How do you learn the debt-to-equity ratio quickly and correctly? Think about two ways a business can fund itself: money supplied by owners and money borrowed under agreements. Debt-to-equity, often written D/E, compares debt with shareholders’ equity. It helps reveal how much financing risk may sit behind the company’s assets and profits. A larger ratio can mean a heavier reliance on borrowing, but it is not automatically bad or good without knowing the industry and the company’s ability to make payments. This eduKateSG Finance Quick Notes lesson teaches the calculation, a Singapore-dollar worked example and a common mistake: treating every liability as if it were the same kind of debt.
- Debt: financial borrowing and related obligations included under the selected definition.
- Equity: shareholders’ recorded interest in company net assets.
- Basic financial-debt D/E: interest-bearing debt ÷ shareholders’ equity.
- State your definition: some analysts use total liabilities ÷ equity, producing a different ratio.
- Read the number: 0.5× means S$0.50 of the chosen debt measure for each S$1 of book equity.
- Check repayment ability: cash flow, due dates, interest costs and covenants matter.
- Compare similar companies: borrowing needs differ by business model.
Teaching paragraph 1 — learn what belongs on each side. Suppose a fictional company borrows S$10 million under a short-term facility and S$20 million under long-term debt agreements. Together, interest-bearing borrowings total S$30 million. Separately, its financial statements show S$60 million in shareholders’ equity. Equity is not just a pile of cash sitting in a bank account; it is the accounting remainder after liabilities are deducted from assets. We will use the financial-debt definition for this example. A supplier invoice is a liability, but it is not automatically interest-bearing borrowing under this particular formula.
Teaching paragraph 2 — divide to get the ratio. Divide S$30 million of the defined debt by S$60 million of shareholders’ equity. The result is 0.5×, sometimes written 50%. That means the company has fifty cents of the included borrowing for each dollar of book equity. The calculation does not mean it must repay half its equity immediately, nor that it owes 50% of its annual revenue. It compares two amounts from the balance sheet at a relevant date, not monthly debt instalments with monthly salary.
Teaching paragraph 3 — change debt while equity stays the same. Imagine the company adds S$30 million of borrowing and its relevant book equity remains S$60 million under our simplified assumption. Total debt becomes S$60 million and financial-debt D/E rises to 1.0×. The increase shows greater financing reliance on debt. Whether the borrowing is sensible depends on what it funds, the interest rate, the repayment schedule and the cash the business can generate. Borrowing to purchase valuable equipment and borrowing to cover persistent operating losses should not automatically be treated alike.
The Beginner’s Debt-to-Equity Formula
Financial-debt D/E = total interest-bearing financial debt ÷ shareholders’ equity. The result is normally expressed in times, such as 0.5×. Some textbooks and financial databases use total liabilities divided by shareholders’ equity instead. These definitions are not interchangeable. Before comparing two companies, read the formula used by each source and decide whether lease obligations and other debt-like items are included.
Worked Example: S$30 Million of Debt
- Short-term financial borrowings: S$10 million.
- Long-term financial borrowings: S$20 million.
- Total included debt: S$30 million.
- Shareholders’ equity: S$60 million.
- Financial-debt D/E: 30 ÷ 60 = 0.5×.
- After a hypothetical additional S$30 million of borrowing with equity unchanged: 60 ÷ 60 = 1.0×.
The new borrowing also changes the company’s assets and liabilities in real accounting records, even though we have held equity unchanged to isolate the ratio effect. If borrowed cash is used to purchase an asset, both sides of the balance sheet need recording. Debt is not automatically income or a gain in net worth. The ratio tells you something about financing structure, not why a loan was taken.
Debt and Liabilities Are Not Always the Same
The term liabilities covers obligations such as loans, supplier payables, accrued expenses, deferred revenue and other amounts. The term financial debt often focuses on borrowing and debt-like funding arrangements. In our example, if a company also had S$15 million in trade payables, a total-liabilities-to-equity calculation might be higher than financial-debt-to-equity. The exact treatment of lease liabilities and other obligations depends on the analysis. Always label the numerator.
A Second Version of the Ratio
Suppose a company has S$30 million of financial borrowings, S$15 million of other liabilities and S$60 million of shareholders’ equity. Under a simple total-liabilities definition, the ratio would be (30 + 15) ÷ 60 = 0.75×. Under the financial-debt definition, it remains 0.5×. Neither arithmetic answer is intrinsically wrong; the problems arise when one number is described as the other or used in a comparison without disclosure.
What Does a Higher Debt-to-Equity Ratio Suggest?
All else equal, more debt relative to equity means a greater proportion of a company’s financing is represented by debt obligations. Those obligations may require interest payments, principal repayment and compliance with lender conditions. More debt can make losses more painful when business conditions deteriorate, but it can also provide financing for productive investments. The ratio identifies a question about leverage; it does not answer whether the borrowed money was used wisely.
