, a negative multiple may not describe normal repayment capacity in a meaningful way. A company with positive net debt and negative EBITDA requires a closer examination of cash burn, funding and the prospects for future earnings. Do not label a strange negative result as ‘cheap debt’ or a sign of good credit health.
Net Debt to EBITDA Is Not a Repayment Schedule
The company cannot normally devote all EBITDA to repaying financial debt. It must pay appropriate taxes, interest, operating commitments and capital expenditure, and may need working capital. The multiple also says nothing about whether S$100,000 or S$900,000 of debt falls due next month. Examine the financial-statement debt note and cash-flow forecast. The ratio is a comparison of scale, not proof of a particular payoff date.
Compare with Interest Coverage
Interest coverage often compares EBIT with interest expense over a period, while net debt to EBITDA compares a net borrowing balance with annual EBITDA. The former focuses on earnings relative to interest cost; the latter focuses on debt burden relative to an earnings proxy. A company could have 2.5× net debt to EBITDA but only weak coverage if interest rates are high. Read How to Learn Interest Coverage Ratio Quickly and Correctly to see the separate test.
Compare with Debt Service Coverage Ratio
Debt service coverage ratio focuses on how a specified cash or earnings measure compares with scheduled interest and principal repayment. A 2.5× net-debt-to-EBITDA result and a 1.5× DSCR are not contradictory; they describe different parts of financial risk. A firm may have manageable leverage but concentrated repayments due soon. The How to Learn Debt Service Coverage Ratio Quickly and Correctly lesson makes the payment calculation explicit.
Why Different Companies Report Different Leverage Multiples
An issuer may use adjusted EBITDA rather than the standard earnings bridge. It may net time deposits against debt, classify leases separately or exclude restricted funds. The multiple can also be based on a trailing twelve-month period or a projected future year. You cannot compare 2.5× from one definition with 2.5× from another and assume identical financial strength. Read and reproduce the stated calculation as far as the disclosures allow.
Debt Maturity and Refinancing Risk
Even a company with strong EBITDA must repay or refinance debt on the dates in its agreements. If several loans mature together, the business may need cash, asset sales or continued lender support. Interest rates and lending appetite can change, making refinancing more expensive or less accessible. Net debt to EBITDA does not reveal the full schedule, so pair it with the borrowing notes and payment calendar.
One More Example: New Borrowing and New Cash
Imagine a company borrows S$200,000 and leaves that amount untouched as freely available cash. Gross debt rises by S$200,000 and eligible cash also rises by S$200,000; simplified net debt is unchanged. The balance sheet now contains more borrowing and more cash, so the company may incur interest cost even though the net-debt numerator is constant. This is one reason to examine gross borrowing and cash interest alongside net leverage rather than relying only on the net amount.
A Practical Company Review Checklist
- List short-term and long-term interest-bearing borrowings.
- Find the cash and equivalents that the definition allows you to subtract.
- Check for restrictions, lease treatment and unusual excluded liabilities.
- Reproduce the annual EBITDA or adjusted EBITDA numerator.
- Divide the values and state the reporting dates.
- Compare trends using consistent definitions and similar business models.
- Review actual cash flow, interest coverage and debt maturity dates.
Common Beginner Mistakes
- Using all liabilities without saying so instead of defined financial debt.
- Subtracting inventory, receivables or restricted cash as if they were free cash.
- Treating EBITDA as actual money available for immediate debt repayment.
- Calling 2.5× proof that the loan can be repaid in exactly 2.5 years.
- Mixing EBITDA from one period with a debt balance from an unrelated date.
- Interpreting a negative multiple with negative EBITDA as an ordinary safe leverage ratio.
- Ignoring interest expense, loan maturities and required equipment purchases.

Sources and Final Reminder
The Corporate Finance Institute Net Debt/EBITDA guide and CFI Net Debt explanation discuss the debt, cash and earnings inputs and their limitations. All values in this lesson are fictional. The idea to remember is subtract eligible cash from financial borrowing, compare with defined annual EBITDA, and never confuse the resulting multiple with a cash repayment schedule.