Why a Lower Ratio Is Not Automatically Better
A company with very little debt may be financially conservative, but it could also be missing sensible opportunities or operating with an unusual capital structure. A company with a higher ratio may have stable contractual revenue and a repayment schedule suited to its cash flows. There is no one D/E threshold that fits every business. Compare relevant peers and the risks particular to the company’s industry.
Debt-to-Equity Versus Debt-to-Income
Debt-to-equity is a company leverage measure using balance-sheet debt and shareholders’ equity. Debt-to-income typically compares monthly debt repayments with monthly income for a person or household. The two are different both in what they divide and what they can tell you. Do not use a company’s debt-to-equity formula to decide how much a family can borrow based on salary.
Why Cash Flow Matters More Than a Ratio Alone
A business may have a moderate D/E but still face a severe cash shortage if much of its debt becomes due next month. Another firm may have a high ratio but long-dated debt and reliable operating cash flows. To assess repayment ability, examine interest expenses, operating cash flows, debt maturities and committed financing arrangements. See How to Learn Free Cash Flow Quickly and Correctly and How to Learn Cash Flow Quickly and Correctly for the movement and timing of money.
What Are Debt Covenants?
Some lending contracts contain promises or restrictions known as covenants. Examples can include reporting duties, limits on additional borrowing or requirements to maintain certain financial ratios. A firm might face consequences if it breaches a covenant, even before the scheduled maturity of a loan. Read loan notes and financial-statement disclosures for significant restrictions. Never assume that a comfortable headline D/E eliminates contractual risk.
Why Equity Can Change Without New Borrowing
Shareholders’ equity can rise when a company retains profits or issues new shares, and it may fall with losses, buybacks or distributions, according to accounting rules. That changes the D/E denominator. A ratio can therefore rise even when financial debt is flat, simply because equity has declined. For example, S$30 million debt divided by S$30 million equity gives 1.0×, compared with 0.5× when equity was S$60 million. Always investigate both sides.
What If Shareholders’ Equity Is Very Small or Negative?
When equity is near zero, even modest borrowing can produce an extremely high ratio. If equity is zero, the formula cannot be evaluated by ordinary division. If equity is negative, a negative numerical result may not give a sensible picture of leverage. The correct step is to examine the financial position in detail, including accumulated losses and the nature of assets and obligations. A negative D/E should not be celebrated as evidence of no risk.
Debt Maturity Is Another Essential Question
- How much borrowing is due within the next twelve months?
- How much remains due in later years?
- Is the interest rate fixed or variable?
- What happens if financing becomes more expensive at renewal?
- Does the company have cash or reliable incoming funds for the due dates?
- Are lenders secured by particular assets or entitled to special protections?
- Does the business depend on recurring refinancing to continue operating?
A debt schedule lays out repayment amounts and dates. It can reveal a large maturity that a single debt-to-equity figure hides. The same debt amount can create very different risks depending on whether repayment is due next week or over several years.
Debt-to-Equity and Return on Equity
Debt can influence how much profit is generated relative to the shareholders’ equity base. If borrowing funds productive investments, shareholders may benefit, but financing costs and financial risk also increase. A high return on equity can sometimes coexist with heavy leverage or unusually low book equity. Read How to Learn Return on Equity Quickly and Correctly to distinguish operating strength from ratios inflated by the financing structure.
Common Beginner Mistakes
- Treating all liabilities as interest-bearing borrowings without stating a definition.
- Dividing debt by total assets and calling it debt-to-equity.
- Assuming a debt ratio measures monthly repayment affordability.
- Ignoring changes in equity after losses or buybacks.
- Assuming a ratio above one automatically means imminent bankruptcy.
- Ignoring repayment dates, floating-rate exposure and covenant conditions.
- Comparing companies whose debt definitions or accounting standards differ.
Ten-Minute Debt-to-Equity Practice
- Minutes 1–2: define borrowings, liabilities and shareholders’ equity.
- Minutes 3–4: calculate 20 ÷ 40 for an imaginary company, with amounts in millions.
- Minutes 5–6: add S$10 million of debt with the equity unchanged.
- Minutes 7–8: add a non-interest-bearing payable and explain which D/E definition changes.
- Minutes 9–10: name two risks the simple ratio cannot reveal.

Verified Reading and Final Rule
The Corporate Finance Institute debt-to-equity guide uses debt and financial obligations relative to equity; CFI’s accounting-ratios overview also illustrates a total-liabilities definition. The OpenStax Finance Chapter 6 summary places D/E among solvency ratios. These Quick Notes teach the math and interpretation, not an investment recommendation. Remember: debt-to-equity is a comparison of financing with book equity, and its definition and repayment context must be made clear.
